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

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.
