Yeah, I have had my x5670 for going on 4 months. I have had it overclocked to 4.2ghz all cores turbo (1.28v) with a 4.4 single core turbo. It has been rock solid, no crashes, and no blue screens. That is why this whole vtt thing was pretty strange to me. I had been running strong for so long.
I did have a few change points though, about 11-12 days ago I installed the 12gb gskill ram which I settled for 10-10-10 timing at 1750mhz. Then, about 6 days ago I set the command rate from 2t to 1t. That last change point, I tested very lightly in my book. Just ran some memory test and legit go.
So the fact it would boot with 1.255vtt all of a sudden was kind of strange and unexpected. It is strange because it just completely refused to boot with a 1.255vtt, but will boot 1.275v
Anyway, I share your extra bump for added stability rule. So, after I verified to the absolute best of my ability that 1.275vtt was completely solid. After stress testing and hard core gaming for hours, I did go ahead and bump up the vtt one more notch for that extra security. Not too long ago I bumped up the vtt one more notch which is 1.29v. This wasnt needed but I like the little bump for added stability rule. Afterwards, checking my temps. I did have a 2c increase on my hottest core going from 1.255 to 1.29v in vtt. I am still normalized under 70c but where I used to be steady at 64, I am now at 66c. Not a big deal.
It will work I guess.
I think my CPU has really good overclocking characteristics when it comes t the cores and clock speeds, but the IMC is probably not all that special, average maybe.
Anyway, that ram issue is really strange. I wonder if it is a CPU thing or a motherboard/bios glitch. According to intel, they are only rated to run1333mhz ram. Perhaps its just your CPU. I wouldn't worry about it much cause it seems like other than that, you have great results when it comes to vtt, uncore, and ram capabilities. So really its not something limiting at all, just strange
