I'm looking to upgrade the CPU on a laptop, and am having a hard time verifying the DDR type of CPUs. The laptop has a T5250. So, for upgrading, I'm looking at the X7900 and T9500, which are the two best this socket can take. But, I need to check the DDR type of the current CPU, and of the potential upgrades. Intel doesn't specify the DDR type on the specs page, or even in the ~hundred-page datasheets.
The RAM in the laptop is DDR2. I couldn't find details on the mobo, but I'm pretty sure it's DDR2 as well. I searched around, but just ended up with more questions. I see T5250 in old systems with DDR and DDR2. I see the X7900 only in DDR2 builds, and the T9500 in both DDR2 and DDR3.
So, the questions is: will the T9500 work with DDR2?
