Despite listing support for up to 256kb cache and 32MB of system RAM, the board only seems to support 128kb cache and 16MB DRAM without becoming unstable. Newer revisions of the board may have BIOS and hardware support for Cyrix 486DLC type chips. The CHIPs PEAK/DM chipset provides brisk main memory performance, but sadly the bank interleave mode was not implemented on this motherboard.

Despite listing support for up to 256kb cache and 32MB of system RAM, the board only seems to support 128kb cache and 16MB DRAM without becoming unstable. This behaviour has also been exhibited on boards using the PEAK/DM chipset. Newer revisions of the board may have BIOS and hardware support for Cyrix 486DLC type chips. The CHIPs PEAK/DM chipset provides brisk main memory performance, but sadly the bank interleave mode was not implemented on this motherboard.

Latest revision as of 17:15, 23 December 2015

Despite listing support for up to 256kb cache and 32MB of system RAM, the board only seems to support 128kb cache and 16MB DRAM without becoming unstable. This behaviour has also been exhibited on boards using the PEAK/DM chipset. Newer revisions of the board may have BIOS and hardware support for Cyrix 486DLC type chips. The CHIPs PEAK/DM chipset provides brisk main memory performance, but sadly the bank interleave mode was not implemented on this motherboard.
