hi guys i have a crucail 2 x 1 gb ballistix dual channel memory pc2 6400 800 mhz

they are all on auto is bios and memory clock on bios is auto but it says ddr 2 533 even though im sure mine is ddr 2 800

on cpu z it shows 267 mhz


question 1, shall i set them manually to what it says on the ram sticks 4 4 4 12 or leave them auto

question 2 shall i change memory clock to ddr 2 800

i have done this once i do it

on cpu z it shows 401.9 mhz

is this right is that what my ram should be at?????????????????

or should it say 800 mhz?????

or shall i choose memory clock in bios to ddr 2 1066 and change timings to 5 5 5 15

Yes. Cpuid shows about 400 for ddr2 800 (pc6400). I wouldn't overclock it.

Your memory will say dd2 400 or close to it in cpuz, that means 800mhz effective, so that's correct.

I recommend setting the timings and voltage to manufacturers specifications as well.

DDR2 is double pumped, so for every cycle it gets two calculations.

therefore at 400mhz operating speed it has an effective 800mhz. so yup, this is correct. you may be able to OC it to 533 and get 1066 effective if you are lucky ;)

I am not a proponent of overclocking memory. There is no practical benefit to running memory faster the FSB freq:mem clock ratio of 1:1 as reported in CPU-ID.

For my Core2 systems (Gigabyte), I change the System Memory Mult. from AUTO to 2.0 (DDR2 memory) and let the memclock rise with the FSB frequency.

Leaving the SMM on AUTO can limit your overclock because the memory will reach its limits before the CPU does.

so because it say 267 in cpu z

shall i change it manually to ddr2 800 in bios so it says 401.8 in cpu z ?
