OverClocking Athlon II X3 455 @ 3.3GHz

ren_kamotekid · Jul 29, 2014

Hello All,

Hope all is well. I hope someone can help me overclock my Athlon II X3 455 processor as it got unlocked to Phenom II X4 B55. The problem is that the all cores:

core 0: 800MHz
core 1: 800MHz
core 2: 800MHz
core 3: 800MHz

*muLtipLier per CPU-Z is always set to 4

as i ran Prime95, core 0 - core 3 don't go pass 800MHz when on fuLL Load. TIA!

Does it work normal as a three core?

Gotta shut off all the power saving stuff. Like C1E and Cool and Quiet ect.

Gonna need more info about your rig. List all the specs and the PSU with that too!

ren_kamotekid · Jul 29, 2014

yes it does and i tried running stress test on it for 4-5 hours using Prime95. btw, i got an aftermarket cooler, Hyper 212evo

Look in the case at the stuff. usually makes and model #s are on the stickers.

So, if it works normal as a three core, and you unlock it and it doesn't work, what does that tell you?

Hint:
unlock failed.

There is no guaranty on unlocks. They were locked for a reason.

sorry but looks stable though when booted to windows. its just that i doesn't go up to more than 800MHz per core

That is good if you wish to only run 800Mhz on each core. However if you prefer speeds over 3.0Ghz; well that will have to be done with the correctly working 3 cores.

What motherboard are you using and does the installed bios support the X4 B55? This sounds exactly like a motherboard that cannot correctly identify a CPU and so reverts to a basic lower power configuration.

Please attach a pic of the "Motherboard" CPU-z tab. That will give us the info about the make and model of the board and the bios version.

just found this link:

Athlon II X3 455 is supported however, cannot see Phenom II X4 B55 (unLocked from originaL CPU)

I have looked a couple times and can't find the thread I'm looking for. But I did read that specifically with ASUS there were some bios versions that would unlock cores and they weren't useable but there were certain ones that worked. I will continue looking and don't remember if that board was one on the list or not.

ren_kamotekid · Jul 30, 2014

thanks! while i was checking for my mobo specs, i found this link:

http://www.asus.com/Motherboards/M5A88V_EVO/HelpDesk_Download/

wondering if I should flash my bios version from "1202" to "1801". so far, 1202 version is stable and this is not 100% resolution to this issue.

Johan45 · Jul 30, 2014

One thing that I did find is this with no resolution http://rog.asus.com/forum/showthrea...-evo-and-AMD-Athlon-II-X3-455-(3.3GHz)-as-CPU
Sound familiar?

ren_kamotekid · Jul 30, 2014

updating my specs as previous post is missing some component details.

OS: windows 7 64bit - Ultimate
HDD: Seagate Barracuda 250GB
ODD: LG with Lightscribe
CPU: currently running Athlon II X3 455 @ 3.3GHz (relocked from Phenom II X4 B55)
PSU: CoolerMaster 500W
CooLer: CM Hyper 212 EVO
Casing: Generic Casing with Left Side Panel Open
Motherboard: Asus M5A88V-evo

Here's another post http://www.tomshardware.com/forum/334920-28-unlocked-processor-running-800mhz-vcore
Sounds pretty common to a core that unlocks but won't function properly. You're probably out of luck.

ren_kamotekid · Jul 30, 2014

Thank you so much sir for your quick response on this. Maybe I would just leave it as it is and will study how to OC this tricore that I have. Thank you so much again! :attn:

Johan45 · Jul 30, 2014

That's probably for the best. I read some of those links and sounded like people had nothing but headaches.

Most games a apps won't benefit much from having a fourth core anyway.
