Re: New chess rig

FYI, I flashed the BIOS to the latest version and then it worked (fortunately Gigabyte has a way to do this via USB that runs off a ROM and so does not even require a bootable system). --Jon Many new MB have this feature. It saves MBs from being bricked if the BIOS gets corrupted. This didn't use t...

How does this net fair against some of Sergio's more recent nets?

Re: TRX40 mobos

... Memory speed is not very important, the difference in speed I measured between 2133 MT/s and 3200 MT/s memory is at max. 5%, buying very expensive G.Skill memory with low latency to gain maybe 1 or 2% is IMHO complete nonsense. I see statements like this a lot. The first thing to note is the pe...

Re: TRX40 mobos

If you think you know something about my system that I don't please enlighten us. I think this will expose us to more substance than just your verbal diarrhea. I know that you either don't know how to reliably measure nps of SF or that you are simply lying, because gaining 15+% of average SF perfor...

Re: TRX40 mobos

On my system the difference between running the ram at 2133 and 3200Mhz was about 12% in NPS using stockfish. That was just for enabling the XMP profile. I got another 3-4% by tweaking the ram parameters even though I have crap ram sticks (crap meaning they don't overclock well). They're stable eno...

Re: Zenmastur vs Ovyron No it's not another GROB II!

I just took a quick look at how I played this game. I must have been completely delusional during most of the game. I can't believe how bad my play was. It wasn't obvious to me at the time. I was suffering quite a bit, but I had no idea how much it was affecting my play. I guess I should have just ...

Re: Data structure choice for TT

I guess this would be determined by the amount of pressure there is on the TT. If there is little or no TT pressure I agree there will be plenty of space in the TT. But this isn't the situation anyone cares about. When the TT is massively oversubscribed replacing the least valuable entry is much mo...

Re: Zenmastur vs Ovyron No it's not another GROB II!

This isn't all of the analysis but it should be enough to figure out what's going on. Not really :shock: - My problem with Qf6 is that white has many, many lines of defense and eventually they explode and I didn't want to have to spend weeks on a move to try to win. I never went over depth 38 for t...
