well i put together my rig..720/ ud4p mobo with f2B bios (enables ACC) and guess im just not so fortunate to unlock the 4th core. had tried ACC auto and all cores, no post and yea..just wanted to share. but putting that aside, imma find sometime this wkend hopefully and OC this damn chip. so far..i've had it on 3.3 on stock volts, with 15mins on orthos blend..so lets just hope i can even hit 3.6+ if not..damn..ill be shtting my pants. =/

You shouldn't have a problem reaching 3.6+ with that cpu / mobo combo.
Sorry to hear you were not one of the lucky ones able to unlock the 4th core on your 720.
If enabled, it may have made you grown grey hair with it's unstability or lack of consistancy.

These new Phenom II are amazing aren't they? 3.4GHz-3.5GHz on 1.35v(stock for me) coming from ~3.3 @ 1.5v

go into ACC and by default the options under "all core" should be @ -2%? select "all cores" set it to 0, then set ACC back to AUTO. and reboot. and see if it'll pick it up

good luck.

i just booted into windows @ 3.56 as we speak..see if i can stress it..LOL

the 4th core is not stable..regarldess of what volts or frequency...sigh*

yeah found this out with mine. i got it to boot and allow me to get cpuz open, but was never stable enough to validate so i just said forget it i'm happy with 3.8ghz anyway

currently stressing @ 3.8 - 1.5v, how safe is that to have it run 1.5 if stable for 24/7??

**temps are 35C load - easytuner reader.. coretemp reports 28c, seems like gigabyte's easytune is pretty accurate if it is hmm..

prime 95 stress test. if it's under 50, it's very fine. push it more

the problem is..running @ 1.5..wouldnt that hurt the chip period? even if temps are within limits..and i tend to like orthos more =/ even tho i always have to assign separate cores..but..idk.. i just like orthos!

hmm 1.5? not at all. but you're near crossing the line. don't worry amd chips are like tanks and can handle lotsa voltage for as long as it has good cooling.

but i think 1.45 is enough to go 3.8. then 1.5 should get you 4.0.

nah 1.45 was only good for 3.65-almost 7

gerikoh

· #18 · Mar 20, 2009

i guess. but you can still push it further to 1.55. you've got a good hsf anyway

The phenom IIs tend to overvolt when under load by 0.0200-0.0500v. I'd recommend not going too far above 1.5000v.

7 1/2 hours stable @ 3.7 - 1.475. going for [email protected] same volts now...see what happens

did i mention RAM is basically running 1:1 atm and is overclocked beyond 1066 now..har har..

and i just have a general question since my last rig was a nforce board in the 939 era, how does this new NB frequency and HT link work now? the board i have..supposedly supports full 2.6ghz HTT right? but the 720's max HTT is 2Ghz. so what does the NB frequency have to do with it? or is it the NB max frequency is 2.6Ghz on this board? this is where im lost in the
