I recently picked up a 5930K & have so far got it to 4.1ghz with some very conservative adjustments (last time I over-clocked it was a 2500k so a little out of the loop).

Currently it's with a AIO cooler & runs at around 55/60c under load - so I believe I've got headroom to push more out of it.

I'm aiming for around 4.5/4.6ghz but a little unsure as to how to go about it, I'm currently using the following.

Intel i7 5930K CPU Processor
Corsair Hydro Series H100i GTX 240mm
HyperX XMP Predator Series 16GB (4x 4GB) 3000MHz
Asus X99 Deluxe Intel LGA 2011 V3

I can use either the over-clocking tool within the ASUS AI APP or the core bios, either which is better (normally I prefer to use the BIOS but open to whichever is better).

Cheers!
 
Normal Bios.

125 strap. XMP.

Digi Power Current Cap 140% LLC level6
Then test 1.25v 4250 and so on with cache at 3250-3500
Cache Volts 1.15-1.2, SA 1.10-1.15 in fully manual mode.

I use Intel XTU for testing or Real bench.

Thanks for the tips mate,

What clock should I start at? for those? - also what kind of increase on the clock?, as my volts atm at 4.1 are a fair bit lower (I'd have to double check once home).

Apologies, a few of those I'm unfamiliar with & will have to find on the bios).

Hmm, seems the 4.5ghz while it passed real bench, did seem to have a hang on windows boot - may not be related but knocked it back down to 4.25ghz.

Any suggestions on what kind of increments are best advised as this level OC to reach 4.5/4.6?

Hang on Windows boot add cache and maybe a touch core. just 1.275 both try. 4.5.

Cheers, I'll try that.

Oddly it worked for a few resets on 1.25 @4.5 & two 15min tests you mentioned. It crashed on windows load (but posted fine on boot).

Volts on the cache or up the frequency of the cache (to say 3750mhz-3500mhz). or 1.275v to cache & core?. Apologies if stupid question, as cache volts much lower atm (Cache Volts 1.15)!

Seems to be working @4.5 at a nice temp.

1.275v on the core & 1.2v on the cache.

All I need to do is keep an eye on the temps, I've just thought - if the Corsair Hydro Series H100i GTX 240mm cooler isn't on the right way around, will this mess with temps or is it the same on all sides?.

Also, is there any way to tell if this is the case?.

Many thanks for the overclocking tips, this is a nice speed to run at for daily.
 
You'll have to soak test cache settings. If you want to make sure cache is stable, run AIDA64 and isolate the cache stress test. Run for 2 hours. This is normally enough time for it to fall over. Great for testing cache stability.

Lack of VCINN can also contribute to boot hangs

Managed to get it to this so far, will have to check stability as doing some GPU OC'ing also - done a few tests & benchmarks on just the CPU & it's fine - temps so far are in the low 70's during high stress - gaming in the 50's.
 
Had a few blue dot crashes + lockups on a couple of games - I'm guessing there is very little chance of this being CPU related. Have done a full driver sweep & pulled down GPU clocks a touch & not seen once since, I guess testing is the only way to be certain (GPU benchmarks are a waste of time for stability, witcher 3 4k is the real test lol)

Hmm, would you say from the temps/volts I've got much room to potentially push this much further?. Thanks for the advice btw, it's amazing to have one of the top over-clockers around to get tips from, excellent bonus of being part of this community.

/tips hat.
 
Hi 8 Pack,

Any tips on how to push the chip to 4.75, I've now got it in a custom loop so my temps are much lower.

What are the safe 24/7 volts for each component I shouldn't push past which I'd need to adjust from the above.

Atm my settings are at

Clock
4.5ghz Core.
26 Cache ratio.
125 BLCK Ratio

Power
1.28 Core @
LLC Level 6
+140% CPU power
1.2 Cache voltage
1.1 SA Voltage
1.9 Input voltage
 
For more performance raise Cache multi first. Try for like 4g cache then try again with Core.

No strict rule on whats safe and not safe as each chip is different. I tend not to go more than 1.325v loaded for 24/7 with systems.

Okey doke, so pop the cache multiplier to 32 & try upping the core clock by another one increment.

As my core is at 1.28 at the moment I'll pop it up to 1.29/1.3 & see if I can get to a comfortable 4.625.

What kind of performance benefit does Cache multi clocking provide?, thanks.
