Why can’t i run my xp 2800 at the correct speed???? Help!!!!

I have a non Barton Xp2800, running on a AsRock K7V88 MoBo, with 1024
MB Samsung Pc3200 ram, GeForce 4200ti 8x AGP graphics card.

My computer refuses to run at is correct speed of 2250 mhz (13.5 x
166) and crashes as soon as windows starts to boot up. The highest i
can run it at stabily at is (13.5 x 150). My first thoughts were that
heat was preventing it running but i have installed a Copper Lite
heatsink and fan from Arctic Cooling which supports up to Xp3200, so i
thought it would cope great with a Xp2800. I have 2 case fans, one
extracting and one circulating the air. The case temp is about 24-27
degrees. The CPU monitor in the Bios shows about 40 degrees idle.

Any suggestions??????

Did you increase vcore a little? Try 1.70v. Is this really a 2800+ XP
Tbred? Don't use Windows to test it. Get a memtest boot diskette or cd. Is
the ram running a default timings or did you change them? that new cooler
is only marginally better than the original, and it may not cool enough
under load with a raised vcore. If you can exchange it, go for a TR2-M1 or
-M3. I assume you have at least a 300W PSU.

is this a brand new build? what does the vcore, 3.3, 5 & 12v rails
read in the bios?

is your 2800 the 1.65 or the low voltage 1.5 version?

have you tried setting the memory to spd?

I have tried raising the Vcore 5% and my power supply is 500W, so
should be no problem at all. I have not tinkered with anything else
in the Bios as although i am capable of putting a system together, my
knowledge is not that great. I would flash the Bios and put the
latest version on, but chances are i’d screw that up and waste my
motherboard!
