EpoX MVP3G2, MVP3G5, and MVP3C2 Motherboard
ATA/66 Hard disk Performance

Last updated:  4/14/00

4/14/00  So far the new BIOS is holding-up well.  It is not available on EpoX's web site, but is available from their FTP site at:
  ftp://ftp.epox.com/support/motherboard/bios/beta/vp3c0412.exe

4/13/00 In the Dux computer Digest reviews of the EpoX MVP3G2 and MVP3C2 Super7 motherboards I expressed disappointment with the ATA/66 performance of these otherwise superb motherboards.  There were some questions as to whether the poor ATA/66 performance was being caused by the VIA VT82C596B South Bridge chip, the BIOS, or the 5,400 RPM ATA/66 hard disk used in the benchmark tests.  This morning I received an E-Mail from a reader stating that 'EpoX has finally got a handle on their UDMA66 problem' and that a Beta release of the BIOS would be available on EpoX's web site.  I searched the site and could not find the BIOS.  I fired off a message to EpoX tech support.  Before the ink was dry on my message, EpoX responded with the BIOS attached.  Well, folks, the problem was the BIOS and it looks like it has been fixed.  I ran a quick set of benchmarks with the G2 board and a 500 Mhz K6-2, below.  In particular the HDTach HD Read Burst speed has jumped from 22 to 57 MBPS!   The WinTune 98 benchmarks also show a noticeable improvement in memory performance.  The new BIOS version is vp3c0412.bin.   Before proclaiming that the problem is indeed solved, I want to run the BIOS for a few more days to check for stability and run some more benchmarks.  I will revise both reviews when additional testing has been completed.  It looks like EpoX is finally the winner in the Super7 realm, and that the Super7 is far from dead.  Larry
