ok i have a amd k6-2 400mhz 100mhzfsb 4.0x multiplyer and when using the cpu at 400mhz windows xp just starts to load and then restarts but if i underclock the cpu to 366mhz it works fine WHY? ram is 2 128 pc133 7200 rpm 40gb hdd YES 40GB NOT 40MB 50x cd-rom 6x cd-rwdrive writes at 2x rewrites at 1x

x86-586,

1° Did you flashed your BIOS?

2° Do you mean, when you increase the fsb higher of 200Mhz Win xp don't boot?
>> If you don't have memory sticks of 400Mhz (PC3200) you can't go higher than 200 fsb because they don't support that speed!
3°Why do you write, 40GB NOT 40MB? Man that's not a big deal, 40GB are certanlly anogth to your PC but is not incredible ...
4° You can't reach the speed of a "Lambugini"
with little "Mazda", you have to upgrade your hardwares!

Alot of AMDK6-2 cpu's read a 2.0x multiplier as a 6.0x. If you want you could overclock you CPU to as fast as 600Mhz. If you like set you fsb one lower than 100Mhz, 83.3Mhz I think it is and set you multiplier to 2.0x and you should get a speed of 500Mhz. Or keep changing your settings till you get a happy speed with no window errors or restarts. I had a AMDK6-2 500Mhz a while ago and I had the same problem with win98 until I found out that AMDK6-2 see a 2.0x multi as a 6.0x multi and I set my cpu settings to 83.3Mhz x 6.0x witch gives you 500Mhz. Your mobo might not like running at 100Mhz fsb like mine didnt.

Good Luck

Matt.

What motherboard do you have? What's your CPU voltage set at? It should be 2.2v, possibly 2.4v depending on the CPU. The voltage is printed on the top. Obviously, it should run at 4 x 100mhz. Check all your BIOS settings...make sure your memory settings aren't too aggressive.

on in responce 1

1 yes i did flash my bios

2 the fsb was not 200 it was 66 and i upgraded with a mobo with a mad 300mhz 66fsb and put a amd 400mhz with a 100 fsb

3 because most people say 40gg thats not even posable

and

4 ok now to bad o dont have ether car

responce 2
i dident know that but the every body i know sas that a mobo locked at 100mhz-550mhz cpu not fsb even with overcloking or not but thanks for the info

tha mobo 5mvp3 this mobo has 3 isa 1 agp 2x and 3 pci and does any one know who made the power tx mobo with a amp9600 model #

Is this your board?

Forgot to ask...when you upgraded the CPU, did you change the jumpers from 4.5 x 66mhz (300mhz) to 4.0 x 100mhz (400mhz)? CPU voltage set to 2.2v? Did you experiment with other multiplier/FSB settings?

2.0 x 66mhz = 400mhz
5.0 x 75mhz = 375mhz
5.5 x 75mhz = 412.5mhz
4.5 x 83mhz = 373.5mhz
5.0 x 83mhz = 415mhz
4.0 x 95mhz = 380mhz
4.5 x 95mhz = 427.5mhz

What type memory are you running? You'd definietly need PC100 or PC133 to be able to run the FSB at 83, 95, or 100mhz.

Oooops...one last comment. After looking at your board specs (if that's the right board), you can set your memory speed separately. So you can run your RAM at 66mhz, & still set your CPU's FSB to 75, 83, 95, or 100mhz

in response 5 no my mobo looks the same but is a 5mvp3 rev. 2.0 not mvp3 rev. ce but thanks any way. allso i am running with 2 128 cards or sdram pc133 please if anyone can find a bios update please let me know!

what makes you think it's an asus board?
it wasn't mentioned, so why offer the link?
if you know anything about amd cpu's, you'd know how old the K6-2 is and that it would be impossible to use pc3200 with a k6-2, so why mention it?
you talk about 200 mhz as in 200 mhz (400 DDR), impossible with the k6-2

before giving advice,know what you're talking about, otherwise you look kinda on the silly side to those who know the facts..

sorry that was my monthly ration of wtf is up with that

I think you better look at the link I posted again...I believe that is your board...you're confusing the chipset model number with the motherboard model numer. The chipset number is VIA MVP3 rev. CE, but the motherboard is a Lucky Star model 5MVP3...look at the upper right corner of the screen for the name of the article...it's called:

Lucky Star 5MVP3 1 Mbyte

Follow my advice in response number 6 & you'll be running at the proper speed. If you don't wanna believe me, keep on posting...lol

ok thanks but i allready loked and it shows a older version or the bios so when i flashed now i cant use the settings that they said

Dude, no offense, but you seem to be a "newbie" at this stuff. You don't need to use those BIOS settings...they're agressive settings & it's very possible your RAM can't handle them. You need to setup your jumpers to correctly configure the board for your CPU. Did you read this note at the bottom of that page?

"All the configuration settings of the CPU parameters are shown in the user’s manual, while some are also present on the PCB of the motherboard; the configuration of the motherboard is a bit complex and it would have been better to use some switches instead of the jumpers"

The key part of that statement is: the configuration is COMPLEX! You have to have your motherboard manual handy & carefully setup the jumpers for your CPU & memory....

sorry but i dont have a manual

WTF? You could have saved a LOT of trouble by saying that 10 responses ago. Go to Google & search for it...
