Overclock crashing during games

Hey guys,

Thought I had a stable overclock (4790k) at 4.7ghz @ 1.29v, did all the right tests for the correct amount of time. Started playing Guild Wars 2, and it froze and restarted so I've dialled the volts to 1.3 (not too concerned the life of the processor, I enjoy building computers so will probably upgrade within a year- year and a half) and dialled the clock back to 4.6ghz.

Anyway, are there any GPU benchmarking tools that will stress the CPU too? Keeping it stable for an hour or two gaming session is basically my idea of stable- I know it will differ from user to user.

On a side note: will DRAM voltage effect the stability of an OC'ed CPU?

Yes dram voltage will affect the CPU, if you don't accommodate the HT link and NB then stuff is going to go wrong. You can try running Unimagine valley. if not just run 2 benchmarks 1 for cpu and 1 for video at the same time.

Sounds to me like it could be ram, I would reset ram back to what it was initially.
 
Anything overclocked to a higher amount than what it is quoted to work at it`s stock speed.
Requires a slight increase in voltage in a lot of cases in order to keep it stable when load is applied to it.

One device and it`s voltage setting should not affect another device.
Unless the power supply unit in some way and how it distributes it`s power, is faulty or underrated to power all of the devices, and not fully stable.

Cheap in other words.
The freezing can be down to a simple fact that the memory of the system is being pushed too hard in operating speed in MHz where you will start to get memory errors due to the latency timings set on the memory. vs the frequency it`s running at, if pushed very high in clock speed.

I haven't the dram voltage, left it on 1.5v (Corsair Vengeance 1866) should I up that to 1.65? Once I finised the OC I set up ppwer saving and XMP to run it at its rated speed.
