What is strange also is that it is when I set the RAM overclock and the RAM voltage at 1.35V that I see this phenomena.
If I only overclock CPU core and CPU cach and let RAM frequency and Vram on auto, my temps are much lower, even than with the former MOBO....

If someone would have an explanation....thumb.gif

OC'ing the ram will increase the load of the IMC, which is located on the CPU. This is reasonable to assume that your CPU temps increased due to your Cache OC'd to 4.5GHz and ram to 3200MHz, when compared to your previous results with the MSI board.
post #1633 of 6327
I have my cache OCed to 4.3GHz at present on my 5930K. It was higher until the summer temperatures made me drop it down. At any rate, I understand this is a higher OC for cache than a lot of people are using (though I see someone above is running 4.5), so I don't have a lot to go on from others. With it my RAM will operate at 3200MHz with 4x8GB. My strap is 100 at present so all OC is done with a multiplier.

From what I've read, I will need to use a strap of 125, which will mean I will need to lower both cache and core multipliers, but I'd like to know if I should aim for the current frequency for the cache with the 125 strap, or if I should expect the new cache frequency to be lower with the faster RAM speed? I'm guessing that I will have to lower cache frequency; I'm just not sure where that cutoff is, and if it's due to the chip itself (i.e. each chip is different) or some other factor(s). I'm also curious what sort of cache frequency drop would be required to offset the RAM frequency increase in terms of synthetic performance benchmarks.

cache from 39 to 45!! that's why the temps are higher.

Curious, what are your core and cache voltages for that 4.5/4.5? I'm assuming you're not actually maxing out at 1.17v for 4.5Ghz for the core and that's just downvolting due to adaptive, heh.

Guys, I just got a 6950X - will it support the Dominator Platinum 3466Mhz 64gb kit? The 'default' speed of RAM for this CPU is 2400Mhz but my 5960X which has default of '2133Mhz' right now is running my RAM at 3000Mhz.

Link to kit or part number would help. Could well be possible but XMP may require some manual tuning.
