MSI N660Ti PE 2GD5/OC TwinFrozr IV 2GB
The MSI N660Ti PE 2GD5/OC TwinFrozr IV is the first Power Edition series product we’ve got a chance to test. We are curious to learn its differences from reference products as well as from its more advanced cousins.
The eye-catching box offers basic information about the product, mentioning its triple overvoltage protection and enhanced PWM design.
Detailed product specs, minimum system requirements and key features are listed on the back of the box in two dozen languages.
Included with the graphics card are two power adapters, one DVI->D-Sub adapter, a CD with drivers and utilities, an installation guide, and a promo booklet.
The graphics card is manufactured in China and costs $299. It is shipped with a 3-year warranty.
Like ASUS products, MSI graphics cards can be easily identified by their stylish design and exclusive TwinFrozr cooler.
The MSI N660Ti PE 2GD5/OC TwinFrozr IV is the second longest card in this review at 257 millimeters. You should note this fact if you’re planning to build your gaming configuration in a cramped system case. The height of the card is 37 millimeters.
The standard selection of video interfaces (DVI-I, DVI-D (dual-link), HDMI and DisplayPort) allows the GeForce GTX 660 Ti to support up to four monitors concurrently. The MSI card is no exception in this respect.
The SLI and power connectors are identical to the reference card’s, but the PCB is original:
We can see a 5+2+1 power system (GPU+memory+PLL) here.
These are heavy-duty Military Class III components: tantalum-core Hi-c capacitors, Super Ferrite Chokes and Dark Solid capacitors. MSI suggests that the high-quality components will help an overclocker get the very best from the GK104 chip.
The GPU is dated the same week as the GPUs of the ASUS and Gigabyte cards.
The card is specified to have a GPU clock rate of 1020 MHz boosted to 1098 MHz, but our monitoring tools showed that it peaked to 1176 MHz. So, we’ve got some good factory overclocking here. The amount (2 GB) and frequency (6008 MHz) of the onboard memory are perfectly standard and we see the same Hynix chips once again.
Let’s glance over the MSI N660Ti PE 2GD5/OC specs and proceed to its TwinFrozr IV cooler.
The original cooler from MSI may be familiar to you from our earlier reviews because the company installs it on many other of its products. It consists of an aluminum heatsink with four 8mm nickel-plated copper heat pipes that go out of a copper base.
It has two fans covered with a metallic casing from above. The memory chips and power system components are cooled by a metallic plate with thermal pads. The parts of the heatsink are soldered to each other.
The 80mm fans are manufactured by Power Logic (it is the PLD08010B12HH model) and run on dual ball bearings.
That’s not the best choice in terms of noisiness but perfect in terms of service life. However, MSI claims a 17.1 dB lower noise level and a 14°C advantage in temperature in comparison with the reference cooler. The TwinFrozr IV copes with its job well enough:
Automatic fan mode
Maximum fan speed
We have 70°C when the fans are regulated automatically (1620 RPM) and only 55°C at the maximum speed (4170 RPM). The noise factor will be discussed later on.
In our overclockability test the MSI card was stable after our increasing its GPU and memory frequencies by 90 and 1160 MHz, respectively.
Thus, the MSI N660Ti PE 2GD5/OC is second among the eight cards in this review in terms of overclocking potential. Its peak stable frequencies were 1110/1188/7168 MHz.
The temperature of the overclocked card increased by 3°C to 73°C, the two fans rotating at 1740 RPM.
The peak GPU clock rate reached 1266 MHz during our tests. We wouldn’t view the MSI version as something special, but it’s a well-made product that’s worth considering.
