T61p: questions on 8GB RAM upgrade

[crg7]

Hello:

1. Kingston's KTL-TP667/4G seems to work in upgrading to 8GB
Does CT2KIT51264AC667 (4GB x 2) also work? The latter is substantially cheaper.
2. Kingston RAM has no latency info available while the crucial one has a latency of 5. Does it matter?
3. Any motherboards, chipsets, variants of t61p that do not upgrade to 8GB?
4. Other suggestions?

Thanks

1. Yep, it works also.
2. CL5 is good, CL6 is ok too, but a bit less "speedy".
3. I think all of them are compatible -> PM965/GM965 chipset is the same!
