This is performance=) (2 module saturn)

is that  494gh/s for a oct. saturn.

Can we put as settings 221 or only 231 211?Huh

Yes you can.. I don't have easy access to the post but a number if times earlier in the thread a table with a more comprehensive list of numbers with associated clock rates was published. Last one was perhaps 2-4 pages back.

The list again Smiley


First column is speed in MHz per CORE
Second or third column is setting used for speed in column 1

Code:
700.0   1B1     372
712.5           382
725.0   1C1     392
737.5           3A2
750.0   1D1     3B2 << stock Oct speed
762.5           3C2
775.0   1E1     3D2
787.5           3E2
800.0   1F1     3F2 < first example below
812.5           402 < second example below
825.0   201     412
837.5           422
850.0   211     432
862.5           442
875.0   221     452
887.5           462
900.0   231     472
912.5           482
925.0   241     492
937.5           4A2
950.0   251     4B2
962.5           4C2
975.0   261     4D2
987.5           4E2
1G      271     4F2


EX:
for 800.0 MHz you could use a setting of "1F1" _OR_ "3F2"
for 812.5 MHz you would use "402"

core speed x 48 CORES  x 4 DIE will give you the Gh/s per ASIC x # of modules  - HW error %
= what to expect @ the pool

800 x 48 = 38400 (MHz)
38400 x 4 = 153600 (MHz)
153400 x 4 (assume a Jup) = 614 400 MHz

Subtract the HW errors (percentage) from the total above and you should be close to what the pool reports.

Smiley
YMMV

humble thanks goes to ncs0ne.

I wonder what to do with knc, would like to buy jupiter bu hashrate is exploding at a pace that nothing seems reasonable. Perhaps I'll just help community by running bitcoinqt.

It would be fun to overclock neptune, anyone donating theirs to me?  Cool

Yes you can have all the Neptunes I ordered!

Ok I helped all you guys out, see if you can assist.

I just added a 4th module to make a Jupiter and of course with my luck it has a Dead Die 0

I am overclocked to 231

As soon as I try 241 or 251 dies start getting shut down due to HW errors.

As you can see I have the temperature covered.

Whats your suggestion on settings? What should I adjust in advanced?

This is a October Saturn/Jupiter with 4 VRMs

Thanks for any suggestions

I have done the same with one of my older units.. With the voltage control on the dies I bumped everything to about -0.0860 volts to keep it stable and keep the dies alive... I did have a troublesome die  that simply would need a lower OC than the 241 I am running on most so I would drop it to 211 to keep it stable..

I must have missed the code on how to change OC on a die by die basis.

How can that be done?

in theory this is true? because my KNC only reaches 221/ 648GH ...

Have you not tried increasing the voltage just on that die? Works for me
