2RX8 in DDR2 for T61
2RX8 in DDR2 for T61
Hey everybody
I'm upgrading my T61 with more ram and I found two almost identical DDR2 SDRAM from Crucial. The only difference there is 2RX8 in the description. So basically that's what the one is called:
Crucial 8 GB 2X 4 GB PC2-6400 DDR2 PC6400 800 Mhz SoDimm 200pin Laptop Memory
and that is what the other one:
8GB Crucial Kit 2X 4GB 2RX8 PC2-6400 DDR2-800MHz 200pin SODIMM Laptop Memory @DD
and I'm just curious which is the one that's appropriate (right one) for my T61 (with the pretty standard set-up plus Middleton's Bios
Thank you in advance and a good day to you all.

Re: 2RX8 in DDR2 for T61
Pretty sure for 4GB sticks, both are 2Rx8 and both should work fine on T61 after Middleton.
I have some available if you are interested.

Re: 2RX8 in DDR2 for T61
I got my old T61 back after loaning it to my mom for 10+ years. The battery still works fine!
Man, I had forgotten how nice the keyboard was. The T420 keyboard -usually taken as a reference- isn't that good in comparison.
How much are you asking? I don't really need it... but I have the feeling that it'll end up in the landfill if I don't give it a second life.
It's a custom T8300 + IGP + SXGA+ (14.1"). It currently has 1GB of RAM and a spinning drive.

For the sake of ecology I donated all my classic Thinkpads.

Re: 2RX8 in DDR2 for T61
So it would be C$55 + postage for the pair. Again it is a pair of Micron sticks and SPD are unlocked (I've used them on half a dozen different machines to run 1066Mhz FSB by now). I'd only have one pair for sale now - I need the rest of them in my own systemsmikemex wrote: ↑Thu Mar 31, 2022 10:27 amI got my old T61 back after loaning it to my mom for 10+ years.
