79?? Identify - Page 4

post #31 of 35
Thread Starter 
Ok thanks for all the info and Im learning quite abit here about a card I knew nothing about. If it wasnt for registering on the club thread and posting my gpu-z I wouldnt have dug into this card. I was blaming my lack of performance gain when upgrading from my 560ti on my older cpu which turned out to not be the only problem.

When I get time at home flashing will be my next project. Question though what exaclty does it mean if its a reference or non-reference. Also I was looking at bios on techup and how do I tell if it is reference?

Reference means it's using the PCB design AMD built for the card. Non-reference is when the manufacturer makes it's own PCB for the card. It remains the same card, but the BIOS will be different.

I'll find a reference one for ya.

Found it:
http://www.techpowerup.com/vgabios/126157/his-hd7950-3072-120706.html

That's a reference 925Mhz boost BIOS.

That's not a reference BIOS, that's a BOOST BIOS. Reference BIOS used 800 MHz GPU and 1250 MHz memory.

Original BIOS version is :

015.013.000.010.000705

But there are many OEM-modded version of this BIOS on our database.

That said, BOOST BIOSes should work on reference cards just fine, although there may be some issues(BOOST BIOS is typically 1.25V, original reference 0.900V)

So ive tried two bios. A 7950 reference 800/1250 and a 7970 reference 925/1350. only two i found that work. No change in my shaders. Still at 1562. I ran 3dmark11 with the 925/1350 and I get the same results at my 925 bios 2. the only difference I notice in this bios that amd overdrives sliders go to 2000/2500. Not gonna do that since at 925/1350 on 3dsmark11 my temps already reached 80.

My battlefield 3 frames are all over the board, jumping around from 40-80. I run high with 1680x1050.
