How To Determine If More RAM Will Help?
Asus Zenbook - came with only 4 gigs.
Sooner or later, I will have to crack the case to replace the battery and I am thinking maybe that would be the time to kick the memory up to 8 gigs. But how does one determine if more memory will help? I see a *lot* of 80-90% memory usage just running the couple of apps that I run the most (home theater and Chrome). Is it as simple as looking for situations where memory is 100% used? Or is it more subtle? -- Pete Cresswell |

But how does one determine if more memory will help? How much RAM you need for good performance is *not* a one-size-fits-all situation. You get good performance if the amount of RAM you have keeps you from using the page file significantly, and that depends on what apps you run. If you are currently using the page file significantly, more memory will decrease or eliminate that usage, and improve your performance. If you are not using the page file significantly, more memory will do nothing for you. Go to http://billsway.com/notes%5Fpublic/winxp%5Ftweaks/ and download WinXP-2K_Pagefile.zip and monitor your page file usage. That should give you a good idea of whether more memory can help, and if so, how much more. |

If the Commit Charge Peak was larger than Available Memory, the excess is likely sitting on the Page File. In this article, the author of the article uses Process Explorer as a portable way to track Commit. http://blogs.technet.com/b/markrussi...7/3155406.aspx http://blogs.technet.com/blogfiles/m...e_thumb_14.png Process Explorer is available here. https://technet.microsoft.com/en-us/...rnals/bb896653 Try View:System Information. You can leave it running for the day. Windows 8 has a couple of utilities of its own (Task Manager and ResMon), but I don't know if they show that exact counter or not. Paul |

That should give you a good idea of whether more memory can help, and if so, how much more. "Nothing" is a bit of a stretch, more RAM can still help because a modern OS will use it for caching. But the effect will be moderately minimal, whereas obviously pagefile hits cause a very significant performance impact. The slower your drive, and the less frequently you reboot, the more it's worth investing in extra RAM since the penalty of a cache miss is that much higher, whereas if you're using SSD backed storage, cache misses are less costly. Unfortunately monitoring and understanding cache hits and misses is more complicated since you can't easily predict the impact of changing total available memory, whereas pagefile hits can (mostly) be predicted if you add RAM (as long as you don't get silly and disable the pagefile) -- The preceding post may have contained unsuitable materials and should not have been read by small children. |

How To Determine If More RAM Will Help?
Per Wolf K:
If HDD access is close to continuous, max the RAM. In this case, it is almost continuous - even when I am running stuff that is not opening anything from the HDD (which is 99% of the time). Sounds to me like, for the eighty bucks the RAM costs, I should just forget about any complex analysis and put it in. -- Pete Cresswell |

In the 15 years I've been building computers I never once said: "Doggone it, I put too much RAM in that machine." |

snip As I refuse the buy the newest, latest and greatest computers / servers, most of what I buy is one generation old (6 months to 2 years old) and acquired through eBay. This means there will probably be a fair amount of compatible, used ram on eBay and I will frequently get a great deal on the memory. Even if my planned usage doesn't call for all the memory, I usually end up re-purposing the machine down the road and more often than not, have found the "extra" ram to be of value. I consider a two year old machine "brand new" I often deal with machines up to ten years old. OTOH: It's often wise to get new equipment. A friend of mine wanted me to max-out the RAM on his machine that took DDR-2 It was cheaper to just get a DDR-3 capable mobo and RAM (I used an inexpensive all-in-one mobo with the non-replaceable CPU) |

If your machine is using Virtual Memory a lot on regular basis with only one or two apps running, you need more RAM. It's as simple as that. You should almost never use VM. Its use should be the exception, not the norm. Stef |

Thanks for the correction. I never was very good as spelling those long, complex words. My wife just told me that I should have written U-turn, not EWE turn. Oh, well. I'll try to avoid this kind of errors in the future. |

It depends on which programs you are currently using and whether they are 32 bit versions or 64 bit versions. If they are still 32 bit versions then no additional amount of ram will help because the programs won't be able to access any more ram than 3GB. This is the case even if you are on a 64 bit machine because programs are also required to be 64 bit versions. If you are using 64 bit applications then clearly some programs would benefit. Adobe programs (CC, Photoshop, PSE 13 etc) would benefit from 8 GB ram because they are 64 bit versions and they are programmed to use additional ram. If you are still using the old versions of Microsoft Applications then clearly additional ram won't be useful here. Hope this helps. |

Actually, Gordon's part of the discussion is off-topic here. It should be in one of the alt.satellite.gps* newsgroups, where bad navigation is on topic. I think I might have missed the pun if he had said U-turn (said he, sheepishly). Sometimes my brain makes its own kind of U-turn... -- Gene E. Bloch (Stumbling Bloch) |
