8320 Black Edition will recognize 1866 as 1600, but will not team it.  It is in an ECS A990 FXM-A v1.1 which will hold up to 128GB teaming memory.  The most it will recognize and team is 1333.  Does anyone know a way to get around this issue?

Manually set it?

The CPU does NOT recognise and set the RAM frequency, the BIOS does. The default frequency is programmed into the RAM SPD for boot up and it's often 1333 MHz. to be more compatible with most PC systems. A smart BIOS will read the CPU model to be an FX-8320 and know to set the RAM to 1866 MHz. if the RAM is capable of running at this frequency without issues.

If the RAM won't automatically run at this frequency without issues or you have a dumb BIOS, then you will need to manually try setting the RAM to 1866 MHz and also set the proper RAM timings for it to run properly at 1866 Mhz. if the RAM is actually rated to run at 1866 MHz. or higher.



-------------------------

Building a reliable PC involves more than just assembling the parts. You need to be able to configure all of the BIOS settings appropriately. This can be quite involved and frustrating as it can require a lot of trial and error with stress testing. It is however often the only means to get a 100% reliable PC.

I have not used ECS so I will assume it resembles my box and e1 else with a rival 990FX rig.

My CPU gets DDR3-1600 from my RAM by default. Which is the top speed for JEDEC.

Now the FX-8350 should support DDR3-1866 but this assume the BIOS can read the XMS profile on the RAM properly

XMS is a bandaid as JEDEC speeds have been outstripped badly while world+dog wait for DDR4 to surface.

Its so bad now DDR4 will now have to enter at at least DDR4-2133 or more to be remotely competitive.

Better cpu and graphic card(s) than faster RAM will do more for your build.  Get a good SSD, too.

DDR4 and higher than 1600 MHz. DDR3 offer no tangible system performance gain for discrete desktop CPUs or even servers at this point in time as countless tests prove that DDR3 running at 1600 MHz. with real applications is NOT a system bottleneck. RAM frequencies up to ~2133 MHz. help the graphic section of APUs a bit but higher than ~2133 MHz. is insignificant.

Good point but, would say that even less RAM speed will suffice nicely with present day components.
