Title: I think my 5970 should be working harder than it is. Post by: nemo on June 28, 2011, 05:11:37 AM How any Mhashes are you guys pulling per GPU on this card? I get around 360 when I know I should be getting more like 400. I don't water cool though, instead I have a fan keeping it around mid 70s.

Title: Re: I think my 5970 should be working harder than it is. Post by: nemo on June 29, 2011, 06:26:08 AM I'm using Phoenix Miner, and my settings are -k poclbm DEVICE=0 AGGRESSION=12 WORKSIZE=128 VECTORS BFI_INT
I've overclocked to 850mhz and my ram is at 300mhz. Temps are currently 75 and 79 degrees C I'm actually getting around 350 mhashes a GPU, not the 360 previously reported.

Post by: godofal on June 29, 2011, 03:21:52 PM i always thought this (https://en.bitcoin.it/wiki/Mining_hardware_comparison) page is undervalued/used
i try to aim for the top 3 mostly, if i can get around those numbers i think ive pretty much maxed the card Title: Re: I think my 5970 should be working harder than it is. Post by: Jack of Diamonds on June 29, 2011, 03:28:36 PM 360 per core is actually pretty good.
I can't get my 6990 cores much past that without significant overclocking. Even then it will hit about 380 max, maybe 800mhash/s total if I really tweaked around with the settings. Consider that a 5970 is at least 100-150 bucks cheaper so it's a bargain if you find one. Title: Re: I think my 5970 should be working harder than it is. Post by: nemo on June 29, 2011, 11:13:17 PM Quote I can't get under 500 regardless of how much I play with afterburner :( You have to set it to 500, hit apply, then close it. Then open it back up and you can go much lower than 500. I will try the new kernel and let you know how it went. Edit: I'm hitting 370 a card now. I hate myself for not doing this earlier.

Anybody posting the "extreme" hash rates is most definitely using water cooling. You cannot achieve those rates without water cooling. Title: Re: I think my 5970 should be working harder than it is. Post by: nemo on June 29, 2011, 11:54:58 PM Yea, I just noticed that this card can go over 820, but the clock rate is at 950. Not even going to think about pushing it that hard.
Title: Re: I think my 5970 should be working harder than it is. Post by: lechuck on June 30, 2011, 10:40:02 AM my 6950 has lost around 60Mh/s when i installed the most recent catalyst drivers, so maybe thats also an issue with your card? after rverting to the old driver version I gotthe 60mhs back!
Title: Re: I think my 5970 should be working harder than it is. Post by: Keninishna on June 30, 2011, 10:59:40 AM Also don't forget some tweaks can push you to the 370+ range. Here is a modified phatk kernel I use http://forum.bitcoin.org/index.php?topic=7964.0 (http://forum.bitcoin.org/index.php?topic=7964.0) and here is a tweak +3-5% hashrate http://forum.bitcoin.org/index.php?topic=23067.0 (http://forum.bitcoin.org/index.php?topic=23067.0)
Title: Re: I think my 5970 should be working harder than it is. Post by: sunbird on September 15, 2011, 02:58:15 PM Hi all,
I've got a little bit of a different problem, but thought I'd post here since it concerns a 5970 card. I'm running ubuntu 11.04 with ati-sdk 2.4 and catalyst 11-8. mining is working on each core, but if i run workers on both cores at the same time, the hash rate drops by 50%. Do I need to get dummy plugs? Or is something else going on? Once I get both cores working independently of each other, I'll work on upping the hash rate. Any help appreciated!

Do I need to get dummy plugs? Or is something else going on? Once I get both cores working independently of each other, I'll work on upping the hash rate. Any help appreciated! There's no never been a need for dummy plugs on Linux. Try to use cgminer. It should detect all cores at once and mine on all of them. If a core doesn't get detected, you'll know at once. Hi, Thanks for the response. Actually, the problem is not with detection: Code: [0] Cypress When I run a phoenix miner on device0, i get ~ 316 Mhash/sec and loads on Device0=99%. But when I start a second phoenix miner on device1, it starts, works fine, but I get this result on the miner running on Device0: Code: Kernel error: Unusual behavior from OpenCL. Hardware problem? And the loads look like this: Code: # aticonfig --odgc --adapter=ALL I can run either miner independently of the other without getting the error. Also, FWIW, I have crossfire chains disabled: Code: # aticonfig --lsch Also, I will go ahead and install cgminer... maybe all the problems will go away! I'll report back after I do so. Okay, here's my cgminer install, which is working, but no better than the other miners: Code: cgminer version 2.0.2 - Started: [2011-09-15 21:33:41] Title: Re: I think my 5970 should be working harder than it is. Post by: sunbird on September 16, 2011, 01:49:11 PM Code: cgminer version 2.0.2 - Started: [2011-09-15 21:33:41] Ugh, that doesn't look good. My bet is that your GPU is somehow faulty. The reject rate also tends to point in that direction. I'm not convinced that it is the card, especially since each core works on its own @ 300ish Mhash. But I will pull everything apart this weekend and put it back together. Perhaps there is a loose connection. Title: Re: I think my 5970 should be working harder than it is. Post by: turquoise9955 on September 17, 2011, 09:35:21 AM Is it overheated at all?
Title: Re: I think my 5970 should be working harder than it is. Post by: sunbird on September 17, 2011, 04:53:04 PM Is it overheated at all? No, temps are totally normal, in fact, low. I'm going to take the box apart today. I wish I knew someone locally (Seattle) with a 5970 so I could just swap it out, that would be the easiest way to isolate the problem. The MB, PSU, CPU are all new. So I'd like to figure out if one of them is bad quickly so I can RMA if necessary. Edit: Well, no dice. I took everything apart and put it back together and still can't seem to get this card working hard enough. I will try some other diagnostics on the card, but would definitely welcome any suggestions from the group. Second edit: Solved it! So the problem is apparently with the 11.8 ATI drivers. I used the 11.5 ATI drivers instead and now things are working beautifully! I even added in an old 4800 card that a friend wasn't using anymore, so I'm getting (on stock clocks) about 680 Mhash out of the two cards. I'm sure I can tweak it upwards from there.

Post by: trasp on September 18, 2011, 03:09:05 AM Quote DISPLAY=:0 aticonfig --od-setclocks=840,416 --adapter=2 DISPLAY=:0 aticonfig --od-setclocks=870,416 --adapter=3 Gives me 360-365MH/s respectively 379-386MH/s... could push the first one up to 845-850 something if I didn't have a 6990 over it. (the VRM's is getting bbq'd) This is on the other hand very good... A shop gave me seven 6990 out of eight 5970 ordered and thought they were nice to me, they can't pull air from the sides, they blow hot air into my case which kills all my other equipment, pulls about 50W more energy a piece which ment I had to buy new PSU's and gives me the same 379-386MH/s! But hey, they cost more, so they must be better for everyone, right..? Edit: Using DiabloMiner-Linux -v 2 -w 128, SDK 2.5 and driver 11.7. Just upgraded to 11.8 though which seems to give me slightly less hashes in average and alot more variance, allthough I just might need to balance the clocks a degree or two. The 6990 is now getting slightly higher speeds and seems more stable. Linux 11.8-drivers is not the same as the windows ones Title: Re: I think my 5970 should be working harder than it is.

Title: Re: I think my 5970 should be working harder than it is. Post by: jjiimm_64 on September 24, 2011, 07:11:59 AM sounds right. I am getting 377 mh 850/400 temps at 79
Title: Re: I think my 5970 should be working harder than it is. Post by: DeathAndTaxes on September 27, 2011, 09:14:50 PM 410MH/s per core @ 920/300 (except one core which won't go above 900MHz).
It is all about the cooling. Running 1.125V @50C. Title: Re: I think my 5970 should be working harder than it is. Post by: d.james on October 17, 2011, 04:16:19 PM :o 50C? must be using some nice waterblocks.
