A newbie's guide to Overclocking a Athlon XP CPU
- Status
arre mask u have one of the the best ocing athlon ever - 2500 barton..y r u complaining????..i think u can easily go higher than 2225 mhz by lowering the fsb n increasing the multiplier...forget the shit about higher fsb=higher overall speed....185x12.5=2312 is definitely faster than 200x11=2200...check it out in any benchmark...sisoft..pifast..pcmark..
hey mask do u use both ur ram dimms while ocing??...ie (i think u have 256x2 ddr500??...really envy u man!!)...just use one 256mb dimm.....cause i have heard of cases where dual channel really drags down the oc....i do the same thing...just one 512 ddr400
btw i forgot to mention a very imp. thing....the oc i have achieved (2312mhz) is with just 1.55 vcore ...
...n tested with 12 hrs prime95...so the best is yet to come... ...

...n tested with 12 hrs prime95...so the best is yet to come... ...Well pal.. 2225MHz is the limit of my Barton. 222x10 or 202x11 or 185x12... thats the best the chip can do.
Yep, i have 2x256MB set-up in Dual Channel. I know Dual Channel is very demanding, but i want to use it too... so i have never tried OCing without Dual Channel
And 2312MHz at Vcore=1.55V is very sweet
Many Congratulations!!! Take that baby to the limit and do keep us informed

yea, the normal voltage should be around 1.65v and after o'cing it will increase or should be increased to 1.8 or so. i have tried o'cing my xp1700+ and after o'cing to 1.6ghz voltage was 1.8v.
my 1800 is a dlt3c...so 2312mhz with just a .05 increase in vcore is easily possible :roll: :roll: ....n i am using it for the last 1-2 weeks without a single bsod...ppl have touched 2.5ghz on 1.6 vcore with this beauty
n i had tested it with 12 hrs of prime95...temps shot upto 51c..
and what i meant about higher fsb not equal to higher overall speed was that when the diff between the fsb is small but the speed diff. is higher,only then does this apply.eg.185x12.5=2312 is definitely faster than 200x11=2200 cause diff between fsbs is just 15mhz, but diff between clock speeds is 112mhz....so in such a situ. 185x12.5 is definitely faster when its gonna be 200x10=2000 n 166x12=1992 then the 200 fsb will be surely faster...got it??
hoped this clears up ur doubts darklord??
and as for u crusader77, if u have to up ur vcore to 1.8v just to get a oc of 150mhz......dude u better forget ocing...n wtf do u mean by normal voltage=1.65v??my cpu is a dLt3c...if u know anything abt steppings the L in the DLT3C is supposed to indicate a stock vcore of 1.5V, DUT3C indicates 1.6v n DKV3D indicates a vcore of 1.65v n 333mhz fsb...get ur basics clear before u go around making posts:roll: :roll: :roll:

Can you please explain on what basis you can say so? :roll:
That really is very good but according to me it is highly unlikely since it is an AMD chip. :roll:
Could you please clarify this?

that voltage is normal for xp1700+ and also the xp2000+.and the increase in voltage was correct acc. to the cpu. now whether it is dlt3c or not i didnt know.i was just not sure like others ,how ur voltage was so low.
thanks for clearing it up Apollyon.

i understand whatu r saying,,but my bios shows 1.65v. there is a diff. of 0.5 v. i dont know why but thats what my bios is showing and when i overclock, it is 1.8v. 
also check out this info i got on a site:-

OK>> i have been trying for the past hour to find a link to post the OPN codes (for Vcore), but i havent found any yet... so i'll give it to u here!
Supposin the CPU is a DLT3C - L defines 1.5V
Instead of the L if its the following letter, it corrrespondingly defines the voltages given!
Y - 1.10V
C - 1.15V
T - 1.20V
X - 1.25V
W - 1.30V
J - 1.35V
V - 1.40V
Q- 1.45V
L - 1.50V

U - 1.60V
K - 1.65V
P - 1.70V
M - 1.75V

i increase it to 1.8v ,as thats the recommended overclock voltage for my xp1700+. i am not a 'pro' overclocker and am new to o'cing my processor..(i have overclocked my gfx card before quite a few times though..).

yea ur right! i did notice a rise in temp. when i o'cd the first time.it normally is around 45-48 deg C, but after o'c it was about 50-55 deg C,,but that is still ok and not near the danger limit. i think it is a thoroughbred,,,its definately not palamino. 
and also, can u tell me what my fan rpm should be for both cabinate and cpu fans.(my current cpu fan rpm is about 4500-4900 rpm). and when i o'c and play a game or so,, and then check my voltage it increases automatically to 1.84v. is that ok?

Most of the mobos over-volt the CPU. That means to say they supply about 0.05V more than what u have set it to. In my ASUS board, when i set it to 1.7V, i get around 1.75V. So its ok to see that increase. And also, the Vcore doesnt stay stable. it usually fluctuates in the range of 0.05V.
The CPU fan speed depends on the HSF itself. Long back AMD CPUs acame bundled with 6000 rpm fans. now-a-days almost all of them (my 1700+ and Barton 2500+) come with 2500rpm fans. It doesnt matter much how fast the fan is running, but what matters is how cool the HSF is keeping the CPU. The latest bundled HSF are all light-weight desing helping in better cooling compared to the older heavier HSFs.
And about ur CPU, may be its a T-bred A core one. Or its just that u r unlucky with a poor OCing T-bred B core! like me!
