Installing Ram from another PC

[Julz83]

Hi all so iv'e tried to install two sticks of memory into my pc that has two 4gig existing sticks already. The two i'm trying to install are only 2gig each so i'll have a total of 12gigs . Problem is windows won't start unless i take them out. Their make is 2GB 1RX8. I took them from an old work computer that was destined tobe thrown out. Is it that these two sticks are not compatible with the motherboard?

It seems like that's the issue. You cannot just mix and match RAM like that, especially if you're not certain it's compatible with the other ram, the CPU, and the motherboard.

What are the model ram sticks.

There is cas, timings, and voltages and these things all have to be the same.

Then there is issues like the high density ddr2 ram, or the HP/Dells with bios that only supported whitelisted hardware.

Even if they are identical in specs, some ram sets are incompatible, thats why ram comes in SETS, they are designed to work well together, if this causes your PC to not boot/crash then they are obviously not compatible

I was thinknig the model and age of the ram plus the fact it came from a specifically built office computer culd be the issue. I've removed them and every thing is fine and i won't bother attempting to put em back in. Thnks for the fast response guys

"Is it that these two sticks are not compatible with the motherboard?"

You ask a question like that but don't include the motherboard model? - - - brilliant.
