Asrock x58 extreme oc question

post #1 of 7
Thread Starter 
So I just upgraded my ram and I am knowing running 12g skill 1333. Well since the upgrade I can no longer even hint at oc or the board fails to post. When I was just using 6g I was stable at 4ghz at 1.23v. What's the deal?

There's a general rule of thumb, that having more sticks of ram will make overclocking slightly more difficult. That's why it's enforced to use less sticks with bigger capacity per stick.

Try backing off the timings of the ram a little.

Is that 12GB comprised of 3x4GB DIMMS, or 6x2GB DIMMS? Running six DIMMS is going to reduce your overclocking potential on a lot of boards.

p.s. You win the award of the week for giving as little relevant information as possible. It would help to mention what CPU and RAM you have, and the BIOS settings you're adjusting to get your overclock. Also, if you've updated the BIOS on your motherboard.

 What CPU? Also, Don't forget to keep you RAM multiplier in sync.

Only thing I can suggest is pull out the 3 DIMMs you just added and see if you can still support your previous OC. If you can, then the memory controller and overhead of 6 DIMMs is probably what's holding you back.

You could try bumping up the VCCSA / Vccio a little bit to see if it helps, sometimes it does with more DIMMs installed.

I assume you're overclocking by upping the bus speed. The stock bus for that 920 is 133, with the 20 multiplier, that gives you a 2.66 cpu. So if you wanted to OC it to 3.33, you could simply up the bus speed to 166, but for your RAM you'd have drop the RAM multiplier to 8(8*166=1328). Easy peasy.
