Well, 4770 Is Cheap Compare n Use Less Power Compare To 4850.In Most Benchmark,4850 is Doing Better.If U Intend To Oc 4770,Then It Will Be A Good Bargain.

deym..i cant OC to 3.6..b4 this can..
adui..after turning on ACC trus jadi camni..
then disable the prob still got..

yeah..but not in my list...
dun hv money to upgrade..9800GT is enuf for me..

Try Different Setting.Don't Be Bothered By That ACC Thing.

Maybe U Can Upgrade Ur RAM.Use A Performance RAM 

lol..b4 this i reach 3.63 with prime test without any prob..
the i default the clock back n try ACC..then it cant even reach 3.6..
after i disable ACC it cant reach 3.6 also..

reset CMOS ka?

1st attempt
Prime Stable - 1 hour

Phenom II 940BE
CPU stepping : CACVC AC 0852GPMW
Revision : RB-C2
max CPU clock speed : 3637.0MHz (202.1 * 18)
CPU voltage : 1.438V
Northbridge clock : 1818.1 Mhz @ default
motherboard used : ASUS M4A78-E
type of cooling : Sunbeam CCF

If you OC and a core fails on prime then add 1% on the core that failed and so on. So if core 2 failed add 1% acc on that core. It might need more if it keeps failing Prime. Somthing like that. And I think "auto" is 1-5% on each core.

There is no impact on performance, no change of voltages or frequencies, it just allows for more and higher overclocking. Anandtech reports that the new BIOS of coming motherboards with the SB750 southbridge has a much wider range of settings for the Advanced Clock Calibration (ACC). In the past this function could be set in increments of 1 between -2 up to 0. With the board they've used they could set ACC to anything between -12 to +12. Negative values unlocks lower power operations while higher values unlocks better overclocking.

i tot acc will help us to gain more..
here i quote something.
u set it at what? im still in a learning process of understanding things. discussion is the best i guess..

ACC meant to be for phenom I..but not phenom II..
thats wat i read at the website..

n yes ACC help phenom I to OC stable..

no all chips bend down to acc. but i had gud experience usin it w/ my 9550, 9750, x2 7750 & x3 720. +2%~+4% are quite common to some aod users, they work pretty well. 

u nver try it to the max? i still cant understand how the tech works.. it doesnt alter the voltage right? so how come they say lower acc setting will saves energy and higher acc meant for oc.. what they use to make the oc stable? anyone able to guess it? amd not reveal their tech to public.. but im curious to know

AMD never explained how ACC works..
so i dunno..yes i read bout negative value help increase efficiency n positive value help in OC..

i never use it LOL. mayb thats why my clock is lower then other ppl.

its meant for k10....
but... a k0 proc cant use.. joke2

@ventrilocks
yep.amd nver reveal it. but i hope someone here read somewhere about how it works. mebbe got freak and pro out there able to figure how it works.. antonio had explain it last time but lazy to scroll back

Exactly what it does hasn't been revealed, but it somehow seems to loosen the strains a bit and allow the cores to be pushed further in either direction. It should be emphasized that this is a Phenom-exclusive feature. You will not gain anything with your Athlon series processors. We should also mention that AMD will use this feature with its coming 45nm processors, which means that the prior reports of decent overclocking with the Deneb core, may be understated.

hello,
i've got a Phenom 9150e...(well, u guys know where i got it)

i wana know if i oc this proc, will the performance better or just the same(or even worse?) compared to my current proc which is 6000+... the performance i mean is in terms of gaming...

most games utilize on 2 core..
but games like gta4 uses quad core..
so wat im gonna say to u..OC ur proc to reach the recomended requirement of the games..
of course OC will give more performance..but if it only stable la..

gaming i suggest u for a higher clock one.that will be 6000+
multitask,9150 will do better... theorically higher clock will perform better..since gaming not using the 4core to the fullest.
i donno about the real world.. i guess it still the same as what i mention above
