The die marking is the same as on Palit GeForce GTS 250 1G – G92-428-B1, but this particular sample was made on week 51 of 2008. The clock frequencies are also a little different from the reference and equal 745/1848MHz instead of the reference 738/1826MHz for the primary and computational die domains respectively. The graphics processor works in maximum configuration available for G92: 128 universal shader processors, 64 TMU and 32 RBE.

Just like Palit GeForce GTS 250 1GB, Gainward GTS250 2048MB boasts very unusual configuration of the interface connectors that includes DVI-I, HDMI and D-Sub ports all together at the same time. The card doesn’t support outdated analogue video Outs in Composite, S-Video or YPbPr formats any more. Besides that, the card has an S/PDIF In connector typical of Nvidia solutions, and two MIO interfaces for building SLI or three-way SLI configurations.

The cooling system is exactly the same as the one on Palit GeForce GTS 250 1GB, so we won’t dwell on it here. The main part of this system is a pretty low heatsink made of thin aluminum plates and connected to the copper heat-spreader plate with two heatpipes.

This cooling system may seem not very efficient at first glance, because the air flow needs to be turned around abruptly on a very short distance of only one and a half centimeters. However, as we have already revealed in our Palit GeForce GTS 250 1GB review, this solution does it pretty well and proved quite efficient. Its only noticeable drawback is that the hot air is not removed outside the system case.

Gainward card uses Everflow R128015BH fan measuring 80x15mm and featuring 3.84W maximum capacity. At maximum rotation speed it gets pretty loud and its rotation speed control system starts working only when the OS and drivers have been loaded in full. As soon as it kicks in, the card becomes almost completely noiseless.

The heat-spreader base is covered with a layer of light-gray thermal interface. It is of pretty dry consistency and holds the GPU and the cooler base so firmly together that we were very concerned about the well-being of the fragile chip when we tried to remove the cooler. The memory chips are cooled with two metal plates equipped with elastic thermal pads. The cooling system sits pretty securely on the card. Besides, the protective casing prevents the heatsink from shifting, no matter what you do.

Overall, the design of Gainward GTS250 2048MB didn’t reveal anything new to us and proved to be exactly the same as Palit GeForce GTS 250 1GB we have already discussed earlier. The only difference is the use on 1Gbit memory chips. This Gainward solution has two drawbacks that you can notice with a naked eye: the need for two power connectors and the cooling system that doesn’t remove hot air outside the system case. However, the latter issue can actually be stricken out because of low power consumption of the G92b chip.
