Swiss Tournament Programs

[Krzysztof Grzelak]

You're making me curious!

But first, good luck with the current tournament!

Frank.

Some issues have arisen, but they will be resolved by the start of the tournament on May 8, 2026. I must apologize to everyone interested in the tournament.

The next round was to take place tomorrow. I must apologize to everyone interested in the tournament, but due to a computer failure, the tournament will be canceled after the fault is removed. I sincerely apologize for the inconvenience. I will inform you about the start of the tournament on the forum.

Hi Krzysztof,

You probably mean the tournament will be resumed after the fault is removed. It's a pity that one of the computers has a bad memory chip, especially now the memory prices are very high, I hope the problem can be resolved.

Edit:

Are you sure that you need a 32 GB SIMM, or do you have eight 16 GB SIMM's sitting in that computer? If you have eight SIMM's you could temporary remove four, then there is still 64 GB left, I suppose that it won't matter much for the tournament.

It could also be a timing problem, if you have the memory overclocked with AMD EXPO, the first thing would be to try turning that off. In my experience overclocking memory does almost nothing, it only increases the risk of timing errors.

I have to wait a few days. Then I will know everything. I never overclock either the processor or RAM. The worst thing is that now it is difficult to buy new RAM. I have 8 sticks of 16 GB RAM.

I don't mean explicit overclocking, but if by any chance EXPO is enabled in the BIOS it could create problems like the one you see. Installing the latest BIOS for your mainboard could help too, sometimes the manufacturer (in your case Gigabyte) fixes DRAM incompatibility with a BIOS update.

If there really is something wrong with the memory it can only be a single 16 GB DDR4 stick which will cost you around 120 to 200 euro at the moment. If you have to replace a stick the best is to take one with the same timings as the ones already in the mainboard, even better is to take one from the same brand and type. The repair-shop you brought the computer to should know.

Krzysztof,

which programs played in the 3th round on the computer with the memory fault?
As this could impact results, although i assume probability is maybe low.

The following programs: Kingsrow 1.63, Truus voor Windows 1.0, Damage 16.1 NNUE, Maximus 2.02, GWD 4.26, Tornado 7.27a, Dream Gaia 1.4.

You are right and I agree with your opinion 100 percent. Program Memtest86+ showed 32GB RAM error.

[BertTuyt]

Krzysztof, thanks for answering.
The background of my question is related to the loss of Dragon.
According to my analysis, them main error from dragon was move 51. ... 33-29, which yields a loss, whereas 7-11 is a draw,
I hope Ed can also analyze the position/game.

I don't expect a program like Dragon to make such an error with a 8p DB, and 32 core search process.
So I though or the computer had a problem, or Dragon has a bug.
Not impossible that Michel was not able to test 32-cores, so the program still has an issue with this number.

But I will await the verdict of Ed.

I think I will revert to version 4.6.2 in the tournament. I noticed that Dragon has huge problems with the ending database.
