Need Help Overclocking PIII 800EB on ABIT SE6

[pel64006]

New to the Forum. I hear there are a lot of good helpers here. I am trying to overclock an 800EB on an ABIT se6. I can get 140mhz fsb (4:4:1) ok. 145 and 150 have to set to (4:3:1). Serious degrade in performance there. When set to 4:4:1 above 140 I get a Windows protection error. Is there a way around this ? Video is Annihilator Pro, Memory is 256 mb. core voltage is 1.75 and stable. Temp is ok. Looking to cool it better though. Need different fans. Any help would be appreciated and thanks

Sounds like an SDRAM issue. Generic CAS3 PC133 doesn't do well over 140 MHz. Get some CAS2 PC133, either Mosel Vitalic (from Mushkin, Memman or KD Computers), Crucial, or Corsair.

If you already have decent SDRAM, you need to set it at CAS3 to run at 150 MHz.

Just yesterday I tried lowering my core volts and got a protection error...so if you have good enough cooling, I suggest raising your core volts to like 1.8, and maybe 1.85.
Should finish booting then
I forgot to say...Welcome to the forum

Pel,

Several of us on this board believe that the SE6 is not very stable above 137 FSB. Batboy came to this conclusion and changed boards (I think he sold his SE6).

I still have my SE6 but since I have only a cB0 chip I can't expect miracles. I have had my PIII700 running up to 980 MHz with extreme (outdoor wintertime) cooling.

Good luck in your overclocking.

I don't think you need to worry about raising voltage. Maybe raise it to burn it in and lower it again. I have mine set to 1.75 voltage around 160fsb with no problems and from what I have seen from others like Friday 150fsb with 1.75 voltage on this chip is easiely obtained. My guess, either the ram or board as was suggested. If you can, set the ram to pc100 in bios and see if it boots then. If you can't do that lower the fsb to where you can just barely sneak into windows and try benchmarking the ram with Sanra. If that works then try the cpu. If both pass loops with no problem its probably the board.
