Official Superpi Mod Ranking Thread

Holy crap Batman! I just noticed how 87dtna got his 555 up to 5Ghz! How did you do that?! I can only get mine to 3.8 before it crashes!

Dice maybe...didnt really read the thread in depth enough to see whether he was running air or dice.

Yup that was a DICE run. But voyager you probably have a C2 stepping then? My 555 is a C3 and can do 4.2ghz on air no problem.

I'm pretty sure I clicked the one on the first page of the thread for AMD...

Nope it was in the intel spreadsheet thats why I said something! I'm sure bomber will fix it.

I've got the 555 Black Edition. I have no problem with temps. It just starts to crash when I hit 3.93.

Yes yes, I have the same chip but there are different revisions. Open CPUz, stepping is over on the right side right below the Phenom II symbol.

You'll either have a C2 or C3.

What kind of voltages are you running when it crashes at 3.93?

The link you gave in a C2 stepping 955...don't get that one.

Look for the M in the part number (before BOX), the C2 is an I.

Yea I know that, but nowhere, as in not from sites/shops I would be happy to trade with, sell the C3 stepping. I may get one imported instead, the price they are in US would mean shipping would have to be ~£25, which it deffinately won't, for it to even be a similar price
 
ive got a c2 stepping 955BE its quite irritating to get it to 3.8ghz as i have to push my vcore higher than im willing to go... it stays stable at 1.4125V but i lose my C&Q support. so i typically just leave it at 3.6ghz @ 1.375V

it does drop my times by about a whole second to do the extra 200 mhz oc, but i cant warrant keeping it at 3.8ghz with C&Q getting neutered :/
 
Nice work, Susik!

That's a pretty amazing CPU you've got there... 4.5GHz at 1.36V even with HT off is insane.

I'll work on knocking you down though. ;)

1.4 is nothing to an AMD processor. As long as temps are in check I have no problem running Phenom II's right up to 1.55 sometimes more on good air cooling. I have never fried an AMD chip, they can take the volts.

Short term "suicide runs", yes. Running those volts long term or 24/7 your going to cause electromigration at those volts.
 
Well yeah I meant just to run superPi, sorry for the mis-clarification. I personally set 1.425 my max Vcore for AMD processors, I ran my Phenom II 550 unlocked to a quad at 3.8ghz on that voltage for months with no issues.

SPI doesn't load the CPU as much, it's only a single threaded app so only 25% cpu usage for a quad core 33% for a triple core etc so you can go higher for a ''suicide run'' with SPI because temps won't be anything like prime95 or something that loads the CPU 100%.
 
I just dont like the fact that it totally disables C&Q for no apparent reason on this motherboard, i dont like running at 3.8ghz all the time, i would like it to step down to 800mhz on idle...but it just doesnt do it for some odd reason...

so for the time being im just running it at 1.375V which is a nothing bump at 3.6ghz, which seems to be the sweet spot for my chip...its not a huge overclock but i dont want to damage it...

when i hit 100 posts ill post a run i suppose, just really kinda pissed i can hit 3.8 but i cant really get the damn thing to keep using C&Q...probably would work with RMClock but they havent updated that in years...

-submitted a score a few days ago, waiting for a update to the list

Well there's no way i'm beating your score but when i've hit 100 posts i'll give this a go.

I know I can do under 10 seconds.
 
Turn hyper threading off your CPU, you'll get higher clock and lower temps for a given voltage. You should be able to easily get in the 8's around 4.5-4.6ghz, which you should easily be able to get around 1.375 Vcore or so with HT off.
 
Guys, atm im on my phone, as i have been on vacation, and i cant quite update scores. Scores will be updated sometime this coming weekend when i get home from VA.
 
Just submitted my score but i made a mistake in the effective memory clock. I put 888mhz but that's what it's at during regular use. During the super pi the memory was running at 972mhz.
