one of my ram slots on my laptop broke so i only have 1gb ram now i check its speed and it says 333mhz, it was 2gb dual channel 667mhz, now i wanna upgrade to 2gb 800mhz do u think it will support it? i tried hp but they dont tell me

It will support it, though it will run at whatever speed is set in the BIOS.

I would suggest you get a 4GB dual channel kit if you want an upgrade.

i cant have dual channel one of my ram slots broke so i can only use single channel

Ohhh, I misread, I thought you meant one of your sticks. I would suggest getting it fixed, if possible.

nah cant afford it
