monson Posted October 12, 2006 Share Posted October 12, 2006 Ever since I built my rig, I've been having issues with the same stutter/lag that others have been discussing on this board. I was wondering if there is any other solution to this problem with the Pentium D 930 other than just disabling one of the cores? It'd been nice to have both cores active and be able to reap the benefits. My setup is below: OS: 10.4.7 JaS with SSE3/GMA900 patches upgraded to 10.4.8 with Jas Update CPU: Pentium D 930 (3.0GHz running overclocked to 3.4GHz) Motherboard: ASRock 775i945GZ (onboard GMA950 video, Onboard Realtek ALC888 audio, Onboard Realtek 8101L LAN, all working perfectly with the typical mods) Memory: 512MB DDR2 PC4200 Kingston Value Hard Drive: 80GB 7200 Western Digital Wireless Card: PCI Netgear WG311T Thanks, Dirk For those wondering, the platform=ACPI idlehalt=0 trick doesn't appear to do anything for my computer. In fact, according to Xbench, my score is lower when I don't have one of the cores disabled (only 60.25) as opposed to when I do have a core disabled (99.73). That doesn't seem to make a lot of sense to me. Ideas anyone?

St0nehead Posted October 25, 2006 Share Posted October 25, 2006 Disable HyperThreading in BIOS... Link to comment https://www.insanelymac.com/forum/topic/30056-processor-stutterlag-with-d-930/#findComment-216654 Share on other sites More sharing options...
really_guest Posted October 26, 2006 Share Posted October 26, 2006 I've the same Mother Board...and the same stutter problem. I've disabled 1 core (cpus=1 in the Boot.Apple file) and now all works great (but withou a core ) How do you have overclocked the cpu ? I can't see anything for do that in bios (I've D 805 Intel CPU). Can you help me to increase my 2.6ghz (and the 2th core too ) ? Thank You Very Much Link to comment https://www.insanelymac.com/forum/topic/30056-processor-stutterlag-with-d-930/#findComment-217350 Share on other sites More sharing options...
zam Posted October 26, 2006 Share Posted October 26, 2006 Try to upgrade your BIOS. I had this problem with Asrock Conroe945G-DVI and a new BIOS version took care of it altogether.

Dean Gunraj Posted October 29, 2006 Share Posted October 29, 2006 actually, you have to realize one thing, the pentium D's pump out massive heat. Stutters usually occurin in Systems for 2 reasons, 1: inifinte loop (common, but not that common; replacing video card works) or 2: (thermal based throttling -- popular feature in intel CPUs)... can you run a temp monitor program while in OSX or some hardware temp sensor, and tell me what you heat output looks like when u experience a stutter?

really_guest Posted October 30, 2006 Share Posted October 30, 2006 unfortunally no I can see only Hard Disk temp..I've tested many software-temp without success. I can spend some money for a new cooler, but I've touched it in "running" mode and it is so cool. When I start my PC the stutter appear immediately. This motherboard work very well (100% hardware compatibility)...help me to bring up the 2th core! Many thanks!

boo50 Posted October 31, 2006 Share Posted October 31, 2006 also have heat problem on my D805 after changing stock cooler to TT Big Typhoon all problems gone. i think it's a heat problem... Pentium D serises is really HOT processors.. and stock cooler is really SUCK.

consolation Posted October 31, 2006 Share Posted October 31, 2006 I have an ASUS mobo, under CPU settings there's an "CPU internal thermal control" setting. If I change it from [Auto] I get a very sluggish system, auto works fine.
