Speedy22 Posted June 18, 2022 Share Posted June 18, 2022 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 Quote Link to comment Share on other sites More sharing options...
DR4G00N Posted June 18, 2022 Share Posted June 18, 2022 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. Quote Link to comment Share on other sites More sharing options...
Speedy22 Posted June 19, 2022 Author Share Posted June 19, 2022 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^^ Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...
Speedy22 Posted June 20, 2022 Author Share Posted June 20, 2022 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 Quote Link to comment Share on other sites More sharing options...
ground Posted June 20, 2022 Share Posted June 20, 2022 Have you tried CPUcool instead of setfsb? Gained me around 20 MHz FSB for valid on my Supermicro. Quote Link to comment Share on other sites More sharing options...
