If you Over Clock your Processor and get CTDs or Crashes read this

[Chilled Out]

To the point.

I had a CTD last night and for the first time when I looked at the Crash Log i noticed at the very bottom was CPU: 4.8

Ah , no. My Processor is Over Clocked in Bios to 4.7 Ghz. I built my Skylake Machine with an i7 6700k and 32 gig of DDR4 3200 speed Memory.

I ran numorous stress tests on the Processor, Video Cards and Memory. I found that 4.7 Ghz was the absolute limit I could go with out my Computer Crashing a LONG time ago.

So I know factually that if the Processor were to actually run at 4.8 Ghz yes it would crash.

The Question is is the Crash Log accurate in its determination of that Clock Speed? Is DOOM some how able to push the Skylake i7 beyond the Set Clock speed I have in the Bios?

Well I tried to research if Software can Circumvent Clock speeds set in the Bios and could not find a thing. Granted that is an extremely technical question.

I do no this. Crytek always Pushed our Processors to the limit in the Crysis games. Their Engines were more Dependent on the Processor than the Video Cards.

I am inclined to feel the same way here.

What if the people that are getting CTDs are having their Processors Overclocked BEYOND the so called limit we think we are setting in the BIOS.

I have always thought it couldnt be done.

Can it?

Download Afterburner or HWMonitor and keep an eye on your CPU speed.

As I said in your other thread, I believe it is just a reporting error in Doom, but there are hundreds of tools you can use to monitor your CPU to be certain.

If the report is true it means that the game is amazingly optimized since it will take all juice from your machine, I'd be impressed.

I use EVGA Precision. The point is can DOOM push a Skylake i7 beyond its designated Clock? Why would DOOM say its running at 4.8 ghz.

The way Windows 10 works and my hardware, is the Processor Clock only Throttles up to what I thought was its max when it needs too. I have watched it do this in Benchmarks and games where I can use that overlay. The recent version has CPU Clock parameters.

Never the less, I lowered my Clock to 4.6 last night and played through 2 of the las few missions with out a CTD.

The Point of the Thread is to tell others people that are Crashing to look at that Crash Log at the very bottom and see if the CPU clock speed is there. I never noticed it until yesterday.

I explained why in your other thread on the same topic.

Some reporting tools round your clockspeed incorrectly. If your CPU at any point hits 4.701gHz, some reporting tools report 4.8gHz.

Hence why I said to use something OTHER than PrecisionX that allows you to track your actual CPU speed to see if Doom is mis-reporting - which it probably is, becuase it should not be able to overclock your CPU in any way.

Edit: and if toning down your clock speed fixed your crashes, your overclock was in some way unstable. Did you test it under Prime95 and AIDA?

DOOM is not going to overclock your copy for you past what is set in your bios. As stated there are lots of tools you can use to check. Most likely it's just a rounding error on DOOMs part.

As I said a couple of Times I Brute force Tested my Clock of 4.7 Ghz actually for a few days before I decided I would keep it. The only Game or software that has crashed my computer is Batman Arkham Knight.

I have run Firestrike several times in a row which will cook your Processor. Crysis 3 is the most Demanding Game I think I have on the Processor but it does not crash at 4.7 ghz.

I am actually an Electrical Engineer. The Skylake Processors have a few issues that are of concern. Since I finally got my Computer completely Stable back when this Hardware actually were for sale on day 1. In other words I preordered my Motherboard and I was one of the few people that actually was able to buy the GSkill 3200 memory back then. I missed the first run of the i7 Skylake so I bought the i5 6600k.

I bought my i7 6700k in February 2016 so its 4 months old.

I have been gameing since before DOOM. I am over 50 :)

There may be a way to push the Skylake and actually other processors beyond the Clock in the Bios. If anyone could do it its the guy who wrote the DOOM engine. He developed Cryteks engines.

If I make it to the end of the game now at 4.6 ghz with out a CTD then I am fine with that. Its better for the Processor anyway.

The thing is other users who have overclocked their Processor to what they have determined to be the limit may in fact be in this same situation.

I cant say for certain unless I make it to the end. Thats 4 more missions.

Ill let you know.

Define "Brute force Tested". Unless you did a 24-hour run of Prime95, and AIDA64, you don't have something that I would consider stable.

And some applications will simply use something that crashes your overclock, no matter how stable it is - when I took my current CPU to 5.2gHz, it tested stable in everything I threw at it.

Except Google Chrome - for some reason, that exposed the limit in my stability.

And unless you are running Doom in administrator mode, it isn't overclocking your CPU.

correct me if im wrong but doesnt your overclock run at all times to the chosen setting all the time.i always believed it stayed where it was set.it does not throttle up.sorry for going off topic but this is the first i heard of this.

I always thought the same thing but apparently with newer motherboards and maybe Skylake Processors allow this to happen.

Power is one of the selling Points about Skylake. It is supposed to run Cooler and be able to achieve higher clocks due to the fact that it can run cooler just by design. And it does.

When the number crunching is not amounting to much the Processor isnt running at its highest speed because it doesnt need to. But as the number of calculations and speed at which they occur then the Processor will "Throttle" up to its top speed.

From an Engineering Perspective. DOOM is written to run on MANY different Processors each having their own Assembler Code that it understands.

When I used to code in C and C++ I would have some Subroutines written in Assembly Launguage but it was specific to a specific Motorolla Processor.

I wish I could confidently say I know everything. But I dont although I know enough to say that at the lower levels of DOOMs Engine Code it has to determine what Processor it is running on and it has to be able to talk the Assembler code specific to every Processor. If not the Processor will not know what to do and it will fail.

For example in the Crash Log there are several Registers listed. Like the "Stack Segment", "Code Segment". Those are terms that are used when talking about Assembly Code and Low level programming for Processors and Controllers.

So they are looking for Low Level corruption. I would say say that DOOM pushes a Processor to its absolute limit and thats why we are seeing some significant differences between AMD and Intel.

The Game is Completely Amazing and in fact It is my favorite PC Game ever.

If I didnt like the game I would of long ago packed it up and gone. In fact I have never discussed technically a game like this ever.

At this point I wish I could find out from people that get the CTDs to the Crash Log if their Processor Clock Speed is first even reported and second is it the speed they have their Processor set at.

I really would like to know.


As far as rounding the Clock Speed up from 4.71 to 4.8 nah that doesnt make any since and considering the level of technical specifics about the DOOM engine I would hope that their Crash Log would at least accuratly determine the Processor Speed. They obviously want to isolate out those People that may be CTDing due to extremely high Clock Speeds.

4.7 Ghz is really the safest limit for an i7 6700k in everyday gaming. I dont Water Cool but I have Excellent Air Cooling. I actually bought 2 new outtake fans last week just for this subject matter. And they do pull more hot air out of the PC.

If you read all this I hope it is helpful. I will keep at this game till the end. I have 105 hours into it now.

Oh and this thread is not an argument thread. I posted it to be helpful to those people that are suffering the Randam CTDs to the Crash Log. As far as my knowledge about Building Computers I really dont think its a relevant question for a 50+ year old man who has been building machines since you could.

[Samael]

Ok i will say this. This is for everyone with CTD problems.

If you have CTD. YOU SHOULD HAVE tried everything possible to fix them. Sometimes it's the game and sometimes its not.

Removing your overclocking should be in the list of stuff you try to fix them. So if no one thought about this ... i'm suprised.

And unless you are running Doom in administrator mode, it isn't overclocking your CPU.

More to the point, there is no end user test that can fully validate a processors stability. There are so many different instructions and there is no test available to us that tests all those instructions. The engineers at Intel have access to far more sophisticated validation tests then we do.

Anytime you OC to failure and simply back down to where the handful of tests you run finally pass, you probably arent' as stable as you think. Somewhere there will be a program that executes an instruction that causes a crash that would probably not have occurred if the CPU was at stock speeds. Then you factor in memory overclocking and it muddies the water even more. I've been overclocking for many years, and I too have come across instances where everything appeared to be stable... Except for something relatively simple like Internet Explorer.

I still OC because it's fun to squeeze out some extra performance, but I call it quits at a frequency that is far lower then what I "could" get it up to. And even then, if something unexpected happens, I look at my OC first and eliminate that as a possibility before blaming the software. That said, I've had DOOM CTD even on stock clocks.

I'm impressed you would push a 6700k to 4.7 for everyday use air cooled. What are your temps while playing and @ load with cpu and gpu.

I have a Older Model Full Tower from Lian Li. If your familiar with their cases you will know how big it is. Everyone in this forum would refuse to use the computer because it sounds like an Airplane.

Since I play with Headphones on 90% of the time the fan noise doesnt matter.

As for why I chose to stay at 4.7 ghz as my everyday use. Its because this computer is ONLY for gaming although i am typing in a forum right now. But other than. Well I watch movies and listen to music on it as well.

Nevertheless, 4.7 was determined to be stable after leaving it running for many hours on a couble of stress tools in some benchmarking tools i have and I have several. Because I use Windows 10 it is best to use a tool that is designed to run in Windows 10. I bought them incidentely.

As far as why I concluded things the way I did well I still may be right.

When they uploaded the Crash Code , the 83 meg update, that was when I started getting the CTDs just like several other people on this forum. Several people concurred that they felt that the CTDs were a by product of the Crash Code update Dialog.

It still may be. The only way I would ever know for sure is if they removed it and they just are not going to do it.

The fact that it either thought my processor was running at 4.8 Ghz or if it actually was I wont know.

I do remember "Vaugly" that Crysis 2 created the same situation for me and I downclocked the Processor I was using.

Yes I agree under normal circumstances like if it was doing from the beginning and I had no other possiblitly that seemed so obvious. I mean the Crash Logging Dialog is bugged and doesnt function. It freezes and sometimes causes a System Lockup.

So with this in mind , I was FURIOUS they did not make that update optional.

It clouded my ability to look at every single possible legitamate reason.

Again I still think my Computer may have played the game through to the end if they did not put that broken Crash Code in the DOOM.exe.

So now at about 8pm I have played through 2 missions with all secrets and collectibles Playing well 7 hours or more today and I have not gotten a CTD after going to 4.6 Ghz.

For anyone that thinks ID's decision to leave that broken code in the game is just wrong. It serves no other purpose now but to generate an html file with crash data. They DO NOT need the dialog to start (its another process) and freeze on the desktop.

There is a slight difference in some games between 4.6 and 4.7ghz. Thats why I had it on 4.7. But I am ok with 4.6. It all comes down to the Code and the number crunching. The syncronization is what the problem is most likely but I still think their Crash Code is the cause.

Lastly. If you read there statement about what they are fixing in the upcoming patch they address CTD and that they are fixing them.

As for me the stress of this has almost broke me so I am leaving my machine at 4.6 ghz

Like I said the point of the Thread was to shout out to other people like me frustrated with that dam Crash Code locking up and freezing and there are several people that feel the game was running fine until that update.

As far as the psychology of the situation and the actual reason why I didnt consider my Processor's Clock speed as being the catalyst , well sorry I aint seein a Shrink about it.
