can windows xp (32 bit) create a blue screen of death...

by sharpie2009 / January 29, 2009 2:18 PM PST

if the amount of RAM installed in the motherboard is greater then the approximated 3.2GB? I have been having this problem ever since i bought my two new dual channel 2GB set (2x1GB), and before i had a 1GB set (2x512MB). I plugged the new memory in, worked perfectly, was even recognized by my Smart RAM program but once i ran 3DMark05 (yea i know old version but it was a trial), i got a blue screen of death. I'm thinking of just sticking with the 2GB set, but if 3GB is possible, why not?
My system specs:
ASUS P5B Deluxe edition, wifi-ap
Intel Core 2 Duo E6400 2.13ghz
XFX 8800gt XXX-edition

ask if any othr info is needed.

The answer is in the question.

"if the amount of RAM installed in the motherboard is greater then the approximated 3.2GB?"

I think you are fishing for an affirmative that "this causes that." No, XP doesn't bluescreen just because you installed over 3.2GB RAM. It is however prone to BSOD for a few million reasons.

In your case you may be encountering a common problem of memory compatibility. Too many think that if it plugs in, it should be fine. Some know that's not entirely true and stick to brand ram.

As more get burnt over failed memory upgrades they learn about the BIOS version (it matters) and that if we don't use memory that's "on the list" by the maker then we know to dive into the bios to compare the ram voltage and timing settings and HOPE that we can tweak those to make it work.

This is not an offer to write a tutorial. Just sharing that it's not that.

hey Bob, thanks for the help, but both of my dual-channel ram sets are at DDR2 667MHz PC-5300, and I'm not actually surpassing the 3.2GB that windows xp kinda limits. I'm only at 3007MB of RAM (according to Smart RAM) and up until today, I have only received the BSOD while testing my graphics via 3DMark05 or while playing some computer games. Also, if anybody here does play WoW, i have a few questions that I would rather ask here then the WoW forums because of the maturity level there.
Thanks for spending the time to read my problem and writing a possible solution

You told me 5% of the memory specs.

"DDR2 667MHz PC-5300" scratches the surface of specifications. That is never enough to tell anyone that such ram will work in so and so's board.

Maybe no one told you this till today but Crucial.com looks into such things, the motherboard, machine makers and then you tell us about WHEN IT FAILS.

-> I vote that when stuff is almost compatible it would be nice it would just fail and stay failed.

sorry, i realized what was missing. My RAM manufacturer is Kingston, the brand is ValueRAM. I originally bought my 1GB (2 x 512MB) set in 2006, and just recently, in November, upgraded with the 2GB set. It is non-ECC and the test said that my motherboard does not support it. Any other information, as I said before, is on the scanner results.

Your machine.

Your work to be done.

1. Is the BIOS current?
2. Is the BIOS set to support your new RAM?
a. Vram.
b. Timing.

You never told. I know that most of us never imagined that we couldn't just pop in more ram.

Possible issue
by Willy / January 29, 2009 9:58 PM PST

This maybe an example of the "straw that broke the camel back". While the 32-bit can acknowledge the presence of more than 3gb of ram it WON'T be able to use it. Further, depending on your mtrbd., that too must be capable of even having 2gb sticks installed per slot, be sure what the specs are. You need the latest MS updates, etc., to continue on and whatever the bios may supply if this touches on that issue.

You pretty much answered you're own question. Leave well enough alone as your old setup worked. Excluding any other cause, go back.

Like the doc said, "if it hurts, stop doing it".

>> can windows xp (32 bit) create a blue screen of death if the amount of RAM installed in the motherboard is greater then the approximated 3.2GB?

Assuming you have compatible RAMs, if the PC sits idling or running well behaved, API-respectful programs, NO.

If you run memory probes and intrusive programs, absolutely YES.

So whacha gonna do?

Another tack is to drop down to 2GB max in the system. It's usually, but not definitely, a safer limit for commercially available programs. Try it with the 1GB set thrown out.

suggest you reconfigure/test your ram
by ramarc / January 29, 2009 11:19 PM PST

install cpu-z: http://www.cpuid.com/cpuz.php
refer to the SPD tab to get your programmed RAM timings and compare that to the actual timings on the Memory tab. sometimes a mobo won't automatically set the proper timings. if so, manually set them in the BIOS.

download microsoft's diagnostic tool to test your ram:

if the test fails, drop back to a more conservative memory speed/timing such as ddr2-800 or ddr2-667 with timings of CL 5-5-5-15.
