That RAM run dual channel rather than quad @Rob Ainscough? Unforunately my 7900X will only get to 4.7GHz stable. Still, that's better than 4.3GHz that my 6850K could do!! Incidentally, what temps are you getting with your custom loop? My CPU uses 1.27v for 4.7GHz and, with HT on under RealBench, it reaches 94C at its hottest point. That's with a custom loop also.

What frequency did you manage to get your 7900X to Rob? Mine gets to 4.6GHz easily but temps push 85 under RealBench Stress Tests. So I've left it there.

Steve - asked in the other thread but you may have missed it. What do you recommend for my i9 7900X? HT on or off and what AM please? Thanks in advance!

What's performance like with this in v4 please?

Hi all, Well a slight disaster struck - one of my two GTX 1080 Ti's was faulty. Caused a hell of a lot of head-scratching between myself, Gigabyte and NVIDIA. It's only a subtle fault but, after several drain and refill sessions of my water-cooling loop, I was able to narrow the problem down to the card. And, because I removed the stock cooler and fitted a waterblock, no warranty! Brilliant. So my system is now a single 1080Ti. Not the end of the World but a bit of a bitter taste that such a lot of money has gone down the drain. I'm going to see if I can RMA it to the supplier as it's within 30 days. Will refit the stock cooler and hope for the best. At least this means I can finally get on with setting up the PC and getting the all-important P3D installed! @SteveW You may be sick of talking about HT and Affinity Masks now but, with a deca-core, what do you recommend as the best AM with HT turned on? Regards, Ady

Delidding has been proven to knock a good chunk of heat off these new chips - but you void your warranty and I certainly wasn't ready to do that on such an expensive chip. Everything is with HT on at the moment. Once I get P3D installed, I'll do some experimentation and see if it likes HT on or off. If I turn it off, I'll almost certainly be able to get more out of the OC.

With my motherboard, all advice seems to be to leave vCore in Auto. I've only tried 4.3 GHz at the moment. I might try for 4.4GHz and, if it passes the stability tests, leave it there for now.

At 4.3GHz it's around 1.15v.

In P3D? Not tried yet. Got an ongoing issue around SLI at the moment so I've not even got it installed yet. Hope to get it up and running this evening so will report back. I expect to do some proper testing at the weekend. Ady

Hi all, I too saw the videos about the poor VRM heat dissipation - but they were all conducted on fairly low-end motherboards. My Gaming 9 board is top of the line and comes with 2 x 4 pin CPU power ports. Today I overclocked to 4.3GHz - which is what I was running before on my 6850K - and ran a 15 minutes ASUS ROG stress-test. The VRM didn't get above 75 and the CPU hovered around 60 degrees. This was with a very hot and humid ambient temperate of 30 degrees in my office. So it seems that the higher end boards are perfectly fine. I'll push the overclock up by 100 MHz at a time and see I get to. But, to be honest, if I can get the same overclock I had before, but with 4 extra cores, I'm happy. I know a 7700K can go to 5GHz but my 6850K at 4.3 used to perform just a well based on the smoothness I was getting with lots of add-ons. Cheers, Ady

Well - I finally got the new GPU waterblock and managed to get the loop filled without any *initial* leaks. Continued leak testing continues whilst I do my day job - then onto getting things installed this evening.

Absolutely agree. It's not even rocket science....such a simple and obvious thing yet, despite several prods to that effect, Rex *still* remain silent. Beggars belief.

Wow that looks amazing! I'm learning to fly one of these at the moment - and it'd be great to be able to practice procedures in the simulator. Will this be P3D v4 compatible from launch?

It's entirely possible that this left banking is due to left-turning tendencies that you're potentially not aware of and compensating for properly. Have a read of this and see if it helps: http://www.flightsimbooks.com/flightsimhandbook/CHAPTER_02_18_Left_Turning_Tendencies.php

I actually ended up going for a Corsair AX1200i as the EVGA one was out of stock for a few weeks.

So I went and bought the system. I put it together over the past couple of days and, alas, there was a leaky water-cooling component on the graphics card SLI bridge. New part arrives on Tuesday so I should have some P3D v4 results by the weekend. Stay tuned.

Uh huh - and 4.5GHz is a very respectable overclock with 10 cores and 20 threads. And, to be fair, if you buy one of these chips, you've paid for an expensive motherboard too and probably an expensive custom loop for cooling.

Hi ya. The i9 7900X is not a low frequency chip - it can easily be overclocked to around 4.7GHz or more depending on motherboard and cooling. Lots of reviews available - have a Google.

Hi Steve, Indeed - looking to use a 1600 watt EVGA P2 PSU. Expensive but will be worth it for the headroom and efficiency of delivery. I have a 6850K at the moment and this new 7900X will clock higher than it and have an additional 4 cores. Should be amazing! Ady

Thanks for your views everyone - much appreciated. Sounds like it might be overkill for now but that's the point, so that it keeps up with advancements of the new 64-bit platform. I expect this PC to last a good few years and keep up with everything I throw at it.

Thanks Garrett. What made me select the 7900X is that it's the equivalent to what Rob A has at the moment and P3D appears to take good advantage of it. Also, I'm led to believe that some example 7900X's have managed around 4.7GHz with no difficulty (across all cores) when nicely watercooled.

Hi Drumcode, Thanks for your view. I thought, with the latest nVidia drivers and P3D v4, that SLI was fully compatible and did make a difference with heavy anti-aliasing. I have a 1440p widescreen so 8x SSAA is needed to smooth things out. Cheers, Ady

Hi everyone, Was unsure whether to put this thread here or under Hardware - it's specifically a question about P3D so I guess here will do! With the imminent launch of Intel's new X299 platform, I'm contemplating building an overkill rig for P3D v4 that will see me into the future with something that should stand the test of time. I'd very much appreciate opinions on whether this is likely to have much of an impact on P3D v4, whether my selections appear to be compatible and what I might do away with, in the interests of saving money, if it will have little effect. Gigabyte AORUS X299 Gaming 9 Motherboard Intel Core i9 7900X CPU 10/20 (will be overclocked to around 4.6GHz) watercooled 32GB (4x8GB) Corsair Vengeance DDR4 RGB PC4-24000 (3000MHz) 1TB Samsung 960 Evo M.2 PCIe NVMe SSD 2 x Asus GeForce GTX 1080 Ti Founders Edition 11GB SLI watercooled Grateful for your help. Thanks, Ady

Difference between 60Hz and 59Hz? It's about 1Hz Sorry - now that's out of the way (couldn't help myself) let's talk about the actual question you asked. From Microsoft: In P3D terms, I would expect it to have very little effect. V-Sync will be limited by a single FPS, that's all.

Yes.
