Hi i recently updated my bios after window 7 setup and i noticed that none of my old settings i used worked when i was on window xp. Any setting i change in the bios seem to just lock the cpu up resulting in cmos reset every time. I tried everything from simple CPU multi increase and even AMD overdrive. Much help appreciated thx!

Changes from old setup:
Replaced all stock case fans with arctic cooling 120 mm pwm fans rated at .13a I have 5 of these fans in my case i have 4 of these fans daisy chained in sets of 2 occupying in 2 fan headers and 1 using it own fan header.
Reseated, reapplied the paste with arctic mx 2 on NB and SB to reduce temps.
Flashed bios to 4/21

7 and xp tax hardware differently, so you may need to use different settings (slightly higher voltages) in order to get them stable. I don't know what else to tell you since you cleared CMOS. Maybe downgrade back to the old bios?

edit: I believe that new bios is targeted for Phenom II users for unlocking cores, so maybe when you enable ACC it is doing something funky to the chip it shouldn't be doing.

Really hm ya i didn't enable acc and it still acting up i even tried manually setting my ram timings to stock and i get locked out. Would downgrading be the same process as upgrading? I was on bios version for phenom 2 support wonder what version that was.

Well i just found out what was causing comp to lock up it when i enable pwm in bios. Would the current cause of the stock settings under pwm be the cause?

CPU VID: 1.280
Dram volt: 1.950V
SB PLL 1.2v Voltage: 1.2v
NB core: 1.250v
NB PCIE:1.120v
NB HT Volt:1.270V
