XMP leads to screen flickering on displays
XMP leads to screen flickering on displays
I recently purchased the VENGEANCE LPX DDR 2 x 8GB 3200 MHZ RAM and checked my system settings. The BIOS reported a clock speed of 2133MHZ, so I enabled XMP and it increased to 3200 MHZ. After restarting and launching a game or running benchmarks, my monitor began flickering with intermittent connect/disconnect noises and lights. Music played normally, but my three monitors would power on and off. I shut down the PC hard and restarted with XMP enabled. When I searched for a second profile, it wasn’t available, suggesting I didn’t have two profiles set up. After briefly disabling XMP, no issues arose. Once I reactivated it, after about five to six minutes of benchmarking, the flickering resumed and stopped. I turned off XMP for a short period, then restarted it again. In the last 30 minutes, no problems occurred. I also had two 8GB 2666MHz RAM sticks installed, but they caused crashes when running at full speed. I considered replacing them to resolve the freezing and crashes, but my current setup has 2133MHZ 2x8GB RAM. The motherboard I’m using is Z170A with an MSI Z170A PC MATE, powered by a TX650M PSU and an 860 Samsung EVO SSD. Several users discuss similar experiences on forums, including the same RAM model and motherboard details.
But I’ll miss out on 3200 MHZ, which is what I paid for... I’d save around £20 if I paid for 2133 MHz. My 1% low would be better with Ryzen’s higher memory speed. I’m using an i5 6600k at the moment, so it doesn’t affect me much, but I’m planning to switch to Ryzen soon. R5 3600
To determine the difference, check the change in performance after enabling XMP. For manual OCR, it depends on your specific setup and settings.
