SIMMConn User's Manual
Introduction of SIMMConn
SIMMs that can be used on SIMMConn
Thanks for using SIMMConn adapters. Please read this user's manual carefully before installation and keep it for future reference.
SIMMConn is an adapter which connects a standard 72-pin Single In-line Memory Module (SIMM) to Sound Blaster AWE64 series sound cards. It is a low cost solution for upgrading memories on the sound cards. Two types of SIMMConn are specifically designed for AWE64/AWE64 Value and AWE64 Gold: SIMMConn Value is designed for AWE64 and AWE64 Value. The on-board 512KB RAM will be disabled when SIMMConn Value is installed. SIMMConn Gold is designed for AWE64 Gold. The upgraded memory will work as an extension to the on-board 4MB RAM. SIMMConn has lower cost and power consumption, but it may occupy some installation space of the ISA card next to the component side of the sound card.
72-pin EDO or Fast Page Mode SIMMs can be used on SIMMConn if their access time is equal to or less than 60ns. The memory part numbers listed in the following tables are examples. There are no brand name limitations for SIMM or memory chips used on the SIMM. Different types of SIMMConn have additional requirements to the SIMM. They are listed as following:
('Part No.' is referred to the memory chips used on the SIMM. 'Structure' is the logical structure of the SIMM, which may be different from the physical structure of the SIMM.)
|SIMMs for SIMMConn Value|
|Size||Structure||Chip Quantity per SIMM||Part No. (example)||Jumper Settings|
|16MB||Single Sided||8 (2k refresh)||HY5117403B||1-2||2-3|
|SIMMs for SIMMConn Gold|
|Size||Structure||Chip Quantity per SIMM||Part No. (example)||Jump settings|
|8MB||Double Sided||4 or 16||See table above||2-3||1-2|
|16MB||Single Sided||2 (4k refresh)||64Mbit Chips**||1-2||1-2|
|8 (4k refresh)||HY5116403B|
|8 (2k refresh)||HY5117403B||1-2||2-3|
|*The maximum memory
available is 28MB when a 32MB SIMM is installed. This is due to the limitation
of E-mu8000 synthesizer.
**We do not recommend using SIMMs assembled with 3.3V memory chips without an on-board voltage regulator. It may cause over-heating and reliability problems.
If the Structure/Chip Qty combination of your SIMM is not listed in the tables, it may or may not be supported by SIMMConn. Please try jumper settings for similar sized SIMMs. If a SIMM is incompatible with SIMMConn, only 1/2 or 1/4 of its native capacity may be available.

upgraded memory is correctly recognized but there is
"pop" noises when play MIDI. It
is getting worse when playing.
