Memory question

[jhonsonlee]

My PC is Compaq Presario SR5080CF CTO -- Intel C2D E4300, 4 DIMM slots

Slot 1. DDR2 (512MB x 1) 667MHz
Slot 2. DDR2 (2048MB x 1) 667MHz
Slot 3. DDR2 (512MB x 1) 667MHz
Slot 4. DDR2 (256MB x 1) 533MHz

I would know whether the DDR2 (256MB x 1) 533MHz will speed up my pc or drag down the performance since it is 533MHz?

Dude you can get 4gb (2x2gb) ddr2 800 for $30 after rebate. Dont try to run mixed crap. I bet they are all different timings too.

Use promo code EMCLNNP26 for another $10 off.

You should also warn the OP that those modules won't work in his Compaq.

It will drag down your PC. Is the 2 GB module detected as 1 GB or 2 GB? I believe that the maximum size is 1 GB of DDR2-667. Ideally you'd replace that module with 2 x 1 GB modules.

Your MB supports up to 4GB of memory but only as 4 x 1GB. It will not support a 2GB stick in one dimm. Whatever the slowest speed is of any one memory module is what the MB will set the other memory modules too. So if you have 3 modules at 667 and you add one at 533 they will all run at 533.
See links below to your MB support site.

Memory slots: 4 DIMMS
Maximum memory: 4 GB* (4 x 1 GB)
*Actual available memory may be less

=======================================================

You all are wrong it support (1 x 2048MB) in a slot it detected all the memory

PC BIOS, Win Vista & XP detected total 3.25GB of memory PC BIOS detected also Win Vista & XP.

Great, the RAM should run at the speed of the slowest stick.

Download CPU-Z and look at the memory tab to confirm. You can also look at the SPD tab to see the true timings of the sticks as loaded into the serial presence detect area of the RAM by the manufacturer.

I'd love to see this frankenstien machine lol
