| 271660 | 2004-09-13 00:09:00 | You also need to take into accout what OS will be used and what programs will be run. Linux ultilizez system resources far more effeciently than windows does. Also if your only running a CMD prompt then the extra RAM wont make a difference. If the systems were different you'd also need to take into account chipset and motherboard brand. These will only make a small difference but still need to be taken into account. If the CPU's have an FSB of 100MHz then id expect the system with more ram to offer better preformance. It wouldnt be all that noticable. |

It > wouldnt be all that noticable . Peter, This Thread has been most usefull I didn't have good comprehension of this at the beginning of this thread . Electronics and Hydraulics are closley related, you have: amps, watts volts . We have: flow, pressure, back pressure . Both mediums are inherrently lazy . The 100 Fsb on the CPU works as a relief valve . The extra 33mhz "pressure" in the 133 stick is dumped . as I was trying to obtain a balance of performance the extra 32 meg stick in the Pc 100 machine may be removed . This will be close enough . With an FSB above 100, the scenario would change, and become more complex, I now see . Thank you . |

| 271662 | 2004-09-13 00:59:00 | The thing with FSB is that you need to match the FSB of the CPU to the FSB of the RAM. If RAM is faster than the CPU it will just be clocked back to match the CPU (it is possiable to force the RAM to run at its native speed but this offers no preformance gain). If the CPU FSB is faster than the RAM then you create a bottleneck and are limiting your preformance. Since your using SD-RAM its safe to assume your using an older system such as P3. With the new CPU's such as the new Athlons and P4's it get slightly more tricky as you have to deal with the system bus and the front side bus(FSB). For example Intel quad pumps the FSB on the P4 making the system bus effectively 4x the FSB. |

| 271663 | 2004-09-13 01:47:00 | your combo of Electronics and Hydraulics makes it confuseing as hell :( just to make it a little more complex not all mobo's have the ram the same speed as the fsb. there are a few that will run a 100mhz fsb but a 133mhz ram speed. it helps when you mention the exact hardware being used :) |

The Fifth unit in each has 2 network cards, and connects to a master = 21 comps . connected to a win lan with a dhcp net gate = 25 comps . Each group (Except the win group) . is a group of clones just to make it a little more complex not all mobo's > have the ram the same speed as the fsb . Another good tipbit . as was the different dynamic loading one . |
