X6 @ 3.7 Ghz or X4 @ 4-4.2 Ghz ?

Hey guys so I got my new phenom a week or so ago. I unlocked it to 6 cores and over clocked to 3.7Ghz, it is prime/OCCT/IBT/LINX stable for 24+ and has always ran perfect and never crashed. But for some odd reason every once in a while the system will hang loading windows on a cold boot, when i restart UCC is disabled and CPU is set back to 960T. All other OC/Power/Boot settings in the BIOS are the exact same.

Having the X6 is pretty cool (especially for $99.99!) but in all honesty I don't really use all 6 cores very much and having to keep screwing with UCC is getting kind of annoying. I have since knocked her back to 4X and have a very stable 4Ghz OC (I'm sure I could hit 4.2 if I tried more).

1st question, any ideas why UCC keeps shutting off ?

2nd question, Is all this effort for the X6 even worth it vs. the 4-4.2 Ghz X4 ?
 
1) Could not be fully stable for BIOS, a little more voltage maybe can help or disable on core to get an X5 and test again.
2) You should test both, performance with X4 and performance with X6 and select the best one for you. I don't think that you see a big difference, but the last word is yours.

Completely depends on what you're generally running. Some apps will do better with x6 at lower speeds being able to fully use all 6 cores, while some are able to use multiple cores they limit at 4 and the higher speeds will be a benefit.

I have the same processor and it runs like a champ. I typically run it at x6 when I can just for the additional cores in case I need something. I don't mind waiting an extra second or two for something to finish.

What's the voltage on the x6 OC? Also, what are you seeing your temps at fully loaded?

X6 vcore is 1.35 idle 1.37-1.39 Load (idk why it fluctuates I have everything disabled) temps are about 25C (estimated) and mid 50's sometimes low 60's load. (cant get true core reading due to temp sensor non function with unlock, so i just -10c from socket temp)

X4 vcore is 1.38 idle 1.40 load. 20C idle 29-30c max after 24 hours of prime small FFT

It definitely seems that having the chip unlocked creates alot more heat with less voltage, idk i checked out the TDP on the 6X thubans and it doesn't seems too far off but the temps are just way higher (even with CM-212 push pull and AS-5)

Room ambient temp 68C (my cores idle at room temp with a 1Ghz OC << bragging a lil lol)

Idk let me know what you think, thanks for the help.

Yeah Idk man, most unstable OC's i have run into fine in the BIOS and fail to run/boot windows. This one runs flawlessly in windows(24+ stable), only issue is UCC keeps shutting off. I'm lost man lol.

I'm a true tech nerd at heart, I love wringing every last drop of performance out of my rig. It will bug the hell out of my having the possibility of X6 and not at-least trying to make it happen lol. The X4 probably does the job just fine, it's the itch for more that gets me lol.

Thanks, I find that I get more than sufficient performance with the X4 in most cases. If I need the X6 I can enable it as it works perfect once booted. Idk still really odd the way UCC act's, anyone ever heard of a bad BIOS chip/software/UCC programming causing issues like this ?

Hi!

I think i had the same problem when overclocking this CPU with a Crosshair Formula V.
On prime it was stable but on a cold boot it hanged and used to lock those 2 extra cores again...

I solved my problem by overclocking through increasing the CPU Bus instead of increasing the multiplier (that's kinda odd because this CPU is a black edition/unlocked)

Later on, asus release a BIOS update (1301) and this issue no longer occurs. Now the overclock by multiplier works just fine.


Hope this helps...someone...
