Thinkpads Forum

I've got a T60 enroute to me with 1GB of RAM, which I presume will be two 512MB sticks.

I have a 1GB stick from an R52.

The modules appear identical except the T60 is PC2-5300, CL=5, DDR2-667 and the R52 1GB is PC2-4200, CL=4 DDR2-5300.

Would it be possible to replace one 512MB module with the 1GB module from the R52?

Thanks,

Usually, IBM/Lenovo does the right thing and ships with a single 1GB module. That's been the case with every thinkpad I've received.

I'm not sure about mixing memory speeds in a T60. The system will probably throttle to the speed of the slowest memory, but I'm not sure.

Ron:

Well, I've had the opposite experience. Both ThinkPads I bought came with two smaller RAM modules rather than one large one.

Maybe I'll get lucky this time.

My T60 came with one memery module, and yes, if you insert a slower RAM-module they both run at the slower speed.

Kimx:

Does your T60 run well with 1GB? I've been reading various posts and they suggest that for normal use (e-mail, some surfing, word processing, no games or video editing, etc.) that more than 1GB may be superfluous.

That's correct. And if you put in a 1GB PC2-4200 module, you would slow down the machine even though the memory size goes up.

Yes I run my machine with 1GB, and it's very rare that I run out of memory.

I should note that I'm currently using vista as my primary OS, and I can't fell any slowdown compared to running XP.
