Pretty Boxes
More pretty boxes (980 and a 970, I plan to crossfire them)
On the makeshift bench
All built up
Up and Running

All benchmark/clocks are all overclocked 100% prime95/OCCT/AIDA64/Realbench stable and fit for daily use imo.

My currently testing:

Just for reference, my chip can easily do 4.5 on 1.3 volts. And 8pack said the current batch at OCuk can do the same consistently. It's just the case of increasing the CPU multiplier to 45 and Vcore to 1.3v, and RAM Speed. I can find the exact name asus bios calls it if you wish (different manufactured of bios sometimes have different wordings for the same thing), some thing like 'manual voltage overide'.

Aim higher than 3.9ghz m8, that is just the turbo clock of a stock chip (for one of the cores), doing the over clock of 3.9 is effectively not an overclock :)

I have mine at 1.37 volts for only 100mhz extra because I wanted the same everyday clock as my previous chip. I would feel slightly hollow if it did not match that.

4.7 was stable but temps were not to my liking, I am using quiet air cooling, so ymmv. To the limit it was benchable @4.8, no where near stable.

My pc is looping 3dmark firestrike extreme while I am at work now, if it is not in flames when I come back 8 hours after, I might just settle for 4.6 (200x23).

much smaller process but 0.1v more for the same clock? O.0

Temps seem toasty as well. Is it just a poor lithography process then?

Pretty sure my 2500k screen is under c-state, it needed 1.32 to be stable.

Probably should load calibrate at some point too, I input 1.35V in bios. And the temp are fine, prime95 (yes I know...) highest core temp. Admittingly in open bench environment.


It's just one sample, the important thing is the accumulation of generation improvement from 2nd gen to 6th gen.

Although gaming is minimal but there are some people that like numbers.
 
You sound like you know your stuff but that sounds alien to me! Blame my newness to it all lol.

So what you are saying is, I can get it to 4.5 with a few simple tweaks in my bios with little to no risk or hassle? Sounds good!

Yeah, sorry for wall of text :D

Not really minimal settings and definitely not risk/hassle free. No one can really promise you that except retailers that sell overclocked bundles.

You will be in and out of your bios a lot and don't be afraid if it does not boot.
 
Wouldn't bother with Prime on this platform at all. Can be stable for hours and fail Handbrake in literally seconds. AIDA and Realbench mixed in with HCI memtest pro for memory stability.


Just firing up testing 4.6 / 4.3 uncore at 1.4v

yeah, i know... read a lot of post of people ditching prime95 nowadays.

Its just 4.7 / 4.4 uncore @ 1.34V is AIDA64/realbench stable, but errors Prime95 instantly.

4.6 / 4.4 uncore @ 1.34V is 4 hour prime stable. High 80s on hottest core, no throttling.

If I was not so stubborn about getting prime stable, can probably push further...

Any ways nice to not be the only 6600K in the village.
 
I find my memory is very picky with multipliers. 3000mhz is only achievable with nice and even BCLK such as 100, 200 etc.

They are at 1.35V, non XMP. Stock is only 2666 @1.2V

they do look good :), would match perfect with ROG stuff. But I'm not really a case window type of guy.

My Corsair DDR4 are not very impressive, can only get 3000 Mhz, 2T. 16-16-16-36-1T is AIDA stable but does not always boot :(

The article about Skylake having a good memory controller did not come out when I ordered, would have bought better RAM if I had known.
 
I just decided to have a play with my 6600K, set vcore to 1.3 and multi to 45, ram was already at 3000. It ran 10 passes of intel burn test easy enough, hottest core reached 60 C, coolest core was only 53 so I have large variance.

I left speedstep and everything on, will this be ok? To be honest I don't game so the only work it will do will be un-raring some large files. My idle temps are a nice 26-27 C and my fans spinning at 600 rpm so totally silent.

leaving speedstep on is fine, I always leave it on for extra powersaving and less heat. I have 3x Noctua Fans, spinning @400 rpm :D

Idle temps don't mean much as CPU is only 800Mhz (with a 100 Bclk) when stepped down. But your load temps are very good indeed.
 
I personally only buy sealed retail CPUs to play my own silicon lottery. I buy a lot of used stuff but never a CPU. But that is just me...
