Hello Ladies & Gentlemen, Firstly, may I take this opportunity to say what a great site this is and evidently a wealth of knowledge, however I’m sure you are already aware of that!! My name is Richard and I reside in England (UK). We have owned our family PC for 4 years and we now think its time to upgrade a few of its components. Recently we acquired another PC (as part of a package from our ISP) which has similar specification to our first PC. The upgrades I have in mind are for each PC: Hard Drive, Ram and Graphics Card. Listed below are both PC’s and their intended upgrades. I would appreciate any constructive ideas, experiences and recommendations. Please also bear in mind that although I’ve been using a PC for 4 years, I have never attempted any ‘open heart surgery’ on a PC before, however I have received information and instruction (PC World) on how to do it!! Whether the info is correct and reliable is another story. Lastly, please also consider that I intend to upgrade both PC’s so my budget is limited as it is divided between both PC’s. Unfortunately ‘top shelf’ components are out of my reach, but good quality and value for money are sought. Would the following upgrades work and are there any other alternatives that you could recommend, make / brand and model etc? Make: Advent Model: 3512 SPECIFICATION Intel Pentium 4. 3.06Ghz. HDD 120GB (Samsung SV1204H). DDR - 512MB (PC2-2100) crucial.com incorrectly state (PC2-2700). GF4 MX440 128MB. 48 x CD-RW. 16 x DVD. Fax / Modem. Windows XP Home Edition. Possibly Windows Vista in the future. UPGRADES Gigabyte GeForce 7600GS 256MB DDR2 AGP8x (Model: N76G256D-RH). HDD 300 / 320GB IDE/PATA - I’m undecided here. I don’t want a ‘Raid’ array, but its either Western Digital or Seagate. So far the WD is slightly favoured due to its better value, bigger size and good report by PC Pro. Western Digital WD3200JB Caviar SE 320GB 7200rpm ATA-100 8MB Cache. Seagate ST3300831A Barracuda 300GB 7200RPM ATA/100 8MB Cache - OEM DDR / Ram - Undecided here too. I’ve been advised by two guys from PC World, one suggests to add another 512MB RAM either PC2-2100 or PC2-2700, maybe Crucial, Corsair or Kingston and 512MB DDR2 to the other PC. The PC2-2700 will allegedly work at a slower rate, in line with the original above. He also advises NOT to increase the RAM due to the limitations of the Advent and its processor, suggesting it may crash if using 1GB together with the installed 512MB original. The other guy in PC World said adding 1GB Ram to the installed 512MB DDR / DDR2 in each PC would be ok. Interestingly, Crucial state the following for the above PC: 'Maximum Memory: 2048MB USB Support: 1.x Compliant Standard Memory: 512MB removable Slots: 2 (2 banks of 1) Graphics Support: AGP4x' PC World have looked inside my PC and said the PC accepts AGP8x. Are Crucial correct or incorrect as they are with the RAM? Is this compatible with AGP4x? What is the difference and can I use the 7600GS? Our other PC is only branded externally by our ISP. Inside it has the following: SPECIFICATION Intel Pentium 4. 3.06Ghz. Foxconn Motherboard - 945GZ7MC. HDD 160GB (Samsung SP1644N) 7200RPM /2M/PATA. The ribbon only has one PATA/IDE interface connector, which is attached to the above HDD, but the motherboard has the facility to four SATA2 type connectors. As a result I’m looking to add a SATA HDD. DDR2 - 512MB Dynet (DNHM5U512B6FE - A5 DDR2 533 (4) 512 MX8). I’m informed that the installed RAM is equivalent to 1GB due to the BUS speed? HEC - 300AR-PTE 300W Power Supply. DVD - Writer. MATX Case. Windows XP Media Centre Edition 2005. Hopefully Windows Vista Upgrade very soon. Edited to add: UPGRADES for the above PC: Graphics Card: Inno3D Nvidia GeForce 7600GT 256MB PCI Express x16. HDD: Western Digital WD3200KS 320GB SATA2 16MB Cache 7200RPM DDR2 RAM: Crucial 1GB 240-PIN DIMM Unbuffered DDR2 PC5300 (667MHz). Model: CT12864AA667. Your help and thought are greatly appreciated - Thanks. Kind regards, Richard. P.S. Sorry for my long post and if I’ve posted in the wrong section.
