"HD7970 & HD7950 Results Thread - Torture Your Card, Post It Here!"

[flopper]

i got offered a 7970 that can do 1300 core at 1.22v on water and up to 1380 core max

is that a golden card?

pretty much yea.

[Dahaka]

Guys, actually i have the Swiftech MCW80 and i want to upgrade my "oldie" GTX 560 Ti, i don't know yet if buy a 7950 or 7970. Now the doubt is if i need a upgrade kit for this waterblock to mount in one of those cards.

Regards.

[OCAUfedexpress]

pretty much yea.

sweet thanks mate

Anyone have the gigabyte 7970 windforce, I can only get it to 1075/1600 with stock volts. The problem is there is no way I can get 2.2.3 msi afterburner to change the voltage.
When I change the eula stuff all the sliders including memory and core can't be changed nor do they read the card.
Trixx will only allow me to downclock the voltage, same goes for the gigabyte overclock software.

Hey mate, I bought a 7970 on release and I think it maxed out at around 1260 or there abouts, so yes that is a good one.

Guys, have you unlocked vgpu on these without hard mods yet? Im keen to revisit these and push for a better PB.

I disabled ulps in registry and I set these settings in afterburner http://imgur.com/a/D6CXG

but no way can I get afterburner to overclock voltage or increase limits.

I'll probably be chiming in here in the near future, I'm almost fully decided on a MSI TwinFrozr. AMD seem to of pulled their thumb out their arses and sorted their drivers out so I'm willing to give them a go again.

ULPS wont do much for you. You wont be able to overclock it no matter what since AMD removed atipdlxx.dll and atipdl64.dll from their drivers few releases back. You'll have to add those manually or use modified drivers that already include those.

[Ket]

Just because its something that isn't done nowhere near enough IMO, driver comparison: Clicky

Thanks for the reply, I figured ULPS won't do much, so I re-enabled ULPS in registry. I've actually copied both those dll's to the syswow64 folder and the msi afterburner folder but that didn't work either.
If you could check that I got the right file version that would be great, I've included the details of the .dll's here:

I spent 2 days trying to get this to work but atm the weather is very warm so I have been out mostly. Do you think it's possible Gigabyte removed the ability to overclock this card in the latest version?

[Ket]

I don't see why Gigabyte would do that, OCing is pretty much the main selling point of that card. Have you tried a slightly older version of the software to rule out a buggy release?

[Ket]

My MSI TwinFrozr 7950 arrived today, just installed it with 12.7 beta drivers. Time to see how this card OCs... and eventually I'll get into vBIOS modding the card. ASIC quality is 75%, which would seem to be very good based on other peoples 7950 ASIC quality which seems to be between 61-71%

Well gigabyte are not supportive at all of overclocking outside of the standard overdrive. They have software which doesn't work for this card and they won't be releasing a bios with higher voltage for this card. They have another oc model with 5 fans, that is supported iirc.

Basically I've tried at least 3 different versions of afterburner with 12.7/12.8 drivers, I also tried trixx. I installed 12.6 beta and tried afterburner and trixx again, no joy.

I hope it's a good one, tell us how the far you can get it to go with some extra volts.
I'll probably send back this gigabyte 7970 1075/1550 and get a 7950 I can volt, I can't justify keeping it when a 7950 @1150 will beat it and I'll save some money

[Ket]

Thats very gay of Gigabyte, I wouldn't keep the card either or I'd at least try flashing a few different manufacturers vBIOSes onto it first to save the hassle of sending it back. Early testing of my MSI 7950 suggests it is a good OCer. Haven't tested memory yet but I easily maxed out @ 1100MHz with a measly 1.1v. On stock volts of 1.03v I comfortably hit 1010MHz. I'm going to try the /xlc trick with afterburner and see how much further I can go. I'm pretty surprised nobody has made a vBIOS editor for these cards yet.

ED - WTF AMD.. /xlc doesn't work anymore from what I can tell.. limits remain the same in Overdrive as do they in afterburner.

I actually did try flash some bioses, one caused a problem in windows so I had to force flash the original in dos. I do really like the card, it has an awesome cooler, so awesome I feel obliged to overclock it and it is a hassle to send it back.
I don't understand why your voltage is soo low, I assumed the 7950 core was pretty much the same as the 7970 core, either way 1100 is incredible if it's only 1.1v. Mine is stock 1.17v
and from what I read up to 1.25v seems totally reasonable if I could do taht

From what I understand making a bios for these cards is next to impossible, on laptop models it is possible but on desktop they have some sort of encryption that no one has found a way around iirc
For me the /xlc command worked fine in 12.7 and 12.8 but I already had limits of 1200/1650 so getting 1800/2475 made no difference to me.

I just followed this thread: http://forums.overclockers.co.uk/sho...php?t=18431335
I can't remember if I actually needed those files but I have them installed anyway.

[Ket]

No encryption is impossible to get around, I don't understand why AMD are so friggin anal about having stable clocks flashed directly to the card. Crap like that is what makes me want to send this 7950 back and buy a GTX670. Check out my thread HERE, theres some stuff in there you will probably find useful to coax that weinerforce into OCing. The second post especially will probably be useful to you.

Update: I sent the 7970 gigabyte windforce card back yesterday. I spend an incredible amount of time trying to unlock this card, just before it went back I even tried to install 12.1 beta and 12.1 whql, they wouldn't even recognise the card, ie catalyst didn't even come up.
I reinstalled 12.8 and returned the card, I put my 6950 with unlocked shaders in, didn't bother reinstalling drivers, I fired up 2.2.2 afterburner simply because it was the last afterburner edition I tired to unlock with, iirc it asked me to reboot my computer first, I rebooted and fired up afterburner again, it opened up with the ability to change voltage.
I used ab to unlock the overdrive limits with worked fine as it did with the 7970. Changing the voltage with ab or trixx doesn't change to voltage on the desktop gadget by Orbmu2k but Gpu-z confirms the change and works even after I close either program and even after I reboot, so I'm guessing it does it in registry.

I still don't know why the 7970 windforce wouldn't let me change the voltage, but I should have just sent it back earlier, I spent far too much time trying to get it too unlock. It was fully stable @1075/1550 with 1.17v My ambient here was 30 degrees and my case is more designed for sound dampening than airflow but this card never went over 66 degrees and I could never hear it, so from that aspect it was the best card I ever had.

new 7970 DC2 non TOP

Unlock bios
1300MHz 1.291V

1250Mhz 1.226V

[Ket]

Ew that factory TIM application is horrible. I bet you are getting a good 5c better temps after redoing that.

[Maxforces]

already been done
CFIII
- 2C>3C only

[Ket]

2-3C lower temps is still better than nothing, a improvement is a improvement

[Gaul]

anyone have HIS 7970 icq X2 Turbo ?
i need that bios

http://www.hisdigital.com/un/product2-692.shtml

[Gorki]

Anyone had any luck editing bios and reflashing it back? I'm kinda skeptical on this on, I had to ask. I was hoping you could edi card speed and voltage and reflash it.

[Ket]

There is a tool in development. Its early days for it though currently. You can find out about it HERE

[Gorki]

Yes I bumped on that thread Ket but I'm still waiting for confirmation , I hope it would work fine on desktop GPUs thus it would be nice to have direct download link to this tool.
