@AMDMatt Would be interested in seeing your new results from handbrake test:

My results are almost identical.

Temperature Reporting
The primary temperature reporting sensor of the AMD Ryzen™ processor is a sensor called “T Control,” or tCTL for short. The tCTL sensor is derived from the junction (Tj) temperature—the interface point between the die and heatspreader—but it may be offset on certain CPU models so that all models on the AM4 Platform have the same maximum tCTL value. This approach ensures that all AMD Ryzen™ processors have a consistent fan policy.



Specifically, the AMD Ryzen™ 7 1700X and 1800X carry a +20°C offset between the tCTL° (reported) temperature and the actual Tj° temperature. In the short term, users of the AMD Ryzen™ 1700X and 1800X can simply subtract 20°C to determine the true junction temperature of their processor. No arithmetic is required for the Ryzen 7 1700. Long term, we expect temperature monitoring software to better understand our tCTL offsets to report the junction temperature automatically.



The table below serves as an example of how the tCTL sensor can be interpreted in a hypothetical scenario where a Ryzen processor is operating at 38°C.

So what is the real temp of my CPU?

 

[mmj_uk]

20C less than reported for 1700X/1800X, apparently.

I don't really understand why it's been done though? are 1700X/1800X allowed to run 20C hotter?

CPU (Tctl) is reporting 39.8C, my Kraken says liquid Temp is 29.9C, so going by AMD maths the real temp of my CPU should be 19.8C? Thats nuts it. Even though my krakens block is very cold to the touch.

 

[mmj_uk]

What are you using to monitor? it might be that it already has the offset taken into account. I'm trying to figure out why 1700X/1800X need a +20C offset for the fan policy to be consistent, maybe it is due to the different stock fans?

 

[mmj_uk]

It says tCTL is offset so that all models have the same maximum tCTL value so that must mean 1700X/1800X need to run 20C cooler? less heat tolerance due to higher clocks?

Opened the Ryzen system I built on Friday back up to install a F12 on the D15 (second stock fan doesn't fit due to no low profile DDR4 existing), figured somebody somewhere may like to see it /shrug.

Is it possible motherboard manufacturers can work around this, I.E when I flashed my GB gaming 5 from stock BIOS to latest beta BIOS I was sure it dropped CPU temp by ~20c but thought I imagined it lol.

I just installed an XSPC Raystorm block. Temps are amazing now, under a quickie full cpu-z stress it didn't go above 73c at 4.1Ghz with 1.35v.

Thanks for this. I'm thinking of ditching my 360 AiO and getting a D15 for my Ryzen build.

What have you tried to check stability?

I'd that's stable its a good chip

Oh I have no idea if it's stable yet this was a temperature test against the crappy Cooler Master I had installed.

Ah right

Well, hopefully it is right

Dam post this in wrong place

Hey all + @AMDMatt I got c6h and followed your step by step Pstate and following the post on overclock.net. Too much info there so i follow yours from here.
Only thing I'd like a 2nd opinion on is these volts. you think they wrong readings from mobo coz they high across board. Psu is brand new leadex II Gold Thanks

You probably won't need to remove the second 150mm fan, it's worth checking dimensions but I only had to do it because my small case barely has enough clearance for the heat-sink itself and I had to raise the fan due to memory clearance (my X79 system was using low profile DDR3 and nobody is making LP DDR4 yet).

Well made video of first boot. No tests ect full on water loop from start total of 4 hours of draining filling swapping my 5820 to 1700x

Yeah, water can be a pain when swapping.

Mine took a full day basically, but I was also removing a radiator and simplifying things.

Hope I don't regret removing the 420mm...

Looks good, i have fine tuned my settings now so have a few suggestions.

1. Change VDDSoc voltage to offset and put it at +02500. If needs be you can go higher but yours is way too high, try and stay below 1.15v tops. I think i was using 1.175v when i made that post.
2. Set PLL voltage at 1.85v, i found this helps when overclocking the memory at high CPU frequency.
3. CPU Voltage looks okay, but perhaps you can lower it a bit if you are only running at 3.8Ghz. 4Ghz should require around 1.4v or higher. 3.8Ghz should be around 1.3v or lower.

Im on external ALWAYS ez to drain ect. Always tempted to go 1080 NOVA and use it as side pc panel

Had not much time to mess around. Problems booting at 3000mem on 100bclock but works fine @ 112.4. Fast Dirty OC

Vcore set is 1.4 jumps sometimes to 1.417 on llc3. On auto stock settings was jumping pass 1.5 LOL

 

[Ubardog]

What im worried about is I set set things manel boot and/or check bios and it show higher than what i have set.

IE PLL set at 1.8 gives a reading of 1.95
CPU SOC man @1.13 Gives 1.22
Even the 12v 5v n 3.3v are over
This is my concern ...

Why the fk did they put the DMM points under the 24pin hard to measure but i will be trying this in a sec and compare metered results to reported
Is the only way i can stop myself from worrying Before going to 4g oc

 

[LtMatt]

Are you on the latest bios?
