How to adjust AMD Bios to clock Corsair Vengeance appropriately??

Greetings All !

I just purchased and installed the following:

Corsair Vengeance Series 8GB DDR3-1866 (PC3-15000) CL9 Dual Channel Desktop Memory Kit (Two 4GB Memory Modules)

Model: CMZ8GX3M2A1866C9

Now, when researching RAM, I recalled seeing some folks complain that this ram defaults to 1600 instead of 1866... but several folks would say "Oh, just adjust it in your BIOS"... and that did the trick.

However, I'm not exactly sure WHERE in my AMD Bios I'm supposed to find this... and I'm not exactly sure how to know when it's running as 1866 when I'm done?

I saw that my AMD BIOS had an option to "Enable XMP Profile", which I did. The BIOS says the ram's running at 1600.

And GPU-Z shows me the following:

So, I'm thinking that since this shows 800 MHz, that's half of 1600, so that's what the RAM is running as at the moment, right?

(Even though it says Slots 2 and 4, the motherboard manual says to use the blue ones first, which is what I've done. Motherboard is an MSI 970A-G46, if you're curious.)

What's funny is, Windows itself now seems to take 4 times longer to load then when I was running a mismash of 2 sets of 2 GB DIMMS that are a couple of years old... a set of 2 OCZ's and 2 Corsairs. And this is a fresh install of Windows on a brand new SSD drive...which I installed a few days ago. Odd....


Thanks!

What CPU? Need to enable XMP then select profile 1 or 1866, thing you may have XMP enabled but have freq on auto which will prob be 1600 - also possible the CPU can't carry 1866 - normally want a FX 8xxx or 6xxx CPU......and it may need the BIOS updated, MSI isn't all that fast with BIOS updates

Well, I went back into the BIOS and, on a hunch, I de-activated the XMP Profile thing... and then chose the "DRAM Frequency" option. 1866 was in there so I selected that, saved, and rebooted.

The BIOS now shows it's running at 1866... and CPU-Z... on the "Memory" tab... for "DRAM Frequency"... says 933.3 MHz. So, I'm thinking that must have done the trick?
