I updated the diagram top show the WB/WT mod also.

Socket 7 and usb 2.0 are a bad mix better to use a hub on the usb 1.1. If you install a card and run 3dmark (nothing using the card) then pull it out and run it again you’ll see what I mean. Could mean 1/3 to 1/4 better score Thanks. OK, that is weird. Sure it applies to all chips? I've read the …

Okay, with latest developments in the tillamook thread I am more fully understanding this, https://www.vogons.org/viewtopic.php?p=1053825#p1053825 It seems, You want to be sure that BF0, BF1, BF2 all show about 330 ohms or so to VCC3 (3.3v) I believe that will solve some of the issues that some …

I’m contemplating figuring out how to add 3 register multiplier support to the s1564. I assume any mod would only be needed on cpu0? Or will it be needed on both? Prob both for bf2 right? As probably not connected? Socket 5/7/SS7 (Motherboard) Tweaker (Released)

I managed to find VA-503+ couple of days ago and it came with the USB riser card. I wouldn't have guessed that the riser card is rare. I just assumed it was included with every motherboard. Those are probably rare AF since they only ever were optional in retail boxes, as stated in the manual: 2022- …

Some bios editing utilities can enable hidden Settings. Awdbedit I think is one, but I’m told it corrupts. I think it would be really cool to make a socket 3 to socket 7 adapter.

I know Hondabond will not absorb petroleum products and swell up and break down like silicone will. It is way higher quality than any of the other automotive silicone sealants I have used in the past 25 years. Not sure that trying to have a sealed ring around the core is a great idea. For one, …

You all are way overthinking what to use to reattach the IHS. Silicone glue will work just fine. If you want something that is way closer to the look and feel of the original glue, go buy a tube of HondaBond from your local Honda dealer. As a collector, I feel it’s important to use the best stuff, …

I put the shield back on with Arctic Silver 5 and four dabs of super glue. The result was counterintuitive; all else was the same, but the temp was noticeably cooler. I then decided to swap to the best Socket 7 heat sink I have. Unfortunately, the super glue didn't hold (the shield stuck to the …

It ocurs to me that there are a few boards out there that seem to demonstrate that at the very least a socket 4 to socket 5 adapter is possible.
