[Official] AMD Radeon HD 7950/7970/7990 Owners Thread - Page 3550

post #35491 of 38704
Guys, buddy of mine bought a refurb HD7970 Lightning from a local reseller and even though the card works, it will only show 1792 shaders in GPU-Z.

So, I told him to flash a original Lightning BIOS on it.

We flashed a Lightning BIOS (Stock, 1070/1400 clocks) and a Lightning BE BIOS on the second switch (1150/1500 clocks) and to out suprise it still has just 1792 shaders.

So, what can we make of this? It kinda seems to under perform in 3dmark as well by a couple of 100 points..

You got a 7950 with a lightning twin frozr. Not sure how when the twin is a custom size PCB.

The PCB is clearly a legit 7970 Lightning PCB as it has the reactor, measuring points, MSI Lightning branding at the PCI-E slot and so forth.

Normally i'd just remove the cooler but MSI uses those annoying warranty void stickers on the screws and if there really is something wrong with it I don't wanna ruin warranty for him.

I completely disassembled my 7970 lightning and they are still replacing it.

Who ever repaired the Lightning at MSI prolly pulled a chip from the wrong bin or it was mis-marked.

I had a 6850 with 6870 Shaders, and I've had a Sapphire 7950 come back as a 7970 before.
(I build PC's for friends and family and also do their RMA's)

Is it just me, or is xfire+eyefinity+DX9 a utter mess? I would have thought that it would have been buttery smooth considering how wonderful Skyrim ran on a single 7970 at 1080p. It is just a stutter-fest as soon as I turn on xfire, and a lag fest if I turn it off. Crysis runs better than Skyrim...put that in your pipe and smoke it.

Kinda making me wish I had gone team green...

It is just a stutter-fest as soon as I turn on xfire, and a lag fest if I turn it off. Crysis runs better than Skyrim...put that in your pipe and smoke it.

Kinda making me wish I had gone team green...

a 3rd card would fix that completely, but its not like nvidia doesn't have problems on SLI too, why do you think they don't support 4-way anymore?

what mods you using on skyrim that one 7970 isn't enough for eyefinity anyway?

Try using a framerate limiter and setting it to 60fps. NOT vsync but a framerate limiter. Gets rid of all the stutter on my eyefinity 7950 cf setup. Only game I play that I have to do that on.
