Issue with G.Skill TridentZ DDR 4 32Gb 3600 Kit

[Homewrecker]

I'm running the RVIE with an i9 7940X and 32Gb of G.Skill TridentZ RGB DDR4 (4 x 8GB) 288-Pin 3600 (PC4 28800) P/N F4-3600C16Q-32GTZR Memory.

I've updated the Bios to 0802 as well. The board Posts fine and defaults to a 2133Mhz 1.20V memory setting. With everything else left at default settings I change the Ai Overclock Tuner setting to 'XMP'. The memory specs are detected just fine - 3603 at 16-16-16-36, 1.35V.

When I save and restart, the Post hangs with the display code on the board reading "Code AF: Detect Memory". I have to clear the CMOS and it Posts just fine back into the Bios with the original default 2133Mhz 1.20V setting.

I installed all 4 modules as per the instructions in the motherboard manual (DIMM B1, A1, C1, D1 slots). With XMP enabled I manually override the frequency and can't get past 2800Mhz.

The next step up is 2933Mhz. When I try that frequency the board hangs during POST with "Code AF: Detect Memory". I have to clear the CMOS to get it to boot back to default settings.

I then tried each module individually installed in the DIMM C1 slot as per the manual. Each module behaved the same way. I could not get past 2800Mhz and each one made the Motherboard hang during POST if set to 2933Mhz or higher. The same POST code also appears - "Code AF: Detect Memory".

In the past all one would have to do is bump up the DRAM voltage slightly but from everyone that has posted on the ASUS forums they have no issue with this kit running at 1.35V.

I'm tempted to RMA this kit.
Is there another setting in the BIOS I should change to make this kit work or could this be a bad kit?

Note: This Kit is on the ASUS DRAM qualified vendor list as well.

turn on, booted up, press power button once

The board isn't installed in a case. It's being tested on a bench so there's no actual power button.
I guess I could jump the pins on the header for the power switch.

isn't there a start button on the right?

I'm using the start button on the board to power it up but I'm not sure if you can use it to power down as well. The Manual only mentions using the button
to power it up. I'll try that and see what happens.

Should be able to just push it momentarily to power down.

Push and hold it for a sec and the motherboard will shut itself off.

After all these years using Rampage Boards I didn't realize you could also use the start button to power down lol. Got that sorted out. After powering down the BIOS switch does in fact work.

Also got the memory working properly at the rated speed thanks to Shamino's suggestion.
I increased the Uncore Voltage offset to +0.40V and the board now boots with no issues. I'll install Win 10 and run some benchmarks just to make sure everything is stable. Once I get everything put into the case I'll move on to OC'ing.

I'm glad I didn't have to RMA this thing since finding a Ziploc bag full of Bitcoins lying on the sidewalk would be easier than finding another board right now.

Thanks again Shamino.

just based on guessing, set the following





and set uncore voltage offset to 0.001

I tried a few more re-boots and everything works fine after making the suggested changes. However, after installing the Sound Card (SoundblasterX AE-5) it hangs during reboot again with the same "Detect Memory" code. I remove the sound card and the board still hangs with the "Detect Memory" code even though the previous recommended settings are still in place.

I use 'safe boot', I don't change anything and exit the BIOS and it boots fine into windows.

Could this be a PSEU related issue. I'm using a mew Corsair CX650M just for testing (the rig it's going into has a 1500W PSU). I'm not using the 4 pin EATX12V_2 connector since the PSU does not have a cable for it. I am using the 8 pin EATX12V_1 connector.

Should I return this board? I shouldn't need to make so many adjustment just to get the thing to boot properly.

[Homewrecker]

Thanks. Tried it. When I saved and reset I got a code that stated "Check NV Ram". I reset again and it booted fine so far.
How come the lower uncore voltage compared to the previous suggestion?

Should I back-off the CPU AUX2 and Input reset voltages to find the threshold or is it safe to leave there? Does this affect the CPU Temp?

I'll try a few more reboots and install the sound card again. If this keeps happening though would you recommend that I return the board?
