How to solve WHEA 19?

post #1 of 16
Thread Starter 
I have a 24 Hour Prime stable OC at 1.320v but I'm getting WHEA 19 Errors every now and then and always when rendering with Sony Vegas Pro.

I've bumped my voltage to 1.340 and I'm still getting WHEA 19 Errors... am I doing something wrong or should I continue bumping the voltage?

EDIT: Also Vegas always crashes when I try to render so the WHEA errors could be causing it crash.

When I had similar problems, things were fixed for me after adding those 0.02V you already added. frown.gif

I remember I checked the Event Viewer at the end of each day, then added 0.005V if WHEA warnings had been recorded on that day. I did this for about a week. It took around four steps, so those 0.02V, until things were fixed.

Remove you overclock and see if you get it as well. If you dont get any while at stock then its your overclock. If you do then its something else most likely.

Reporting back with the same 1.340 increase and the WHEA errors while rendering with Vegas did reduce and it rendered further than before... maybe I need just a bit more?

Right now, I'd try to fix it with just more voltage. Then for the future, I think playing around with a different LLC setting while using prime95 would be the more correct solution for a problem like this. There might be an LLC setting where testing with prime95 would be a good sign that everything's also stable for normal programs.

Like, you still know the Vcore that was used while prime95 was running for 24h, right? If you set LLC to be less aggressive, voltage under high power use when prime95 is running will drop, and then you need to raise voltage by the amount it drops. You will then keep the same Vcore for prime95, but the voltage for normal programs would be increased and that would hopefully be good for no WHEA warnings and no program crashes.

I've found the most Accurate LLC level on my board already that accurately jumps in 5mv increments and I've tested this using a DMM.

I don't get what you said on the second part though.

The second part was for offset overclocking. It is not interesting if you do fixed voltage and tested LLC with DMM.

I thought you might be doing offset overclocking and that's why prime95 ran fine but normal programs still crash.

When you do overclocking with offset voltage instead of a fixed voltage, the VID voltage the CPU asks for is highest while prime95 is running. The offset and LLC gets added on top of the VID by the board, and that's Vcore. You are then running a prime95 test with the highest voltage your CPU will ever see. The CPU will ask for lower voltage while normal programs are running. This can then sabotage the prime95 testing because it will not be proof that the CPU is stable at the lower voltage that normal programs will see. This can be tweaked by using the LLC. You can use LLC to make voltage drop while prime95 is testing, so that it uses the same voltage as what normal programs will see.

Okay did a quick test and I see 1.347 when running Prime 95 Small FFT but only see 1.330 when running Vegas.

So you're telling me I should increase the offset and decrease Turbo voltage until the Voltage Vegas is using and the Voltage Prime is using is the same?

I understood things like this:

Because you have tested LLC perfectly with your DMM, you can think of it as zero influence, so it can be ignored when thinking about voltage.

The Vcore then is basically:

Vcore = VID + Offset

That should be it. VID is not a real voltage. It is a message that the CPU sends to the outside to the board. You can see VID in the program HWINFO. After you get HWINFO and look at VID, you should see that VID is 0.015V higher in prime95 compared to Vegas.

I don't know how Turbo voltage works on ASRock. The other manufacturers don't have it. They have only Offset. I was believing that the ASRock Turbo thingy is basically the same as Offset, except just for your overclock speeds. The speeds like 1600 MHz and 3400 MHz will not get voltage added. Offset adds voltage to everything. If it's like this, it seems basically like a better version than Offset, and I would not use Offset for anything, only Turbo.

What you can do then is increase Turbo or Offset by the amount that makes Vegas run at the same Vcore that you've seen in your prime95 24h test. It should make Vegas run stable.

After you have done that, you can try to play with LLC. You can use LLC to decrease the voltage for prime95 tests. This will be a bit weird because Vcore for Vegas might also go down a little, so you will have to tweak both Turbo/Offset and LLC at the same time.

The rules for LLC are that the drop is getting larger the more power the CPU uses. The highest power use is in IBT and prime95 small-FFT, then normal prime95, and then Vegas rendering will use less. The drop is then largest for IBT and for prime95 and is smaller for Vegas.

AsRock Z77 boards are known to have horrible LLC and IIRC I'm currently using Level 2 which doesn't go overboard on Voltage but also not too low. Opps sorry it's not the LLC it's just the Voltage reporting in the OS. That's why I started measuring with a DMM in the first place when I started doing my Overclock before.

My 24 Hour prime stable settings were +5 Offset and +27 Turbo and when running Prime 95 the VID is about 1.330V +/- 5mv and the DMM shows me 1.330V so that's why I decided to stay on that specific LLC.

I've added 20mV to my Offset and now Prime 95 runs to 1.350 and if what my DMM and VID was showing me is right ( It was 20mV below 1.330 ) Vegas should run at exactly the same Voltage as I did my 24 hour Prime 95 Stable test.
