I still have an overclocked HD7950 (variant with the HD7970 PCB) , I flashed an R9 280 BIOS on it. It have a mild OC with 1,1 Ghz core and slighly OCed memory . It still running fine despite being almost 6 years old. It runs many games ok for [email protected] fps even this year, just tweaking down some options depending on the game. For some demanding new games it show some limitations but It is still working and I will maintain it while it works and the GPU prices stay so inflated. To the day it is the GPU served me better of all the GPUs I owned.

I have some questions about this legendary bang for the buck card:
- There is any advantadge on running a R9 280 BIOS instead of an original HD7950 one?
- Should I replace the stock TIM? It is Arctic MX-4 compound fine for it ?.
- There is any aesthetically fine way for a fan mod? Temps wise stock 75mm fans are fine, but they're too noisy at high RPM.

Greetings.

I'm selling my old 7950's on ebay... both have R9 280 bios's on them, the only advantage to that is seeming memory timing related... a minor, but consistent improvement over the 7950 bios.... a link if anyone is interested: https://www.ebay.com/itm/273624013589 that is only for one of them... the other is in my items for sale... I don't know if this is against the "rules" to put this here, but I figure that given the disabled nature of the site now it's be ok to put this here instead of the normal places

Intel who?

If there are any 7990/7970/7950 owners still lurking here, the OCN BOINC team is currently running the [email protected] project as our GPU Project of the Month for January. The MilkyWay project utilizes fp64 calculations, so these cards are still very relevant for the work that this project is doing. Link to the [email protected] homepage: https://milkyway.cs.rpi.edu/milkyway//index.php

If you want to help out the OCN team head on over to the BOINC section and check it out. https://www.overclock.net/forum/365-...et-boinc-team/

hi i have a xfx core edition (single fan) variant of the card and was wondering if the bios hacks for it would work cause the voltage limit is locked. it can overclock so so but i think theres more potential in her and also i have it modded from its original single fan design to basically a double d version using a different gpu's bigger cooler and it doesnt get above 65 or so (70 if it gets hot in room) while gaming

highest validated but not stable https://valid.x86.fr/3lmf5s

Got a picture of your card?

Does GPU-Z report VRM currents and actual voltages, or just speeds and VID?

The uP1608 voltage controller found on a lot of xfx 7950 lacks monitoring and proper voltage adjustment. BIOS editing is difficult and no other BIOS-files works.
Hopefully you have the Chil controller.


Reading this thread made me wanna squeeze some more performance out of the old POS XFX card. Non reference 7950 with unsupported vreg.

Just mounted a Hydro H105 Extreme and im aiming for 1200 Mhz core.
Had to make a spacer since the shim is a lot higher than the die. Had some silver lying around that only needed a few minutes with a file. Not pretty, but works like a charm.
Im using liquid metal, so I was planning on adding a layer of insulation .. But couldnt find the liquid tape, so I just grabbed a spray can. Does metallic paint conduct electricity?
Only one way to find out.
Everything flat and sanded down with 2000 grit. Applying liquid metal is a walk in the park after removing the oxide layer and possibly some turtle wax. Some people ....
