Hi all, I have a bit of a question/quirk I could use some eyes on. So, here it is. Running the card (780 Classified) stock LN2 bois and enabled k-boost. Ran tests for heat load values and power draw. I am running Prime 95 and/or FurMark. The system is working fine everyday use, oc is stable, hardware is fine, afaik, etc...
To summarize, the card will load up fine with just FurMark running (108% TDP) but when the cpu is being 100% loaded up, the card will throttle down to 65% TDP to 80% TDP, with average of about 71% TDP or just drop out completely. The clock remains steady however while the TDP is low.
The first two pics are sidle and then just p95. The first combined test was with p95 running first, and then engaging FM. After that, I ran just FM. I then ran both with FM running first, and then engaging p95. The card just simply dropped out after engaging p95.
Also to note, enabling k-boost disables the gpu loading info, just showing 0% all the time. I did a little research and it’s known with no fix yet. So I have to go off of % TDP and a few other values. Pics show one specific run into another.
Idle = 125W
F@H = 525W
Heavan = 475W
Valley = 400W
FurMark = 500W
Prime95 = 375W
FurMark + P95 = 650W
Any ideas why the card is throttling when under full p95 stress and max load? The psu is 760W and the load numbers are at the wall with a Kill-A-Watt. Please ask questions, I tried to capture the issue as best I could without writing a book or rambling. ThanksEdited by chartiet - 3/23/14 at 11:28am
