Bad Memory ?

[Mike Klaiber]

I have just upgraded from 256 MB SDSRAM to 512 MB DDR

On start up the machine gave an uncharacteristic 3 long bleeps, and kept
repeating. It would only go into boot up after pressing the PC reset button.
I was then presented with the system boot menu. Normal Windows would not
load and I could only get into "safe mode". I have re-fitted the memory in
the other motherboard slot, with the same result. I was eventually able to
get into Windows but showing 4 bit colour only. I later discovered that my
graphics driver had uninstalled. Re-installing the graphics driver seemed to
make things OK until I connected my ADSL modem which caused the system to
suddenly shut down and go into re-start. This reverted to the system boot
menu.

I've un-installed and re-installed the modem software, but that has made no
difference.

After (some) program loading the mouse pointer goes unresponsive and jerky.

When I power down and restart later, I'm back to 3 bleeps and will only boot
up with the re-set button.

The same thing happens coming out of hibernation.

Re-fitting my old 256 MB SDRAM, the system works normally.

I've followed the advice from Crucial and the motherboard literature about
compatible memory. I have fitted the correct component, and taken great care
in fitting. However, this is causing serious problems and I can only
conclude that the memory stick supplied is faulty. Crucial seem reluctant to
replace.

On their advice I have run the Microsoft memory diagnostic utility with the
512MB DDR RAM fitted on standard and extended test. No errors were found.

I've been into the Bios. SDRAM frequency is set at auto. I've re-set to 200
& 266 but with same problems on power up.

I have an A S Rock K7VT2 mainboard with an AMD Athlon XP 2000+ processor.

Can anyone offer any guidance as to what the problem might be, please ? Is
this bad memory, or what ?

Any help would be appreciated. I do not have much technical knowledge.

This motherboard supports PC1600/PC2100 DDR DIMMs only.

 

[Duh]

That is not true, the motherboard has both SDRAM and DDR memory slots and
supports either.

Google around for memtest86.exe. That seems to be the RAM test that is
most trusted.

You installed new RAM and have serious problems. Why would you look anywhere
else, except at the RAM?

Did I say it doesn't support SDRAM?

 

[Mike Klaiber]

Thanks for your replies.

The motherboard does support both SDRAM & DDR. The stick I have is PC2100.

Does this sound like a bad component ?

I also had the same problem. I had a K7VT2 mobo with
athlon xp 1900+. RAM was a PC2100 Kingston 512mb DDR. All
I did was reinstalling the memory, switching DIMM slots,
and if I didn't want to, I just waited about one, two, or
three minutes and windows started up fine. Ever since I
did that, my PC was running well and never had that
problem again. Probably it was because I reformated my
hard drive and reinstalled XP Pro. That was a long time
ago. I just upgraded my mobo and cpu to intel 2.80 HT.
Same memory RAM and no problem at all.

 

[Jim Macklin]

You can't run both the PC133 SDRAM and the PC2100 (PC266)
DDR RAM at the same time, run only the PC2100 and see if
that fixes your problem.

Thanks. I had already swapped the memory sticks. I understand the point
about SDRAM being fitted the same time as DDR.

Sorry, I'm not quite following what you have said:

"All I did was reinstalling the memory, switching DIMM slots, and if I
didn't want to, I just waited about one, two, or three minutes and windows
started up fine."

Are you saying that after changing from SDRAM to the new DDR, you just
waited a few minutes before trying to re-boot ?
