Ideal MHz to fold at

post #1 of 18
Thread Starter 
Hello all. Perhaps the most experienced folders can answer this. I'm currently folding SMP with a 2500k at 5100MHz. I realize that this is probably a higher frequency than most are folding at. But I'm only at about 1.376v, so I have some room to go higher.

I know I can get to 5.2 or 5.3 and perfectly stable, but I'm trying to decide if it's worth it. It will take some time and some tinkering. The average WU takes me around 4:45 - 5:00 hours to complete. If I will only shave 4 minutes from the time it takes to complete it than it's probably not worth it. If I gain say, 25 minutes than it is worth considering.

Maybe someone else has tried to figure this out and knows an easy way to calculate it?

+100mhz would reduce a 5 hour work unit to 294 minutes. 6 minute difference.

If its stable with reasonable voltages and temps, higher frequences are always better.

For SMP it will be different for each WU because the sooner you complete it the more points you get from the bonus which is based on base points. Increasing the speed to 5.2 would be a 4% increase in speed which might actually give you 6-8% higher PPD (although that is a guestimate). If the rig is not used much you can probably do -bigadv and see huge points from bumping up to 5.2.

Honestly though if you use the rig frequently its not worth it. I could probably get my 2500k up to 4.9 stable but the time it would take to find the right combination just is not worth it so I am sticking with a 100% stable 4.7.

I would be more concerned about power consumption vs ppd. the higher frequency you need, the more voltage you will need.
as you peak 5ghz, each increment of 100mhz will require a greater increment of voltage, meaning you will draw more power per mhz.
folding for a longer amount of time at the same cost is worth more in the long run.

Thanks man! I would love to take all the credit, but I think I just got lucky. I chose the best board and got lucky with the chip. I sometimes see people having difficulty getting past 4.5 and wonder what exactly is their obstacle.

What does the amount of use the rig gets have to do with it. I see no lag at all when the program is running. I does a pretty good job of giving up CPU cycles when needed.

Your board appears to the the "binning" board of OCN, I think the OCN binners use that or the Gene-Z.

lol I have a bit of a 4.8Ghz and beyond obstical myself. Odd considering I can roll 4.6Ghz at just a touch above stock volts. Not complaining though, 4.6Ghz is where I wanted my 2600k for 24/7 use before I even bought one, that was the plan.
