How's this overclock on my E6400?

[Icelight]

So I've been working 'hard' today getting my new processor all overclocked.

I wanted to hit 400FSB and stick at that speed, and I managed to do it!

I had to set the vCore up to 1.375 (stock: 1.325) to keep it stable, but it seems to be working perfectly now.

Ran Orthos on Small FFT's for an hour with no problems, and temps never went above 47C! (as per the Intel TAT readings)

Are these temps/vCore considered to be ideal for this kind of overclock, or are they a bit high?

Hmm, having some weird things happen here.

It was running Orthos fine for another 2 hours yet.

I shut off the computer and come back it it 30 minutes later, boot it up, and it does the usual boot-reset-boot-reset thing, like when an OC isn't stable.

It now *refuses* to boot at 400FSB. I even tried setting the voltage up to 1.425 and it still won't boot...Any ideas why all of a sudden it doesn't want to boot, when that OC was perfectly stable before?

i wouldnt call a 1 or 2 hour stable computer perfectly stable 12+ hours ok maybe but I have had oc that would fail 6 hours in and I dont think its perfectly stable, perfectly stable would be never error

is your ram stable? have you mem tested it?

have you tried upping hte NB or SB a little to see if that might help. Relax timing on your ram to rule that out.

some boards have a dead spot from like 400-430 I think that they wont run, try 395 or like 435 if you can My board does not have a hole but I know alot that right around 400 have problems so that might be doing it

Yes I ran Orthos 3days 26 hours and allowed memtest to reach 3700% without any errors what so ever! You should run Orthos and Memtest for atleast 4 hours.

Well, I ran Orthos for a little over 4 hours today with the settings of:

380Mhz and Auto for the voltage settings.

Computer has cold booted whenever I press the button, which it wouldn't do all the time at 400FSB.

No errors and temps stayed around 47C.

I just don't understand this...according the CPU Z the core voltage is at 1.360...which is well below what I manually had to set it to for the computer to boot up.

Now, either the auto settings do some magic, or CPU Z is not reading that correctly ...

CPUz does not do a good job of reading voltages. I usually check the "hardware monitor" section in my BIOS for the actual voltage reading. On most boards there is going to be a droop. For example, when I set my voltage to 1.375v in bios it's really around 1.325v. What voltage is your memory rated for? Set whatever number it says on the sticker in the BIOS. What timings are you running?

[Icelight]

Is it possible in the 965P-DS3 to see what voltage is currently being sent to the memory? All I can find is the 'memory overvoltage option'.

Right now I haven't touched the memory, it's at 5-5-5-15, but rated for 4-4-4-15 and, I believe, 2.1v (It's OCZ Platinum XTC Rev.2).

Thanks for the tips though, I'll be working on this tomorrow after my 'real' work is done :)

I'm not sure if you can see the actual voltage going into the memory on the DS3. It's been a while since I used one. I would go ahead and set it at 4-4-4-15, 2.1v, 400mhz. Drop your CPU multi down to like 6x to ensure it's not your CPU causing the problem.

[Icelight]

The problem is though, I can't see what voltage is going into the memory at all...

All I can do is set 'overvoltage' of the memory, by a certain amount, ie: 0.1V, 0.2V, etc.

I set it to +0.1V for now. Computer is still booting up fine at 380Mhz, hopefully it stays that way :\

*Slaps head*
I forgot to disable that C1E and EITS or whatever they're called...could that have something to do with this semi-randomness?

[inkfx]

Disabling those features just make sure your CPU doesn't go into "power save" or whatever they want to call it. (meaning the multi dropping down to 6x at idle) IIRC, the default memory voltage on the DS3 is 1.8v. So a +.2 would mean you're at 2.0v. This is how I did it back when I had my DS3. I don't believe their method has changed unless specified so in a recent BIOS update. To be on the safe side I would recommend keep going with +.1v whenever needed.
