Achieving 4ghz with a higher bclk and lower multiplier

post #1 of 4
Thread Starter 
If I wanted to achieve 4ghz and keep my ram at 1600mhz. I'd need a bclk of 267 x 15.

At the moment I'm running my bclk at 200 and multiplier at 20.

If i increased the bclk by 67 mhz, would this require a much higher QPI link voltage? Or would it also require a higher vcore as well.

Why are you trying to go with a higher BLCK?
it's usually around the other way.
Try 191x 21

I can't imagine that you'll get that kind of base clock, some boards apparently can't make it past 200.

I've never pushed a board that far but as I remember I read people talking about 240 base clocks under LN.



Either way you will run into stability issues, and anyway, the speed of RAM isn't just based on its MHz.

Slower clocks with tighter timings can produce faster RAM, so even if you are underclocking the RAM, you could tighten the timings on it and possibly produce a better result.

Yeah, for the moment I've hit the sweet spot with my ram. It won't really go any higher than 1600mhz, but I've managed to get the timings down as far as they would go.

I was just hoping for a bit more out of the NB to get a bit more out of the ram, but I suppose going over 200 bclk will cause me trouble, hehe.

Also, for some reason every time I boot up my ram alwasy sreverts back to 2T command rate, when I've set it to 1 in the bios. It'll show up at 1t in cpu-z then after a restart it'll go back to 2t.
