Kingston HyperX KHX6400D2K2/2G

[zapbuzz]

Hello everyone.

I have installed Kingston HyperX KHX6400D2K2/2G (kit of 2 sticks) on my Asus P5N32 SLI PLUS motherboard.
It has the latest stock BIOS from Asus and currently runs at 667 MHz at post boot whereas its supposed to say 800mhz.
In the bios overclocking menu I have come across a memory settings sub menu with the following options that are currently set to automatic:

tCL (cas latency)
tRCD
tRAS
Command Per Clock (CMD)


**ADVANCED MEMORY SETTINGS**

tRRD
tRC
tWR
tWTR
tREF
tRD
tRFC
Async Latency

In the overvoltage menu there is a memory voltage sub menu with the following options:

DDR II Conroller ref voltage
DDR II Channel; A Ref voltage
DDR II Channel B Ref Voltage


If someone could answer the correct settings so my memory clock will show 800 MHz at boot up it would be much appreciated.

I have a 2.6 GHZ Intel quad cpu installed Q9400 core 2 Quad with 1333 fsb
Thankyou.

Your ram running at 667 is right since doubling it will reveal that you get 1333MHz which is your processors FSB. If you want to get the full performance of going with DDR2 800MHz then you're going to need to overclock on your CPU side.

The page you've ended up is where ram latency's are input which, for all intents and purposes, is not the place you should be to fiddle around with FSB's. To which I'd say it's best you don't attempt to do so.
