The Contact Frame from Thermal Grizzly and Roman “der8auer” Hartung is, as the name suggests, actually just a frame that replaces the ILM of the LGA1700 socket. Intel’s clamping method with only two contact points on the side of the IHS is replaced by a solid aluminum milled part that presses the CPU evenly into the socket on all sides and is thus supposed to prevent bending.
The scope of delivery includes only the frame, a T20 Torx key and the instructions in paper form. As you can already see, this here is not a completely new specimen, but a loaner from a good acquaintance. I therefore apologize for the slight signs of use.
The 4 existing screws of the ILM and the packplate are reused. With the help of the 45 ° markings around the screw holes, the torque of the screws is meant to be adjustable.
From below, you can see where the frame will later rest on the offset edge of the CPU’s IHS. Actually, the principle is simple, but the tolerances when mounting in an LGA socket should not be underestimated. The fine-tuning required for this during development is also supposed to be one of the reasons why the frame only came to the market relatively late.
The assembly itself is also very simple, although here, too, it depends on the subtleties. At first it is recommended to leave the CPU in the socket to protect the pins. Afterwards, the frame only needs to be tightened evenly. A torque of 0.03 – 0.06 Nm is specified for this, but in practice this is probably not measurable or realizable in most cases.
In his video on the frame, der8auer gives the advice to first tighten the screws between thumb and index finger and then to continue turning them exactly 90 °C using the markings. In my tests, however, this was already too much contact pressure, which resulted in instability of the DDR5 OC – more about this on the next page. Instead, it has worked best for me to really only tighten the screws so lightly that they just don’t come loose on their own. If the frame can still be moved back and forth minimally on the CPU without the screws turning, the RAM also still works like with Intel’s standard ILM – less is more here.
