  1. Post your Geekbench score

    See below. http://www.insanelymac.com/forum/index.php...st&id=98696 http://www.insanelymac.com/forum/index.php...st&id=98695
  2. I tried 10.6.8 and BEYOND, but both screwed up my underclocking advantages; so I reverted to 10.6.7 on another HD. For me, "AppleIntelCPUPowerManagement: Turbo Ratios 0000" had negative results. This is the edge I got back (1) by downgrading to 10.6.7 on another hard drive so that underclocking ability is fully restored and (2) by increasing the eventual Vcore (to 3.50 for CPU0 and to 3.25 for CPU1) and the BCLK to 182, yielding a maximum turbo boost of 4.914 GHz.
  3. What follows is the only way I know that one can achieve the benefits that I've expounded on from underclocking: I began each of my Gigabyte systems by installing Digital Dreamer's distros, following his every instruction for the version of Snow leopard that I had at that time. See, for example, http://www.insanelymac.com/forum/index. ... pic=185097. Then, I learned about d00d and what he had achieved in improving his systems' performance. So I then made all, not some, of the non-DSDT changes that his guide suggests and downloaded his DSDT.zip that was appropriate for my CPU. After unzipping it, I took the DSDT.dsl file and placed it within the Debug folder within the DSDT_Patcher folder within the ~extra folder within the HackInstaller folder within the Run2MakeHackintoshMacHD folder from Digital Dreamer. Then I ran DD's RUN_HACKINSTALLER.command terminal script, and when prompted entered my system password, selected the drive for installation and ran (by entering the no. 7) Run DSDT Patcher. I then exited the script by entering the no. 20 and returned to the Debug folder and copied my newly minted DSDT.aml file and dropped it in my Extras folder then rebooted. The rest is as I've stated earlier, which is partly based on what I read on posts by Sam Oslo (who had achieved a Geekbench 2 CPU score of 27+ on the EVGA SR-2 mobo with some unusually behaving chips) and Movieman (both on yet another forum - Xstreme systems) about BCLK sweet spots). I followed this same path for my EVGA SR 2, except that I followed all, not some, of d00d's guide for that mobo, even changing my version of Chameleon to the exact version d00d recommends. I used the same process to convert my DSDT.dsl file to my working DSDT.aml file. Any deviation from this path may not yield all/any of the benefits that I have described.
  4. d00d, I'm running 10.6.7. I get six places in kernel.log: Apr 16 00:33:48 localhost kernel[0]: AppleIntelCPUPowerManagement: Turbo Ratios DDDDEE
  5. d00d, As always less is more, making one of the world's slowest 12-core machines one of the fastest. Here are my some of my underclocking results for my 24-7 settings of: 1. No changes in Signal Tweaks yet. 2. No changes in Memory Configuration yet. 3. Frequency/Voltage Control Both CPU's - Without VDroop CPU 0 Vcore boot - 1.2750 CPU 0 Vcore eventual - 1.3000 CPU 1 Vcore boot - 1.2675 CPU 1 Vcore eventual - 1.2875 CPU VTT both boot - 1.325 CPU VTT both eventual - 1.350 CPU 0 DIMM Vcore - 1.65 CPU 1 DIMM Vcore - 1.66 IOH 1.35 Everything else at default or auto for now. 4. Frequency/Voltage Control No Dummy O.C. Target CPU - 2.17 CPU Freq. - 167 PCIE Freq. - 103 CPU Multi - 13 QPI - 4.8 Memory Freq. - 1066 Everything else at default or auto for now. 5. CPU Configuration Everything is Enabled and/or set to Auto, including the newly exposed C1E, except MaxCPUID which is disabled. All else is as you have advised, except that I have moved the MB and all other internals to a easily modified Antec Twelve Hundred case. There are now only 17 internal fans in this puppy, including all the Antec 1200 standard fans and others on various PCIE cards, the CPU cooling systems and the ones I added over the PWM for CPU 0 and the side panel. It's blazing hot in the southern US this summer, so my System temps are in the mid to low 40's C. and cores are in the mid 30's when at idle and range from 45 to 68 when running benchmarks and rendering but quickly drop into the mid to high 30's throughout. But when booting with -v I see that my turbo boosting pay day is DDDDEE. In other words when there is no turbo boost its a 12 core 2.171 GHz cowardly lion; however when I need it to roar, it musters up its core to {Correction - for each CPU} (1) 4.344.4 GHz, 4.344.4 GHz, 4.344.4 GHz, and 4.344.4 GHz, or (2) 4.512 GHz and 4,512 GHz, depending on the environment and the prey. {Addition - So essentially some cores more than double their speed, yielding benching scores about 40% faster than the top-of-the-line mid-2010 machine, for comparably about 80% of the cost and at reasonable voltages.} Below are pics of underclockings' 24-7 yield on the second day of our hot summer.
  6. d00d, I finally figured out that I had to take two tests to post any more because I am a newbie. Here are the picts. But first - a test for other newbie visitors. If you read d00d's posts very carefully, you'll see that he teaches us that less is more. Using conventional wisdom, is a system with lower clocked GHz chips faster than a system with the same number of chips and cores, but higher clocked? In other words, which of the following 12 core systems is fastest at running OSX benchmarks under Geekbench2 and Cinebench 11.5: 1) a 2.930 GHz system, 2) a 2.550 GHz system, 3) a 2.325 GHz system or 4) a 2.230 GHz system? I know that there are some "depends." But if you've got d00d's messages correct, then you'll be on the right track for overclocking (I really mean "underclocking") Westmere's and Nehalem's. If you want a faster mac, then underclock it after you've done as d00d suggests in post #1. If you want an ever faster mac, then underclock it some more. Serious underclockers seek a turbo boost payday. My present 24/7 underclocking achievement is a 12 core 2.230 system that pays me back with a turbo boost ratio of CCCCDD (i.e., 12-12-12-12, 13-13). "So what!", you may say. Since my two processors are the xeon x5680 that run natively at 3.33 GHz and at a x27 top [and most importantly to remember - constant] ratio, whatever number my CPU frequency is (such as 160) gets multiplied by 27 to determine my maximum turbo boost speed. At a CPU frequency of 160, my maximum turbo boost speed is 4.320 GHz (160*27). I can lower the CPU Multiplier setting from its stock maximum of 25 [on my x5680s] (the other 2 digits adding to 27 are there for standard turbo boost) to 13 or 17 or 15 or even 14 [or any other number less than 24 but greater than 12]. The order in which I've listed the CPU multipliers in the previous sentence are starting with the best for my system. Odd numbers yield best results - at least on my system; so your mileage may vary. The maximum turbo boost speed (4.320 GHz) remains the same so long as the CPU frequency (BCLK) setting isn't changed. But as I take that CPU Multiplier lower (dousing a little more BCLK on it as I go lower), my system remains cool and I can use less Vcore. This increases the chances that I'll get all of the available turbo boost when needed. Overall, it also does not put as much stress on my CPUs all of the time. C-states, T-states and all other energy and power management/savers are activated. CPU core temps range from 26 to 33 degrees C while just word processing or surfing this forum to 55 to 64 degrees C when rendering in Cinema 4d. This is how to speed up your system, while prolonging its life and holding on a little longer to that cash your power company wishes you would spend for energy. Show me a faster OSX system (those i7-2600/2400 scores that appear and are routinely removed from and by Geekbench and my posted Geekbench scores, such as the 37837, 37393, etc. don't count) and you will have shown yourself someone else who is a follower of d00d's teachings. Check out the picts below for proof of the truth of d00d's philosophy. To truly get the point, check out the picts in reverse order. On the ostensibly slowest setting, the Geekbench2 score is 33% faster and the Cinebench 11.5 score is 39% faster than on a 2.93 GHz 12-core system. If you use Cinema 4d, a 39% speedup in rendering performance is nothing to sneeze at. Again, thanks d00d for graciously sharing your advice and helping me to get internal audio working. You've truly earned the title "InsanelyMac Sage". P.S. For you dual booters, this is how an underclocked 2.534 GHz setting (2.33 GHz juiced up thru E-Leet with additional BCLK and voltage) stacks up in Windows 7 on Wprime: 1) 5th fastest Xeon x5680 12x H20 Cooled Worldwide 2) 5th fastest Xeon x5680 AnyCore H20 Cooled Worldwide 3) 10th fastest Intel Xeon 12x H20 Cooled Worldwide 4) 10th fastest Intel Xeon AnyCore H20 Cooled Worldwide 5) 10th fastest Intel 12x H20 Cooled Worldwide 6) 10th fastest All 12x H20 Cooled Worldwide 7) 10th fastest Intel AnyCore H20 Cooled Worldwide 8) 15th fastest Xeon x5680 AnyCore AnyCooled Worldwide 9) 15th fastest Xeon x5680 12x AnyCooled Worldwide 10) 22nd fastest Intel Xeon 12x AnyCooled Worldwide 11) 22nd fastest All AnyCore H20 Cooled Worldwide 12) 23rd fastest Intel Xeon 12x _Worldwide 13) 23rd fastest Intel 12x AnyCooled Worldwide 14) 28th fastest Intel Anycore AnyCooled Worldwide 15) 37th fastest Intel AnyCore_Worldwide 16) 49th fastest All AnyCore AnyCooled Worldwide 1) 2nd fastest Xeon X5680 12x H20 Cooled North America 2) 2nd fastest Xeon X5680 AnyCore H20 Cooled North America 3) 5th fastest All 12x H20 Cooled North America 4) 5th fastest Intel Xeon AnyCore H20 Cooled North America 5) 5th fastest Intel 12x H20 Cooled North America 6) 5th fastest Intel Xeon 12x H20 Cooled North America 7) 8th fastest Xeon X5680 12x AnyCooled North America 8) 8th fastest Xeon X5680 AnyCore AnyCooled North America 9) 11th fastest All 12x AnyCooled North America 10) 12th fastest Intel Xeon 12x AnyCooled North America 11) 12th fastest Intel 12x AnyCooled North America 12) 12th fastest Intel Xeon 12x AnyCooled North America 13) 12th fastest All AnyCore H20 Cooled North America 14) 14th fastest Intel AnyCore AnyCooled North America 15) 23rd fastest All AnyCore AnyCooled North America 16) 23rd fastest Intel 12x AnyCooled North America Geekbench 2.1.12 for Windows x86 (64-bit) yields a score of 27,775 and Cinebench 11.5 yields scores of 76 fps and 20.49 for the xCPU. So you see that following d00d's teachings also makes for a not too shabby Windows dual boot system. Is there another Cal Aggie in the house? Do you have an EVGA SR-2? It's a great mobo. However, the same thing can be done with i7-920 & i7-980X systems. I've done it using d00d's quidelines published elsewhere on this forum.
  7. Thanks d00d for graciously sharing your advice. I hope that you have a most happy New Year and continue to shed your light on all of us.
  8. d00d, where and how is the DSDT file/folder placed? Thanks.
