Recommended SF5 parameters?

[cma6]

I would appreciate recommendations from the experts for recommended SF5 (with Syzygy bases) parameters to be used on the following system for infinite analysis, averaging 10-20 minutes/ply used for correspondence chess:

Intel i7-4930k with 6 cores O/C to 4.4 GHz with 32 GB of RAM on Win 7 Pro, using large pages.

Currently using for SF5: hash = 4.096 GB
minimum split depth = 0
Ponder is checked
Syzygy Probe depth = 3
Syzygy Probe limit = 6
Threads = 6

Thanks in advance to the experts.

I'm not an expert, but why not use a larger hash setting? 8192 MB at least. Minimum Split Depth = 0 is a placeholder, which will be replaced internally by 4 on your system, which is probably fine.

Very useful!

Very useful!

Was just a joke, man ! I'm a fan of "exotic" chess engines. Pulse, Cave, Sunfish, MyTeacheR & co. are my great interests in computer chess. Monsters like Stockfish aren't on the first place on my agenda !

Have a nice day !

Have you tried your proposed setting? I doubt it.
What about learning by doing?

As an senior EXPERT I would recommand:
Do not change hash size ( well chosen by developers)
minimum split depth = 0 (zero is always good)
Ponder is checked (most experts use POFF)
Syzygy Probe depth = 12 (choose number of processors)
Syzygy Probe limit = 0 (let SF5 decide what do do)
Threads = 36

Consider bying a xeon system.

You are quite clearly not an expert. Any expert knows that adding more threads than physical CPUs ends up giving you less performance.

I'd give Stockfish 16 gigabytes of hash, though you probably won't use it all.
Minimum split depth at 0 will correspond to 4.
For infinite analysis Ponder makes zero difference. It's used for engine-engine games where Ponder is whether the engine will think on its opponent's move.
Not familiar with Syzygy options, so 0 is probably fine.
Threads should be 6. Any more increases NPS, but not time to depth.

1.-sEnIoR eXpErT ? WOW !
That's a new joke in this thread ?

2.-If you have the 6-piece tables, set the value of "SyzygyProbeLimit" to 6 (the default). If you only have the 5-piece table, set it to 5. Set the value of this option to 0 if you want to temporarily disable tablebase probing.

Hoping I was (a bit) useful !

Have a nice day !

There are so many things wrong with this post...

[Dicaste]

There is no recommended settings. Just change the values and try. You can't expect values work exactly same on different computers.
