hi guys, just upgraded from 800mhz 2GB (2 channel) to: 1066 mhz 4GB,
(my mother says it can support DDR2 1066)

After installing the ram i notice on the "post screen" it said DRAM clocking = 800 MHZ,
so after a few google searches i done this:

changed RAM voltage to 2.10000
changed the RAM frequency to manual and set it to 533MHZ

after that, "post screen" showed DRAM clocking = 1066,

does this mean i am running 1066 mhz ram now?
i did not change any latencies because in my bios theres 20 settings rather than the few 5 5 5 5 15 or watever, so didnt change it incase they werent the right settings to adjust,

thanks guys, gold badge up for grabs here :-)

Yes, if it says 1066, that indeed means that it is running at 1066.
If it is stable and you have no problems, leave the timings alone.

You don't give the model of the RAM or motherboard. If the RAM needs 2.1V for 1066 mode, you're fine. Did you try changing just one setting?

That is, leave the RAM to auto and use 2.1V... or vice-versa? Might not need to give it all that voltage or manually change freq.

Ya know, I never even ASK my mother about my system.


(OK, I'm sorry, that was un-called for...)

sorry , its actualy on box says 1.9v - 2.0v, its silicone power X-power, so i changed from 2.1v to 2.0
(now writing in text is pink not red (for voltage)

for some reason when i select an auto overclock profile of only %7 i get an overclock fail,

could this be my power supply not having enough juice?

500psu

m2n68 MB
4890 OC
AMD 720 BE x3 core (black edition phenom)
x2 HD's
x4 case fan's

used to run fine with the 800 MHZ at cpu over clock %7 , possible new ram uses that little bit extra power to not have enough juice for cpu?

-getting new powersupply today anyway, want bit more room for additions)

I'm no OC guru, doubt I can help you there. But remember, 7% of 1066 is a larger number than 7% of 800.

And the RAM may like the 2.1V rather than 2.0V when OC'd.

I doubt PSU, if working correct, is limiting you. The Watts used by RAM is tiny. Here's a handy calc for it - I was surprised at how little my vast # of drives drained the PSU.
