From the two 1.25 GHz dual processor daughtercards that I now have loose here, neither one is an 820-1452-A like yours. The closest one is an 820-1472-A. And I’ll attempt to attach that large image (approx. 20” x 22” / 6.47mb / 1440 x 1570 pixels) below, in case that might be of any use to you.
Now, I also do have a “stock” original, 2003 MDD 1.25 GHz DP here, that may have the same “two coil” daughtercard AND also may be a 820-1452-A — but would have to pull it and check… which might be later this coming week.
In the meantime, perhaps you might instead, seek an MDD 1.25 GHz single processor daughtercard (820-1497-A ©2002) as they also have the “two coil” configuration and therefore might not require a different heatsink from what you now have. AND you would still maintain the MDD 1.25 GHz speed.
Yours is a two-coil?
So there’s another possible option… until you can repair your 820-1452-A?
