PCI-e Overclock

[Mr_Flibble]

Hi All,

I wish what is a safe maximum for overclocking the pci-e bus before things get risky.
I ask as i have one of the freaky ASUS p5b-vm motherboards and increse of the FSB has to be matched by an increse of the PCI-e bus. So far i have the FSB at 303MHZ and the PCI-e bus at 111MHZ giving me a not too bad 18.884 second super pi with the E6600 running at 2726MHZ
Im sure i can get more out of it if i just increse the PCI-e bus a bit more but im unsure how far i can go.

Also how possible it it to volt mod the motherboard to increase the memory voltage. At the moment im having to run a divider on it presumably because i cant give it enough juice. The motherboard tops out at 1.95v and my memory is rated at 2.1v. So far i feel the motherboard has been wasting the optential of my conroe 6600 and gskill 6400HZ not to mention the watercooliong

Any tips or advice in getting more out of my rig greatly appreciated

Hi thanks for the replys, the problem is that the pci-e lock doesnt actually work on this board i can set it at 100 but i then can only raise the fsb a few MGHz. I have to increase the PCI-e bus to increase the fsb a worthwhile amount.

Unfortuneately it seems asus isnt going to fix the pci-e lock issue

So looks like im stuck at 2.7 unless i want to risk upping the pci-e - or get a decent matx board if one ever comes out.
