I have a Sony Vaio PCG-K33, i've added two 512 MB PC-2700 DDR 333 chips. The laptop will only recognize them as 256 a piece. I exchanged the ram for the same that was purchased from Newegg. And it they still only read 256 per chip. I've checked and my Vaio supports up to 1 gig total and recomends PC-2700 DDR 333. Any suggestions as to why this would be working? If this matters i'm running XP Home. Is this part of the issue?

Did you run a refresh and firmware update of the BIOS?

Yes, I checked all firmware and system updates and it's all up to date.

Not counting SP3, but do you at least have SP2 and the other hotfixes as recommended by MS?

You should be using according to Corsair

Memory Type DDR-266 (PC-2100) SODIMM

Size 512MB

Latency 2.5-3-3-6-2T

Format 200-pin SODIMM

Heat Spreader None

If the RAM you have purchased doesn't meet these standards it will not work with your system. By the sounds of things you have got some High Density RAM here which is [b]Not Supported[/b] by this system you require Low Density RAM for this unit.
