Other / CPU/GPU Bitcoin mining hardware / Re: 7870 mining speed, over 430 Mhash/s ?!

Hello, i just got my 7870 Sapphire 1 Ghz Eddition today and overclocked it to 1.1 Ghz (i think it could easy do 1.2 ghz or even 1.3 ghz)
im using 12.3 drivers and 2.6 SDK (for some reason i have no 100% cpu bug, (i use an 5850 and the new 7870).
and right now with " -v -w256 -f0 " in guiminer i get 403 Mhash, and my p2p is showing the increase in speed too!
anyone else can confirm this performance?
Why are you using Guiminer? Use DiabloMiner or cgminer instead. DiabloMiner has a kernel optimized for GCN. Anyhow, by my calculations, a 7870/1ghz should get about 375, at 1.1ghz about 412. i have not much experience with other miners, can i set different settings for each card? since im using this PC as main pc. |

Sorry, i cant see the power Draw on any tool, but i got an kill-a-watt at the wall, i could turn of the gpu using its feature zero-power core, and then see the difference, hope that this will be enough good enough.
EDIT:
450 Watt - Total System Power Draw with 7870 Mining at 430 mhash/s
273 Watt - Total System Power Draw with 7870 in ZeroCore Power sleep
that would make 177 Watts for the 7870 alone!

ive just increased my gpu another 80 mhz , from 1100 mhz (403 mhash) to 1180 mhz (430 mhash), this is all without an change in voltage. I think as headless miner and voltage tweak and higher OC ( i saw some runing this card on 1258 mhz with more voltage) it should do more then 450 mhash/s. EDIT : My ASIC Quality is 78.8% (a new GPU-Z feature) It represents the arbitrary number Nvidia or ATI assign a die based on its location and performance figure they are trying to target. Just like it was said before a lower number should have higher leakage, but may also mean a closer to the edge die cut. If everything else were equal a number such as 85% should yield a balance between leakage so you can throw more voltage at it and non faulty transistors from die defects. here is an pic i took:  |

does that mean i can use the newest driver and only have to change the SDK's to get the "bug fix"?
im using my main pc, for games and mining, so i need new drivers for games like BF3 and such.
could you make a step by step guide? cuz its kinda confusing, i havend done much with sdk yet, and been using gui miners since i started mining.
I went through this last night after my 6870x2 and Ubuntu refusing to cooperate. I'm in a similar boat and was running catalyst 12.1. I did a complete driver removal and rebooted. I installed in this order: 11.12 catalyst SDK2.1 CGMiner 2.3.1 Sapphire Trixx For some odd reason I was having major issues the first time I tried to install SDK2.1. I don't know why, but it just didn't want to work with GUIMiner. 11.12 has it's own SDK package that you can see if you select to custom install. That SDK and SDK2.1 install in different directories as mentioned above. There are no CPU bugs and I am not using dummy plugs. My 5870 at 975/170 1.100V hashes steady at 440. My two 4x5870 linux rigs that run 11.6 and SDK2.4 hash slightly lower around 425-430, but I believe there is another issue. The 6870x2 and 6870 also in the system are proving to be a pain in the ass, but at least it is working. So, which SDK is being used? the one which comes with the 11.12 driver or the 2.1? Edit: i just now installed the new SDK 2.6 and my 7870 and 5850 are working without 100 % cpu bug! |

good to hear that about the translator.
about starcraft, the cheapest i can find is about 40€, about 55$ i guess, found these using google shopping.
But still expensive :x
i was hoping that you could find a cheap source xD
What versions will it be anyways? Asia? US? EU?

whenever i open your shop, google asks me if i want to translate the page (which i dont want) its something Spanish related, but im from Germany though.
I dont use either google addons or chrome, i use Firefox.
just wanted to tell you that, is getting abit on my nervs.
Everything else looks good, im just surprised that minecraft is that expensive. (not especially on your side, but in general)
Any chances for Starcraft II ?
