Overclocking help

[thelanx]

I'm kinda new to cpu overclocking. I was overclocking a celeron 2 GHz 100fsb to 133 fsb thus 2.668 GHz. I ran Prime95 and after about 30 min I get an error. My ram is 256 mb Samsung PC2100 CL 2.5 at 3-3-7. I changed the timings from a default 3-3-6. I don't want to clock the processor down since my pci/agp isn't locked and it's at 33 at 133 fsb. Can I and how should I change the timings on my ram? Right now I put the timings back to 3-3-6 and Prime95 is running fine so far... Also I'm using mbm5 and my cpu temp is 53 at full load. Is that normal? Thanks!

Yes, your temps are fine, and of course you had to raise (loosen, make slower) your ram timings, you're running PC2100 ram at PC2700 speeds! Hey, as long as it's stable, you got yourself nearly 700mhz of free performance.

Well, I wasn't clear, but my fsb is 133, and my ram is running at DDR 133, so that's PC2100 specs right? I just upgraded to 512 mb samsung ram, cl 2.5. I still get errors in prime95 at 2.668 GHz once every 45 min or so. Should I relax the ram timings? They are at spec and should be able to do more, so I'm not sure if that will help.

No, if you're running your ram at it's rated speed, it isn't your ram giving you errors, it's your cpu-- because you aren't giving it enough voltage.
