Description Apollo VP3

zida tomato 5dlx motherboard via vp3 chipset (512 kb sram, 2 dimm-s, 2 simm-s, 1 agp, 3 pci, 2 isa )

apollo vp3 supports 32 bits socket 7 cpu-s, pentium, pentium mmx, amd k5, amd k6, cyrix 6x86, winchip c2 , c6 cpu-s. uses vt82c597 (or vt82c597at baby @ , atx motherboards) northbridge controller chip , ac97 compliant vt82c586b southbridge chip acpi power management system. vp3 has 64 bits memory bus; 32 bits 33 mhz pci; 32 bits 66 mhz agp 2x sideband addressing, 133 mhz signalling , 533 mb/s transfer capability interfaces. uses integrated 10-bits tag comparator , supports 2 mb pipelined burst synchronous sram (cache memory) , 1 gb ecc cachable ram memory. memory controller supports 8 memory pages (banks) interleaving mode, flexible row , column addresses, concurrent dram writeback, read around write capability, burst read , write operations, etc. (for more details see). officially, supported speeds of memory bus 50, 60 , 66 mhz, numerous implemented motherboards vp3 have 75 , 83 mhz bus speed capability.

vt82c597 northbridge supports 6 memory banks of dram-s or dimm-s 1gb in total size. memory controller supports standard fast page mode (fpm) dram, edo-dram, synchronous dram (sdram), , sdram-ii double data rate (ddr) in flexible, mixed configuration. synchronous dram interface allows 0 wait state bursting between dram , data buffers @ 66 mhz. 6 memory banks of dram can used in arbitrary mixture of 1mb / 2mb / 4mb / 8mb / 16mbxn dram or dimm modules. memory controller has 3,3 v (5 v tolerant) interface.

vt82c586b includes udma-33 eide, usb, keyboard/ps2-mouse interfaces , on chip rtc plus 256 kb cmos.

anandtech described apollo vp3 being combination of via apollo vp2 , intel 440lx chipsets.

apollo vp3 quite shortly replaced via apollo mvp3 chipset, offers faster, 100 mhz memory bus capability , asynchronous memory bus, supports less amount of cachable memory area , system dram (only 4 memory banks). lack of 100 mhz bus support, needed newer amd, cyrix, etc., super socket 7 processors pushed via drop vp3 production.
