manmal Posted October 21, 2007 Share Posted October 21, 2007 Hi, are Core Duo CPUs (not Core 2 Duo) on "old" laptops (not macbook) fully supported by latest 8.10.1 kernel ? Or do they have the same problems as before (ie. 1 core disabled to work safely) ? Thanks! Mal Link to comment Share on other sites More sharing options...
candykane Posted October 21, 2007 Share Posted October 21, 2007 they work i got a 805 2,66 @4 GHz it works great. 8.10.3 is out ) Link to comment Share on other sites More sharing options...
Synaesthesia Posted October 21, 2007 Share Posted October 21, 2007 Pentium D is not the same as core duo Link to comment Share on other sites More sharing options...
manmal Posted October 21, 2007 Author Share Posted October 21, 2007 exactly, i was specifically asking about core duo CPUs . Is there anyone who has it running osx86 with bore core enabled with one of the latest ver (10.4.9 or 10.4.10) ? Thanks! Mal Link to comment Share on other sites More sharing options...
candykane Posted October 21, 2007 Share Posted October 21, 2007 If you don't know what your talking about use Google before you ansor and just look like a @$$! you can do it just type 805D in the Google window intel Pentium 805 D = a dual core @ 2,66 Ghz! Losers So yes they do work! Also single core intel Pentium 4 with sse 3 and hpet (2004 models and the celeron D) all work with 10.4.10 8.10.3 for 10.4.9 any P4 with sse 2 will do just make sure you got a sse2 distro , and a kernel that supports sse2 Link to comment Share on other sites More sharing options...
Skitals Posted October 21, 2007 Share Posted October 21, 2007 There is no hope for candykane. Just ignore him. I don't know if it makes a difference between laptops and desktops, but my new machine has an e2140, based on core 2 duo architecture. Runs great, about this mac reports 2.8ghz core2duo (im overclocking). Link to comment Share on other sites More sharing options...
Synaesthesia Posted October 22, 2007 Share Posted October 22, 2007 OK GUYS. Some clarification. We all know Pentium D and all other DESKTOP Intel Dual core cpus work with both cores enabled. However, with the laptops, many Core 2 Duo & Core Duo cpus only work if cpus=1. (otherwise they stutter) Now as far as I know this is a problem, especially on dell laptops. Here is a thread discussing this Link to comment Share on other sites More sharing options...

macgirl Posted October 22, 2007 Share Posted October 22, 2007 Now as far as I know this is a problem, especially on dell laptops. I believe that the newest Dell Notebooks doesn't have this problem, at least my Dellintosh (XPS M1330) doesn't have stuttering with the both cores enabled, but this is with the 10.4.10, I observed stuttering with 10.4.8 when I installed.

Dainix Posted October 22, 2007 Share Posted October 22, 2007 My roommate has a Toshiba Core Duo, and has had no luck. Every now and then, both cores will startup normally, but to maintain full stability, one core has to be disabled. Link to comment Share on other sites More sharing options...
Azurael Posted October 22, 2007 Share Posted October 22, 2007 Both cores (with a T2300) work fine in my Twinhead H12Y, as do both cores of a T7200 in the same machine, with 8.9.1, 8.10.1 and 8.10.3 kernels. And for clarification for mister Core Duo = Any dual core CPU: Pentium D = Two nuclear reactors Netburst (Pentium 4) architecture chips glued together; badly. Core Duo = Modified Pentium-M microarch with shared L2 cache and two cores. Only available as a mobile CPU, uses the same socket/chipset/computers as the first generation of Core 2s (hence the interchangability) Core 2 Duo = Based on the new Intel Core microarch. Available as desktop and laptop CPUs. There should not be any difference in the operability of the Core Duo & Core 2 Duo under OS X in the same machine. From a software point of view, the only differences are SSSE3 and AMD64 support (although at a hardware level they're quite different!) The likelihood is a machine that won't work with a Core Duo still wouldn't support both cores if upgraded to a Core 2. Sounds like a BIOS bug if we're talking about i945 here (and I'm not aware of any Socket M laptops which don't use i945/940...) The best bet to get both cores working is to play around with different kernels; different versions and different patches. Link to comment Share on other sites More sharing options...
yaleyu Posted November 6, 2007 Share Posted November 6, 2007 I believe that the newest Dell Notebooks doesn't have this problem, at least my Dellintosh (XPS M1330) doesn't have stuttering with the both cores enabled, but this is with the 10.4.10, I observed stuttering with 10.4.8 when I installed. Maybe that's why my Dell 640m stuttering with dual core enabled. Even it's Leopard.
