Can't increase voltage - Gigabyte 7970 WindForce 3X GV-R797OC-3GD - Page 15

post #141 of 205
Just got my card today and flashed the GHZ bios. Everything worked. Now just hoping that soon someone will be able to get a BIOS where we can have fully unlocked voltage.

Afterwards it crashed during gameplay, so I wonder:

Is there a reason that after flashing Tahiti.rom my voltage would remain stock but my clocks go to 1100/1500 as planned? What can I do to get 1.256 voltage as well, as it is surely necessary for the OC caused by the flash. Would re-installing the drivers somehow help this? Am curious. smile.gif

EDIT: Actually my voltage is even lower than I remembered - it stays at 0.850V, even after flashing the BIOS as described above. Any ideas?

Got a 2.1 rev card a few days ago, was doing some research on it before and found the bios flash from the ghz edition from here, so just posting my results. Got my card on Wednesday, I already prepared a boot stick with the tahiti rom and atiflash, didn't want to bother with it without the flash and flashed it right away. Used the command "atiflash -p 0 tahiti.rom -fa -fm -fp -fs" and everything was fine.

When testing out Crysis 2 and Far Cry 3 the games crashed with the amd display driver stopped working message. Tried 13. 1, 13.3 Beta 3. 12.11 using the ati removal tool to remove the previous drivers without any success. Was having issues with the OpenCL when trying GPU-Z, and it didn't go away with any of the drivers which I didn't have with my 6950. Tried overclocking it but it stayed stable in windows but the games would crash and amd driver stopped working message would pop up. So i decided to downclock the card to stock levels and all was stable and well, then increase by 10mhz at a time, 1080 mhz was all it was stable at, any higher the display driver would stop working, so I ended up with a poor overclocking card.

Returned it on friday and got another one hoping for some luck and no issues, OpenCL working perfectly with 13.3 Beta3 and stable in games at 1100/1500. Used same method to flash. stable at 1120/ 1500, satisfied with the card now that its basically a ghz edition and can overclock decently. Might try going for 1200 when i get the rest of my new rig. So if your card crashes in games, i suspect your chips limit is lower then 1100 so i suggest you return it and get another one. Every chip overclocks differently, you can only hope you get the good one.

Dear EQBoss,

I think you are exactly right! smile.gif I flashed my Rev 2.1 GV-R797OC-3GD to the GHZ ROM mentioned throughout this thread. It listed 1100/1500, but would crash during game play. I tried a different ROM, and it also would crash during game play. I went back to the stock BIOS, F72, and overclocked to 1050/1375 (lol)... so a minor 50 mhz. This worked out OK, no crashes and that's what I'm using now. I raised it to 1060/1375 and it crashed during game play. I guess my limit is 1050! O_O So, despite all the random efforts of flashing this and that ROM... I would say that quite simply my card is maxed out at 1050 and can do no further in any iteration.

Out of curiosity... how are you guys managing to return your cards? Haha... I mean, I have 3 year warranty on this one, but I did not buy from a major outlet (newegg/Amazon/etc.) but only from a small store. What's your justification in returning it? lol... since overclocking is an out-of-warranty activity anyway, no? Anyways, not bothered but am curious how it works. O_O

Best,
Sens

I'm simply not satisfied with the card, was getting errors when playing games so I returned it. I bought it from Memory Express here in Canada so i just returned for those reasons without issues and they gave me a new one. Ofc I flashed back the stock bios lol. On stock bios you're not gonna get past 1050, don't even bother trying. You should test the rom with the ghz bios and drop the clocks to 1000mhz and 1375mhz and go up from there to see when the errors start, thats how far your card can go with the ghz bios. The ghz bios has higher voltage so higher possible OC. How high depends on your chip, each one is different.

Well I flashed my card easily enough following the instructions but it is not liking the 1100/1500 settings and will run for a while and then crash in Valley benchmark or fullscreen furmark. I guess my card is not a good clocker. Will try and fiddle around with it some more tomorrow, if no joy then exchange it I guess.

man i just got this for replacement of my faulty msi 7950, stock core was at 1ghz, increased to 1,1ghz, crysis 3 crashed sometimes.. guild wars 2 was also crashing at 1,1ghz@1.25V so i dropped it to 1050mhz, so max oc on core is 50mhz.. im disappointed ;(. Memorys are atm 1350 from stock 1250, over 1400mhz on memory would crash gw2 sometimes, fuu.. card is cool and very silent tho

edit: o nvm thread is about 7970's, iv got 7950.

Hey guys need some help. Whenever I try to extract the atiflash.exe file to the usb dos boot drive I get:

Error 0x0004005:Unspecified error
atiflash
Type:application
Date modified:3/6/2012 2:34 PM
Size:1.80mb

I trid just dragging the whole folder to the boot drive and that works but when I get into dos and put in the command to flash the bios I get the "bad command or filename:atiflash" message which means the file is not available for use.... Any ideas?

I have the gigabyte 7970 windforce x3

Edit:
Looking in events log I get this error message. Could it be because I'm running the 13.3 beta 3 catalyst driver?

Well I just used the ati winflash utility and that worked. Heart was pumping but ran 3dmark 11 to test and it went up from 13400 3dmark score to 14100! So a nice little boost. This is crossfire of course. Haven't tried moving up more on the frequency but this is fine for now, I don't think you'll get much more real world performance in games. Here is the guide for ati winflash in case people are having issues with atiflash. Nice thing is you can do it from your desktop using the cmd.exe windows file.

Hi all guys!

Same here, i'm using the F62 Bios (also used the tahiti.rom bios but is the same so i prefer the F62) on 1100/1500 can't go much higher. But i'm not very satisfied because sometimes it crashes and on older games such L4D the core clock sets itself to 501Mhz and fater 10 seconds i get a black screen and looped sound frown.gif

I think we can just hope that Gigabyte releases an unlocked BIOS... but I think this will never happen :\

yeah after running it on the ghz overclock 1100/1500 for awhile now I was getting black screen freezes in crysis 3 that required a hard reset. Anyone else have this issue?

So what I decided to do was to set it back to default clocks and inch it up 15 mhz at a time. So far I'm at 1075 core and 100 percent stable. I think the memory overclock is the issue here, I don't think the gigabyte windforce x3's like the memory upped at all so I'm keeping this at default until I get the max core frequency. Not sure if that's because of overheating, guess there isn't any diodes on the memory to read temp so not sure if that's why it is black screening.

You will get more performance from a higher core frequency than the memory though so after I get the max core frequency, I will start inching memory up 25 mhz at a time. But it may have to be left at 1375.
