- I always end up with Q-Code 90 and VGA white led ON.
- Tried 2 different VGA (functioning on other systems), no luck
- Tried another RAM (Kingston 4GB 2133 C14 Hyper FuryX), no luck
- Tried Flashback (all 11 bioses released up now, from 0003 to 1201, with 2 different USB keys), no luck
- Tried multiple Flashback of BIOS1201, 5 times in a row, nothing..
- Tried swapping VGA on the 3 PCI express, no luck
- Tried VGA/HDMI cables, no luck
- Tried loosening the stock Wraith cooler (and also removing it...), no luck
- Tried booting from USB Ubuntu on all USB ports, .. (yes, no luck)
- Reseated various times CPU...
- Tried attaching HDD with Ubuntu to all 8 SATA ports..
- Power supply is Seasonic G series 450W (and no other peripherals connected)
- Motherboard arrived [and then after 1 hour "died"] with BIOS 0902

At this point, I think I can exclude RAM and VGA, and just have to RMA motherboard or CPU.

I have 4 doubts remaining (maybe only @elmor can answer?):

1) Since I swapped the HDD from previous PC, with Athlon II X3, is it possible that, in Ubuntu, the AMD microcode of the previous CPU messed up Ryzen CPU? Is the microcode rewritten to correct one each time I flashback a BIOS?
2) Is it possible that something PCIExpress has been messed up by VGA or on CPU?
3) Is it possible that psensor on ubuntu messed up motherboard when reading sensors?
4) Is it possible to have an explanation from ASUS BIOS guys of qcode 90 + VGA led? Does it refer to VGA, CPU/PCIE management, or RAM? (also to understand what part I have to RMA....)

Thank you in advance for possible answers, (if any)!
Sorry for long post.. and thank you for sharing your experiences, I am learning a lot..

did you find a solution? did you RMA your c6h?

i have the same q-code and vga led out of nowhere.
OC was stable and voltages in the very safe zone. while watching youtube the display went black and after reboot i got the code 90 with vga led.
i tried nearly all of the above steps with no success. one problem is that i have no other video card to test.
now i`m in the dilemma if i should RMA the c6h or test with other components where i have no idea how to get them temporarily.

can you guys tell me if you see your NVME SSD listed in BIOS section Advanced->NVME Information
and SMART counters for it under Advanced->HDD\SSD Smart Information?

Hi guys! Please read my post in the thread I've just started - DRAM overclocking is PCB dependent. Thanks!

I was unable to stabilize 3333 when overclocking the processor more than 3800 MHz +, the noise "CPU VRM" affects the signal quality
In the modified BIOS open the "PCH" menu, there are no more differences. It is necessary to use the last bios, otherwise nothing will turn out
tRRDS и tRRDL these are different values, by default for the slowest chips "ns" will be 3.700 and 6.000 maximum. In the new version, I will protect against too large numbers smile.gif

1) I did not investigate memory behavior during overclocking via "BCLK"
2) "tRFCns" 320.000 can not be, it is either 260 or 350 depending on the chips.
3) high voltage "VTT DDR" helps to deal with errors, but friezes appear in the system

Yeah I ended up mistyping huh? I'll punch in trfc 267with tras being 28 and gear down disabled and see what happens, overall though I can't be too upset by the performance increase with the minimal amount of screwing around so +1 and all that

People and friends, I have to ask you why some times I power on my PC (Asus crosshair vi hero + AMD Ryzen 1800X) and the fans runs at max rpm, windows 10 start and then shutdown the PC...

I'm using 1701 bios.

Thanks in advance.

Conclusion : The calculator is correct when it shows you the tFAW value of 78
It's not the fastest value though ^^

Edit:
Corrected some values and my conclusion

Well ye but You cant put number above 54 tFAW in bios thats what in on about. Or is it 1701 bios bug?? Never had it above 40 before

for example

Intel XMP by default works with 2T command rate. Ryzen profile works with 1T. Difference between 2T and 1T (1.5ns vs 0.938ns max 0.666ns min)

2T/1T = 1.5 / 0.938 = 1.6 and 1.5 / 0.666 = 2.25

Intel XMP tRRDL have 9 ns for 2T and 9 / 1.6 = 5.625ns for 1T Ryzen
for tRRDS 9 / 2.25 = 4 ns

Thanks for Claryfication As I stated not as good with proper data i r trial and error person biggrin.gif
Will have a look just finished free runnig in my Super Saiyan gear. My Ryzen platform finished producing 40gb of footage from last night's rave. Full on stable no crash while mining new BTCZ on Titan 1700x was postproducing 50gb of Footage from last night, so constant load of 440watts from wall for 8 hours.


For Trance lovers.Image that some of US here do more than run IBT CB15 PRime95 Aida and whole galaxy of other benchmarks and stability test. And do test their rigs in Proper use :]

Overheating i assume thermal shotdown. Check contact of CPU and cooler

Why this happens only some times?

I bet its that ******* temperature offset. Id say disable senceMI in bios and maybe that helps.
