i just bought a Zotac GTX 960 AMP! 4GB edition. tested the GPU running MSI Kombustor while monitoring with GPU-Z without overclocking. i got a couple of concerns that needs clarification and need advice if i should return this for replacement.
1. When running all different types of test in Kombustor, GPU load reaches 99% and GPU Core Clock reaches to 1442.8 MHz. According to Zotac webpage, Zotac GTX 960 AMP! 4GB has Core Clock: 1266 MHz and Boost Clock: 1329 MHz. Why is it running more Clock Speed? Is this the doing of the Nvidia's GPU Boost? making the GPU Core Clock run more that is beyond on what is advertised?
2. Since the GPU is running more Core Clock. GPU Temperature reaches to 83 Degrees Celsius!
i know its not much and should be normal. but i'm just a little concerned because my previous GPU (R9 270x and GTX 950) never reaches 80 Degrees in full load. My case is a DIYPC Cuboid-R. rear has 1x 120mm fan exhaust, front has a 200mm intake fan and top has 2x 120mm exhaust fan.
3. What really bothers me the most is that this GPU makes a humming sound or sometimes buzzing when running stress test in MSI Kombustor. Coil whine maybe? Its not loud. i can barely hear it especially when the case side panels are on. i have to get close to my PC to hear it. Most reviews of this GPU did not report any coil whine or humming sounds. Maybe i just got unlucky and got a whiney GPU. im thinking thats its the PSU, its not enough to give power to the GPU. i have a FSP Raider 550w PSU (which also has random coil noises for some time now). Should i return my GPU for replacement or should i upgrade my PSU?
4. GPU-Z now also shows a new category on the Sensors tab: PerfCap Reason. i have never seen this from my old GPU. i have researched about what PerfCap is, i was relieved to know that this is just a tool to know what stopping my GPU to run more. what i want to know is why this showing up now? i have not updated the GPU-Z since November 2015.
PC Specs:
Intel I5 4570 proc
Gigabyte b85m-hd3 mobo
G.Skill Ripjaw 2x 4GB memory
Kingston V300 SSDnow
FSP Raider 550w PSU
WD Caviar Blue HDD
Thank you for those who can help me. if need more info. please let me know.
