Hi folks,
Had a query regarding a RAM upgrade that I just did that has caused some problems.
My computer specs are as below, comp is approx 4 months old. First build for me, and there have been soem teething problems, but nothing extreme.

The problem arose just recently, when I purchased another 2Gb of Patriot RAM to upgrade the system to 4Gb.
The RAM is identical.
When I initially slotted the new RAM alongside the old, the comp failed to boot. Removed it and it booted fine.
Then, I increased the motherboard RAM voltage by 0.4v to 2.2v as recommended by Patriot for this RAM. The 2 Gb worked fine after this.
I then added the new 2Gb alongside.
The computer woudl then boot, but recognizes only 3.5Gb in System.
In addition, the comp runs unstable, with frequent error messages.
The RAM is HOT, almost too hot to keep a finger on it right after shutting down.

I have not played with the timings or OC'ed the RAM ( as I am planning to do as soon as this issue is sorted out)
The PCU is stock, not OC'd.

I tried to run MS RAM diagnostic utility, and got failure across the board, with the exception of MATS and INVC, which passed. I have no idea what this means, but I tried to get as much info before posting here.


I'm not a complete n00b, nor do I have crazy skills. Just looking for a helping hand with some experitse for sorting this issue.

Many thanks in advance for your help,

-T

The 32 bit versions of XP and Vista will only recognize 3.25 to 3.5 gB of the 4 gB that you've got installed - this is normal (I do this on my system). The other RAM issues aren't normal, although raising the voltage will generally raise the temperature of the RAM.

Will the old RAM work in the other slots without the new RAM installed? Otherwise, I'd suspect an issue with the motherboard - there may be mention in the motherboard manual, or you may have to contact Gigabyte for additional information.

all 4 sticks have the same exact number?

you might try in flex mode

make sure 1 and 3
2 and 4
are from the same batch

you might have to increase air flow around them

test each stick with memtest from a boot cd

No. Try not. Do... or do not. There is no try.

Thanks for the suggestions, folks.
All sticks are of identical make, 1&3, 2&4 are from the same package, will check for batch.
I have a huge Zallman cooler pointed at them, they were very hot to the touch after testing, but otherwise are relatively cool.
I have decreased teh voltage by 0.1, which has semed to help with the stability.

Mad busy tdy, but will test and post when I get the chance.

Is it possible to run a 64 bit OS so that I can get the joy of all 4 Gb?

one quick test is pull one of the new sticks, that should kick you out of dual channel mode

then test with the other new stick

unfortunately flex mode is an auto setting if it detects different sizes but probably not smart enough to detect different chipsets
on the ram sticks

you would have to examine old vs new

No. Try not. Do... or do not. There is no try.

You can run 64 bit, but would have to buy a new copy of Windows to do it. Before purchasing, I'd check to ensure that there are drivers available for all of your hardware devices - if not available, you'll have difficulties with it.
