Had a chance to bench a 870 ES CPU on the P55A-UD6, was not a whole lot better than the 860 ES. As I compared this 870 ES to other retails I can see this chip requires a fair amount more of vcore as the OC is upped and still does not like extreme cold very much.

All of this was done on SS Phase and as I got to around 4.6ghz it was really stressing the Phase unit because of the vcore need to boot and run benches.

Cascade operation was just to painful as it seems to CB not to far past what Ss Phase could do so I would have to shut down the 2nd stage to get it to boot, then fire it back up and heaven help you if you had crash and had to reboot. While I was at -100c it really didn't seem to help much and this chip was very unstable so I stopped Cascade operations.

If this seemed like a good chip I would have gotten some DICE but I didn't think it was worth the cost of DICE to even mess with this CPU.

So here are some screens of how it all went down, starting at 4.0ghz and going as high as it would take me.

4.0ghz 2D runs


4.0ghz 3D runs with 2x 260gtx's in SLI


4.4ghz 2D runs


4.4ghz 3D runs 2x 260gtx's in SLI


4.6ghz 2D runs


4.8ghz 2D runs



Final notes:
I compared my results with the AnandTech results seen here

I see that they are usin a few different RAM timings than I have so I will try and see if I can get the ones they used on mine and what the results might be. They do not seem to show there RAM speed tho. I did take mine up to 2000mhz but it did not seem to help so I went for tighter RAM timings which did help me out. My chip would simply not boot at the vcore they used :(
