Stats

 

Original Clock 3000 MHz

CPU Type Intel Pentium 4HT, 3600 MHz (3.75 x 960) FSB present speed. very stable

M/B Abit IC7-G Intel I75 chip set, lots of BIOS settings.

RAM 1024 Corsair TwinX 466 3700

Storage, 2x 80gig sata drives striped to raid 0, 1x 120gig WD

Video, Radeon 9800, flashed to Pro

Sony DVD burner

 

The radiator I purched for a wrecking yard $50

Zalman CPU water block which I did major surgery on $50

2 x 240v fans and relay switch from Jaycar $75, as the standard pc is 12v, the relay switch is needed & wired in to turn the 240v pump & fans on when you start or stop the computer as per normal.

Water pump 1500LpH from South Aust $80

Fittings from Bunning's $25

 

I have had it running at 3.75GHz & FSB 1004. What I'm aiming for is 4.00GHz with FSB set at 1000, but I have not worked out the voltage & ram timings so it will be stable. More research is needed.

The original Intel 3.00GHz temp was running at 50c idle, this water block has dropped the temp to about 44c idle. The water cooling does not show up until you load the machine, that's where it shines.

 

Question

When I go above 3.65ghz I hear 1 beep about every 3 or 4 seconds, it sounds like ram the pc will not load BIOS. How do I keep FSB below 1000 but increase cpu speed with the Abit IC7-G M/B.

There are some settings I do not quite understand.

The FSB is the only way to increase clock speeds on P4's. Try getting some PC4000 RAM. That should let you overclock further.

Also, if you think the problem is the ram, you can use the memory dividers to keep the memory speed within the proper range.

Changing the FSB:RAM divider can also cause the computer's performance to drop.
