Because every chip is different, one can run hotter and yet run at higher clocks. Just look at the difference between the C0 and D0 I7 920.
Hey guys. One question. I have an 5770 Vapor-X, I save the bios with GPU-Z, imported in Radeon Bios Editor 1.22 and modified some settings for max occ. using clock tuning wizard (1050 GPU/ 1300 RAM/ 1.272 voltage). I also used, in "Additional features" - "Method 2 - No hash" for upper limit GPU 1200Mhz\ Upper limit RAM 1500Mhz. Please tell me if is possible to flash the bios using the current settings. I heard and also read in here that there might be some problems with the RBE and to kill my card. Thank you in advance for advices.
this will not work you wont be able to load any catalyst driver for the card because you have moved the upper limit for ccc overdrive your self then the driver say it is a no go
OK, so if I leave unaltered the upper limits in "Additional features", and only modify the voltage and frequency for the GPU/RAM, should I be ok? :confused:Quote:

I tried this bios on a Club3D 5770 V2. Stock volts 950-1350 possible. But voltage adjustment with afterburner is not working. I used a multimeter but its still stock 1.14-1.16v load while i did set 1.2v.
Anyone here that has succes with afterburner and a V2 ?
try asus smart doctorQuote:

Hey, i bought two HIS 5770's but these seems to be with HIS's own PCB and ofcourse, these are CCC-limited and Asus bios wont work with these.
If i try to oc with MSI Afterburner (EnableUnofficialOverclocking =1) my system freezes if i raise gpu clocks. So that wont work either.
AMD GPU Clock Tool wont even recognise my cards. This is very disappointing cause i can hit 960MHz with stock volts which are also bigger than
normally, stock volt for these are 1.2v. Any ideas how to achieve more clocks to these? And these have only one Crossfire connecter also!;)

snoro, if you have this card you might have same problem as i have, that's with different pcb also..

no i have a v1 xfx card.
edit, did a bit more searching and found that you can enable unofficial overclocking in msi afterburner that go past the bios limit. I am now running at 1ghz core 1.35 ghz memory at 1.25v with only 2c more of max temp at full load.
You just have to open the config file of arterburner and change the unofficial overclocking value from 0 to 1 and you are good. Dont need to flash the bios.
the only drawback is you lose powerplay and that mean it never get into its idle mode so if you bought it for the power saving, the afterburner unofficial trick is not a good idea for you.
No, that's not working with my cards. Instant freeze when i try to overclock with unofficial enabled.
maybe you try a bit too much ? i was able to get 1050 core and 1400 memory with no problem at 1.25v with no error in furmark stability test and temp never higher than 60c. pvhk and bhavy could help you a bit more for crossfire overclocking. Have you tried asus smart doctor ? it could be more easy with that.
No matter how much i oc with Afterburner when unofficial overclocking is enabled, it freezes system anyway, even when downclocking.
With unofficial disabled i can oc core's to 960 (limit) without problem.
use the amdgputool
AMD Gpu Clock Toop didnt work either, but i solved my problem! Cause of that was 9.12 Hotfix drivers and ULPS.
When i chanced "EnableULPS" register from "1" to "0" with regedit and rebooted, now i can overclock these cards over the CCC-limits
with MSI Afterburner!:) Second cards fancontrol didnt work either, but no it does! Perhaps this could help someone else also!
That's with Windows 7. Good luck guys!
So, i got overclocked these cards but when i tested these with 1.27v, another cards temps raised 80c under unigine heaven!!
So i desided to reseat coolers and added new pastes for both, also inserted heatsinks to mems.
Temps dropped more than 25c!!! Here some results with 1.3v/980MHz! Unigine really stresses gpu's to their limit!

It was GPU2 which had over 80c temps, and reason was cause HIS was inserted way too much thermalpaste!
Cooler didnt even touch the chip it self. So this "modding" was absolutely worth it!:)
Here pics from my cards with memsinks.

good to know since i might be thinking of getting a asus v1 card and do crossfire in maybe 1 or 2 month when i have finished paying everything on credit card that i bought for the computer or christmas.
I just ordered 2 sapphire 5770 cards and 2 EK fullcoverblocks to keep them cool. :)
I'd like to know if i need to flash this bios on the Sapphire cards (V1 cooler) or is the Sapphire bios good enough for 1200 CCC limit?
just change the enableunofficialoverclocking value from 0 to 1 and get the 9.12 hot fix for crossfire and you should be good
Thanks, just changed the value already and am now at 1200 limit for my current 4870.
Can't wait for the 5770's. :)

heres a good guide for flashing using atiflash
edit: apparently not me haha :p
so im having trouble flashing my 5770
so i fallowed the above link directions ( http://www.techpowerup.com/forums/sh...ad.php?t=57750 ) formatted the usb stick and put the atiflash 3.79, and asusunlockedbios.bin on it.

then i boot from sub stick and at the command i type
c>atiflash -p 0 asusunlockedbios.bin
http://farm3.static.flickr.com/2694/...c9b38677e9.jpg
what am i doing wrong?
You have to force the flash with this command
-f -p 0 asusunlockedbios.bin
