Hello,

So I finally build a new computer this WE to replace my NoteBook ( i7 2630 QM, Acer) because it was almost impossible to work correctly on it professionnally. ( Audio, Mastering, Mixing, Sound Design etc.. It wasn't supporting low buffer, had some crappy click, pops, glitches all the time.)

So I have now a good Work Station, 4770K and Asus Deluxe Z87 with an SSD, which work perfectly, I take a K CPU because I believed that maybe 3.5 would not be enough for what I do but it seems to be pretty good now. ( More than 40 % CPU usage is often equal to problem with Audio in Ableton Live).

I don't think I'll OC it a lot for the moment because it seems to be enough at 3.5-3.9 and I don't have the knowledge to do it properly and securely, and it seems that there are not a lot of people using TPU 1/2 Switch of 4Way Optimization here so if it not stable it's not really interesting to have some problem for advantage that are hard to see in use.

However I notice that if I don't lock the CPU at 100%, Ableton isn't able to tell to the CPU, now I have to work go to 3.5 or 3.9 Ghz and it often stay at 800, which cause problem ( glitch pops cracks etc.)

So I go in the Power Option of Windows and I set the CPU to 100% Minimum and Maximum. So now in AI Suite I see always the CPU between 3.5 and 3.9 Ghz.

I would know if this practice has some disadvantage ? ( a part the fact that it's now locked at 3.5 Ghz and electricity current will be higher)

There is also something that makes me afraid, I saw warnings about Adaptive Mode ( in the reference OC Topic for Intel CPU), telling that I should not make some Synthetic Stress with Adaptive Mode.
The thing that I don't understand is that when I go to the BIOS the Voltage is at 1.024 and when I go in Ai Suite Manual is at 1.000.

So if I set it to Manual into AI Suite, there will be no problem if it's 1.000 instead of 1.024 ?
What I've understand when reading on the web is that anything between 1.000 and 1.250 isn't dangerous in Manual Mode, but I prefer to be sure because I never played with these parameters before so...I don't want to blow anything

Then there is something I don't understand very well, if I want to make a little OC, let's says 4.0 Ghz The only thing I have to change is the Multiplier at 40x instead of 35x right ?

An then run a synthetic stress test and if it's not stable increase the voltage a bit right ?

Do I have to disable Turbo Boost if I OC ?

Is there any other things that must always be in Manual Mode and not in Auto/Adaptive when messing with the Multiplier / CPU Core Voltage ?

Anyone having stable System with 4Way Optimisation / TPU 1 or 2 on Asus Z87 Delux, with low temperature ( I'm at 27°C at 3.5-3.9)?

Those are a lot of questions. That will cost you

The CPU will wear out faster with C1E and speedstep disabled (basically disabling the throttling down). These CPUs are made to be very durable so you won't blow anything or see any noticeable decay. It will be a bit harder on the power bills though.

The voltage difference is called vdroop. After setting the value in the BIOS the VRMs will keep the voltage swing close to the value you entered (for intel this is typically lower, but there are boards that see wild swings upwards -- my MSI P67 GD65 was one). Of greater importance are the swings (how constant the 1.000V is).

You will not be voltage limited with this chip generally so below 1.25V should be safe. The problems would be temperatures under load, since these chips run hot.

As far as overclocking goes. You should enable turbo boost and increase the multiplier. Run 20 passes of linX or Intel burn test and something that stresses over a longer period of time (a large render or running a distributed computing app does the trick for me).

I think 4GHz should be possible at default voltages, but to be honest I have no experience in overclocking haswell. Typically you'd increase in steps of 100MHz (1 multiplier level) and test until it fails. CPUs have a relatively linear curve where they don't need a lot of volts to clock higher but they saturate past a certain clock (this differs per individual chip, basically luck). You would want to find that saturation point and not go further than that. Or even somewhere before that happens if you don't want to increase volts at all.

If you come to Geneva (CH) I can pay you in beer

I think I'll not overclock for the moment because my Audio Project run just fine with the new computer and the CPU set at 100%.

Thanks for you answers ! Have a nice WE !

Yeah, only OC if you need it. There's no point in increasing power usage if you don't need it (I'll probably be banned one day for saying this

)

I've been to Geneva 2 times. Beautiful each time I see it. Also about the only place I can converse with people since I speak French (Lausanne, Neuchatel). Italian and German I can read, but my speech is bad.

No problem at all man, have a nice weekend as well
