ASUS P5W64-PRO "32M PI"
"12m 11.594s"



DFI965-S "32M PI" [Enhanced Adrressing = "FAST"]
"12m 12.656s"




performance same


03/26 Bios problem
The Memory the Clock above 550@1100(2:3 4:5) is impossible

Nice one OC_Windforce


Ha ha, Lucifel eddition G.Skill RAM

[PotGoblin]

question how much clearance room is there between your tuniq and the nb heatsink on that dfi board? enough to squeeze a small 40 or 50mm fan in there?

[Dekara]

Interesting result, nice run .

[dinos22]

fark me DFI is REALLY fast in SPI


that bios RAM speed limitation is NOT good

[death metal]

nice, more!

[screwtech02]

Any way you can throw a couple PCI-E cards in both the boards and retest?? Like to see the results, without a pci vid card...

[RealTelstar]

1s difference... uhmmm.

How did u find the DFI btw? is the board rock solid?

I believe that it's more than bios problem- the same thing with Abit quadGT- max what I have seen on quadGT is 1180! I think its because of strap 1066! So if there wont be strap 1333 in newer bioes we wont see higher clocks on mem!

[DeDaL]

thanks for shearing.
really fast for 965

no such problem with asus commando

long catch, but try to disable every peripherial except the essenstial ones,
(disable USB/LAN/AUDIO)... i think it worked somehow for me on the asus commando

lol what's max FSB on that commando using strap 1066? Is it 500+?

[Okda]

as expected from the late dfi mobo

now i can convince myself to update to C2D

i don't have a screenshot handy, but its around 550Mhz

[EMan]

So, based on what I've read (not personal experience), does this sum up current mainstream chipsets:

975: fastest clock-for-clock (esp 1:1 memory), but low fsb ceiling
965: maximum fsb, but most boards run on slower strap at higher speeds
965 (1066) (DFI/QuadGT): faster clock-for-clock than other 965 at higher fsb rates, but lower memory bandwidth ceiling limits top speed
680i: high fsb (but not as high as 965), fastest extreme cooling potential due to unlinked memory, SLI for top 3D performance, but expensive, and can be a bit buggy

Yeah right!

max FSB using strap 1066 on commando is same as P5B dlx- 450-470!

Of course most of you are reaching 500+ on commando but it switches to strap 1333 after FSB 450-470!

[doom_st]

not if you boot @400 and clockgen to 500+

ooops im sorry, my mistake not so much coffee today

yes the 550MHz is with 1333 strap, in that case booting above 400Mhz
with 1066 strap ill have to double check


but the memory overclock is great with 2:3 and 1066 strap, i can do more than DDR1300 with 5-4-4-6
and not at 3xxx but at 5100Mhz

the only bad thing is that i think i lost some cpu overclock (100-150mhz) with 965 compared to 975
