I am having problems overclocking my new Q6600 past 2.63 Ghz (10%), anything past this and the system will not make it into windows without BSOD.
At first I thought this might be an issue with the stock cooler, but after upgrading to a Thermaltake Blue Orb 2, I found no difference.
The processor idols at around 24 degree's and 42 under sustained full load.
Based on what reading in the forums, this processor should be capable of 3 Ghz or more and my thermals seem to be okay, any ideas?
Core Voltage = 1.4v
Do I need to adjust other voltages such as front side bus as well?
A Vcore of 1.4V seems excessive for ~2.6GHz
Lower it to your VID (BIOS, don't use auto for voltages).
Check your RAM:FSB ratio.
It's probably 400:266(1.5) or 800:266(3.0) now so effectivly you're overclocking your RAM as you overclock your processor. The clock for your RAM rises 3 times as fast so at 300MHz FSB you'd be running your RAM at 900MHz (most RAMs can't overclock that far on stock voltage).
Also disable any AI/OC features your motherboard might have.
If you need further advice ask.
I was having mixed success trying some changes but now my Motherboard seems to be preventing me from overclocking at all!
Even when I set everything to manual and play with the speeds they automatically restore to defaults when I save an reboot?
Perhaps it my glitchy Asus P5N32-SLI Plus Motherboard, only a year old and both the ethernet ports have already died on it.
Bios updates are resets don't seem to help either.
This is the second Asus board that has had ports die on in less then a year, I think it will be the last one I buy.
Unplug the system from the wall socket for about an hour.
Try some overclock that worked before. If nothing else works accept the obvious. You have a NVIDIA chipset. It's not that easy to overclock them.
I think you should change what the motherboard is connected to over ethernet. I have a 3 year old ASUS A8N-SLI board and both ports still work like a charm.
