SOunds like RAM or CPU not taking it. I'm no Intel guy (they'll be along soon ) but from what I've read "b's" overclock the worst. 2.4GHz->2.8GHz=133GHz->155Ghz(DDR310). I would guess either your timings are tight on loose timing Ram/need more voltage OR your CPU is too hot/perhaps need alittle more voltage.

Hope that helps alittle.

it means the pc is unstable my bets on the cpu, the ram is not being stressed all that much at that speed, how much vcore have you given the chip?

From my newbie experience of overclocking when i get this error is the CPU that is limiting the overclock.

I've gotten a P95 error on the blend test, which stresses both RAM and CPU, on my family computer (XP2400 at stock) because the RAM is craptacular.

What test are you running?

Keep in mind also that P95 is an _extreme_ test.

It's not your CPU. It's your memory!
Your samsung pc2700 won't run at 195FSB.
Either get some pc3200 or higher rated memory, or set the
divider to 1:1 instead of 4:5
99% of 2.4b can run 2.8GHz without any problem if you have proper memory and motherboard.

If EVERYTHING is showing fatal error, including torture tests that are mostly run from the CPU's caches, then it is most likely a CPU problem.

My samsung PC2700 will run over 200 FSB stable with a voltage boost. His RAM might be able to take it. Try testing with memtest86 (all tests). IF it fails that, it's probably the RAM. Try running with a bigger divider (ie run the ram slower) and see if the problem goes away.

Right, but lowering the FSB speed also lowers your CPU speed, and so doesn't locate the error. How did memtest86 go?

do as linlibj suggested put your divider as 1:1 or under DRAM Freq. its gonna be listed as 400..that will put you at 1:1 with the FSB @ 156 your mem will be at 312MHz so u def shouldnt have any problems if you do this!!!

probably is the memory not being able to take it. fair enough wanking on about how well ur memory runs above its speed guys but not all dimms will and even so slight levels will occur and some systems will pick up on this more, specificaly more with p4 im guessing due to quadra band bus speed. either way running that kinda memory on a p4 is asking for issues really, and running stock speeds is basicaly running your memory overclocked to near end of its potential.
