Memory LN2 OC:
With the Z77 platform it may be necessary to LN2 cool the
GPU or the memory. This might be one of the first platforms where LN2 cooling
the memory might be necessary to get WRs, and you might have to do it not on the
newer memory such as from Samsung or Hynix, but on older kits such as PCS which
can do tight timings up to 2800mhz where they are superior. Speed while very
important for this platform, also needs to be complimented by nice timings which
can occur when under LN2.
My LN2 OC procedures:
I tend to boot into Windows at -80C with 110.00 BCLK and 55x and 1.7v,
I will then get into Windows and boot up CPU-Z and GTL:
I will increase the multiplier and until I am at a point where I can slightly
raise other volts and BCLK until where I want them. The GIGABYET Tuning utility
and EasyTune6 both change settings very easily, but GTL is easier to use and is
lighter than ET6, its whole purpose is Extreme Tuning. I can then proceed to
tweak the timings, run a benchmark, then increase a few more MHz and run it
again until I am happy.
Tips for Memory
Use Vaseline or little bit of silicone grease in the DIMM sockets, but
be careful as too much grease can cause lower memory OC because of the fact that
it gets in between the contact pins to the memory. A light coating should be
enough to not cause issues. If it does cause issues Vaseline can be melted away.
paper towels in between DIMM slots, and you need to put paper or grease into un-used
slots as well.
use a TINY amount of grease in-between the slots!
Don’t forget to put in your
the slots pictured below first as they are the first slots per channel.
Code 15 or 51 could be memory OC related.
LN2 helps the IMC
The memory gets
cold even without any pot on top of them. If you have a fan blowing air up away
from the board, then you shouldn’t get all this frost you see.
