Ok this is weird. I had an Athlon XP 1700+ on my comp but it only ran at 1093 MHz, instead of 1.43 GHz or however it's supposed to run. So I took an Athlon XP 1800+ from a virused-up comp I had and switched processors but it only ran at 1150 MHz (On the virused-up computer it ran much faster--somewhere around 1.5 GHz). Help me out, MY COMPUTER'S MESSED UP!

Full system specs please. Also the bios settings being used, ram timings, brand and wattage PSU. My best guess with no data to work with is that you have a power, cooling, or bios config problem.

I'm not sure but I think that your system may be under powered I worked with some systems that would not run stable with their 1700+ so I had to decrease the external frequency of the processor which decreased the speed in mhz to get it to run stable. It turned out that the mobo cpu combo either needed 325 or 350 watts min to run. Since you have a 300 watt PSU that might be your problem, I'm not positive though. What kind of motherboard are you using? this item may be critical

like i said before, im not at my comp--even if i was i dont know how to know the mainboard type thing and i think ur wrong about the power supple cuz my old virused-up comp had like 275w but it is the one that ran the 1800 at like 1.5 ghz.

Is it because your FSB is at 100MHz instead of 133MHz, or is it that the CPU isn't stable at faster speeds?

Good catch! I presumed he was attempting to overclock and this was the issue but I think you just nailed :)

im not at my comp now and im not in the vicinity of my comp now and i havent memorized every spec. of every componet of my comp and etc. anyway, i dont think that the same unstability would happen to two processors especially when one worked fine on a weaker comp.

I had the same problem with a system i built and all i needed to do was change the fsb to 133.

not to be mean or anything, but FOR GODS SAKE IM NOT GOOD WITH COMPUTERS AND I DONT EVEN KNOW WHAT OVERCLOCKING IS!!!! and how the hell do you change whatever the hell an fsb is to 133mhz? HELL HELL HELL HELLP ME IN A LESS TECHNICAL WAY IF POSSIBLE LIKE BY TELLING ME WHERE TO GO TO CHANGE SETTINGS, OR SOMETHING THAT IS ACTUALLY USEFUL TO ME!!!!

please dont hate me.

If you told us what model motherboard you were using, we could at least tell you whether you would have to change a jumper or a BIOS option, possibly even exactly where said jumper is.

If it's a BIOS option, the way to get to it is usually by hitting delete while POSTing, then enter the top left option (called CPU Soft Menu on my motherboard). There should be an option for FSB or host speed there. Set it to 133MHz, hit escape, then choose "save and exit" on the main BIOS screen. When you reboot, the CPU should be running at its full speed.

If it's a jumper option, it could pretty much be anywhere on the board and you'd have to look in the manual for it.

well, its kind of a long story, but i dont know jack about my computer because i never had a chance to look at it--its custom built, and again, a long story so i dont know the maker and no one does. so if there is a way in windows where you can find out the mainboard then thats great. i'll try the bios thing. wait--do i press delete while the computer is doing that thing when it turns on and it takes me to that place where i can change the cmos settings? and please explain what a jumper is, and how to change that.

You could try downloading the Belarc advisor (http://www.belarc.com/free_download.html). It showed me the manufacturer and model of my motherboard.

To "do the BIOS thing", it can vary but on most motherboards you just hit delete shortly after you turn it on, like you said. Be careful what you change; if you start changing voltages randomly things can get broken.

A jumper is a small plastic bit with metal inside that's used to connect two pins. Usually in locations that are jumpered there will be three or more pins, with the idea that you've got two connected at any one time. To change it, you just turn the computer off, move the plastic, and turn it back on.

thanks! im not going to be at my computer at home for about an hour but when i do ill give you my system info. so when im changing the thing in bios i just go to some type of cpu setting option and tune the fsb to as high as it will go. and also, will i need a new heatsink or fan or anything (will my processor overheat at higher settings?)? Thanx!!
PS: this is kinda random but my video card sux so im changing it im getting the new card in the mail tomorrow (i know it'll work cuz its an agp 2x/4x and i have a tnt2 which is 2x) but it's a VisionTek Xtasy 9100 128mb AGP card and i got it for $50 ($50 after the mail in rebate) brand new. is this a good deal?
PSS: TnT2s are for suxors
wow this website is helpful.

when its booting up, keep hitting "delete" until you get to a blue screen.

i think in "advanced chipset features" tab, you have the option to change your FSB to 100, 133, maybe 166, and maybe 200.

change it to 133.

save and exit

Do you have your motherboard's manual? Or call the guy who built it for you; he should have it.

Some motherboards have a tiny jumper that you have to move from one pin to another along a set of three to set them to a different front side bus (in your case, we suspect from 100 to 133). In others, you can do as suggested above by entering the bios and i believe it's under advanced features.

However do as suggested above and run belarc to find your motherboard. If you don't have the manual, you can almost always access it from the motherboard manufacturer's site - example, abit, ecs, asus, gigabyte.

If you don't know the motherboard site's address google search.

Please don't yell at the guys here, they teach us really well.

Good luck!

Ok this post is gonna be like, hella long.

Last night I was foolish enough to go strait to BIOS without consulting you guys first with my mainboard model. I went to the CPU PnP Setup and under CPU Speed it said: 100/100MHz. I didn't know what that had to do with the FSB, but being foolish, I set it to the highest setting: 166/133MHz. I saved the settings and quit. The computer restarted, but nothing went on the monitor, and the keyboard and mouse didn't have any flashing lights. Then I got this brilliant idea: Why not just put the hard drive and processor from this computer to my virused-up computer? So I put in the hard drive and processor, being careful to put everything where it was at first (marking cables) and so then I started up the ex-virused-up computer. Then I got this message that said that there was an error and Windows was shut down to prevent PC damage. I kept restarting the comp and kept getting the same message. So I said to myself: This is a piece of crap computer. I know! I'll just set the processor settings low on this computer and put the hard drive and processor back on the first computer. Unfortunately, there was no processor setting on the computer, which totally pissed me off. So then I went to Plan B, which was to take the Athlon XP 1700+ I had (I was talking about the 1800+ when I said "processor" before) and put it back in the first computer. Now I'm back to the same 1.1 GHz piece of crap. I just found my mainboard manual. It does not say anything about a maximum setting, but I will tell you guys that it is an ECS Elitegroup K7S5A PRO Socket A Mainboard. Now I have this question: Since I have to live with my 1700+ instead of my 1800+ (not a big deal) what should I set my speed to (XXX/XXX MHz)? Thanks!

P.S. I won't be foolish again.

I don't know why you think you can't use your XP1800... but... it should be 133/133.

By the way... I sensed a little rudeness/impatience/hostility because people weren't reading your mind, or that they didn't know what type of hardware you have even though you don't... you might wanna loose that attitude if you ever expect to get some useful help around here.

im afraid to try 133/133mhz because if my comp blacks out again, i have nothing to use. are you absolutely sure? and why did my comp black out in the first place?

LOL how come no-one managed to get this on the first few replies? its one of the most commonly asked questions

1466/133 = 11
therefore 11*100 = 1100

1093 is close enough which = it was running 100fsb
