Yaay - 3.2Ghz from E2140

[Guy7]

I've managed to get thru 333Mhz FSB - hooray! Had the FSB up to 400Mhz with the E2140 running at 3.2Ghz. I can't begin to claim it was stable although some further tweaking may make it so. It did run long enough to score 997 on the CPC benchmarks. Managed about 20 minutes of Orthos with no errors before the PC rebooted out of the blue.

To do this though, I had to break the "set PCI-e bus to 100Mhz and leave it" rule. The only way I could raise the FSB (apart from increasing voltages) was to *raise* the PCI-e frequency. At a rate of roughly 1Mhz PCI-e to 3Mhz FSB over 340Mhz FSB - so at 400Mhz FSB I'm running 120Mhz PCI-e.

Is that bad? Is the BIOS telling me porkies?



Can anyone shed any light as to what might be going on here please? Ta.

I found my E2140 didnt want to boot running @ 2.8ghz, so i just pushed straight to a 430 FSB, and found a sweet spot @3322ghz

i think it was an FSB hole. Going to try for more soon, as i'm sure i can get it to 4ghz with a little volts

I never touched the PCI bus. Left it @ 100. Just gave it some good old fashoined thrash.

Hey Skull, nice to see you over here (as you've probably gathered I'm Seven_Guy on CPC). I think in my case the limiting factor is the mobo (Gigabyte GA-P31 DS3L). I've just brought the BIOS up to the latest (non beta) release and I seem to have 3.2Ghz stable right now :^)

One thing I have learned is how much *everything* affects your mileage in this game. I've just finished an FAH unit so am going to Orthos the CPU to death for a bit and see how it holds up. Mwahahahaha!

I see you're M0 stepping too whereas I have the old L2 stepping which makes a difference thermally AIUI.

Aye, i have just read in CPC about the different steppings. I've just fried my XP install after corrupting it with a bad overclock on that chip. Turns out, i'd left my vmod turned up, and put nearly 1,7vcore through it CPU is fine,and it's given me an excuse to try Vista.

Also, i'm using a Scythe Ninja with a mighty Delta 120mm fan to cool this baby, so i'm not to worried about heat. Before binning my XP install, i'd managed to boot to windows @ 3500mhz, but then it went :nopitty; but i don't think i managed to bag a CVF file in time.
