fauLty 4th core after UNLOCKED

[kamotekid]

Has anyone encountered a faulty core after UNLOCKED?

results via CPU-Z

core 0: 804.09MHz
core 1: 804.09MHz
core 2: 804.09MHz
core 3: 804.09MHz

multiplier is 4

-Vcore is 1.12

-those were the results when i ran prime95, CPU-Z and HW monitor

What processor are you talking?

generally, if you buy a chip thhat can be unlocked, theree will not be any guarantee that it works when unlocked. Some products will have a sub-standard core that is disabled, while others will be fully working die that is disabled to fillorders for the lesser chip.

Without knowing what processor you are talking about, there is little else that can be added.

Thanks for the quick response sir. I am using Athlon II X3 455 @ 3.3 GHz then i got it UNLOCKED to Phenom II X4 B55. please help me sir... i heard a lot of good stuff regarding this forum so i search for this. thanks!

just a gist of what's happening when UNLOCKED:

The problem started when i unlocked the 4th core (which is AMD Phenom II x4 B55 processor). When i loaded the desktop, ran stability test for 2-4 hours, looks great and no errors and warnings but what i have noticed was the "core speed and multiplier" don't change at all even in FULL LOAD (800MHz and "x4" respectively). so i checked my settings in the BIOS, went to "AI tweaker" checked CPU and NB Voltage which is currently @ "offset" @ 1.475 then went to "Power Tab" and look for HW configuration and noticed that "Vcore" is 1.116v ONLY. i tried to change it however, i gave me 2 options only "either IGNORED or the VALUE ITSELF which is 1.116v. so i updated the BIOS from the ASUS site (dated: 03/30/2012-Version 1202) went to the desktop and tried it again..same result...won't pass the 800MHz core speed @ full and the Vcore is still the same @ 1.12v. I tried disabling C n Q and Ce1 under "Advanced Tab" then CPU configuration and saved it. Went to the desktop again and still the Vcore hasn't changed but CPU voltage is still the same. What I'm confused about is that the core speed doesn't go more than 800MHz and stays that way. I am expecting it to spike at around 3300MHZ @ full @ sometime but nothing has change at all.

There is no help for you - just lock the core which you have unlocked.

I unlocked about 20 - 30 different Athlon II and Phenom II processors, and never had a problem that you're experiencing. Some processors had faulty cores, that usually caused the system not to post, or not to boot into Windows. It seems that you already did almost everything to fix it (upgraded BIOS, disabled CnQ, raised voltage, etc). You can try to disable
C1E, if you haven't done so. Also, see if you have a Hardware Thermal Control feature in your BIOS, and try to disable it. Be very careful with this feature. The Hardware Thermal Control automatically lowers processor frequency when it overheats, i.e. when internal sensors indicate core temperature above certain threshold. It could be that the core has faulty sensor, or that the core overheats (due to being faulty).

i haven't tried to change the Vcore in the BIOS because it's not letting me do it. do i have to manually change the multiplier to 16.5 because as of the moment it is AUTO and not sure if possible since this is not a black edition cpu

here are my specs:

mobo: Asus M5A88-v EVO
cpu: Athlon II X3 455 @ 3.3GHz
cooler: CooLer Master Hyper 212 evo
psu: CooLer Master Extreme Power Plus 500W
RAM: Kingston Hyper X 8GB (2x4GB) @ 1333MHz
VC: ATI Radeon 4670 512MB (128bit)

hope that helps..many thanks sir for giving me a very slim chance of having this working as X4.
