I need some advice!I have been reading alot about FSX and setups, but one thing I just cannot seem to decide on, is the amount of RAM to put in my new computer!6GB RAM should be sufficient under Windows 7 64BIT OS, right? But then again 12GB sounds so much better :( Aaaanyways I read somewhere that WIN 7 64bit supports only 7GB RAM, so isn't the last 5 GB just overkill?Thank you for any light you cast on this subject!Boaz.

I think the following is correct Win 7 Home Basic 64 bit supports max 8GBWin 7 Home Premium 64 bit supports max 16GBI'd get 12GB personally :)

ah ok well that settles it then!I should then also be looking for win7 premium!Boaz.

If you install 6 x 2 GB DIMMs (12GB) instead of 3 x 2GB DIMM, the memory will run considerably slower, as the timings must be relaxed considerably when adding another bank of RAM.Given that FS is a 32-bit program and can only use 4 GB at most no matter what, 12GB will produce no useful benefit unless you are doing something very unique.Lower performance, higher cost, and no useful benefit to FS. Why would you do that?RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO

I often check ram usage while simming and max usage is around 3.5 Gig on my 6gig ram system. That is considering that i have about 8 other applications running alongside fsxFscommanderRc4 PlanG moving mapAI smoothFspassengerExcelASAAcrobat for a/c manuals Its reached 3.5 gig, but never ever 4 gig usage.My advice to you is to save that cash for extra 6gig, and buy the fastest 6gigram you can afford.My current triple channel ddr3 ram speed is 1333-1600, i am planning to get ram that can do 2200 etc. for fsx , When you got 6 gig ram , what you need is faster ram, not more ram.

This is what I am looking at: Corsair XMS3 12GB (6x2GB) DDR3 1600MHzAlso does anyone out there know how to release RAM memory while flying... I want to fly with out crashing so much, until I get my new PC.Boaz.

There hasn't been a need to free up system RAM since the Windows 98 days.You should take Bob's advice. I guarantee you FSX will not run any better with 12GB RAM vs. 6GB, and is likely to run slower for the reasons Bob mentioned.

i still think you better off with 6gig , cause as mentioned fsx only needs 4gig max. 12gig as said will slow down your ram.for freeing up resources while using fsx, earch goggle for a free tool called GameBooster. It closes down all applications that you dont need while gaming, and brings them backup when you done gaming.try to get faste 6gig ram instead of 12gig ram. When you start to OC, you gona need faster ram to keep not more ram.If you have extra cash, save it so you can spend on cpu cooling, the cooler your cpu the more you can oc.

Windows 7 - uses practically all of your physical RAM no matter how much you have - with its Superfetch etcwhilst FSX may not directly use all of the 12GB (probably only about 2GB) - thats no to say you won't still get benefits from 12 vs 6in theory there are ways to make of all of your RAM in FSX - which I learnt on the Arma 2 forums, but haven't tried yet with FSXthere is a program called Linkshell Extension, which allows you to "link" a 2nd directory /area to anotherhaven't tried it for FSX yet - but have for Arma 2 - but I'm a bit limited in only having 6gb RAM. Bascially - you install Linkshell Extension AND a Ramdisk programyou then assign a RAMdisk of whatever size you wishyou then move the files (make a backup first) onto the RAMdisk that you want to run out of memorythen "link" these files to the program directory - the program just thinks its retrieving the files from the normal location, wheras actually its getting them off the RAMdiskin Arma 2 this is quite easy as there is one directory which contains most of the textures (in large files) for scenery, objects etc - in FSX a bit more difficult as lots of small files and lots of directories - but I guess its not impossible - I'm not sure how many directories you can link - and or at what levelin Arma 2 it made a big difference for me - I assigned 3gb as a RAMDISK which allowed me to put 75% of all the object/scenery data onto the RAMdisk.made the game go from jerky (from lots of HDD access), and only ever a max of 1.2 gig of memory used, vs totally smooth, and 1.2gb of memory used + 3gig of memory of the RAMDisk :)re 12 vs 6 - depends on price - ifnot much more and you intend to keep the computer for a good few years - go for 12, if you have to reduce the timings on the memory, it won't make any difference to gaming, it will only make a difference to synthetic benchmarks

Currently I am running FS9 with only 2GB RAM, and at times when I approach an airport in the PMDG 747 it crashes. So I need to somehow free up some RAM before I reach my TOD.ORBX guru John Venema has the same RAMs as I am looking at, and the same amount, 12GBs. He has also got his i7 920 CPU overclocked to 4GHz which is a lot IMO.Boaz.

6GB is still a huge improvement over 2GB.

Sounds like the exception that proves the rule. The vast majority of people that overclock systems with all DIMM slots populated often fail to hit their clockspeed targets, and would achieve even higher clocks with half the RAM. Plenty of i7 users on these forums at well over 4GHz with 6GB, none with 12GB, AFAIK.

There are few people with 12Gb of RAM and 4Ghz clocks over at the overclockers forum in the UK, it's exactly what I am going to do when I get the money together for my next upgrade, I will also be going down the RAM disk route, that's why I want 12Gb in the first place.

Good luck with that.

My experience both in Vista Ultimate x64 and Win7 Ultimate x64 is 12gbs got me rid of OOM errors in FSX. I have GEX, UT, FS Global 2010, REX, and My Traffic X installed and perhaps I

I don't get any OOM's with 4Gb RAM in a 64bit OS and a shed load of add-ons installed and running etc. I want 12Gb to create a RAM disk and put all the textures on the RAM disk so that they load quicker. It bugs me how the textures on AI aircraft take up to 1.5/2 seconds to load if you haven't looked in a certain direction in the last 10 seconds or so, I'm hoping the RAM disk will stop this.Nice to hear you have managed 4Ghz with 12Gb too, I hope I have no problems when I get around to it.
