WOW that's good. What mb and ram with that 5960X? Do you have it at 46x100 or did you raise your blck to 125?
The motherboard I have is the MSI Godlike, and I'm using a straight multiplier here because BCLK is giving me less-than-stellar results. I don't want to derail the thread with non-watercooling stuff, but...
The RAM I purchased is advertised for 2800MHz. Unfortunately, I didn't realize that 2800MHz isn't a real "step" of memory speed, and the XMP profile sets the BCLK to 127MHz with the RAM at 2200MHz (or something similar) to reach the advertised 2800MHz. I say "unfortunately" because with such a high BCLK I can't seem to get the CPU to overclock reliably at all.
So, I dialed back the BCLK to 100MHz and the RAM to 2400MHz because I wanted to see what my chip could do by just playing the multiplier. After some quick testing I figured out that it likes 4.6, since 4.7 required another ~.6v in order to get it to run more than 30 minutes on a stress test. That extra .6v raised temps an additional 10C to almost 80C, which I wasn't happy with.
I then tried to mess with the BCLK a bit to see if I could increase the speed of the RAM while keeping the CPU around 4600MHz, but for some reason when using the BCLK to overclock the CPU it wants to use a lot more voltage than when the BCLK is set to 100MHz. This obviously raises temps, again.
It seems like 4.6GHz is where it's at, and anything beyond that is going to require more finagling than I'd really care to participate it, especially when stress testing takes forever. The only thing I'm trying to do at the moment is get the RAM to run stable at 2666MHz, but I'm continuously failing to do that and I'm not so sure I want to pump a bunch of voltage into my DIMMs for a measly 266MHz.
...maybe if they were water-cooled.
EDIT: Since guskline mentioned it, I decided to look a bit deeper into HW-E overclocking via BCLK, I decided to try it because I was reading that reaching RAM speeds over 2400MHz was very difficult w/o BCLK. So, I decided to set the BCLK to 125MHz (not the oddball 127.xx that the RAM's XMP profile used), and I was able to set the RAM to 2666MHz (using 2133MHz as a starting point), and the CPU to 4625MHz (37x125). So far, I'm 2.5 hours into stress testing this and so far, so good. Like I said above, using BCLK seems to suck more voltage and right now it's using between 1.304v and 1.312v, which pushes the temps up to 74C - 75C while under full, constant load. I don't know if I'm going to stick with this
since I'm not entirely sure what the consequences are for the rest of the components when using such a high BCLK, but we'll see.
