Laptop memory won't run at 800Mhz

[MindZiper]

I'm on an ASUS F8 Sp-X1 with an upgraded CPU (T8300).
I just upgraded it's ram to two 2GB PC2-6400. But the RAM runs at 333Mhz.

I checked BIOS, but it has no memory configurations or anything. What could I do?

PS. Crucial scan says my laptop does in fact support PC2-6400

bump?

Well firt off , ddr stands for double data rate so that 333 actually equals 667mhz, wich is rather standard for laptops

i reckon it does let it run it just not at those speeds, like its doing now. I dont know what chipset your laptop uses but with that you could find out if it actually can run at tha speed

You are right. I just checked everest and indeed it says 667. Thanks.

systems need to run memory in ratio so reguardless of 800mhz (400x2 aka Double Data Rate - DDR) the system is running it the way it should.

Forgot to multiply the speed by two, but it was still running under what I expected. I'll never trust crucial scanner again. Everest seems to be more accurate. At least I paid about 6 dollars over the slower RAM. Not that much of a difference.

i have same problem too...but already search that laptop much stable at 333MHz than 400MHz and sometimes even i use the 400 it only run on 333
