Asus Maximus XI Hero and G.Skill F4-3600C16Q-32GTZKK problem

Hi,

I've bought new G.Skill Trident Z, DDR4, 32 GB (4x8GB),3600MHz, CL16 (F4-3600C16Q-32GTZKK) and I try to run it with i9-9900K on Asus Maximus XI Hero. This RAM isn't on ASUS QVL but it is on G.Skill QVL.

The i9-9900k is not overclocked (standard Turbo mode active) and XMP I profile is set (3600 MHz, CL16-16-16-36 2T @1.35V). Other BIOS things are set of Auto. I've successfuly passed these tests:
- 8 hrs of ROG RealBench v2.43
- Karhu RAM test 1.1.0.0 - coverage of 12600%.

But, I have a problem. When decompressing 13GB RAR file (Winrar 64bit, 7z, etc.) I got errors stating archive is corrupted (archive consistency confirmed on other computer). Strange thing is the problem is when RAR file is on HDD. If I copy this file to SDD and try to decompress it from SDD everything goes ok. I've tried WinRAR decompressing on brand new HDD -> WinRAR failed (there isn't HDD issue therefore).

So, I've done some additional tests:
- only 2 sticks in A2 and B2 slots (16GB @xmp I) - WinRAR passed
- only another 2 sticks in A1 and B1 slots (16GB @xmp I) - WinRAR passed
- 4 sticks (32GB but @3200 MHz) - WinRAR passed.
- 4 sicks >3200 MHz - WinRAR failed.

I've tried to raise DRAM voltage to 1.4V, but WinRAR failed on HDD.

PS. Generaly small RAR files (ca. 2-3GB) are decompressed normally.

May I asked more experienced ROG users to guide me to achive XMP 3600 MHz. Or maybe I should RMA this RAM.
Please help.

@Phillyflyer
May I have few questions concerning your set from your footer?

1. When OC why did you choose higher idle CPU voltage and LLC of 6 instead of lower CPU voltage and higher value of LLC (for example 1.3V and LLC 7-8)?
2. What CPU temps you have @5.2GHz with your voltage?
3. What PRIME 95 (nonAVX/AVX) you used for stability testing? Did you tried Real Bench (I'm interesting in temps you've got)? @5GHz with RealBench I'm hitting 100C on Noctua NH-D15S with 2 fans.
4. What settings you have for RAM OC?

Hi,

On 0602 I am able to be rock solid @3900 MHz, CL 17-18-18-38, VCCIO 1.2V, System Agent 1.2V with my F4-3600C16Q-32GTZKK.
Unfortunately I'm not able to do 4000MHz. I've tried DRAM voltage 1.4, VCCIO 1.4V, System Agent 1.4V, and also tried to relax timings, but RAM test and WinRAR failed 😞
Did I achieve a limit for my F4-3600C16Q-32GTZKK or can I dial something more to achieve stable 4000MHz.

Is someone able to help me to get the same on 0903?
Is any possibility to provide feedback to ASUS BIOS developers? According to forums for many persons 0602 is only way to go.

If looking to push past the memory vendors validated frequency, with limited experience it's best to work up gradually. Try 3700, and so on. I would also recommend sticking with the UEFI that works best with the memory kit in hand.

Whilst doing so try to keep in mind that:

1) Maximum obtainable frequency is a condition of both the CPU and memory capability.

2) VCCSA and VCCIO are CPU and memory dependent and need to be tuned manually. These signal rails need to be aligned, and often too much voltage can hurt stability just as much as too little.

3) Relaxing sub timings as well as primary may also be needed.

Thx for your answer. As I've mentioned earlier on 0903 I can't be stable @3600MHz (vendor verified freq). So I have to stay with 0602 and wait till any new BIOS will provide stability for me.

So, new F4-3866C18Q-32GTZR has arrived 🙂

The first remark - it is for sure not plug and play...
On 0602 I was not able to set XMP profile, I had to set DRAM params manually.
On 0903 I've set XMP profile but I had to set Mode 2 and VCCIO=1.25V, System Agent=1.25V. 0903 looks promising, but I have to do more tests.

PS. Do you know how to turn off thise beautiful RGB RAM lighting? 🙂 When I set AURA to off or stealh in BIOS nothing happens with my RAM lights... still shining 🙂

PS.2 This memory is a killer 🙂

I am not sure you can turn off ram lighting looking at lighting program Aura by asus it has a off but it does not turn it off when I hit apply , in fact it turns nothing off all my stuff stayed the same lol. This is one of the few asus program I still allow on my pc and it only half works lol. Gskill does have its own program but I have no idea what its like...

The G.Skill program is basically Aura, at least in my experience. I've had issues with my 4266mhz CL19 in the past, and so far, the machine is only stable with 0602, anything newer is either memory or CPU unstable. I ended up settling with 3900mhz CL 16.

At this point of time I have given up all other Bios and will stay on 0602 as it was just a huge pain to get my ram set correct on 4266 xmp on every bios was a huge fail.
