I've got a 2623-DDU and I'm looking to add more than 2G of RAM to it. I know I don't have a 64-bit processor, so no real point in adding 2x2G chips. Can I mix and match? Can I add a 2G and 1G chip for a total of 3G? Our IT guys told me no, not possible.... but I'm not sure I buy that. Anyone?

Like most IT guys, your IT guy is full of it.

3GB is no problem in a T60, but here are things to consider:

1) EXPENSIVE - 2GB chips currently go for $500+ (vs about $100/GB on 1GB chips)
2) No dual channel memory access - this really isn't a big dea. At BEST you get 5% better performance on SOME applications with this (not overall system performance).

Do you REALLY need 3GB though? I multitask like a monster w/ some pretty huge apps (Visual Studio, Acrobat Pro 200+ page docs, Photoshop, etc.) and rarely hit the 1.5GB mark in utilization.

I'm doing a lot of VMWare images, so RAM access - even slow RAM access is faster than hitting disk. I'm usually running an IDE on the host and hitting an Application Server running in the VM.

Hi brentpresley,

Could you explain why it will lose dual channel memory access with 3GB?

Thanks

Just be prepared to pay out the nose for the RAM then. It is possible, but there is nowhere to find this stuff cheap. Newegg doesn't even carry it.
