I have a Problem white Memory Clock GTX560 Ti 448 Cores FTW

January 18, 2013 at 14:53:19
Specs: Windows 7, Core i7 2933MHz, 10GB ram
The Memory Clock of this card is set at 3900MHz from the stock tech specs, but it reads that is set only at 1950MHz in the screen of the EVGA Precision control panel and any other monitoring software that i use So my question is that if my GPU is broken up or it is normal that the memory clock runs under the a fore mention specs?, 'cos i been in trouble whit constant bad energy fluctuations and also some overheating issues when i play some games, specially whit the latest Total War game series. So help me please, and thanxs in advance

I thought everyone understood DDR (Double Data Rate) RAM by now. 3900MHz is the DDR rating, 1950MHz is the actual frequency the RAM runs at. 1950MHz X 2 = 3900MHz. In other words, there's nothing wrong. If you're having overheating problems, that's another issue unrelated to the graphics RAM. What's overheating, the CPU or GPU? Post the temps of both.

First of all, thank you for your reply Riider, that clarify pretty well my main question, but yeah, there is some specimens, like me, that doesn't know and for sure about some technicalities still, so when exists a doubt it is better to ask to people whit more knowledge about the subject : ). Secondly, and that is what leads me to ask about a probable damage to my card, is that every time i try to play the game Napoleon Total War, which is pretty demanding in terms of hardware and graphic requirements, it makes the GPU stop working causing a black screen and locks down my PC. By now i can't even run the MSI afterburner bench mark test whit out having the same issue, the only message that i receive from the Win7 system is that the Nvidia driver as stoped working. I notice the problem begins when the GPU monitoring Temp reaches the 78°C, and the CPU temp reaches at least 75°C wich i think that it is not to high. I currently use the EVGA Precision to manage the GPU fan speed, and Real Temp software to monitor the general PC system temps, but the only thing that seems to work for me was to underclock the GPU clock, the voltage, and the GPU memory clock, but the issue persists when i restore the full features, it is so frustrating. By the way everything else runs well, other games like Assassin's Creed 3, movies, etc, except that TW game.
