So I should put my turbo boost up 2 steps and my multiplier 1?
Because it seems to me that only adds voltage when I'm under load and it craps out on me when starting windows which won't really put that much load on it or does it?

Thanks for your help!


Offset increases/decreases your idle and full load voltage. Addition Turbo voltage adds to the full load voltage provided by the current offset. Turbo increase your full load without having to change your offset, this help you to maintain a low idle voltage.

Do you have your power settings in windows set to balanced? Your multi in CPU-z should decrease to 16 at idle.

Set your multi to 46, your offset to +0.005 and your turbo to higher then +0.012. Then run P95, if it fails increase turbo and run P95 again. I would recommend running P95 for over 6 hours other members will recommend 24 hours.

Ok. I have read this guide and looked at the images a dozen times over the last week and have just recently started trying to overclock my 3750k. So far my only question is that in the guide it talks about the CPU Load-Line Calibration and how you should pick the level that makes CPU-Z read closest to the BIOS Vcore.

Except that I am not sure where I can find the Vcore usage in the UEFI. Unless that is what CPU PLL is(My guts says no on this, mainly because the guide says this is only of the options to change to help with overclocking..). Since I can't seem to find it at the moment I have stopped overclocking at the moment.

So could someone please help me find where the Vcore usage is in the UEFI/BIOS?

CPU voltage should be one of the first options in the voltage section of bios. Should be option for Manual/offset and CPU voltage should be under it.

Using the example image in the voltage section in the OP... My UEFI gives me the same options, but I was under the impression that that page would also show me exactly how high the vcore usage is/was.

It should be displayed under the H/W tab in bios. Unfortunately with the newer bios it doesn't display correctly IMO. In mine it shows slightly above 1.00v which is closer to my idle vcore then my full load. My older bios would display the full load.

I thought the H/W monitor had it, but like your system it stayed around 1.00v so I considered it to be the voltage when the system was idle and attempted to see if I could find what the last max volt usage was in the UEFI... and failed for a good reason.

Well, I guess that means I will have to trust that CPUID Hardware Monitor and CPU-Z are showing the correct voltage. I stuck to level 2 because it caused less fluctuation in Vcore.

I will just have to proceed carefully. I hope I can get a decent overclock.
post #6587 of 9601
Yes just pay close attention to the voltage in CPU-z and your temps

Edit: Nvm, it looks like upping turbo boost by 1 did it. Now all I have to do is see if I can reach 5ghz... probably not lol.(If I can then biggrin.gif but if I don't make it I'll still be happy staying at 4.5 tongue.gif Besides, it would be interesting to see how close I can get.).

Do you have your power settings in windows set to balanced? Your multi in CPU-z should decrease to 16 at idle.

Set your multi to 46, your offset to +0.005 and your turbo to higher then +0.012. Then run P95, if it fails increase turbo and run P95 again. I would recommend running P95 for over 6 hours other members will recommend 24 hours.

My power settings are set to high performance, should it be on balanced?

And I can increase turbo voltage aslong as I my core voltage doesn't exceed 1,5 V, and around 90 degrees right?

Yes you want your power settings on balanced otherwise the CPU will not downclock at idle. I dont know what type of cooling you have but you will probably hit your max temp before hitting 1.5v but yes keep increasing turbo.
