Solved BSOD when running CPU-Z or HardwareMonitor after overclocking

[Belthasar]

Hello!

I built my PC in November of 2011, and have just now started to overclock the CPU and GPU to maximize my gaming performance. I made the following changes:

CPU Offset Voltage +0.005V
CPU Turbo Boost Voltage +0.004V
CPU Multiplier x34 (Up from 33...just started)

About 50% of the time when I run CPU-Z or HardwareMonitor, my computer crashes, saying:

"A clock interrupt was not received by a second processor within the allocated time interval"

I've attached an export, as requested. This just started to happen when I dialed up the multiplier, and didn't happen when I kept the voltage the same and turned it back down to x33. I've since stopped using HardwareMonitor or CPU-Z to monitor core voltage and temperatures and have successfully ramped the multiplier up to x40 without issues (Prime95 for 20 minutes produces no errors). However, it still sometimes crashes when I run either of the monitoring software applications.

Any ideas would be appreciated. Thanks!

Hi Belthasar.

Do some basic things before starting overclocking.

Update your BIOS to the latest possible.

BiosVersion = P1.10
BiosReleaseDate = 08/30/2011

Get the BIOS version 2.20 dated 6/6/2012 from ASRock > P67 Extreme4 Gen3.

Make it sure that the PSU is supplying adequate power.
Check if the Power Supply Unit (PSU) supplying adequate power to the computer or not.
eXtreme Power Supply Calculator
Also let us know the wattage of the PSU.

Dont let the computer overheat. Is the computer hot? Report us the heat of the computer after a couple of hours of your normal usage. Upload a screenshot of the summery tab of Speccy.

Have you overclocked the Processor?

Stress test the CPU.
Hardware - Stress Test With Prime95

RAM ... 2x4 GB @1600 MHz.
Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.

Stress test the Graphics Card using Furmark.
Video Card - Stress Test with Furmark

Those tests are needed, to ensure that the hardware are in good condition to be overclocked.

Also, you should know that improper overclocking causes BSODs. As you are new in overclocking, I will request our overclocking team to guide you the proper way.

In the mean time you supply the information and the test results those are asked .... those will be helpful in the process.

When you start overclocking, that is usually a sign of too little core voltage, or some other hardware problem. You will never get a stable overclock without using CPUz and a CPU temp monitoring program. Use Core Temp, it gives a good reading on your CPU temps and other things too. Without monitoring programs how will you know if you hit your target speed or are overheating, or if a core shut down? But, first things first. You need to run Prime95 or AIDA64 (not free, but excellent) at stock for 12 hours without overheating. If you are not stable at stock, you will never have a stable overclock no matter what you do. Also run memtest86+ for a minimum of 8 passes (http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html). Also, when running Prime or AIDA, keep a close watch on your CPU temps. They will climb very rapidly. Unless you have a very good after market CPU cooler, you will over heat very quickly. If it gets close to TJ Maxx, stop the test before you get to max temp. But again, you have to use CPUz and temp monitoring programs to overclock. Before overclocking I would do a lot of Googling and reading. You can ruin your CPU or Motherboard if you don't know what you are doing. Also, what brand, wattage, and amps on the +12V is your PSU?

Thanks for your help. Updating the Bios seems to have fixed the issue. I do have some experience overclocking, but was confident that this couldn't possibly be a voltage issue and was confused about a possible cause.

@essenbe, my power supply is a Corsair HX750, which can output 62A on the +12V rail. This should be more than sufficient for anything that I'm planning to do. I'm also using a Corsair H100 water coolor, so I should have good headroom as far as CPU temperature is concerned. I had run Prime95 & Memtest for 24 hours each to test my CPU and RAM at stock when I built this PC, and had no issues with either.

Having (probably) resolved the issue, I've kicked the multiplier up to 44 and have been stably running Prime95 for 30 minutes. Temperatures are well within an acceptable range.

I will run Memtest overnight as a further precaution and will report back.

Just let us know how it goes, and be aware that Sandy Bridge overclocks different than any previous chip. We also have an overclock leader boards on this forum where you can get plenty of help, but you have to be a little crazy to post there. Well, you don't have to be, but it helps. We kid around a lot there, but there is a vast amount of overclocking knowledge represented there. But, you have to watch the temps. I had an H100 and that's why I have custom water cooling now.

But, you have to watch the temps. I had an H100 and that's why I have custom water cooling now.

Out of curiosity, what sort of problems or inadequacies did you find? Is there anything, in particular, that I should watch out for?

 

[essenbe]

It depends on what you do. If you are staying in the normal overclock range, it will do fine. If you want to do some high overclocks, it can't keep up. Depending on your ambient temps, as long as you stay around 4.5, you should be fine. But, when you run Prime, watch it closely. Plus, the stock fans sound like a 747. I changed out the fans to Noctua's and gentile typhoons. They were much quieter and did as good a job. But, no matter what cooler you get, your anbient temps will decide. I live in a very warm climate and it just didn't work for me. Plus, I will on occasion pump some high volts through the chip. More voltage = more heat.

Bookmarked this thread, for this post. Invaluable.

9 hours of Memtest+, no issues. I think this issue is safe to close. Thanks for the BIOS update suggestion and general pointers, all.

 

[essenbe]

I hope things work out well for you. If you need any assistance, we'll be right here. And don't forget about our Ocerclockers Leaderboards. We have fun there. Tou can learn a lot there also.
