Hey guys,
Bought an EVGA GTX 670 superclocked with 4GB vRAM a couple of months ago and was really happy with it until I noticed some lag while playing Borderlands 2 whenever I was in Sanctuary so I decided to do a little bit of overclocking (My first time overclocking a Kepler). I ran a stock Heaven Benchmark before overclocking so I'd have something to compare my results to and it came up with a score of 908. Not bad, I thought. So I eagerly started overclocking following the quick version explained in SeanPoe's "GTX 670 Overclocking Master Guide" on the overclock.net forums and went to town.
Using EVGA Precision-X I set a custom fan curve to make sure the temps never exceed 70C as suggested in the guide and continued with the usual overclocking routine. I managed to get a stable overclock at
GPU clock offset: +74
Mem clock offset: +158
I pushed the voltage to the max (1.175V) and hit apply, but ever time I open the "adjust voltage" panel it seems to be reset to the default value of 988mV so I'm not sure what's up with that.
I wish I could upload pictures here, but anyway here's the results of the Heaven Benchmark with overclocking:
-----------------------------------------------------------------------------------------------------------
FPS: 41.5
Scores: 1044
Min FPS: 11.6
Max FPS: 103.1
Hardware
Binary: Windows 32bit Visual C++ 1600 Release Mar 7 2012
Operating system: Windows 7 (build 7601, Service Pack 1) 64bit
CPU model: AMD Phenom(tm) II X4 955 Processor
CPU flags: 3214MHz MMX+ 3DNow!+ SSE SSE2 SSE3 SSE4A HTT
GPU model: NVIDIA GeForce GTX 670 9.18.13.623 4095Mb
Settings
Render: direct3d11
Mode: 1920x1080 8xAA fullscreen
Shaders: high
Textures: high
Filter: trilinear
Anisotropy: 16x
Occlusion: enabled
Refraction: enabled
Volumetric: enabled
Tessellation: extreme
-----------------------------------------------------------------------------------------------------------
What I'm most concerned with here are the scores. When I did a little bit of research I found most people overclocking their GTX 670's were getting scores in the range of 1150-1250 and I'm a solid 100 points below the low end of those that have posted their scores online Is something in my system bottle-necking the benchmark process, or did I just get a lemon of a GPU?
From GPU-Z:
GPU Clock: 1041 MHz
GPU Memory: 1581 MHz
GPU Boost: 1120 MHz
--
Default Clock: 967 MHz
Default Memory: 1502 MHz
Default Boost: 1046MHz
For those of you who'd like to see, here is a specs list for my PC:
EVGA 04G-P4-2673-KR GeForce GTX 670 Superclocked+ w/Backplate 4GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card
Gigabyte AM3 AMD GA-880GMA-UD2H (probably rev 2.0) Mobo
AMD Phenom II X4 955 Black Edition Deneb 3.2GHz Socket AM3 125W Quad-Core Processor
X-Power 650 watt PSU
2x (G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL)
^ total of 8 gigs of ram (4x2gb)
Crucial M4 128GB SSD
Seagate Barracude 1TB HDD
Windows 7 Home Premium 64-bit OEM
Let me know if I'm forgetting anything important.
Any help/info would be appreciated
