Presler Clocking

[Arthalen]

I know most of you are ooohing and ahhhing over Conroe OC's, but I've just had sidestep manouver and got hold of a Presler 945.

Had some initial problems with clocking this, but now I've sorted that out, I'm happy to report that I achieved my first goal with this chip.

FSB 240Mhz = 4.08Ghz Clock, Mem set to DDr2-800 gives me a SuperPi of 31.984.

Very happy atm, as this means I've broken the 4ghz barrier reliably, with decent temps and more headroom to go!

Its really put my 805 to shame .... best 24/7 OC in sig below on that chip.

So, the 4Ghz is hit, next step is 1Ghz FSB at 250, want to break 30 second Super Pi as well and see just how good the DDR2-533 Value Select ram is


Will report back soon ...

To be honest, i was expecting a lot faster, but it seems dual core sucks for superpi, my p4 630 (3ghz prescott2mb) @ 4.1 ghz does superpi 1mb test in 33 seconds (with HT enabled), have you disabled one core for supuerpi or something?
My ram is ddr-2 533 btw...

How much volts are you pushing through it?
I think your cpu should do 4.5 ish with good cooling, i dont want to volt mine more due to temps, but you say you have good temps so i'd try to get it to 4.5 ish step by step, but check temps on each step...

SuperPi is single threaded, so the results are no different realistically than an equivalent CedarMill - and my 945 has no HT support, not that it needs it

The real benefits will show in 3DMark06 I suppose with its multithread support, and Quake 4 that benefits from Dual Core.

I look at SuperPi as being a quick and dirty test to see if a OC is going to bomb out before upping the FSB more.

Volts: Stock Vcore, it runs at 1.265v, which is what I've set in Bios. But with the board mod I have to prevent Vdroop, It runs 1.365 so its giving me some headroom to clock straight away

Anyways, I'm off to see if I can go higher
