Help~!! P4t-e & Pc-1066 Rdram

Hi

I got a P4 1.6 Northwood with P4T-E + 2 x PC-800 128MB RDRAM (about 2 years old )

My question is

1. Does P4T-E support PC-1066 ? i just got the latest BIOS from ASUS but it says nothing about it
2. Should i stick with PC-800? i only got 256MB at moment....and i am looking to upgrade it to 512MB.

thank you

All depends... if you have CYP clockgens on your mobo, it should work just fine! I run PC1066 rimms which I was able to oc to 1136 (142FSB)

The sticks will work fine, the only question is whether the system is actually able to attain the 133Mhz/PC1066 speed, as the other guy mentioned. But there are no compatibility issues AFAIK.
