Me again,

Been looking at different thing on my computer and in CPU-Z found my ram speeds, but i cant work it out. Isn't most ram speed at 667Mhz ? and mine says it's running at 333Mhz

Is this wrong or is it just that slow ?

Also i think i saw somewhere that it's multiplied by 2 so 333Mhz x2 = 666Mhz. Is this how to workout ram speed ?

Thxs for any help.

exactly

my mem bus is 250 and my ram(ddr1) is running at 500 after being doubled

DDR double data rate

now the next step is understanding cas wait states

when they came out with ddr2 and your ram was pushed to 667 they had to raise the cas to 5(higher here is bad/slow)

my premium crucial ballistix ram running at 500 has a cas 2.5

premium ddr2 ram runs at 800 or higher with a cas 4 or even a cas 3(very best)

No. Try not. Do... or do not. There is no try.
