Overclocking on the MSI P67A-GD65 (B3)


Recommended Posts

Note: I'm trying out new things for stability, so I'll be editing this frequently. Scroll to the bottom if you want to find the good stable settings to use.

 

In comparison, overclocking on the ASUS P8P67 Deluxe was a breeze. However, for $80 less, the MSI P67A-GD65 brings a lot to the table. However, I'm not going to go in depth with a review, but am going to share my findings.

 

There's been many known issues in forums regarding the 0x0000124 Blue Screen of Death issue attributed to high voltages for overclocks not being met for idle sessions. I experienced this problem, and spent many hours trying to figure it out. So far I'm lucky, as none of the forums have seemed to have an answer besides a few at the MSI forums. What happens is, even though the system may be stable running Prime95 Blend tests, when you are running the system with the CPU idle and then decide to do a simple task like open a web browser, you get the BSOD. It makes it difficult to troubleshoot, since it's pretty random.

 

My goal was trying to attain a stable 4.6GHz overclock. In comparison, I was able to reach a stable 4.6GHz on the ASUS P8P67 Deluxe at a +.005 offset in the BIOS, with Vcore fluctuation readings in CPU-Z from 1.360V - 1.368V.

 

Initial Failed Attempts due to idle BSOD issue

 

First off, I updated the BIOS to version 1.9.

I then ran CHKDSK on my SSD.

I then booted into Windows and reboot.

I then booted into Windows and installed all the drivers found here: http://www.msi.com/product/mb/P67A-GD65--B3-.html.

My latest Intel Matrix Storage Manager Driver Version 10.1.0.1008 was not able to be installed, there was an error. Therefore, I had to settle for version 8.9.0.1023.

I then re-installed my graphic drivers.

Once all my drivers and software was updated, I rebooted and began to set my overclock settings.

 

In the UEFI BIOS, I went to Green Power and Disabled EuP 2013, CPU Phase Control, and C1E Support (due to issue of voltage not dropping when idle/low load).

Finally, I started my overclock. This was my final settings for a stable 4.6GHz overclock. There's high CPU Core Voltage mainly due to the idle BSOD issue. Notice the higher Current CPU Core Voltage, lower Current DRAM Voltage, and lower Current SA Voltage.

I then set my Advanced DRAM Timings.

Then I finish my setup by going into CPU Features.

Enable Execute Disable Bit, and I enable Intel Virtualization Tech only because I use Windows Virtual PC (most of you probably don't). Pretty much everything else is Disabled besides Hyper-Threading.

So, the end result? Still BSOD during idle! I also had to set the CPU Core Voltage in the BIOS to 1.375V, with Vcore fluctuation readings in CPU-Z from 1.376V - 1.434V, which is really high. However, my watercooling can handle the temps, so I'm not too worried.

 

For 4.5GHz, I set my BIOS CPU Core Voltage to 1.360V.

For 4.4GHz, I set my BIOS CPU Core Voltage to 1.295V.

 

Hopefully there's a BIOS update soon that will handle the lower and upper extreme voltage fluctuations.

 

Latest Successful Attempts using Speedstep Turbo overclocking

I updated the BIOS to version 1.10.B6.

 

In the UEFI BIOS, I went to Green Power and Disabled EuP 2013, CPU Phase Control, and C1E Support, but left Intel C-State on Enabled, and Package C State limit to No Limit.

This time, I left Internal PLL Overvoltage on, EIST Enabled, and Intel Turbo Boost on. I also left my Adjust CPU Ratio to default.

post-70939-13019696027618_thumb.jpg

 

I then set my Advanced DRAM Timings.

post-70939-13018622516527_thumb.jpg

 

Inside CPU Features, Enable Execute Disable Bit, and I enable Intel Virtualization Tech only because I use Windows Virtual PC (most of you probably don't). I then change the Long and Short duration power limits and change the Core Ratio Limit to 46.

Note that using Auto CPU Voltage and SVID for CPU Phase Control allows lower idle voltages, but higher load voltages than if they were manually set. For people who actually use their computers when it's on, it's better to manually set the voltages. When you're on the computer, you're not going to be idle, are you?

 

At any rate, I will update to see if these settings don't BSOD when idle.

 

Note: My RAID 10 array is slower than on a LGA 1366 or AM3 motherboard. It gets around 140MB/sec Sequential Read/Writes as opposed to 220MB/sec Sequential Read/Writes. There's also an error when trying to install the latest Intel Matrix Storage Manager Driver Version 10.1.0.1008. It works with Version 8.9.0.1023.

 

Also, I see in CPU-Z reading when idle, Core Voltage dipping lower than what the BIOS Core Voltage is set at. I wonder if this is what happens when not using Speedstep Turbo overclocking, during idle sessions, why it's causing BSOD's.

 

Update: It keeps doing the BSOD no matter what settings, even at stock settings! I think I may have gotten a bad motherboard. Sending it back for a refund... too much of a headache.

This is interesting, my buddies currently getting bsod's at 4.5ghz @ 1.33v. So raising the vcore stopped them??

 

he got a 0x0000001E bsod while browsing the internet. Prime95 doesn't crash or have any errors.

 

why would the computer need more voltage at idle, that doesn't make sense. (and sounds like vdroop would actually be a good thing here??)

 

he has the P67A-G45 btw

Why are you disabling CPU phase control and C1E?

There's currently an issue even if I leave them on (APS or Intel SVID), the CPU Voltage will be the same, but the CPU will just be downclocked to 1.6GHz at idle or low load. Until it's fixed, I'm just disabling them.

..but the CPU will just be downclocked to 1.6GHz at idle or low load.

 

Maybe I'm confused, but that's what C1E is supposed to do isn't it?

(i.e. Dropping frequency and voltage when idle / at low load, then bumping them up when load increases).

 

Or is there some other issue that I'm not grasping?

Correct, but the issue is that the voltages should be dropping as well, but they're not. It's been a known issue, but the current BIOS beta version doesn't seem to fix the issue.

Interesting I did not see that when I tested. So what you are saying is that the load and idle voltage is staying the same. The CPU is supposed to downclock in no load situations.

Well, I finally updated my findings. Essentially, you can have voltages drop, but you have to set your CPU Core Voltage to Auto, and change the CPU Phase Control to SVID. However, it increases the load Core Voltages more than it needs to.
