Is employing four 4DIMMS units paired with an Intel 285K processor detrimental?

It's quite unusual. I successfully completed two full rounds of Memtest with the HYNIX 8600 CL40 at 1.45V. I stopped it because I didn’t have time. Then I increased to 9000, but it failed to boot. I went back to the same 8600 profile and it also failed. What’s going on? It seems like memory training is affecting the performance. The CMOS was cleared, yet the 8600 profile still doesn’t work. Currently I’m running at [email protected] and passes MEMTEST without issues. Disappointing that it causes errors at the advertised 8000 CL36. It looks like one of those unstable 1.4V profiles exists:
7600 36-48-48-84
7800 38-48-48-84
8200 40-52-52-130
Or...
Using all four sticks with 7200 36-46-46-115 might be better.
The 7800 seems to be the most balanced option.
Unfortunately, Intel 200s automatically selects XMP Profile 1 and hides any other options when boosting. This is the only unstable XMP profile available under 200s boost. Probably GIGABYTE won’t let you choose a different one.
Just use it as a starting point. I'll check more thoroughly within the OS after choosing a suitable profile. Disappointed the 8000@CL36 isn't functioning well; stops me from utilizing Intel 200s boost.
You need to examine the application you are using. When comparing benchmarks and identifying which are impacted by memory usage, the only ones I've noticed where memory speed really matters are those that perform operations like pkzip. It seems that running the IGPU would also benefit from faster memory.
For most applications, the memory capacity has a much greater impact than the processing speed. You're likely using significantly more than the typical 32 or even 64GB tested, making it difficult to determine the exact effect of switching from two sticks to four sticks, even without considering speed differences.
In general, almost all performance will be constrained by the CPU or GPU well before memory becomes a significant factor.
When using two kits, anticipate variations in XMP configurations within each stick.
The information provided might differ. The XMP profile in a kit is intended to optimize performance for that specific setup.
Your motherboard may struggle to interpret these differences.
If you wish to maintain both kits, avoid relying on XMP for configuration.
Manually set all parameters and evaluate your optimal settings through testing.
As before, noticeable performance drops are unlikely without a real-world benchmark.
This design choice exists because multi-stick configurations aren't feasible with standard RAM.
