1800X - Temperature

[BlaaaBlaaaBlaaa]

Hi guys,

I am new to your forum so please excuse me if am doing something wrong.

My setup looks like this:

Gigabyte GA-AX370 GamingK7
AMD Ryzen 1800X @ stock
F4-3200C14D-16GTZR, Trident Z RGB
Corsair H110i GT
RM850i

I am currently running on stock but I would like to overclock my CPU to 3,9/4.0 if possible.
Bevore starting this I just did a little stress test on stock with Prime95 (Small FFTs) and noticed that the CPU goes up to 75° and the CPU starts throttling.

Is this normal? I thought my cooler should be able to handle the CPU without any problems. Does overclocking make any sense if I am already facing issues on stock?
Anything else I should test?

By the way:
Is there any good guide that covers overclocking with the K7 + 1800X? (Best bios settings etc.)

Thanks a lot and have a great weekend!

Normal...... generally, no. For an 1800X, unfortunately, yes.

How are you determining it's throttling, out of curiosity? Which program etc?

OCing makes zero sense if you're having temp issues at stock speeds - unless you can OC without increasing voltage (+voltage = +heat)

Your cooler *should* be able to handle it, no problem - it may relate to how the 1700X and 1800X are reporting temps:

Supposedly you can subtract 20'C to understand your actual Tj temp - but I have no first-hand experience to confirm if that truly is the case.

Prime 95 may be doing the same as it would with Intel CPU's. I suggest using Prime 95 version 26.6 and retest. If you get the same results then you may need to check your thermal paste and reapply.

@Barty1884:
HWInfo64
It shows the temps without the 20°offset and clock speed in realtime as well as the minimum.

@elbert:
Will do! Which test should I run?
Just did the Small FFTs again - temps went straight to 75° and Clock down to 3.350 Mhz

 

[Seanie280672]

Try AIDA64 Extreme beta instead, I know it will be the trial, but the 20oC offset was sorted out in the beta version: https://www.aida64.com/downloads/NjdhNTg2NzY=

@Seanie280672:

Just tested it again. Temperature goes up to ~72° (same as in HWInfo64). It stays at ~72° but is already throttling to ~ 3450 MHz. Is SMall FFTs the right test to run? With Blend it stays at 72° with stable 3700 Mhz

I dont really bother with Small or Large, but blend is a mix of both.

you may want to go into the bios and disable some CPU feature like AMD Cool & Quiet and C6 States, that maybe the cause, cool and quiet trying to do exactly that.

Like this? Is C6 State - Global C-state Control and should I disable it?
Anything else?

Should I change one of these?
CPU Vcore Loadline Calibration / VAXG Loadline Calibration

Just did some tests again:
With small it still goes up to 75° and throttles down.
In Blend test it goes to 65° and sits stable at 3699 MHz.

So I should just ignore small and can look into some overclocking?

you need to get those temps down a bit before you start overclocking, its got to be your cooling, have you tried remounting the block, re-applying thermal paste, just a tiny blob in the middle of the CPU and then I spread it all over the top of the cpu with my finger with a glove on or similar.

Thanks for your help so far!
Like suggested I removed the cooling paste completly and applied new one:

Before:

After:

After removing the cooler again:

After adding some more:

Should be fine this way - correct?
Just checked again with Prime95 and still the same issues.
In idle I have 35 - 44° - Blend 65 - 73° - Small 75° with throttling.

Here is my airflow setup (all on max) - anything to improve?

 

[Seanie280672]

When you added some more, it became too much lol, it was perfect the first time you did it before you removed the cooler again.

Ive been running Prime95 since 4am this morning, this is results so far:

Hmm tought the same but after removing it again it looked like to less in the middle. However I tried prime95 with both and temperature issue is still there 🙁 I am kinda running out of ideas.

It is strange, I would of thought that cooler was more than upto the job, are you monitoring voltages etc when running prime ? are they still on auto in the bios ?

 

[BlaaaBlaaaBlaaa]

Yes - everything still on Auto!
Just ran Prime95 again with logging enabled:

Short results:

[BlaaaBlaaaBlaaa]

Even in Cinebench I reach 75° and its throttling 🙁

it is very strange, your voltages dont look excessive, not enough to generate that sort of heat anyway.

 

[LeKeiser]

Way too much thermal paste. You put about the amount of 2 grain of rice in the middle of the die and you fix your cooler on top of it. The thermal paste will spread evenly then.
Use the latest RyZen Master (1.0.1 http://www.guru3d.com/news-story/amd-ryzen-master-software-v1-1-update-fixes-cpu-temperature-reporting.html ) to check the real temps of your 1800x.
My 1700x doesn't go higher than 60° with a Noctua D15s.

 

[BlaaaBlaaaBlaaa]

So my mainboard is a Gigabyte K7 and I just upgraded to Bios version f3 - newest (thought I already did that but nvm).
Idle temperature is now 55-60° with on the one hand is "good" because it explains why i get to 75° so fast and beginn throttling.
On the other hand this sucks 🙁 Even in the bios it shows 60° while doing nothing.

Do you think I should remove some/all of the thermal paste - reapply and check again? What else could I check?
Could it be a mainboard/cpu "hardware" issue?

Thanks again to everyone for trying to help me solve this issue!

Btw: Ryzen Master shows the same temps as HWInfo64. I just prefer HWInfo64 right now because Ryzen Master has some serious impact on Benchmark results.

 

[Seanie280672]

I wouldn't say you have a hardware problem, I would say gigabyte have not sorted bioses out properly yet, and the temp monitoring and sensors are all over the place, I would still remove that thermal paste and go back to an extremely thin layer, with the amount you have on there you probably have blocked heat from escaping rather than assisted

 

[BlaaaBlaaaBlaaa]

Cleaned up again:

New thermal paste:

Should be perfect now - correct?


Afterwards I noticed something very interesting:

First boot with default Bios settings:
Idle 30°- 35°
Cinebench 60° - no throttling
Blend 56° - no throttling
Small FFts 71° - no throttling

Reboot and enabling XMP to get my RAM from 2000 MHz to 3200 MHz:
Idle 44-45°
Cinebench 70° - no throttling
Blend - 65° - no throttling
Small FFts 75° - throttling

Testing without XMP to doublecheck:
Idle 30-35°
Cinebench 60° - no throttling
Blend 55° - no throttling
Small FFts 70° - no throttling

Testing with XMP to verify check:
Idle 40-43°
Cinebench 67° - no throttling
Blend 63° - no throttling
Small FFts 75° - throttling

What do you think? Which motherboards do you guys have?
The temperatures without XMP do not look to bad now - right?

 

[Barty1884]

How are you applying thermal paste???

It's pretty tough to find a decent image, but essentially this:

Then install your cooler (without spreading the paste out - the cooler will do that).

Then leave it alone. Don't remove the cooler.

 

[BlaaaBlaaaBlaaa]

Just added a little bit and spreaded it out with a old platic card. But should be fine or not? I kinda do not trust the paste to spread out itself 😛

nope, I agree with you, the top of the CPU is called the integrated heat spreader, and does exactly that, it takes heat from the centre (where the cores are) and spreads the heat out right across the whole of the top, to put a blob in the centre and then trust the cooler to spread it out right across the IHS is too much, which means you have parts of the IHS, edges mainly, not making contact with the heatsink and fan, or waterblock, way better and more trusting to just spread it yourself.

You've done it the best way, and temps are looking better, I spread it either by putting a plastic glove over my finger and spreading it around, right to the edges, or freezer bag or some cling film etc.

XMP / Higher memory speeds cause your cpu to heat up more as the memory controller in the CPU is working harder, also CPU NB voltage maybe raised slightly.

I did have a Gigabyte AB350m Gaming 3, it kept killing my RAM and giving major RAM issues, along with 2 other guys who lost 2 kits each on the same board, so I brought an MSI B350m Mortar, not had a single problem with it, just took me a week to get my full overclock completely stable, sent the Gigabyte board back for a refund.

 

[BlaaaBlaaaBlaaa]

Hmm quite a journey so far. I had a Asus C6H at first but the BIOS bricked itself. Afterwards I got the K7 I have now. About two weeks ago one of my ram modules died out of nowhere. I had to send back both and wait for new ones which took 1 1/1 weeks. So right now I am glad if everything is just working.

Refunding the Gigabyte board will not work that easily I guess as the two week refund period has already passed.
So I think I will leave everything like it is right now and look into overclocking/upgrading to second gen. after some time has past.

Thanks againfor all the help - Especially Seanie280672!
