Anyone running Boinc overclocked?

[SaladFingers]

I haven't had any luck with that. Both my overclocked GPU and my overclocked CPU will cause random BSODs. I disabled the usage of the GPU, removed CPU overclock, and it works reliably. Tried only a tiny bit of OCing and it BSOD'd again. Anyone has any luck? Or is overclocking a no-go for this kind of workload?

3.3ghz (from 2.4) on the CPU and 1500mhz on my 970 (or 1440mhz, if I use a particular app).

 

Also have a pentium with 2.5 instead of 2.0 Ghz.

 

 

Did you add voltages?

Yes, I was running at 1.285 and passed all stress tests without problems. Upped it to 1.295 to help. My 970 is also overclocked btw, 1531mhz, but seriously it can't even do 10 minutes of crunching before it crashes lol. I just wanted to isolate the CPU for starters, so I disabled GPU crunching altogether.

 

Currently running at 4.5ghz @1.295, ran several stress testing software for hours and hours, not a single error produced. The stock speed of the CPU is 3.3ghz, turbo speeds are 3.8hz. Even if I overclock it to just 3.9ghz, Boinc will crash at some point sooner or later. I'm pretty stuck

Do you have XMP on? If so, then put your RAM back on 2133mhz while you do your testing. It MIGHT be the cause.

 

Also, which project are you crunching?

I tried with both XMP on and off. The ram sticks are 2666mhz. When XMP is on, I use a multiplier of 45. When XMP is off, I raise the BCLK to 125 and lower multiplier to 36, and ram at 2133 which ends up being 2666.  I raised my voltage up to 1.320 and it appears to be more stable (runs for longer) but still crashes at some point. I am mainly crunching on the SETI project.

THAT. Run your RAM at 2400 / 2133 and see if it solves the issue. If it seems to run stable for longer, it's probably the cause of crashes.

 

Yes, I know, your RAM is rated for 2666 so it should work at that speed..... but that doesn't mean it actually is.

 

There's a recent report on PrimeGrid's forum of a guy that has 3200 rated RAM, but only works on 3000mhz. Like wise, the 550ti in the past had to be underclocked (even below Nvidia's oficial speed ratings) in order for it to crunch reliably.

I guess I will have to try with the Ram lowered to the default 2133mhz. It just doesn't feel right Anyway, will post more info after I'm home and get to do some more testing. Thanks for your on-going assistance so far

Runing 4.4 from 3.07 stock, with stock gpu 7990 and oced ram to 1800 from 1333 and all stable. It's your overclock that is unstable. Do longer tests and you will find your 24/7 sweet spot as in games your cpu and gpu is not used at all times as much as in rendering/boinc and so on.
