Does QFan allow me to add a sensor and then adjust temps based on that? Or are my only options CPU or Mobo. I ask because Im cooling the CPU as well as 2 graphics cards so want to set fan profiles based on water temp (i figure thatd probably be best).

You have a lot of options. If you have an all in one cooler, there is a connection for the AIO cooler(near the CPU fan connector). For water, you have the watercooling "zone" where you can plug in your water flow, and other sensors. I am on an AIO setup myself(I only wish I could spend $500 on a good quality water setup, but my wife might divorce me if she found out about the purchase).

Hmmm, i dont seem to be having any issues with RAM as many are discussing,

i am using the corsair lpx 3200 2x8GB
with the timings and voltages set according to what was written on the sticks, pretty sure 16 18 18 18 36 1.36v
worked first time on 1002 bios


i do get occasional and intermittent errors when using the blended Prime95 runs

Have the 1600x chip

I like firestrike. The combined score, even though it is greatly misunderstood and generally ignored most of the time, is a fantastic gauge of how well a computer will perform in a gaming load and helps in quantifying the performance benefits of the memory overclocking endeavors. 

The reason for this focus on higher speeds for RAM when Ryzen comes into the picture, is because Infinity Fabric runs at half the RAM speed, so the faster your memory speed, the faster your overall performance will be.

As for 3D performance at Gen2.0 I really can't notice that much of a difference have tried some testing at BCLK 100 and I think the ram effects are more beneficial and make up for the drop in PCIe speed.

Funny you say that as the combined test was the achilles of the FX CPU. 3DMark had it coded in such a way that the bench would only use 4 of 8 cores on an 8350. There still seems to be some discrepancy IMO with the new Ryzen architecture.

2x8 is as easy as you can get to hit rated speeds. 2x16 Hynix is NOT easy for many of us to get to 3200, especially if the memory is the "cheap" 16 latency stuff. The newer BIOS versions are making it easier, but going 4x8 for your memory configuration makes it more difficult to get high RAM speeds at the moment. AGESA 1.0.0.5 will hopefully make it as easy for me as your 2x8 configuration was for you.

AHHHH ok, i didnt realize the issue was more towards having >16 gigs or >2 slots populated.... well i guess im glad i didnt go with the 4x8GB as i initially planned

you don't have to. elmor said a few times that disabling the skew on 1700x / 1800x reverts back to amd default behavior. so 1700 non x users are not the only ones who can disable it. anyone can and be fine as... it goes back to amd's default behavior.

Well, I won and lost the silicon lottery at the same time. I have an 1800X that won't do over 3950mhz stable no matter how much voltage you throw at it. Currently I am running it at 1.39v LLC 3, but even with Corsair H100i and thermal grizzly hydronaut paste, it throttles at 70/90C. Well with new 1007 bios I enabled sense skew and my temps dropped, which is ridiculous since I changed nothing with the speed or volts. The chip was throttling when it probably wasnt even the real temperature. This chip/mobo needs to have ONE REAL TEMPERATURE THAT IS ACCURATE. Enought with the b@ll**** of any setting change in the bios changing your temp reading to random numbers. Anyways I also found that I could lower my vcore to 1.36v LLC 3 with bios 1007 so that was good, but still it gets to 73/93C intel burn test and throttles, which it definately should not at those speeds and volts. And yes I have excellent paste and it is seated with thumbscrews max tightened by hand not screwdriver, and tried a few seats. I just have a hot running chip and it doesn't help that no matter what you set in bios you can't get a real temp reading, but 4 different temps in hwinfo, corsair link, asus software, ect.
But the good news is I won the silicon lottery for memory. I have gotten 3600 16-16-16-36 completely stable. The trick was too little or too much soc and dram volts both don't work, you need the exact numbers. For me dram had to be 1.41v and vsoc had to be 1.06v, anything more or less and it wasn't stable. I don't have Aida because I am not paying $37 to get a latency readout once a year, but I had a very old Aida which gave me a latency in the 60s, so pretty pleased, now my rig should beat 7700k in gaming as my infinity fabric is running at 1800mhz and mem at 3600. My cinebench scores are nothing great, just shy of 1700 because my chip won't go over 3950mhz, but I am not going to notice that 50mhz difference (psychologically I wanted 4 ghz and paid up for an 1800X over a 1700, but no luck). I guess I will be really happy if after May I can buy two more of my gskill Tridentz 3600 C16 and run 4x8 for 32gb at 3600, but not holding my breath, lol. The only weird thing is performance test memory benchmark still gives me a crappy score, yet my memory is damn fast with a low latency, not sure why my 6 year old intel system with ddr3 2133 cas 10 kills Ryzen in that benchmark, yeah the latency is way lower on my old rig, but the bandwith is way higher on Ryzen.

Thats for the headers on the motherboard right? Im talking about the software in BIOS. Generally for setting fan curves (at least in MSI BIOS) it gives me the option to set the curve based on the temperature reading from either the CPU or Motherboard. I want to plug in a water temperature sensor into the header on the motherboard, what Im asking is if the fan control software will let me set the fan curve off of that sensors output. This way its adjusting to water temp as I assume thatd be ideal in a full system loop. Custom water btw, not aio.

Thanks, i am using just some 2 pin thermo couples i purchased from FrozenPC

I am not sure why they are not providing any reading at all

If they are actually thermocouples, they work by the difference in electrochemical potential between two different wire compositions. The twisted-together pair of wires develops a voltage. You need a special thermocouple meter to read them. They have the advantage of being very precise, but the inconvenience of not being thermistors where one just reads the resistance with an ohmmeter and infers temperature (assuming one knows which family of thermistors they belong to).
