alainneedle1 Posted September 3, 2010 Share Posted September 3, 2010 To all of you using an overclocked GTX 480....would you mind stress testing your card with GPU OCCT and report back..... I'm asking because I get random freeze with OCCT GPU stress test but I'm fine if I use MSI Kumbuster so I need to know if OCCT is pushing the card to far compare to Kumbuster or if OCCT is screwed up......

UlfB Posted September 3, 2010 Share Posted September 3, 2010 Hi, I have used GPU OCCT to test my factory OC:ed card. No problems. The GPU OCCT puts a very heavy load on the GPU and temps go a lot higher compared to flying in FSX. What temp do you have before your system freezes?

The GPU OCCT puts a very heavy load on the GPU and temps go a lot higher compared to flying in FSX. What temp do you have before your system freezes? Thank you, UlfB.... That's what I was thinking about OCCT because the temp I'm getting with MSI Kumbuster are a lot lower compare to OCCT.... Temp are in check.......78C at 99% load for one hour of stress testing with OCCT at 800MHz on core clock / 2000MHz on memory clock and core voltage (mV) at 1050 The default clock on this card is 756MHz on core clock and 1900Mhz on memory clock.... The card is freezing if I try to go over 800MHz....I may need a little more core voltage (mV).... I would like to know from other guys here who have overclocked their cards from default what kind of result you are getting with OCCT compare to MSI Kumbuster .......

Ausiguy Posted September 4, 2010 Share Posted September 4, 2010 That's unbelievable... MSI called their card the Kumbuster Link to comment Share on other sites More sharing options...
alainneedle1 Posted September 4, 2010 Author Share Posted September 4, 2010 That's unbelievable... MSI called their card the Kumbuster LOL ...no Kombuster is a GPU stress test from MSI....here is the link... http://downloads.guru3d.com/MSI-Kombustor-(Furmark)-0.7.0-Beta_d2461.html Was I taken for a ride here??

alainneedle1 Posted September 4, 2010 Author Share Posted September 4, 2010 UPDATE: OK after more testing with GPU:OCCT for severals hours at full screen, shader complexity Optimal 8, Error Check and resolution at 1920 X 1080 here is the best I can do with my card .....temp stayed at 78C at full load (99%)....temp idle at 35C. Core Voltage (mV) .....1075 Core Clock (MHz)........820 Core Shader (Mhz).....1640 Memory Clock (MHz)...1947 Fan Speed (%)...........70 So OCCT is working fine, anything higher than that on any sliders beside the fan speed slider and the card will freeze after 3 minutes no matter what combination I'm trying. With MSI Kombuster I can push the card up to 880MHz on the core clock 2100MHz on the memory clock with 1100mV on the core voltage for one hour + but the card will freeze playing games after 15 minutes up to one hours depending on the game. So my conclusion is this, OCCT will give you a lower overclock compare to MSI but your card will be 100% stable after reaching one hour of stress testing with OCCT. It would be nice if somebody else try both stress test software on their manually overclocked card and post their result here so we can all compare our finding....

Those numbers look about right Alan and jive with what the my 460 can do. Thanks for taking the time to do the BM. jja Link to comment Share on other sites More sharing options...
UlfB Posted September 4, 2010 Share Posted September 4, 2010 I tested FSX with an OC to 825MHz and compared to the default factory OC at 756MHz. I couldn't notice any difference. Average fps maybe +1 with OC. Link to comment Share on other sites More sharing options...
jjjallen Posted September 4, 2010 Share Posted September 4, 2010 Depends on if you are CPU bound or not like near a major airport. The main advantage of GPU OClking would be enroute with clouds ect.. jja Link to comment Share on other sites More sharing options...
UlfB Posted September 5, 2010 Share Posted September 5, 2010 Depends on if you are CPU bound or not like near a major airport. The main advantage of GPU OClking would be enroute with clouds ect.. jja Might be true. I haven't tested that yet, but will do. But I suspect that the bottleneck on my system isn't the GTX480 and it's ability to process a lot of cloud textures. I suspect that the bottleneck is FSXs (CPUs) ability to process and transfer the cloud textures to the graphics card. But that's just my guess. I'll do some testing with several dense cumulus cloud layers Link to comment Share on other sites More sharing options...
UlfB Posted September 5, 2010 Share Posted September 5, 2010 I did a test with three dense cumulus cloud layers and with my GTX480 at 756MHz and at 825MHz. No difference in average fps. No noticable difference in IQ and smoothness. Maybe the results would be different on another system with faster mobo, CPU and memory. Link to comment Share on other sites More sharing options...
UlfB Posted September 5, 2010 Share Posted September 5, 2010 Here are my OC settings: And my fan profile: Max GPU temps in... FSX is 58C 3DMark06 is 64C But no noticable difference in FSX. Link to comment Share on other sites More sharing options...

I'll do some testing with several dense cumulus cloud layers AI traffic can also cause a 40+ FPS hit at a busy airport. I found this out outside of LA when I toggled UTII traffic off (ctrl+shift+t). The moral of the story is that FPS is a lousy way to BM FSX unless you can control all the factors. jja Link to comment Share on other sites More sharing options...
UlfB Posted September 5, 2010 Share Posted September 5, 2010 I agree A smooth is FSX with crisp textures and excellent IQ is the goal Link to comment Share on other sites More sharing options...
