GTX 295 backplate - Overclock.net

LoweRider · 2 Weeks Ago

Just ordered it.

I got my card OC'd to 698MHz core clock, 1502MHz Shader clock, and 1178MHz memory clock.

The card sometimes fails on me and shows a grey screen that I cant exit out of and have to force my computer to shut down. I'm guess it's a heat problem, so I bought the backplate. I'm hoping for good results with it, and cant wait to put it on when it gets here.

..or maybe my OC is too high?

I'm pretty sure the backplate won't do anything if you don't have memory chips on the back. Backplates are designed to spread heat, but if it doesn't contact anything, what's the point? If they sell the card without the backplate or optionally, I doubt it does something useful. It seems to be for aesthetics anyway.

the back plate lowers the temps by almost 20c

Lol.

The backplate may be designed with aesthetics in mind, and that may be why some with sandwich cards buy it, and it also does cool the vram on the back of the pcb, but consider that:

A: It increases the amount of evenly distributed pressure on the thermal interface between the gpus and heatsink or waterblock.

B: Currently, only the Co-Op is made. All Co-Ops come with the backplate. Therefore, any modern GTX 295 comes with a backplate.

This is a single PCB version, and although iIrc, it uses some inferior surface mount components, (such as the absence of Volterra PWMs with software GPUv control) it runs cooler, and therefore OCs higher, and you can't necessarily get any higher of an OC by increasing GPUv on a 295, anyway. And you just can flash the BIOS, right?

23c if you lap your ram

It's got thermal pads that are on the back of the GPU socket.

Anyone else concerned with the weight these things might put on your PCIe slots? These things are heavier than Rosie O'Donnell.

You think that is bad, try it with a waterblock. I need to fabricate a support pillar, or some kind of multi-card support structure, to aid in further expansion.

It is crazy.
