T400 - Win 7 Professional - 6 and 8GB ram crashes...

Hi,

 

I need help with the following issue, please…

 

I have Lenovo T400 model # 6474-11U and I have installed Win 7 professional 64 bit on it.

 

Intel core 2 duo P8400 2.26 Ghz processor

 

When I upgrade ram to 6GB, windows boot but occasionally I get blue screen. Windows shows full 6GB installed.

 

For 8Gb, windows doesn’t even boot. It just crashes during the boot process.

 

For both, bios shows the right amount of memory installed under system summary.

 

Thanks

which ram model did you get? brand?

Also, can you run a memtest+?

what if you run one stick of the 4 gigs?

Also have you updated the bios?
