MSI 745 Ultra disable SSE a.k.a. 3Dnow professional ???

[dnmt]

I've just switched my mainboard to 745 Ultra (SiS745) a few days a go, only until today I have found that my Duron 1ghz (morgan) suddenly don't have SSE support, I've checked it with wcpuid, sandra, 3dmark 2001, they all say my duron morgan support only MMX, 3DNow, extended 3Dnow. No SSE at all. I went further and test it with games, I use CnC renegade and UT, in the game log written SSE: no.

I'm 1000% sure there IS SSE support before I changed my mobo to 745 Ultra. Before this I'm using Chaintech 7VJDA (VIA KT266A).
I'm using 2 OS, win 98 SE and Win XP, both shows the same result NO SSE.
Anybody with Duron morgan / Athlon XP and 745 Ultra have the same issue like I do? is it just me? or maybe my duron is broken?

If I'm not the only one w/ this problem than MSI you've got a big big big problem, better fix it ASAP.

pretty sure (might be wrong tho) that durons dont have SSE. ONLY athlon XPs do........

Anyways. U went from a kt266a to a sis745???

was there something wrong wtih your kt266a? cause you just downgraded performance wise.

Yes, the Morgan-core Durons definitely do have SSE support.

It is supported in my old mainboard, I'm very very sure about that.

going from KT266A to Sis745 mmmmmm......I fried my KT266A on some experiment with WPCRedit
actually this board is overclocks much better than KT266A, it can go as high as 175MHz both memory and FSB, with chaintech KT266A, all I can get is 150MHz with overclocked PCI and AGP bus.
