how???

[mossopinc]

i have an athlon XP 1800+, a BN790TMoBo, (soz dont know the maker) a geforce 2 400MX, 256 of 133 sdram and windows XP. just what do i need to do to over clock it?????

[NeoStarO1]

well first of all if you don't know the manufacture of your motherboard I wouldn't be tampering with overclocking unless you know your system inside and out, hardware/software included.

I'd get more infomration about your system first before tampering with OC'ing. Just my opionion, and I think the same will be said from others since you stated don't know the maker.

Do some research before doing this. Also note that once you OC your computer you automatically void any warrenties you have.

I can't help out with the finer points of OC'ing but I can see more research on your part is needed.

WHY do you want to o'clock would be my question. That CPU should be fast enough for most jobs.

Maybe some more info on what you hope to achieve. Many ppl assume o'clocking means everything will go faster. This is not necessarily true.

Maybe jameswillamor will honour us with an opinion in here?

well thats why i was asking NeoStarO1. i just want to do it just long enough to run 3dmark 2001 im wanting to see what the difference is between my cpu and a faster one cos im going to build a new computer and can only aford the 1900+ and i want a rough idea what that cpu is like before i do it, im trying to get it together for an xmas pressie oh and stuff my warrenty who cares, ill just buy my duel MoBo ive wanted after xmas if it brakes

[mossopinc]

oh and its a lex Mobo dont know how i never remembered that DOH

[NeoStarO1]

Asking me? I only responded to your thread LOL, I didn't see my name in it specifically asking me.

IMO its not worth it to OC just for a bench mark, but then again that is me and I don't OC. Others will be along when they can and advise you if you really honestly don't care about the potential damage that can be done.

Overclocking your processor isnt really going to make much of a difference to your 3dmark. 3dmark is more determined on your video card. The difference between your video card on a 1800 running at 1900 speeds will be like, maybe 20 3dmarks if your lucky :P

Greater improvements will be seen in your motherboard selection. I would save your money on a XP 1900+ and get a mother board that can run a 266fsb to the ram. Your 3dmark should go up considerably esp. with 512 mb of DDR running @ 266mhz. But as to how to OC at start up get into your bios and look for cpu settings/ multipliers. (if your mobo bios is so equipt) change the setting on the multipliers up. Should be set @ 133 x 11.5 giving you a cpu running @ 1529 or so. That is standard for a 1800+ now if you jump that to a x 12 multiplier you will have succeeded in OC'ing test each config of the multiplier for system stability. If your bios so enables you, you can also change the Mhz. once again step it up to 134 and so on checking the config for system stability. Several things to keep in mind. 1 you need to keep your cpu cool. So dont skimp out on a HS and fan. 2. Learn where your cmos clear connection is most mobos will only let the processor get OC'd so far then the sys will shut down. clear the cmos and start from the last know good config.

Good Luck

BTW I had done a lot of research in this area before I started. In the last 2 Years I have burned 3 processors up from OC'ing so deep pockets are needed. There is no good way to OC unless you just go out and buy the top of the line.

Just to point out, you won't be able to change the multiplier without modding your CPU, you may be able to change the fsb though (what the multiplier is multiplied by)
This might also be accomplished with DIP switches on the mobo.

The difference between the 1800 and 1900 would not be that much, really. The O/C that really makes the difference is the FSB and how it plays with the ram. Mechanymagazine hit the nail on the head about the video card. There's where you would see the greatest increase.

If I wanted a faster all around system, I'd keep your existing cpu and upgrade the motherboard and ram to a DDR 266 or higher based MB. For less than $200 (US) you can get a really good MB and RAM that will make your machine scream...

But to really see a big difference on the benchmarks with what you have, grab yourself a new GeForce4 Ti-4200. You can get an ASUS or MSI on NewEgg.com for less than $150 that will be a HUGE difference on benchmarks. (My MSI was $132 shipped to the door, by Bro-in-laws ASUS was $148 FedEx overnight to the door) Here's a nice looking one for $133 shipped to you:

Depending on what chipset is on your current MB, you may not get a huge increase in speed with a FSB increase, if you can get one at all. My KT7A RAID is lucky to get an additional 10 FSB before it starts to crap out during benchmarks. I run it with an additional 3 on the fsb and upped the multiplier by 100 mhz (modded chip) but the score just wasn't that much more.

Tinkering with my bro-in-laws KR7A RAID, I didn't mod his XP 1600 but I upped his FSB from 133 (266 DDR) to 145 (290 DDR) and clocked his video card from 250/512 core to 270/590 o/c and gained about 1200 on the overall score. I didn't notice much difference in speed, visually. It was a HUGE improvement over his GeForce2MX PCI card, however. The first score on 3DMark was 375... pathetic. With the GF4, he went up to 8800, stock.

What kind of computing are you doing? If you can let us know where you want to see the best performance, we can help you a bit better. Hope this helps.
