Hmm... I did not know this.
Is it possible to flash back to F9?

Of course, I tweaked it just a tiny bit and ended up with a fairly stable 4.0 GHz overclock within a matter of like 10 minutes (or however long it took me to go through this template).

But now after seeing your overclock of 4.25 GHz with just 1.26V, I can see now that I probably don't need 1.280V under full load!

Anyway, I finally tested the overclock for the first time on Tuesday night and it passed 100 runs of LinX with a Problem Size of 21366 (or, 3500 MB of memory). The CPU's core temperature never exceeded 60°C either.

At that time, my MCH Reference was set to Auto. So then hoss311 had me manually set it to somewhere between .680 and .720, and so I decided to shoot for .680 just to see what would happen; it's going well so far! It passed 100 runs of LinX again with a problem size of 20980 (3375 MB)! So thank you again, hoss!

Now, I'm curious about one thing: why 500x8 instead of 445x9? Is it just because of how 500x8 sets it to precisely 4000 MHz as opposed to 4005?


The Thermal Specification is 71.4°C, but this has nothing to do with the core temperature. Here is Intel's definition of the Thermal Specification:
Take notice of how it is measured on the "geometric center on the topside of the processor integrated heat spreader": this is the same place where the heatsink makes physical contact with the CPU.

But the Tj. Max of this CPU is approximately 100°C, and it does indeed refer to the CPU's core temperature. This is the temperature where, if it were reached, then the CPU would turn itself off. It is designed this way just in case it is installed in a system where the motherboard has no such protective measures.

So if you're running a stress test and see that the temperature is like 80°C, then don't panic with thoughts of permanent destruction to the CPU: that's still a distance of 20°C to the Tj. Max (or, the "Thermaljunction Maximum). There are people here on Overclock.net whose 45nm Core2 CPUs have exceeded 90°C for longer than 10 minutes and are still running just fine today.

So 66°C under linpack is fine.

Edit: Here's a great article which is very helpful on this subject: http://www.tomshardware.co.uk/intel-...ews-29460.html
Well, it really depends on your RAM. I use the 500x8 (now running 500x9 though) method because it gets me closer to my posted speed of 1066mhz RAM, I haven't taken the time to really push some FSB runs on my RAM to see how high I can get it above the rated 1066 and how much I need to loosen timings or increase voltage to get it there. From what I've read, the Mushkin sets are binned nicely, and should actually go well above their rated speeds with minimal effort... is yours a 800mhz kit? 900? 1066?

Obviously the closer you can get it to the rated the better. I can get mine to boot at 533x9 (right around 4.8GHz) but this cooler can't handle the temps. Next step is some FSB runs to see what I can do with this RAM to get it up near a 1110mhz range, as I want my PC running 24/7 at 5ghz once I get her under water. Water should be installed within the next couple weeks and then its time to realllllly beat the **** out of her.

I'm still not sure which route to go though, I want to upgrade to a Q9550, they're such great values at Microcenter and if I get a decent chip, i'll certainly get her over 4ghz under water but the 2 extra cores make me a happy camper. BF:BC2 would love the extra cores, and thats frankly where I see the largest slow down... everything else I can run to hell and back. Other than BF:BC2, everything else is more or less Source games... and I can hit upwards of 300FPS in those anyhow

As to your voltage remarks, If you go too low on voltage she should crash rather quickly, so get her rock hard stable at 4.00ghz with the current voltage settings, and then do quick prime runs with one click down on your voltage until she doesn't survive say... 30 minutes or so on Small FFTs. Once she crashes on Small FFTs, raise the voltage one click and then give her another long session of either Prime95 or LinX (I prefer Prime, never use LinX... matter of preference as you debated a few pages back )

These chips really don't need the volts until you start pushing beyond the 4.25-4.5 range. I'm actually running mine at 4.5, stable for 3+ months, with it only shutting down if a windows update applies while i'm sleeping and it needs the restart. So... 3 months stable. At 4.5, I'm running at 1.32 I believe. 4.25 is 1.26v... 4.8ghz I'm only about 1.36v but like I said, temps run amock.

It's 800 MHz. But this reminds me that I tried 500x8 and then put it back to 445x9 just because I need to keep the memory clock as close to stock as possible. But I admit that I would love to use 500x8 just because it's like I said: it's a perfect 4.00 GHz. hehehe Oh man I'm so anal.

I love this advice! Thank you! One of the reasons why I like this is because it means I'll be able to spend more time testing and tweaking the settings (I'm hoping that it will encourage me to do so). My impatient side wants me to just stop after I'm finished with this extreme testing plan that I have, but my last board was the lowly EVGA 680i SLI (122-CK-NF68), and so I think I'm way overdue to get down to business in the same way everyone else does here on OCN!

I mean, with that board, all I really did was set the overclock, did my extreme testing, found it to be stable, and then I just left it without trying to see if I could use less voltage or anything like that (I didn't try to get a more professional overclock). But now I have a real motherboard, so I'm finally enabled to do great things!

This makes me curious about one thing: what does Core Temp say your E8400's VID is? Mine's 1.2500V.

does the lenght of the time it takes before it crashes means your getting closer to stability ?

Sometimes, yes. It can mean you're on the right track. Bump what ever you just bumped, again.

i jumped about from 9 10 12 beta and 11 a few times with mine before i settled on f11.

not 100% now but i think after i used 11 the first time i was stuck with it as my back up bios tho, not that i see that as an issue as once i got the settings right i got the best performance for f11.

I don't understand why everyone says that BFBC2 is so hard to run... I have it maxed out and I play just fine

My impatient side wants me to just stop after I'm finished with this extreme testing plan that I have, but my last board was the lowly EVGA 680i SLI (122-CK-NF68), and so I think I'm way overdue to get down to business in the same way everyone else does here on OCN!

I mean, with that board, all I really did was set the overclock, did my extreme testing, found it to be stable, and then I just left it without trying to see if I could use less voltage or anything like that (I didn't try to get a more professional overclock). But now I have a real motherboard, so I'm finally enabled to do great things!
Don't worry. It's like an addiction. As soon as you start tweaking, you'll never want to stop. I mean, I was just like you... I wanted to just get a good overclock and keep it there. But now I'm trying to squeeze every ounce I can out of this thing. It's fun. Pisses you off at times ("WHY WON'T MY MCH REF GO HIGHER!!1!!!!! FFFFFFFUUUUUU") but it always keeps you coming back

not 100% now but i think after i used 11 the first time i was stuck with it as my back up bios tho, not that i see that as an issue as once i got the settings right i got the best performance for f11.
ya I was going to go back to F9, but then I saw that they released F12. Now I can't decide

Oh well. Guess I can just try them both

Ok, I am officially (and finally) very impressed by the EP45-UD3P. I just did some tweaking, and so here are my "before and after" settings:

Before:

CPU Vcore...............1.35625V (1.312V idle, 1.280V under load)

MCH Reference.........0.718V
ICH Core.................1.200V



After

CPU Vcore...............1.27500V (1.232V idle, 1.216V load)

So yeah, I am hooked. I started tweaking gently at first, and then I just kept tweaking and tweaking. But I decided to stop here and post about this little adventure.

I am amazed it's even working!! Although, I haven't tested it yet!
