Athlon II X2 new die or what? wonder which part they improve.. look at benchmark, it just a little bit better than previous athlon at same clock speed

@kunta
nk test Deepcool ka?
need to OC NB in order to get more BUS speed or multiplier?

kuntawakaw u did this test using ur TA790GX mobo ker??

I like to use rivatuner or ATI tools..

this is wat i mean..

Phenom OC Database
click at the spoiler..see my name..n see the nb clock there..

NB freq more then 5K
got... coolice got that board IINM...

it affect on balance.. left right should same range..
if lesser would bottleneck each other..

Whenever one is talking about the North Bridge (NB) of a Phenom II, it is safe to assume that they are talking about the CPU-NB. The CPU-NB is a section of the CPU that controls the L3, Memory Controller and the Hyper-Transport (HTT).

What i can feel is..My extracting,scanning,loading,converting become faster by around 2~10% since i overclocked the NB Frequency.
Gah..Bro digswell want quit?no way lah

Ok now i understand i think

i still dun understand..
NB=CPU-NB??
or they are different thing?

Remember, you're talking about the on-die NB controller, not the motherboard's NB controller...AMD systems have had the memory controller on-die for quite some time, and it's not to be confused with the 'other' NB

U forgot Baby

In my case when i play with the ACC on my Phenom II X3 it doesn't do anything, in fact it made my rig unbootable.. It will stuck at post

same goes when we play with the ram timing..

IINM SB700 chip just enable/disable the ACC thingy right?
on SB750 directly give certain value to control the 6 pins on the cpu...
what it do.. yet to be revealed..

@cloudwan..
try negative value..sometimes it works backward..

wat is IMC actually?
internal memory control?

ccc?? newbie here

da rivatuner still not detecting

last time this will be separate chip on mobo..
but since amd integrate it in the cpu for some reason..

earlier phenom use the same voltage that supply for the cpu due to mobo limitation..
the voltage controller should be separated as well..

guess what - control it with ACC..

*plz note some maybe not a facts but we try to figure it out and spot better explanation later..

AMD says that the settings tweak doesn't impact performance and doesn't change thermals or voltages, it simply can allow a Phenom processor to clock higher when overclocking.

In circuit design

In circuit designs, clock skew (sometimes timing skew) is a phenomenon in synchronous circuits in which the clock signal (sent from the clock circuit) arrives at different components at different times. This can be caused by many different things, such as wire-interconnect length, temperature variations, variation in intermediate devices, capacitive coupling, material imperfections, and differences in input capacitance on the clock inputs of devices using the clock. As the clock rate of a circuit increases, timing becomes more critical and less variation can be tolerated if the circuit is to function properly.

There are two types of clock skew: negative skew and positive skew. Positive skew occurs when the clock reaches the receiving register later than it reaches the register sending data to the receiving register. Negative skew is the opposite: the receiving register gets the clock earlier than the sending register.

last time only one option - u raise the cpu voltage.. thus the imc get the same..
that's why more or less i think.. ACC tweaking that part to balance the things..
whether u want OC for performance or loose certain parts for VALUE setup..

in other words..better OC CPU-NB not so high..coz the temp compile with CPU+HTT+CPU-NB..things getting fun..

reach 6ghz use LN2..lol..
wat i mean is..OC CPU-NB..temp increase also..so its quite hard to achieve the better one(limit of air cooling )..

PII hv include acc in the proc..
while PI not..
so no use of change it in bios(sometime it might be unable to load)..

so, i think i will use CPU-NB rite now..see if can OC more..

bro coolice!!
enlighten us with ACC n CPU-NB thingy pls..

SB700 got ACC but cannot unlock to quad core right?

tq...will try ati 1....

im using galaxy 9800gt
