I was wondering whether anyone knows what type of memory a Compaq A975EM and what is the maximum amount it can take.

Thanks

According to a quick Google:

Max: 3GB

DDR2 SODIMM 667MHz

Says it supports upto 3GB of DDR2

It had to be 3 not 4. Just to be awkward. Thanks guys though.

How many slots does it have? I could get 3 1GB's in there. would these be O.K: 1GB, DDR2 PC2-5300 (667), 240 Pin, Non-ECC Unbuffered, CAS 5-5-5-15.

Or could I get one 2GB and one 1GB? It looks as if it already has 3GB. Could I get faster modules in there or not?

Hmm the spec sheet just sas 1x2GB 1x1GB doesn't say how many slots - 2 I imagine though.

Does this help?

If I cannot upgrade the RAM I may go for hard drive or processor update. It say's pentium dual core but what socket is it? Also what make of SATA is it, could I put a SATA III hard drive in a SATA I slot?

Thanks

From what I can find it's just SATA I

From Wikipedia:

SATA 1.5 Gbit/s and SATA 3 Gbit/s
The designers of SATA aimed for backward and forward compatibility with future revisions of the SATA standard.[citation needed] To prevent interoperability problems that could occur when next generation SATA drives are installed on motherboards with legacy standard SATA 1.5 Gbit/s motherboard host controllers, many manufacturers have made it easy to switch those newer drives to the previous standard's mode. For example, Seagate/Maxtor has added a user-accessible jumper-switch, known as the Force 150, to enable the drive to be switched between 1.5 Gbit/s and 3 Gbit/s operation. Western Digital uses a jumper setting called OPT1 Enabled to force 1.5 Gbit/s data transfer speed (OPT1 is enabled by putting the jumper on pins 5 & 6). Samsung drives can be switched to 1.5 Gbit/s mode using software that may be downloaded from the manufacturer's website. Upgrading a Samsung drive in this manner requires the temporary use of a SATA-2 (SATA 3.0 Gbit/s) controller while programming the drive.
The Force 150 switch is also useful when attaching SATA 300 hard drives on SATA controllers on PCI cards, since many of these controllers (such as the Silicon Images chips) will run at SATA300 even though the PCI bus cannot even reach SATA150 speeds. This can cause data corruption in operating systems that do not specifically test for this condition and limit the disk transfer speed.
