Won't recognize RA total

Compaq hp / Evo d51s sff

Specs: Windows XP Pro, 1 gb/256 m
I upgraded my RAM to 1,25 GB but system only 'sees' 256 mb. I ran crucial.com and it 'sees' the total. The bios is showing the 256 only. I swapped the two sticks and got the same results. I pulled the 256 and left the 1 gb and nothing - it just won't 'see' the 1 gb. How do I get it to 'see' the whole RAM??

Crucial may have been reading the SPD chip on the ram stick and not seeing it through the OS.

In any event, the stick is either bad or incompatible with your system. It looks like it originally came with PC2100 ram. You probably put in something faster, which is usually OK but there are limits. There could be a density problem too wherein the motherboard chipset isn't able to work with ram chips having a large memory capacity.

Check at crucial for compatible ram specs. They're usually right. Buy it from them or check ebay or computer shops.

Now that's what I call a sticky situation

Ran crucial.com again and it still recognizes 1.25 GB and tells me to use the type of sticks I have in it. Can only assume that the stick I have is bad and will get another gb of RAM.
Thanks,
Ray

Unless you got it from a questionable source I think it's more likely to be incompatible than bad. You need to look for a low density stick. Or, two 512 meg sticks may work better than the one 1 gig.

I'm currently looking at Kingston 1GB 2x512MB PC2700 DDR333 PC2700U Non-ECC DDR or this one 1 GB (2X512) PC2700 DDR 333 MHz DESKTOP MEMORY. Even though crucial.com said either a 2700 or 3300 would work, I thought I'd slow it down a bit.
