HP Kayak XU Series 04xx and HP Kayak XW Series 04xx Cache Memory 512 KB or 1 MB of level-two cache memory is integrated in the Pentium II or 2 Pentium III Xeon processor package. Main Memory The PC Workstation has four DIMM slots on the system board for installing main memory; slots Mem 1, Mem 2, Mem 3 and Mem 4. Models are supplied with 128 MB of unbuffered main memory. If additional memory is required, up to 1 GB of unbuffered memory may be installed. Memory upgrades are available in single 64 MB, 128 MB or 256 MB unbuffered ECC SDRAM modules. Or, alternatively, replace the existing unbuffered memory modules and install Registered ECC SDRAM memory modules. Up to 2 GB of Registered memory modules may be installed. A serial EEPROM on each DIMM contains data on the memory speed. This information is read at each power on, and access time settings are set accordingly. NOTE: Registered ECC SDRAM memory modules are not compatible with unbuffered ECC SDRAM modules. Therefore, memory can be upgraded to a maximum of 2 GB using only multiples of 512 MB Registered ECC SDRAM modules (4 x 512 MB). Video Memory on Kayak XU Series 04xx The graphics controller installed on the PC Workstation could be either a Matrox Productiva G100-Quad, a Matrox Millennium G200, an AccelGalaxy AGP or an ELSA GLoria Synergy+™. The Matrox Productiva G100-Quad graphics card can support a multi-monitor environment allowing for a custom-configured display solution of up to four monitors at a time with a total of 16 MB of video memory (4 MB per monitor). There are three possible configurations: horizontally, vertically, or in a square. The Matrox Millennium G200 has a 8 MB of SGRAM memory already supplied on the graphics controller board. Memory may be upgraded to a maximum of 16 MB by installing a 8 MB SGRAM memory module onto the board. The AccelGalaxy AGP Graphics card has 31 MB of video memory already supplied on the graphics controller board, which cannot be further upgraded. This card is supported only on the Windows NT operating system. Drivers do not exist for Windows 95 nor Windows 98 operating systems. 2-10 HP Kayak XU Series 04xx and HP Kayak XW Series 04xx Mini-Tower PC Workstations
