Good Vol. To Start At?

[AMD Lover]

Whats a good voltage to start at with a 4770K on a H100i shooting for 4300Mhz/4.3Ghz

 

Don't pay attention to sig its old

I think maybe 1.2-1.5 seems safe.

[AMD Lover]

I'd start with 1.3v

Isnt that the max you want to go or is it 1.4v

Start low and work your way up.  Don't have goals when overclocking Haswell, go into overclocking with an open mind.  Haswell is such a crap shoot, that you just have to get in there and start experimenting.  Use a guide, here are two very good ones:

Just because you have good cooling, doesn't necessarily mean you will get good results, it depends on your chip.

This is the unfortunate truth, damn silicon lottery. I was lucky enough to get a 4790k that would go up to 5.02 GHz on a quad Alphacool radiator in a cold room running at mid 80s temps and 1.37 volts (both way too high for me for any long-term OC) If you get to 4.7 at low 80s temps you're doing well.

Yeah well it runs at stock unless I'm rendering a family vacation movie presentation or working on my research application. It plays GW2 and Diablo 3 on its own at medium settings so I'm more than happy. No more loud graphics cards for me.

OCCT, IBT, Aida64

We need like a PSA that says "don't use p95 with haswell"

That was wrong the clock wasnt applied, its reaching 70°C now. I use P95 for 10min when I first apply a OC and if it survives 10min I go to IETU and run stress tests in it.

Why not use P95?

Why not use P95?

it's been shown to give odd voltage and temp problems

Which is why it's used to reflow EKWB's Indigo TIM. Now that makes sense

I guess they must use overclocked Haswell chips as well.

The thing with Indigo Xtreme is you have to put it between your CPU and the heatsink and melt it before letting it slowly cool and then using the fan/liquid cooling as normal. Video tutorials always show Prime95, and I wasn't sure why it was so popular or if there was a method to the madness of that torture test.

I wouldn't expect them to know or care about the P95 issue with Haswell if they bothered to test it with any of those chips.

You can look around because the information is plentiful, I'm not exactly sure why Haswell doesn't work well with Prime, but it's been decently documented and not recommended.

 

prime isn't really that good anymore, it's the lazy and archaic program, there are much better synthetic tests now.

Such as? I know cinebench is popular as a benchmark, but when testing stability/doing torture tests, what would you recommend?

Any of OCCT/IBT (LINPACK), Aida64

 

of course these are still prone to failure, but better than prime.
