yeah, I totally missed the actual timing graphic. My bad.

Have to blame this one on the The TechGuyMax. :-)

I am certainly learning a lot from this experience. I tried an OC of 4.5ghz and got a BSD. Tried an OC of 4.4ghz and got BSD during final on approach to KSFO in the PMDG 738. I was able to complete a flight at KSFO in the 738 at 4.3ghz. I have set a XMP profile for the 2133. CPU-Z is still giving me the same readings as above so it is probable that the RAM was in fact damaged when it crashed.

I think my options are to stay with the GTX 960 or up date the whole computer to utilize the GTX 1080. We will see what "she who controls the checkbook and pays the bills". has to say.

Thank you all from your help and encouragement.

Hi Greg,

I have been following this topic with great interest.

The reason you experienced a BSD is because your OC was unstable, when you OC any CPU you need also to alter your CPU voltage in order to allow the CPU to have more power and keep things stable, however the more voltage you add the hotter the CPU will run, so the trick is to find the sweet spot between the CPU Clock speed, the CPU temp and the CPU stability.

Please read this guide which will teach you the basics of CPU OC: https://www.techradar.com/how-to/computing/how-to-overclock-your-cpu-1306573

You should aim to keep an OC speed that do not make your CPU hotter than 79c under stress using Prime95, this is for safety reasons and to be sure your CPU don't run too hot. Please feel free to contact me privately with any questions regarding OC, you don't need to switch back your Video Card at this stage, let's focus in getting your CPU OC first and when this is done you can swap your video cards again to give it another go.

I would start OC at 4.4Ghz with the XMP Profile set for you memory, make sure your PC is stable and then try to push for 4.5Ghz since not all CPU's are capable of being stable at 4.5Ghz.

Best of Luck,

Simbol

Greg,

I know what it's like to have to go it alone when working a problem.  Tell you what, I belong to a private flight sim group (all wonderful, friendly people and fairly seasoned).  Should you ever wish to discuss the issue you're having then feel free to drop by our voice (Discord) server. I've sent you the information to join us on the server.

Best wishes.

 

Thanks Dave!

It is this slide (the "Memory" tab) that shows the memory speed... 1068.4 x 2 = 2136.8 MHz.  The other slide(s) (the "SPD" tabs) just show the available JEDEC/XMP profiles. 

Greg... having gone from a 970 to a 1080 myself (on a Haswell system) after moving from FSX to P3Dv4 late last summer, I hope you'll press on with the new video card.  It may take a bit of time and experimenting with different configurations, but the 1080 does quite well with v4.

Good luck,

Greg

Good catch!

I was in fact basing my comments on the SPD tab shown in Greg's most recent post (at the time) and not the memory tab.  

 

Greg: your RAM appears to be fine, though there is definitely more performance to be had by overclocking or replacing your RAM with faster stuff.  Beyond 2133 RAM speed on Haswell the percentage gains begin to fall off though so it's probably not worthwhile at this point given memory prices.  

As for BSODs, is your computer in fact "blue screening" or is it just crashing to the desktop?  If it's actually blue screening, there ought to be a stop code recorded.  See the links in my signature about how to diagnose this and we can figure out precisely why your OC is unstable.  An unstable OC can definitely cause erratic performance so we may just be on to something.

My current GPU is a GTX970.  I also tried an upgrade to a 1080 some ago.  Although I saw some (small) improvements in games and sims OTHER than P3D, my flight sim experience changed not one little bit! I returned the 1080 for refund and continue happily with my 970;-)

You know, I guess I've been blocking it out, but I keep seeing people refer to increased performance when upgrading from a 900 series to a 1000 series GPU.

One really shouldn't expect anything more than very slight performance improvement, if that.  What the 1000 series provides (in P3D) is the ability to use the enhanced lighting and shader features in P3DV4 at about the same frame rates they received with a 900 series card before the P3D enhancements.

 

NickN over at Simforums a few years ago wrote a great guide for overclocking Haswell systems.

Looks very well done and thorough.

HTH,

The cause of the poor frames at Orbx regions and Mega airports has resolved. The issue has to have been caused by installer(me) error.So that we can all learn from this i will share the results of my further investigation.

I talked with Richie at MSI. He did some research and then informed me that an an I7 4770K on a Z87 Pro motherboard would not bottleneck the MSI GTX 1080 Gaming card. He asked me to run a 3dMark bench test. I downloaded 3DMark 11 the free version and ran the bench test first on my GTX 960 and then replaced the GTX 1080 in my machine and bench tested it. Here are the results.

3DMARK 11 PERFORMANCE 1.0

VALID RESULT

SCOREP10 834 with NVIDIA GeForce GTX 960(1x) and Intel Core i7-4770K Processor

Graphics Score

10 919

Physics Score

11 166

Combined Score

9 828

 

 

3DMARK 11 PERFORMANCE 1.0

Physics Score

Combined Score

I then started up P3DV4.2 and ran a test flight using the Milviz Bell 407 at KSFO, KLAX and EDDF. The Orbx regions were installed along with Flightbeam KSFO FSDT KLAX and Aerosoft Professional EDDF. My frames are locked at 30fps. At KSFO and EDDF I got very little frame variation i.e. 30-29-30 fps and very smooth flight. My frames at KLAX varied from 30-20-30 FPS with a slight pause a couple of times. This was the performance I was expecting. The settings were the same as what I used for the GTX 960. I will play with some of the texture and autogen settings and see what happens.

My conclusion is that I probably did not have the GTX 1080 fully seated the first time. I just never thought to try taking the card out and putting it back in. The is the only cause of the bad performance I initially experienced.

Thank you all for the help. I have really learned a lot.

I have specced out a new system on Newegg. I7-8700K, ASUS ROG Maximus X Hero motherboard, G.Skill TridentZ RGB 16GBS DDR4 3600, Cooler Master HAF X High air flow full tower. Windows 10 home on a Samsung 960 EVO M.2 250gb PCI-Express 3.0x4. I will reuse My Corsair 850w modular PSU, Samsung 850 EVO 250 GB SSD, Samsung 850 EVO 1TB SSD, WD 2TB HHD for storage and the new MSI GTX 1080 Gaming GPU. 

Since I have agreement from the keeper of the checkbook, I may just go ahead and update the whole shooting match. I really like how P3DV4.2 performed at 4.4ghz. much better than 4.3ghz. I am sure 4.7ghz will be even better.

Again thanks everybody for the help,

Greg
