Asus Rampage vs DFI P45 T2RS with 4870X2 Crossfire

[Viss]

Compared X48 with P45 today. Unfortunately i dont have a DDR3 P45 board so its DDR2 on the DFI. Not sure yet if difference wil be (much) bigger with higher clocks on CPU but i think the cheap P45 did a nice job
Slots on the DFI are rather close, just enought space for the power connectors with dual slot cards:





X48 Chipset:
Asus Rampage Extreme
E8600 Q820A597

very informative results. Interesting that vantage cpu test 2 is slightly quicker on ddr2 but test one is slower by a fair margin

Nice compare .....

Thanks for sharing Bart-Bro!

Thanks for sharing, when Foxconn Avenger will be rls things will change regarding p45 in 3d

Keep pushing it

[iULICA]

Very nice,test pi 1m please

Can u test the difference between the mobos with single card?

Why gpu-z reads different clocks?

maybe that will fast for spi 1m too

nice work viss waiting for ln2

great work Bart,CrossfireX seems to work better in 16x+16x than 8x+8x,any real game for comparison?

thx

[roedzzz]

Nice compare dude

[DeDaL]

Thanks buddy, its very informative.
Nice too see some outstanding tests.

Thank you all Ran all the 3Dmarks again tonight on DFI with 8x600 and simular result compared to 8x600 on Rampage.

Very nice,test pi 1m please

Did a few pi runs that are here. More to come soon, i may have found me a good Q822A435

Can u test the difference between the mobos with single card?

Not too sure about gpuz but this version always reads me default clocks. 2.6 did a better job for clock info. I wil run single card soon to compare

great work Bart,CrossfireX seems to work better in 16x+16x than 8x+8x,any real game for comparison?

thx

Thanks mate much appreciated. I dont play games often (other then 3Dmarks) so excuse me for that. From what i have read though difference in games can be bigger in favoure of X48 but im not sure if its actually true.

hehehehe
no worries Bart ,keep the great work

Very nice comparison. Seems that DDR2 looses on 3d. I wonder how is possible Rampage to win on 3d but loose on superpi

X48 has 2 slots working 16x with crossfire, the p45 at 8x. DDR2 and DDR3 was necessary because i dont have P45 DDR3 board yet. It think its something in bios that makes the DFI very fast in 1M, only 1M though and with E0 chip...

[eva2000]

great stuff always good to put some concrete numbers behind known facts (x16+x16 > x8+x8)

[GazC]

Nice comparison, it's made my mind up not to do anymore upgrading until Nehalem is out.

I wouldn't be happy running crossfire with those cards for any length of time given the very limited clearance between them!!

The single card test???

Thanks for sharing.

*edit* Just saw you already answered my question.
