[Solved] My memory not running at 1066

Could anyone please help me i have the cl6 team xtreme 4gb 1066 kits and i have the ma785g-ud3h i change the setting in mit tweaker memory clock to 1066 but i checked cpu-z in was 400mhz in cpu-z and then i tried changing the timings to manual by 6-6-6-18-2t and left the voltage in auto but it is still the same. and also there are other settings in the timings menu but don't what they are some like Trwr something timing so i left as they are well i hope u can help out

Congratulations, you have nothing to worry about.

533 x 2 = 1066

Hey thanks man u were a big help i mange to get it to 1066. I run a bunch of test it's stable. oh btw i do live in oz and about the ma785g-ud3h yeah it's a good board alot oc features i did'nt actually buy it i won of the tweaktown.com giveaway and i used the amd phenom II 550. i also unlocked the extra cores on it, it's running pretty stable.

The most likely cause of not seeing 1066 speed when you POST or 533/1066 in programs in Windows is because your RAM voltage is set to Auto in the BIOS.

Set all the timings back to Auto for now - they don't affect the basic memory type. The specs I've seen on your RAM:

# CL-value: 6-6-6-18-2T
# Working voltage: 1.8V ~ 2.0V

The 2.0V is necessary to achieve 1066 mode. With that set properly in the BIOS, the computer should then show 1066 when it boots and 533x2 or 1066 in programs.

Go into the BIOS, set timing back to Auto and turn Voltage to Manual. Only change the RAM voltage. If the default is 1.8, then add +0.2 to it.

Then, you can look into changing the timing factors. The other number you're looking for is likely 24 btw... the tRC

6-6-6-18-24-2T -- generally the tRP and tRAS added together.

CL - tRCD - tRP - tRAS - tRC - CR


BTW, I almost bought your board, decided on the US2H instead. How is it working out? And what processor did you get? I'm guessing you're in Oz or UK - that brand of RAM doesn't seem popular in the US.
