i second the open case idea, a lot more freedom and keeps temps down better, not to mention you can really built it yourself for very cheap if you are saving money on it.

i just found that thanks! so i don't want to get my hopes up but it seems like that is exactly what problem I am having.
it's also more possible i will have problems but my dumba** decided to get 12inch risers because i didn't think I'd have enough space for the 19cm(7.5inch) ones which seem to be standard

sorry to bump an old thread, FullLife, I was wondering what you finally did to get all 4 working with risers? I didn't know that you could have pci powered extenders until I saw this thread and this: http://cablesaurus.com/PCIe-x16-Extender-Cable-w-Molex-ConnectorI think this was the exact problem I am always having. sometimes all 4 cards work, other times the bios only sees 2 or 3, sometimes it doesn't want to load at all. Now that I think it through, i have 1 slot that only runs at x16 and won't drop to x8. If I use only one card, with just a riser plugged into this slot it still won't boot properly, but sure enough, if I plug the card directly into that slot it works like a charm. Then I tried plugging one card into another slot that can drop to x8 with the riser by itself and that works, but then I was having trouble with all the other combinations, and I think the powered riser might be the solution. edit: hell this might even be the reason my cards aren't able to reach their full potential now that I think of it, but it could be wishful thinking |

how'd you get to 600kh with it? I'm stuck at 500kh with mine

anyone have any luck with sapphire's trixx program? https://www.sapphireselectclub.com/ssc/trixx/trixx.aspxit looks like it should be able to allow us to change the voltage on the vapor-x GHz 7970's (among others) there's a list at the bottom of that link which tells which features are supported for which cards. |

Mining works, but website is down.... :S That's what I thought too, but the website was up for a brief time this morning and NONE of the work I did yesterday showed up. Also zero auto payouts and I have it set to 1LTC, there should have been several by now. It appears to be working fine, but I think the shares are going into the void. Sorry about the late update. We are definitely under DDoS. I had shifted the site away from the DDoS service to see if stales improved and within a few hours we were under attack and down again. The attack caused some crons to fail. The crons lock and unlock as they start and finish so when the ddos interrupted them they stopped running until I manually cleared the locks. Once I did that, all the block payouts caught up and paid out, though because of the ddos, payouts today sucked anyway. I did make some progress today toward shifting to the new server. I think by tomorrow i'll be able to move all the DB services over to it. A couple people have pointed me at the elgius pool software for stratum. It looks promising. I'll give it a whirl soon! Cheers. mattz0r, probably still being ddos'd see above quote. It would be nice if it were down because of stratum implementation though  |

I think I had them disabled already, but just for kicks I enabled one of the buttons on one card .. it destroyed the hashrate and now cgminer reports it as "sick" whatever that means  as an update, before i tried to push that blue button, i upgraded to 13.10 drivers and it got me about 5 more kh so I was at 525kh for each card... now i'm wrestling to get all 4 working again ... don't push that button! Since the button just enables a second BIOS, I’d try powering the whole machine off completely, then disable the buttons and power it back on. That should put you right back to where you were. i did this, then when it came back up from rebooting, bam! cgminer only saw 2 cards again. so I went into my bios (asus rampage iv) which has a GPU post menu to see what GPUs the bios sees. It seems that some times when I boot, it only sees 2, other times it sees 3, i've only had it see all 4 about twice. i searched through the manual over and over to no avail. There's an 'ez_plug' which is supposedly extra power for the pci-e slots, but i thought this is not needed if each card receives its own power (each from its own rail which is how i have it setup). Maybe the bios needs the extra juice to just turn on all 4 slots at once. I'll see about how to get an extra plug in there, maybe that's it. (wishful thinking lol) edit: did some research on this and it turns out that you are supposed to plug in the ez_plug when running 4 GPUs which is an additional 6pin PCIe connector, which I seem to be lacking on my silverstone st1500... with 4 gpus, it takes up all the pcie connections, so I am going to have to use one of those dual molex to 6 pin adapters to get the extra power. I guess it allows extra power to the x16 only slot to be able to turn on when there's 3 other gpus plugged into pcie slots 2,3 and 4... oh well I guess i'll settle for 2 gpus mining until i can get to the store for that connector :/ in other news, the powerboost button, I turned it off on that one card, and have rebooted/reseated it several times and cgminer just keeps reporting it as being sick, then dead after 15 minutes. It was working flawlessly (at the same crappy 525kh/s) prior to pushing that button. I think since I have time, I will exchange it for one of the gigabyte versions that FullLife mentioned since he was able to get ~720 kh with it. If that works with similar settings etc, I will probably exchange all three for that card. |

yes, i believe it does because when you lower the gpu memory very low, the hashrate suffers

does it show the GPUs in the list once it starts running?
it should show all the possible mining targets that it is setup for, so if you had 2 gpus it should show those on the list (in my experience anyway).
I had an issue where I had to rerun the aticonfig command once I added more GPUs or it would not recognize them. Mine does not allow me to mine on the CPU however, so I don't know any more than that currently
if i write: cgminer -n, i get: [2013-04-07 15:14:09] CL Platform 0 vendor: Advanced Micro Devices, Inc. [2013-04-07 15:14:09] CL Platform 0 name: AMD Accelerated Parallel Processing [2013-04-07 15:14:09] CL Platform 0 version: OpenCL 1.1 AMD-APP-SDK-v2.4 (595.10) [2013-04-07 15:14:09] Platform 0 devices: 2 [2013-04-07 15:14:09] 0 Cypress [2013-04-07 15:14:09] 1 Cypress [2013-04-07 15:14:09] 2 GPU devices max detected I think that the gpus are correctly configured. I will try to update the driver. I think i had to reinstall the driver after I booted the system with all cards plugged in. The driver would not auto activate all cards. So if you install the drivers with 1 card plugged in, then restart and plug all of them in, I had trouble getting it to show them all. Then i reinstalled the drivers while the system had all cards plugged in and it worked after I re-ran: sudo aticonfig --adapter=all -f --initiall Perhaps the higher voltage causes the mining speed to decrease (doesn't make sense, but neither does anything else that's happened with them). Since I only am running two until my risers get here, maybe I will just exchange the other two for vanilla vapor-x cards. If I can get those doing that they are supposed to, it would be worth the hassle for an extra ~150kh per card.
My limited understanding is that the cards have a feature called Powertune Boost which dynamically manages clockspeeds and voltages for maximum performance. That may be desirable in a gaming scenario where the rendering load changes from scene to scene, but not so desirable in a constant 100% load scenario. See: http://www.pcper.com/reviews/Graphics-Cards/AMD-Radeon-HD-7950-3GB-PowerTune-Boost-ReviewMy Sapphire 7950s have a little blue buttons on them that change the BIOSes and apparently also enable/disable Boost. I had the buttons enabled during the first few hours of mining/testing (thinking boost = more performance? yes please!) and noticed that the clock speeds jumped from 925/1400 to 850/1250 all the time. Just like the picture of Metro in the review above. (which is mislabeled with FPS instead of Mhz on the y-axis but you get the idea) Once I disabled the buttons and switched back to the regular non-boost BIOS, my clock speeds and voltages smoothed out and the hashing performance improved dramatically. As I’ve mentioned, I suppose the feature makes sense for games where you have rendering performance valleys and spikes that allow Boost to make the most out of the available TDP envelope, but it doesn’t make much sense under constant load. I think I had them disabled already, but just for kicks I enabled one of the buttons on one card .. it destroyed the hashrate and now cgminer reports it as "sick" whatever that means as an update, before i tried to push that blue button, i upgraded to 13.10 drivers and it got me about 5 more kh so I was at 525kh for each card... now i'm wrestling to get all 4 working again ... don't push that button! |

Taco can you take a look at my problem quoted below? Okay - need some help on this anomaly.
First rig - Sapphire 7970 standard edition with Vapor X, used settings suggested in Taco's thread - out of the box 650k/H per second.
Second rig - two (2x) Sapphire 7970 "GHZ Editions", used exact same settings in Taco's thread - out of the box - only about 350 k/H per second.
I have spent the last week in "newbie purgatory" so have been unable to discuss this issue. Finally on the second rig, I was able to get 500k/H per second/card by putting aggression back to 13, and overclocking the memory to 1680Mhz.
Can anyone tell me WHY do two of the same brand/manufacturer, same model, have such huge variance in performance?
Why would the two "Ghz editions" VASTLY under-perform the standard one?
Does anyone have any suggestions experience with a Sapphire "GHZ Edition" that could explain the variance? The standard one was plug and play @ 650k. The better ones have taken a week of tweaking to even reach 500k/H, and NONE of the recommended settings worked. I know it is not bad cards because they both perform the same - what is different about the "GHZ editions" that is hurting them so much, and made them so finicky? First rig is Q6600 65nm, 4GB DDR2, PCI-E 2.0, Win7 Pro 64, Sapphire 7970 - 650kH/s Second rig is 22nm Quad i5 Ivy Bridge, 8GB DDR3, PCI-E 3.0, Win7 Pro 64, 2 x Sapphire 7970 "GHZ Editions" - 990kH/s (both cards) I followed all instructions in this thread. The second rig would only do about 300 per card until I overclocked the RAM on both cards to 1700Mhz and dialed back aggression to 13. Any variance from that setting and I get LESS than 500kH per card. I would REALLY like to get the potential out of these supposedly "better" Sapphire 7970 Ghz editions. this might be the problem I am having then ... I have the vapor-x GHz edition because it was supposedly better and I am capped at 500kh (for each of my 4 cards) :/ I am running v12.10 drivers and 2.8 APP-SDK, my first thought is to uninstall 2.8 and install 2.7 because I read this was supposed to be better for mining. But I had already finished setting everything up and just wanted to go to bed if the standard cards are in fact quicker, then I am pretty pissed obviously since they would have saved me a few bucks each. I might exchange them since they are recent purchases if we think the GHz edition is the root cause as probably will be requested for everyone's use, the system is running linux and I have Sapphire Vapor-x GHz editions (4 of them). I am waiting on my riser cables to get all 4 running at once, but I have tested each and currently only mining on two. As stated, I was able to get them to max at 500kh with 975/1710 clocks, thread-concurrency 8192, I believe the voltages came stock at 1.25v .. I noticed the vanilla cards seemed to all have lower voltages, or is that my imagination? Perhaps the higher voltage causes the mining speed to decrease (doesn't make sense, but neither does anything else that's happened with them). Since I only am running two until my risers get here, maybe I will just exchange the other two for vanilla vapor-x cards. If I can get those doing that they are supposed to, it would be worth the hassle for an extra ~150kh per card. based on FullLife's post: So after reading through this whole thead, I thought I'd contribute my setup and config. Rig:i3-3225 Gigabyte G1.Sniper 3 mobo (in hindsight, I should have bought a different board, this one is overkill) 8GB DDR3 (4) Gigabyte 7970s link (in hindsight, I should have bought either vanilla 7970s or 7950s, these are not worth the extra $$) 1200W Coolermaster Silent Pro Gold ps (I can't say enough about this power supply, it's excellent) 250GB Samsung 840 SSD (2) WD hard drives (500GB, 2TB) Windows 7 Ultimate SP1 64-bit Setup:So I had all 4 cards running in my case, but with them being all crammed together, it was way too hot. So I pulled everything out and sat it on a rack. I have 2 of the cards plugged into the board, a 3rd card plugged in via 16x riser cable, but couldn't get the 4th card to work with another 16x riser cable. So, I ordered a 1x to 16x riser cable and hopefully this will solve my problem. In the meantime, I'm running 3 cards and getting pretty nice hashrates. These are my settings and results using cgminer 2.11.3 and AMD Catalyst 13.1 drivers: --intensity 13 -g 2 715/710 = ~1500Kh/s --intensity 13 -g 2 925/1000 = ~1950Kh/s --intensity 13 -g 2 1000/1206 = ~2100Kh/s --intensity 13 -g 2 1022/1244 = ~2150Kh/s Other settings: --thread-concurrency 8192 -w 256 I've literally spent most of a entire week playing around with settings and trying to find the sweet spot and I feel like I'm pretty much there. As you can see, I actually underclocked my cards to get these hashrates. Stock clocks are 1100 core/1500 memory. Unfortunately the default voltage is about 1.2 volts on my cards and its locked (@#&($$^(@&$!!), otherwise, I'd be able to save 100-150W easily by undervolting.  I'm seriously thinking about getting rid of these cards and getting 7950s or 7970s that don't have the voltage locked. Having the voltage locked is such a huge drawback, I'm just wasting too much power right now. I may try some of what he did because he has the gigabyte GHz edition cards and they seem to be hashing just fantastically. I'm not sure if the voltage is locked or not on mine, but it might be worth checking this out when I get home to try it. I can vouch for the fact that any intensity other than 13 on these GHz edition GPUs seems to be worthless. sorry for a long post, I just wanted to get my thoughts documented on this in case it helps me (and others) later edit: I forgot I set it up to connect remotely I set it to 1022/1244 (and played with other values around that) it seems that this was able to get me 20kh more, so I'm at 520k now... but I'm running drivers 12.10, maybe the key is 13.1 with these GHz cards, that will be my next thing to try, but I can't do it remotely. |

i have 4 7970s and for the life of me can't seem to get anywhere near what other say it can get... the highest I've gotten was 500kh/board if I'm lucky.
i've been using these settings to get 500 (cgminer):
--shaders 2048
-I 13 #any higher and it drops like a rock, any lower, slowly drops until around 10 where it only does around 50-70k
--thread-concurrency 8192 # i've been messing with this and anything but 8192 seems to drop it by about 5kh/s
--gpu-memclock 1700
--gpu-engine 970
I've messed with the clock speeds over and over but on my memclock, anything over 1700 seems to lock up after about 10-15 minutes, so I started messing with the engine to bring it into the .57-.6 ratio range and this is how I finally got it to go to 500kh.
i'm at a loss as to what to try next, if i bump the clocks up any more it will be unstable it seems.
I haven't messed with the voltage, but i wouldn't know what to do with the without destroying the cards. every guide i've looked at mentions that the voltage shouldn't have to be adjusted to get around 700k
anyone have any ideas what to try next?

litecoinpool.org is also down...
Take some time this weekend to set up your own p2pool node and mine from that. DDOS-resistant, no fees, more efficient. been wanting to look into this for awhile now, maybe this is my chance to get it working |
|
|
|

all my miners are now not connecting at all, they were still working when the site first went down, but no dice now
as a side question, will there ever be stratum support on kattare? if there already is, I couldn't find it so since i'm sitting around thinking about pools, I was wondering about this. The only one I've seen (with about 2 hours of looking mind you) is litecoinpool and they are closed to registrations.

what's the difference between your PLN cards and the other, more expensive ones? It was my understanding the PLN cards would still work with USD ATMs from looking at past posts in this thread.
What's the difference between the 0.36 BTC and 1 BTC cards?
