I'm still under 24 cores

Postby Gratuitous » Sat Jul 07, 2012 11:13 pm

there is a locked thread here stating no one can run 8101 with less than 24 cores. this is not true. I can finish an 8101 in 2.3 days on my sr2 with 5682 processors which have 4 logical cores each @ 4.3ghz overclock. so there you go. you found at least one on 16 cores successfully turning in 8101. my time is 23 min 5 seconds per.

Actaully you can run 8101 on less than 24 cores - however you need a very high clock speed to complete on 16 threads, 24 threads (not real cores) needs westmere xeons @ 2.66Ghz or greater

So you are saying the dual 6128 I was fixing to build will not do the BIGADV?

I wonder if a 2p magny setup is really worth your money regardless of how you look at it.

Probably not, think I will go back in my cave...

That is not how I meant, I am relatively new to FAH and far from an expert, I am just echoing what I have learnt from others here, and from looking at stats.

If you want an AMD setup, it is better to go for 4p. Some of the overclocked 4p magny setups out there can get PPDs well above 200k. The main concern is the long-run costs.

While you may make an occasional one it does not appear from your stats that you make it reliably, so your sr2 at 4.3 Ghz with 16 cores will not fold them reliably and should not be folding them at all. Just curious, how many have you lost the sr2's are known not to be very stable at higher OC and lose WU's. So I think it is pretty safe to say no 16 core rig can fold them unless you are saying it is ok to only finish 1 once in a while and loose 1 once in a while while trying. :wink:

2 - SM H8QGi-F AMD 6xxx=112 cores @ 3.2 & 3.9Ghz
5 - SM X9QRI-f+ Intel 4650 = 320 cores @ 3.15Ghz
2 - I7 980X 4.4Ghz 2-GTX680
1 - 2700k 4.4Ghz GTX680
Total = 464 cores folding

yah, you got a point. I have 5 successfull and 2 lost out of 7 tried. my sr2 is not a dedicated folder it is mainly for cad rendering so i only have a few weekends here and there for fah. If I lose another one I will retern to smp. sound fair?

BTW I am interested to know if you consider this a heavy overclock at 170 bclk. it is only a 1.2ghz over. stock is 3.2ghz on these chips.

On a steady basis, that means you'll fall significantly below the 80% bonus requirement. In other words, you can't do it -- so, yes, return to standard SMP.

That's also what they concluded in the locked topic -- which is why I locked it.

i lost them because of OS not because of the machine. losses occured when i upgraded to wrong kernel. but I agree i have a 8101 at 48% right now. I will let it finish then decide if your recomendation is right for me. thanks.

Yes a 4.3Ghz OC on a sr2 is a heavy OC the sr2's are not know as the best OCing rigs out there they can be stable for days then for no apparent reason go bonkers, they are known to loose there OC on reboot also for no apparent reason. You may be lucky and have 1 of the good ones but that is a pretty rare occurrence. I tried 2 different sr2's at 1 time I hated those board's with a Passion, they would run good for a while then just go crazy, very frustrating. :(

yep, I have seen some of those reboot issues. I have heard that there is custom bios out for some supermicro boards. Are you aware of whether I could use these chips I have in a supermicro and get some overclocking? I wouldnt even consider switching boards unless I could get my chips to at least 4ghz though as I am about 98% happy with the sr2. it renders like a champ for me.

sorry to get off topic here Bruce. I will continue the opening thought when I get more data to prove/disprove my opening statement.

The custom bios is for 4P AMD boards none for Intel that I know of.

ok, gotcha. I cant quite justify a 4P build just yet. maybe next year.

Probably not wort it at this time since the 4P rigs are being forced to run the 8101's at least that is the way it was this weekend, apparently rigs with less than 16 cores are what is needed since they are still getting the 69xx WU's. If things remain the same I will be shutting mine down soon and firring the 12 cores back up. It is just not worth it running them on the 8101's too much power heat and headaches for too little. I am using close to 3000 Watts on my 3 - 4P rigs. I would not build a MP rig until we see what Stanford is going to do.
