Manual 1.380 and when I monitor it during realbench it goes to about 1408 max. Skylake takes more vcore then the others as long as you're under 1.5 you'll be fine.

 

1.5 volts may be a tad high. Both Intel and Asus "estimate" a max of 1.45 for Skylake. To be honest though, I can't argue to strongly, as Intel don't publish an official maximum voltage. No one really kniows how high is too high.

IMO, it ain't much of an upgrade. FSX, and especially P3D are benefitting far more from GPU upgrades than new CPUs. Intel is focusing more on integrated graphics and power saving features of their new chips instead of the types of things that benefit a 10 year old program like FSX (and P3D since most of the underlying code is original). 

 

Don't do it. 

 

That's true, but even if clock for clock performance is the same, P3D seems to benefit quite a bit from higher core clocks and that is mainly what I'm after. Now if I had an average 4770k I would have overclocked it a little higher and probably would have been satisfied with the results. Right now being stuck at 4.2ghz and getting poor performance even with autogen and whatnot turned down is a little frustrating.

 

I have a 970 GTX so it's pointless for me to spend that much money to upgrade to a 980 or 980 TI just for higher AA settings. I guess you already know that the benefits from GPU upgrades you are talking about are solely in relation to the GPU intensive settings (Tessellation, AA, AF, Water, Shadows), which I pretty much already have at the max except for MSAA which is at 4x.

I also can't blame you for wanting to stay far away from de-lidding the CPU. I've never done it. I know that I'll break something.

 

I just purchased a little tool from overclockers.UK to make delidding a painless process. Search Delid Die Mate, worth every penny and I just hit the magic 5ghz mark on my 4790k! Not for the casual simmer, but this method really ups your thermal threshold, and chance of damage is almost 0%. Still void your warranty tho.

I agree. I'm not professional in OC, but do consider my 4.7 with 1.35v is a little bit high for the voltage. My temps are usually hit 71-73 max with H110. Usually stay around 62-65. Perhaps I should try to lower the voltage to 1.33, maybe even 1.32, but since people are saying that my temperatures are fine for I7-6700k, I'm a bit lazy to experiment.

1.35 isn't too bad for 1.7 to be honest.

 

71-73 you say. Was that running a synthetic stress test or normal apps?

Synth tests showed 70C at MAX (RealBench and AIDA64). 73C i saw once in my life with P3D loaded with NGX, UK2000 EGLL, 100% AI, ASN overcast layers. Again, it was one-time spike. Business is usual typically on 58-63 level for running fully loaded P3D. Idle = 33-35 if I'm not mistaken, but I never check idle tempts precisely.

Sounds perfect to me. I hope I achieve 4.7 and 1.35 at those temps. I'll be very happy with that.

I've decided to go on with the upgrade. How is the TIM on the 6700k? Does it need to be delidded as well?

Well...honestly have no idea. As I said, I'm not a professional in this area

Well no, no CPU has ever "needed" to be delidded. You should expect 4.6 - 4.8 GHz in terms of overclock, without delidding, depending on how the silicone lottery smiles on you and of course your cooling. 

 

From what I understand, the TIM situation is pretty much as it was with previous generations. Same results regarding drop in CPU temp when delidded. Some shave 10 degrees off the CPU temp, some manage as much as 20.

 

If you decide to delid, it's back to the razor method. The PCB is now thinner, so risky to use a vice. Also, as "One Who Knocks53" said above... the Delid Die Mate is now available, that makes delidding Skylake a piece of cake. At least it's available here in the UK, not sure about elsewhere.

 

Personally, when I eventually glue my system together in a few weeks, I won't delid. I don't see the point for a few hundred megahertz extra.

That was what I was afraid of. My current cpu is probably one of them with the worst TIMs. I was hoping there wouldn't be that chance of getting a new skylake with the same issue. Only the chips made in this certain country seem to carry this low quality.

Definitely agree with this. Price vs performance gains are negligible as far as I can tell. I'm sticking with my 4770K until it croaks.

Which country? It's no issue if you tell us. If you tell me I can check the validity of the claim. Certain batches overclock better, and yes it's true that certain batches from certain sources may not have a top-notch TIM die interface. These things change though. Might not be the case any more.

 

Are you saying you've had heat issues?

Well I guess there's no harm in saying. It's from Malaysia. Not sure if it's known worldwide but nearly everyone in my country knows this quite well. Fortunately we now also get stock from coasta rica which is said to be much better.

 

Yes my temps reach a Max of 90+C at less than 1.20V and LLC 5. Thankfully though I get 4.2 ghz at 1.19V.

I'm running a 4770k @ 4.2 with a 780gtx 3gig and it's still handling everything great. For me this combination is still fine.
