How to OC My 2500+ Barton?

[spherific]

Ok I'm building my first computer. I have a vantec aeroflow, amd athlon xp 2500+, corsair xms pc3200 x2 256 mb ram, and a7n8x deluxe motherboard. What should I do to overclock this to a amd athlon xp 3200+? Thanks for your help guys.

Go in the advanced section in your bios and increase the FSB from 166 to 200.

I have pretty much the EXACT same setup as you... heres a link to my other post:
http://forumz.tomshardware.com/hardware/modules.php?name=Forums&file=viewtopic&p=671338#671338
go into yoru bios, and turn your multiplier to 10x. if its grayed out go to the option above it and change it to "user defined"

After lowering the multiplier change the FSB to 200. Run prime95 all night and a day and see if u get any errors. If you dont turn the multiplier to 10.5x and do it again. Do this so on and so on untill u get back to 11 or 11.5 if your lucky!

With stock coolign i woudltn suggest changing yoru Volatage! But its an option...

I curently have my 2500+barton running at 3000+ speeds! (2.09 Ghz)and thats only with the multiplier at 10.5x!

hey thanks, i just got a few questions, where do i get prime95? and if I stick my 2 memory sticks into the 2 blue slots on the a7n8x deluxe it is dual channel right?

 

[DOHCrazy]

Search google for Prime95 (oneword)

Yes, if u put the memory in a black and a blue you wont boot up! But yes, the 2 blue slots are the dual channel!

Another thing... While your OC'ing if ur system wont boot up, move the blue jumper over (while its off) and then move it back and turn it on. You can fidn which jumper this is in your manuall. Its called clearign the cmos.

Good luck man and take your time!

A7N8X refreshes bios whenever there's an overclocking failure. However if you clock your memory too high, or put it in timings that's too tight for it. Sometimes it won't refresh and just makes weird buzzing sounds, that's when u gotta clear cmos.

hey thx guys, i have some more questions, my memory timings on the corsair website say 2-3-3-6-T1, so in the bios what am I suppose to set to get those timings. And when I set the cpu external frequency its doubled what it says right?
The resulting frequency for my memory says 200 mhz, does that mean it is 400 mhz? Says that in post also

 

[scottchen]

Go in the advanced section in your bios, change everything to user defined, and then you can change the memory timings to whatever you like. And then you can also adjust the FSB by 1.

[spherific]

scotchen I don't know which number on memory timings is for which option in the bios

 

[speeduk]

Look for CAS. Set that to 2. Next is T(RCD) and T(RP) set these to 3 and finally set T(RAS) to 10. Trust me that 10 is faster than 6 or 5 on nforce 2 motherboards. Even though some will say different...

can u explain how memory timing works.. and should i change it with my barton clocked at 200x11.5? a link to another post woudl be fine to, w/e works for you. Thanks in advance!

so speeduk would, SDRam Active Precharge Delay - 10, SDRam Ras to Cas Delay - 3, SDRam RAS Precharge Delay - 3, and SDRam Cas Latency - 2.5 be good?

Oh and am I suppose to lock the AGP fsb, if so how would i do this?

 

[scottchen]

If you could change it to 11 would be better. the rest of the timings are excellent, if you want to lock the AGP there's a option in the advanced section called AGP frequency just set it to 66.

[spherific]

thanks guys for helping

two more things
if CPU External Frequency (FSB right) is 200mzh, it'll result to 400 mhz? And for memory if it says resulting frequency is 200 mhz, i turns out to be 400mhz?

 

[speeduk]

I tried 11 but it was slower, by a lot! Heres what I figured:

Cas 3,3,3 needs 12
Cas 2.5,3,3 needs 11 or maybe 12
Cas 2,3,3 needs 10

speeduk, on that link to that other forum, what program are they using to get those memory timings?

Well speed he did say 2.5-3-3-so i guess 11 would be best.

[speeduk]

Probably bios to get memory timings, and sandra as a bench to see what diff the timings make... And don't forget this is for nforce 2 mobos only....

speeduk im using 2.5,3,3,11 on corsair xms 2x 256 mb pc3200, that good? Also i'm suppose to double the frequency to get the resulting frequency. Like in the bios if resulting frequency for memory is 200mhz, then it'll be 400, and cpu frequency is 166, it'll be 333? Right. Also how do I test my memory to see what timings are better.

k, the actual speed of your ram is 200mhz, or 166mhz, but ddr can move to bits of data every clock cycle, as compared to sd ram which can only move one. So for marketing purposes the ram is called ddr 400, but its actual speed is only 200mhz

hey, I ran prime95 at 1.725 volts, after like 4 hours I got FATAL ERROR: Resulting Sum was "Some Big #"; Expected "some big #". What should I do?

 

[scottchen]

More voltage.

yo, where do I go to overclock my ati radeon 9800 pro

 

[scottchen]

You mean how to overclock your 9800pro? there's the Omega Drivers which you can get <A HREF="http://www.driverheaven.net/downloads/index4.htm" target="_new">here</A> After installing it in your advanced display properties there will be an option for you to change the clock speed of your card.
