Hello,

I have a custom build PC I have been suing for about 6 months now. Unfortunately, despite my continued efforts on my own to get my system to overclock, I cannot succeed in making it work.

I have boosted my 3.5ghz to different levels including a 39x100MHz (3.9) and as high as 42x100MHz (4.2). Upon saving, there is no recognition of a speed increase and no improvements with benchmarks or under normal use.

I have also set up the BIOS to be ready for "extreme" workloads, but, alas, still no luck.

I am hoping that someone might have some suggestions as after a lot of searching, I have still yet to find anything that would help.

The full build is as follows:
Intel Core i7-3770K Ivy Bridge 3.5GHz (3.9GHz Turbo) (Over-clock goal is to 4.3-4.5GHz)
NVIDIA GeForce GTX 660 Ti 2048MB
GIGABYTE GA-Z77X-UD5H LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
32 GB RAM 1333MHz DDR3 RAM
Running OSX 10.8.4
Samsung CD/DVD Burn Drive (CDDVDW SH-224BB)
SATA Card Reader
Dual ASUS 1920x1080 Displays (21'')

In addition I have a SSD Main Drive and an additional 6 Internal Drives

hmm, have you modded the BIOS in any way for OS X? i do remember some hackintosh users stating they were able to overclock but, i didn't see many (could be just the fact there aren't many hackintosh users). your best bet will probably be posting on one of the hackintosh forums like www.tonymacx86.com.

I can certainly look into posting there, but I wasn't aware that there would be a difference for overclocking when using OSX? I would have expected the processor to have been independent?

Thanks!

i thought so too :??: but, i'm not too experienced with hackintosh so the problem may lie elsewhere, such as an older BIOS version.

i attempted getting OS X installed on to my PC but, gave up when kernel "panics" (i think it's called a kernel panic?). i'll have a skim around the forums and see if i can find any similar issues regarding this. :)

in the meantime, if you do the same, we can help speed up the process. post back if you end up finding something and i'll do the same.

ok, so your BIOS also shows the stock speeds when you've manually set the overclock higher correct? (Under the M.I.T. section i believe).

if the BIOS also shows stock speeds, what's your BIOS version? (should be labeled F"x" so something like F15 for example).

So you totally lost me, I think the answer is F14, but I figured the easiest thing to do might be to just post the photos of what I have/see.

So here we go:

hmm, it seems like the overclock is working. when you see your clock speeds in OS X and it doesn't show 4.2GHz and rather see the speeds jump around lower than specified speeds it's probably because the CPU doesn't need to use the overclocked speeds. this is caused by something called Intel Speedstep/EIST which helps to save power during light-loading/idle conditions.

however, once your CPU is under heavy load, you should see the CPU's speed pegged @ 4.2GHz as you've specified; so, if you see your CPU's speed not pegged @ 4.2GHz when you're not running any programs/games, this is normal. if your CPU is under a decent/intense amount of load, you should definitely see your CPU hitting 4.2GHz (although you may see your speed not pegged @ 4.2GHz, it's a possibility that you'll see the speed jump to 4.2GHz for a brief moment and bring itself back down which is also normal).

i dont know if there are stress tests compatible with Mac OS X but, if there is, running a stress test and watching your speeds would be one sure way of verifying that your overclock is working.

So I ran a stress test called CPUTest, everything passed, but it gave me absolutely no information as to the speed of my drive. Or at least not that I am aware of.

Running the primenent I got this as the result:
1 : 1 Selftest 6 (256 K FFT-runlength). 100 iterations for M4816897...
1 : 1 Selftest 6 success!

The "enourmous" test gave a similar result:

In both cases however, my computer was still fully functional and felt no change in lag of anything. I also am able to render and export 4K video footage from a film I am working for with similar results.
1 : 1 Selftest 26 (4096 K FFT-runlength). 100 iterations for M69730303...

1 : 1 Selftest 31 (8192 K FFT-runlength). 100 iterations for M145000033...
1 : 1 Selftest 31 success!

So not sure if those tests tell us anything?
