Hi guys, really need you experts' help on this one!

Just built the new system using the following after reading the overclocking article on the site:

G3258
R9 280 3GB
ASUS Z97-A
PSU 850W
ADATA 8GB RAM
Windows 8.1

I tried overclocking CPU using UEFI BIOS but no matter what I try CPUID & CoreTemp are showing my core speed to be at 800mhz (100 base clock * 8 multiplier). Even at factory default settings, the core speed is stuck at 800mhz

CPUID does show the max available multiplier to be equal to what I designated (8 - 42) but speed never changes whether it be while testing Prime95 or playing games.

Things I have checked:

Updating BIOS version - still at 800mhz
Changing to default factory setting (no OC) - still at 800mhz
Enabling/disabling Intel SpeedStep - still at 800mhz
Enabling/disabling C-State - still at 800mhz
Checking chip damage/bent (no apparent damage) - still at 800mhz
Using AI Suite 3 to OC - Target speed changes to what I set it to but actual speed still at 800mhz

As to CPU voltage I left it at Adaptive setting with .05 offset.

I really don't know what else I can do at this point. I had searched the net and the following seems to be one thing I can't really check since it's a different CPU/Mobo:

OH and one more thing, when I play games, core speed is still stuck at 800mhz but load is at 100%. Good thing I have 6 fans blowing...



Thanks in advance!

Just pulled the report from HIWINFO:



CPU Turbo clock is the clock speed that I designated the CPU to overclock to.

I have no clue why the multipliers are locked (or at least that what I think is happening)...

Mobo is broken? CPU is broken?

Any pointers are appreciated!!!

I'm having same problem! Got my multiplier set at 42Mhz and CPU voltage set at 1.200. Clock speed was at 4125mhz, but now its at 800 and I dont have a clue why. Kind of pondering on if its a PSU problem, but I won't know till new PSU gets delivered.
I'll keep updated if I figure this out...

Have you tried to reset your CMOS?? If not, turn your pc off, pull the power cord off it then hit the power button to purge what power is left in system. Then pull the CMOS battery out of the motherboard and let sit for a few minutes. Then replace the battery, plug power back in and boot your machine up. You will have to reset the time on the BIOS, but it should reset all your BIO settings back to default...
