Help with upgrading RAM

will962 · 08-15-2008, 04:27 AM

Hi fellas, I recently bought a 512MB DDR RAM stick for my HP workstation xw5000. Before I had 2 256MB DDR sticks so I wanted to upgrade to near enough 1GB.

When I put the new 512MB stick in with the 256MB sticks my computer coms up with "Memory loading error" I tried using only the 512MB and 1 256MB stick and it said "Memory mismatch errror". I know the new RAM works because I have it in now on its own.

I've tried a BIOS upgrade (no difference) and putting the RAM in different slots.

Help would be much appreciated

What's the problem? You said "I know the new RAM works because I have it in now on its own.". If you are trying to mix the 256 and 512, you probably can't. You would need to check the book/online for your specific model to see what the mix/match possibilities are, but, I'm guessing you can't mix them or they have to be the same size and speed.

yeah I am mixing them, thats probably the problem. I'll buy another 512MB stick and see if that works.

Thanks for the reply

np. I'd check the specs on the board first just to make sure and see if there is a requirement that the clock speeds on the two need to be the same - just to make sure.
