Athlon Xp 2100+ OCing help

Youre cpu the 0304 is an older unlocked Tbred, so youre lucky, the week's 0340 and above are locked, ?(thier Multies i mean)

You should be able to overclock alot then this, Raise the vcore to 1.85v, with the stock HSF you shuld be able to reach like 2200 mhz, you raise or lower the multi.

You have some pc2700 ram, do this before u do anything first. Lower the cpu multi to its lowest, Like 9 or something , then raise the RAM FSB to 166 (also raise the memory voltage to its max witch is like 2.8 or 2.9 on most boads.) After you raise the meory voltage then raise the fsb to 170, if it boots into windows and everything seems to run fine, try 175, then 180 and so on, Once youre computer gets error's or is instable or doesnt boot , Lower it back down by 5.

After you find out youre highest Possible FSB speed with youre memory, then you gradually raise the cpu Multi to like 8 or 9 or 10. Here say if u got 180fsb max on youre memory, then raise the cpu multi to 11, 11x180= 1980mhz, if it runs fine, then go to 12x180, 12x180=2160mhz, Dont forget to keep the cpu voltage @ 1.85v, After that if its stable in windows and prime95 for at least 30 minutes, raise the multi to 12.5x180=2250mhz (if u have that option) If you dont have 12.5 try 13x180.

Im using 180 as my Basis, you may or may not get 180fsb Just try what i said above first to see how far ur memory will go, then start to overclock the cpu.

i got my 2100 to run at 2156mhz without rly spending any time on it
154fsb/ 14 multi

of course i dont use that cpu now that i got my A64 3200
any one wanna buy it w/ gigabyte board?

Thank you guys!

CandymanCan, your reply was most helpfull to me.

After clearing my CMOS for like 10 times, ive succesfully booted to windows, here's what ive got:

DRAM 2.7V (Max)
VCore 1.800V (Max)
CPU Multi x9 (7min-13max)
CPU FSB 133mhz
FSB/RAM Ratio 3:4
RAM FSB 178mhz (it wont let me manually enter numbers, only set by Ratios like 1:1, 3:4, etc or set it on Auto) The max my ram would go was up to 178mhz, after it PC wouldnt boot.


but very wierd thing is that SPUZ reads my Multi as 17. Check it out:

Ok. Is that Crucial ram, btw? I had 1x512mb pc2700 that would do almost 180 FSB even without a voltage tweak. That RAM is rated to do 166. Anything more is an overclock. You might need to up mem volts to maybe 2.70v. Also, with an Nforce2 board running dual channel (more than one stick of memory) try 3.0-4-4-11 for your memory timings for now. Might even be able to tighten those later. And no reason you shouldn't be able to run the mem in sync (1:1).

You're doing fine. Go back to at least 166FSB, get the memory in sync for now, and go from there. FYI-CPU was made two weeks after my 2100 (see sig).

How long did Prime95 run before you got an error?
