Hi,
I have an Asus P5b board, Q6600, 4gb pc2-8500 ocz reapers and have been trying to overclock on air. I have 3 case fans and a good heatsink/fan.
So far I have got to 3ghz with 9x335 with core temps of 46c on full load, ram at 1005mhz. There is room to overclock more but I'm not sure about the board.
I have v-core range of 1.525-1.7v and memory voltage of 1.8v-2.1v. I think the memory voltage limit is the problem can anyone confirm this or give another option?
P.s there is no nortbridge adjustment.:(
 
Your v-core range looks high.
I dont quite get what your asking? Are you saying your overclock is not stable?
Your motherboard should be fine for abit more. You should be looking for about 1.9v for your ram.
 
Yea your Vcore is really high.

Mine is 1.325 for 3.2Ghz.

However, as already pointed out, what are you actually asking?
 
I just want a stable setup running up to 3.6ghz.The ram specs state the ram runs at 2.1 to 2.3v, so at 2.1v I should be ok there.
Do i have any other options to turn down the v core as what I have listed are the options.

There is something wrong eith your BIOS if thats the vcore range! You may have a jumper or setting within the BIOS itself thats allowing these silly high voltages.

You are correct, I am mistaken there are more voltages available. So far I have managed to get 3.33ghz stable using 370mhz fsb & 9x mulitiplier. I have not been sucessful in applying v-core voltage as it won't boot when I do, so I have it on Auto.
Whilst gaming I see a max core temp of 54c but when using intel burn test it shuts down!! what do you think?
If I had northbridge settings could I get more?

The power stage on the P5B isn't strong enough to do 3.6ghz on a quad.

If you keep an eye open you can pick up a P5K-E (vanilla P5K is no good either) for about £40. That will see you to 3.6ghz, providing your chip/cooling are up to it.

Ok thanks. I bought this board as an overclocking upgrade to the G31 based board I had before. I really need to do my homework better lol.
 
I made a similar mistake... it is very cheap and easy to do though - grab one from the auction site and sell yours afterwards, net cost is about 20quid for an extra 15% performance... bargain :)
 
It's definately the mobo, but it is possible the CPU won't do it either. Unfortunately you'll never know unless you swap the board for a more capable one :(
 
I'd try lowering the multi to 8x and run 8x400mhz and i'd find best stable clock as close to 1.4 volts or under as possible.
