If I read that right gals/guys, it sounds like he just told us that it works! WOOHOO!

See if you can set it to 33mhz x2 heck 33x3 may even work… 100mhz The overdrive and normal dx4s came in 100mhz flavors.

I don’t own one of those CPUs myself but from what I can see I would expect the performance to be similar (exact?) to a regular DX4 in the same motherboard Obviously you cannot run a DX4 in a five volt motherboard though Without an adapter

If you only used half your cache sockets that could also lead to slower performance sometimes

Perhaps it isn’t running in write back mode? Maybe FSB differences are to blame

Does speedsys say that it is running at correct frequency? Are you sure your cache is working?

Yeah, that’s pretty low freq. https://www.homemade-circuits.com/calculating-filter-capacitor-for/amp/ Maybe this helps? Btw, to those reading this in the future, what feiopa is seeing is potentially something specific to his system. Yours may have a different interference frequency from the parts …

It seems that no one knows. Suggest trying based on overclocking results or hooking a scope and calculating what caps to use. Plug! it! In! Plug! it! In! Plug! it! In!

Put the power supply pins on a scope once installed and analize what frequencies you are seeing. That will determine what capacitors you should install. (I think) Well, plug it in already! :p (but not before checking for shorts) As for shrinking it if you say there is room I can move stuff based on …
Re: Socket 1/2/3 Voltage Interposer Tweaker (Alpha, seeking testers)

I'd prefer everything to be on the interposer. Some people (myself included) do not want to have to do extra mods. Perhaps there is a way I can add it between the sockets while keeping the external terminals for those who wish to go that route.? 🤔 Gonna screw up the silk screen instructions though. …

I looked at the images from Earlier in thread to refresh myself, (I’m still away from computer) and if you want it smaller, the edge capacitors gotta go. Or, it will have to be a non rectangular shape. So options are: 1: Leave as is 2: irregular shape 3: smaller rectangular but ditch the edge caps I …

Yeah, I don’t think there is a way to tell from the back. Gotta plug in to see the type, but speed will only be printed on front I believe. So in bios it will be whatever you set/the chip supports. Unlike new chips where you plug it in and it is what it is, back then they didn’t have locks etc. so …

Do you think making it smaller will actually help on any boards? Are there boards with clearance issues that tight? I can understand it maybe hitting the fet side, but the sides?
