FVIRF к сожалению я не нашел ссылку ,да а тебе то зачем у тебя воздух?

Помню, ты мучался с багом при установленной водянке, тебе пришлось поднимать частоты в 2д.
Так вот, по-моему, я нашел выход из этой проблемы.
Называется это колд баг, проявляется при 35С и ниже, пофиксенный в новой версии биоса сапфира, вычитал на гуру.
Дело осталось за малым, найти этот биос, на тече только один, для мастер чипа http://techpowerup.com/vgabios/index.ph ... &memSize=0 , а вот второй где найти, х.з.?
Если найдешь, отпишись.
Чел на гуру визжал от радости, показывая какие-то нереальные приросты производительности на новом биосе, найти эту ветку не могу, т.к. очь много перелопатил инфы .

Коллеги, помогайте, плз, нужен сапфировский ОС биос от апреля с.г.

I have a Gigabyte 5970, and am now using an EK 5970 full cover waterblock. As a side note, this 5970 required an extra layer of thermal pad on the CPL-2-50 chip in order to be in full contact with the waterblock. I was able to get to 24/7 stable 1000/1200 1.275v (GPU) 1.1v (memory).

Unfortunately, I was suffering from the cold-bug, where video would hard lock up (in games like BC2 that use both GPUs) if the temperatures hadn't yet raised beyond about 35C. This cold bug with water cooling is fairly well documented, but not yet fully understood. The problem appears related *only* to the second GPU on the 5970. I tried various versions of BIOS images, including the stock BIOS as well as the powercolor 5970 LCS bios, and these didn't help -- cold-bug in all cases.

One post suggested raising the 2d clocks for all GPUs with a CCC profile, though this comes at the expense of significantly greater power consumption (about 50W from the wall at idle).

I've come up with an approach that seems to eliminate the cold-bug, with a very small increase in idle power consumption.

Basically, what you want to do is change the 2d clocks *only* for for the secondary GPU. I used radeon BIOS editor on the secondary GPU bios image, and changed the 2d clocks from 157/300 to 400/900 (and then changed GPU register 0x15 to 1). You don't need to change the 2d clocks in the primary GPU bios image. I am going to experiment with lower clock values later.

One thing that is odd about the 5970 vs. the 5870 is the way the memory voltages are setup in the BIOS, and also observed with GPU-z and other software. The 5970 uses 1.1v by default for all memory clocks (300, 500, 900, 1000, ...). Whereas the 5870 uses different memory voltages for different clock settings. For example, an XFX factory overclocked 5870 uses these:

300mhz - 0.95v
900mhz - 1.00v
1200mhz - 1.1v
1300mhz - 1.15v

By default, it looks like only VTT register 0x15 is used by the 5970. If you set this to say 1.15 with a custom BIOS, this voltage is used for all memory clock speeds.

I wonder if this is related to the 2d stability problems that impact some 5970s. Perhaps 300mhz @ 1.1v is unstable (on the 5970), whereas 300mhz @ 0.95v would have been stable. I'm going to experiment later to see if I can influence the memory voltage for different frequency settings (perhaps through a custom CCC profile).

For 5970 Crossfire Eyefinity users: Cannot believe it, but now it works!
After half a year of trials without any success!

Tried Crysis, STO and Metro2033 - all of them supersmooth.

Metro2033 always above 130FPS at 6008x1080 !!!

If you all are unhappy with these drivers - I am sooo happy now !!

FYI: Additionally to this driver I found a new BIOS at Sapphire (release April) for the 5970 and flashed both cards Master and Slave!
This solved the Cold Bug on Watercooling.

Now this driver made 5970 Crossfinity now possible!!!

So for all guys, why tried Crossfinity on 5970's: There is light on the horizon!

Вспомни где ты вычитал про этот биос!

For 725/1000MHz HD5970 standard version ONLY P/N:102-C00001-00-AT Please see atatched test BIOS for Hemlock . we will update BIOS with altocal off after we finish the BIOS qual, so attached test BIOS is not MP bios, only for you to test it on Hemlock Hynix AFR 3D failing cards ( which has 1.26 u code already and still grey screen when run 3D app) SC00001M.ACL is for master SC00001S.ACL is for slave.

Благодаря камрадам с ixbt, за что им отдельная благодарность, надыбал биос для не разогнанной версии Сапфира.
