otterpop Posted July 29, 2009 Share Posted July 29, 2009 Is it possible to determine if I overclocked my CPU in Leopard? I am running OSX 10.5.7 on an Intel E5200 and a Gigabyte GA-G31M-ES2L and have everything running smoothly. The E5200 runs @ 2.5 GHz stock and I am trying to OC it to 3.0 GHz. I have changed my BIOS settings to run @ 3.0 (see settings below) and everything boots up and Leopard loads properly. I have noticed no problems. My question is, how do I know that the E5200 is successfully running at 3.0 GHz in Leopard (or other means)? I have even gone to the lengths of installing VMware Fusion and running CPU-Z to get info and it says the E5200 is running @ 2.5 GHz (as does "About This Mac"). Also, I have read that the E5200 is very easy to OC. Is there some sort of start-up program I can run that I can boot from (similar to how MemTest works) to give me the answer? Here are my OC'd BIOS settings: Robust Graphics Booster - [Auto] CPU Clock Ratio - [12X] Fine CPU Clock Ratio - [+0.5] CPU Frequency 3.00 GHz (240x12.5) CPU Host Clock Control - [Enabled] CPU Host Frequency - [240] PCI Express Frequency - [Auto] Performance Enhance - [standard] System Memory Multiplier (SPD) - [3.33] Memory Frequency 800 800 System Voltage Control - [Manual] DDR2 OverVoltage Control - [Normal] FSB OverVoltage Control - [Normal] CPU Voltage Control - [1.18125V] Normal CPU Vcore 1.27500V Thanks for any suggestions!

broken Posted July 29, 2009 Share Posted July 29, 2009 You can run CPU-X in OS X. Its similiar to CPU-Z and should be able to identify both the cpu and speed. I had an e5200 in my last box and was amazed at the performance for the $. I ran mine at 3.33 GHz (I think) with an aftermarket cpu cooler. http://netkas.org/?p=72 But, you might want to also try to load the CPU to 100% to test stability. I have used Mprime (version of Prime 95) with great success. It can max out all the cores and you can keep an eye on the temps to make sure everything is looking ok. http://www.mersenne.org/ Also, while OCing you might want to make sure you keep an eye on the cpu temps to make sure they aren't getting too hot. http://www.versiontracker.com/dyn/moreinfo/macosx/19994 or http://www.versiontracker.com/dyn/moreinfo/macosx/24043 Good luck!

otterpop Posted July 30, 2009 Author Share Posted July 30, 2009 Thanks broken for pointing me in the right direction. I tried CPU-Z and it tells me that I am running at 2.5 even though I have my BIOS settings set for 3.0. No matter what change I make in the BIOS to the CPU Host Frequency, CPU-Z will always report the Core Speed based on the stock speed of the E5200 (200MHz; stock is 12.5 x 200 = 2.5). It's as if OSX doesn't detect that the CPU Host Frequency being changed; it will always detect it as being 200. If I change the CPU Clock Ratio value, CPU-Z will detect that, but again, it reports the Core Speed as being the Clock Ratio x 200 (even though my CPU Host Frequency is set at 240). ANy other suggestions? Thanks again for your help! You can run CPU-X in OS X. Its similiar to CPU-Z and should be able to identify both the cpu and speed.

otterpop Posted July 30, 2009 Author Share Posted July 30, 2009 After reading all day... I did a CMOS reset and started all over. After trying various settings and being unable to boot past the stock 2.5, I came across a suggestion to try the below BIOS settings and they WORKED! Everything now shows that I am running at 3.0 GHz (CPU-Z, "About This Mac", etc...). I am currently checking temps and getting ready to do the stress test... CPU Clock Ratio - [9 X] Fine CPU Clock Ratio - [0.0] CPU Frequency 3.00 GHz (333x9) CPU Host Clock Control - [Enabled] CPU Host Frequency - [333] PCI Express Frequency - [Auto] Performance Enhance - [standard] System Memory Multiplier (SPD) - [2.66] Memory Frequency 800 889 System Voltage Control - [Manual] DDR2 OverVoltage Control - [Normal] FSB OverVoltage Control - [Normal] CPU Voltage Control - [1.12500V] Normal CPU Vcore 1.27500V Link to comment https://www.insanelymac.com/forum/topic/177152-can-i-check-successful-oc-in-osx/#findComment-1212652 Share on other sites More sharing options...

Look forward to hearing about your results with the e5200. I use to run one on a GIGABYTE GA-EP45-UD3P board and the highest I was ever able to run it comfortably was around 3.7 GHz. But that was with a Xigmatek HDT-S1283 heatsink and fan. Typically kept it around 3.5 GHz or so. I run a Q8200 quad on my GA-G31M-ES2L and I am pretty sure there is no way the Xigmatek would fit on this board with out blocking at least one dimm socket. Though I am running a OCZ Vanquisher HSF and it does a good job of keeping the Quad cool and I don't lose a dimm socket.
