Non OC
cpu 4670 default
mem 2666 default with 1.65 v
Using onboard gfx

This is a HTPC used only to play video files

Temps are fine at no more than 48oC
Been running fine for years until a few weeks ago since then the above img has happened on at least 4 occasions and pc has frozen requiring a reboot

Any ideas?mem maybe?but I have done a memtest for about 1 hour no errors at all

Could be the onboard graphics failing, have you got a gpu to put it to try?

I did try that a little while ago but for some reason could not get a display(set it to use gfx card and auto)neither worked.gfx card worked fine in another pc
Will try Furmark tomorrow night
Plenty of airflow in the case too
 
Well just completed 3 runs of 3d mark back to back
Not a crash in sight:confused:
Also ran a stress test with 100% usage on all cores for 10 mins same all fine,temps at 55oC
Any other suggestions?:)
 
Default windows 7 drivers,has been since it was first loaded or updated itself
If cable surely it would just fail?It is intermittent,works for ages then suddenly goes like the pics and crashes(cable is not moved).No warning,no stressing of system just playing video files
Its a weird one to be sure
Gonna give it another go tonite ,if it crashes again its gonna have to be a new/other system(spares box)
 
I would check for a bios update and chipset ect, If you can run mem test for longer that would be ideal to try and get more passes in with no errors.

That's some serious ram speed, the IMC on the CPU likely won't like that without some voltage tweaks.

Edit - strange it's run fine all this time though. Still, I'd lock it at 1600mhz for now
 
Knocked the ram down to [email protected] see how i get on for now :)
Thanx for the suggestions
EDIT:Re Bios there are later Bioses available but next up means you cannot downgrade so I have avoided updating. (GA-Z97X-SLI)

Update:
Been running ok since the first now
Fingers crossed the drop in speed and volts on the ram sorted it :)
Thanks guys

Strange that dropping the speed has not affected the WEI rating at all:confused:
 
The memory should run at the expected speed no matter what, if your memory is 2666mhz, why would you run it at 1600? As for updating bios, I personally do that every time a new bios is available myself.
 
Memory HAS BEEN running at 2666 for MANY years
Just recently it was crashing frequently,so I dropped the speed and volts to fault find as it were
You did read the opening post I made right?

Anyway at the moment it has been used for about 5 days/evenings now with no crashes and no loss of discernible performance so I will keep it at 1600

Re Bios
If i upgrade i cannot go back according to the info on the manufacturers page,why would they do this?
Always been able to down grade in the past

The RAM is no doubt capable of running at 2666, but the IMC on the CPU probably cant without specific voltage tweaks

Yeah I read it mate, just find it odd that you should have to lower the speed just for it to be stable, something is defo not right there.
 
True.something is definitely up but for now so long as it plays i am happy.it is only used for a htpc and i just wanted to switch it on and chill with a beer and a video .☺
 
That screen looks very much like gpu ram is the problem.
I've had similar from pushing gpu ram to far.

If performance is OK with the slower ram then leave it.

You can probably get the ram stable at a higher speed by tweaking some voltages or timings.
