A few years ago i had to buy a new cpu and motherboard, so i went out and bought an AMD 2100+ Athlon, and a Gigabyte GA-7VAX.

Any way i have never been able to run it at it's full speed, currently it is running as an AMD 1500+ at about 1.34mhz, if I try it any higher it overheats and i have to lower it again.

Here is the html report from cpuz.

Ive try'd to increase the Front Side Bus Frequency 107.0 MHz
that's when it starts to hang, again i'll double check tonight.

Name AMD Athlon XP
Code Name Palomino
Specification AMD Athlon(tm) XP 1500+
Family / Model / Stepping 6 6 2
Extended Family / Model 7 6
Package Socket A
Core Stepping A5

L2 Speed 1337.4 MHz (Full)
L2 Location On Chip
L2 Data Prefetch Logic yes
L2 Bus Width 64 bits

Motherboard manufacturer Gigabyte Technology Co., Ltd.
Motherboard model GA-7VAX,
BIOS vendor Award Software International, Inc.
BIOS revision F7
BIOS release date 10/31/2002
Chipset VIA KT400 (VT8377) rev. 00

Sensor chip ITE 0

DRAM Type DDR-SDRAM
DRAM Size 768 MBytes

Module 1 Hyundai Electronics DDR-SDRAM PC2100 - 256 MBytes
Module 2 Hyundai Electronics DDR-SDRAM PC2100 - 256 MBytes

Here are some settings from my bios.

VCore 1.772
DDR Vtt 1.232

Current System Temp 46
Fan Speed 3750rpm
No System fan(could be unplugged actually)
CPU Temp 52/125 ( to high i guess)

Some other settings to do with memory
DRAM Clock [auto] ( other options were 100-DDR200, 133 - DDR266 and 166 - DDR333

Cheers.

haha, 1337
thats always gl


anyways on topic... thats seems like a VERY high case temp, and even higher cpu temp. Im not sure about older athlons but isnt vcore supposed to be at 1.5v? might be that

EDIT: and isnt Vdimm supposed to be at like 2.7v? not 1.232?

sorry, i dont know about the older processors but that is strange

Please fill out your system specs in User CP -- it makes it easier for us to see what you're running.

Do you have an aftermarket HSF for your CPU or still using what came with it?

It was a few years ago, but ive got a feeling when i bought the cpu i have to buy a fan as well, and i still use the same one now, so i guess it would be an aftermarket.

I'll check tonight and maybe get some pics to show.

the 2100+ has 133 fsb, not 100/107
You can change the settings from the bios, or some jumpers on the board (I bet there are the blue ones 1 to 5 near the cpu soket) If you have a manual of the board you could read it, it usualy helps.

Yea, as the poster above said, you probably didn't set the correct fsb for the board. You can find all the info in the manual for the board. Your temps are kinda high so maybe you should wait to get better cooling for the cpu before switching to the higher fsb. I'm not too suprised that the vcore is at 1.77 because the chip is built on older technology 180nm so it requires more juice to run the transistors. Also, you should check to see if your system fan is directly connected to the motherboard via a 3-pin connector or connected via a molex connector. If it is via a molex connector then it will not show up in the BIOS. If it is via a 3-pin connector then something may be wrong with the fan, which should be taken care of to promote betting cooling for your system.

Thanks for your reply's.

I can change the fsb in the bios, and any higher than 107 and it starts to become unstable, do i have to change it on the board as well? or is the bios enough to change?

The system fan connects to a 2 pin connector so i guess that would be the molex u mention.

Ok i have now changed the system bus speed on the mother board to 133, and my fsb is now at 140, the temps are still hot but every thing is stable for now. And it is set as a AMD Athlon 2100+

I'm only getting 12.5x, is it possible to get the 13 im suppose to be getting for the 2100+ at 133.

Also is it possible to get any more out of the 2100+?

This CPU is a ho potato, I've had one myself. You would need a lot of cooling to overclock it. Better to change to a cheep board with a Cempron if you want more performance without paying much. By the way, 1.7V Vcore is correct for this CPU.

did you make sure that on the mobo their supposed to be a jumper the set the speed (short for slow and open for fast) you gotta make sure that its on open for full speed.

Go check out the vid card forums. The guides on how to are there.
