possible hardware issue

[mazelda]

Thanks guys

I have been playing around with my fans and then tried another stability test as per the first attempt that lasted 6mins twice

This time it ran for 2hrs 59mins so am going to look at more cooling options first.

I'm going to try another test but not include the graphic card this time

Interestingly while I had the cpu at stock,I ran p3d and to be honest I noticed absolutely no difference in fps,admittedly not in a heavily built up area but still in the high 60+ fps range.

I would have thought that with the increased cycles ie 3.9 stock to my 4.5 oc I would have more fps

any idea why I'm not?

 

 

Remember overclocking is linear. If you work out the overclock in terms of the extra percentage, and add that to your average frame rate, you can see it's actually not a huge increase.

In regard to the CPU, if it's a reasonable distance form TJMax, and not throttling back, it won't effect your overclock.

 

In regard to the motherboard, it is possible for the voltage regulators to be too warm and affect the overclock.

 

I don't believe you've told us your temps yet.

 

CPU temp under load?

Motherboard temp under load?

GPU temp under load?

 

Which make of enclosure do you have, and how are the fans configured?

 

 

My guess would be your overclock settings though.

Hi all

Ok so I have run AIDA64 overnight running just cpu,fpu,cache,and sys memory

It has run for 13hrs

at that time the max temp for the cpu was 76c average temp is low to mid 60 for all cores with hyperthreading on

motherboard was 33c

and the gpu while under the previous test that lasted nearly 3hrs before stopping was 68c

The fact that testing the first 4 but not the gpu would suggest that the oc itself is fine having run for 13hrs

I am thinking that it may well be a temp thing now or that it might be a gpu issue.

 

I have a corsair obsidian 750d case at the moment the fans are configured as

 Front is suck air in

Top is draw air out ( This is my water cooled corsair h110 cpu cooler)

Back is draw air out

Bottom is suck air in

I am thinking of changing the top to suck the air in and the front to draw air out, because the outside ambient air is lower than that inside the casing which should make the cpu cooler still, because heat rises the front fan is lower down then it may not draw as much heat away.

 

anyway will have to see 

 

Interested in your thoughts though

I would recommend you checking all the temp-sensors in the CPU - with this software: 

http://www.techpowerup.com/realtemp/

It will tell you each core's spesific temp, and the temprature "package". A good hint to if you should de-lid the CPU or not, is a +20 difference between the cores (they should stay around the same - if the TIM and heat-spreader is doing their job correctly, and the heat spreader is relatively flat, and not curved in any way..).

 

What about the memory - is it clocked as well?

Hi Kristolz

 

I should have said that although I had AIDA64 running I also had realtemp running as well and the temps were all around the same it was just the max temp I quoted

everything was pretty linear with realtemp and matched what I was seeing in AIDA64

 

the mem I believe was not overclocked

No, not necessarily! Just because it's run for 13 hours does not necessary mean the overclock is okay. Despite thorough testing, I have had an overclock fail about once per week. Turned out to be RAM timings that needed to be slackened.

 

All your CPU temps are within the norm. And I seriously doubt you would have cooling issue with a great case like the 750D.

 

I presume your temps are core temp? Not CPU temp which is typically lower than core temperatures.

 

As I've said before, your system should be tested for at least a week, with no overclock at all, just set to optimised defaults. If it still causes issues suspect something other than the overclock. If there are no issues, then suspect the overclock.

Hi

Yes they are core temps.

I ran another test with all 5 test running and this time its not failed after 14hrs.

I've done nothing different chked about memory and that was not oc'd so I'm stumped

The only thing now is to try a few long ish flights and see if p3d holds up,as this is what started the whole thing

will let you know
