bofors Posted December 16, 2006 Share Posted December 16, 2006 In my lastest overclocking adventures I am noticing a couple things about OS X. First of all, Windows seems to be more stable than OS X (10.4.8 with DaemonES kernel). I am wondering if anyone else has observed this. The second thing is that OS X does seem very stable much above 3.6 GHz on Conroe either. While I am sure that this is in part due to the limits of my air cooling and quality of my CPUs, it does not explain the fact that I can boot OS X at 3.8 GHz. It is just not completelty stable unless it is slowed all the way down to 3.65 GHz, which I think is a little too much. Finally, I am wondering what others are using to test for stability. Just runing Xbench is not good enough for my needs, I need extended dual thread performance, so I have been running Power Fractal with the maximum count (it takes about half an hour): http://www.versiontracker.com/dyn/moreinfo/macosx/10540 Link to comment https://www.insanelymac.com/forum/topic/35984-os-x-stability-above-36-ghz-on-conroe/ Share on other sites More sharing options...
asap18 Posted December 16, 2006 Share Posted December 16, 2006 have you been limiting your tests to daemones's kernel or have you experienced the same with semthex, mifki's kernels?

bofors Posted December 16, 2006 Author Share Posted December 16, 2006 I have not worked with any of Semthex's kernels. I had thought that the DaemonES kernel that I am using was the latest from Mifki's source code: http://forum.insanelymac.com/index.php?showtopic=32381 Link to comment https://www.insanelymac.com/forum/topic/35984-os-x-stability-above-36-ghz-on-conroe/#findComment-256095 Share on other sites More sharing options...
TofuTodd Posted December 17, 2006 Share Posted December 17, 2006 I am on a conroe with air cooling too. I had to raise my core voltage to get apps like handbrake stable I am at 3520mhz with an e6600. I have also had a few KPs here and there, but nothing repeatable so I can only assume it has to do with excess heat. Temperature Monitor reports my die temp at 72 C, although I Have no idea is the app is accurate. Handbrake was the best test of stability for me, os x seemed fine. but handbrake would unexpectedly quit an hour into an encode... I am also using sem's beta 8 kernel, which I consider a must for overclockers due to auto bus speed timing.

asap18 Posted December 17, 2006 Share Posted December 17, 2006 Do you think in the 64 bit versions of osx in the future this problem will be eliminated?

bofors Posted December 18, 2006 Author Share Posted December 18, 2006 I am also using sem's beta 8 kernel, which I consider a must for overclockers due to auto bus speed timing. The DaemonES kernel also automatically detects FSB speed for correct timing.

bofors Posted December 18, 2006 Author Share Posted December 18, 2006 Do you think in the 64 bit versions of osx in the future this problem will be eliminated? First of all, I am not even sure if this is a bone fide "problem". That is why I started this thread, to see if others have noticed such a phenomena as OS X being less than 100% stable above 3.6 GHz. Whether OS X is 32-bit or 64-bit should have no direct effect on its stability. But in general, changes in the kernel certainly certainly should be pronounced.

bofors Posted December 20, 2006 Author Share Posted December 20, 2006 Apparenty there is a slightly newer version (for which I have sent Daemon a PM), but I have posted the one I am using here: http://forum.insanelymac.com/index.php?act...ost&id=5798 Note that the download includes a version of AppleSMBIOS.kext that the kernel requires to work properly.

nagal Posted December 20, 2006 Share Posted December 20, 2006 I dont have much to report at the moment because I finally (last night) got the majority of my cooling problems settled with my Xeon 3060 (basically a E6600). Once I find a stable OC in windows (previous tests showed 3.6 not to be an issue) I will be installing OS X. Then I will be able to report back with whatever I find out.

Thade Posted December 21, 2006 Share Posted December 21, 2006 (edited) I can't speak for my Conroe setup. I have not done the mod on my Bad Axe so I max out at 3.2 GHZ with no probs. For pure MHZ in general, my pentium D was chuggin' along at 4.05 GHZ no prob.

Kaspers Posted December 21, 2006 Share Posted December 21, 2006 The DaemonES kernel also automatically detects FSB speed for correct timing. Semthex can also do that.

DaemonES Posted January 11, 2007 Share Posted January 11, 2007 bofors yes you are right, Windows is much more stable, than OSX, even w/o overclocking. I know that, cause I have a lot of experience of iokit programming. This is not an issue, this is a payment for OSX speed. Kaspers yes, but pm timer is much more accurate, than semthex method, just my two cents.

Hi Daemon, Thanks for confirming my suspicions about OS X versus Windows in terms of overclocking.

mdg Posted February 7, 2007 Share Posted February 7, 2007 I have BadAxe2 & E6600: I've been playing around with different versions of BadAxe2 Bios to see how high I can go on air cooling. The 11/17 got me the highest, 4Ghz, but the CPU fan was like a 747 turbine and under no load it quickly got to 59 Celcius (with case closed). I don't know how stable it would be, but I didn't want to wait around and watch my CPU fry. I think that 3.6 is probably a good mix of performance versus risk. This might seem odd, but I was never actually able to hit a stable 3.6 until the new Bios. 3.4 was my max on 11/17, and then 4 G also, but nothing in betwen / very bizzare). The new Bios dated 1/23 (just flashed last night) gave me a nice / steady 3.6 steady on air cooling with a loaded temp around 53'ish and no-load temp in high 40's. / 51. I'm half tempted to get a watercooling rig and see how far this can go...I know I can post/boot in both PC/Mac @ 4Ghz with an older Bios...question is how do I cool this silly thing long enough to run some tests?

Ferret-Simpson Posted February 7, 2007 Share Posted February 7, 2007 Why stop at watercooling? Get a little bit of tooling done and set up a Liquid N2 system! if a 1.x P4 can hit 6GHZ, who knows what the newer chips and Core's can do!?

mdg Posted February 12, 2007 Share Posted February 12, 2007 Here's an interesting discovery, so thought I'd post here... I went out an bought a Big Typhoon...dropped it in and temps went down like 20 degrees (sick!). I was operating at 3.6 Ghz at around 31 C. Put the case door back on, temps went up to 44 C. I have a Sonata II case, and some high end cooling (Seasonic 600W M12, Noctua Fans, Big Typhoon, etc.), and I realize now that this case is a P.O.S. The ventilation must really stink! So, I now realize in order for me to get stable up to 4 Ghz (on E6600) and beyond, I should do testing with my case door open. Run both Windoze and Mac torture tests on the PCS, and once stable, go out an by a "real" case! I have (well, my HTPC I built) a Lian Li case (the G5 look-alike) and it is whisper quiet and incredibly well ventilated. For my personal Hackintosh, I should've gotten another one instead of spending time/money on the stupid Sonata II. For a high end case, it is incredible how poorly ventilated it is in contrast to the door open. Running SuperPi 32M my temps shot up by as much as 17 degrees, and only came off (once complete) about 5 degrees, meaning, the case doesn't ventilate the hot air out. Thought it would be worth mentioning...I think now I can get stable much higher on Air cooling with my case door open, because my CPU is running at like 31 C (+/- 4 for load).
