Hello, I am currently running 4 GB of Mushkin Redline @ 6-8-6-24 1600. Would there be much benefit to going to 8GB (2X4GB) of Mushkin Redline 7-9-8-24 1600?

I am not an expert on this so can only offer my opinion. We know FSX is a 32 bit game and can run up to 4GB of Virtual Memory. At the same time you have other programs running, Windows, TrackIR?, FSInn, Weather, etc. If you have lots of scenery and are pushing the 4GB limit and at the same time have all of those other programs taking up a gig of memory then you will get and out of memory error or if not you will require swaps to the hard drive slowing things down. The 8GB of ram will allow all of these programs to run on your ram.Mark.

Not sure you will ever notice it but you will sleep better not wondering about it. From a bench mark perspective 7 9 8 24 may or may not measure worse than you have now. Personally (that means me) I do not like having all my slots filled and would not run 4x1GB sticks. Then again I wouldn't run 1.65v sticks (ya I know it is me against the world).

MarkUnfortunately this is not strictly correct. The Virtual Address Space of 4GB is mainly independent of the Physical Ram and if the VAS is exceeded usually only FSX will crash, but if Physical RAM is exhausted, (as you quite correctly point out), the system will slow down because the system is now probably using the paging file and eventually the whole system will crash (not just FSX) and you may well see the dreaded BSOD. Increasing the Physical RAM on a properly tuned system will NOT affect OOM errors in FSX or cause it to run faster due to non-use/less-use of the paging file. To the OP I doubt that adding another 4GB will do much to improve FSX but adding faster RAM balanced with the system/cpu/video card may show some benefit.RegardsPeterH

Thanks for the clarification.Mark.

Thanks for your responses. Peter, do you have any recommendations for the best ram to get?

mwilkNickN over on the simforums always recommends "Mushkin" RAM and your present RAM looks very good. After thinking about the question I feel that even inserting 4/8GB RAM with a lower CAS Latency I doubt that you would see FSX run significantly better. As I say NickN talks about a balanced system and not knowing your system specs it is difficult to give good advice. If you are running a "SandyBridge" system I think that 1600Hz RAM fits it well.BTW I have 8GG DDR3 RAM installed (G Skill) because I run Photoshop CS5 64 on the same machine and that works quite well - I haven't really seen any performance benefit wrt FSX.RegardsPeterH

Thanks Peter. This is memory that I used with my I7-930 system. It,of course, was triple channel.
