What do You think. Does this MB handle 3200Mhz after OC ?]]> Tue, 09 May 2017 08:33:22 +0000 https://forum.asrock.com/forum_posts.asp?TID=5047&PID=28771&title=fatal1ty-x370-gaming-k4-cant-get-it-stable#28771 <![CDATA[Fatal1ty X370 Gaming K4 can't get it stable : parsec wrote: berner wrote:it's ...]]> https://forum.asrock.com/forum_posts.asp?TID=5047&PID=28616&title=fatal1ty-x370-gaming-k4-cant-get-it-stable#28616 Author: berner

it's possible that the temps are real (my ryzen starts throttling at 85° so maybe yours is at the temp limit?) sadly asrock chose a very strange way of fan management.
It looks at the mainboard CPU temp which is something different from the Tdie.
This temp seems to be a diode on the motherboard, for me it "laggs" behind Tdie and is around 10° C lower.
This leads to the fans not reacting properly.
Maybe you can check at what speeds your fans run. Also you may want to edit the fan curve.(In Bios or f stream)

There are 2 CPU temps reported for my R7 1700.

One is under the CPU tab in HWinfo and i assume this is the correct one. I call this one Tdie.

Then there is a temperature reported under the mainboard tab (so i assume it's reported by the mainboard).

Those 2 Temps are very different from each other, in idle they are similar but under load cpu die is about 10°C higher than the "mainboard cpu temp".

It also takes the "mainboard cpu temp" much longer to react to load difference so i assume it's a temp sensor located on the motherboard (maybe directly under the CPU?)

If you take a look at my fan settings you can see that at 70°C the fan should spin at 80% or 1306 rpm.

It does however spin 1059RPM which is much closer to around the 60°C the "Mainboard CPU temp" reports.

This leads me to the assumption that the mainboard uses this temp to controll the fans. (Otherwise there would be a much bigger problem with fan control)

While i can compensate the offset of about 10°C in my fan settings i can not do the same with the slower reaction time of this temp sensor.

When i tried 1.4V the CPU reached 85°C (Tdie) and begann throttling before the fans could react.

After they reached higher RPM the Temp got lower again.

In conclusion i think it makes no sense to use this "Asrock house made" Mainboard temp to control the fans when we have a perfectly good Tdie directly from the CPU.

I think this is a serious flaw of my motherboard (k4 x370) and maybe other asrock Boards.

If you can, please report this to Asrock since this should be a very easy problem to fix with some lines of code.

This MB looks very good in specification but these problems with memory compatibility are the only block to click "buy now" for me and I suppose for many people either.

We all wish to run our builds in worst scenario in 2933Mhz

So.. we are just need to wait for stable,well prepared bios - hard to tell but let's be Patience : )

I don't understand why they chose a temperature offset for the X series chips either.

I mean, I get that they want your cooling to kick in with enough headroom to be effective before you reach high temps, but all of the 7 series chips are unlocked so why bother just offsetting the X chips and not all of them?]]> Sat, 06 May 2017 19:46:47 +0000 https://forum.asrock.com/forum_posts.asp?TID=5047&PID=28610&title=fatal1ty-x370-gaming-k4-cant-get-it-stable#28610 <![CDATA[Fatal1ty X370 Gaming K4 can't get it stable : Rares wrote:Successsss! 3.9GHz@1.3025v......]]> https://forum.asrock.com/forum_posts.asp?TID=5047&PID=28607&title=fatal1ty-x370-gaming-k4-cant-get-it-stable#28607 Author: parsec

Successsss! 3.9GHz@1.3025v... but the temps are high, HWinfo reports 84 degr. C T(ttcl) in Prime95 (torture test). But I think the temp. is not real... HWinfo has 2 temps: T(tctl) and the "normal" one.

AMD has two temperatures reported from a Ryzen processor, or at least from the Ryzen 7 series.

They are Tdie and Tctl (control), both may be reported in HWiNFO depending upon the Ryzen board, given what I have seen. My X370 Killer SLI/ac shows both.

Tctl has a programmed in offset of 20° C relative to Tdie. So a Tdie of 25° C will be a Tctl of 45° C.

AMD supposedly did this for use with their stock Ryzen CPU coolers, and different Ryzen processors. How that is supposed to work I don't understand.

For the CPU_FAN1 header, ASRock is using the Tdie temperature to control the fan's speed. The mother board temperature is not being used for the CPU_FAN1 header.

The Chassis Fan headers, or some of them depending upon the board and UEFI/BIOS, have the option of selecting the mother board temperature, or CPU temperature to control the fan's speed. The default setting is the mother board temperature, which normally does not change much at all. That is easily changed to monitor the CPU temperature in the HW Monitoring screen.

What do you mean by "mainboard CPU" temperature? Yes, the mother board temperature won't change at all compared to either Tdie or Tctl. If you have your CPU cooler's fan connected to a Chassis fan header, either configure it to monitor the CPU temperature, or connect the fan to the CPU_FAN1 header. Or is your CPU cooler's fan a three pin fan?

No you should not use benches to stress test at all.
Run Prime or occt or even AIDA stresstest (You wanna stress CPU and FPU here, maybe even cache too.)

no i didnt test with prime

i ran all at the same time
aida stress test
and then started passmark
and then started
superpi
and then started cinebench
and then just to add something alse to the mix repeat clicking to keep it running cpuz bench

so five benches/stress tests at once
i can confirm this did actually quite stress out the system with load LOL

the results were as expected very low scores on the benches Shocked

and no naughty lock ups or crashes
after about ten mins (including restarting anything that finished) i got bored felt sorry for the poor old system and decided id never be pushing that many 0's and 1's thru the cpu and ram ever again

do you think i should try maybe 7 or 8 benches at same time Big smile

cpu silicon lottery
power regulation and quaility of the board
and of course the power supply unit

Tested with prime? Try a test with boinc asteroids@home if u don't have a watercooler your system will crash.
And not all ryzen CPUs can run with high clockspeeds]]> Fri, 05 May 2017 20:59:33 +0000 https://forum.asrock.com/forum_posts.asp?TID=5047&PID=28541&title=fatal1ty-x370-gaming-k4-cant-get-it-stable#28541 <![CDATA[Fatal1ty X370 Gaming K4 can't get it stable : Well, probably you're right...]]> https://forum.asrock.com/forum_posts.asp?TID=5047&PID=28535&title=fatal1ty-x370-gaming-k4-cant-get-it-stable#28535 Author: Rares

Well, probably you're right about that, but my guess is that the BIOS is in a early stage and this could lead to errors/wrong hw readings/etc.

BTW: a new AGESA v1.0.0.6 is already in the house :)
