Help me get the best out of my memory!

[goudwijzevis]

Help!
Here's what I'm using:

ASUS M4A78 PRO
2x 1GB Kingston Hyper-X 1066MHz DDR2
Phenom x3 720 Black edition.

The problem is, when I manually set the memory speed to 1067mhz (1066?) the computer restarts and I get a 'Overclock has failed' error. I'm sure someone on this forum has had the same problem, I'm unsure as to what settings I should be using.

Have any of you with this motherboard managed to get the memory running at 1066mhz?
If so what settings are you using?

Overclocking the CPU has been easy, windows experience gives my cpu a score of 7.1, it gives my memory a score of 5.1

I've just noticed this:

"Due to AMD CPU limitation, DDR2 1066 is supported by AM2+/AM3 CPU for one DIMM per channel only."

If it helps, I have 1gbs stick in the two yellow slots A1 and B1.

try 1 yellow and 1 black, that board apparently has had mem issues 4 a minute, run it at 800mhz, make sure its in dual channel

Manually set both the timings and voltage in the bios.
