AMD XP2100+ woes

[SuperKen!]

Hi, I am having problems running my XP2100+ in my Abit KT7A-Raid board (probably revision 1.0)

For the past 2-3 years i have been running a T-bird 850 at 133*7 flawlessly.
I have 2 stick of RAM
256MB Crucial PC-133
128MB Micron PC-133

First off let me say that i am aware of the "officially" supported CPU's with this board.

Now when i got the XP2100+ today, the board detected the CPU fine as XP2100+ (pally core) and would POST fine.
But upon loading windows it would stall.
The highest I could get was 126MHz FSB to work.

Then I decided to take out the 128MB Micron PC-133 RAM and was able to load up Windows at 133MHz FSB, but it would stall upon login.
I am now running 130MHz FSB and is stable so far.

This makes me think that there is somethign wrong with my RAM, but i have been running it at 133MHz ever since i got the board.

Any help would be appreciated to help me solve my problem.

Thanks

I'll go ahead and ask....

Temps? Voltages?

 

[SuperKen!]

voltage is 1.75
temps range from 52-55C

I am wondering if the MB is having issue with supply enogh juice for your setup.

Ya. Sounds like power supply inadequacy problem to me.

check the vcore...
also run memtest86 if you suspect any ram problems.

 

[SuperKen!]

Thanks for the replies guys, I have the Antec 300W P/S that came out on top of Anand's first power supply review. Hopefully, that one is still good enough. If it isnt, please tell me.

I will download memtest86 right now and check it out.

why don't you try disconnecting the hard drive and CDRom etc from the power supply and motherboard and see if you can boot. If you can, then it's a power issue.

 

[SuperKen!]

ok, I disconnected both CD/DVD ROM drives and windows still would not boot up at 133FSB.

Curiously, i put back in my 128MB Micron RAM into a different RAM slot and it booted up at 130FSB.
But, looking at cpuip and VIA hardware monitor, the vcore went down about .2v after i put in the other stick of RAM.
I did not change the vcore in BIOS.

I will now try to raise the vcore up a little.

BTW it is an Antec 300w PP-303X power supply

Thanks for all the help.

Something sounds strange to me, but maybe I missed it. A Athlon 850 runs a 100 fsb, and the most that people I have seen are able to do with that setup is 110. There may be a change your memory is really PC 100 ?? That is my first guess.

I had the 300w antec power supply when I upgraded to a 1900 xp, I had similar problems like yours.
I switched to a 450w PC power and cooling power supply and everything went alright.
My antec did boot into windows however.

 

[SuperKen!]

Mark, your right about the 850Athlon, but I unlocked mine so I ran it at 133*7 so 933 MHz.

BillyJack, mine boots into windows at 133FSB SOMETIMES, but right before login it would stall.
Now, at 131FSB it will log into windows, but stall maybe 3 minutes after that
130FSB is working good now, havent had any problems with it yet.

Maybe, ill try and swap out a PS with one of my friends.

I am useing an antec 300W power supply along with a XP 2100+ on a 8-RDA+ and I'm haveing no
problem's. Course I'm not overclocking.

 

[SuperKen!]

Ok, switching out a power supply yielded the same the result.

Another interesting thing is when i run it at 130FSB Prime 95 will error immediately.
When i took the FSB to 125 Prime 95 would work fine.

Im not overclocking or anything.....could this just be a bad CPU???


Thanks for the replies.
