Presumably, my choice of cooler makes the cpu more hot than it would otherwise, but I was hoping I could work with this. I just find it confusing that the computer shuts down when the cpu temp is near 70 deg C (iirc) and when the cpu socket temp is 73-75 deg C (both when during stress testing). There seem to be a temp limit and I don't know what to do with it.

I don't understand why the cpu socket temp is so high if the cpu temp is lower than socket temp.

I'll try liquid metal TIM, a 60x60x10mm fan on the backside of the motherboard, and some better case fans.

How many watts is that cooler rated for? Ryzen is rated as a 95 watt CPU, so if your passive cooler is designed with 65 watts in mind, that is where your problems come from.

How are you measuring the CPU temperature, since the BIOS reports 1700X and 1800X as being 20 degrees C higher than it really is(causes issues with fan speeds and such).

Looking at this again, what CASE are you using? The product documentation clearly hints that you need a case with a good amount of airflow for it to work properly.

Just installed 1107 and noticed the CPU throttling at 78.6° tctl, 83° SIO, and 55° socket on a 1700 with SenseMi Skew disabled. I do have PLL set to 1.94v which didnt cause skew issues in the past with it disabled. I'll do some more testing shortly but I've never observed this behavior before on 1002-0082 BIOS versions.
Warning: Spoiler! (Click to show)

Edit: Set PLL to 1.8 and still observed throttling (along with some instability likely due to my 130mhz BCLK @1.8).

Edit 2: Increased vcore one tic (1.394 under load from 1.387) and set SOC LLC to level 3 and the throttling is gone even though temps have increased by a few degrees. I've still never observed throttling with either situation but it seems to be gone for now.

Edit 3: something else it has never done before is freeze up momentarily during benchmarks which is happening now even at BCLK 120 with the RAM at 3200.

Before I started BCLK overclocking yesterday, I re-watched the YouTube by Chew using this board. More than the specific BCLK, CPU frequency, volts and memory frequency, I wanted to get more familiar with his basic setups.

Here is what he did:

Disable CPB and Global C-states under advanced (he was not going P-states)
Set all PCIe to Gen1
Disable Super I/O Clock Skew
Set AI Overclock Tuner to Manual
Set BCLK value
Set CPB to to Disable
Set CPU LLC to Level 5
Set Spread Spectrum to Disable
Set CPU Power Phase Control to Optimized
Set VDDSOC LLC to Level 3
Set VDDSOC Phase Control to Optimized
Set DRAM VBoot to same volts as you use for DRAM
Set VTTDDR to 0.68640
Set VDDP Volts to 1.005
Set CPU Core Volts
Set CPU SOC Volts
Set DRAM Voltage
Set PLL Voltage to 1.8
Set SB Voltage to 1.05

Save / Reboot

This was a good starting point for me. I'm on UEFI 1107 as well, and like you have SenseMI disabled and see temps under stress in the same ballpark as you are. The only freeze ups I see are in Realbench Stress runs, and that is something I noticed before using 1107 or BCLK overclocks.

prime tested for more than an hour at it looks nice

my memory is 3200 cl15, will I have problems if keep running it at 3383mhz?

can i push it more? biggrin.gif looks very stable with prime and with intelBurnTest.

All good stuff for extreme overclocking I'm sure but I'm comparing this to settings I've used in all of the other BIOS without issues. I expect to have some variation BIOS to BIOS but certainly didn't expect to see the stuttering/freeze issue. VTTDDR should be half your DRAM voltage so .71 range for me.

I understand (although he was showing his setup for regular overclocking using an air cooler, not the out there Extreme LN2 stuff.). I'm sorry I can't offer an answer as to why you are seeing the behavior specific to 1107, it has actually been more stable for me than previous versions.
