Hello everybody, I've been doing some thinking about ways to increase the performance of my 2x hd 6870's, and have gone down the path of using all the usual over clocking utilities, and getting reasonable results, hitting around 1000mhz on the gpu, and 1220mhz on the memory with a modest increase on the gpu voltage, and as these card offer no voltage control on the memory side of things, sticking with the default memory voltage settings.
Whilst playing around with the cards, and reading about other people's attempts at over clocking, modifying and otherwise boosting the performance of the cards, a thought occurred to me! I remember back, a year or 2 ago, I had 2 awesome hd 4890's, that offered an incredible amount of over clocking potential, in fact, if I recall correctly, they were able to clock the memory to around the same as the 6870, and the gpu somewhere in the vicinity of the 1150-1180mhz range, and also offered a far more comprehensive array of voltage control for both gpu and memory.
This led me to wonder why an older card could have so much over clocking potential, whilst a newer card offered comparatively so little, and I came to the conclusion that this was perhaps due to the 4890's use of the voltera control chips on the 4890, that seemed to mysteriously go missing on later amd graphics solutions.
So, with this information in mind, my questions are as follows:
Would it be a feasible idea to transplant the voltera chips from my 4890's across to my 6870's?
Would it be reasonable to assume that the graphics card, and the software would be able to recognise these chips and use them accordingly?
Is there something else that I have missed in regards to the voltage control of the 6870's that would give me greater control over the cards, and therefore better over clocking?
Finally, has anyone else attempted such an undertaking, I know plenty of people have volt modded their graphics cards and had varying degrees of success with things like that, but that's not what I'm aiming for, I want greater control over my card, so I would greatly appreciate suggestions of "why not volt mod it" not being thrown into the mix please?!
That pretty much it, looking forward to your ideas!!!
