RAM Memory Slots

[rollonesown]

Apologies in advance for any technical inaccuracies. I'm not the most computer literate but I'm trying :doh:

I've recently had a new computer given to me, the stats on the Targa website says for memory:

"1024 MByte DDR II-RAM 667, exp. up to max. 4 GByte DDR II-RAM"


From my old computer I've got a stick of DDR PC-2700 RAM that I wanted to put into my new one. It doesn't want to slot into the holder even though it looks identical to the other memory, and I was wondering whether this would be something to do with the difference between DDR and DDR2 memory or whether I need to give it a bit more force.

Thanks for reading.

DDR and DDR2 are not compatible. DDR is 184-pin, 2.5-2.6V, whereas DDR2 is 240-pin, 1.8V. The slots and modules are designed to be incompatible with each other to prevent them being used with each other. It *can* fit, but not without damage to the module and/or motherboard.

Thanks very much. That clears things up. Better get on the hunt for some new RAM :]

Cheers again.

My new BL2KIT12864AA804 - 2GB kit (1GBx2), Ballistix 240-pin DIMM , DDR2 PC2-6400 from Crucial.com say 2.2v - my mobo was running it at 1.7 so I set it manually to 2.2 and seem to have noticed a bit more system stability (although this might just be my imagination) was I right to do so do you recon?

If you want something cheap, hunt around for SuperTalent DDR2.

If RAM doesn't have the proper voltage its chips require, yes, you can run into some instability.
