I am pretty sure that's roughly the same process as I'd have to use with my XFX card. You may have to mod the bios in order to up the overclock limits on the card... but from what I found in RBE, it recommended grabbing those settings from another bios, rather then just changing the limits (which it allows you to do) in case the card isn't recognized after that... So it may cause problems, but is probably reversible, unless you can find another bios to pull the heightened speed limits from. Have you tried unlocking afterburner and seeing what speeds you can achieve with that?

Have you gotten MSI Afterburner to unlock? I was unable to get it to let me push past the 840mhz that CCC gives me. Although, I finally tracked down the string you have to type in to the cfg file when you set the overclocking option to 1... I just have to find it again

OO00hh Thats a nice looking sig...  how'd you do that? If I may ask?

So as fast as a 6990 in OC mode... or not quite as fast as 2 6970's in crossfire.... Really, unless you have a space issue... Or too much money... 2 6970's are still better then this card... The lucid chip, in a bitmining context does absolutely nothing for you... Considering you can just launch extra miners, the lucid chip is only useful for making the two cards appear as one to games, and other big monolithic apps...

Save your money and get 6970s... unless you're really hard up for space... but i think you could almost build a small box and 2 6970s for less then this behemoth...

Well... So I found out some kind of disparaging news...

My XFX HD - 695X - ZNFC lacks the Bios switch to go from the backup protected to main unprotected bios for flashing purposes...

Further, there is some talk that it can be flashed, however one has to short a couple pins on the bios chip itself, as it is locked by default, and needs a hardware override to allow flashing. On top of that, it is undeterminable if after all that... that the shaders will even work if unlocked.

Sigh.

I like XFX... even though they are just Pine... but still, this is balls. Had I known this i wouldn't have bought from them, and would've gone asus, or sapphire even.

Ditto.. I am there as well and the payouts with no fees are great. So far the earnings have been great.

Awesome! and I think you all are doing wonderful work. Thank you!

It's iffy... many of the xfx ones can be.. but by modding the bios, not using the posted 6970.. however if they hardware fused the shaders, then no.

here's hoping.

Already there.. its complaining about a P/N mismatch between the bios I pulled off the card, flipped the unlock switch on, then went to flash back on to it... So Was just reading up in their forums before i forced it through atiwinflash.

Well downloading MSI Afterburner to see what I can get that way. And thinking about it... I am guessing that the flash running in th background of the websites I am on is probably cheating me of a few MH/s as flash accelerates on GPU... should close my browser when i leave. lol.

Bah MSI Afterburner will only give me up to 840 as well.. sigh... I unlocked the overclocking in the cfg file as well.. but I think I have to put a string in the line above it... Just misplaced the post that mentioned it. Perhaps flashing when i have more time.

Interesting, perhaps with the unlocked shaders the -v and -w128 actually increase performance, with normal shader count and core @ 840, it drops performance... hmm...

Short description:

Currently running GUIMiner v2011-06-09

Top scores seem to be running it standard,  no flags (which uses poclbm)   --device=0 --platform=0 --verbose


Every time i try and play around with Phoenix - no matter the settings:
-k phatk , VECTORS, FASTLOOP=false, BFI_INT, Workspace=XXXX, AGGRESSION=11 or 12 etc, etc...
I don't even get to the same level as just stock no option poclbm.


Is this normal???


All the suggestions i've gleaned from around the forums say Phoenix should be faster, and that the extra flags yield higher scores... and yet on my XFX Radeon 6950 1gb @ 840 core... Can't breach 310-320MH/s. and Pheonix with phatk gets me 275HM/s ish

Any ideas? My second 6950 is arriving shortly... so would like to eek out some extra without cranking the core clocks up.

Thanks

You do realize, and this is why i always recommend 6970's in pairs or trips, that a 6990 doesn't run the cores at full 6970 speeds.. so in essence you get something closer to crossfired 6950s... cause you're getting per core what i get on my 6950. and my 2 6950's cost me under $600...

However, if you need the density... then running dual 6990's in a mobo with only 2 PCIE slots is better.. but then heat, power, etc concerns come to rear their heads...

Either way, long story short. You'll have to OC the 6990 to get on par with 2 stock 6970s

Yeah... I suppose i could bump the aggression up... but it would have to beat Poc by a decent amount to be worth the loss of responsiveness on my system... hmmm... and you say to try and set fastloop off? Interesting... I need to find a good source for what exactly these parameters are.

I think I am already running that one..  isn't GUIMiner V2011-06-09 the latest?

And I believe with phoenix the flags are "-k phatk VECTORS BFI_INT" or something along those lines... I tried it and was hashing a bit worse then default Poc... So I'll have to dig into more settings, or try command line phoenix with phatk.

Just tried it again:

just -k phatk = 250MHash/s

add VECTORS = 254.5MHash/s ish

add BFI_INT =  251.x MHash/s

Stock Poc no flags = 305-314 MHash/s

In many cases if your overclock puts you in a stability position where your voltage selected isn't enough to stabilize the GPU, then you actually lose speed due to lack of stability. often you will find this occurs just before you start to induce crashing if you keep turningthe speed up w/o a change in voltage... Also, if voltage and speed are at a given setting, and 'should work' then you need to check heat and see if that is an issue. Heat as well will destabilize, and give an environment which would lower your scores as the card tries to cope.. (think VRM heat and lack of stable power, or chip heat - more rare)

Two other cases to consider - power throttling and memory speed throttling

a: power throttling occurs because 69xx cards can have there TDP limited, in this case the power is being artificially limited by more then just a voltage setting, this was introduced so that you wouldn't burn your card up in things like Furmark.. it simply limits the cards overall power draw at some level.. turn this up, and it may stabilize, and give expected results. 
(Can be found in CCC, there will be a setting labeled Power Control Settings with a slider between -20 and +20.... try adjusting that to the right... Be careful. Especially if for example its heat thats got you down, this won't help.)

b. memory bus speed throttling.. the 69xx cards have avery fast ddr5 memory bus, however it to can have issues when overclocked (less a concern with mining as the mem bus doesn't even need to be stock i know) however, when card starts to detect errors, it will actually slow the mem bus down effectively to bring it out of an error generating state, rather then passing errors on... So in away it will use speed to ECC...


Hope that helps you.

There's a bit more to it then that, Windows vista / 7 (they really are the same, just 7 is the vista core fixed.. think Win2k and xp... same core just modified) completely revamped how video cards and their memory were mapped within the system and accessed. So it creates  much more robust environment for multi GPU setups, winxp had to actually work the memory of those vid cards into its limit for ystem memory, etc. So consider a 32bit os based on an xp core, and you can see where 3 or 4 video cards would push its ability to properly manage all the memory / etc right out the door. Add to that base unsuitability for what your trying to make it do with the bad driver mojo that the previous poster mentioned, and then on top of that look at an application layer like OpenCL that wasn't even around when XP was in its prime... and you can see the multi-tiered threats to stability you are imposing on yourself. Even if you have an old copy of vista laying around, when patched up to current it'll run that hardware config better then XP. Vista/7 also handles multicored processors much better as well. If you can find it a 64bit version of vista / 7 would be better... you lose a lot of the limits imposed by the 32 bit os that way.. especially if you're talking 1gb 5830s x 4... thats 4gb of memory the OS is working with, plus system, plus swap...

I digress.... Linux if you don't need it for a windows box, or have a recent copy of the OS you trust.  else 7 or vista.

Just figured I'd add it again.. but when I put in the -v, I drop by about 12-15% I go from 314ish to 274 ish... hmm.. I'll keep digging. perhaps its the miner I am using.

I don't have experience with other pools.. but this one seems to be paying out higher then I expected... even accounting for that one time bonus Now I just have to bring more gear online for the pool.

Which miner and kernel do you use? what's your hash rate?

thx
