Korg Sampling RAM Module for PA800, GRA0002101
Sampling RAM chip for PA800. 64MB SDRAM EXB SODIMM 145
DISCONTINUED, NO LONGER AVAILABLE
Any of the following types of symptoms could be an indication of bad SDRAM within the PA800.
- Distorted output.
- Sample memory is not showing up on the sampling info screen. More details are available at www.korgpa.com
This can be checked by pressing [SOUND] followed by [RECORD], and then selecting the "Sampling Info" tab on the screen.
- The Test Mode indicates a RAM error.
The PA800 has two banks of SDRAM. Bank #1 consists of a number of ICs soldered onto the CPU board. Bank #2 is a removeable SODIMM module installed into a socket on the CPU board. Use the buit-in diagnostic test to check the SDRAM and determine which bank the problem is in.
A message indicating an error in bank #2 (Ram Bank 2/2 Buss Error) can safely be assumed to be a problem with the SODIMM module. Replacing the module. (part # GRA0002101) should solve the problem.
- A message indicating an error in bank #1 (Ram Bank 1/2 Buss Error) can be a problem with either the on-board SDRAM, or with the TGL IC that interfaces to this SDRAM. Inspect and/or replace the on-board SDRAM, or replace the CPU board if a bad TGL is suspected.
