Prescott LGA775 + 865PE... let's clock!

New here guys - Hi -

I'm considering getting this board, or maybe the DFI LGA775/i875 hybrid.

Question: Has anyone tried a P4E 550/560 using the 14X multi unlock feature??? :idea:

Seems like ~280 - 285 FSB X 14, & some decent PC4400 @ 1:1, would be a pretty nice 4G system. This is my goal on air.

We've been playing around with this exact set-up using Asus S478 at OCC in this thread HERE.

I'd like to duplicate our results using an LGA775/i865/875 hybrid, since we believe the Asus S478 mobo power circuitry is a limiting factor (needs lots of mods), and the LGA775 mobo powerplants MAY be a more robust alternative.

Pleasure to meet you all.

hi all. New test :banana:
With BH5 and OCZBooster. P5P800 No mod Water cooling(water +20°) the maximum frequency that I have closed superpi is:

And with +0,050Vcore :

Now i need Vdroop ;)

Here's my shot at it... 3.0E and an AS8, too bad I've gotta run 5:4 with my 3700EB (which equals 240 Mhz for the Memory... :()

looks good. what voltage? cooling? timings? nbstrap? ht on? :D

1.65V Vcore, 3.2V Vddr, 1.65V Vagp (can't get any higher with this board :(), Phasechange, 2.5-2-2-6 (5:4), FSB800 and HT is on.

Too bad it won't boot with PAT enabled...

Vcore from bios in AUTO is 1.35-1.4v...cpuz 1.56v(bug)..y have one screen with vcore default and cpuz 1.960v :)

From Asus probe...with air(stock) 40° idle..with WB and water 20° probe it says 15° !!! :p: still bug? :D

Cool!! :slobber: What cooling? Phasechange ??

Ops..i see now :) Phasechange :D Prome o Vapo?

It's a trusty Mach II GT - don't know about the temps since the AS8 won't show sub-zero temps, but I guess they are around -25°C idle and -10°C to -15°C load.
Gotta get some new RAM to run sync, I'm sure I can hit the 27 secs then.

Maibe with more voltage on ddr(3.4v)you can try 2-2-2-5 :rolleyes:

the 3700EBs don't gain much performance with tighter timings anyway... I'll get some nice RAM to run 1:1 sooner or later. (GSkill looks like a nice option?)
