ED Team f-18hornet Posted September 24, 2014 ED Team Posted September 24, 2014 GPU core is not overheating or it shouldn't when it has just 70-75°C in full load. It is your VRAM in your card. You have to slow it a little bit down. You can try 6700MHz if it's stable. AMD Ryzen 9 3900X, GeForce RTX 2080Ti, 32 GB DRAM, HOTAS TM Warthog, FSSB R3 Lighting, MFG Crosswind, Win 10 Pro
tango4 Posted September 24, 2014 Posted September 24, 2014 Well, I did downclock it to the maximum allowable by msi afterburner (-105MHz Core Clock and Memory at 6000MHz, after two hours of testing this afternoon, not a single crash!) A bit too soon to rejoyce, but thank you very much for your help guys. I had totally missed that point after lots of test. ED Tech support thinks my PSU is not powerful enough (750W with a core i72600K at 4.6GHz). I am doubt ful but that is possible. Anyway, it seems related to the graphics card somehow. I'll perform more thorough tests when I have the time. Once again THANK YOU VERY MUCH for taking the time to help me. Charles

Here is an example. Power Consumption GeForce GTX 780 Ti System in IDLE = 120W System Wattage with GPU in FULL Stress = 372W Difference (GPU load) = 252W Add average IDLE wattage ~10W Subjective obtained GPU power consumption = ~ 262 Watts Even in SLi it is fine. Power Consumption GeForce GTX 780 Ti 2-way SLI System in IDLE = 129W System Wattage with GPU in FULL Stress = 617W Difference (GPU load) = 488W Add average IDLE wattage ~20W Subjective obtained GPU power consumption = ~ 508 Watts So their incorrect unless the Power Supply is going bad. In a process of elimination ideology it would be one of the things I too would look into. But we have a mitigating fact, that being the history of users with that card. The resolution for them was to remove the overclock, I guess they just don't have time to look into their Forum. This was a Boutique Builder iBuypower rig.

tango4 Posted September 24, 2014 Posted September 24, 2014 Well, thanks, I'm not going nuts, then ! That's reassuring, i was starting to think that my PSU was not enough for my config although I double checked before buying a new graphics card. It is a pretty good PSU, a Corsair one, supposed to be reliable. And i did some stress test both for my cpu, and gpu without a single issue. Plus FSX,P3d and Xplane are running without any problem ! So to be honest that would be suprising. I'll keep doing some tests, but the first results are encouraging. There seem to be some issue beween their engine and these cards. Perhaps a problem in the way DX9 is handled ? Thanks again for your valuable inputs !
timc Posted October 10, 2014 Posted October 10, 2014 (edited) I am another DCS user suffering from terminal freezes. I also have a 780Ti and after 20 minutes of flying the system freezes. Sometimes it is for 30 secs or so before the sim goes into stutter mode and often I need to restart to recover the PC. Watching task manager there is a massive spike in CPU usage during the freezing caused by the System process. I have used Process Explorer to watch what is going on and it seems that a kernel thread is going ballistic; the offending cuplrit is RtlSidHashLookup. I haven't been able to get to the bottom of what is causing this thread to be so active - does anyone have any suggestions? In terms of PC specifics, I am using the latest version of DCS on a 4960K running at 4.5Ghz via Asus' AI suite, 8MB Ram with the OS (Windows 8.1) and DCS on separate SSDs.

tango4 Posted October 10, 2014 Posted October 10, 2014 Hi Tim, Well, actually, the suggestion made by Atalia saved the day for me. I haven't been able to make extensive testing, but it seems to be working. I am using a Gigabyte 780Ti Factory overclocked (CPU i7 2600K @ 4.6Ghz, 8Gb RAM, SSD for OS Win 7 Home premium 64bits, Standard Hard Drive for DCS). What i did was install MSI Afterburner, then downclock GPU Core Clock AND Memory frequency to the minimum allowed by this program. I made a few test flights and for the moment, no more crash. Even downclocked as much as possible, performance was still ok and sim perfectly flyable. I did not change anything else, so this seems to be related to this graphics card somehow (i tested LOTS of things before that, but never with success). And it's the onyly game in which I have this problem, including other hardcore sims (FSX, XPlane 10...) Hope that will help you. Charles

Charles Charles/Tango4, You (and the others who have suggested a graphics card issue) may be onto something there. I've installed Gigabyte's OC Guru (it's a Gigabyte card) and cranked up the fan speed for now. I also deleted the Saved Games folder just for luck. So far I've managed a 35 min flight without issues using the same test conditions as the freezing scenario and no problems. Before I would get 20 mins max. My graphics settings are all down low so I'll move them up and test again. The downside is that I feel like I'm sitting next to an Airbus with the engines running! I'll see if I can get a stable DCS set up like this then perhaps reduce the GPU clock speed in conjunction with reducing the fan speed. Fingers crossed and thanks for your help. Tim
