rage2122 Posted November 5, 2006 Share Posted November 5, 2006 I just installed the new 10.4.8 DVD and tried both kernels and still have stuttering when I have both cores enabled. Anyone else with a Core Duo or Core2 getting past the stutter with the new kernels? thanks for any info Rage Link to comment Share on other sites More sharing options...
semthex Posted November 5, 2006 Share Posted November 5, 2006 Semthex, all, do you know if anyone is working on SSE2?Is there any timeframe for that to happen? Join #kernel on IRC we might have asolution for you Link to comment Share on other sites More sharing options...
really_guest Posted November 5, 2006 Share Posted November 5, 2006 please, no time for irc can you explain here how can we enable the 2 core ? I've Intel Pentium D 805 MANY Thanks!! Link to comment Share on other sites More sharing options...
Chrysaor Posted November 5, 2006 Share Posted November 5, 2006 I am very interested for a solution to Core Duo's dual core issue as well. Unfortunately, I can't log in to IRC. Link to comment Share on other sites More sharing options...
bruin4life Posted November 6, 2006 Share Posted November 6, 2006 me neither, i can't join irc. Semthex i am running your kernel. Can you please bless us with a fix? It's killing me to have a Core 2 Duo system and not be able to run both cores simultaneously without the system stuttering or stalling for like 15 seconds. Thanks in advance Link to comment Share on other sites More sharing options...
mifki Posted November 6, 2006 Share Posted November 6, 2006 meh, all my core 2's work fine Link to comment Share on other sites More sharing options...
bruin4life Posted November 6, 2006 Share Posted November 6, 2006 what do you mean they all work fine? do you have any special "kernel flags" like "idlehalt=0" etc.?? i have an e6300 core 2 duo, and it stalls every so often just like the amd guys. i will not run with one core!! we need a fix for this.

rognvaldr Posted November 6, 2006 Share Posted November 6, 2006 I have an e6300, my solution was to use fsb=266 at startup. Worked like a charm for me. Rogn Link to comment Share on other sites More sharing options...
hiroo Posted November 6, 2006 Share Posted November 6, 2006 i have a E6600 and haven't experienced any stuttering at all, even before I set fsb=292 to match my hardware. 10.4.8 semthex (from jas's first dvd). Link to comment Share on other sites More sharing options...
bruin4life Posted November 6, 2006 Share Posted November 6, 2006 thats what i did too. i set fsb=266. i still get some stuttering. I have: ASUS P5B Deluxe e6300 Core 2 Duo 1.86ghz Fsb = 266 mhz 1 gig dual channel ram (2x512mb) Sata WD Raptor 150 gb running in AHCI mode Please, I really just wanna run with 2 cores and have no more stuttering. its driving me crazy. thanks in advance.

flaker Posted November 6, 2006 Share Posted November 6, 2006 same problem for me... Mine is a Dell XPS M1210 laptop (Core2DUo T5600).. It doesn't work with 2core, and I tried fsb=166 but no success.. Now, OSX shows me that my cpu is Core2Solo... Link to comment Share on other sites More sharing options...
Chrysaor Posted November 6, 2006 Share Posted November 6, 2006 Interesting. Mine says 2.13ghz (its 1.73 really) Core Duo in About this Mac. In System profiler it says "Number of CPUs" = 1 with cpus=1 and fsb=133, in a newer version SPPlatform.spreporter its changed with "Number of cores", so its still 1.

joe75 Posted November 6, 2006 Share Posted November 6, 2006 I have tried with all the kernels I can get my hands on, and can not have both cpus enabled A couple will let me run longer but still end in freezing, the first semthex or mifki causes reboots. All, except the newest semthex disable internet when both cpus are enabled The best for me so far is "DaemonES", it seems to keep my clock running a little better, but still cpus=1 @Chrysaor, with "DaemonES" kernel, if I set fsb=266, my ATM says 2.93 and my clock will slow, if I do 166, it will set at 1.83 and my clock is right Link to comment Share on other sites More sharing options...

Sabr Posted November 6, 2006 Share Posted November 6, 2006 My Core 2 Duo E6300 works absolutely fine. No problems whatsoever. Using 10.4.8 on Mifki's kernel. My kernel flags: -v fsb=400 You could try platform=X86PC as a kernel flag too - that may fix it Link to comment Share on other sites More sharing options...

leodm Posted November 7, 2006 Share Posted November 7, 2006 DaemonES kernel rocks I specify fsb=460(e6300@460x7 on a p5b deluxe), and the clock is correct. dual core works just fine. Link to comment Share on other sites More sharing options...
Sabr Posted November 7, 2006 Share Posted November 7, 2006 SABR & AndyMS, do either of you think my problem could be, mine is 667MHz , because I see allot of core2s with no problems What do you mean yours is 667Mhz? You mean your RAM speed? so you're saying i should run mifki's kernel? and btw, my fsb=266, but what was the '-v' flag for again? thanks guys. You could give it a shot. I haven't tested Semthex's kernel, so I can't say that Mifki is the only one that works for Core 2 CPU's, but it's worth giving Mifki's a shot. And the -v flag is so you can see what goes on "behind" the grey Apple loading screen. It is technically called Verbose mode, and it allows you to see any errors that may be produced, which you would not normally see without the flag. It causes a load of text to be splurged out onto the screen as the OS loads. Link to comment Share on other sites More sharing options...
johnny1051 Posted November 7, 2006 Share Posted November 7, 2006 Fellow Disgrunted Dual-Core Users, Same problem here, my setup is unusable with out cpus=1, have tried various fsb switches, idlehalt=0, fn=3, have disabled / enabled speedstep in bios, have changed my proc and memory speed to match, and have banged my head against the wall for hours (owie). I've settled for overclocking my proc to 3.02 to compensate for being down a core. I thought only the AMD guys had this issue?? Well, it will be sweet when I figure this out..... After all, who would have thought we'd have QE/CI on Nvidia cards?? we've got alot of brainpower here, just a matter of time. Link to comment Share on other sites More sharing options...

johnny1051 Posted November 7, 2006 Share Posted November 7, 2006 By itself, or in a big kernal switch cocktail? I tried that last release, 10.4.7 but, I think alone....I remember trying the platform=ACPI switch as well at one point or another.I'll give it another shot. THX P.S. Has anyone assembled a list of desirable BIOS settings? Link to comment Share on other sites More sharing options...
joe75 Posted November 7, 2006 Share Posted November 7, 2006 What do you mean yours is 667Mhz? The processor speed Intel Core 2 Duo Processor T5600 (2MB/1.83GHz/667Mhz) Link to comment Share on other sites More sharing options...
Sabr Posted November 7, 2006 Share Posted November 7, 2006 The processor speed Intel Core 2 Duo Processor T5600 (2MB/1.83GHz/667Mhz) Oh, ok... Errm, I don't think that would have anything to do with it, but I'm not 100% sure. The problem with OSx86, is hardware. Everyone's is different, and that's why everyone has different problems...
