Hello,

I recently bought new RAM for my thinkpad x200 and the laptop won't boot after installing it. I press the power button and it simply gives me a series of short beeps. My theory is that the x200 can't support 1600 mhz memory. Is this true? Here are the RAM specs that I bought:

Team TSD38192M1600C11DC-E

204-Pin DDR3 SO-DIMM

8GB (2 x 4GB) DDR3 1600

Cas Latency 11

Voltage 1.5V  

I've tried a single stick, dual sticks, combo with my stock memory, and it won't work. Can anyone confirm that this is incompatible memory or is the memory faulty?

Hi,

Welcome to Lenovo Community!

I’m sorry to hear that you are facing the issue with memory on ThinkPad x200.

I regret to inform you that ThinkPad X200 will not support 1600 Mhz bus speed, here is the specification

Non-Parity (NP) Double Data Rate Three (DDR3) Technology

Two SO-DIMM Slots

The use of 1066 MHz SO DIMM memory is recommended for this system.

512MB, 1 GB, or 2GB memory

Supports up to 4GB maximum memory

Hope this helps!
