Hi,

I have been looking into building a new flight sim rig coming from an old Sandy Bridge system and have been reading up about the enhanced multicore boost function that is controlled via the motherboard instead of using the Intel Turbo Boost found on Intel i7 "K" CPUs and have a few questions for those that have overclocked their Intel CPUs and their experience with this function.

 

1. Is there a big benefit to running the motherboard-based multicore boost that allows you to clock all cores at the max Turbo CPU frequency (same multiplier applied to all cores)  versus the Intel Turbo boost (which clocks the 1st core at max but the remaining cores at lower frequencies depending upon load)?
2. Is there a significant advantage of using the Dynamic vs Fixed mode of this enhanced multicore boost function?
3. Is there one brand of motherboard that can handle this better? So far, I have read Asus, MSI, Gigabyte and ASrock all pretty much provide this same functionality.
4. Does this ultimately make a noticeable difference to FSX or P3D in real world performance at the end of the day versus the Intel Turbo boost?

I have also read the disadvantage is the cores will of course run hotter with all cores clocked at the same multiplier so a good cooling solution is needed.

I'm interested in your thoughts and experiences here.

I would say that depends on the application. You would need to know how the application behaves in regard to core usage. Which cores it utilises. In some applications you may find no advantage. In others, that utilise all of the cores equally I would assume you would.

I have no idea what that is. I use Asus boards that either have MCE on or off.

As someone that's used Asus boards exclusively, I can say that I find the implementation of MCE to be very good. The only thing I will say, and this applies to all makes, is that the manufacturer will apply auto voltage to handle the fact that all cores are at the max turbo frequency. Now there's no way a manufacturer can know how a CPU fairs in terms of the silicone lottery, thus, additional voltage must be applied to handle the worst case scenario. For this reason, for most, the voltage will be more than required. Heat is then generated that those with sub standard cooling might find excessive. 

I can't answer your question regarding flight sim performance as I'm not simming these days. But in regard to cooling, as long as you have a reasonable cooler you should be fine. I think the cooling solution would need to be from the bottom of the back for it to be an issue.

Thanks.

Much appreciated.
