Clock speed issues.

[Tom Cowell]

My 1866 MHz RAM is only running at 1333 MHz. I have adjusted the BIOS like so:

Still no success.

Any suggestions?

My CPU-Z says this:

And this:

So I'm kinda lost now 🙁

what are your full specs? your mobo appears to be MSI 970A-G45. also on top left corner there is a cpu temp of 71c. that is very high temp for your cpu even if was under load!at such temp your cpu would throttle.!that sertainly would affect memory also. have you tried running at 1600mhz?

In BIOS CPU is under full load by default. I had had BIOS open for some time, and have reduced the OC now anyway.
Specs:
MSI 970A-G45
AMD FX6300 @ 3.8GHz
MSI AMD Radeon HD 7850 1Gb
2x4Gb DDR3 Corsair Vengeance @1866MHz

i wouldnt try any o/c with your mobo, or stock cooler. return everything at stock sttings. you have to deal with your temp issue. you must keep temps as much as 60c. not more. if you still wont be able to run 1866mhz better stick with 1600mhz and tighten timings.it will will give you near 1866mhz performance!

Solved it myself, thanks anyway. Just had to change the DRAM voltage from auto to the suggested 1.5V. I also did as you suggested, reverted the overclock back to the original 3.5GHz with the voltage set to 'auto', still hit 69 degrees in BIOS. Bear in mind during BIOS CPUs are under full load ("Because back in the days that DOS and BIOSes were first written, overheating was not really a problem, so there was no need to idle the CPU." - source: http://superuser.com/questions/446735/cpu-temp-very-hot-in-bios-but-okay-in-realtemp-speedfan). Either that's the case, and the stock cooler just isn't enough under full load, or it's showing the thermal margin as opposed to the temperature, which I highly doubt. Still, thanks for the advice.

you are welcome! stock cooler are lame. however if you can pull good temps in windows i guess you are good to go. also run http://www.memtest.org/ and even increasing dram voltage a bit +0.05v can improve stability especially under o/c
