Then I can add in my info for comparison:

For 2 cards in parallel flow at 1 GPM, with both 25 mV switches on and +63 from P-X on the EK acetal/nickel block with 8x 120mm rad space with SP120 fans at an ambient of 25-26 C:

1) With MX-4, the max was 44 C
2) With PK-3, the max was 43 C

So in a pretty similar state as Marc's, there is a difference of about 2 C which can well be attributed to the higher rad space and fans as well.

Many have said around 1.65 to 1.7 max volt on mem for water.
I went personally up to 1.8V on water at -20C and seen gpu temps increase a few degrees from 1.7V to 1.8V

Thank you a lot! smile.gif
What should be a reasonable frequency for 24/7? Now I'm @7600Mhz 1.72V

I did many tests in these days and I found another game (there is also "Tomb Raider") that pushes strongly the card, it's "Shadow Warrior". In my opinion an hour of this one or TR is better than 3 hours of Crysis 3/ Metro LL wink.gif

Yes, Tomb raider and Far cry 3 are better memory OC stability than Crysis 3, this last one is better for core OC testing.

Yeah! What about my memory OC? Do you think that can I go higher? (7600Mhz @1.72) smile.gif

I personally only use above 1.6V for memory for benching and have not really seen much improvement by setting. 1.8V
To run 1.72V 24/7 i would chech vrm temps in gpu-z.
Hopefully some folks here can comment on their experience for oc'ing memory and increasing memory voltage for 24/7 usage.

7600 is really good if you are with tight timing (I suppose you are with that voltage), it's what I was able to do with loosen one on stock voltage if I recall.
edit: I personally can't go with the hassle to run and setup the classy tool at each startup so I won't be using it for daily use.
