Rob,

I filtered for 16Gb (2 x 8Gb) and checking for 4400/18 there were none for that combo. The two 4600 modules were shown as discontinued on G.Skill.

There are no 4266/17 modules for 2x8Gb. That last one you linked to shows as not available in the UK.

Wow... when I last built in Feb of this year my options were limited to 3600 MHz DDR4.  I went with the Corsair and my ASRock mobo clicked it right on with the XMP 2.0 setup.  Very easy.  As with most things in life what looks complicated at first is just a sequence of small steps to gain understanding.

64gb of DDR4 2666Mhz. Bring it. 

Ray, I went through the same exercise a few weeks ago using the formula that Bob Scott provided you. And I came to the same conclusion as Bob. The Gskill 3600 CAS 15 had the lowest latency ( ns per Bob's formula not CAS) for the price. In addition the voltage is only 1.35V so you have a little overclocking headroom. This is the memory that Rob provided a link to. I purchased a pair of 2 x 8gb sticks today from Microcenter in Denver along with an Intel 8086. I saw that they got the 8086s back in stock today so I drove down this morning as I think Bob Scott bought the last one they had earlier in the week. . I was lucky.  Now I just have to decide on a Z390 Motherboard. You can get some higher speed RAM with the same low latency but the price is quite a bit higher and so is the voltage as you will see. 

I used the same analysis when I purchased memory for my current system built in 2013 and have been very happy with the performance of it..

Ted--in case you run into any trouble with that memory, I did have to bump up the DRAM voltage a little bit on the Asus Maximus XI Hero to get it stable at its XMP II settings (3600-15-15-15-35).  It's rated at 1.35v...took 1.365v on my mobo to put an end to the occasional (once every 2-6 hours) memory error.  Memtest 86+ is your friend.  😉

In the next few months I’ll be running a single monitor at 3840*2160. Hence the need for max power from the graphics card.

Not...Necessarily...True. 

Why are you going to be running ONLY 3840 x 2160?  Is your monitor not 4K capable?

I'm running a single GTX1080 (NOT even a ti version) on a 65" Samsung UHD 4K Curved TV through an HDMI cable from the GPU to the TV.  P3Dv4.3 resolution set to 4096 x 2160 in P3D (4K resolution).  That resolution is 4K, so you do NOT need to crank up any of the AA settings that overtax the GPU performance.  If you are going to be using a smaller "monitor" than my 65" TV at 4K, you don't need to be over-spending on the GPU just to get "maximum power".  If your monitor can already display 4K, there won't be any "jaggies".  You wouldn't even need to use an SSAA setting.  Heck, I run 8MSAA, no FXAA, and everything is crystal clear even with the most taxing scenery and complex PMDG aircraft.  Neither my CPU nor the 1080 GPU ever maxes out at 100%.  And I don't use Hyperthreading when running P3D.  P3D does not benefit from it, and all it does is increase the temperatures of your hardware for no good reason while flight simming.  Yeah...I run P3D, LittleNavMap, Navigraph Charts, ActiveSky for P3D, REX SkyForce, Radar Contact, and usually have a Windows 10 browser window open too...all at the same time...all from one computer...with no Hyperthreading.  If anyone doesn't believe me, next time you are in Las Vegas send me a PM and I'll be glad to show you how to do it properly.  No need to even mess with Affinity Mask settings.

Ray, if it was me.....

I wouldn't be paying PREMIUM MONEY (read: Hugely Jacked Up Price) for a 2080Ti GPU right now.  It is total overkill if it is JUST for your P3D simming using a single monitor.  P3D doesn't even use Ray Tracing yet, etc.  Get a "discounted" 1080Ti at most, then put your money into what will REALLY help you now...a 4K monitor if you don't have one (so you CAN use a 4K P3D resolution with no need for SSAA settings).  And then get at least 16gb of the fastest darn memory you can find (I have 32gb, but only because I do video editing too, and the extra 16gb to 32gb then does make a big difference in the speed of the video editing).  If (and when?) P3D ever BECOMES capable of using things like Ray Tracing in the future, if you want to buy a 2080Ti THEN, the price for it will have come down dramatically, and you would already have a 4K monitor that didn't need SSAA settings, along with the fastest memory you bought now.

Will P3D ever use Ray Tracing?  Probably.  Or Maybe. But many people would have thought our flight sim would benefit from SLI by now too.  So there are no guarantees you would ever get "maximum USE" out of the 2080Ti until (IF?) P3D ever requires that kind of GPU.  Use your hard earned money to buy what gives you the most bang for the buck NOW. Not for what MIGHT happen in the future.  If you "need" a 2080Ti in the future, it would only cost you HALF (at most) of what you would pay for one now.

Just my thoughts.  You asked.  🙂

You're missing the 4400/18 (244) - this is what I have for my new build … I think there is a 4600 CL19 1.5v (242) and a Corsair 4700 CL19 (247) … 

These G.Skill F4-4266C17Q-32GTZR look interesting at 4266/17 (250).

The last one you listed looks like a pretty nice price to performance ratio: https://www.newegg.com/Product/Product.aspx?Item=N82E16820232306&Tpk=N82E16820232306

Cheers, Rob.

your 4400 is better binned kit, its a speed hype now ,your 4400c18 as mine 4600c19 kit do 4266mhz 16-17-17-36 with 1.475v that  what i run today it performs better than 4400-4600 with deafault XMP

 

Edit: i run 32gb on X299 and 16gb Z370

Still happily flying with 8 GB RAM, wondering what I am missing

You need your settings more to the right. They are too low.  😁

I’m close to placing an order for a new PC to run P3D v4 and cannot decide if 16Gb of RAM is sufficient or whether I should go for 32Gb for future-proofing.

The best way to find out is to ask you to complete the poll and add any comments here you feel would help me (and potentially others). Thanks for your help.

To this date, I have not even got near 10Gb of usage of my 16Gb,  And I pretty much nearly max my settings, even in heavy rain, clouds and fog.  Using a 65 inch 4K resolution. Getting 32Gb for P3D is honestly a waste of money.

Thanks for that Rick. The monitor I'm buying (note a monitor, not a TV) has a resolution of 3840*2160. That applies to all UHD monitors I've researched. Never seen anything with a 4096*2160 res. That 4K resolution was just at cinemas so I'm surprised your TV can run at such a res.

It won't be anything close to 65". I was thinking of a 40" Samsung TV but the space is too tight so I've decided to stay at 32" and go UHD.

I've seen enough evidence now that 16Gb is fine for P3D and will be looking to get some quality sticks.

I'm now thinking again about the 2080Ti. I posted on Rob's topic a couple of weeks ago about how disappointing the fps were compared to the 1080Ti and for all that money. A card is something that can be changed later on so I'm starting to think about the best overclocked 1080Ti or possibly a 2080 that would have Ray Tracing capability but the 1080Ti is now under serious consideration.

I have a networked PC for LittleNavmap, EFB and Radar Contact. Had that arrangement for years. Food for thought, thanks.

Thanks Ted. That G.Skill memory now looks favourite. The company I'm buying the PC from will be doing the overclocking. I'm too scared to do it!

I’m going for the 2080Ti so 11Gb should be enough.

 

As far as I know, the 20 series isn't that much better than the 1080Ti

Thanks for the link Jude. I have seen that video. All those people can't be wrong. From the results I've seen the 2080 was comparable to the 1080Ti in performance in many games but more expensive.

Been doing more thinking this morning about the card now that the RAM thing is sorted. I asked myself if I should buy the 2080Ti when I could buy the 1080Ti and effectively get the Thrustmaster TPR pedals for nothing AND still have £200 left over. I think I know the answer to that.

If the 2080Ti had another 5-6Gb of VRAM you could perhaps understand the price hike. But when it has the same as the 1080Ti but DDR6 compared to DDR5 it's hard to see why it costs so much more.
