Hi there. If this isn't the right place to be posting something like this I completely understand. Apologies! My memory is posting terrible speeds from the Aida64 Cache & Memory benchmark which has sent me on a wild goose hunt! I then checked CPU Queen and that test seemed correct.
I then checked CPU Photoworxx and that gave me results near the bottom of the list at 1200 MPixel/s when I should be getting around 26000+ MPixel/s. I'm using Corsair Vengeance LPX 32GB (4 x 8GB) DDR4 DRAM 2400MHz (PC4-19200) C14 (CMK32GX4M4A2400C14)) Quad channel configured in A1 B1 C1 D1. I have done a BIOS flash to the latest version (2101). I was using 1901 before. On both BIOS versions I have tried default factory RAM setup (2133) in BIOS as well as the auto & manually configuring XMP 2400 profile @ 14, 16, 16, 31 2T @ 1.200v that it was sold and packaged as. I've tried removing all overclocks and reverting to the original "Optimised defaults" in BIOS. My FPS in games has been about 50% of what it should be. Initially I thought it was GPU but I noticed in Firestrike my CPU Physics test was very poor and so then I thought it was CPU. But now that I've seen this stuff going on with the RAM it looks like it could be the culprit? Any help would be greatly appreciated!!! I've attached CPUID MSR dump to this post too. AIDA64 Memory benchmark result >> . CPU-Z screenshots of Memory & SPD tabs can be seen here >> I then wondered if memtest86+ would see anything but it ran for 10hrs. 11/11 tests completed with 0 errors. You can see the memory is top left is going at 1924 mb/s without overclocks.
