RAM not getting the right frequency

Arc Rainman · Apr 22, 2015

Hi, after buying the 16gb G-skill Ripjaws 1600Mhz, I noticed on my BIOS that I'm running a default 1.1GHz. After that I immediately changed it to 1.4Ghz.

Now the question is: What maximum frequency is allowed for me with this RAM?

My specs:
HX650 PSU
M5A97 LE 2.0 MOBO
F3-1600C9D-16GXM Gskill 2x8gb
FX 8320 8-core OC'd 3.8 ghz
840 evo SSD 250gb

EDIT: 1.6Ghz I meant.

Sorry, that was just a typo. But do you get the idea?

1600mhz=1.6ghz seems to be running at the right speed.

Unolocogringo :

No, CPU-Z shows NB Frequency: 2383.8Mhz, and BIOS says: 16GB RAM 1.4Ghz.

You are doing FSB overclocking. You will need to change the ram multiplier to get it close to stated speed.
If changing the multiplier runs it above 1600 you may need to up the voltage to the ram slightly or loosen the timings to get stability.
Different chips ,whether CPU, memory, or GPU, will overclock differently. Trial and error is the only way of knowing what each piece is capable of.

Enable DOCP, or manually input DRAM Frequency, timings, and voltage.

I already enabled DOCP and this is what I get.

EDIT: I'm supposed to have 9-9-9-24 latency aswell. Gskill model: F3-1600C9D-16GXM

You are running at the right speed.
DDR or double data rate sends 2 bits per clock cycle for an effective rate of double bus speed. 800x2=1600.
You now need to go into the bios and set CAS timings manually.

gskill support · Apr 23, 2015

Did you select Profile 0 or 1? If you do that then it will input timings for you. Otherwise, you can do it manually as well.

I chose Profile 0 I think. Cas timings are good now, but it seems as though the cpu temperature rose up by a few degrees while on idle or when I'm watching something on netflix. It now stays at 44*C and I can remember it was down below 40*C.

Is this normal?

gskill support · Apr 24, 2015

Yes, the memory controller is on the CPU, so as you boost frequency it can slightly increase temp

Sounds like everything is good, enjoy!

If I let the OC Tuner do it its way, how much difference in speed should I feel? Seems like my temperature with 1600Mhz would fry my CPU. I reached 66*C by just playing Dota 2 , and only Dota 2 opened- nothing else.

Depends what the OC Tuner sets everything to, but generally any auto OC is not preferred. You can easily manually OC and set things properly yourself. DDR3-1600 is standard, so it's not going to fry anything. You should check CPU installation and thermal paste application if CPU is getting hotter than it should.
