    I believe Mega is correct. I'm testing the T-bird system against an identically clocked and similarly configured PIII/P3V4X system, and the T-bird system is faster at everything I've thrown at it so far, except SETI: Quake3, Content Creation and Business Winstone 99, SiSoft Sandra's synthetic CPU and Memory Benchmarks.

      The good thing about 3D 2000 & Unreal is that it stresses your graphics card too ,which Prime 95 (I believe) & SETI don't.
      The extra heat output & the use of the 3D side of the graphics card can make a big difference

        The Tbird is getting killed because the RAM is operating at 100MHz. Wait until DDR (200 and 266) come out. The Thunderbird should kill a PIII using a FSB of 133MHz at that time.

          Unless you're plugging a T bird into an old AMD chipset board it will be using a memory bus of 133MHz & not 100 MHz(unless it has been set to 100MHz for PC100 RAM).
          But yes the DDR boards should be awesome ,can you imagine the SETI WU times?? :Q

            Assimilator1 is correct.
            UT is my stability test of choice.
            My rig will run @ an 8mz higher fsb on almost anything but UT.
            UT errors on start up.
            It's typical of game programmers to stress the system more than regular app programmers.

              As long as we're comparing seti times on Ahtlons (or at least we were), mind if I mention something? If you guys are all running seti and getting wu times of @ 6 hours, why is my athlon 700 @880 (2/5 cache) doing 9+ hours?

              It's really irritating. I installed Seti originally on my old system but when I built this one, I didn't bother to reinstall it. I just moved it to the hd I'm using as a slave now. Do you think that is the problem? I am using the Home Client v.2.00.

              sys specs so you can make fun of me:
              Athlon 700 @ 880 (8.5x103) at 1.7 vccore
              MSI K7 PRO
              128 megs crap ram
              I don't think you need to know more, do you?

                Muad'Dib,

                Have you tried version 2.40?

                Your problem may be your "128 megs crap ram". But 6 hours is good for slow RAM, if slow is what you mean by crap RAM.

                  What I meant by "crap ram" is generic pc100 which will run at least 110 fsb at cas2.

                  Oh, and as I said, I'm running WU's at 9+ hours....

                    Muad'Dib,

                    Thanks for pointing out my error, it takes you 9+ hours to run a WU.

                    RAM speed is very important. I mentioned in one of my earlier topics that I am using a PIII at 800MHz (FSB is 133MHz). I dropped the CPU speed back to 690MHz and increased the rest of the FSB to 153MHz. Time to crunch WUs was about the same, so RAM speed is vital.

                    When DDR and motherboards that support it come out, Athlons should do much better. On average, it now takes me less than 5 1/2 hours to complete a WU.

                    Fast subsystems are very important, more is needed than a fast CPU to get good WU times, unfortunately.

                      DOH! Ok, I decided maybe it would be a good idea if I upgraded to 2.04. NOPE! Now it's taken 1 1/2 hours to do 11%! This is worse than before! Grrrrrrr

                        Muadib,

                        I hope you're using the CLI Version,do you? Are you running any other software or screensavers?

                        With nearly the same setup as you(650@840 using 7,5x112) i get exact 6 hours.

                          Muad'Dib,

                          MegaManX4 has a good point. When I asked if you were using version 2.40, that is the client version. With it you cannot keep track of what percentage is finished, but I have found it much faster than the screen saver version.

                          And, to gain more speed, turn off everything running in the back ground that you do not need (by using the Control, Alt, Del keys).

                            If you add the -verbose to the command line ,v2.4 WILL show you the %

                            Muad'Dib

                            My fathers Athlon 700 PC I just built does a WU in about 6.5hrs (v2.4 CLi).

                            Here's the specs
                            Athlon 700 (1/2 speed 512K cache)
                            Abit KA7 KX133 board
                            Cheapo PC133 RAM which will run at CAS2 ,fast timings in bios ,133MHz

                            It looks like your problems could be ,the 2/5 cache divider (cache speed holding back the cpu).Your RAM is only at 103 MHz.
                            What chipset is your m/brd? Can it set the memory bus seperatley? Will your RAM run at 133MHz?

                            BTW v2.04 a GUI version needs the 'blank screen' to be set to less than 5mins for it to produce good WU times.Then it is only SLIGHTLY slower than the CLi v2.4

                              I tested one WU with different FSB settings and come to the conclusion that every Mhz on the FSB lowers my SETI time about 4 minutes. This is on an Irongate chipset so results may differ if using PIII chipsets.

                                Where/how do I get the CLI version?

                                I too thought it might be the cache, but then I thought that maybe there was enough speed difference to make up for it? I was getting similar results when I was running at 1/2 cache speed at 700.

                                Oh well, I suppose it's not that important anyway....
