I don't think my RAM is running as at the speeds that it should be

[auto-zxon]

I just ordered 16GB of of G.SKILL RAM (you can see it here http://www.newegg.com/Product/Product.aspx?Item=N82E16820231611&Tpk=20-231-611) and CPU-Z says its running at 460MHz, and this seems low? I also don't think the timing is correct. I really don't know what I'm looking at though when CPU-Z gives me information. I read that you can go into the BIOS and alter the timings and frequency of your RAM, so if that is what I should do I have another problem there. When I enter BIOS, the memory options are unselectable, and I can't find any options anywhere else in the BIOS. Maybe I'm missing something though. My PC specs and CPU-Z information is in the picture attached. Thanks in advance for your help, if you can provide any!

DDR3 RAM doesn't run this slow, especially stuff that's supposed to run at DDR3 1866. The timings look amazing, though. Just posting to inform you, this one is above my skill level.

I imagine the timings are that tight due to the fact that the RAM is only clocked at 920MHz (460 x 2). Is that the same speed shown in BIOS? Even un-touched in BIOS, the RAM should be running at 1333MHz (667 x 2).

In BIOS/AI Tweaker you should be able to set the memory clock up to your 1866MHz.

Do you have the latest BIOS or at least a version that supports the 6300

Yeah that is what it shows in BIOS. I wanted to up the speed, but I couldn't select that option. It would only cycle through other options.

And to Tradesman, I believe I do. I didn't know BIOS was something you had to update

It looks to me like it's configured as DDR3-933 (466Mhz clock) rather than DDR3-1866 (933Mhz clock)

Well that's half the advertised speed. Is there a way I can get it to run at what I expected it to run at when I bought it?

CPU-Z will always show "half the speed". You have to mentally double it since it is Double Data Rate memory. CPU-Z will read ~933 MHz when it is running at it 1866MHz speed.

No, it's running at 933 Mhz, not 1866 Mhz. The data rate is 1866 MT/s. Transfers and cycles are different measurements.

Good point and understood. I was just trying to simplify by using its 'effective' speed. Apparently, RAM manufactures like to simplify too. Hence the "1866 MHz" label on the RAM. 😉

Indeed and I'd wish that they'd stop that. Mislabelling measurements to fight a marketing numbers war drives us engineers crazy. It even bleeds over into the software world where some hardware development products seem to use configured data-rate, device speed-grade, configured clock frequency, and compatible clock frequency interchangeably. It's infuriating!

No such mislabeling with G.Skill!
