Hi Guys

Overclocking my E6400 was easy, I got 3.2Ghz stable using 1.300v (cpu-z: 1.27v)

System:
P5B deluxe
E6400 @ 3.2Ghz (8x400)
CORSAIR 2GB DDR2 PC6400 XMS2 XTREME (5-5-5-12-T1)
Coolermaster Extreme 500w

NB: 1.25v
Memory: 2.1v
PCI: 101mhz

2.8Ghz OC: http://i10.tinypic.com/3y6x4di.jpg (This one shows memory timings)
3.2Ghz OC: http://i16.tinypic.com/2ivd087.jpg

I know a lot of you guys have the same rig so I think I ask here for some advice - the funny thing here is that my memory is set to Auto in bios (according to CPU-Z its: 5-6-6-18) and I want to tighter the timing so when I manually set the timing to 5-5-5-12 which these memory should hold my overclock goes dead and the PC wont post,

Any ideas?
 
Thanks, I've read that thread a few times and everyone is crossposting eachother but I found Memset 3.0, that could be usefull to try different timings.

Stand by... will first make a WindowsXP restore point

You do have the memory ratio set to 1:1 right?

Yes sir.


I changed my timings using Memset 3.0 to 5-5-5-12 and it was successfull! Saved a whole second in SuperPi - But I do not know the stability

If I do the same thing in Bios it wont post.

Researching...
 
The last 4 memory timing values given by P5B boards in manual mode are wrong at least for some Corsair sticks.

Defaults with my 6400C4D (CAS4) sticks were something like:
5,5,5,18,6,42,10,10,10,10

And with these values there are no problems:
4,4,4,12,6,42,3,11,5,14

You can set the first 4 according to memory specs, but the other 6 are also critical.
 
1.3V? You're undervolting? Isn't the stock voltage for the e6400 1.325V???
 
If you can fix that memory problem, you can go a lot higher with that board.

Im at 3.7GHz with my e6400 @ P5B Deluxe, 1.425v, tuniq tower cooled.
