Hi, please see below screens from CPU-Z, is my RAM running at 1866? i have 4 sticks of 4GB Corsair Vengance, two are low profile and two are the ones with the lovely heat spokes (or whatever you want to call them). I just purchased the two low profile ones thinking they were going to be the same :/

I did some fiddling in my BIOS based on info from here (changed XMP to profile 1) but just need to check as all these numbers are meaningless to me!

I have attached some images below from CPU-Z trying to show to two different cards

UPDATE

So it seems that the XMP setting have gone back to default and it seems to be running at 1338 now :/ I try to set it to profile 1 again but on reboot I get a message telling me to use best optimised settings as there was a problem.

Any ideas?
 
Mixing multiple memory kits and setting XMP is not likely to give you good results. It appears you are running at SPD memory settings of 1333MHz. You should manually set the memory clock to 1866MHz speeds. Corsair won't guarantee that mixing multiple kits wil work together, even if they have the same part number. You may need to use 1600MHz memory clock speed for them to work together.

Cheers Calvin,

Understood, not 100% sure how to manually change the speed, do I have to change the multiplyer?

May take a pic of the bios setting on my phone and post for some guidance.

Cheers

UPDATE

Okay, I know I need to set the multiplier to 9.33 for 1866mhz (which it didn't like) What multiplier do I need to try 1600mhz?

Thanks for the reply.

I am running an AMD FX 6300 on an Gigabyte 970A-DS3. If it means anything I had it running fine at 1866 with just the two cards using the XMP profile.

Thank you
