Without the modification described in this thread., some people hear this peak.
As you use PCB R5d you already have step 1,2,3 done by just soldering the 22ohm OLED resistor, so the peak is smaller that it was on PCB R5c.
If you make a shield as described it will be even smaller.

Just a quick question on the aluminum shield mod:  Do you just stuff the bag between the OLED screen and the PCB?  Do you secure it all?  Is it okay if the bag is touching the board?

As far as only plastic touch the board it's totally OK.

I definitely noticed the squeak after upgrading to OLED, but the shield fix was easy and effective. No extra soldering needed with the recent board revisions. Thanks Xavier.
