Q8400 overclocking

To be honest neither the board or the CPU itself is among the decent ones for performance...rather than trying to squeeze more clock speed out of a limited CPU on a limited motherboard, I honestly think you'd best upgrade your platform if you can save up some money.

Even a socket 1155 Pentium G2120 around £70 would offer simliar/better gaming performance than a Core2Quad at 3.6GHz. And then getting a Gigabyte Z77 board around £80 (or a B-grade Gigabyte Z68 board for £35) and 8GB DDR3 memory for around £20 should bring the total to around £170 (£125).

Anyway, you didn't mention what you using the PC for...is it for gaming, or video encoding etc?

i can change the v core on the board but that dont seem to make any difference. Ive only gone as high as 1.45, As ive stated above i can make 3.20ghz on the g31 yet the newer g41 i can only get 2.77ghz stable, one thing i have noticed and have took note to a few times with other set up ups is to lock pci- 100 but for some reason when i go above 333 it locks at 102 could this be the reason it failing to restart?

Thanks for the advice on yet another set up but that is not an option at the min as have my sons birthday in november and then xmas.
 
Its kinda cool that you have v-core options as most boards with that chipset don't.
You may need more nb voltage to help stabilise you higher fsb speed. Also cpu-vcore might not be increasing in realtime windows mode, even though you've increase it via the bios.

Also your ram although it can support higher speeds than the chipset can provide theres going to be a tailoff where at a certain speed its gonna reach its max.

Don't know if this is teaching you to suck eggs but

1. Lower your ram multi to the lowest it can for now and concentrate on finding the fsb wall. So lower your cpu multi down to something like 5. Then slowly increase your fsb in small increments until you get near instability or unable to post.
Theres this thing called a fsb hole where at a certain range for example say 365-380 it may not post but before or after that frequency it will.

2. Once you know your fsb wall then you can find you max cpu frequency/voltage/ thermal threshold.

3. Then once you know your max cpu speed, then you can lower you cpu multi so you can find your max stable ram speed.

4. then devise a calculation to give you a best compromise between ram, cpu speed and fsb.


Be aware though that increasing voltages will reduce the lifetime of that board almost definitely.
