Hey,

Thought I would share my experience of testing my Asus VL/I-486SVGOX4 with an AMD 5x86 133 and 30 pin simms. This board very similar to the VL/I-486SV2GOX4 but features 30 pin simm slots which I think is pretty cool. I was curious to test if using 30 pin ram performed any differently to 72pin and if the same timings could be achieved. The board has 2 x VLB slots, no integrated I/O, is based on the SIS 471 chipset and has a PS/2 mouse port header. My board is the X4 version which has circuitry for 3.3 volt CPUs

My board is an older revision 1.2, I couldn't find jumper pin information anywhere online, Revision 1.5 has extra rows of jumper pins and I couldn't find any patterns when comparing which jumpers might correlate to what. So it was just trial and error. I managed to get it all up and going and system has been stable so far.

I can confirm VL/I-486SV2GOX4 bios versions work on this model and include support for the amd 5x86 133

I couldn't find any other threads where this board was paired with the 5x86 133. Turns out the board preforms quite well as per attached photo quake returned a result of 14.3 FPS and doom 1429 realteks.

Tests were performed with a VLB ARK 1000 VL video card and 16mb of 30 pin ram. I found Fastest bios settings were not a problem with either 72pin or the 30 pin ram.

Enjoy 😀

In a different mothrboard (with opti895 chipset) I found that 33MHz FSB at the tightest timings is not too far fetched, not even with 30-pin SIMMs.. The dividing parameter set was 40MHz/fastest. Hardly any 4x4MiB sets could do a problem-free Goldmemory at this height, but strangely it seemed much easier for 4x1MiB sets.
But a DX4-capable VLB board deserves its 16MiB, doesn't it? I may run into games or demos with it that don't find 4MiB enough. I also like to use disk caching sometimes.

As for 72-pin modules, I found it easier to pick 40MHz/fastest capable. But I had no such luck at 50MHz/fastest, let alone the cache chips that could do it. I don't have a single set for that speed.

Shame on us, doomed from the start
May God have mercy on our dirty little hearts
