Long time reader, thank you Dolk for your time in putting together this guide and answering questions. It helped me tremendously with my 9850, then the 940, and now my 1090T on my new Crosshair IV. Overclocking with this cpu and motherboard is very smooth, it was easy enough to stabilize a 4.1 at just over 1.4 CPU VID, with LLC on. Temperatures are fine on air (Zalman 9900 Max), but any farther in speed and the voltage has to be cranked up quite a bit and the temp creeps up farther than I would like. I was tinkering with Turbo Core, which I see you haven't quite posted up on; I see that most folk are disabling it, but I found that I can get up to what looks like a stable 4.35 or 4.4 on the three cores, which comes into play quite a bit during gaming and adds a perceptible boost in fps. My only concern was that I saw the CPU VID spiking up to 1.56 to 1.58, which would make sense to me since Turbo Core is set to run at 1.475, but it adds in my offset (same thing happens if I set voltage manually instead of as an offset btw) along with LLC. The temperature of the CPU does not increase perceptibly, which I assume means that the system is working as intended. However, I wasn't really comfortable about spiking that much voltage through the cores. I backed it down to a 4.0 OC, which I can stabilize at 1.3875 or so, and the Turbo Core only pushes up to around 1.55 now, which is a little better. My question would be, should I actually be concerned about the high voltage spikes, or since the temperature is still the same, am I ok? I can always tune down the Turbo Core VID with phenommsr or something, I suppose, but I thought I'd ask if you or anyone has done a lot of tinkering with Turbo Core and might have some insight.
Now I can run pc ok @ 4ghz with 1.4 voltage lol.
