somehow, is no worky for me. i finally got it to a stable 4ghz but i have to increase VTT to 1.425v
i am not sure if i am compfy with that 24/7, how sensitive are these chips to high VTT's?
i usually go through a intelburnintest and linx session before i prime .. is that or

Ok here it is, example with OCCT CPU LINPACK 64 bit with HT on:

Here it's only 2 minutes for showing the requested data, after 1 hour the water temp is around 34-35°C with a air intake temp of 23°C, I was not in my private office this evening so it's cold in there, 18°C, brrr.....

In the EVGA tutorial, they talk about that:

* Bootup CPU VCore - 1.30000V (good for starting point, will likely need to increase for 24/7 stability)
* Eventual CPU VCore - 1.30000V (good for starting point, will likely need to increase for 24/7 stability.)
* DIMM Voltage - 1.65V
* Bootup CPU VTT - 1.400V
* Eventual CPU VTT - 1.400V
@ 1,3VCore, not stable with high CPU load. I increase the Vcore power until 1,36V and something using the ECP hardware control panel and it was working. What I do not understand is that the Vcore auto adjust during stress test, but anyway if I setup VCore @ 1,36V+, no problem with stability.

There is another difference with the tutorial: I use native PC16K memory modules, so I don't OC the memory, it's running @ 2000MHz 8-8-8-24 1,65V without OC, it's the reference setup for the GT.

Something happens when temps are higher, for example during a Power Supply test with OCCT: if I run a Prime95 8 threads, I get some errors on 3 cores. I don't know why, calculation stops on Core 0 thread 2, and core 2 thread 1 and 2. Maybe because temps or voltage are too high? Its not reported on the monitoring... never went over 80°C even after a hard time testing all CPu/GPU together.

Do you think the dual 8 pin 12V power connector on the Mobo may help for stability? My PSU is connected on both of them.
