Hello noob here.

System
# Intel Core 2 duo e6600 Stepping 6 Rev B2
# P45 Neo-f
# Ballistix DDR2-800 2x1GB
# XFX Geforce 9600gso 768MB GDDR2
# 2x Seagate 320gb SATA300
# Windows Vista X64 SP1
# Rosewill RP550V2-S-SL 550W RT Input Voltage 115/ 230 V Input Frequency Range 47 - 63 Hz Input Current 12A @ 115V, 6A @ 230V

Currently Im running the system with everything set to auto except for the dram which I've put up to 2.07 for increased stability at 4-4-4-12. I have the fsb set to 333 and the multiplier set to 9 for 3ghz. It's set to 1:1 in the bios but its running at 5:6 in windows (It may be because of the ram timings). The vcore on auto right now is 1.375, the mch is 1.1 according to dual core center. Would relaxing the timings help, I am running in spec with the ram.

I can't seem to get it stable at higher speeds though no matter where I put the voltage.

The stock vcore on the chip is 1.325 so I realize its not going to be a super OC. I hear though that my voltages are high for an e6600 but other places say no. It may be that I got a bad batch.

I tried upping the voltages a couple notches to go to 350 on the fsb but no luck. I've tried upping NB and VTT but also no luck. The most I got was 2 hours of stability at a voltage that other people get to 3.6 on. I realize all chips are different, but this is annoying.

It always seems to be the same core which fails prime95. Not sure if that matters. Temps are fine according to Everest. Thanks in advance.

Edit: also for some reason the MCH will jump to 2.59 out of nowhere sometimes. Im not sure if its an inaccurate reading or actually happening since the computer doesn't explode.

Have you tried upping the FSB a little at a time? Sounds like your just trying to jump in (for 3ghz thats normally fine), I would set everything back to default, drop the ram divider and start raising the FSB in 10mhz increments.
How do I know when to raise the NB, FSB or SB though or should I never have to? Ill set it all to default and go to 343 and see how it goes from there. Do I need to run 12 hours of stability testing each time though?

Isn't the default FSB 266? I would start from 300 and work up in 10mhz, if it doesn't boot into windows or is unstable up the cpu vcore, you don't need to stability test yet, you only need to do that once you think you've got the overclock you want.

Edit: Please fill in your specs in the user control panel, this will help others answer your questions.

Just do a search there are some great guilds on this forum that will help ya out. Good luck and take your time. keep an eye on temps.
I have it stable at 333 and its set by jumper. You think I should set the jumper back to 266?
Jumper? Are you not overclocking in the BIOS? Didn't know they still did jumpers on mobos (apart from clear CMOS) but if it has set it back to 266 and overclock in the BIOS.
All I was able to get was 3.3GHz out of mine.

And my vcore is at 1.4875.


For me it's either the chip or my board. I ran 3.4GHz but it was not stable.

Mine is not good either. The vcore should be at least 1.425V when it working at 3.3G.
