Geil Overclock

[Mark403]

I have :-

GeIL 2GB (2x1GB) PC6400C4 800MHz Ultra Low Latency DDR2 Dual Channel Kit
EVGA 680i Motherboard

Now i understand this Ram runs at 800mhz frquency.

now in the bios i can change the DDR frequency (actual frequency = DDR / 2).

When adjusting this setting it increses the frequency shown in CPU-Z, so a DDR frequency of 900 is 450mhz frequency in CPU-z.

the max DDR frequency available in the bios is 1400, this would give a 700mhz frequency in CPU-z.

my question is, how do you get to the 800mhz frequency (1600 ddr frequency in bios) ? ??

is the 800mhz shown in the Bios (400mhz in cpu-z) correct for the ram, or am I indeed supposed to get it to 1600 in bios (800 in cpu-z) ??

thanks

OK, i think ive just made 800mhz memory run at 900mhz, i think CPU-z isjust displaying it wrong or im reading it wrongly (the bios is the correct clock but CPU is the DDR / 2 value).

I say this becasue 3Dmark06 says im running ram at 900mhz.

yeh i was reading it wrong, on my Bios the the CPU clock of 200mhz is displayed as 800mhz (QUAD data Rate)

using the the same reasoning with the ram, i thought the 800mhz displayed was only 400mhz (DOUBLE data rate), but 800mhz shown was actually what the ram is supposed to run at.
