Set ram to 1066 when it's running 800!
« on: 31-January-09, 11:37:55 »

Hi there,

First of all, DDR2-1066 is ONLY supported with a Phenom AND 1 or 2 sticks (2 sticks see manual for dual-channel slots!).
Second, go into the BIOS and set memory from Auto or 1:2 to 1:2.66, no other things need to be done.

That's it!

Ps. if your memory still won't do it, then it's probably NOT real DDR1066 memory.
Ps2. if your memory need more then the default voltage, best set the voltage to specified.

Small note: DDR2-1066 with four sticks will work fine, as long as you have single sided memory modules. Single sided meaning they have only one rank, for example eight 1 Gbit memory chips (a 1 GB memory module) or eight 2 Gbit memory chips (a 2 GB memory module).

Some BIOS versions apply higher latencies when using the 1:2.66 ratio, I get the same latencies...

K9A2 Platinum, AMD Phenom II 940 Black, Kingston HyperX KHX8500D2K2/4G (that's two sticks of 2Gb)

Kingston reckon this stuff's tested to run 5-5-5-15 @ 2.2V and guess what? It does too.......

Please stop discussing timings, it's only about the setting to run 1066 and 2 sticks, nothing more.
