Gskill Ripjaws X 2133mhz unable to get rated XMP speeds.

Short Story:

I bought this DDR3 kit:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820231571

Eventhough my MoBo (MSI Z77A-G45) is listed as compatible in manufacturer's website and memory has two XMP profiles, whenever i load any of them my PC keeps rebooting after saving settings in bios.

The best settings i've gotten so far are 9-10-9-28 2T 1866mhz @1.5V.

My CPU is a 3570k overclocked to 4.2Ghz.

The RAM timings are 9-11-11 ... that means they are not rated to run at faster settings (9-10-9) you have chosen. Higher numbers are slower, lower numbers are faster. Go back to rated settings and check:

1. So you took old RAM out and put this in or is old stuff still there ?

2. Have you used the BIOS selection to move all BIOS settings to default ?

3. Reset CMOS if Item 2 failed.

4. Have correct voltage as per package ? Tries increasing DRAM voltage ?

5. Tried both XMP settings

Yeap these timings are 9-11-11 for 2133mhz. You can tight them for 1866,1600,1333 speeds.

I did remove old ram kit and cleared CMOS.

Tried increasing voltage to 1.65v and got the same result.

PC restarts with both XMP settings.

Post pictures of BIOS and I can see if everything is good, mainly CPU and memory settings.

Do you have the latest BIOS?

I'll try to post pictures as soon as i get home from work.

There's a weird thing behind this because pc will boot at 1333mhz 1600mhz 1866mhz 2000mhz 2200mhz and 2400mhz. It just keeps rebooting when selecting 2133mhz.

Is that true while using same timings as the working 2400?

PC boots at 1866, 2000, 2200 and 2400 speeds.

Will keep rebooting when i select 2133mhz, it doesnt matter timing settings.
