No I don't have either I had the GA-M55SLI-S4 but it died and I was wanting to replace it but still keep all my original stuff (8GB ddr2 mem. 2X IDE dvd burners, video card, and sound card) but still get a little upgrade in the chip thus the 3.3 dual core so I liked the GA-M57SLI-S4. However if that beta BIOS is that bad then I'll have to look into something else.
The memory was just way to expensive to replace at this time and the chip was only $80 and I could get the MOBO for around $45.
Thanks for your reply
