g.skill flare x ddr4 memory

UPS finally surfaced with the G.Skill Flare X memory. Now with 32GB of memory the machine performance should be somewhat better. NewEgg only had this memory in 2 packs, no 4 packs for Flare X were seen.

Most low cost RAM is sold individually while some is sold in pairs. Ideally 4 identical sticks allow for maximum performance.

With 4 identical memory sticks at least the BIOS can more easily fine tune the system. A new BIOS is expected to deal with the existing known issues.

The JEDEC Standard speeds:

DDR4-1600 (PC4-12800) yes
DDR4-1866 (PC4-14900) yes
DDR4-2133 (PC4-17000) yes
DDR4-2400 (PC4-19200) no
DDR4-2666 (PC4-21333) no
DDR4-2933 (PC4-23466) no
DDR4-3200 (PC4-25600) no

The BIOS was able to POST the RAM properly at DDR4-1866. Then when A-XMP was enabled and rebooted the rated RAM speed was achieved.

I had to overvolt the memory like I did with the old RAM in order to achieve the reated speeds. This suggests the BIOS is still not able to properly configure most memory properly.

While the G.Skill RAM is rated at DDR4-3200, the R5 2400G can only achieve DDR4-2933. A Ryzen 3000 series or higher is needed to achieve the maximum speed of the RAM. Older AMD literature showed slower speeds but this may have been due to the lack of availability of all the JEDEC speeds available. Speeds varied with 2 or 4 sticks.

The BIOS startup time is around 18 seconds which is better than the old memory which was 19.5 seconds. This is incremental as much as the slight capacity increase.

No improvement in the device manager or with AMD drivers which still cause the machine to freeze.

Windows bugs are another problem as are AMD drivers. Curious that there no problems with the EVGA GTX 1060 card. nVidia drivers install fine.
