Any ideas?

R5 1600
F4-3600C17-8GTZR (Samsung B)

Thanks for any input, cant get my head round why it will boot at faster speeds and not lower.

DOCP uses BCLK OC to reach 3600!!

Yeah I get that. It uses the 2933 strap and the BCLK. Thing is I used DOCP5 then dropped the BCLK to 109.2 to get 3200 and thats still a no go

Hi, I'm also running a similar setup. Using the water temp for controlling the D5 pump and the fans is working like a charm.
On tip for connecting the temp sensor. When you like to see the water temp in 3rd party sw like Aida64 then connect the temp sensor to the temp header temp1 on the C6H.

The two temp headers of the watercooling section on the C6H are not always displayed in 3rd party sw.
I care more about my fans, since i keep the pump either at full speed or ~28% for silent mode.

No matter which sensor I select it's ignoring the sensor, and sets speed related to CPU temp.

That would actually suck, if i can't make it ignore the CPU temp and just go by water temp... :/
Sadly Speedfan doesn't work yet and probably won't in the near future.

@elmor
Is there really no chance to fully override fan control away from "CPU temp" (which is only an approximation) to just another temp sensor? :/

And you are sure using same vsoc and dram voltage as on 3600?

Not all BCLK values are always working for everybody. So you need to try different values and variations with your multiplier to get around 3200mhz.

Looking at your temperatures I assume you are running 3.8/3.9mhz ?

The discussion about shutting off at a certain temperature was somewhere in begin of this thread. Started by "Timur". I did had the same idea but nobody confirmed this and the discussion went over. You are the first one after a long time suggesting the same again. But before going in to that discussion be sure about the first thing I said. Give it a try at a lower speed with high voltage, to be sure not undervolting the CPU and then see if you can pass the 75c.

cheers yeah ill try that and see what i can come up with, im at 3.9 with 1.312v under load 100% stable but its just all over the place after that regardless of voltage

Hi,

Post your 3600 results in the link in my sig thumb.gif

DRAM I set @ 1.35 but the box next to where you set the value always shows 1.373
SoC was at auto and Im pretty sure I see it hit 1.25ish so I lowered it to 1.1 and it still booted up fine @ 3600.

With the multiplier I'm guessing theres another one for DRAM separate from the CPU multiplier?

someone was saying that there is a auto shut off if the temps exceed 75 deg is there anyway to shut that off? i fell that my temps are lower than what im actually reading and its cutting out well before i even get the 75, i found a setting a ai suit but it didnt make any difference at all so not sure if it took effect or not


When I am trying a higher overclock than 4ghz, I need to push my voltage towards and over 1.5v.
My temps (Tdie) will go over 75. and this is when the cpu starts throttling lower speeds when running prime.
I don't know how to make the cpu believe that he's not overheating yet to the point that he has to throttle.
I am on water, I got plenty of headroom, my pump is running on 7v instead of 12v when attempting this.. I could switch it to go on 12v but its no use of the cpu is in fact lying to itself.

I too wish to know how to get the TRUE temperature of it.

What I thought was that Tdie was the somewhat true temp, with SensMi skew disabled in the BIOS. (if its not disabled, changing pll voltage will change Tdie temp offset as well).
But this causes this early throttling, as Tctl is Tdie+20... the throttling happens when Tctl is 95c.

So I dunno.. I really want to know as well

So for my peace of mind, Running the stress test my CPU is getting up to 80c but this is the +20 offset? As I have a 480mm and 2 x 240mm in my loop (with 980Ti OC as well)

With SenseMi skew disabled in the BIOS, Tdie will be the temp of your cpu, and Tctl will be at the +20 offset.
