Overclocking 1333MHz RAM

[PlaneGuy]

Hello, I was wondering if I would be able to overclock my 1333MHz RAM to 1600MHz. I have 16GB of Kingston HyperX. I've never overclocked before, so would someone be able to tell me what to change and what to change it to?

Thank you.

Make sure the voltage is set at 1.5, and just set the RAM to run at 1600Mhz in your BIOS.
Download memtest86 and install it to a USB flash drive, boot from it and run at least 8 passes. If it passes without errors, you're good to go! If not, you probably won't be able to run the kit at over 1333Mhz, or the timings aren't set right.
Let me know how you go!

Easier than I expected! I'm running Memtest now, but across 16GB, it'll take awhile lol. I'll reply back when the tests finish.

 

[Alex Kelly]

Great! Best of luck. Looking forward to hearing how it goes.

 

[PlaneGuy]

Ok the tests just finished. 8 passes and no errors! So is everything good to go now?

 

[Alex Kelly]

Yep! Sounds great. PM me if you come across any issues in Windows.
Please consider picking my answer if you're happy with my advice.

One last question. In the BIOS it says the memory is running at 1600MHz. BUt when I look at CPU-Z, it still says it's running at 1333MHz. I'm supposed to multiply the DRAM frequency (666.5) x command rate (1T), correct? But because it's DDR3 do I change the 1T to 2T or 3T?

 

[Alex Kelly]

The command rate is irrelevant to the frequency, 1T is the way to go.
Very stange that CPU-Z reports it as running at 666.5Mhz. Should be 800! Do you have the latest BIOS? Sounds like the settings aren't sticking.

I have the F10 BIOS and the only newest non beta BIOS is the F11. There is a F12I and F12W but they are beta BIOS it says. I did restart the PC because I'm overclocking the CPU too and in the BIOS the memory speed was still 1600MHz.

 

[PlaneGuy]

After checking the BIOS again, it says the memory multiplier is 13.33. I don't have an option to change that. Next to it it says the memory frequency is 1600MHz. And after each restart the memory frequency does stay at 1600Mhz.
