SiS 611 is slower than 411 for what i know. 611 is PIO-3 only. 411 with driver can reach PIO-4 speeds for reading at least. Never saw SiS 83C601 chip or card based on it. Do you have any available photo reference ? Attached PIO-4 enabler for UM8672F.

Very cool. I was unable to make the Zida board do well at 60/66MHz FSB. Was thinking to give it another spin soon. 3-2-3 cache timings is going to be slower than no cache in the most cases. As you said early - you should check the Zida without L2 cache. Btw, you don't have to post multiple …

Must go in one batch. Dark SOJ chips are 10ns rated.

@feipoa I discard 20/25ns chips entirely for two reasons. 1. It is unlikely somebody relabeled faster chips to slower. So, most likely they are what the label says. 2. Have enough 10-15ns ones to test with. Within the 10/12/15ns group, both DIP/SOJ, there is no apparent pattern to follow, or at …

@gonzo Getting a 486 system maxed out and fully stable at 180/200mhz can be a frustrating experience. It is up to you how far you want to take these old components. As others say - journey is the mission. If you are satisfied today with what you got - leave it there. Functional L2 cache can be …

Very cool @jonf. Share a photo of the memory module. 32mb at "fastest" is rare, unique i would say. I think this alone gave you the +0.1 fps. Will update the charts for your achievement here. @feipoa At 3x66 1/2:1 is the only way to stability for LSD and similar boards.

@feipoa Ok, you are seeing it too. Latency ratings don't matter. Simple as that. The market is contaminated hard with such chips from who knows where. Makes it impossible to reason about anything. Anyhow. With that said 8ns SOJ SRAM for sure scales better than anything in DIP-28/32 package. So, it …

How confident you are that they source from trusted suppliers ? Price is the sole factor for such commodity products. Asian businesses are well positioned to dominate the field. It is easy for me to imagine cool-brand western resellers tapping into them. At least i cannot think for an easy way to …

Agreed. DIP-28/32 SRAM speed ratings are completely meaningless now-a-days. This topic keeps coming over and over again. We have to establish 2 short sentences answer to it: Forget the ratings. Trial and error is the only way.

Yes, L2 cache is the main obstacle for 486 overclocking. The DIP28/32 chips just don't scale well to meet the requirements of 60/66MHz FSB and tight BIOS timings. It takes quite a bit of time and effort to curate pile of chips into few well working sets. Time to seriously consider SOJ-to-DIP …

Ok, L2 cache seems to be back in action, but reduced to 128Kb. With 15ns rated chips the 2-2-2 timings is actually very good, but the smaller buffer is helping there. L2 cache is always the weakest point for 486 overclocking past the 40MHz FSB. If you can - spend some time to rotate the available …

Very cool @gonzo. Did you target the SYL8884PCI-EIO motherboard because of that other thread you linked, or it fell in your lap by coincidence ? It looks like a late budget version when the world moved or was moving en masse to Pentium. Most of these assemblies are not very fast on a clock to clock …

Okay. My search-fu failed. No idea how you related the Lynx board to Epson Equity line of computers, but i appreciate it. Especially the scanned manual. I am going to touch-up what i wrote early. Thanks.

@Irinikus Do you think you can run the Q3 test (SMP enabled) with both Q FX3000 and FX4000 ? Want to see if the CPUs can keep FX3000 busy enough. Thanks in advance.
