Phenom2 X3 720 BE @ 4 cores @ 100% OC ;)

[PcCI2iminal]

for some unknow reason that Phenom hates voltage and anything higher than 1,87v is worse than 1,85v
4 cores @ 4800Mhz for 3d06 is possible and the cpu score is more than 7500 but i can not finish the Deep Freeze ,i got a black screen at the end

MB - Biostar TA790GX3 A2+
CPU - AMD Phenom2 X3 720 BE @ 4 cores (ACC @ auto)
Ram - Team 1066
VGA - Galaxy GTX285
Pot - F1-EE
Cooling - LN2 (full pot)
Core FID - x20~x23(4 cores) or x25(3 cores)
Core VID - 1.35v
NB FID - 1600MHz~2400MHz
HT link - 1000MHz~1200MHz
Vcore - +0.5v~+0.52v
Ram - 2.25v
Chipset - 1.2v
HT voltage - 1.2v
Graphics and HD audio - off

having the same problem I was having, cpu-z 1.50 is rejecting like crazy

weird with the 06 issues? I think i benched 06 around 4680 on DI

yes

try to send a mail to Franck and send the saved file to him

Ive tried 4700Mhz and 4650Mhz but it was the same -> a black screen at end and i was running out of LN2 so i aborted

do you know the stepping off the cpu?

Nice!!

Yes, I heard on local forum yesterday, we can active 4th core on phenom II X3..But we don't know what 4th is completely OK (stepping), and I think most of bad for OC. So your cpu-z at 5700+ is very impressive, but four core only stable under less than 5Ghz..

good job

Nice clocks PcCI2iminal
I love your pics (with F1ee)

PC what cards were you using?

The only place the cpu really gives me any issue is cpu test, If fail on nature, gpu ram, If fail on boat GPU core, If fail on deep freeze ? maybe system memory or gpu related......

I ran into a weird bug myself with ram clocks on crossfired 4850's 9.1 drivers and ram clocked at 1185....fails cpu test, higher and lower ram clocks fine.....

Great to see that some of the 4th cores of the 720's are actually usable,
AMD just keeps on getting better and better!

[EnJoY]

Nice stuff Junior!

[V2-V3]

Very impressive getting the 4th core to 5700MHz!

looks to be a very nice chip you have

Have you played with the ACC much?

seen any gains w/ + or - on the cores?

[N00B]

You Rule !

[Spectrobozo]

very impressive, you tested 3dm06 on aircooler with the 4 cores active?

[Borys]

OMG nice results. Keep on pushing :]

[PcCI2iminal]

thanks guys

its everything about luck ,a friend of mine got the same cpu and the 4th core is only good for 3200Mhz on air ,everything above it and the system will crash

The card is GTX285 with 181.22 with a safe clock range (750/1500MHz)

with trhee cores i can push a bit more

3600MHz(1.45v) ,3800MHz is possible but the X3@X4 needs tons of vcore :S

[okorop]

but I think it is the world frequency record is not it? very good job well done
