Th3_uN1Qu3 Posted March 31, 2008 Posted March 31, 2008 Hi there!Is there any difference between 1x1GB and 2x512 mb RAM under Win98?Can I get any benefits of dual channel (2x512 mb), or shell I go for the cheaper solution - 1x1GB?Any difference in fixing the error with one or two sticks of RAM? 2x 512 in dual channel will give you better performance since it's a hardware thing, it doesn't depend on the OS at all. And if it's one or two sticks windoze will not care, therefore the workaround will still be needed.
tonich Posted April 1, 2008 Posted April 1, 2008 Thank you all for the replay!I consider building a new system, based on MSI K9MM-V motherboard. I will definitely let you know my particular solution, at a time.

rainyd Posted January 19, 2010 Posted January 19, 2010 (edited) What value guys, you recommend for 1 GB of RAM?I've set MinFileCache=64 MB, MaxFile Cache=256 MB and chunk size=1024 (what sort of benefit you can expect with higher value of it?).Btw, I'm interested what you think abou that article: http://www.thpc.info/ram/vcache.html Edited January 20, 2010 by rainyd
dencorso Posted January 19, 2010 Posted January 19, 2010 I use the following values: [vcache]MinFileCache=4096 MaxFileCache=393216ChunkSize=2048 NameCache=4096 DirectoryCache=96And I do use Xeno86's fixed vcache.vxd, which respects these settings, but will limit the cache to 384 MiB, and not 800 MiB as the original MS file does, when these settings are absent from the system.ini or, more important, on entry to "Safe Mode", when all of msdos.sys, autoexec.bat, config.sys, system.ini and win.ini are ignored.The web-site you pointed to is one of the sources for 384 MiB, and Gape's usage of it throughout most of the versions of his uSP (although I think now he's dropped it, but I don't know why) is also a good reference that it actually works well and reliably in the real world. I've discussed this point in the past, rather extensively, as have also others, notably soporific. If you delve head-first in my > 1 GiB list thread, linked below, to the right side of my signature, you'll find all that has been discussed about it. The present thread, BTW, is also linked from there, of course.
rainyd Posted January 19, 2010 Posted January 19, 2010 Dencorso, thank you for the reply - I'll check those settings. Btw, for tweaking them, I'm using old but fine freeware program called Cacheman (version 5.50).
loblo Posted January 20, 2010 Posted January 20, 2010 (what sort of benefit you can expect with higher value of it?).Well VCache is disk data cached in memory for reaccessing that data without needing to fetch it to disk again so the higher the max value the better IMO. The maximum size VCache can have is 800MB if I am not mistaken but out of memory issues with some applications are known to exist if it is set to above 512MB.
rainyd Posted January 20, 2010 Posted January 20, 2010 (edited) Loblo, my question was concerned specifically to the chunk not Vcache size. Still, I don't know what is advantage having 2048 bytes instead of 1024. Edited January 20, 2010 by rainyd
loblo Posted January 20, 2010 Posted January 20, 2010 Well I have been using chunk values of 16kb and 4096kb and I can't say I have seen much of a perceptible difference if any. Presumably chunk size is akin to cluster size in a filesystem and should have the same advantages/inconveniences as those, eg small size would mean less wasted space but more propensity to be fragmented perhaps.If someone knows better, let us know.
dencorso Posted January 20, 2010 Posted January 20, 2010 Since the memory is paged anyway and the memory page is 4 kiB, 4096 (= one page) is the maximum value that makes any sense, IMO. I use half that because I couldn't find a test condition capable of showing any difference between those two settings, and chose the lower arbitrarily. Notice that the ChunkSize is expressed in bytes, not kiB.The definitive reference about the ChunkSize is Adrian Rojack's Optimization Guide. All this have been said in the thread I pointed to, so I'll stop repeating them from this post on. C'mon: it's all pointed to in the > 1GiB thread...Start reading!
MDGx Posted January 22, 2010 Posted January 22, 2010 Important...DirectoryCache is an invalid value, does not exist:http://www.msfn.org/board/index.php?showto...80800&st=38HTH
Sound Lover Posted February 7, 2010 Posted February 7, 2010 (edited) RE: dencorco's POST # 72I linked to: Adrian Rojack's Optimization Guide and got a Virus pop-up."WARNING!Critical Security Warning! Your PC was infected with a self-infecting virus after Spyware attack. Windows Defender Scanner will perform a free scan of your PC to find all System Threats.<link removed>I didn't trust this pop-up but I had to shut down my browser (Firefox 2.0.0.20) with CTRL-ALT-DEL to exit this site.Ran SpyBot 1.6.2 and SuperAntiSpyware 4.24.0.1004 but found nothing.Should I dig deeper?jp Edited February 7, 2010 by dencorso Removed live link to the site offering malware.
dencorso Posted February 7, 2010 Posted February 7, 2010 Never post a live link to any site offering malicious content! Consider yourself warned!Never trust pop-ups of unknown origin, because they almost always are scams temselves! There's no virus at Rojack's page. I checked that myself right now. As for the specific pop-up you saw, it *is* a scam. You'd really be in trouble if you had downloaded and installed their "anti-virus", which is in fact a malware. Read more about it here (link). But since you didn't trust it and downloaded nothing from it, you're probably on the safe side. No need to dig any deeper, in what regards to that pop-up, unless it keeps on appearing on other unrelated sites (in which case you may have got a browser hijacker added to your browser).
