Cubase and i7-6900K O.C or not?

I just swich from Mac to Pc, and from Logic 9 to Cubase pro 9. I built a PC with an i7-6900K. I work on huge orchestral templetes. Do you recommend to OverColck (O.C.) this CPU? If so how far should I go for an stable system?
I ask this because the people who are assembling my PC just call me and asked me if I wanted any O.C.

These are my PC specs:
CPU: i7-6900K
MB: Asus deluxe ii
RAM: 4x16 64GB Trident Z 3200 CL14
GPU: GTX 1060 6GB
cooling: Hydro Cooling Corsair H100i v2
Power: Corsair 850w modular platinum
OS drive: Samsung 960 pro M2 512GB

Thanks in advance

While we cannot recommend a specific configuration or guarantee performance in any way, I do recommend you view the following third party video that has some extremely helpful and relevant information.

I heard someone say once that if you have an enthusiast level Intel processor, you’d be doing yourself a disservice not to OC it. These chips are designed to be OCed, and part of the reason you pay a premium for the “K” processors is the ability to OC them. That said, OCing is not for the faint of heart, and would take many hours of research to learn to do correctly. ASUS “Easy OC” etc. is not usually recommended, and the best results are achieved with tweaks to the BIOS by someone who knows what they are doing. My 3930k is running at stock right now, but I would OC it if I had knew what I was doing :laughing:

Thanks to all replies!
I already knew about that video, but thanks, I watched again.

If anyone have his CPU and tried some OC, it would be very helpful to know his/her thoughts. Like how much should be pushed or which value shouldn’t be overpasses.

Google 6900k OC. Gamers are very good overclockers and they also need stability. They always list save and extreme settings. Go with save, but you do need an aftermarket cooler anyway.
I have a few OCed older core2 quads from 2.86 to 3.6ghz (Q9550). This is an easy OC which doesn’t need to may tweaks. These will usually give you an extra 25%. Getting more then that is much more difficult and not worth the trouble and heat IMHO.

i use the 6900k i7 with an asus z170-a board, the board has an inbuilt XMP profile, which matches the clock to the ram or some magic like that, baiscally makes the ram faster and the cpu slightly faster, its been rock solid and zero issues.
try it;)

Thanks to all replies and tips!

With the mobo utilities included with these new systems it is very easy to OC. I originally had mine running close to 4.5Ghz. To be honest, I saw no performance improvement in Cubase so I set it back to 4Ghz.

Again… very easy to do with the bios utilities usually included with the mobo.

Regards. :sunglasses:

And never use the software utilities included by the manufacturer, use the bios.
Those utilities can create audio problems, as they constantly monitor the clock and can adjust it accordingly.
With a K CPU the multiplying is not locked, simply set that to a higher value in the bios and turn off all turbo boost.
That is anything that can automatically adjust the clock speed and voltage of the CPU, you want it to run full throttle all the time.

I work with the same CPU and big orchestral templates. No problems here, without overclocking. The only part which could go a bit faster is loading a project - but even this takes only about three minutes. If you switch a lot between orchestral projects you should probably go for Vienna Ensemble Pro.

Thanks again for taking the time to all of you to help me. I really appreciate it.

Oliver17, thanks for your thoughts. Yes, I use VEP. So is good to know that is working fine to you out of the box.

Two more thing,

  1. The guy from the store (they are not audio pro specialists) told me that I shouldn’t OC a computer I just bought. He advice me to wait one or two months and then if the computer is stable itself, then do it if I want. Do you guys think is a good advice? Sounds fair to me

  2. The guy in the store wants to place my OS drive, a Samsung 960 pro 512GB, in the PCIe slot using an adapter that comes with my motherboard (Asus deluxe ii). He is telling me that this way is much better than placing the M2 drive right into the M2 slot that this motherboard have. Is this correct? Sounds nonsense to me.

I have a Samsung 961 1TB drive for samples. My specs are below. I run huge templates too. Two points from me:

Using CrystalMark I found that my M.2 drive (loaded nito m.2. slot) slowed significantly when I used the Asus EZ overclock utlity - the machine sped up by purpotedly 20% but the drive slowed down! More info here:

A lot of people are having this issue with Samsung SSDs even so, though my SSd runs at about 2/3rds (with overclocked bios) it’s still a lot faster than an SSD.

I have over 1300 instruments loaded into my master template. I folderise, group, disable then hide. I find I can load this template into 4.5 gig of RAM inc windows. I just dont see a need for Vepro if your not running slaves. Vepro introduce a further level of complexity that was not necessary.


The critical bit in the article is the bit which states that you can put the graphic card slots back to Gen 3, but not the M.2 slot. This would make sense in term of what your 'guy in the shop states

I would try it without overclocking and see if it’s fast enough for you. If it aint broke don’t fix it.

Thanks for the reply.
Since I am using second gen X99 bomb, I would like to know if this issue is solved. I am using the Samsung 960 pro, just released, so maybe they fixed it.

I said I use VEP, sorry, the correct answer is that I used to use VEP, but lately it’s true I liked to load every sampler in each track inside the session. The good thing about VEP (using one PC, no slave) is that once you load all the instruments into the RAM, you can switch between projects easily and faster.

1300 instruments on 4.5 GB? U didn’t mean 45GB?

Thanks again!

Thanks for the reply,

Very good point found in that article.
But again, do you know if this issue it may be solved since I am using a second generation X99 board, with new CPU broadWell? And the very new Samsung 960 pro M2?


Answer 1: Yes 4.5 gig - really 1348 tracks all disabled - leaving 27 gig for anything I enable.

Answer 2] The issue is not “solved” but …

As I understand it there is no facility to keep the m.2 slot at gen 3, when overclocking in the current bios. However, there is a possible workaround - put your m.2 in an adapter card - not the mobo slot (then set this to gen 3). I just bought one, I don’t know if it will work for you or others. I await the postie. My board is an X99a usb 3.1. My sequential speed for the samsung 961 with default settings is 3500 (yes really) when the PC is overclocked using the EZ facility it drops to a blistering 1840. A Samsung top of the line conventional SSD (2.5 form factor) only reaches 550.

Here is the link:

I’m running some libs off 1tb evo and ot only gets 250 mb/s. I would prefer an m.2 to host sample libs and have to os on regular ssd.

Load time is dictated by speed and latency of your hard drives, going all SSD is the only way round that - if you’re already all SSD then you’ll have to wait a few decades until Steinberg decide to multithreaded project loading as I believe Cubase loads tracks serially.

Sometimes this debate is perspectives and workflow concepts, with hard facts thrown in.

I have a template with currently 1348 disabled tracks which loads in 9 seconds. Sometimes I use the whole template, but often not. I have cut down versions. If I lack a track from the master I can import it. Alternatively, If I load the template it loads into 4-5 gig of ram disabled - leaving plenty of room. The master is folderized and invisibilised in Cubase - so you see Tabular Rasa.
