Overclock Help

I'm curently in the progress of overclocking a friends server.

It started as a 3000+ Venice 200 x 9 = 1800mhz @1.4v

I'm now posting this message at 275 x 9 = 2475mhz @1.520v. It's set to be 1.550v but I guess the PSU isn't too brill, considering the BIOS has a 1.525v setting as well and it's lower/nearer that

The memory is on a divider (CPU/11) at 225mhz at 2.8v

The one problem is that it keeps failing Prime95's Blend Tortue test.

I managed to get into windows at 2700mhz (not bad from 1800) with the motherboard at 300 FSB (high as it went

) RAM Divider at 2700/14=192mhz and the HT at 300*3=900mhz.

I wanted 311 FSB, 311*9=2799
2799/14=199.9mhz RAM (3,3,3,8 if it's running at 200mhz it shouldn't need looser timings?)
and 311*3=933mhz HT.

The CPU and RAM are both set at the max voltage they can be and the CPU runs at 40C at full load.
The HT shouldn't need more voltage because it's running slower than intended. However the chipset could probably use a boost considering it's at 300 rather than 200. Problem is though the heatsink has the smallest surface area I've ever seen and a normal small NB fan so the fan is having little effect because the heat is pretty much all in the chip. So I'm wary of pushing any extra volts through it especially combined with the huge FSB increase. I wish it were as simple as getting a new NB heatsink and fan but it's right at the end of the PCIe graphics card which clears the heatsink and fan by about 1.5mm :'(

I think the chipset is getting to hot which is cause the instability, but I'm really at a loss cause of the graphics card.

I had to let him take it away at stock for now as it turns out one of the 512 DIMMS was kaput.

Yep it's pretty damn hot at stock speed and volt

It's a Foxconn WinFast something with nForce4 Ultra

Yes I realise. I think it's the chipset overheating that is very difficult to do anything about though looking around the forum I've seen a Jing Ting Force Chipset Cooler and am waiting for the new revision when it comes around
