Re: Can somebody compare the AMD Ryzen processors to the intel processors

Nice result. I am thinking about getting a 3700x, but I don't want to OC it. How would it do it without OC? At that frequency, do you need a special cooling system for the CPU? It's not really an overclock as I see it, more like a constant frequency which I prefer. The CPU is stable at 1.225V so it...

Re: Can somebody compare the AMD Ryzen processors to the intel processors

AMD Ryzen 9 3900 (avx2 binary): SF nnue off: 1399478 nps SF nnue on: 1830004 nps (!!!) = using nnue is 131% speed compared to nnue off That looks too good to be true. This is what I get on my Ryzen 9 3900. Fresh booted system, offline. Amazing results. :shock: Could somebody do the same test with t...

Re: Happy New Years!

Here is to the end of a very challenging year. May you all be happy, healthy and safe in 2021! https://i.imgur.com/SWRpWDd.gif Thank you very much, Joshua! And I think it's a really good idea, to wish some or many good years (plural) at once, why always stick to a single one only, because just one ...

Re: AVX2 optimized SF+NNUE and processor temperature

I was obliged to lessen the settings of my Ryzen 9 3950x because after some time it was frozen during test run (SF+NNUE against SF+NNUE) because of over-heating the CPU (CPU temperature was more than 90 degrees Celsius with Noctua NHD15 SE AM4 air cooler) Now the CPU clock is 16 x 4.0 GHZ (It was 1...

The system came to us with SMT "Auto." We then "disabled" SMT to run a few tests and then went back to BIOS and toggled it back to Auto, but it still operates with SMT disabled.

Has anyone solved this problem?
Try and turn it off and then back on again.

Re: Severe windows 10 problems. What to do?

Well, maybe I was a bit harsh, I'm sorry for that. The point is that manufacturers want you to buy their stuff and sales people just tell you what the manufacturer tells them. I didn't mean to say that sales people are incompetent to sell stuff, but most of them have no clue about the tech behind t...

Re: Severe windows 10 problems. What to do?

Yesterday I bought some loudspeaker cable, there was an arrow on in, the guy told me that the arrow should point in the direction of the loudspeaker because the the signal goes from the amplifier to the speaker, of course I told him this is complete nonsense and the guy got really mad at me.

Puzzle. Suppose a search takes X nodes and the hashtable is 2^n in size. You would like to be 95% confident no two nodes have a hash collision.

What’s the formula connecting X and n?
This will occupy my mind for days and in the end I won't be able to solve it, thank you very much.
