RAM going 1066 instead of 1600

[robot_man]

i have
750 Watt psu
i7 920
Jetway BI-600 from the sub $200 review

Patriot memory

4870 graphics.

My ram only runs at 1066.
I've tried setting the timings manually but that just crashes it.
i'm out of ideas so if anyone has any suggestions please let me know.

You have to change the default memory multiplier from x8 to x12.

For timing, you may need to also adjust the timing along with the voltage, to the specified manufacturer spec.

The 920's "standard" memory clock is 1066. The reason why most peeps buy 1600 is that when you OC the 920, the memory goes up proportionally. At the default memory multiplier of 8, and a base clock of 133.33, your memory will run at 8 x 133.33 or 1066.66 Now to change it to 1600, you have to change the multiplier to 12 (12 x 133.33 = 1600).

However that leaves you with a dead end as at this point you can't OC your 920 since increasing your BCLK now put you past 1600. For example, say you want to go to 4.0 GHz....one option would be to use a BCLK of 200 with a CPU multiplier of 20 and a memory multiplier of 8

200 x 20 = 4000 MHz (4.0 Ghz)
200 x 8 = 1600

how do i change* the multipler

The motherboard owners manual will explain how to manually set the RAM speed/timings/voltage. That includes telling you how to change the RAM multiplier.
