Lenovo beep codes 1-3-3-1

I just bought 2 x 4GB RAM (Corsair Value Select 4GB DDR3 1066MHz CL7 SODIMM (CM3X4GSD1066)) for my Lenovo Thinkpad T400.

I mounted the RAM and also I gain beeps (1-3-3-1).

You watching: Lenovo beep codes 1-3-3-1

Does anyone have actually any kind of suggestions on just how to examine if the RAM are not problematic?





Current RAM module:




It"s bad RAM or a bad RAM slot. Put just one stick in and also view if it makes a noise. If it does, relocate it to an additional spot. Figure out which is the problem: a stick or the slots. You sassist you"re replacing so make sure the RAM is compatible through the board and also make certain the old RAM works and you didn"t damage the board upon installation of brand-new RAM.


T400 Supports as much as 4GB maximum memory. So Max 2GB per slot.

Looked roughly a little and other spec sheets say 8Gb. Make certain you have actually the latest bios update for your lapheight and also attempt aget.

The 1-3-3-1 is a RAM or mainboard error so you are on the ideal track. Have you tried one SODIMM at a time? One at a time in differt sockets? Try in one more system? What is teh specific model number of the T400?


I purchased an used Lenovo T400 Thinkpad with 2 GB RAM. It booted OK.I reput the 2GB with 2x4 GB RAM and also obtained the 1-3-3-1 beep.I found that if I turned the power on, got the beep, waited 10 minutes, turned the power off then on the computer would certainly boot.. It shows up that the T400 provides the RAM in its booting sequence. I then tried booting with each 4 GB independently and also the boot operated. I then tried booting via 4 GB in the prime slot and also 2 GB in the additional slot and also it functioned OK. The T400 simply can"t take care of 8 GB despite the spec statement.
