Spireite82 Posted March 3, 2011 Share Posted March 3, 2011 Some people may know that the FM series likes to chomp on our PC's virtual memory and in some extreme cases can cause the 'Running Low on Virtual Memory' problem. Bummer! Even though i have never had this problem I always change page file size as it can boost the games performance whatever your PC specs are:- To do this is simple. 1)On Win 7/Vista go to Start>Control Panel>System 2)Click on 'Advanced System Settings' 3)Click on 'Advanced' Tab 4)Under Performance, click on 'Settings' buttons 5)Click on 'Advanced' Tab 6)Under Virtual Memory, click on 'Change' button 7)Now click on 'Custom Size' 8)In 'Initial Size (mb)' field input x1.5 the size of your RAM in Mb (eg I run 4gb of RAM so this multiplied by 1.5 is around 6500mb give or take) 9)n 'Maximum Size' field input x2.5 the size of your RAM in Mb (eg I run 4gb of RAM so this multiplied by 2.5 is around 13000mb give or take) 10) Click on 'Set' button. You may get a pop up that you need to restart your system. Click 'Restart Now' then you're done! I recommend doing this even if you have never had any problems with low virtual memory as not only does it stop your HD labouring so hard, it can boost your PC's every day performance. Hell. even Microsoft reccommend you do it! Anyway i hope this helps some people and thanks for reading Link to post Share on other sites More sharing options...

PGB_SPURS_FM09 Posted March 3, 2011 Share Posted March 3, 2011 HOT TIP: To stop your CPU from constantly changing the paging file, set the initial and maximum size to the same value. For example, 500 and 500. The value should be at least 1.5 times more than your physical RAM. If your computer has 512MB of RAM increase the virtual memory paging file to 1.5*512= 768 Source: http://www.delete-computer-history.com/increase-virtual-memory.html Link to post Share on other sites More sharing options...

mackemforever Posted March 3, 2011 Share Posted March 3, 2011 terrible maths. 4gb x1.5 = 6000mb and 4gb x2.5 = 10000mb. Terrible maths. Its actually 6144mb because 1gb of RAM isn't 1000mb, its 1024mb. So, you're both wrong. Link to post Share on other sites More sharing options...
Ruudfood Posted March 3, 2011 Share Posted March 3, 2011 The recommendation is also that if you have a 2nd (3rd, 4th or 5th) physical drive that the pagefile should be moved off of the system drive (the one on which Windows is installed) to prevent contention with the OS and thus improve performance.

isuckatfm Posted March 3, 2011 Share Posted March 3, 2011 http://blogs.technet.com/b/markrussinovich/archive/2008/11/17/3155406.aspx Basically if your Peak Commit charge when running FM (and whatever else you run at the same time) is less than Physical Memory, increasing Virtual Memory has little to no effect and any difference you see is all in your head. So changing the pagefile does not boost game performance regardless of PC specs, the two are intimately related and tied to the 'FM process load'.

What's even more terrible math is that you're all horribly wrong, mb and gb = megabit and gigabit, it has to be a capital B to represent byte at the very least (should also be a capital M regardless) theres no 1 gigabit RAM sticks out there as far as I know (anymore would have been 128MB), although perhaps someone is waiting in the wings to pull me up too Link to post Share on other sites More sharing options...
Lazaru5 Posted March 3, 2011 Share Posted March 3, 2011 yeah, as you're all wrong I'll pull you all up Hard Drive manufacturers sell their devices in Gigabytes, however instead of 1 Gigabyte = 1024 megabytes (like it should) they actually say that 1gb is 1000mb. That is why, when you buy that 1Terabyte hdd, you don't have a formatted size of 1024gb but more likely you have a formatted size of around 950gb or so (the drive capacity is actually 1,000,000mb not 1,024,000 mb ) The swap file works better if it is a constant size. It will be less fragmented (if at all) and it will use the same sectors on your hard-drive. There is no need to have a swap-file of 13gb if you have 4gb of ram, an 8gb swap file would suffice. theres no 1 gigabit RAM sticks out there as far as I know no, you can actually buy TWO gigabyte ram "sticks" now... put four of them in and you have 8gb of ram btw, megabyte not megabit, gigabyte not gigabit, terabyte not terabit (the *byte is 8 times greater than the *bit) Link to post Share on other sites More sharing options...

x42bn6 Posted March 3, 2011 Share Posted March 3, 2011 To be honest if you run out of virtual memory with 4 GB of RAM, you are clearly doing something wrong... Another way is to stick your page file on a partition of your hard drive with nothing on it - this way it never gets fragmented and performance improves. So if you have an 80 GB hard drive C:\, you can partition it into 76 GB C:\ and 4 GB E:\ and set your page file to the full 4 GB E:\ drive. I would imagine SSDs are prime candidates for this but remember that SSDs have limited numbers of writes - using it as a pure page file can seriously hurt it over several years.

Aytumious Posted March 3, 2011 Share Posted March 3, 2011 It really depends on your operating system and how you generally use your PC. Most users should just let windows handle it. If you have less than 1 GB of memory in your computer, I could see the need to play with this setting. If you have 1+ GB of memory, just let windows deal with it. Any gains with this type of tweaking are extremely negligible (to the point of being unnoticeable). Link to post Share on other sites More sharing options...

DeadPanda Posted March 3, 2011 Share Posted March 3, 2011 I love binary. But in regards to if you should have followed the advice, it is widely recognised that increasing the amounts does actually help in boosting such performance. PS; In a single GB, there is 1,073,740,000 bytes. Or, 8,589,920,000 bits. Link to post Share on other sites More sharing options...
x42bn6 Posted March 3, 2011 Share Posted March 3, 2011 I love binary. But in regards to if you should have followed the advice, it is widely recognised that increasing the amounts does actually help in boosting such performance. It sort of depends... The more dependent you become on paging, the slower your system becomes, because more and more of your memory usage is getting swapped to disk. The flip-side is that you get more stability because you can exceed the amount of RAM on your machine. So it is a bit like putting a nitrous engine in your little Golf GTI - yes, it will allow your little car to achieve silly speeds, but it is probably going to damage the car in the long-run. The question is whether it is a good idea to put a nitrous engine (i.e. increase swap size) in your Golf GTI (i.e. your PC) or consider getting a better car (i.e. more RAM). Putting a nitrous engine in your Golf GTI will doubtless allow your Golf GTI to do more, but with seriously diminishing returns, and at some point you will start to damage the car (i.e. thrashing where the processor spends a large amount swapping pages to and from memory because so much is being used on disk). So if that counts as improved "performance", then yes - but virtual memory really shouldn't be used as a performance booster as such. Link to post Share on other sites More sharing options...

Ruudfood Posted March 4, 2011 Share Posted March 4, 2011 PC world standard answer = buy more RAM. And that is a correct answer if you want real performance improvements. While strategies like moving the pagefile, defining multiple pagefiles, setting up partitions specifically for the pagefile to avoid fragmentation, and so on will show slight performance improvements there's nothing to beat good old-fashioned physical memory.

So if you somehow manage to load 8 GB worth of "stuff" into memory, you are clearly doing far too much or there is a dodgy program somewhere.

Also, Virtual Memory doesn't work exactly like your description when i let Windows mange my Pagefile, it onyl allocates 2800mb to use which is below my psyhical memory size. 'Dodgy' programs?

x42bn6 Posted March 4, 2011 Share Posted March 4, 2011 Also, Virtual Memory doesn't work exactly like your description In what way? Virtual memory allows hard disk space to be used for "inactive" pages of RAM, effectively extending the amount of RAM you have on the system, albeit with the caveat that paged space is very slow compared with physical RAM. As a result, it is better for the kernel to "swap" in pages into RAM rather than try and process the page file as if it were RAM. For example, if I minimise Firefox, then Windows may swap Firefox's memory pages into the swap file because it's not "active", giving me more physical RAM to work with for other things. If I open Firefox up again, then it must move those pages back into physical RAM, possibly swapping other things out. (Very crude representation of swapping) Therefore I believe my example is correct except for perhaps the amount - it effectively allows you to load up to 8 GB (assuming a 4 GB page file) into memory, although perhaps you won't want to have all 8 GB "active". when i let Windows mange my Pagefile, it onyl allocates 2800mb to use which is below my psyhical memory size. I don't know why yours is set so low. 1.5 times your RAM is a sensible figure although it depends on what version of Windows you run (Vista and above require more memory for various memory dumps). 'Dodgy' programs? Nope, not on the PC's i've seen. It's not always something visible. Anything that leaks memory - Firefox is a nasty example where it can consume gigabytes with badly-designed plugins and lots of Flash videos. Link to post Share on other sites More sharing options...

I know all about memory leaks, the FM series have suffered with them since the CM's were on the scene and i think it's silly to suggest nobody with 4gb of RAM ever has this problem unless they're running something 'dodgy'. What with all the programs that 'auto-update' these days (itunes, quick time, java, adobe, anti-virus, defender, windows etc) and the amount of RAM Fm can take up it's not impossible for it to get to this amount. Heck i've seen FM using nearly 2gb of my physical RAM before. I believe some of us are getting too technical for some people on here but the bottom line is that if people do get the 'low virtual memory' fault, whatever the spec of their PC, follow the steps and it should rectify the problem.
