T400 DDR3 Ram upgrade

I am waiting for my T400 now; I placed the order a couple of days ago. the T400 I ordered is coming with one module 2gb ram. I intend to add another 2gb to work with vista x64.
I want to get a memory with the same specs as the original one. Would you please tell me what are the specs of the T400 DDR3 2gb ram?
Is there a place where I can get it in a good price? any recommendations?

 

You should just get the RAM from Lenovo's CPP. It should be the same thing as what whey put in the systems, if I'm not mistaking.

 

If you want to be completely sure, you can wait until you receive your system, then use a program like CPU-Z to identify the RAM.

edit: CPU-Z doesn't recognize DDR3 yet. Thanks for the update W500?.

 

Yeah, you should probably identify you RAM with CPU-Z and buy a similar one. I would recommend you a G.Skill model that fits with your other SO-DIMM.

 

I will get the original part since it is not expensive through lenovo.

thanks for the replies.

 

No you can't since cpu-z does not yet recognize ddr3.

 

my T400 came with ddr3-1066 CL7 RAM.
most of DDR3 SO DIMM on the market are from this category
just look for DDR3 SO DIMM 204 pin
(I bought this one Kingston ValueRAM SO-DIMM 2GB PC3-8500S CL7 (DDR3-1066) (KVR1066D3S7/2G))

EDIT:
end yes CPU Z and all other software that i tried doesn't recognise it as ddr3, they all show me that i have ddr2.

 

there are two versions of ddr3 at lenovo, either of them is fine. they are the same except made in two separate batches. i got one of each model .

I think this is the original T400 2gb memory module, can anyone confirm?

 

no there is the 2046 for some models like lenovo top seller models (what ever that means)
