It always amazes me that some people would run the CPU/GPU hot rather
than run the fans hard. Fans are cheaper to replace, but I haven't had one fail
yet in 5 years, Just clean them regularly.

as long as you dont go higher than manufacture's maximum rpm then is okay,

A GPU a fan failure under warantee should be covered regardless. A failure
of a 3rd party CPU cooler could be blamed on the mobo for overdriving it.

I have my fan curves set for 80% @ 70C rising to 100% @ 80C. The cooler algos
(and cooler weather) don't run the fans as hard.

as long as you dont go higher than manufacture's maximum rpm then is okay, 24/7, 85% maximum i would go for. I do agree, if needed i would even 100% for few hours.

Well. Here is my experiment with Ryzen 9 3900X.

Processor: AMD Ryzen 9 3900X.
Motherboard: MSI X570-A PRO.
Memory: G.Skill Ripjaws DDR4 3200 CL14 XMP 2.0 ( F4-3200C14D-16GVR ).
Air cooler: Bequiet Dark Rock Pro4.
AIO cooler: EVGA CLC 280
PSU: Corsair HX1200i.

Out of box: 10500 hash/s

Memory DRAM Calculator for Ryzen v1.6.2. https://www.techpowerup.com/download/ryzen-dram-calculator/
Processor: Ryzen 2 gen
Memory Type: Samsung B-Die
Profile version: V1
Memory Rank: 2
Frequency (MT/s ): 3200
BCLK: 100
DIMM Modules: 2
Motherboard: X570

Calculate Fast.


Room temp: 23C

CPU: 4.0 Ghz @ 1.2V - 13150 hash/s @ 230W wall
Cooler:
Default cooler ( Wraith Prism): 90C
Dark Rock Pro 4: 75C
EVGA CLC 280: 67C ( 1200rpm fan )


CPU: 4.2 Ghz @ 1.25V - 13500 hash/s @ 280W wall
Default cooler ( Wraith Prism): +++ better dont try +++
Dark Rock Pro 4: 84C
EVGA CLC 280: 73C ( 1200rpm fan )






anything over 80c will destroy your cpu in a few months

My 3x ryzen 9 3900x all use water coolers.


I have  an

evga  cooler = https://www.amazon.com/EVGA-Liquid-Cooler-Cooling-400-HY-CL24-V1/dp/B074WH52BW/ref=sr_1_1?
corsair cooler = https://www.amazon.com/Radiator-Advanced-Lighting-Software-compatible/dp/B077G3C6HH/ref=sr_1_4?
fractal cooler = https://www.amazon.com/gp/product/B0719DHG5Y/ref=ppx_yo_dt_b_asin_title_o05_s00?

yet to test

cool master cooler =  https://www.amazon.com/Cooler-Master-MasterLiquid-Dissipation-MLW-D24M-A20PC-R1/dp/B075YPG52N/ref=sr_1_3?


and yes the corsair 280mm is best at 66C full speed
the evga  71c
the fractal 69c
what do you consider full speed? 4200 mhs is what i would consider
around 1.25 to 1.3 core to allow for close to 13k hash .  do you get 13000+ mhs on the water cooler?

What are the temperatures like with the stock cooler?
I was using the stock cooler with R7 1700 and I managed to get it to run @ 3.9GHz all cores but the voltage was so high and the power draw that it consumed around 210W from the wall, Veg 56 GPU was idle and temperatures reached 80 C.

Temperatures was quite hot 83C after working for about 30 minutes. But my room temperature quite low about 15c.
This was just overall test, ill have more efficient ram by end of the week.
Need to find that sweet spot where you reduce core voltage and not loose to much hashrate. To not get the CPU to hot with stock aircooler.

Power usage from wall is 260w.
   is it with the  gpu in idle?
GPU was idle yes.

Test bench setup :

Ryzen 9 3900x with stock air cooler

2x Gskill 3000 16gb C15 RAM modules

MSI B450 Tomahawk MAX motherboard

1xRX5700 for image

Superflower 750w GOLD powersupply

As there are few of the coins switched to RandomX mining algorithm already and one of them is Loki. So on stock settings everything out of the box we where hashing Loki at 11500 h/s. Which is about 5x then in our previous best tests with Intel i7 8700k out of the box 2360 h/s. Power usage from wall is 260w.

So we tried to push little more speed on the Ryzen 9 CPU , by overclocking it in motherboard BIOS. Changes done :

OC Explore mode to expert

CPU OC ratio to 4100 mhz

A-XMP to enabled

Precision Boost Overdrive to disabled

Play with DRAM timings (lower the values)

CPU core voltage to 1.250v

Increased Dram voltage 1.300v

This setting got me up to 12650 h/s mining RandomX. I was playing around with different kind of ram stick , and seen significant mining performance decrease with lower performance ram. So i have on the way 4x3600mhz 8gb stick and will do a proper performance test when they arrive.

So the 12650 h/s if you would be available mine monero today would be 3.5 usd , even that it got 10% price drop today. But you know it is not the case, impossible to predict what kind of total network hashrate will be when Randomx launches. As the total network mining structure will change and the current hardware will be unprofitable. Current Monero network hashrate is around 300 mh/s.

Profitability with Ryzen 9 mining Loki which is also RandomX mining algorithm. Daily profitability is 0.70usd

Im eager to see what RandomX mining will bring to Monero mining. What is your thoughts?
