WOO! Just did a quick try for my [email protected] 256.5x16, and it posted, booted, and everything is A-OK! Who thought a 915 chipset could breach the 250FSB barrier? Not me for sure...

CPU: 4103Mhz FSB: 1026

I'll be shooting for 4.2Ghz tomorrow...I really want to get some good cooling now though! Now that I know I can go 4.0Ghz+, I'm gonna have to get rid of stock to cool this baby down and go higher

Ehh...Only one problem, Dual-priming I get an error after a few minutes so I think I'm gonna have to up the vcore to keep a stable 4.1-4.2Ghz clock under 100% load...

But I won't be shooting for that until I get away from stock cooling and go aftermarket...I'm thinking BTVX/Scythe Ninja/AC Freezer7 Pro w/ FM91...

We'll see.

Or do you think I might need to bump up the chipset voltage to keep it stable at this high of a clock? It's currently just on AUTO, priming @ 41C...

Should I bump it up and try again?

Perhaps I missed it, but I couldn't find your Vcore. I don't think that I would up the voltage very much, until you upgrade your cooling.

Voltage to the NB should be okay on "Auto".

Another factor might be your timings, maybe a little looser?

Anyone else?

My vcore is set on 1.4000 right now from the stock 1.3875. I've had to keep it at 1.4v since 3.9Ghz for stability, so I guess it could need more for 4.1+

I just tried raising the Chipset voltage from 1.5 to 1.6 and i still got the same error while priming :-\\

When I upgrade my cooling, I'll try 1.4125 vcore I suppose. Should I try raising my FSB Term. Voltage also?

And nah my timings are fine, these are the stock timings rated for DDR400 and I'm only running DDR405 right now, they went all the way up to DDR450 with 2.5-3-3-7 back when I was sitting at 3.6Ghz.

Thanks for your help so far

that is awesome.
i have the AC Freezer7 Pro. its not a bad heatsink. i also0 got the ceramique thermal grease. there is not a b ig differance from factory. i probably didnt need it. but i have always heard its not wise to OC with factory heatsink. i guess you proved them wrong.

i wonder how far i can actually push my cpu. i have 3 90mm fans 1 120mm fan and the fan that came with the heatsink i bought. i have had this cpu OC'd to 3.5 Ghz so far and ran stable. cpu at 100% was about 60.

but now i bought 2 seagate sats HD's and if i OC more then 5% when i restart it bios wont recognize my HD's and then says overclocking failed.

=(

here is my thread
http://www.overclock.net/intel-cpus/...-over-5-a.html

please help

=(

Hey, before this core 2, I had a pent D 930 @ 4 ghz 1.4 vcore. After 2 months it burnt up
It was running 30's idle 60's max temp. Im not too sure as to why it happened, but it was not a fun experience. I hope you have more luck than me!
And very nice overclock for that chipset, wow.. I had a 945 chipset, p5ld2 (has vcore droop
)

Well as not many people know this, my secret for helping ASUS owners is as follows. If your BIOS has under the "JumperFree Config" section a "Performance Mode" selection, change it from [AUTO] to [STANDARD] or even [TURBO] for the highest of clocks. I had to go from auto to standard to make it from 3.6Ghz to 3.9Ghz, and then to turbo for 3.9Ghz upward. Chipset core voltage doesn't seem to have any effect on the FSB or anything as I just leave that and FSB term. voltage on AUTO.

Check your BIOS for that setting though and see what you can get out of it. I know that almost ALL 945 and below chipsets have this setting when you have an AMI bios... Others I don't know, but it should.

Get back to me.

Nothing. I'm thinking it's more of an issue because I can't lock the SATA bus. If I pull out my SATA drive and use an EIDE one, it goes a lot higher.

Ahhh...I gotcha. That's weird though, as I run two SATA HDD's and 3 IDE Opticals and I have run all the way up to 256FSB. Hmm, does it post if you go over 219 with the SATA's in and it just doesn't boot windows or does it not post at all?
