steven467 :
So I've been running my 5820k 4.5ghz 1.28v with 16gb 2133 and it's rock solid with no memtest errors. I bought some corsair 4x8gb 3200 ram to take advantage of quad channel and the speed bump. With xmp enabled I get tons of errors, but at 2133 it passes no problem. I sent that kit back and today received a new kit to have the same issue still. Do I need to overclock anything else for this ram to run at advertised speeds? The only settings changed in bios are the OC, CPU voltage to 1.28v and xmp profile set which sets ram to 3200 and 1.36v. Any insight is appreciated. Thanks!
Hi Steven
It is the strength of the IMC (Integrated Memory Controller) built into your chip that will determine the chips ability to support the DIMMs you are using.
32GB at 3200MHz DDR4 memory is a lot to ask of your IMC and Bios intervention for Primary Timings and Voltage would be required. Your XMP profile may not work as 3200MHz is considered an OC by JDEC memory standards.
I would check the exact P/N of your DIMMs against the MB QVL list to see if they have been tested.
They may or may not work together and you may require a Bios update. Try different Primary Timings and frequencies (You should not have to go above the DIMMs rated voltage) and if unsuccessful then return the kit and get a kit that have been tested in conjunction with the MB QVL.
