Prepar3D V2.4 on an i7 4770k/GTX 780 system at 5ghz

[Guest]

It that time of the year that I put my system through its paces and OC the CPU to 5ghz, the GTX 780 by a couple of hundred Mhz and get my 2400mhz CL9 to CL8. How do I do this? I put the entire system in natures fridge.   I will point out that I have only done this once before but for a good 6 months so despite the appreciated cautions and warning from people who know far more about computer hardware than I do I am emboldened to do it again!

 

I case you haven't figured out whats about to happen I am going to put my system that cost the best part of $4000 outside in the cold.

 

Anyway I first this last year to put the squeeze on FSX and frankly it worked. All other thing being equal I got a noticeable performance increase over 4.8ghz with a 4.5ghz bus.

 

I am not encouraging anyone to try the same with there hard one Hardware. Its risky and at the voltages that I will be running my Hardware will not last as long as can normally be expected! You have been warned don't try this at home unless you can eat what you spent on the hardware. :excl:

 

More to come later

Interesting. I have the good luck to overclock my i2500k to 4.93GHz and it has been running at that speed since four or five years ago. The sad thing is that after these many years Intel's bleeding edge CPUs are still stuck below 5Ghz.

 

I'm so dreaming for the days of 10GHz CPUs. I believe that's the only way to double my current fps in P3D, and to solve all my concerns on fps once for all....

Are you worried about condensation forming the case and possibly hurting components?

You wont get to 5.0 on the 4770k stable. I'm on the 4790k and can get 4.9 for only about an hr or 2 flight then BSOD! i'm on water (h110i) But of course, every board is different and no CPU is ever identical so you may!

 

It is kick &@($* performance though. Nothing out of this world, I still get a good FPS hit in a rural city with overcast and traffic. My goal is to SLI 2 980s when p3d 2.4x supports SLI!

I hope he haz another puter to tell us he killed his P3D puter with.

How about just installing a custom water loop?  That's what I have and my temps are phenomenal. SLI 780's and cpu in the loop. gpu's OC'd by 300Mhz and 4790K running at 4.7 stable.

for you people running SLI, how much performance gain you have in P3D without using that special SLI mode hack? I'm considering to add a second 780ti since the price now dropped to around $450.

You know for $25 dollars Intel sells over clocking insurance if you burn your CPU up they will send u another.

Thanks a lot!

 

I've duplicated your efforts outside and crashed the perfectly good PMDG 747 due to wing icing…

I see the skeptics are out . Great I love a challenge. You guys are going to be eating your words soon enough .
So the whole point is to examine the effect of Overclocking on P3DV2.4 and see if it makes a worthwhile difference. I’ve read a few posts that suggest it doesn’t make a difference so I want to see for myself and quantify it.

I will get to 5ghz! and I will squeeze every last drop out of the GTX 780 and I will get the DRAM from CL9 to CL8.
Just for starters here is a comparison between an ambient temp of 20c and 10c

At the Stock CPU speed of 3.7ghz (turbo bust I guess is on)
Thermal Radar Inside:

Thermal Radar Outside:

Under Load Inside:

Under Load Outside:

 

And at a CPU speed of 4.6ghz
Thermal Radar Inside:

Thermal Radar Outside:

Under Load Inside:

Under Load Outside:

 

Not the ambient temp difference is 10c.

 

and the Package temperature difference between the inside and outside at 4.6ghz

is 13c.

 

A bit higher but I guess its safe to say that for every degree the Ambient temp drops the Package load temp of the CPU under load will also drop by about the same giving all other things are equal so at 0c the package temp will be 34c or less etc.

 

The benchmarking technique to come next

Thanks for the heads up in that. I emailed intel customer support and asked if the Performance Tuning Protection Plan Covers CPU's that have been delided. I suspect not bu no harm in asking.

 

yea laugh it!

But seriously Dave, here's hoping you're able to pull this off! Looking forward to the performance comparison...

So cool... any screenshots of of in game fps?  Smooth with Orbx, payware orbx, AI traffic and heavy weather?

Here is the method:
Made a short flight with demanding addons and very high setting (just enough to FSUIPC to warn of an impending OOM. I used P3D's Built in recorders to record the flight. Then a system restart to keep everything nice and clinical and played back the recording and recorded the Playback with ShadowPlay also capturing the FPS. I use the Milviz 407, ORBX PNW, FSDreamTeam CYVR and REX4. The weather is also pretty bad.
 
The first playback is at 3.7ghz:
 
Here is the flight:

And here are the results:

 
The next graph will show the FPS at the same intervals on the same playback for 4Ghz.
I am will to beat the graph will look the same but the FPS will be 1 or perhaps 2 FPS higher a the same intervals. Not sure though because I have read posts indicating that overclocking does not benefit V2.
