June 18, 20224 yr I think it is possible to go slightly more higher by using a dual core Xeon 45nm. And you will need to keep the northbridge temp under 70c
June 18, 20224 yr I bought an X5260 E0 to try, maybe it'll help. Regardless this is far better than my other board which stopped at 415 FSB.
June 19, 20224 yr Author Your board is one of the last rev as me. Easely checkable with the skull logo stamped on the southbridge cooler. Rev 1 and 2 are only full black without logo. Let's see how far we could go^^

Rev 1 and 2 are only full black without logo. Let's see how far we could go^^ I did some more testing and it's definitely the board limiting fsb, tried numerous cpu's I had around but none got any further. NB volts & VTT do nothing to help, played with the GTL's and PCIE freq also. Seems like something behind the scenes is stopping it, hangs on post code 1P (which is nothing) which is just prior to 51 (Allocating resources to the PCI bus). Sometimes gives a memory error so maybe the 5:4 mem strap is doing it, maybe I need FB-DIMM's that can do 450MHz+ @ 1:1.
June 20, 20224 yr Author Possibly the fb-dimm, did you tested with one stick of 1gb dual ranked 1.8v or the very rare 1.5v pc2 6400 fixed in auto ? PCIE freq from my board won't boot above 101 1:1 in think is limited to max ~425-430 in quad channel
June 20, 20224 yr Have you tried CPUcool instead of setfsb? Gained me around 20 MHz FSB for valid on my Supermicro.
