Overclocking InnoVision's PCI-E video cards
Since we have been long at overclocking video cards based on 6200TC/6600/6600GT, it will not be difficult to give an impartial estimate of the overclocking capability of our today's heroes because "who has never tasted bitter, knows not what is sweet".
Let's start with the «little kids» - two GeForce 6200TC boards. For the chip, they demonstrated a surprising solidarity - both attained the 425 MHz bar. As regards the video memory overclocking, we were unable to overclock the 16Mb modification at all – any attempt to raise the frequencies resulted in image artifacts. On Inno3D GeForce 6200TC 64Mb (256Mb), we were able to overclock the memory to 670MHz DDR.
Note that this GPU overclocking result cannot be regarded fantastic since almost all formerly tested 6200ŇŃ boards offered somehow better overclocking of the GPU – 440-450MHz on the average. In this category, the very first GeForce 6200TC card, a reference sample by NVIDIA proves an absolute champion. We were able to overclock it to 493(!) MHz for the core.
As regards the results for memory overclocking, all depends on how fast (to be more precise, how slow) the memory on the card is installed. In particular, we were able to overclock boards of 3.6ns video memory most often to 650-670MHz DDR. But overclocking the GeForce 6200TC equipped with 5ns memory (we did have these as well) amounted to merely 460MHz DDR (the nominal speed is 400MHz DDR).
That is, we can safely state that memory overclocking for both these Inno3D video cards proved successful. At the same time, it should be noted that the 256Mb version is equipped with 4 ns memory (nominal frequency 500MHz DDR). Therefore, we were able to overclock the memory by 170MHz above the nominal!
Then there goes the NV43-based GeForce 6200 in our list. We couldn't help attempting to unlock the pixel pipelines. Since the chip we got was of revision A2, there were no much issue at that. You can judge the performance boost yourself by the above graphs. Note that we did the overclocking on a locked (!) card. The total is 450/650MHz. Is that much or little? Let's see.
For the chip, it seems normal enough. Of course, we used monsters capable of running at 500 MHz or higher without modifications to the cooling system, but generally 450 MHz is the limit for standard cooling. By the way, the "full-fledged" GeForce 6600 even failed to reach that threshold - we were able to overclock the chip to merely 425 MHz. The poorest chip overclocking result for 6600/6200 (NV43) from our vast collection is 370 MHz. But that is already an "accident".
The overclocking for video memory in Inno3D GeForce 6200 amounted to 650MHz DDR, which is good enough for 4 ns memory. We were able to overclock Inno3D GeForce 6600 equipped with the same memory to 625MHz DDR.
Now we are moving to the last PCI-E board by InnoVision – GeForce 6600GT. In terms of overclocking, it brought no surprises – 560/1070MHz. The GPU overclocking is practically identical to all the cards we tested. As usual, video memory overclocking depends on the quality of memory installed on board, because there are solutions with both memory regular for GeForce 6600GT offering 2 ns access time, and the faster modifications offering 1.6 ns access time.
Lastly, a couple of tests for overclocked cards as compared to the nominal operation modes.
