Thanks again Ghostleader. I think I'll go for a Sapphire Vapor-X 4890. I figured I could always use my 8800GT for physx should the need arise. I can't find the toxic/atomic versions in stock anywhere, just the regular vapor-x which I expect will perform adequately (I know it doesn't support software voltage control but I'm not really bothered with that).

Nice choice, an other awesome piece of machinery from Sapphire.

Sorry guys for the , better get back before someone us.

Armored_Kech1, what kind of cooler did you get for the NB?

I would rather say that 4870x2 increased temps near mch so you had to increase it's voltage.

Don´t think so, I cool the MCH with water, never over 35C.

I think that a voltage raise of 0.02V or 0.04V isn't actually a voltage raise. There's a good chance that if you stress these GFX cards that the load on the PSU makes the voltage drop a bit on the NB and needs to compensate with one or two steps higher voltage in the BIOS.

Could be, could be but I think that my Thermaltake Toughpower 1000W can handle that stress though and I still believe that the data throughput that Crysis produce is more then Prime95 or LinX can produce and therefore I have to increase the volt.

Also when I benchmark Crysis my water temp (only CPU and MCH under water, GFX stock air) increases by 2-3C if I compare it with LinX (max problem size, max memory use) even though the CPU temp is lower with Crysis then with LinX.

Go figure

You are right. Crysis is probably producing more data throughput.

Are you using your E8600 CPU? That could make sense.

If you use your Q9650 the data throughput is going to be twice that high for the same CPU speed.

It´s with my E8600.

Gonna test later with my Q9650, 4x2 Blades and those Sapphire Toxic HD 4890 in Crossfire, it gonna be a tough test for the RF, looking forward to it.


Right know I have done some test with the following gear:

ASUS Rampage Formula BIOS 0902 / E8600 / 4x2 OCZ Blade PC-9600 / Sapphire HD 4870x2 with Windows 7 RC 64bit.

I can´t make 4x2 of those Blades stable @ 1200MHz with 1,80, they need ~1,85 (1,84 set in bios), if I run 2x2 there´s no problem with 1,80 though.

Couldn´t go lower then 1,55v through the MCH to have it stable.


Here´s some screenies with my E8600@500 4,25GHz and 4x2 OCZ Blade PC-9600@1200 555 15 tRD7 Strong.

~5 hrs P95 blend (4x1600mb)
~5 hrs LinX (25 loop, max problem size and max memory use)
~5 hrs HCI Design Memtest (~500% with 8x900mb)
~3,5 hrs Crysis Benchmark Tool Assualt Harbor 90 loop

Stable enough for my.





Oh yes, she made it through all 25
