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?nam...
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?
September 13, 2003 4:57:15 PM

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
September 14, 2003 5:12:33 PM

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.

scotchen I don't know which number on memory timings is for which option in the bios
September 15, 2003 12:42:21 AM

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?
September 15, 2003 1:26:51 AM

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.

thanks guys for helping :D 

two more things :o 
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?
September 15, 2003 9:36:43 AM

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 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.
September 16, 2003 2:46:02 PM

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?

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

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.

Hi there
I'm thinking of buying a XP2500+ (Barton), (XP2600+ TBred / P4C 2.4 are my other 2 choices), any way. Which MOBOS can support the changing of the cpu multiplyer because I want to (if I get a 2500+) make it run at 200x10+2000MHz.

My MOBO will be a Gigabyte or MSI or Asus. So how do I find out which does support a multiplier changing option, and do I have to "UNLOCK" the CPU like in the THG video (with the glue and the tape and the scraping and the chance of damage) or can I just pop the CPU in and let the MOBO do the rest.

Also what do you guys recomend for a resonably priced PC,
1)Overclocked: XP2500+ or XP2600+ or P4C 2.4
2)Stockspeeds: XP2500+ or XP2600+ or P4C 2.4

Please tell my which is best of group 1) and then group 2).

Oh wait Grahix: FX5600 ultra or non-ultra or 9500 Pro or non-Pro of 9600 Pro or non-Pro: Which is best.

Last thing , If I get an Athlon and run it at stock speeds,
like FSB333 , is there any point in spending so much money on 2x256MB DDR400 for dual setup instead of the cheaper 2x256MB DDR333 for Dual setup. Does the price difference between DDR400 and DDR333 justfy the performance gain (is there even a performance gain - if so how much).

So many questions so litte time.
Somebody kill me to end this madness (just kidding)

Thanks to everybody who will reply.

The Barton is probably the fastest of the three at stock speeds. The P4 has enormous potential in the right setup. The TBred is cheap and does well for the money. Look into ATI video for high end cards. They are currently ahead of Nvidia in the DX9 race. If you run your AMD CPU at stock speed 333 is enough, but if you check pricewatch.com (you're welcome) you'll find that there is no difference in price between 333 Mhz and 400Mhz ---PC 3200 has come down recently.
September 19, 2003 9:39:48 PM

Actually the 2.4C is faster by default and it's an overclocking monster.

Get the A7N8X-D mobo if you go to AMD, great overclocking board and has the n-force 2 chipset. P4 boards i cant help you with, ive never looked into them!

Ide choose the ATI 9600 PRO or even go up to 9700 or 9800.

Corsair XMS pc3200 400mhz isnt really that expensive now, i paid 128$ I think for a matched 256x2 pack about 2 months ago. Its probably cheaper now!

I got my barton 2500+ to 3200+ speeds, but i turned them back down untill i get a new HS+F.

Good luck on your new pc buy!

I found that 1.775v was the lowest i could go running at 200mhz fsb, might try that if you have suffecient cooling
