memory overclock

[rallyslag]

when i overclocked my cpu a while back i left my memory on auto, how do i find out if its over or under clocked ??? to me i looks underclocked , the mb is a asus p5w dh ,wich suports 800 mhz memmory

Multiply the DRAM frequency by 2 (since its ddr) to get the actual speed. So in your case thats 356.5 x 2 = 713MHz So its underclocked

That what i though,been like that over a year now

I,ve just changed it and o/c the memmory , i take it this is about a 20% o/c on memmory, being kingston 1066 mhz hyper x sticks . hopfully ok . I will use orthos on the memorry to make sure of stabillaty

You lowered the FSB : DRAM ratio so now the memory is at 534.6MHz You are supposed to increase it. Try something like 5:6

I thought My Fsb being 1425 then a fsb;dram of 4;3 would be 1425:1068, so memorry running at 1068

I did set my DRAM in bios manually to 534 ?? ddr2 534 x 2 = 1068

Thanks i got it now . weird my maths worked for me then but totally wrong )

i now got 4:5 which gives 445.6 mhz x 2 =891.2 mhz . On a 800 mhz motherboard that will do for now ..

again thanks
