Can anyone tell me if this RAM will be compatible with my system?

Mobo: ASUS A78M-E
CPU: AMD A10-5800K
RAM: HX318C10FK2/16 (1866) RAM Link

I just built this system and I currently have G.Skill F3-2133C9D-8GXL (2133) installed. I have messed with the BIOS and every setting I can think of, but I cannot get the RAM to run at anything besides 1600. I have tried a single stick to check if one stick is bad, but still only can get 1600.

Any help would be appreciated, I can provide more specs if needed.

Thank you

Can you not select 1866 in the BIOS or will your system not run on 1866?

To select 1866 you can simply use the RAM's XMP profile. On AMD boards it something like E.O.C.P. settings, select Profile1 and check if that works. Otherwise try E.O.C.P. -> DDR1866.

I have tried every single D.O.C.P profile above 1600 including 1866 and 2133. The motherboard is speced to run 2133. I have tried both Profile 1, which sets it at 2134 and Profile 2 which sets it at 2133. Both profiles set the timings to the speced 9-11-11-31 at 1.65v

So what happens when you set it to one of those profiles? Does your system boot up, is it unstable, does CPU-Z or a similar program show weird speeds?

It will boot fine at anything below 2400. If I try to boot at 2400 it fails, which makes sense.

Here are links to screen shots of CPU-z readings when the DOCP is set to 2133. Which the BIOS displays Target DRAM: 2133Mhz

It looks fine. You know you always have to multiply the speeds CPU-Z, Speccy etc show by two right?

Wow, now I feel stupid. So why does Task Manager show my RAM as running at 1600Mhz?

Don't feel stupid, almost everyone is confused by it at first. I still don't get why the people who make monitoring software don't just add 'x2' or something behind the RAM frequency.

Where does Task Manager show frequency? Can't find it on my PC. I'm on Windows 7 though, maybe it's different from Windows 8/Vista/XP/whatever version you have.

If you wouldn't mind answering one more question, in your opinion what is better:

16GB at 1866 or 8GB at 2133?

I know either will run the majority of current games perfectly fine, but I work with a program called ArcGIS that uses a shit ton of system memory to load mapping software and pull info from databases. Any suggestion on that?

Yea if you click the Performance tab and then click Memory it tells you the RAM speed. And you are correct, Windows 7 does not show it. However, with this new info you provided me I have googled and it looks like numerous people are running into the same issue with it showing incorrect RAM clock and CPU clock.

UPDATE: Should have stated that im on Windows 8

Thank you very much for taking the time to answer this.

I don't mind at all ;) 

It depends, if that program uses more than ~6GB of RAM, go with 16@1866. Frequency (and timings for that matter) don't make a huge difference in real world situations.
In this case size probably matters more. If you're RAM usage is under say 90% under maximum load with 8GB RAM, you could however use that and gain a tiny bit more performance due to the higher frequencies. You'd also have to consider timings though, 1866MHz CL8 is faster than 2133MHz CL15 for example. This is finicky though and again, it doesn't matter a whole lot.


Glad to hear it's just Task Manager being stupid!
