Greetings,

Recently I added a second pair of 2GB Dominator sticks to my setup for a total of 8GB. As expected, I was unable to run all four sticks at their stock (1066MHz) speed at the stock voltage. Rather than risk damaging them with overvolting, I decided to underclock them to match my FSB speed. I was able to tighten the timings to 4 4 4 12 from the stock 5 5 5 15 to make up for some of the speed loss, and I hope to be able to lower them a bit more.

Here's the question, though. With the lower clock speed and given the tighter timings, should I reduce the voltage from the stock 2.10v?

The chips were designed to run at 2.1v so it's pretty pointless to undervolt them. I don't know about you but I've never heard of ram overheating.

Well, thanks again for the advice! It seems like that did the trick!



Northbridge voltage set to 1.45v and all four sticks are running at stock speed and voltage! That gave me an extra 1GB of bandwidth for a total of 5GB/s!

Thanks again! +REP

Nope, those are Powerchips and they don't scale with voltage. 2.0v 5-5-5-15 should get you to 1066 or higher without issue. However your mobo may hold you back.

If you are running 800 FSB with 4,4,4,12 you should be able to drop the voltage to 1.8v. According to the timing tables mine came with.
