![]() ![]() Typically you can tweak on core clock frequencies and voltages. As most of you know, with most video cards you can apply a simple series of tricks to boost the overall performance a little. If this is an indication of my 2x SLI accomplishment, my core would peak to 1,478 and memory to 3,758 (or roughly 7,500 - depending). People were trying to reach 1,500 Mhz core and 8,000 memory (or 4,000 depending on how you look at it). Still, I can't even remember what the overall core and memory stress speeds were. I found my MSI GTX 970 core overclock around +150. Raise the power limit to 110% - which is likely a maximum. The slider is divided into increments of millivolts. It isn't a matter of setting the voltage up "2%," but upping it to what I remember as a a recommended limit of 20 mV. I got the parameters and variables confused with GTX 1070 OC'ing. I'd removed one of the GTX 970s from the system but left my Afterburner installed with settings, so I can give you an idea. After that, you can up the memory clock, and some people were claiming stability at either 4,500 Mhz or 9,000 Mhz depending on whether or not you're talking about double-data rate. I cannot remember my final core stress speed, but that information is "out there" and you can find it. You can only minimize their occurrence by doing thorough homework. All this time, you're testing it with a Benchmark like Unigine Valley, and hopefully, only the video driver crashes and recovers, so that you don't blue-screen the system - but such things are hard to avoid. With the second step, you move the slider for the GPU core from its original (STOCK!) setting in 25 or 50 Mhz intervals. I had two of them in SLI with a stable overclock. You are obviously advised to use MSI's AfterBurner, but they all work. Here's one, for instance, in a HardOCP review: You need to do some web searches to get a short-cut to a stable overclock. ![]()
