X60 compatibility with OCZ PC2 6400 2x2GB kit.

[phoenixz]

Hi,

I just bought 4gb of memory (ocz2m8004gk, PC2 6400, 2x2GB non-ECC kit retail) for my X60 (1709-47U, Core Duo). The computer won't start at all. It gives 1 short beep, pause, then 4 short beeps, pause, then 2 more short beeps. It doesn't match the beep symptoms listed on the Lenovo website so I called tech support, who told me the code indicates a memory problem but nothing further can be said without me giving them the laptop.

My questions:

1) How do I find out if the new memory is good or bad?
2) Has anyone used this particular OCZ kit on an X6x with success?
3) I assume I can buy PC2-6400 and it will simply run at the lower 5300 speed. Is it not true?
4) Any other suggestions? Recommendations of good 4GB kit that's known to work?

Thanks!

UPDATE: It works!

I can not explain what happened. Here's what I tried after posting this message:

- Unplug everything.
- Put 2GB memory 1 only in left socket. Beeps 1-4-2.
- Put 2GB memory 1 only in right socket. Beeps 1-3-3-1.
- Put 2GB memory 2 only in left socket. Beeps 1-4-3-3.
- Put 2GB memory 2 only in right socket. WORKS!
- Put 2GB memory 1 only in right socket again. WORKS!
- Put both in. BOTH WORK!!!

This makes zero sense to me. I've installed memory numerous times and I'm very sure I installed the modules securely every time. Anyway, now I'm happy

OCZ sells good quality memory under their brand name, which is not to say that there aren't occasional bad modules, which one can get from any manufacturer. I have received good service from this company with both RAM and flash memory purchases. What is more is that they have never failed me in the payment of rebates, something I cannot say for some other companies, most notably (and recently), G. Skill.

I have 2 OCZ 2GB sticks in my X61s working perfectly. No problems from the get-go.

Good to see you got yours working, but keep an eye on them and I'd recommend doing some memory tests.
