Is this considered stable?

[zm15]

I recently overclocked my i7-860 to 4 Ghz with 1.275v. I keep getting rounding errors in prime95 and the workers stop after a few minutes.

The rest of my computer seems to run fine, so I tried a 2 hours long Cinema 4d render with the CPU's at 100% the entire time and it didn't have a problem.

I'm not a gamer and the only reason for maxing out the CPU would be video encoding.

Even thought it didn't pass prime95, would this still be considered stable?

Hi.

Try with LinX for more that 2 hours, if you can, overnight or 12hours+.

prime95, LinX and generally stress test programs use the 100% of CPU, something that any program or game can do yet, so, in that point I will say that your overclock is stable.

For me that's a big HELL NO!!

While it's true that stability-testing programs work your CPU more than regular programs do, it's still best to not have errors. That way you can be confident that during your normal activities your CPU won't be throwing small data errors here and there. Enough small errors happen, and you can have data corruption on your hard drive.

My stabiltiy test routine consists of:
1. 24 hours of Prime95 Torture Test on "In-place large FFTs" setting.
2. 50 runs of IntelBurnTest v2.50 on Maximum.
If it cannot pass both, it isn't stable.

Well update, it eventually did BSOD after a little over 2 hours.

In general, is it better to go with a higher multiplier and lower BLCK, or vice versa??

I only have DDR3 1333 RAM, so not all that fast for OC'ing.

If your core temps are within limits, at 1.275 volts, you still have some room to increase core voltage.
