4770k overclocking.

Can get the CPU stable in adia 64 but not the latest prime95.
Overclockers overclock settings also dies in In-phase large FFT within a few minutes but seems stable enough to bench or game on. What method do you use? Got a really powerful water cooling on this CPU and have not used stupid voltages. Adia 64 works and I can run blend on overclockers settings but does fail. I am trying to get prime95 stable but not having much luck. vcore is 1.330volts (1.28volts bios) 1.195volts cache. 44x cores and cache 40x.

Adia stable 45x at 1.35volts bios and 1.35volts BIOS cache. Temps are low on average 55oC or less. Gets to 60oC in adia64. Don't want to do burn tests like mad encase I kill this CPU.

If it's stable enough to bench and game on, why bother with Prime??

XTU bench is good to use for stress for 24/7. It only takes 2 minutes to run, if you can pass it it'll be stable for any bench you throw at it and 'may' only need a slight bump in vcore for everything 24/7.

XTU bench is okay but I don't think its the best. Adia 64 seems better but people love prime95. Intel burn test is faster but everyone warns it kills Haswell chips.

Funny note the 1600 Ram overclocks to 2133 without the need for a voltage bump.

Not funny on auto settings the secondary and third timings are possibly being relaxed to give easier clocking on same volts. You need to test perf to see if overclocking RAM is actually helping efficiency.

All those synthetic progs are dros. Do what you need to do to test your PC is stable for what you need.

Understood.

Okay ram is getting 25GB/s + Sandra.

Working on dropping speed and better timings.

Aida 64 is okay but crashes on prime95 in a few seconds or mins. Not stable in prime 95 for any voltage or settings at 4.4x or 4.5x. Will give up as I don't want to degrade the chip.
