Full Memory not recognized HP NX6325

[hebbal1273]

I decided to upgrade the ram from 1GB to 4GB on my HP laptop NX6325 with AMD Turion 64 X2 CPU 320GB hardisk. However the OS recognises only 2.87GB. It should show atleast 3+ GB. The OS is Windows XP 32 bit. I thought it was a OS limitation. However if I dual boot in Ubuntu 12.04 64 bit it also shows me the same number. It seems that the new hardware is not recognised.

However the bios shows full 4GB. Is there any setting I need to do?

BTW, the memory modules are 2X2GB DDR2 667Mhz SODIMM Transcend make. The specs are the same as mentioned in the manual

After I replace the memory modules, the bios detects the new memory but it says 3GB instead of 4GB & asks to hit F1 to save. However if I go inside the bios utility it shows 4096MB memory. I can even test it in the bios. Is it a bug in the bios. The version of bios is F07.

If you read the manual carefully, then you should also have seen that the maximum memory expansion is 2GB. If you are seeing almost 3 GB you should consider yourself lucky. The limitation is because of the chipset or BIOS restrictions.

Ok the manual that came with my laptop tells me that I can upgrade upto 4GB. If there is a chipset or BIOS limitation why would they advertise it?

There is a communication regarding 4GB ram. Check this out. So ideally my laptop should support 4GB.

I have this model

http://h18000.www1.hp.com/products/quickspecs/12447_div/12447_div.HTML

 The orginal factory specs read like this

AMD Turion 64 X2 Dual-Core Mobile Processor TL-50 (1.6-GHz, 2 x 256-KB L2 cache)

15.0-inch XGA (1024 x 768 resolution)

1024-MB 667-MHz DDR2 SDRAM

Now I want to upgrade from 1GB to 4GB

OK I have googled and googled. Everybody is telling that its a bug in the BIOS. Is there a fix for that? I have 68TT2 ver. F.07 which I believe is the latest. Help!!!!!

There does not appear to be a fix for it on the HP web support servers.

Thats a shame. HP claims to support 4GB & HP's own BIOS does not allow the OS to access the memory. When HP brought this product out, didn't they test it to check if a 64bit OS can access the full memory? Mind you it is not a computer assembled from different vendors to cause a problem. It is a branded laptop & we expect it to work as they advertise.

Hope HP comes out with a BIOS updates.
