Hi,

I've recently purchased a new gaming rig and decided to up the frequencies a bit.

I managed to get my GTX 780 AMP to 1403/8150 (1141/1630), but there is a slight buzzing sound while the card is under load (it persists even if the card is set to default frequencies, so I guess that's normal?)

I got my 4770k stable on 4200Mhz with a multiplier of 42 (bad luck of the draw), running on 1.200 volts when set on manual (I can set multiplier to 43, while running 1.275 volts, but it's not worth it).

Now the problem is, as soon as I set the auto adaptive mode, it bumps my voltage to 1.274 (while running AIDA64) and if I try to adjust it manually I can only go as low as -0.030, without experiencing system failure (I managed to get into the system a couple of times with -0.035 and -0.040, but it was unstable)

My proc is currently running at 1.245 while under load, which is fine, but it's no where near 1.200 I manage to get on manual.

Also bonus question, I got a Corsair 760AX with a combo PCIE (6+8) pin cable, is it ok for me to run my GTX from a single cable/PSU slot, or should I plug two cables using two different slots?


Thank you for you help and feel free to answer any question you may know!

Don't use adaptive during stress testing, use override, then switch back to adaptive when you're done.

I don't understand your psu question. You may need 2 plugs for one card but not 2 slots.

Hey,

I'm done with stress testing, my CPU is limited to 4200/4300 Mhz. The problem is, with adaptive mode, I can't go under 1.245 volts.

As for the PSU, it's a modular PSU (it has cable slots), and one of the cables has 2x PCI-E 6+2 pins. I was afraid I might overstress a single PSU slot if I run my GTX from a single slot, with a single cable. (as far as I know each of the slots has a wattage limit)

Check your power options in windows. If set to performance the voltage will be kept high, even though you have selected adaptive mode. To allow more voltage flexibility select the "Balanced" power option in windows.

Hey, I checked it's set on "Balanced" already.. =/
Any other ideas?

What load are you referring to when you say it's at too high voltage under load?
If you get the higher voltage during load testing on Aida or similar, then it's perfectly normal behaviour.
On normal applications the voltage should hold the maximum set limit.
It's the AVX commands that the stress test programs use that make Haswell CPUs increase voltage when
in adaptive mode, but that should not happen on normal apps.

There is also a minimum limit the adaptive voltage can be run at. If you put in a number below that minimum limit,
then you will still see the "real" minimum on any full load. When you set the voltage higher than that minimum limit,
your set limit will be kept always, apart from those stress test programs. This minimum voltage on adaptive is not
the same on all CPUs BTW. People have reported anything between 1.16 and 1.24v limits.
Of course, on manual volts no such limit exists.

You can run HwMonitor in the backgroung so that it logs your max Vcore voltage while you run your apps and benchmarks and what not.
The you will know the real life voltages that are in use when you actually use your computer.

Hi,

I'll try that tomorrow and make sure to post my findings here! I thought that AIDA can't add extra voltage, because when I set the voltage manually to 1.200v it stays there even while running the AIDA stress test, but when I set it to Adaptive the voltage gets bumped up to 1.274v.

I also can't get my chip higher than 4300Mhz, but that's another story, must be a bottom range 4770k chip.
