Advice on memory.

All of those are supported by your memory. It is apparently JDEC #6 running by default from what your memory tab said. Enable XMP in the BIOS to get the last column, which is faster.

Huh that's odd, because I definitely remember enabling XMP right after I built this. I'll have to check in the BIOS again and get back to you guys.

I didn't realize you had an AMD. It is probably called DOCP on AMD rather than XMP (on Intel).

There was an XMP setting and it was disabled, so I clicked on it and there was one profile, so I enabled it. This is what I have now:

This what I had before:

Little late to the party but the new G Skill Ripjaws I just installed are a dream.

My DRAM frequency went from 1066.4 MHz to 1799.6 MHz. I'm still not sure what the actual amount should be because I can't find it anywhere, even on the G Skillz page. I'm assuming what I have now is better than before, but in what ways would I notice this increase?

Maybe it's this: F4-3600C16D-16GTZRC - Specification - G.SKILL International Enterprise Co., Ltd.

I don't know why CPU-Z may have omitted the D. The XMP timings are the same.

I believe that in Gskill's naming convention F4 RAM is DDR4, 3600 is the frequency, and the first 16 is the latency.

I'm a little surprised that the RAM voltage wasn't set to 1.35V, if you are actually running the XMP in the screen shot (post 44).

Can I set the RAM voltage to 1.35 ? I'm assuming that's done in the BIOS. I took a screenshot of the SPD, if that helps:

It is dual channel ranm so when it says 1799.6 it is twice that, or 3600 MT/s, just as specified. (MT/s is the same as saying MHz, it is just MT/s is the more proper unit.

Setting bit to XMP should have automatically set the voltage to 2.35

Correction: 1.35

Typo. I'm at a wine tasting at a bar and the keyboard on iphone iOS stinks! Lol

Based on your usage patterns you probably don't need more memory unless you are going over 90% utilization.

You could.

But I'd expect it to be set automatically when you choose the XMP.

If the RAM is actually at 1.2V and is stable, it may not be necessary.
