SajinTry the aida64 memory benchmark.
SajinOnly other one I know would be maxxmem2.
SajinOh, and I almost forgot about winsat... https://www.ghacks.net/2017/10/16/the-windows-winsat-command/
chinobino.Can you post some screenshots of your memory timings using ASRock Timing Configurator in single, dual and quad channel?
chinobino. It sounds like there is incorrect auto configuration when more DIMMs are added, which could be from poor RAM training or maybe BIOS is not well 'tuned' for 32GB DIMMs.
chinobino.Also, if you have some 8GB or 16GB DIMMs, maybe take some screenshots with those installed for comparison and post them here too.
chinobino.It would be ideal to compare a 16GB x 4 DDR4-3000 CL15 kit with what you have but I don't expect you to buy it just for troubleshooting. I was just thinking of ways to see the change in performance with different capacity DIMMs and thought you may have had access to another RAM kit.
chinobino.When troubleshooting you always want to minimize the number of variables that could be potentially causing a problem.
chinobino.Ok, so that's interesting - did you try running as administrator?
chinobino.Can you please try using Asus MemTweakit 2.02.44 to see if you get the same? Failing that you may have to take screenshots in the BIOS using F12 and a USB stick.
chinobino.The motherboard/IMC seems to be having a hard time with those high density 32GB modules as the passmark scores show.
chinobino.Do you get the same negative performance with more DIMMs added when using lower frequencies? i.e. 2133, 2400, 2666
chinobino.It would be helpful to to know what timings the motherboard is setting.
bob16314While an i9-10900X supports up to 256GB of DDR4 and BIOS 1.19 (and newer) adds support for 32GB memory modules, an X299 Dark only officially supports up to 64GB of DDR4.So, while it might work, I would not be surprised in the least bit that running more RAM than is officially supported by the mobo (or BIOS update to support more, which none do) has some kind of negative impact on something.
bob16314EVGA X299 DarkSystem Memory support: • Supports Quad-Channel DDR4 up to 4000MHz+ Skylake-X (OC), and 4133MHz+ Kaby Lake-X (OC). • Supports up to 64GB of DDR4 memory.BIOS 1.19 Update: • Support next-gen processors• New OC Robot (Turbo 3.0) - adds PerCore mode, and allows to set target temperature• Add PerCore voltage control for Vcore• Add AVX2 for built-in stress test• Support 32GB memory modules• Unlock TjMax setting range from 105 to 110Just sayin'.
bob16314It's all 'in-your-face' if you read your mobo manual and the BIOS update notes. The board officially supports up to 64GB of DDR4 memory and BIOS 1.19 added support for 32GB sticks..Not hard to understand. So I'll say it again, while it might work, I would not be surprised in the least bit that running more RAM than is officially supported by the mobo (or BIOS update to support more, which none do) has some kind of negative impact on something. That is all..Carry on.
ty_ger07Good luck. If you don't want to accept the evidence which is already available, remember to be patient.
