DorSegal Posted November 19, 2017 Share Posted November 19, 2017 Hi, I have problem with low RAM write speed on AIDA64 benchmark. My platform is: i7-870k@5GHz, Aorus Z370 G7 2x8 GB G. Skill Trident Z RGB 4133 CL19 Ram is in double channel configuration with XMP profile active. Motherboard have newest BIOS This is comperation from 3800mhz memory with the same specs: Quote Link to comment Share on other sites More sharing options...
Fiery Posted November 20, 2017 Share Posted November 20, 2017 Our only guess is that the memory controller (IMC) falls into an unstable state with your 3733 MHz configuration, and that causes the IMC to fall back to a single-channel operation mode. Even though it reports as if both channels were operating properly, the numbers indicate single-channel mode. Another, although quite unlikely guess: there are certain "bumps" in the memory frequency curve where the IMC needs to insert additional wait cycles in order to stabilize itself. That may cause an uneven increase of performance as you increase the memory frequency. But when that happens, the "bumps" aren't that huge as in your particular case.
