3930K Assassin 2 OC

post #1 of 25
Thread Starter 
Hello everybody, this is my first post so be gentle. It seems many suggested Sin0822 as the guru around here so I did also ask him for help. I am getting a new system for audio work/mixing so a lot of vst plugins and automation; cpu intensive work on a multi-threaded audio program. I'd like a slight overclock, with the option for calmer cpu when idle. May be OC to 4Ghz, nothing crazy. Is that awesome vid on OC'ing Z77X-UP7 made by Sin0822 applicable for this set up?

CPU: 3930K
Cooling: CoolIT ECO II-240 Extreme Performance Liquid Cooling System 240MM Radiator &
OS HD: 120 GB SAMSUNG 840 Series SATA-III 6.0Gb/s SSD - 530MB/s Read & 130MB/s
MEM: 16GB (4GBx4) DDR3/1600MHz Quad Ch Kingston HyperX
MOBO: GIGABYTE X79 G1 Assassin 2
Windows 8 Pro 64-bit

Is there anything else I should be aware of or a guide for my particular set up in doing this?

I know nothing about OC'ing, just an audio guy so I am very grateful for any help!

Have you already got that machine or?

I mean for such a modest overclock you'd probably not even need to change your vcore from stock, i'd probably just set your Vcore to 1.2 and up your multiplier to 40.

You wouldn't need a whole lot of tweaking at all to be honest.

Hello Comps, thank you for the reply

I haven't but my builder is waiting for me to pull the trigger on it that's why my urgency.
But that's exactly it, I don't want anything too crazy where I have to tweak many things. I think even at stock
the 3930K is a contender! So, I was just hoping for a bit of a boost to get some more out of it.

Please bear with me: you are saying not to change the vcore? I am confused as you followed that with "set it to 1.2" redface.gif sorry
if I misunderstood. An audio computer builder expert mentioned to me to run 3930K's OC'ed at 1.35v and at 1600 for the RAM.
He said anything more and it will lead to instability. Is this wrong or?

Lol nah you don't need 1.35v for that processor, most processors are designed to run on much less than that.

That is wrong i'm afraid what that guy said, i'd probably do the following

http://www.newegg.com/Product/Product.aspx?Item=N82E16820147096 get two of those, newegg are out at the moment

If you decide to get the 3930k which is to be blunt, excessive for audio rendering, that processor at stock speeds and run on around 1.18v and be stable. If you run a 4ghz overclock, which is nothing on those processors, up it to 1.22v and then benchmark it. Each processor is different so you have to treat it accordingly.

What PSU are you getting?

You know, to be fair, he was talking about high OC like 4.5 with a max up to 1.35v. I should've been clearer the first time, sorry. (He is a top builder)
Funny too, because Samsung was mentioned as one of the best components. However, this is going to be pre-built and unfortunately there is no option for the samsungs. Do you foresee an issue with the Kingstons? The PSu is: 850W Thermaltake Smart Series SP-850M 80 Plus Bronze

Get rid of that PSU, it's crap

Can you get this http://www.newegg.com/Product/Product.aspx?Item=N82E16817182133

The rosewill is much better and cheaper and unless you're going with Xfire or SLi then you don't need 850w. Hell to be honest you don't need 850w if you are doing SLi or xfire... 750w is ample for 90% of machines out there.

Nothing wrong with using that memory, why aren't you building this yourself? It's not hard and i'm sure you'll end up with a better, cheaper machine in the long run.


EDIT - Who is building this machine for you?

I was looking at cyberpower......*cowers* please don't flame me too bad redface.gif

No but in all honesty I have had no issues in the past and have ordered 3 pc's from them in the past. I've just never ordered one with the OC option. But that is why I was wondering
if I could OC it myself. But that is the unfortunate part, I don't have that much flexibility with parts. That PSU was the next lowest cost from the stock one. I wish I could build it myself
but there is just not enough time nor am I 100% confident about it. I built a core 2 duo in the past and it wasn't bad but not the best either and it was a headache to get it all working right.

Well mate, tbh you're gonna pay through the nose for something you could set aside a day to build yourself. You know you can come here and this will also give you the flexibility to get exactly what you want.

That makes me feel worse! haha no but really, I don't think I want to build it this time. Who knows though, if I change my mind, you know I'll be posting here about it.
I changed the PSU to this: Cooler Master Silent Pro M 80 Plus. This is 850w again, but as I mentioned, the flexibility isn't there for wattage in this case. But I've seen good things
said about Cooler Masters.

have a look at that, match it up with the one you were looking at biggrin.gif

That is an epic build though, you could throw in another 7950 easy on that PSU as well, the case I put in just for a costing exercise, you can pick what you want biggrin.gif

EDIT - Just seen your other post, well it's up to you mate, you're not getting the best for your money though frown.gif
