Gulftown easily to present this beheavor.
try compare to any previous BIOS.
i verified and compare wth F5 & F6

Gulftown(Q3FE)
X58A-UD7

1.In bios only change QPI/VTT value
2.OC to specific BCLK (such 175MHz). boot success
then change QPI/VTT again

F5,F6 shutdown and restart even only change QPI/VTT to 1.2v (
tested 1.2,1.3,1.4,1.5,1.6v)

F6 Test 1 BIOS won't do shutdown & restart.

1. help you more easy to oc gulftown even with general air cooling system
reduce shutdown & restart chance helps you to build a strong general oc system.

2. with extreme oc, if your chip coldboot -160, coldbug -140, when you
running -160 testing and clock instable( such blue screen or freezed screen)
will shutdown & restart due to QPI/VTT BIOS changing. and fai to bootl, cuz cpu
coldboot at -140, and you try to reboot at -160 with previous BIOSes.
with this new beta BIOS could let you to avoid this situation, so this BIOS
helps you alot when do extreme oc.

This BIOS fixed
1. QPI/VTT value change with Gulftwon CPU
2. Gulftown IMC oc fail, need to remove power cord, new BIOS fixed.
3. Gufltown OC fail, F1~BF fast looping, need to remove power cord, fixed.
