Bios showing memory at 1600 when it should be 1866

[matrnelson]

I am trying to adjust my memory speed to what it was advertised at. When i change it in the bios from 1600 to 1866, i get an error at boot and the speed defaults back to 1600. I played with the timings and was able to boot with memory at 1866, but now i get BSODs that say clock_watchdog_timeout.

Its obvious that im doing something wrong. Any guidance is greatly appreciated.

hope this screen shot helps

OK, you're prob on an Intel system, Haswell? Go into BIOS and enable XMP then select profile 1, then let me know and throw in what CPU and mobo

Thanks for the reply.

I have an AMD system.
AMD FX-8150 3600mhz
Gigabyte 990fx-ud5
Patriot Viper 3 DDR3 2x8GB 1866mhz
Radeon HD 7970

What does it show in the Memory tab?

Look for XMP, DOCP or EOCP, probably in the advanced/tweaker area of the BIOS and enable whichever and select 1866

Thanks again for your help. I went into the bios > EOCP and selected 1866. Memory clock bypassed it and stayed at 1600.

I went back into the BIOS>EOCP and selected Profile 1, then specifically chose 1866. In order to choose 1866, I had to change the cpu frequency from 222 to 200.

After saving, windows failed to load. However, it rebooted fine shortly after. The event log reads two events:
The computer has rebooted from a bugcheck. The bugcheck was: 0x000000c2 (0x0000000000000007, 0x00000000000011c1, 0x0000000000000000, 0xfffffa8010da8ee0). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 071613-18283-01.
and
Windows failed fast startup with error status 0xC0000001.

I should also add that this ram is not on the Gigabyte supported ram list. So compatibility may be an issue.

Compatibility isn't an issue, the QVLs are worthless, see my info thread here:

They only test at 1333 or 1600 whatever the mobo default is....prob need to raise DRAM voltage + 0.05 from spec and try that, may need a little extra to the MC (memory controller) voltage also to stabilize
