The RAM frequency overclocking feature is not functioning.
The RAM frequency overclocking feature is not functioning.
My RAM and motherboard both support overclocking, but I attempted to boost my RAM to 1866 MHz from 1600 MHz yesterday. My PC would blue screen for 20-30 minutes after startup or during stress tests in Prime95. I tried gradually increasing the voltage, but it didn’t resolve the issue. It was running at 1.5v stock speed, and even raising it to 1.6v and 1.65v didn’t fix the problem. The latency remains consistently high at 9-9-9-24.
There is no assurance you can boost your RAM speed past its maximum frequency, but using an XMP profile in BIOS that supports it might achieve results. It's unlikely you'd hit 2133MHz with a 1600MHz chip regardless of timing settings. Adjusting primary timings and switching the command rate from 1t to 2t could be beneficial.
AMD doesn't back XMP support, except possibly for Ryzen models. I've tested a 1600MHz 1.5V CL9 at 2133MHz 1.65V CL11. As discussed, tighter clock speeds are necessary. The motherboards I've used (Intel) offered auto-timing, which allowed achieving the 2133MHz on a 1600CL9 module.
There is no assurance you can boost your RAM beyond its specified speed, but using XMP in BIOS that supports it might achieve results. It's unlikely you'd hit 2133MHz with a 1600MHz chip regardless of timing adjustments. Adjusting primary timings and switching command rate to 2t could be helpful.
