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:



Then 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 LN2 insulation:

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.

Stuff paper towels in between DIMM slots, and you need to put paper or grease into un-used slots as well.

Only use a TINY amount of grease in-between the slots!

Don’t forget to put in your memory sticks.

Use the slots pictured below first as they are the first slots per channel.

Post 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.
