Re: memtest 86 pass on one computer fails on another.

Make sure that you only run Memtest86 on one stick at a time. If it finds errors on two sticks they may be false positives.

 

Re: memtest 86 pass on one computer fails on another.

I'm getting errors in memtest on one machine, but not when I put the same memory in another, what does that mean?

It can mean one of two things:
- The machine that is giving the errors is defective. Errors don't just originate from the memory module itself, but can also be caused by defects in the CPU, chipset, motherboard, PSU and even by timing issues introduced by any other component in the machine.
- The machine giving the errors is imposing stricter timing than the other which the memory module simply can't cope with. If the module should work with the machine according to its specifications then it most likely is defective.

You may want to read all the info and see what relevant

What motherboard do you have?
What speed ram?

The 250W psu may be the problem but answer my questions and we will see

 

Re: memtest 86 pass on one computer fails on another.

the mother board is a ecs 741gx-m2 link
the ram is ddr 400 184 pinn
the power supply is a weak but it has worked for years with the same set up maybe it degraded.

 

Re: memtest 86 pass on one computer fails on another.

it still gets errors when i run it with just one stick of ram AND
RAM IS PC3200 CL2.5 -4-4-8 2.5V-2.6

 

Re: memtest 86 pass on one computer fails on another.

You should probably replace that PSU soon.

 

Re: memtest 86 pass on one computer fails on another.

Go into bios and set the ram clock to 166mhz try and load windows if it don't work set the ram clock to 133mhz and try again.

If you know what cpu you have other than 1.9 that would really help, I have to go right now but will be in later this evening and I will explain why you should try that.

But still Matt is right on, the psu should be changed, we may just be chasing our tail with a 250W in there thats that old

 

Re: memtest 86 pass on one computer fails on another.

Processor Amd Athlon Xp 2600+1.91ghz

 

Re: memtest 86 pass on one computer fails on another.

i THINK I FOUND THE PROBLEM LOOKING THROUGH THE BIOS I noticed that the cpu is at 118c. does this mean processor is bad or could something else make the processor get this hot. the processor was clocked at 166 when i brought it to 133 temps went to 82 and then when i brought it down to 100 temps went to 71. could a old bad power supply make the processor run very hot.

 

Re: memtest 86 pass on one computer fails on another.

Is the fan on the Processor heatsink running? . . is the case full of dust bunies? . . Have you removed and replaced the heatsink recently? . .

 

Re: memtest 86 pass on one computer fails on another.

the fan is running and there is not really any dust in it. and i have not done anything to the heat sink.

 

Re: memtest 86 pass on one computer fails on another.

If the processor was really that hot it would have literally fried. I think the BIOS reading is wrong. My bet is on the PSU as the problem. Do you have another PSU you can try?

 

Re: memtest 86 pass on one computer fails on another.

. . . dang . .

 

Re: memtest 86 pass on one computer fails on another.

I agree replace the psu before we go any further, its old and too small for the system, a system like yours needs 400W of good clean power.

That would be perfect

That would be Ok

 

Re: memtest 86 pass on one computer fails on another.

I had an extra 500watt psu for a computer i am building my roommate. I put it in but it really didn't make much of a difference. the temps maybe when down a few degrees. so them i decided to put new thermal past on the processor.
this was not the best idea because now at 100hz clock the chip is at around 97c ,maybe the thermal past isnt set yet but this guy is running hot!!! I have been using HMonitor and speedfan and they both say it is very hot.

is CPU broken

 

Re: memtest 86 pass on one computer fails on another.

No the cpu ain't broken, you most likely did not put the thermal paste on correct.

Instructions here http://www.arcticsilver.com/arctic_silver_instructions.htm

Also and this is important,,,,,,,, It is possible to install a socket A cpu heatsink 180 degrees in the wrong direction,,,,,,,, look at the bottom of the heatsink the step in the heatsink must face the part of the cpu socket that says 462.

Remove the heatsink, clean and reapply the thermal paste following the instructions, make sure the heatsink is mounted correctly and down tight.

Post back

 

Re: memtest 86 pass on one computer fails on another.

nice i got it i think i had the head sink on 180degrees wrong thanks again for all your help guys. you have done it again

 

Great news! and your welcome

 

Good call Doby! !
