The 3 green lands on the side are for MSID (Market sector id) pins. The result looks completely horrible but. Since the VCCIOPLL foil mod 'stuck' and worked as expected I didn't feel a need to replace it with solder. I did try very hard to superglue both cleaned up copper tape and tin foil but in the end the top (VID) block of the mod refused to work properly so I gave in and soldered a piece of wire through all of them, heh. You could also use copper or aluminum tape but the roll I have didn't have conductive glue so it was useless here. In my case, since I'm not spending $20 on a new mobo I'm also not spending $15 on conductive ink. It's the best solution if you have some at home. Connecting them together is a horrible experience. The green lands should be connected together, the red one should be masked. Thanks and credit goes to the original author of this mod who I couldn't really track down due to the first forum of it's appearance having disappeared (from what I could tell).

And the above info came from pinmodding posts I already found on random forums so I knew how to proceed. Worst case scenario I break some cheap hardware. This is about the first time I considered just giving up. But it should not be connected to ground anymore.

They are right next to each other, but VCCIOPLL is not connected in the older system.

The VCCIOPLL pin has replaced the VCCPLL pin.

Thus the VID code supplied by the chip can't be used directly by the mobo.

The number of VID pins (thus the bit-length of the VID code) that specify the VCore requirements of the CPU has increased from 6 to 7-8.

It turned out the main reason the mobo didn't support Conroe CPUs is that the Conroes use a slightly different power system design. There's an A2 revision of the board that handles Conroe cores, maybe success is just a bios mod away? It was essentially limited to the old Pentium/Celeron D power hogs. The Fujitsu mobo couldn't handle the Conroe CPU. I've decided to get rid of the Prescott to improve the situation so I got a cheap Celeron 420, which is Conroe based and has about half the TDP of the Prescott.Īs is usually the case there was a reason for the hardware being extremely cheap. I was getting over-temp warnings from the Ultrium drive from time to time, which does a fair bit of heating on it's own (though not as much as the CPU) The overall power consumption of the system was around 90W. As it turned out the Celeron was in fact Prescott based so I was looking at 56C idle temps despite 1 large fan strapped onto the heat-pipe CPU cooler right next to the large PSU fan. So not really giving it much thought I got the cheapest stuff I could find: a Fujitsu D2151-A1 mobo with a Celeron D CPU. I've decided to severely cheap out on the hardware for this machine since I only use it a few times a month. I have a dedicated PC for my Ultrium drive.
