I use an Ivy Bridge @ 4.5ghz at 1.25v under load.. I am not sure what to make of Aida 5.01 64??

What test did you use in Prime95?

8 hours means that you only got through the first 8 hours worth of FFTs, however many that amounts to actually being. I know that it's 15 minutes per FFT, but it's not precisely that. So, 30 minutes doesn't mean 2 FFTs. It takes a little longer than 35 to finish two. So, 8 hours is maybe the first 20-25 FFTs, and there are a total of 82.

But Here is what I ran on P95:

1. Prime 95 v27.9 Build 1

2. MAX FFT Size (in K) 1792

3. Memory to use 8192mb

4. Titme to run each FFT Size 5 minutes..

#2 is the problem. You can't just run the 1792K FFT, or limit Prime95 to the 1792K FFT instead of the default of 4096. It's far better to run the default Blend test, or better yet, the Custom Blend test (select Custom while Blend is selected). Then, just enter about 80-85% of your installed memory instead of 50%. That would be precisely 13107 - 19275 MB. Or, 13000 - 19000 if you want to round it just for the heck of it. If you want to use 85% or higher, then, I recommend doing so on a fresh boot with the "Windows Classic" theme selectedOriginally Posted byThe_Nephilim

Well I only mentioned P95 as an example of one of the more stressfult tests I passed.. I am trying to find out why X264 v5.01 BSOD after 10% complete on Aida64 5.01..

I made a mistake the Program I am using is X264 v5.01 the Video Encoder Program NOT Aida 64..

It's best to leave the setting alone that says "Time to run each FFT size" because 15 minutes is far better than just 5. There's no real good need to shorten this time. I mean, there really aren't any valid shortcuts in stress testing.

So, the goal is to try to get your system so stable that it can run this test for 24 hours. Why 24? Because there are 82 FFTs in total and it takes about 24 hours to get through all of them. I know, 82 x 15 is 1,230 minutes which is 20.5 hours, but you will notice that it takes longer than 15 minutes to do each FFT size and it adds up to being roughly 24 hours to get through all 82 of them one time each. I don't know why, but that's just the way it is.

So, some people reading this might ask me, "well, why the Blend test? Look at what it says about the Large FFTs or the Small FFTs" The answer is, for these CPUs like Sandy Bridge, Ivy Bridge, etc., we need something that will stress both the IMC and the CPU cores at the same time (the IMC is the Integrated Memory Controller). So, reader, if you have an older generation CPU like say a Core2, then use the Small FFTs test because that CPU generation doesn't have an IMC and therefore the Blend test is less stressful for your CPU. I'm not 100% sure, but I

Anyway The_Nephilim, let me know how this goes!

While I very much appreciate your Input and help but you have missed my OP completely.. I am NOT having any problems running Prime 95..

I am trying to use x264 v5.01 the Video encoder software.. It has a built in stress test that has real world stress levels.. I run the first test fine it is when it gets to the 2nd test after 10% complete I BSOD..

So Please FORGET about Prime 95 that is Fine.. I need help with why x264 is BSOD on me??

Ever tried Intel burn test on very high?

I think the system is unstable because of the 4 sticks of ram?? I am going to try and run memtest again which I did the other week and it passed fine.. I am unsure what is going on here..

But perhaps the system is unstable with 4 sticks of RAM??

It could be that some voltage needs to be adjusted, but what voltage, I don't know.Originally Posted byThe_Nephilim

OK I think I narrowed down my troubles.. It seems when I run 4 sticks of RAM I get a lot of Freezes.. I just took out 2 sticks and ran IBT on High and it passed when before it would freeze..

I tried bumping up the CPU volts that didn't seem to help.. I don't think I would want to up the voltage on the ram??

For example: I had to increase the VCCIO voltage. You don't have that in your BIOS, but it's the voltage for the IMC. It could be in your BIOS under a completely different name for all I know. I'm not saying that this is it, but the CPU core voltage is definitely not one that you would have to increase. Now, I guess that you can try to increase the memory voltage or maybe some others, but what if you could just wait for some good suggestions and do a lot less work?

I am clocked to 4.3ghz @ 1.210vcore under load.. seems I can go look at the Ivy Bridge guide again and see what else I can adjust..

I'm glad I changed 4x4 16 gb to 8x2 16gb, I may attempt 4.7 GHz again.

I also got it stale at 4.3ghz currently.. I was able to complete a run on the x264 program.. I will have to tinker with this tomorrow off to a gaming session know..
