[Solved] RAM running at 1333 instead of 1600

post #1 of 7
Thread Starter 
I'm having trouble getting my memory to run at 1600.

Motherboard - AsRock Z77 OC Formula

Memory - Corsair CMZ16GX3M4A1600C9 16GB

I have set the XMP profile in the bios, i have also tried manually changing it into 1600, and i have also tried changing the voltage from auto to 1.5v.

I have attached a few screenshots of the bios and CPUZ, any help is greatly appreciated. ( Sorry about the bios pictures, also there are loads of memory options available to tweak )

So what is the problem? Is it not stable?

That's really strange, it sure does look like your BIOS is set for DDR3-1600 and the XMP profile is selected. I see no reason why it shouldn't be running at DDR3-1600 speed. Maybe double check to ensure you have the latest motherboard BIOS installed?

[Edit: Looks like you have 2.00 BIOS installed, that appears to be the latest version on ASRock website]

What are the options under "DRAM Reference Clock"? It's set to Auto right now.

Thank you for the quick response, only two options are available under the DRAM Reference clock which are - 100mhz and 133mhz.

I've looked up this problem and nothing seems to help, I've contacted AsRock but they seem to be on vacation all year round and never reply.

I have tried resetting the bios, and re-seating all the memory modules ( Testing them one by one ) but nothing seems to get it to run at 1600.

What version of the Intel Management Engine (ME) is running on your board (integrated in your bios)? I've seen issue where a bios upgrade doesn't correctly update the ME, which causes these kind of issues (Ram and CPU settings not working). I don't know how to update it on your board manually, only on my ASUS x79 board. Here is a link to give you an idea of what it entails. The only difference would probably be a different version of ME as the one in my link is for the x79:

Thank you for the response.

Before trying to update the ME, i decided to re-flash the bios to the same version. Turns out this fixed the problem !

Thanks !
