DogEared Posted February 27, 2018 Share Posted February 27, 2018 Hi folks, I'd appreciate any advice on getting this RAM up to speed as it appears to not be running correctly. I benchmarked on UserBenchmark and it suggests the RAM is not configured correctly. http://www.userbenchmark.com/UserRun/7548249 I checked the BIOS and XMP is enabled. I also checked the dimms are in the correct slots (A1, B1, C1, D1) UserBenchmarks: Game 73%, Desk 123%, Work 103% CPU: Intel Core i7-7800X - 108.7% GPU: Nvidia GTX 970 - 65.1% SSD: Samsung 960 Evo NVMe PCIe M.2 250GB - 223.1% SSD: Samsung 850 Pro 256GB - 111.9% SSD: Samsung 840 120GB - 56% RAM: Corsair Vengeance LPX DDR4 3000 C15 4x8GB - 84.6% MBD: Asus TUF X299 MARK 2 Windows 10 64 Link to comment Share on other sites More sharing options...
DogEared Posted February 27, 2018 Author Share Posted February 27, 2018 So as far as I can tell it's running in single channel not dual channel. Link to comment Share on other sites More sharing options...
DogEared Posted February 27, 2018 Author Share Posted February 27, 2018 I tried booting with one DIMM in slot C1 and then two DIMMS in C1 and A1 but there's no difference. Will try ASUS too. Link to comment Share on other sites More sharing options...

DogEared Posted February 28, 2018 Author Share Posted February 28, 2018 I see quad on there. Yeah :biggrin: The advice on the UserBenchmark misled me, it's running in quad so dual channel doesn't appear in CPU-Z. The XMP profile wasn't working right and that's why it was slow - I tweaked it manually in the BIOS so that each channel is running at 1515, so effectively 3030. Thanks for your input.

CoolnessGuy Posted March 3, 2018 Share Posted March 3, 2018 Be careful with that RAM, on the MSI boards it would fry the memory controller if you wake from sleep in windows. Never tried waking on the ASUS board. Link to comment Share on other sites More sharing options...
