Ahahaha tet5uo my i7 920 at 4.0 beat out your 965 by 1.739 seconds at 500m
Now go up your bclk by like 1 lol
Heheh it's on! :P
Srsly though it's a fast and dirty OC, I just used multi jacked up , my bclk is 133 still

Boo I don't think I can squeeze much more out of my cpu
As things stand it was barely stable at 4Ghz
But that doesn't mean I'm giving up just yet...

Great to see all these benchmarks!
*Just a note, I haven't actually been validating all these screenshots... too much of a pain... and I doubt anyone would try anything stupid this early in the game.
If enough people start to take this program seriously, I'll release the validator to a few "chosen" people. I might even re-enable it in a future public release if it is "hard enough" to reverse engineer.

Unless you're like me (who can use all that ram and still be begging for more), I wouldn't jump the gun just yet.
My current test build will comfortably do 1 billion digits under 6 GB of ram. (and still have ~700MB left for the OS)
So if you're willing to wait a little bit... (a week - a month?)
2.5 billion digits requires just over 13GB of ram with my current build - not gonna fit under 12GB.
I've had a few people tell me that y-cruncher is a memory hog... but compared to other pi programs, it has one of the best "memory / # of digits" ratios.
SuperPi needs 256MB of ram to do 33m. y-cruncher needs only 200MB. (179MB in my current build)
PiFast 4.3 needs 1.8GB of ram to do 250m at full speed. y-cruncher needs only 1.3GB.
QuickPi 4.5 needs 38.3GB of ram to do 2.5b at full speed. y-cruncher can do it in "only" 15GB (13.2GB in my current build).

Heheh It would be totally overkill for this system... I built it mainly for gaming , it also does a-lot of h.264 encoding for me as I'm backing up 1000+ dvd's to a raid array right now.
I'm sure neither of those tasks need more than my 6gb yet, lol.

Awesome! How much ice did you burn?
I've made some big (more than expected) progress on memory optimizations:
So 1 billion digits can be done with 6GB of ram.
I'm still in the process of massively testing this memory optimization. So I can't release it yet.

About a liter or so. I tried to get 4.4 but by the time I was done testing the ice was gone. I'm surprised at just how much heat that i7 can dump.
Good job on the memory optimizations, looks like I'll be able to do a 500m run with my 3GB of ram. Did the mem optimizations slow the computation time down at all or is it about the same speed (or faster)?

Wow... that's a lot of ice to melt through... lol
Go figure... that's the limit of water cooling? (I've never tried water cooling - always been scared of it...)
The memory optimizations shouldn't affect the speed much. As far as I can tell, it might even be a percent faster too. With the new version, I got a 7280s 10b time - with aero, sidebar, and @ normal priority. It used to take ~7360 +/- 30 or so seconds @ high priority...
Other changes so far:
1. I've added back single-threaded runs for benchmark mode.
2. I've added the program version # to the validation checksum.
3. The Validation.txt file now has the time as well. (It wasn't there before, because it isn't needed to validate the checksum. The time is encrypted into the checksum itself.)
I'm considering enabling the checksum validator in the next public release because I feel that it's "difficult enough" to reverse engineer.
Things that I'm working on:
1. I'm trying to find a better and more reliable way to detect clock frequency.
2. I'll be trying to implement counter-measures for the "slow-motion" cheats that are described here:
http://www.xtremesystems.org/forums/...ad.php?t=46926
All the cheats that are on that thread are obviously a very closely guarded secret. But one of the moderators was kind enough show me one of them so that I can try to counter it in y-cruncher.
3. Lastly, I'm doing a ton of stuff in the custom compute mode that don't apply to benchmarking.

WoW!!! 8.46125 seconds for 25m... This is starting to look more like the superpi numbers - except 25 x more digits!
That's four #1 spots!!!
Don't know what to say, but I can't wait to see what happens if a big overclocker shows up with some LN2...
*Though I am a little surprised that the 2.8GHz Gainestowns can beat the 4GHz skulltrail at the larger sizes...
Keep these benchmarks coming!!!
Even if you don't have an awesome multi-socket rig post your benchmarks anyway!
If enough workstations dominate the top spots, I'll split the rankings into single-socket and multi-socket divisions.

Thanks!
New version looks good so far. The reason why it's taking so long is because the memory optimization affected more than half of the constants in the program.
Specifically: both formulas for Pi, both formulas for Zeta(3), both formulas for Log(2) and Log(10), and the primary formula for Catalan's Constant, were affected by the memory optimization...
So I had to re-test all of these constants for both computation modes at a ton of different sizes... all the way up to 5 billion digits...
So my dual-Harpertown and Serotoninn's i7 920 didn't get much in the way of idle time these past 2 weeks.
Of course only the fast formula for Pi matters for benchmarking , but a lot of Pi-fanatics also play with this program (and it's other features/constants) so I don't want to inadvertently break some of the other constants. (There's this guy in Japan who basically gets brand new 20-grand workstations every year. I don't know what the primary purpose for them is, but he doesn't hesitate to tie them down for months at a time just to crunch digits... His current computer is a Dual Xeon X5470 with 128GB of ram... )
The tests are done now and the program is basically ready to be released. I've already compiled the version that will be released. Right now, I'm doing last minute checks to make sure I didn't break any existing code and to make sure that the improved anti-cheat protection doesn't give any false positives.
