I am trying to overclock a computer I just built, and I noticed that when I dial down the memory speed the motherboard sets the wrong timings. I want to set them by hand in the bios, but I am having trouble figuring out what all the terms mean.

The RAM is :G. Skill l9-9-9-24-2N @ 1600 MHz

Here are the bios screenshots:






Can anyone explain to me what all the acronyms stand for and what I have to change from the default to the proper values.

By the way, this is what CPUZ shows for the RAM:

---

First....you have to change the master setting from 'auto' to manual.

Otherwise the bios will override anything you put in on every reboot.

"Time is simply the mechanism that keeps everything from happening all at once."

And This tutorial might help explain a few more details.

So what is the DRAM Timing mode? I can set it to DCT 0 or DCT 1 or Both.

If I set it to Both, the options shown in screen-shot 2 double, i.e. I get another set of all of the options.

I'm not 100% sure, because I don't have much experience of the Biostar bios, but I think that you can have 2 sets of timings for the ram. If it was set to DCT0 when you first looked, I'd leave it on that one.

Set the memory timings in the bios manually, as you have already done, then you should be able to set the memclock to DDR3-1600. No point in setting the rest of the timings if you can't change that one.

Then save and reboot.

It should boot up right into windows. CPUz says that you should be able to run the memory at that speed without increasing the voltage, so it should be stable from the off.

The only problem you might have is that the motherboard doesn't like the memory. I use ASUS motherboards at the moment, I find them rock solid, and they quite often produce a memory QVL list with memory that is tested and guaranteed to work with the motherboard.

Give it a go!
