Cool Gigabyte GA-8I945G with PCI-E Volt adj

Hi All,

I've got a giga-byte motherboard GA-8I945G.
I'm running a P4 extreme 3.6Ghz 2Mb cache etc.
1Gb DDR2 533 (probably upgrade this soon for my BF2 load times[at least what some guys have told me, that RAM affects load times])

I've got a XFX GeForce 7800GT PCI-X (16x) 256Mb

Also 600Watt PS (major overkill, since I only have 2 HDD, DVD, MB, AUDIGY and GFX Card... lol)
What I've found is that there is an option for VoltMod on the PCI-X in the BIOS. I can't remember the exact Mod's, I'll edit this post once I've checked later[when I get home]) but I seem to remember there being
0.1V / 0.2V and 0.3V adjustment.

Now I'm comfortable with Overclocking, but have always shuddered a bit with the idea of soldering my 8-12layer motherboard with a home soldering kit, but hey, I know a lot of people do it - koodoz to you maties....

But seeing that I can Voltmod on my Motherboard in the BIOS, this sounds like something I'm willing to play with.

Is this a new feature that anyone has explored yet, I've not seen any posts anywhere?

What do you think?

Do you mean increase PCI-E frequency, if so stay away from it, it can cause random reboots and mabye kill your card Make sure it stays at 100MHz

if you mean raising the voltage on the PCI-E port. don't do this either.

two reasons:
1. dosn't give more overclockability
2. risk of frying either the port and/or the card.

600w PSU is not overkill in your case... CPU and especially the graphic card suck a lot of power.

and by the way... PCI-E is PCI express, PCI-X is 64 bit PCI ports used in servers
