I have always found that win xp is much more usable with 2gb but maube for this situation 1gb will be plenty |

I have always found that win xp is much more usable with 2gb but maube for this situation 1gb will be plenty If using Photoshop, yes. For most other applications, more than 1GB just doesn't do much. With Win7/Vista the system is much more responsive, XP- no difference. Grant Darwin NT |

I have always found that win xp is much more usable with 2gb but maube for this situation 1gb will be plenty I have found that as well, but you don't plan on really using it do you? Also in some cases using 4 dimms instead of just 2 can slow down memory performance. SETI@home classic workunits: 93,865 CPU time: 863,447 hours |

Nope its just for seti! |

Nope its just for seti! S@H Enhanced uses about 32 MiB per instance, Astropulse about twice that. 2 sticks of 512 MB low latency PC3200 would be better than 2 ordinary 1 GB sticks. Another thing you might consider is trying to find a cheap used AGP (or even PCI) graphics card rather than having the on-board graphics contending for memory. Or just avoid using graphics... Joe |

WeLl its built need a low profile low noise fan and I am sorted I have a 12cm ultra quiet fan I might hack a hole in the case and put it in over the heat sink to replace the current cooler but is it worth the risk?. |

Sometimes. If it ain't broke don't fix it applies, bt sometimes it's fun to do so anyway :D SETI@home classic workunits: 93,865 CPU time: 863,447 hours |

well the cpu fans a tad noisey so i think from my 11years experience of computers its on its way out. I was only thinking of using the 12cm fan because its the sharkoon golf ball fan http://www.scan.co.uk/Products/120mm-Sharkoon-1000-Golf-Ball-Quiet-19-dB(A)-Case-Fan-367-CFM and very quiet! |

well the cpu fans a tad noisey so i think from my 11years experience of computers its on its way out. You may like to consider the Nexus 12 cm case fans....they're really quiet. I got mine from Aria . They have the 4 pin connector for the later motherboards, but I use two on the 3 pin connections for the case (they can be used as normal on 3 pins), whilst the 3rd is attached to a Scythe Ninja 2. As to memory, I'd still go with 2 GB of good quality PC3200 - my old P4s noticed the difference and all HT units.... 2.4GHz, 2.6GHz, 2.8GHz and 3.2GHz. Win XP has to be the OS of choice...you might be able to get a cheap copy of XP Pro or XP 64 and you'll be wanting an Optimised Application for crunching out the numbers. That does tend to make the P4 run a bit warmer, but you probably won't see the horrendous levels that I did with my 3.2Ghz CPU, resulting in a Scythe cooler! Have fun. Don't take life too seriously, as you'll never come out of it alive! |

im still looking for a low profile quiet cooler, i get paid on the 20th so might purchase one then |

Because so many people complained about Vista being a memory "hog" (which frankly wasn't even close to truth), Sorry for jumping in this thread late... From my experience working in my IT dept, a fresh image of WinXP Pro(32) uses in the 400-500MB ram range, while a fresh image of Vista Business 32 (with the same programs) uses in the 800-900MB range. Just going on my real-world experience. "Life is a tragedy for those who feel, and a comedy for those who think." "I never get into an argument that I cannot win." ![]() |

Because so many people complained about Vista being a memory "hog" (which frankly wasn't even close to truth), From my experience working in my IT Department, a fresh image of WinXP Pro 32bit the kernel uses approximately 40MB of RAM with the average RAM usage hovering around 400MB fully loaded. Comparatively a fresh image of Vista Business 32bit the kernel uses about 85MB of RAM with the average RAM usage hovering around 450MB, based upon my real-world experience. |

Dave: I don't know how much an Atom 330 with an ION GPU cost over there, but Sten-Arne's seems to be cranking along at a decent pace. I have one rocking in my car... really surprising for 1.6ghz /core Total cost was $350 US (case ,motherboard, 1tb hd and 4gb ) |

Because so many people complained about Vista being a memory "hog" (which frankly wasn't even close to truth), Interesting. Obviously something is different. Is that with certain features (like Aero) disabled? Perhaps our techs haven't been as adept in removing unnecessary features. "Life is a tragedy for those who feel, and a comedy for those who think."

Because so many people complained about Vista being a memory "hog" (which frankly wasn't even close to truth), No, Aero is fully enabled, and using the default install options (no slipstreaming). Are you guys counting RAM that is allocated to SuperFetch, which should not be counted as "in use" by the OS? |

S@H Enhanced uses about 32 MiB per instance, Astropulse about twice that. 2 sticks of 512 MB low latency PC3200 would be better than 2 ordinary 1 GB sticks. That is undoubtly true, on my (3) QUAD's, all memory has been changed and halved One (64BIT XP) has DDR2 OCZ 400MHz @1,8V 5.5.5.13; or 533MHz @2,1V 5.5.5.13; 2T. Btw, the QX9650 is undervolted, well it runs at 1.16V 3333MHz.(A slow-Down, for now) Memory latency is quite important as the RAM already is the 'bottleneck', thats why Quick-Path Interface, is implanted. For one reason. Or something VISTA Home Premium 32BIT, calls ReadyBoost.sfCache and uses a fast USB-Device like CF III cards, atleast full USB2.0 speed (400MBIT/s)(or 480?). Sorry for this distraction, building a new PC, sure nice to dream about, though nicer to actually build one, I'm sure, atleast, I am :) There almost too many nice and good MoBo's, graphic card's and CPU's! Not to forget casing, PSU, fan's, CPU-Coolers (nitrogen/aqua/air) Harddisk's or better/faster Solid State Disk's (SSD's). Although ever tried running Windows, whithout a Paging File? Ofcoarse it's possible and works fast, if enough RAM is present, only a BSOD. . . ., well you can guess :\ ![]() |
