Hi,
I recently built myself a Socket 7 system to pass a little lockdown-time. Now that I got it up and running and upon doing some benchmarks, I realize that my performance is pretty abysmal compared so similar setups...
Not that it matters a lot in a retro system, but I still would like to know if there is something crippling the system... some help/suggestions would be highly appreciated!!
Here are the specs:
Zida 5SVA Motherboard with VIA Apollo VPX chipset (PCI only), FSB set to 75 MHz
AMD K6-3 400 CPU @ 450 MHz (6 * 75)
256 MB SDRAM (set to CL2)
Voodoo3 2000 PCI (OCd to 3000 specs, i.e. 166 MHz Core/Mem)
Win 98SE running on a 128 GB SSD on an IDE-SATA adapter connected to a UDMA-5 PCI IDE controller (lots of adapting going on but atto gives me around 50 megs/s...)
For example, in 3DMark2000 I get a score of around 1100, whereas Phil from Philscomputerlab gets 1800 with a pretty similar setup, although he is running a K6-3+ at FSB 100 and 550 MHz.
Could the higher FSB and Clock alone account for this huge difference? I was initially running at 400 MHz, 66 MHz FSB and got a score of 1000 (vs 1100 now), so only about 10% improvement by raising FSB and Clock.
I think there must be sthg else going on... again, any comment is welcome!
