Trying to get E6600 to 3.4Ghz

[rounddodger]

Hi just been tinkering with my overclock for a couple of days and managed to get it orthos stable for over 6 hours on blend test @ 3.3Ghz on the following settings :~

CPU FSB: 367Mhz
RAM DDR2: 734Mhz (1:1)
PCIE: 100Mhz
PCI Clock Sync: 33.33Mhz
Spread Spectrum: Disabled
Mem Volts: 2.15
CPU vCore: 1.4
FSB Term V: Auto
NB vCore: 1.25
SB vCore: Auto
ICH Chipset: Auto

Multiplier is 9 and disabled all the throttling stuff, speedstep etc.

No problems there, temps hit max of 50 degrees C per core on Orthos blend test and runs very nicely but just want to see if I can reach 3.4Ghz then just leave it.

I can get XP to boot with FSB 378Mhz (x9 = 3402) but literally crashes shortly after loading something up, speedfan or whatever and mouse freezes. At first the Mem volts were 2.10 but it wouldn't even post so increased it to 2.15 and it would boot but don't want to go higher (next is 2.25) can the RAM take it?

Any idea's for getting me to 3.4Ghz? Thanks!

I would put the ram on a divider for now and just concentrate on getting the cpu stable.

Try putting the memory on a divider and upping the volts on the cpu to 1.45v also put your memnory back to 2.1 for now.

See how you get on, let us know.

RAM is not your problem. At 3.4 your RAM will be at 756MHz, which is actually underclocking it since your RAM is PC6400 which is rated for 800Mhz. I'd set it back to 2.1v.

Sounds to me like you need to raise your FSB and ICH voltage by 0.1v and see if that makes any difference.

Increase your cpu vCore by one notch, if that doesn't work increase it by another. Don't go past about 1.5 though.

Remember, asus boards tend to have hideous vdroop :/ I've got my e6600 at 3.4 at 1.5 vCore in the bios but cpuz says only 1.47 :| (on an asus p5ne-sli).
