![]() #1080p civilization v backgrounds windows 7All tests were performed in Microsoft Windows 7 Ultimate 圆4 SP1 with all critical updates as of that date and the following drivers: The test session started on May 14, 2012. 16 GB of system DDR3 memory worked at 2 GHz frequency with 9-10-10-28 timings and 1.65V voltage. The processor Vcore was increased to 1.46 V in the mainboard BIOS. In order to lower the dependence of the graphics cards performance on the overall platform speed, I overclocked our 32 nm six-core CPU with the multiplier set at 37x, BCLK frequency set at 125 MHz and “Load-Line Calibration” enabled to 4.625 GHz. Power supply: Xigmatek “No Rules Power” NRP-HC1501 1500 W (with a default 140 mm fan).Control and monitoring panel: Zalman ZM-MFC3.System case: Antec Twelve Hundred (front panel: three Noiseblocker NB-Multiframe S-Series MF12-S2 fans at 1020 RPM back panel: two Noiseblocker NB-BlackSilentPRO PL-1 fans at 1020 RPM top panel: standard 200 mm fan at 400 RPM).Backup drive: Samsung Ecogreen F4 HD204UI (SATA-II, 2 TB, 5400 RPM, 32 MB, NCQ).Drive for programs and games: Western Digital VelociRaptor (300GB, SATA-II, 10000 RPM, 16MB cache, NCQ) inside Scythe Quiet Drive 3.5” HDD silencer and cooler.System drive: Crucial m4 256 GB SSD (SATA-III,CT256M4SSD2, BIOS v0009).Sapphire Radeon HD 7950 OC Dual-X 3 GB, 384 bit, GDDR5, 800/5000 MHz.CPU cooler: Phanteks PH-TC14PE (2 x 135 mm fans at 900 RPM).CPU: Intel Core i7-3960X Extreme Edition, 3.3 GHz, 1.2 V, 6 x 256 KB L2, 15 MB 元 (Sandy Bridge-E, C1, 32 nm).Mainboard: Intel Siler DX79SI (Intel X79 Express, LGA 2011, BIOS 0460 from ).Nvidia GeForce GTX 670 and its competitors were tested in a system with the following configuration: Unfortunately, the GeForce GTX 670 is unsatisfactory in this test. The cheap plastic of the cooler casing and of the PCB extension with fan resonates, causing even more discomfort. Moreover, the cooling system of our sample changes its fan speed inconsistently as is indicated by the wavy shape of its noise graph. The reference GeForce GTX 670 is no quieter than the GeForce GTX 680. We’ve included the results of reference Nvidia GeForce GTX 680 and AMD Radeon HD 7950 cards into the next diagram for the comparison’s sake (the vertical dotted lines indicate the top speed of the fans in automatic regulation mode). The speed of the graphics card’s fan was being adjusted by means of a controller that changed the supply voltage in steps of 0.5 V. The bottom limit of our noise-level meter is 29.8 dBA whereas the subjectively comfortable (not low, but comfortable) level of noise when measured from that distance is about 36 dBA. The mainboard with the graphics card was placed at an edge of a desk on a foam-rubber tray. The noise-level meter was set on a tripod at a distance of 15 centimeters from the graphics card which was installed on an open testbed. We measured the level of noise using an electronic noise-level meter CENTER-321 in a closed and quiet room about 20 sq. This is 3☌ higher compared to the reference GeForce GTX 680 but the latter’s fan worked at 4200 RPM. At the maximum speed of 3750 RPM the GPU is no hotter than 65☌. The GeForce GTX 680 had the same GPU temperature but its fan speed was lower by 270 RPM. Let’s see what temperature the card has when its fan is regulated automatically and at the maximum speed of the fan.The GPU is as hot as 81☌ in the automatic regulation mode, the fan reaching 2190 RPM. We didn’t change the card’s default thermal interface. This test was carried out with a closed system case at an ambient temperature of 25☌. We used MSI Afterburner 2.2.0 and GPU-Z 0.6.2 as monitoring tools. Predator (2010) in five cycles at the highest settings (2560×1600, with 16x anisotropic filtering and 4x antialiasing). We checked out the card’s temperature while running Aliens vs. The unsophisticated cooler, short PCB and rather simple power circuit do not quite match the product’s price tag of $400, but that’s what Nvidia offers for that money. The GPU heatsink consists of a copper base with aluminum fins soldered to it.There is no vapor chamber and no heat pipes here.The reference GeForce GTX 670 cooler also includes a simple 70mm PWM-regulated fan and a tall heatsink for power system components. It hides an aluminum heatsink on the power components, a GPU heatsink and a fan secured on the plastic extension of the PCB. The plastic casing of the cooling system is fastened along its edge. ![]()
