I've only ever had one faulty Asus board. Was tricky to diagnose. I swapped it for a lower spec board in the end.

 

I do wonder if it's wiser in terms of reliability to opt for lower spec boards. Seems to me it's the complex, highly featured boards with more to go wrong that give trouble.

Initial testing results : CPU @ 5.0 Ghz at 1.45 Vcore and RAM @ 3255 CL 15-15-17-35 (OC).

 

Stable this far but will probably reduce overclock by a bit since temps are on the high side. The core running the main thread peaked at 90C.

 

Loaded up the 777 at KJFK (default with FTX Global), increased all terrain sliders to max and scenery to max for complexity and very dense on both vegetation and buildings. Water increased to high from medium. Traffic increased to 30% airline.

 

Did a take off and short flight around the airport.

 

FPS hasn't dropped below 23. Results seem good so far.

 

Will update more after fine tuning overclock and playing around with P3D more.

5 GHz is fantastic! Not many achieve that, even at 1.45 Volts. And RAM at 3255 is excellent too, many boards can't achieve that.

 

Even if you have to back it off a bit, it's still an excellent result.

During a stress test I presume?

Aida 64. I imagine it'll be hitting the tj max easily in prime95.

 

I'm gonna aim for about 80-85c max in Aida64 and I'm done. I might be able to pull of 4.85ghz at most I think. Nothing much else can be done without delidding I guess.

 

Good thing is I also managed to tighten the ram timings from Cas 16 to Cas 15 and I think P3D will benefit from that.

Down to 4.8ghz at 1.32v and I think I will stay here at least for the time being. Memory now at 3300mhz Cas 15.

 

Unfortunately any higher and temps are a little too high for me. Maybe when the thermal paste cures better and temps go down a little I might try 4.9.

 

Can't wait to start flying again and see how it fares.

4.8ghz at 1.32v is a great result. Typically voltages are a lot higher than that at 4.8, well over 1.4 usually.

 

You have a nice CPU. I wouldn't bother with 4.9, the extra 100 MHz will make so little difference you won't notice it.

 

​Hope I do as well.

For some reason in P3D the temps are higher than Aida64 and cinebench. But performance wise it's quite amazing. There was some stutter in the clouds but I think that was because I had MFAA on. For the first time in Flytampa LOWW and the aero soft Airbus I'm getting above 30 fps constantly. And at higher settings too.

 

I think P3D might be actually benefitting from the new IPC a lot more than other games and apps. I won't be surprised if even clock for clock performance is better.

 

Anyway you should explore into the bios settings as much as possible for the best overclock at reduced voltages. There is quite a difference in the end result.

I'm about half way through a bedroom refurb at the moment, so will be another couple of weeks till I build my Skylake rig.

 

My intention is to give 5 way optimisation a bash and see what it can do. I'll set it to the extended stress tests, not the minimal 15 seconds per test, which apparently is okay fro 80% of systems. I'll also enable AVX, and probabaly just TPU1, so just a multiplier overclock. Will be interesting to see the results.

 

If that isn't to my liking, I'll revert to my previous method of overclocking within the UEFI.

 

You have a custom loop I recall which no doubt assisted you re temps. I'll be using an NH-D15S. 

I tried the 5 way optimization and TPU and I gathered they're mostly for people who just want to get a little extra out of their systems. Not really a thing if you're pushing for the best overclock.

 

The voltages are set much higher than needed to ensure stability with those methods.

 

Either my custom loops waterblock is really in need of a change or the CPU needs delidding as my temps are no where near impressive.

 

The chip itself is good, but temps are limiting me quite a bit.

 

Also a new issue has arised. My p3d keeps ctd-ing. Not sure if it's a stability thing or something else but the system is stable in everything else though.

My thoughts and experience exactly

Seems like the CTDs were due to the settings changes. Recompiled the shaders and all seems good.

 

 

So anyway, I guess I should leave a bit of advice for anyone else considering an upgrade from Haswell or Sandy Bridge to Skylake.

 

Clock for clock performance seems to be marginally better, however if you can get at least a 500mhz upgrade in core clock itself I think the difference is substantial. Also the gain in speeds from DDR4 seem to help quite a bit too.

 

The new IPCs in Skylake also seem to make a difference, as when I tested the 6700k at its stock speeds performance was still slightly better (~5-10%) at the same settings as I had with the 4770k. 

 

The main benefits come from the increased core clocks achievable over the Haswell processors.

 

If you're stuck with a chip that can only go up to 4.1-4.2 ghz then maybe an upgrade would be beneficial for you. This is purely my opinion.

Actually no, I think you may be getting mixed up with the two different aspects of TPU.

 

TPU 1 and 2 is associated with the "ittle extra" you mentioned, in respect of the TPU switch on the motherboard, but can also be activated within AI Suite. This is, as you say, a quick, mild overclock, TPU 1 equates to 4.4 and TPU 2 equates to 4.6 GHz. This is not a system specific overclock therefore will over volt for some systems. However, not to a level that's a concern.

 

Confusingly, TPU 1 asnd 2 is also an option within 5 way optimization. Here, TPU 1 overclocks just the multiplier, whereas TPU 2 overclocks both multiplier and BCLK. 5 way optimization is not at all intended for mild overclocks, on the contrary, 5 way optimization will take your overclock as far as is possible, while taking into considerations all aspects of your system. 

 

4.8 GHz for the 6700K is commonplace with 5 way optimization. As for voltages, they do seem to be slightly higher than many settle for with manual overclocking. However... Asus have spent considerable time testing literally thousands of CPU's. Therefore I feel they may well have a better understanding of voltage requirements. It may well be that the slightly extra voltage is advantageous in the long term, in terms of stability.

 

The other important point of course is that if you run 5 way optimization and you are an overclocking enthusiast that feels like tweaking further, you absolutely can. If you want to tweak the voltage lower, by all means you can. It's a great starting point, saving time and effort, in addition to providing a safe, stable overclock.

 

I'm finding this quite a lot, I must admit. Many seem to be giving 5 way optimization just a cursory glance, a quick bash, while not understanding fully what it's for and what it can do. The following assessment of it's capabilities is then underestimated.

I agree , but 500mhz is not relevant you get a bad Haswell and quite good Skylake.

The difference is more like approx 100mhz to 4790k and 300mhz to 4770k.

 

Have a very good 4770k 5ghz at 1.32v get a little hot when run Aïda64 FPU test with HT on but disable HT 5.1 1.36v and 90c in aida FPU.

 

My last 6700k is a really good one but the difference is 100mhz not more

I agree it's quite useful. But on my system it would not go past 4.6 no matter what.

 

And I personally feel that as a experienced overclocker the bios seems much easier for me to access and change settings if I need to. The Ai Suite is good, but intended at a more mainstream audience getting into overclocking IMO. After trying it out I still feel the bios is a better and easier option for me.

 

It's a good starting point yes, but not when you still have to spend time fine tuning it afterwards whereas in the bios I can do everything I want to at one go. Asus has also made the bios much more user friendly and accessible. All the overclock specific settings are in one page. The AI Suite however, seems quite messy to me if you are looking for specific settings to tweak.

Sorry but I don't really understand what you mean.

 

I've not owned a 4790k which is why I mentioned Haswell and earlier. It's probably really pointless to upgrade from a Haswell E to a Skylake CPU even for P3D.

 

But I see a noticeable difference from the 4770k to the 6700k in my experience at least.

 

And I'm pretty sure a 500 MHz difference in core clocks is very relevant, especially in p3d/fsx.

1150 4770k and 4790k is Haswell ?

4770k -6700k 500mhz difference ?????

Iam an very experianced overclocker to , no what iam doing.

Here is a 5way with my worst 6700k have 2 better CPUs
