Sometimes we get revisions between AGESA releases though.... rolleyes.gif

Why oh why oh why will my fans not calibrate in fanxpert?? I even downclocked to 3.4 in case the OC was affecting it somehow.....

It just doesn't detect them properly.....i never get zero/low rpm in any of the settings - they go full speed - i'm getting

1450,515,712,960,1027... instead of something like-

0,0,515,712,960,1027....

and I can't set them manually - been trying to get them going properly for hours now frown.gif

Not sure if everyone has noticed this but here it is. On this motherboard the voltages are being tagged like this.

VDDCR CPU goes yellow at 1.575v, then violet at 1.64375v.

VDDCR SOC goes yellow at 1.3v then violet at 1.4v

DRAM yellow at 1.35 then violet at 1.40

Why would ASUS not flag core and SOC voltage yellow or violet at a much lower voltages? Perhaps because they don't need to? is it possible the Ryzen can handle these voltages with proper cooling?

I know when I was trying to get my 40.25X overclock stable enough to run a Corona rendering benchmark I pushed core up to 1.575v with 130% over current. SOC voltages were not terribly high because it was not needed, my memory was staying at 3200, but if I was going to push memory higher on say a hero mobo you would probably need to push SOC much higher to get a stable memory overclock of say 3600.

Sure I can run a 41X overclock with 1.475v on the core and surf the net and play some games, get a CPU-Z 4.1ghz benchmark. System seems fairly stable but frankly it's not. Many benchmarks and stability tests will kill it. 4ghz is a brick wall for Ryzen and stability, it takes significant core voltage and current to get stability above 4ghz.

To prove this look at these benchmark results for Corona. My top result is #13 - omgEvenMoreVoltage If Ryzen overclocks were stable over 4ghz you would be seeing a lot more results in the 2.03 or 2.04 sec or less range. I am not sure why my result on the web page came in at 2:04 when my result was actually 2:03

I am no overclocking junkie, not really been into it since the old Athlon back in the 90s. But I learned one thing about silicon when I was in the Army (1980s). I worked in a lab with all kinds of electronic goodies, signal generators, scopes, logic analyzers, freq counters, you name it we had it in the lab. We had a civilian contractor (ex military) who we called the Ancient one. One day he came up to me and asked if I wanted to see how to cook a 8088 cpu. Of course 20 year old me wanted to see a cpu cooked.

First off we observed the cpu in normal operation analyzing the transitions. When you look at the transition they are not a smooth up or down like you might think they are, neither is the +5v or the 0v, they are very jagged sometimes weird shaped. He applied higher voltage and let the cpu heat up and extreme exercise for like 30 min. Reduce voltage and let the cpu run for a few hours at low workload. Power cycle it back up and look at the transitions again, they were noticeably smoother. He referred to the cooking process has boring the silicon pathways. Over a period of a couple weeks we would go back to this cpu and cook it with higher and higher voltage. The final result was logic transitions that were incredibly smooth and sharp when compared side by side with a new 8088. If memory served me right that "cooked" cpu with standard clock of 5-10mhz was overclocking to nearly 30mhz drawing nearly 2x the voltage and 1.6x the current. i am hoping memory is serving me well here.

Conditioning the silicon pathways. The interesting thing is it takes a lot of voltage to condition but once conditioned it takes much less voltage to achieve the same overclock.

Now obviously there is risk involved, some pathways can be weak and too much voltage can blast a hole and short it out. But taking the time to properly condition your CPU can save you grief in the long run. Probably the worse thing you can do to your CPU is go balls to the wall right out of the box. Obviously if you don't want to risk frying your CPU, don't go extreme.

Just my thoughts. Enjoy the Ryzen!

I know bios 0604 has fan issues, something triggers them to go full bore and you can't stop them. One of the reasons I went back to 0515. I suggest loading bios defaults and restarting, should fix it.

Al least with PWN fans (4 pin) no issues here with fan control in bios 0604

There is some certain overclocking condition that triggers it. Not sure what it is but it happened to me and I have read about it happening to others.

Thats weird. My OC is:

Offset +.106 mV and LLC4 = 1.30 mV in bios and 1.35-1.36 mV in Windows.
3.9 GHz

RAM at 2400 Mhz and 14-14-14-34t 1.275 mV
SOC 1.1 mV and LLC1

No problems so far with fans (i use the 2 headers already) They work exactly as configured in bios.

Thanks to the posters in this forum, I am running ARMA III Maxed Out with no less then 60 FPS 1080p. That may not be much for some of you, but I am as happy as can be. Check out my specs. If you play ARMA III you know how hard it can be on rigs. Newest bios, got my RAM up to 2933, using DRAM Voltage = 1.35, and timings at 14, 14, 14, 14, 32. Ryzen 1800x OC'ed to 4.0, with CPU Voltage manually set to 1.40, and the CPU Core ratio set to 40. I am running on air. No heat issues. Just got off of ARMA III, after a few hours of gaming. The settings I mention hear are the only changes that I made. Thanks again!

Sorry I am new. I thought my signature with my specs would be part of the post.
