kurt Posted April 24, 2006 Share Posted April 24, 2006 Does OSX recognise and use both processors on Pentium D chips, i know there are problems with this on laptops using the COre Duo.

Proteo Posted April 24, 2006 Share Posted April 24, 2006 Brand new Pentium D 830 over here. Both cores were recognized and used, and everything is running like a dream. I think I'm going to sell my AMD box in the next days Edit: If you can get an Intel D945GNTL or D945GNTLR mobo and a copy of Jas 10.4.6 DVD installer, everything, I mean everything, will be automagically recognized and set up, so you won't have to mess with patches and such.

kurt Posted April 24, 2006 Author Share Posted April 24, 2006 OK, thanks alot. Not sure which D series I will go with, but it's nice to hear it works. BTW, Is your audio working?

Proteo Posted April 24, 2006 Share Posted April 24, 2006 Yes. Stereo output, mic input and line input work ok. I tried first with Myzar disc, and sound/network were not recognized, so I had to use the sigmatel and IONetworking patches. After Jas DVD download finished, I installed again and everything worked out of the box. I even got a noticeable speed boost in rosseta apps, and 5 or 6 extra points in Xbench (if that means something).

AldousHxlE Posted April 25, 2006 Share Posted April 25, 2006 I can also vouch for the Pentium D. Both cores are seen by the system. Hey Proteo, do you notice anything strange concerning how OSx86 measures the speed of you D830? It sees my D820 2.8GHz as a 4GHz processor.

Proteo Posted April 25, 2006 Share Posted April 25, 2006 Yes AldousHxlE, it says 4.0 GHZ in the "About this mac" screen too. BTW, what's your score in Xbench?

kernalzero Posted April 25, 2006 Share Posted April 25, 2006 AldousHxIE - I've got a single core Pentium 4 630HT that is set at 3.0 Ghz in my bios but registers in profiler as a 3.8Ghz 2CPU processor (xbench below). TopazBar lists a possible fix here for this but I haven't tried it so I can't confirm it's effectiveness Link to comment https://www.insanelymac.com/forum/topic/15923-pentium-d-question/#findComment-102448 Share on other sites More sharing options...
AldousHxlE Posted April 25, 2006 Share Posted April 25, 2006 Proteo - Surprisingly, I thought my XBench scores were rather low considering the hardware I got running OSx86. On average, I score between a 78 and 79. What are you getting, just out of curiousity? kernalzero - Truth is, Im not too concerned with fixing the speed reading. As long as my system works the way it should, it could tell me Im running a damn Pentium Pro processor for all I care. lol I still remember almost having a heartattack when I first opened About This Mac after upgrading OSx86 to 10.4.4 lol Edit: BTW, I think its seeing your single core Pentium 4 processor as 2 CPUs because OSx86 mistakes HyperThreading as two distinctly separate cores. Can anyone verify that? Link to comment https://www.insanelymac.com/forum/topic/15923-pentium-d-question/#findComment-102470 Share on other sites More sharing options...
kernalzero Posted April 25, 2006 Share Posted April 25, 2006 AldousHxlE - I'll agree your xBench scores do seem alittle low. If you have an LCD you could turn off beam sync, if you have a CRT it's not worth it, too many bugs produced. look for a program called quartzsimple (or pm me). I would use this software to test it out because you have to repeat it after a reboot (so it's not permenant). There is a permenant method to disable it though. See if that boosts your xbench. thanks for the explanation of why it sees 2 cpus, i've been curious about that like you've been wondering about why your cpu isn't being picked up right Link to comment https://www.insanelymac.com/forum/topic/15923-pentium-d-question/#findComment-102603 Share on other sites More sharing options...
Proteo Posted April 25, 2006 Share Posted April 25, 2006 My Xbench score (with BeamSync enabled) is even lower, in the range of the 69-72 points. Once I disabled BeamSync, it raised to 109. I have 2 GB of RAM, so I was expecting to reach the 80-90's without disabling BeamSync.

kernalzero Posted April 25, 2006 Share Posted April 25, 2006 i'm hoping to buy another gig of DDR2 here soon and break into the 90s - 100's but we'll see, not sure it will boost me that much. I'd disable beam sync but i'm still running a CRT Link to comment https://www.insanelymac.com/forum/topic/15923-pentium-d-question/#findComment-102822 Share on other sites More sharing options...
AldousHxlE Posted April 25, 2006 Share Posted April 25, 2006 Wow, what a difference! Disabling BeamSync raised my XBench score to 102.09! Pretty sweet. I too am using a CRT monitor, and I couldn't see any major graphical glitches like everyone else claims (Only noticed it when moving Finder windows around.) On the other hand, I noticed it kept some apps from loading, one being the SNES9x emulator. I just bounced infinitely on my dock until I killed it. I didnt really see any major performance improvements besides my XBench scores, so for now I'll keep things as is. But thanks for the cool tip.

Can anyone verify that? Ya - On my box it see's two cores even though I have one. I do have hyperthreading. Turn off "beam sync" and your xbench scores will improve a lot.

kernalzero Posted April 26, 2006 Share Posted April 26, 2006 Yeah I'm unsure of the ACTUAL gains from disabling beam sync. It does increase the xBench scores but if it does nothing else is it worth it and how valid are the xbench scores if it does nothing for you? Does anyone know how much of a performance increase you get from doubling your DDR2? I'm thinking of moving from 1GB -> 2GB but wonder if it's worth the ~$90. Anyone have xbench scores to compare their systems with 1gb vs 2gb? i'd be interested to see that Link to comment https://www.insanelymac.com/forum/topic/15923-pentium-d-question/#findComment-103326 Share on other sites More sharing options...
marliwahoo Posted April 27, 2006 Share Posted April 27, 2006 Graphics improvment is reall with beam sync disabled. Nothing else really changes. Probably only works with flat panel displays.

iMacME Posted April 27, 2006 Share Posted April 27, 2006 just built my macintel with a Pentium D 805 2.66ghz last night, and i'm surfing the forums with it as we speak. it shows as a 3.8ghz. only thing i have to fix right now is sound. everything else seems to be working with the P5LD2-VM mobo! i'll be installing windows 2k3 r2 or xp x64 next.

kernalzero Posted April 28, 2006 Share Posted April 28, 2006 I dont' know the answer to this question so correct me if i'm wrong, but don't you have to install windows before any other os? I know when installing different versions of windows you have to install older versions before newer (98se then 2000 then XP) and then install linux if you want linux to 'dual' boot after windows is installed. I only assumed installing OSx86 would follow that pattern. I'm not dual booting any of my osx86 computers though so I could be wrong Link to comment https://www.insanelymac.com/forum/topic/15923-pentium-d-question/#findComment-104214 Share on other sites More sharing options...
AldousHxlE Posted April 28, 2006 Share Posted April 28, 2006 kernalzero: That really depends on your hardware setup. In my case, I have my Windows OSs on one hard drive, and OSx86 on another, so it didn't really matter in which order they were installed. As far as separate partitions within a single HDD, I think it does matter which order they are installed, but I'm honestly not sure what the order would be. BTW, I've been meaning to test out OSx86 XBench scores using only 1GB of RAM to see if upgrading to 2GB is really worth the cost, but school has kept me very busy. If I can get it done this weekend, I'll post the results here.

I'm not dual booting any of my osx86 computers though so I could be wrong i installed win2k3 after installing osx86 so no, order doesn't matter. as long as you have your partitions set up correctly, you should be good, as well as a boot manager that recognizes all your partitions you want to boot from. i did however have to set the osx86 partition back to "active" since windows insists on setting it's partition as active to boot and continue install. long time ago, and i'm talking several years back ... i had 4 separate OS on one machine, dos/win95, winNT, os/2 and linux.

kernalzero Posted April 29, 2006 Share Posted April 29, 2006 AldousHxlE - I appreciate and look forward to your benchmarking isse03 - thanks for clearing that up. I wasn't sure and didn't want to see anyone lose an install simply because their order was wrong. I've had several OSes running on a single box before too without issues as long as you have a decent boot loader.
