CPU: i7-4930k
GPU: GTX 760
MOBO: Asus P9X79
Cooling: Corsair H80i
RAM: Corsair Vengeance 64GB 1866 MHZ
OS: Windows 7 64bit

First time posting here, since I'm at the end of my rope.

I installed a new proc a few months ago and had it overclocked to 4.2ghz, using the Turbo features in the BIOS, and it worked great until now. Last week I got successive BSOD while rendering in Nuke with temp spikes at 81c. Temps were at 40c at idle and would shoot up to 75c after a few seconds of rendering and then to 80c. When that happened I would stop the render.

I don't know alot about overclocking, that's why I went with the auto features in the BIOS.

I reset the overclock back to optimal, and no more BSOD, but now I'm getting lags while just working where the proc spikes at 100%.

I checked the dump logs and it was the hal.dll x124 error on the BSOD. Which seems like it was due to overheating or some other failure with the cpu.

After doing my research, I'm going to redo the thermal paste, to see if that helps.

What I'm wondering is, is there any other test I can do to see if it is a fried CPU? I've tested it with intel's cpu utility and it passes fine. I want to make sure I rule out any possible setting before having to head to ebay to try and find a new proc.

Thanks
Nick

Check your processors rendering performance at stock settings with a benchmark such as Cinebench. If you get a normal result, then your CPU is still OK
Don't use any overclocking utility - it tends to cause high temperatures. Instead, here is a very simple and conservative approach to manual overclocking
1. Use CPU-Z to find out you Vcore at stock settings.
2. In BIOS, set Vcore to 0.1V higher than stock
3. Increase your CPU speed to 4GHz, and use your PC as normal. If it crashes, change it to 3.9Ghz in the BIOS and try again. If it doesn't crash try 4.1Ghz etc

The hall.dll.

Is to do with the graphics Api you are using to render the image in the rendering program.

You have the Direct X api, and an Opengl Api renderer.

If the system has slowed down.
it`s due to this.

It will be related to the graphics driver for your GTX 760 card.
And if you are using hardware rendering or Gpu rendering.

The slowdown would therefore be to do in some part with the Graphics card.

Gpu getting hot also, and downclocking in speed to cope with heat.

As much as when you use the Cpu for rendering images as rendering puts a heavy load on both.

Often to resolve it, you may have to un install the video driver then re install it to re set the settings or parameters.

Thanks so much for the quick reply. I haven't replaced the thermal paste yet, but I did run some tests in cinebench. I was getting 778cb/115cb which is much lower than the other 4930k I saw on the list. Granted some of them were overclocked, but it is lower. I'm going to double check the bios again and make sure all the settings are stock.

I've updated the GPU drivers, and it seemed like things were working much better until this evening when I'm getting the processor spikes again. When they happen the core voltage goes up from around .98 to 1.08 and holds rather than fluctuates like normal.

Also when this happens the cpu temp jumps from 26c to 34c.

After it hangs for a few seconds everything drops back down.

Still haven't replaced the thermal paste, but I think I will have to at this point since the problem is still persisting.

Does this extra information point to anything in particular?

I tried cinebench right now and it seemed like it was working ok, but my current Nuke render went from 2.5 minutes early this afternoon to potentially 20+ minutes.

Lastly during this render I saw my cpu frequency drop down to 1200 mhz while it's sitting in the cpu spike, although now it's back up to 3600 mhz.

Thanks again for any advice. Really frustrated with this.

I replaced the thermal paste, and no change.

After trying that, I just swapped out a new processor (same model), and for about 5 minutes it seemed like it was working much better, but then the processor spikes started again.

I tried another graphics card, with no change.

Could it be the motherboard at this point?
