Need speed in OS X - Radeon 7000? |

7500 with Sonnet G3/500 card and OS X successfully installed and running thanks to XPF. Now how best to get OS X moving a little faster? I still need to install L2CacheConfig 3.3. How much difference will this make? I'm at 256K DIMM's and plan to add another two 128K for total of 512K. How much difference will this make? Finally, I am considering buying and installing the Radeon 7000 graphics card. If I can get this done successfully, how much will this speed up OS X? And, how should I approach installing the Radeon 7000 so as to minimize any potential problems, as I've seen discussed on this forum? Thanks. |

These PC Radeon 7000 cards uses to be faster (and about half of the price) than the original Mac edition. I have a retail PC ATI Radeon 7000 64MB DDR PCI and it flashed OK, runs very fast both in OS 9 and OS X, with all 2D and 3D features enabled in both systems. There is a detailed thread about how to flash a Radeon 7000 buried in this forum, not much deep... |

your best bet is to buy a PC Radeon 7000 and flash it with a Mac ROM. I recently flashed a Powercolor Radeon 7000 with VGA, DVI, and TV-Out. I don't know if the TV-Out works yet but everything else does. |

You can get a rough of your drive speed in X from a utilitiy called XBench. It is on Versiontracker. Despite what the drive speed is, you are limited to the bandwidth of the scsi bus itself. Internal scsi on old world is 10 meg/sec or 5 meg/sec if you have the second internal bus connector. The drive could go faster, but it won't if it is on one of these connectors. I wont go into the difference between scsi, ultra, wide, etc, but you can read about it here....... http://www.a2zcables.com/a2zcables.filereader? 3da6cec308fdc3242719424d361d0696+EN/userpages/37 A pci scsi card with wide or ultra will get you faster drive speed from that drive. |

I am running Jag off my 18.3 Quantum Atlas internal SCSI drive, which purports to deliver 29 mb/sec. Last night I checked ASP and saw that L2 displayed 0K. I then went to Sonnet and downloaded Tune Up and after installing it ASP now shows L2 at 512K. So, success and maybe some improved performance. Additional OWC DIMMs are on order. Now I'm looking for a good deal on the Radeon 7000. Thanks. |

One thing I forgot to mention is the speed of your disk. If you are running jag on on the "stock" disk on the main bus, you will be lucky to get ~5-8 meg/sec transfer. My stock apple drive on my 9500 clocks in at a whopping 3 meg/sec. Because of that, I run jag off my 2940 scra, using the helper disk function. I am getting ~20 meg/sec now, still not lightning, BUT did make a difference. |

"I still need to install L2CacheConfig 3.3. How much difference will this make?" if you are running the sonnet software WITH the X tuneup from their site, nothing, that software just enables the L2/L3 cache. It should be running already, check your ASP to see for sure. "I'm at 256K DIMM's and plan to add another two 128K for total of 512K. How much difference will this make?" should help speed thisngs up, the more the better with jag "Finally, I am considering buying and installing the Radeon 7000 graphics card. If I can get this done successfully, how much will this speed up OS X? And, how should I approach installing the Radeon 7000 so as to minimize any potential problems, as I've seen discussed on this forum?" assuming you are onboard VRAM: 2 MB (4 MB via 2 DIMM sockets), you WILL see a difference with regard to screen refresh, effects, etc. I have had good luck with this card, so maybe I have been lucky on the five different machines I have put one in on..... Still want more speed???, get a g4 800 chip in that puppy. The g3 500, though a great chip will be sluggish in X. |
