Top Speed for 4x16GB Sticks?

P-h-a-s-e
Level 7
Hi everyone,

After quite a few years I just upgraded my daily driver.

Somehow I manged to get a 10900K and a ROG STRIX Z490-E Gaming. I got it running at 5.2 GHz all cores, 5.0 GHz for mem cache, and a 6741 CineBench 20 score with mid-80's temps (up 8% from stock -- 6234 to 6741). Lots of software loaded so if you have a clean install you may get better results.

When I first started I had only 2 sticks of G.SKILL TridentZ RGB 4000 MHz for a 32GB total. The XMP2 profile improvement was modest (1.3%) but it did get the memory to run at 4000.

Then I realized that I was going to need more memory (Ubuntu VM + Database). So I got 2 sticks more of the same memory.

I started totally green. I knew next to nothing on current tech. But I've since learned that you can't get 4 sticks to run at 4000, that stuff goes on between the mobo, cpu and memory, and with current tech it pretty much does not happen.

Still I managed to get the 4 sticks to run at 3400 and 14-14-30. The biggest boost regarding the memory came from bumping the cache to 48, now running at 50.

Questions:
1) Any hope that ASUS will come up with XMP profiles for 4 sticks (perhaps running this kit at 3600 or 3800)?
2) How far have people here been able to run 4 sticks of RAM? I tried 3600 at 16-16-36, bumping the memory voltage to 1.4V or 1.41 and bumping VCCIO and VCCSA a bit with no luck -- I lost those post-its LOL.

These are my current settings:

AI Overclock Tuner: Manual
ASUS Multicore Enhancement: Enabled
AUX Instruction Core Ratio Negative Offset: 0
CPU Core Ratio Synch: All Cores
All-Core Ratio Limit: 52
BCLK Aware Adaptative Voltage: Disabled
CPU Core/Cash Voltage: Manual Mode
CPU Core Voltage Override: 1.35
DRAM Frequency: 3400
DRAM Voltage: 1.39375
Min. CPU Cache Ratio: 50
Max. CPU Cache Ratio: 50
CPU Core/Cache Current Limit Max.: 255.75
Long Duration Package Powe Limit: 4095
Short Duration Package Powe Limit: 4095
CPU Load Line Calibration: Level 7
DRAM CAS# Latency: 14
DRAM RAS# to CAS# Delay: 14
DRAM RAS# ACT Time: 30


Temps reach low 80's at 100% load (across all 20 threads), but that is rare because usually only 1-2 or perhaps 4 threads hit 100% at a time.

Thoughts on how to push the memory a bit further for a daily driver?

Thanks!
