Title: 5970 mining thread Post by: jjshabadoo on December 22, 2011, 12:35:56 AM I thought it might be worthwhile to create an ongoing thread for those of us with 5970's to share info about clocks, voltage, cooling, mining software settings, etc.
Since many people have recently purchased these from newegg, etc. it might help us to optimize these cards to their full potential. My current set-up is: 2 identical rigs MSI 890FXA-GD70 AMD sempron 145 sargas 2.8GHz 45 watt crucial 2x1gb ddr3 1066 ram seasonic X750 watt gold psu 2 x ati 5970 video cards at 800gpu/300mem 16gb USB flash drive with linuxcoin final I used 2 old computer cases with all hard drive cages and anything extra removed. I am using cgminer 2.0.7 My average hash rate is 1.4GH/s on each machine or 700MH/s on each card average gpu temps are 50-60c depending on card placement, each card is also slightly different. I have not monitored VRM temps yet. I plan on adding two more 5970's to each machine with a daisy chained seasonic X750 and a custom rack to hold the GPU's with pci x16 molex powered extenders. I have also removed the stock cooling on the four cards I am not using and in the process of replacing the thermal paste and thermal pads. I will post when I get the cards working properly again. Any suggestions on replacing the pads and TIM are appreciated. I plan to use .5mm thermal pads for the ram and other cooling points and 1mm pads for the VRMs. I will use arctic MX3 on the GPU's and plan on experimenting with shin-etsu X23-7783D if I can get it to spread properly!

Its not daisychained, noob.... jesus b4 you break your cards, just leave it be and hash without down time.

Ok, so I'm a noob with using multiple PSU's, does that matter? I'm here to learn and improve and possibly help others. The title of my post was not " The definitive guide to using four ati 5970's on one mobo" Thanks for the constructive advice though. I didn't get into this to make money, I enjoy hardware as a hobby.

My advice: dont tinker with things you dont know or not sure about. Leave those cards intact, instead focus on custom box to drive cool air to the cards. More efficient that way. Title: Re: 5970 mining thread Post by: jjshabadoo on December 22, 2011, 08:46:58 PM I see your point, but I want to learn and although my purpose isn't to ruin a graphics card in the process, I'm willing to take that risk.
I've built custom water cooling loops before without issue and have never run into a graphics card which needed different size pads, etc. Of course I have never put a water block on a dual GPU before either. Also in another thread I meant to say 1mm pads for ram and .5 pads for VRM. I shouldn't have posted the opposite in case someone screws that up. Nonetheless, I'll refrain from posting any advice about hardware in the future and leave it to others. I'll simply post results like hash rates, software settings, etc. Thanks for the advice anyway however harsh your delivery may be. I'll send you a 5970 if I burn one up. Maybe you can fix it and mine some coins for yourself. Title: Re: 5970 mining thread Post by: Unacceptable on December 22, 2011, 10:24:05 PM Have you ever used Ceramique??

Title: Re: 5970 mining thread Post by: deepceleron on December 23, 2011, 08:47:44 AM Quit goofing around and leave the machines up and mining, I guarantee you will make more plopping together a stock system and leaving it alone than you could make up for the downtime trying to tweak overclocking and installing drivers and different software. Just use some big case fans or pull the systems out of the case.

I enjoy tweaking hardware and learning. Also, I did get the TIM and pads properly installed last night and it worked great.
I'm running two 5970's at 850/300 at max 58c and that is without the pci extenders and such I will eventually use on the custom case I'm building. So to me it's worth it just to learn. For those who want maximum bitcoin production you guys are absolutely correct, just set them up, slight OC and go. I also build custom gaming PC's on occasion so this is all useful for me to learn. Those machines are all about max potential and you never get that with stock cooling, etc. Title: Re: 5970 mining thread Post by: jjiimm_64 on December 24, 2011, 01:53:36 AM I hear ya, but my purpose in doing this is beyond maximum bitcoin mining potential.

Title: Re: 5970 mining thread Post by: jjshabadoo on December 26, 2011, 09:14:25 PM I'll get some validation soon Jimm. I am running these rigs in a very cold basement right now with no heat on the east coast. I am SURE they won't run at 850 once it gets warmer.
They do have to be reset fairly regularly though at those clocks, about every 12 hours, so not very stable yet. I'm building a rack of fans to blow into the cards and see if that makes it stable longer. For now I clocked them down to 800/300 and they have been running for a couple days without problems mining 24/7. I didn't want to tinker with anything due to the holiday and also because we caught some long blocks in our pool recently. I mine at Eclipse also. I figured I didn't want to power down my rigs until we chewed through that last long block..lol. Title: Re: 5970 mining thread Post by: dmcurser on December 26, 2011, 09:55:42 PM ok after a little bit of playing with both afterburner and cg miner i got my 5970 to 920/150 and the voltage in afterburner is 1149 with temps at 67 degree Celsius i haven't taken these apart but i think i am going to do so in the near future at-lest the one bc the vram i think is at like 106 when all the rest are sitting at about 90 so i think it needs new thermal pads and hell while im at it new thermal paste anyone know of any good thermal paste and pads to use?

I would love to run mine at that, I have 21 of those cards.. anything over 820 is unstable for me. w/ memclock down to 190 I can get 835 on 12 5970s. I have 4 watercooled and I can push all of them to 865 w/o problem except one. Temps are <50C but anything higher than 865 requires more voltage. I had them 100% solid at 880 watercooled but overvolting doesn't seem worth it w/ current prices. The GPU driving the physical monitors can't be pushed beyond 830 without lots of instability. So yes higher clocks are possible.

I'm OK with software but hardware is magic to me. I'd appreciate a brief tutorial (a sentence or three) on how the voltage parameter relates to the other ones.

I'd appreciate a brief tutorial (a sentence or three) on how the voltage parameter relates to the other ones. burning them in at stock is a good to do. I also used them for a while at lower clocks. I probably will not mess with the volting. happy to let them cruise at 745Mh per card Title: Re: 5970 mining thread Post by: Red Emerald on December 27, 2011, 06:18:53 AM I just have one 5970 that is unbranded (so Dell). I almost bought a second but then they became impossible to find.
I first had it set to 835/300, but it crashed after a few days. It's been really stable at 830/300 since June on stock air cooling in an ACd server room so it never gets above 75C with 85% fans. It's in a spare antec 1200. I would love to build a custom case for the nerdgasm, but I have other projects to work on.

You're also using two seasonic 750watt gold psus.
I just reset my rigs and used a lian li power supply adapter to get both psus running. I have been able to get three cards going on each rig for now, but I couldn't get a fourth going. I used pcix16 slots 1,3,5,6 like the MSI manual suggested and also tried 1,4,5,6. I'm using the molex powered x16 extenders from cablesaurus as well. Any suggestions or tips? Thanks. Oh and I have one power supply powering two cards and the CPU with one molex rail connected to two extenders. The second psu is/was connected to the other two cards and one molex rail to power the other extenders.

I do not use molex powered extenders. not needed, just use regular ones if you have them I try not to use molex plugs unless I am forced to . as for seeing all four cards, most times all four show up OK. but for stubborn rigs I just keep moving things around and redoing the drivers until it works. sometimes I have to reset the bios on mobo. what operating system? all of my 4X5970 rigs are linuxcoin on a stick Title: Re: 5970 mining thread Post by: jjshabadoo on December 29, 2011, 05:15:22 PM Yeah, I use Linuxcoin also, the final version on a usb stick. I follow the headless instructions from the Wiki.
If I already have powered extenders, can I just not plug in the molex? Could that be screwing things up?

my cgminer mining script looks like this if you were using one 5970 ./cgminer -o http://miningpool:port -u username -p password -I,9,9 --gpu-fan 85 --gpu-engine 800 --gpu-memclock 300 This gets about 700-725 MH/s for a single card average about 710 MH/s or so. This is for a stock Diamond card from newegg. I am testing some cards that I redid the TIM and thermal pads on and have those at --gpu-engine 825 --gpu-memclock 300 Those are getting an about 730-750 MH/s for an average of 740 Mh/s or so. For three cards I'm using same as above, but I,9,9,9,9,9,9. Title: Re: 5970 mining thread Post by: Proofer on December 29, 2011, 05:37:49 PM Here's the relevant portion of my cgminer.conf:

I'm messing around with it and learning all kinds of things. One question-- how does memclock affect things in terms of energy usage and hashrate?
Title: Re: 5970 mining thread Post by: jjshabadoo on December 29, 2011, 07:59:29 PM lower memclock = lower energy use
It also increases hashrate slightly I believe, but it definitely lowers energy use which is huge. Some people have gotten the memclock as low as 160 I think. You have to mess around with settings to see what works best. DeathandTaxes has done alot of screwing around with 5970's and can probably add more to this discussion than i can.

You have to mess around with settings to see what works best. In my current series of experiments I have memclock at 150. 810 on the engine clock was looking good until this morning when GPU 3, which seems to be my problem child, hung. So now I've got it at 800 and the other five at 810. We'll see...

IIRC, for some vector settings, hashrate increased with clocks, but the fastest performance was achieved with other settings and very low memory clocks.

Got a minor increase in shares per minute (which matters more than hashrate). ... Is there a theory about the relation between hash rate and shares/minute? Overall they must correlate, but I've observed that the correlation is not perfect. Exactly. IF rejected shares are the same then hashrate and share rate should correlate. There is short term variance but over say 24 hours you shouldn't see a lower hashrate and higher share rate. Now IF you have rejects not related to pool latency then your cards are trying to tell you something. It is possible to drive the card to the point of failure such that despite the higher hashrate you have some many rejects that shares/min is lower. Of course this should be immediately obvious with the giant ugly number next to R. :) U (is in shares/ minute) = (hashrate * 60) / (2^32) If you reject rate is >0% then it will affect U but the amount should be small because w/ modern miners there is no reason for a reject rate higher than 0.1%. So for example 400 MH/s = (400 * 1000^2 * 60) / (2^32) = 5.58 shares per min Title: Re: 5970 mining thread Post by: jjshabadoo on January 03, 2012, 02:33:55 AM Speaking of clocks and hash rates, I vastly over stated what I thought I could get earlier in this thread. Right now my cards won't go longer than 2-3 days at 800/300 or 800/160 and this is in a cold basement. One machine has a box fan blowing on it directly.
It has to be the ram, because my core temps don't go above 60c and most are in the low 50's. I'm starting to think these diamond brand 5970's from newegg just suck. I just cranked them down to 725/160 since I won't be able to mess with my rigs for a while. I'm thinking I might have to go water cooling since I can probably get 900 or so. DeathandTaxes, what hash rate do you get on your water cooled cards. I'd like to do some calculations on the difference to see if a water cooling investment is worth it. Title: Re: 5970 mining thread Post by: jjiimm_64 on January 03, 2012, 02:41:14 AM It has been my experience that the 5970's run more stable with a little higher memory. I used to run them at 420, i have since brought it down to 300. I know I am not answering the water cooling question. I would raise the mem back up a bit if it was me. Also, did you burn them in at a lower clock before going above or at 800? I did for all 21 of my 5970's. I ran them at stock clock for a few hours, then at 750 for a while, then at 775 for a day. after that I would run them at 800/300 for a stability check. (days). after that maybe crank them up to 820 if the temps are OK. just my 2 bitcents. Title: Re: 5970 mining thread Post by: jjshabadoo on January 03, 2012, 03:30:43 AM I appreciate the response Jimm and no I didn't burn them in intially, maybe that screwed me.
I'm just getting frustrated here as I have put in about 20 hours on these rigs the last 4-5 days and it's pissing me off that I can't even get 800 clock speeds after replacing all the TIM and pads, etc. I know I did a good job with the TIM and pads because the GPU cores went down at least 5c on every card. If you guys could see how bad the stock pads and TIM was on these cards you'd know what I did should have helped A LOT. I'm just thinking all the down time and restarts are costing me way more than if I just water cooled every damn card and called it a day. It looks like it would cost me about $1000 per rig for three cards to water cool them. I have 12 5970's and 8 5870's right now. The 5870's are at 900 with stock cooling and have run fine for 4 days. Considering I could probably get the 5970's to 850 or 860, that's 125 mhz per core over stock for a total of 1500 mhz extra. Three cards at stock is getting me about about 2 GH/s at 850 I think I could get closer to 2.4 at least. So that would be an extra 1.6 GH/s which gets about $200 per month at current prices. Now if you count shutdowns and the loss of revenue associated with all that, looks like about a 12 month return. Title: Re: 5970 mining thread Post by: Proofer on January 03, 2012, 03:36:03 AM ...

So I increased memclock from 150 to 300 and reduced engine clock from 800 to 725 (stock speed). I was hopeful, but after about 10 hours one (of six) was just reported "SICK"... This one is reporting about 68C. Maybe I should just accept a certain rate of SICKness? At 800/150 I was getting about seven such cases a day. Title: Re: 5970 mining thread Post by: jjiimm_64 on January 03, 2012, 05:38:04 AM this is also not too scientific.. but some of the rigs I would just keep restarting, keep the clocks at whatever they were. and eventually the rig would just kept running. still dont know why.

also, who said that running the fan at 100% is good... good for the guy that is going to sell you another card maybe. 100%? Comments? (Replacement fans are US$ 15 each on eBay.) Title: Re: 5970 mining thread Post by: P4man on January 04, 2012, 07:44:50 AM Fan bearings will wear out sooner or later. I strongly suspect the relationship with fan speed is at least linear, possibly super linear as vibration is likely a very important factor (avoid speeds which produce more mechanical noise, humming etc).
Of course you can get lucky. Or maybe that poster has some advantages most other miners do not, like a dust free environment or he lubricates them regularly. Either way there is little doubt in my mind a fan at 100% wont last as long as one on 50% and its not like fan failure is a rare thing. Its equally true low temps will help the card live longer, but it all depends how high your temps are. I get <60C with fans at 50% (non ref cards), its pointless to increase fan speed in those circumstances.

Title: Re: 5970 mining thread Post by: The-Real-Link on April 13, 2012, 09:07:52 PM Hey guys, sorry to bump this general 5970 thread but had an interesting issue come up.
Been mining with a few of them fine for months now. Two were starting to show massive crashes and instability (810 core, 500 memory, stock volts) despite temps being in the low to mid 70s. Bumped everything back down to stock but the issues remained. Thankfully they were both Diamond models from Newegg so I could show legit purchase receipts. So anyway, pulled the cards, sent 'em back...and waiting. This was maybe a month and a half ago. Once stuff arrived at their RMA office, I figure testing does take time so I wanted to be patient. Now that it's been a month, I finally was back in touch with Diamond seeing as how I've heard nothing via email back. Their tech, Chris, was quite helpful and apologized. Now here's the concern for others of us out there with these cards. He said normally if a card is bad (and both of mine were confirmed as being such), they'd replace it immediately (makes sense). But Diamond themselves are still waiting from AMD for more cards and they are either not coming or taking forever. As such, we can only wait. An upgrade was offered but since they also have no stock of 6990s, I can't go that route. He said he'd look into offering a 6970 or a 7970 which, given the price, warranty and newness of a 7970, would seem stupid for me not to accept should they validate it. I know I'd probably get maybe 75% of the hashing power of a 5970 out of a 7970 but at this rate, I can't see any other choices open to me. Just a heads up for anyone else running on these old cards. Should they bite the dust, you might be in for quite a wait in terms of a replacement, if any, or maybe an upgrade. While I figured this was true to an extent when buying the cards, I had presumed manufacturers still had some stock left. Apparently not. Title: Re: 5970 mining thread Post by: DeathAndTaxes on April 13, 2012, 09:24:34 PM Thanks for the info. Yeah I figured the 5970 would eventually be out of stock but I always assumed they would give you a 6990. A 6970 is a dog of a deal. At least with 7970 you get some improves power efficiency and easier cooling (due to single GPU design).
Title: Re: 5970 mining thread Post by: MrTeal on April 13, 2012, 09:28:15 PM Does anyone know of a source for the VT1157SF VRMs used in this cards? I had one go out, and need a replacement. Emailing Volterra didn't help, since they do not have distributors for their chips.

~780 Mhz to 840 Mhz depending on the card. I would put the avg somewhere around 800. Memclock is 210 Mhz for all cards.

You can't change the fan speed for them all but you can still move the clock sliders.
Update on my end. Diamond told me they could trade me two 6970s for my cards dying. I'd have to pay extra to step up to 7970s.

If you dump your bios from the card and open it in RBE and you see that "GPU Registers" is available you can use that to set the vcore down to 0,1-0,15 increments at least(didn't bother to check smaller changes, important is to not touch the vcore settings for the profiles but only change it in GPU registers if you want to flash the cards). And yes I have confirmed that the changes do actually take place and affect power usage. If the card (most ref boards) is recognized in MSI AB it seems to be able to change it in these small increments as well while other software seems to be working on another level (no fucking idea how it works, error and trial is my way!)
Cards that do not have "GPU registers" available are the cards that get's stuck in the "steps" no matter what, they vary from different boards from different manufacturers and only testing can really determine what vcore they actually run at. ALSO on these boards and the REF boards you can set vcore with some software (Asus gpu tweak in my case, AB couldn't change it at all on the boards without accessible gpu registers) and for example GPU-Z reports the new vcore you set but it doesn't change/or simply goes to the next "step" while still displaying the wrong vcore, I still don't believe there are 5870s running at 850Mhz with 0,899V, why I started testing wth was going on in the first place! :p Back on topic! I've tested my only 5970 (ref board, all changes done by bios flash and editing the GPU registers) and it does have "steps" but seems to be around 0,13V (0,899V, 0,912V, 0,925V, reverts to these values when you set 0,9 0,91 0,92 etc) tested all 3 and both power usage and max stable frequency changed by about 3-5W at same speed and 10-15Mhz for how high it could go. Edit, might add i'm currently running my 5970 at 0,899V and 625/300, can do a bit higher but it's mostly to be sure about 24/7 stability. The card pulls around 145W from the wall on a 80+ bronze psu.

I like PowerColor, Sapphire, and Asus. A lot of people have good luck with Gigabyte. I've heard to stay away from XFX and Diamond, but again, YMMV. There is no BEST brand for OCing. Also, while a 5970 is technically 2x 5870s in one card, the voltages are lower to keep the power/temps down. Stock voltage on a 5870 is 1.174, while stock voltage on a 5970 is 1.050. If you lowered your 5870 down to 1.05, you won't be getting 450MH/s. If you raised your 5970 to 1.174, you MIGHT be able to get 400+ per core, but it would be a very bad idea. Power draw increases, temps become too much for the shared cooler, and your VRM temps would be through the roof. Not a good idea. Side note: Here are my 5870 speeds, for undervolting comparison: 460MH/s - 980/300/1.174 - My "all out" setting 425MH/s - 925/300/1.000 - My "max profit" setting 350MH/s - 755/300/0.950 - My "keep the temps down" setting. I think my card can get higher clocks at each voltages than average, so yours may be a little lower.

I got my Gigabyte 5870 to 450Mbps without much sweat, which is quite high for a 5870. But my Gigabyte 5970s can't seem to go post 700Mhps without freezing the whole system :/ I'm running them at 180/800MHz/Default voltage Mbps? You mean MH/s? ;) I kid... It's really card dependent. I like PowerColor, Sapphire, and Asus. A lot of people have good luck with Gigabyte. I've heard to stay away from XFX and Diamond, but again, YMMV. There is no BEST brand for OCing. Also, while a 5970 is technically 2x 5870s in one card, the voltages are lower to keep the power/temps down. Stock voltage on a 5870 is 1.174, while stock voltage on a 5970 is 1.050. If you lowered your 5870 down to 1.05, you won't be getting 450MH/s. If you raised your 5970 to 1.174, you MIGHT be able to get 400+ per core, but it would be a very bad idea. Power draw increases, temps become too much for the shared cooler, and your VRM temps would be through the roof. Not a good idea. Side note: Here are my 5870 speeds, for undervolting comparison: 460MH/s - 980/300/1.174 - My "all out" setting 425MH/s - 925/300/1.000 - My "max profit" setting 350MH/s - 755/300/0.950 - My "keep the temps down" setting. I think my card can get higher clocks at each voltages than average, so yours may be a little lower. you should try higher at 0.950v... mine has been stable for 200+ hrs at 830/195/0.950 the next step for me is 940/195/1.112 then 1010/195/1.175 it's xfx non-ref (hmm or maybe a sapphire non-ref... haha) Title: Re: 5970 mining thread Post by: Sant001 on June 25, 2012, 10:07:09 AM How much power one needs to power 3x to 5x 5970s?
I have 2x 5970 at 1200W, the moment I try use 3x the thing gets really unstable and I can just assume it's due to insufficient power. Running them with under clocked memory/default core/default voltage. Title: Re: 5970 mining thread Post by: crazyates on June 25, 2012, 02:36:03 PM How much power one needs to power 3x to 5x 5970s?

Running them with under clocked memory/default core/default voltage. Plan for 200-300 W for each card. I'd say that PSU can handle 3 5970s at stock settings, or 4 if you undervolt. Do you have a killawatt? Title: Re: 5970 mining thread Post by: crazyates on June 25, 2012, 02:37:29 PM What's the best brand for 5970 in terms of overclocking/Mhps?

I'm happy with 925,300,1.000, so that's what I leave it at most of the time.

I have a reference and non-reference running in one rig, no real problems other than the fact that after changing the fan on the non-reference version, one gpu runs much hotter than the other. Sorry, I don't have experience with arctic cooler or black edition 5970s.

i got two readon 5970 i trying them for two days for litecoin mining. i tried many .bat configs but i couldnt made them stable. sometimes they get 90 temperature, sometimes they suddenly stop mining. finally i put them off and inserted my powercolor 7950s actually 5970s are mining about 700khs 7950s are mining 580khs is there a way to run my 5970 stable? Title: Re: 5970 mining thread Post by: dmcurser on December 31, 2013, 04:59:44 AM im guessing you got them used have they been rethermal pasted is the fan spinning up to speed and holding rpm????
Title: Re: 5970 mining thread Post by: deepceleron on December 31, 2013, 05:10:14 AM is there a way to run my 5970 stable? 90 is to hot. You should use software that can control the GPU fan speed and crank it up to max, and put big fans blowing on the cards. Old-skool mining pic of what is appropriate: http://img59.imageshack.us/img59/7679/p1030044o.jpg Also, 5970s are power hogs, the max power rating at stock is 290 watts per card, your power supply might not be able to keep up. |
