By write speeds G.SKILL TridentZ Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 4400

I have an ASUS Maximus X Apex with 8G x 2 4400 DDR4 ram modules.

The memory timings are set up according to XMP settings. I am however running the ram at 4300, since 4400 is not stable.
Ram voltages is set to 1.5V

When running passmark software Performance test 9.0 I am getting good reads but very bad write score:
Read Uncashed 20648 99% percentile
Write 3670 23% percentile.

How do I correct this? It seems odd that the writes are so bad.

Do you have a link to the ram kit? 1.5v is too high. It should be within 1.2-1.35v. Are you on the latest BIOS revision for your board?

Thanks for the feedback.

The standard voltage as recommended is 1.4V. At that voltage it runs at 2000Mhz (4000) To get to 2150Mhz (4300) it requires 1.5V. The rams does not heat up, so I presume it is ok.

Here is a link to the product. It is also endorced by ASUS. https://gskill.com/en/product/f4-4400c19d-16gtzsw

I sorted out the problem. t_wrwr_sg now set to 6 (was 63) and t_wrwr_dg set to 5 (was 63)
