RDRAM help needed

Stky10

Howdy,

I'm trying to buy some RDRAM to upgrade my PC, but I'm having difficulty in deciding what type I should upgrade to.

I seem to have a PC700 184Pin stick.

However in looking at komplett

They only seem to have PC800 sticks. So is PC700 compatible with PC800??, or if I remove my PC700 stick, what are the chances that a PC800 stick will be compatible with my motherboard??, or would it just be better to find somewhere that sells PC700 sticks??.

The differences between PC600, 700 ad 800 is only how the fast motherboard runs the ram. It's live when you stick PC133 into a PC100 motherboard, the PC133 will run, just slower then it was rated to.

If you stick PC800 into your motherboard, it'll run at either PC600 or 700.

But your system cannot make use of all the bandwidth your ram provides. Look into selling your current CPU and mobo, then buy a cheap 2.0GHz Celeron and a cheap RDRAM mobo to go with it, shouldn't cost more then €100 when you subtract the money you got form selling your current CPU/mobo. This will allow you to take full advantage of the ram and cpu and your system will fly.

Actually I've done more checking, and most places say that PC800 is only suitable for Pentium 4 MoBos, and mine aint that.

Looks like I'm gonna have to find someone who sells PC700 gear.

I've seen at least one case where a PC800 RIMM was not accepted by a motherboard in place of a PC600 RIMM.
