8440P EliteBook
Microsoft Windows 7 (64-bit)

I recently decided to upgrade the memory on my 8440P EliteBook. After reading through required RAM specs, I bought one of these: http://www.ebuyer.com/737970-kingston-4gb-1333mhz-204-pin-cl9-ddr3-sodimm-non-ecc-unbuffered-1-5v-me...

 

Once the new RAM is installed in the expansion slot, Windows fails to boot and just hangs at the "Starting Windows" screen. I then attempted a memory test using the BIOS system diagnostic tool, but the laptop either hangs at around 35% (I left it there for almost two hours), restarts, or shuts down altogether. I thought I'd give the system repair tool a try, but that also just caused the laptop to restart. Interestingly enough, when I check the "System Information" tab in system diagnostics, both RAM sticks are detected with all information present and correct.

 

I contacted eBuyer, they sent a replacement out, but I'm having the same problem again. So, I thought I'd try installing the new RAM in the internal slot instead (under the keyboard), but now I get a BSOD during the "Starting Windows" screen, giving me the error code, "IRQL_NOT_LESS_OR_EQUAL".

 

I've been reading up on a few tech forums. One of them suggested running something called "Memtest" on startup via CD, which I did try, but the laptop just restarts itself during the first pass of the memory test (and obviously just loops over and over until I remove the CD).

 

I'm beginning to lose all hope! Any help/tips/suggestions would greatly appreciated.

Hi:

 

See this related post.  You have to use very specific memory in that model or it won't work.

Hi BH,

 

Many thanks for the reply. The link tells me "Part 599092-001 is no longer supplied. Please order the replacement, 641369-001". Will this replacement part be suitable for my laptop?
