Probably just me being blind...

It's only available in the full version under EEPROM

So @ 2666Mhz I can do 14-13-13-13-31

What steps should I take here? Talk to me like a lamen redface.gif

As for SPD info, my sticks looks fine. I think?

The rate of coolant flow should be set to achieve the desired delta-T between the cooling block and the fluid. In the static case, no matter what that delta-T is chosen to be, the heat into the pool will be constant. And to pull that heat out of the coolant heat exchanger at a sufficient rate (for its size) to meet the allocated delta-T at the refrigerator end, the refrigerator side will have to do its thing keeping the pool cold enough. This affects the refrigerator design. Given an old refrigerator, though, some parameters are fixed. For example, a given refrigerator may be designed to pull only 50W [number picked out of the air to make a point] of heat out of the refrigerator because it expects the door to be closed most of the time. In such a case, this refrigerator won't be adequate to cool a 150W Ryzen load. Ideally, you would want to sort of match the heat load if using an old-time compressor, because those didn't like to be started and stopped every few minutes. You might need a modern variable compressor such as Perlick uses in their Signature series of bar refrigerators.

Alternatively, using a sufficiently powerful old compressor for the refrigerator side, one might want to cool down a large thermal mass to a low temperature using a long cycle time (low bandwidth loop), and then control the CPU coolant loop flow rate to keep the temperature of the post CPU fluid constant (higher bandwidth loop). All of the possible configurations would need to be evaluated for cost-effectiveness depending on one's goals. I'm imagining a need for a 24/7 folding or whatever PC that needed a solution that didn't require any fiddling once set up, and didn't incur the wrath of a spouse or parent.

It would probably be fine if the small system was designed to only cool a small space like a freezer compartment efficiently. This small space narrows down to the PC cooling radiator(s). Without trying to aim for 0c cooling it may be enough to not cause freezing or condensation if the system operated with the enclosure opened. For optimal use it still would take a more custom setup that allowed control of the cooling unit's up time, so that its not always on during idling.

I'm tempted to get the cheapest portable freezer available and stick my cpu cooler radiator in it.

Now I suppose put bclk to about 140, or whatever it is you need for at or around 3200mhz at the 2666 ratio redface.gif I haven't tried such a thing myself. GL.

Yup I decided to go ahead and do that too. Just to be safe. Whole machine behaves better now starts better. But really what a situation, with hindsight we will look back on this and laugh deeply......

 

"They did what! Unfinished utterly broken, dangerous software released to the public that meddles with the SMBUS and SPD!  Bwahahaahaaaaa, bunch of nutters!"

I wonder how much it will cost them in the long run.

I'll try it. thumb.gif

Should I put 16-16-16-16-36?

nothing, since instead of RMA you all bought software to fix it yourselves biggrin.gif.

See if you can get 3200 to post at 14-14-14-34 first biggrin.gif

It's time to get some shares from @Voodoo Jungle ... smile.gif

And as @Mumak said, there is likely no fix to it. If they cant fix the software to not corrupt the SPD data it for stupid reason needs to access to control the lights, then its lights out on the idea. Time will tell if they come to a safe solution.
