1) Message boards : Generalized Fermat Prime Search : Help needed debugging! (Message 61307)
Posted 3043 days ago by Grutte Pier [Wa Oars]~MAB The Frisian
I know. The FTW runs with 1700MHz/1.075V and the SC 1526MHz/.950V and I lowered the voltage of the FW which runs fine on S@H and some other projects but there are some projects that just need more juice and as I said I think increasing the voltage to .950V might be the solution. Otherwise I'll increase it a bit more. The FTW however gets easily very hot.
We'll see but as for now I'm glad its running.

Which nvidia driver and boinc version is needed to participate in the Challenge ?

Before I had 7.0.28 icw 3.10.90 but got tired of the 0x000000EA errors.

So went back to 6.10.60 / 266.58 to try but now that doesn't work either.

So who can let me know which driver and boinc version I need to install to participate ?


The latest boinc version should work fine. The 6.10.xx versions should also work.

As for drivers. avoid the 295 and 296 drivers (this applies to ALL CUDA apps, not just GFN). I don't know about the 266 driver, but anything from 285 upwards, except for 295 and 296, should work.

The drivers and the boinc version aren't your problem, however. This is: (Taken from the stderr.txt output from your results)

Starting initialization...
maxErr during b^N initialization = 0.0000 (0.437 seconds).
Testing 23702^1048576+1...
Estimated total run time for 23702^1048576+1 is 13:45:25
maxErr exceeded for 23702^1048576+1, 0.5000 > 0.4500
19:18:16 (1448): called boinc_finish


That's the error you see when your GPU is failing because of excessive overclocking.

Lower the overclocking on your GPU (especially the memory clock) and the errors should go away.



I have a GTX460FTW and a GTX460SC which both run at stockspeed BUT the FTW with lower voltage so now I have upped the voltage from .925V to .950V which seems to have done the trick.
At the moment its running for more than half an hour.
As with GPUGRID, this project needs a bit more juice.

Why am I not listed in the standings? :( I have been crunching PPS LLR continuously before the chalenge even started and I still am .. one task takes about 45 minutes and I am doing 3 of them simultaneously ... makes me sad


Because only wus downloaded, processed and returned during the challenge count. You are processing wus downloaded before the start. Abort them, reduce your cache, join Aggie The Pew and you'll be fine


Or not.

But he could learn the rats something, so they would be fine, being a scientist.

Maybe even infect them with something ?

Don't think we keep these damned rats behind us this Challenge.

Need more powah.

Yes, the card was/is OCed and the voltage decreased to .882V instead of .95V at 54 degrees under load without a problem untill now apparently.

It's 216269. At the moment I'm trying 6.10.58 and 258.96 with S@H (later today try PG again).
Have installed XP32 again because I had an "nv******" (BSOD) error before.
Bit strang, the combo crunched without any problem before and suddenly I got errors without having changed a thing.


The other one is with a Gigabyte GA-MA78GM-SH board, 2Gb DDR2 and a GTX460FTW. 6.12.34 / 260.99 and no problems at all.
But couldn't find any info on the error so ........

Suddenly I'm getting a lot of these errors.
Have tried other boinc clients/drivers but no result.

Can't find it googling so no clue.


Asrock 870 extreme3 / PhenomII X4 945 / EVGA GTX460SC / 4 Gb KHX1600C9D3B1K3 / XP32

Systems are visible.

EVGA GTX460FTW 1GB/factory 850MHz/260.99/18:05

EVGA GTX460SC 768MB/factory 763MHz - now 835MHz/260.99/19:05

These are the fastest times, sometimes it will take more than 30 secs more.

A older driver will produce more PPD but in that case I can't use Afterburner to lower my voltages : FTW from 1.075 > .975 and SC from .950 > .887.
Crunchers without the need to adjust their voltages could try 258.96
