The "U" at the AXDA2200D[B]B[/B]V3C means that my default VCore voltage is 1.60v right? But my CPU runs at 1.52v at the Auto Vcore voltage and its running fine and stable. Another thing, is my Tbred B unlocked by default? Cause i tried to connect the last L3 bridge to unlock it, but no different at all. And also tried to change the multiplier without modifying anything at the CPU also cant. Will not POST if i change the multiplier other than Auto.

"The "U" at the AXDA2200D[B]B[/B]V3C means that my default VCore voltage is 1.60v right?" I don't see a "U" in that model number at all...lol Operating Voltages: L = 1.50V U = 1.60V K = 1.65V M = 1.75V "my CPU runs at 1.52v at the Auto Vcore voltage" Could be the voltage isn't being reported correctly, could be the board is undervolting. If the BIOS allows it, try manually setting the vcore to 1.60v & see if it's still reported as 1.52v "i tried to connect the last L3 bridge to unlock it, but no different at all. And also tried to change the multiplier without modifying anything at the CPU also cant. Will not POST if i change the multiplier other than Auto." The 2200+ is a poor CPU choice due to the high default multi (13.5x) & your's is obviously locked. To unlock it, you have to connect all the L1 bridges & the L3 bridge http://www.madshrimps.be/?action=gethowto&howtoID=16 This space for rent

ok sorry for my technical typing error...lolz its AXDA2200DUV3C :) i try to set the VCore voltage to 1.60v manually and it really report the voltage as 1.60, but when at Auto it reported as 1.52. Do you think should i set it manually to 1.60v or just let it be at Auto? By the way, i've already seen that site unlocking method and it only said i need to connect the last L3 bridge only, the L1 bridge is already connected by default. I doubt that maybe is because mine one is a Tbred B core so it is different. MSI KT3 Ultra 2MS-6380E Athlon XP 2200+ Stock DDR512 PC2700 2-2-2-6 Asus ATi Radeon 9200SE 128MB Windows XP SP2

If its unlocked, then overclock it to the max and set the vcore to max... Otherwise, its auto is 100% stable, then leave it as auto. Lower voltage implies cooler temperature and less power consumption.

The problem now is why cant it be unlock? Anybody with Tbred B can unlock here? MSI KT3 Ultra 2MS-6380E Athlon XP 2200+ Stock DDR512 PC2700 2-2-2-6 Asus ATi Radeon 9200SE 128MB Windows XP SP2

mine can't. i could just oc the mem freq. if you still can't oc through bios, use CPU FSB. Athlon 64 2800+ @ 2.63 Ghz on Stock Cooling Timings:2-3-2-5 V-Gen 512MB pc3200 DFI Lanparty UT NF3 Abit R9550 VGuru XTurbo 525Mhz/300Mhz

Fel, i think you do not understand what i am saying here. What i mean is to unlock the multiplier for the CPU, nothing to concern about cant overclock in BIOS with changing the FSB. I can overclock with changing the FSB, but if want a higher FSB without going more than the CPU limit, the multiplier must be unlock so that i can get higher FSB frequency without breaking the limit of the CPU frequency.
