Hi Gang,I am in a position where I can pick up some more RAM at a really good price, but I didn't want to waste the money if it wont do anything, so I thought I'd ask here and see what some of you thought.I will post my specs below this, so you can see what I have got. but, before I do that, let me tell you about why I'm thinking of this first.I plan on staying with FS9.1 for a good while yet, just personal choice, and I plan on keeping this PC as is for a while too.It's a good machine that has served me very well, and has never given me any real problems, so I'm keeping this too until all the paraphernalia has been sorted out with Vista, and all the hardware stuff, then I will make the leap.So, I have two sticks of Corsair DDR XMS3200 TwinX CAS2, and I am thinking of adding another two sticks.Do you think that I will see any real differences, not just in FS9, but Joint Ops, and Ghost Recon III, and the general day to day running of the PC etc.Many Thanks for any feedback you might have, My specs are below.ABIT IC7 MAX3 800MB FSBIntel Pentium 4 Northwood 3.40Ghz 800Mhz Seagate Barracuda 160 GiG Serial ATA HDD.1024MB Corsair DDR XMS3200 TwinX CAS2 Low Latency RAM.Vantec Stealth 520W PSU.ATI XT800 Platinum Edition 512MB.Hercules Digifire 7.1 Sound Card.The CPU and GPU are both Water Cooled

Hi Steve, I'm not a RAM guru but nevertheless... :-) Your chipset should be able to handle 4 double-ranked modules. If you do it, I'ld memtest it for some 30-50 passes (at least). At 1h per pass... :-) If you want to know how much RAM your system is using, perhaps download MemStatus and check the figures? With FS9, the positive effects of 2GB seem to be relatively limited. FWIW, I hardly ever had good experiences with low latency RAM - many compatibility issues. Therefore, IMHO, if two 1GB sticks of normal PC3200 RAM are equally priced or even cheaper than 2pcs 512MB LL modules, I'ld definitely opt for 2x1GB. Hope this adds to thoughts, kind regards Jaap

Hi Jaap,thats useful to know, but what I really wanted to know was would I see any benefits from adding the extra RAM, not just in FS9, but other applications and the operating system itself,Thanks,

Steve,Yes you would any added ram for XP is a good thing (not overkill ofcourse with like 4 or 8 in xps case).. but yeah 2GB wouls help in opening programs faster and will in general speed things up in so that XP doesnt have to use the swapfile soo much...dont expect speedups as a cpu would, but it will def. help.ps. ditto on what Jaap said about memtest and 4 dimm support.one thing with 4 dimms though, if you are now running with 2 dimms at DDR400 (PC3200) speeds, adding 2 more dimms, will with most mobos result in running the dimms at DDR333 speeds.. wont be that much of an issue, but just an extra FWIW to you ;)

thanks guy's,it's appreciated.

Sorry for missing out on the apps, Steve. Hope you were able to draw some conclusions nevertheless. I'm on 2GB too long to make a reliable judgement anyway. :-) HST, I'm s l o o o w l y building my first 4GB FlyTendo... It memtested over a week... Why? When I saw 1.8GB on the FSX-counter, I went: "Eeeaaacckk!" I have this funny 'thing' doctors haven't found a name for yet. Symptoms: I get extremely nervous when a certain percentage of what's in the box is exceeded. It's terrible! My hand performs Dr Strangelove kind of moves to where a wallet would usually be... 1.8GB, eeeaaacckk! I've suggested 'Specicitis' but the decision is still pending... :-) Maybe the docs are looking for a more dramatic name like MultipleSpecicitis or something alike? :-) Have fun Jaap
