When it comes to failed RAM I can only recall one incident of bad memory in the last 25 years and that was when I swapped my 8Gb for 16Gb on this PC a year ago. Lucky perhaps.

I just noticed this comment.

I just recently bought two DIMMs 8Gig each matching my other two so that I had 32gig RAM.

The first batch that arrived I couldn't get to be recognized, tried everything, turns out one of the two was defective, never ever happened to me before. NewEgg immediately replaced and took others back no costs. Excellent service but sure was frustrating because I though I was doing something wrong.

Goodness. I have P3D too and even all settings on Max, and under heavy rain, clouds, AI, and high-end add-ons, never come close to 10Gb.  lol   Sooooo, wondering.

I too have sucked back the RAM but I also run several applications at the same time. By moving to 32 gigs both my sims fly silky smooth with max settings. Its a joy. So managed to avoid upgrading the video card for now.

My god, talk about conflicting info totally confusing me as to how I should go. One chap who seems to know what he’s talking about saying he can see 15Gb+ being consumed but other people saying it’s less than 10Gb on their setup.

First scenario. I buy 16Gb and P3D v4 is fine but later on possibly with v5 in a year or so that version needs more than 16Gb. But the memory I bought may not be available any more so I have to dump 2 8Gb sticks and buy 2 16Gb sticks effectively losing the money for the first two because you need matching memory.

Second scenario. I buy 32Gb now and if the next version needs 32 I’m fine. Purchase justified. If it doesn’t need 32Gb then I’ve spent money on a 16Gb stick I didn’t need.

Third scenario. No version of P3D never needs more than 16Gb. Buy 16Gb now and no further expense. Likelihood? Only people who know are L-M and they aren’t saying.

The second scenario is less expensive than the first. Logically it makes sense to buy 32 as the financial hit is less than the first but more than the third.

Maybe I should just toss a coin. 😕

I thought I'd better chime in or you might not be able to get to sleep tonight worrying about this Ray.

As you noticed most people are fine with 16 gb using P3Dv4. Ed, who recommended 32gb, did not state what addons he uses although he does not seem like one to install a Christmas list of addons like some do. He also said he is making changes to P3D that are not in the UI but did not state what they were either. I can only assume that they are config changes. Ed is a developer so who knows what development software he is running with P3D and what their RAM loading is.

I know you are chomping at the bit for the 64 bit version of the Concorde. I suggest that you ask FSLabs what they expect the RAM loading to be from that. I think that aircraft set a record for virtual memory use in the 32 bit version.

I am staying with 16gb for now mainly because I will be able to overclock my system easier with it versus 32 gb. Based on my current system, 8gb RAM 3770k, 16gb should be fine for the few addons and settings I use. Now perhaps a new 8086 system will need more RAM with the same scenarios or more likely I will crank up my settings with a better system, but if that is the case I will know it fairly soon. Perhaps P3Dv5 will require more RAM but I am willing to roll the dice on that. Maybe we can get Rob A. to give us some hints on the RAM needs of P3Dv5.

Hi Ted,

Appreciate your post. I don’t think FSL are that advanced with 64-bit Concorde to make a meaningful estimate. But given the number of sub-panels it would probably be higher consumption than their Airbus.

Whilst Ed was well meaning with his advice it was frustrating he didn’t divulge any details why so much RAM was used. But as a developer he has a good insight into the sim.

I’m having the system built and overclocked professionally so they should have the skills to handle 32Gb over 16Gb. Still two sticks after all.

Going to bed shortly. Don’t worry, I will sleep. Mind is almost made up.

In that case I would put the question to your builder as to any overclock limitations with 32 vs. 16 gb. They should have the direct experience and answer. I, on the other hand, have not built a new system since 2013 and my suggestions are just based on other internet "experts". Looking forward to hearing how your new system works for you.

Ed does know his stuff and I was not inferring the contrary. I was just stating that he left out the details as to why his RAM use was so much higher than others.

I notice folk discussing AA of P3D as if it is simply monitor resolution specific - it's not. AA is performed on the objects inside the scene.

So for example: Transparency mentioned in AA is not to do with bottles and glass, it's to do with the edge pixels as they merge with the background.

Also the 20 is played down a little against the 10's. The 20's have new bearings and also impose less load on the system bus, have some interpolation tricks I think (not sure)  can improve the look of P3D with a simple tweak, maybe not so quick to use the RT mode, but maybe this can be utilised in the near future. Also less load on the system bus with sli - sli users take note this should help alleviate problems with system bus saturation and reducing cores. Memory, 16Gb will do most systems, any worries stick four in. With bigger GPU's the use of RAM can creep up simply because of more intense setup.

If I am not offering details, it is because I can not.  Simple as that.

I bought 32Gb because it seemed a reasonable investment for the future.  Looks like that was a good move 😉

2 x 16gb is no problem only enable XMP as with 2 x 8gb , thats if you dicide to stay below 4000mhz 

Am I reading that right in your signature? Intel Core i7 8700k @ 5.60Ghz?

The builders will take care of that. Memory is 3600.

I hope you can understand my frustration when you say you've used up to 15Gb but cannot provide any evidence.

you read right that was with a customloop, run it on a AIO Fractal 360 now, with at lower vcore 1.45v 5.5ghz HToff mem 4400 c18 for P3D-V4 its stable no ctd or ntdll crash with the FSL A3xx , tested the stability with aida64 6hours and occt.
