Ln2 cooled, was keeping it between -120° & -130° with voltage at 1.568 (vdroop to 1.468). Using stock voltage with cold it was maxing core at 1350 at 1.3V, same card maxed at 1237 1.3V on water. They like colder.

What does the ULPS actually do, disabling disables the ultra low power state I'm guessing? Haven't played with that one.

SonDa5, the different shader count on the card might not like the new bios that wants to use those extra shaders.

Not sure why it is not working.


Below is the BIOS that I'm looking for.

A more realistic test aimed to the average overclocker to see Core and Mem Gains, decided to use Crysis 2 with adrenaline tool as it more easy to understand and still a high demanding game after the dx11 patch...Also it is a more fps raw game, so it will do fine.

So specs...

2500K @ 4.5GHz
16GB of ram @ 1333MHz
the rest is the difference between clocks on the 7970..

I test 4 combinations of core clocks, memory was 1600MHz in all of the tests, choose this one as default for a reason (not everybody gets 1800/1900mhz on their 7970 and 1600MHz seems more common between all the cards) Also test 925/1000/1100/1200 for a reason too...

Here are the core clocks results
coregains.png

Here are the memory results, in this test 1200MHz on the core
mmgt.png

Images are self explanatory i guess....

In another words... (rounded all the numbers to lower the margin -/+ error)

925 @ 1000: +%5
925 @ 1100: +%11
925 @ 1200: +%16

Note: Dont matter if your card is factory oced, the regular 7970 is 925/1375MHz as reference...

For the guru guru XD
GHOST EDIT (fixed)
925/1375 @ 1200/1800: +%25

The best gains taking the whole different clocks scenarios and average core/mem clocks readed on here that are ((EASY)) achievable (even without touching the card volts) are 1100/1600 in this case.... Im not saying this is the average top of this cards.....

Hope this help a few out there that are not into the extreme overclocking and just want to suck the best they can "safely" of their hardware...

Thread Starter 

Hi guys/gals, 

There's a small update to Atiman Uinstaller 7.0.2:

 

* AMD Install Manager for AMD chipset mobo version updated.
* Fix minor bug in the Install Manager when uninstalling AMD mobo.
* Removed the express tab in the process above Install Manager.
* Removed the possibility to question in the last "gray" window.

 

The DL-link and version number are the same and anyone that downloaded the previous 7.0.2 is advised to update.

Hi All!

Quick question for the club members:

This is a really long thread, and I am unsure if there is an OC guide somewhere in here. I am looking to find out which 7970s can have their voltage controlled VIA software, and which software can do it. I am a fan of MSI AB, but I heard that you might need to alter a file to unlock voltage control? Also will AB work with all Bios' from all manufacturers? Will any of the cards need a BIOS flash? It would be nice if we had a repository of guides and tweaks necessary for unlocking the 7970s to their full potential.

Any help and/or links are greatly appreciated.

Thanks in advance!

To those thinking about the Sapphire OC or MSI Lightning... It seems the Sapphire is a formidable foe if you dont mind the potential for coil whine (Which I do not get unless I am above 85% Utilization) My significant other, I played with his Lightning today and could only reach 1250 // 1900 stable without some serious temp. problems in Kombuster. (I am talking above 90c here) while in the secondary Bios position. Then again Im not sure If I got a golden card and he has a under achieving Lightning, since we all have different experiences... But I was able to hit 1400// 1575 (Lowered bandwidth to keep VRMs a little happier) I will furmark it later when I am awake, but... I have had no driver crashes, VDDC Resets, etc while gaming. 1.3V I will post results for both in morning (EST)
