Safe haswell voltages

[McstylisT]

Hi peeps,

Just basically upgraded my board to a MSI Z97i gaming AC , really working a treat for me. Fine board. I've also changed case to a Obsidian 250D , and using an old H80 cooler in push pull.

Now I've managed 4.6ghz on my 4670k, tightened my ram down to usual 10-11-10-27-1T @ 2400mhz.

At 4.6ghz I'm using 1.31v on core / 1.19v on ring / SA volts are 1.065 / all other dig/analogue/ are around 1.025v. The vvci input voltage is at 1.94v

So what are the exact limits here, as this little board wants more I can feel it. As mentioned using h80 and doing normal usage and benchmarks such as cine bench and super pi it's max temp was 67 degs.

Thanks, more detailed info welcomed.

Convert a DVD to Mp4 what temps do you get when using Handbrake?

Its generally said 1.3V on air/aio's, so just keep an eye on your temps

Hi ,
We'll I could do never bother with any encoding nowadays , killed it many moons ago. But will give this a spin when I get a chance, free to use yeah ?

That's was my understanding, though seen a few with closed loop / custom with much more, as long as the temps are in check this was not dangerous. Was looking to push 4.7 but thinking 1.35v is too much.

What about the rest of the voltage options, anyone have the safe and max limits on them ?

McstylisT I've just purchased the same motherboard / CPU and haven't had much joy overclocking (didn't really spend too much time on it to be fair).

Just me being lazy but I'm sure it would benefit others who jumped on the same deal for you to share all of your OC settings to get to 4.6GHz ?

Yeah when I'm at the puter later I'll get some snaps of the bios for ya.

Though individual CPU has a lot to do with clocks on haswell.

Dont seem to have a bios snap function, and my phone does not show the text properly from the shots ive done. But i wrote them down.

Let me clear this up, I dont run prime/ibt on haswell chips so not saying this torture test stable but user stable.

Passed Realbench/Cinebench/superpi/sandralite tests

VVCI - The top option. For 4.6ghz this is @ 1.945v
Cpu core - This is @ 1.31v
Ring voltage is @ 1.2V
Ring frequency is 4000mhz or 40x
SA cpu voltage is 1.185v
IO cpu voltage is 1.165v
Analogue cpu voltage is 1.165v
digi cpu voltage is 1.165v

The others are set to AUTO ,,,, Apart from Dram voltage which i have 1.7v

Will try and get some more decent shots.

Any others have any input of the voltage uses here , id like to know what you think.
