I believe it should be jumpered on 1,2+5,6. I found where someone else installed the 1.5 GHz CPUs in their machine and that's what they had set. I'll check mine in a minute.

Edit: Yep. 1,2+5,6

Ok, so at least the configuration is valid. What about your P/Ns?

According to <URL url="https://www.serverworlds.com/sun-375-3325-v240-motherboard-2-x-1-5ghz/">serverworlds, PN 375-3325 is the board for 2x 1.5 GHz CPUs.

Ok thanks. This (system board) P/N is used in multiple combination P/Ns (i.e. 375-3344 (V210/V240) with 1 x 1 × 1.336GHz US IIIi, 375-3345 (V210 only) with 2 x 1.336GHz US IIIi and 375-3346 (V240 only) with 2 x 1.503GHz US IIIi) and I wonder if perhaps the combination P/N also determines the available multiplier settings.
And if e.g. your V240 would have a 375-3325 system board with e.g. 375-3344 combination P/N and is currently running two 1.5 GHz US IIIi processors (so was upgraded some where in time), it would indicate, that this is not the case. I.e. one could than assume that all 375-3325 system boards allow for operation with 1.5 GHz US IIIi processors. I'm asking those details because <URL url="http://www.imhans.com:1004/syshbk/Devices/System_Board/SYSBD_SunFireV2x0_CPU.html">this page gives the multiplier settings for the V240/V210 system boards, but apparently these are not valid or not all settings are available for all system board P/Ns, e.g. not for mine which is a 375-3148.
