Description
The DIMMCHECK 72P PRO(p/n INN-8558-3) enables SIMCHECK II to test 72-pin SO DIMM (36x2 pin Small-Outline Dual-Inline-Memory-Module) modules with basic configurations of 18, 32, and 36 bits. The test can be selected by the user at 5V or 3.3V.
The DIMM module (JEDEC MO-160) has an internal architecture similar to the JEDEC 72-pin SIMM standard with the main differences being the arrangement of the 72 pins along a double sided 36x2 edge connector and the use of TSOP DRAM chips which results in a remarkably thin package. The DIMMCHECK 72P PRO is conveniently installed in the 40-BIT expansion slot, and is automatically recognized by SIMCHECK II. All memory cells are fully tested, with a parallel write/read operation. The test procedure is similar to the regular module test.
Required SIMCHECK II Firmware Version: 1.25 or above

Operation
This tester connects to SIMCHECK II via the 40-BIT expansion slot. Plug the adapter into the expansion port only when SIMCHECK II is off.
CAUTION: Failure to turn SIMCHECK II OFF when connecting or disconnecting the DIMMCHECK 72P PRO may result in damage to the PAL chip of the DIMMCHECK 72P PRO!
INSERTION: The DIMMCHECK 72P PRO uses a vertically mounted YAMAICHI test socket with two ejectors that need to be opened prior to insertion. Carefully insert the DIMM into the socket, pushing it evenly along its top. When the DIMM is properly inserted, the ejectors will snap onto the semi-circular notches on each sides of the modules.
REMOVAL: The DIMM is easily released from the socket by pulling both ejectors sideways.
NOTE: DIMM insertion and removal should be done only during STANDBY mode.
Turn SIMCHECK II ON once the DIMMCHECK 72P PRO is installed in the 40-BIT expansion slot and insert the first DIMM module. THERE IS NO NEED TO SETUP SIMCHECK II, as it automatically recognizes this tester. After the first DIMM has been tested and SIMCHECK II returns to the STANDBY mode, the presence of the DIMMCHECK 72P PRO is recognized.
5V/3.3V VOLTAGE SELECTION: The DIMMCHECK 72P PRO can test the DIMM modules at either 5V or 3.3V. When testing a DIMM module, you can easily change the default 5V voltage setting to 3V by changing the voltage on-the-fly. This can be accomplished by pressing the F2 key during the Basic Test and then selecting the 3.3V voltage setting. This new setting will affect only this test procedure, therefore subsequent modules will be tested at the default voltage setting of 5V. The 3.3V setting can be set for continual 3.3V tests from SIMCHECK II's setup program, please consult your owner's manual for more detailed information.
3.3V vs. 5V TEST: You can distinguish between a 3.3V DIMM and a 5V DIMM by the length of the lower tab near pin 1. The 3.3V DIMM's tab is 3-3.3 mm long while the 5V DIMM's tab is 6.2-6.5 mm long. Most 5V DIMM modules will still be testable at 3.3V, but you will notice a large decrease in access time at the 3.3V tests. A 3.3V DIMM module can still be tested at the 5V test without damage, as most 3.3V DRAM chips are "5V Tolerable". You will still notice a better speed at 5V than at 3.3V, but the difference will be much smaller than with the 5V DIMMs. Future DIMM modules may come with 3.3V devices which are not 5V tolerable. Such devices should be tested only at the 3.3V setup.
