So, anybody knows whether it affects upgrading from single-core AM2 to dual-core AM2?

Theorectically, it should right?

There's definitely a difference when you upgrade to dual-core from single-core.

Some of the difference that I've noticed are:
1) Windows boot faster, and you can start doing things earlier instead of waiting for windows to boot all the drivers and applications.
2) Games run smoother, especially if you're running a lot of background apps (esp. P2P)
--- the fps in games is the same but it feels smoother, no more occasional lag due to usage of CPU power by other apps
3) Alt+Tab to windows is noticeably faster (but only in 1-2 seconds)

I can feel the differences as I just upgraded from single-core 2200 Mhz to dual-core 2200Mhz. (with the single-core overclocked to 2442 Mhz!!)

You know what? I think this thread should be kept permanent. And a good place to put is Essential Reviews and Guides

Very nice thread indeed.

but why after i upgraded from single to dual-core, my C&Q can't work anymore ?

Theoretically, Cool N Quiet can be enabled when we are overclocked.

Practically I've tested, and no problem found in 1+ years.
I have 0 lagginess effect when CnQ enabled even during gaming.

almost all X2 user here...
where's Opty Dual Core user

im thinking to upgrade my Opty from 144 to 165@170
anybody want to let go their Opty??

cannot tahan using single core doing photoshop + 3DsMax + multitab Firefox
plus im a heavy gamer myself~

Chow.

enable it in BIOS, then reinstall ur power management software from AMD website.

Wait for Barcelona

oOOoo.. didnt know theres 939s X2 thread here... heh

Btw, i read some tweak and forums abt installation of AMD X2s.

I read that (hardware forums and website) the "MS duo-core hotfix" its meant for laptops/notebooks (power issues).

So, basically the juz need to install "AMD64 X2 drivers" and "AMD dualcores optimiser" only, no need "MS hotfix".

Correct me if im wrong...

Cheers

Hey friends,

How bout rig that's running on Vista? Also need to apply those steps? I agree, this thread should be kept permenant.

Well, the Microsoft hotfix last time was for the dual core AMD Opterons IIRC. I do remember last time when i install the driver for my AMD Opteron 165 where AMD themselves claiming that their Dual Core Optimizer is not for the Opteron series. Only for the X2 series. Therefore, this is where the MS Hotfix for dual core comes in..Well, thats what i learn from AMD forum last time..

I don't think it is only for mobile CPUs. If you read the link on MS hotfix, they state that:
- "Without these updates, computers that are equipped with these power management-capable, mobile, dual-core processors may experience decreased performance or unexpected behavior". I do agree that the grammar is a bit confusing. Does MS mean ONLY computers with ACPI + mobile + dual-core or computers with EITHER ACPI + mobile or ACPI + dual-core.....

- "This hotfix also addresses the following issues on computers that have multiple processors that support processor performance states".



Vista is not affected. Windows XP needs to hotfix as it was not originally designed for multi-core CPUs that supports ACPI performance states..... Quote from MS:

"Windows XP SP2 is required on computers that have multiple CPUs that support ACPI processor performance states. This requirement includes computers that support the following items:
. Multiple physical sockets
. Multiple-core designs
. Multiple logical threads, such as Intel hyper-threading technology
Because Windows XP was not originally designed to support performance states on multiprocessor configurations, changes are required to correctly realize this support on multiprocessor systems. Windows XP Service Pack 2 includes the required changes to the kernel power manager. These changes make sure that Windows XP correctly functions on multiprocessor systems with processor performance states. "

ah sou....so don't need to apply anything on vista is it? not even the dual core optimizer?

I think not as I have not come across any websites that mention this.

So, unanswered question : Does it affect AM2?

i think
AM2 is the suckest CPU but the motherboards rock
ahahaha
the only recommended AM2 cpu is the Santa Ana and the FX-62
the X2 just a downer
ahaha

btw, i got this q la
why my fx-60 rig in my sig got only 3900+ in 3dmark 06 but in games, they run really smooth in full settings like spiderman3, company of heroes, FEAR, Q4 sume
darn

My non-OC rig only got 3416 la.... You only need at minimum of 25 fps for any games to be smooth (although gamers feel it is only smooth at >60 fps). So, if you're getting like 40 fps, then it is as smooth as a rig with a 3dmark06 score of 10k running at 100 fps!

the problem is when i redownload the new driver version of power management software from amd website and install, the new driver still keeps detecting my old type of driver....

BTW my C&Q is enable to on at bios liao...

Some games really depend heavily on GC rather than CPU...

Why not try Rightmark CPU clock? It can do what C&Q does.

Since I'm overclocking in windows, my bios C&Q is disabled. However, because I'm using RM CPU clock, in windows, the C&Q function is running. I will disable it when I'm overclocking, otherwise, in normal times, it is on.....

Can i ask some question here..

Does an OEM proc of 3800 sc939 must put a thermaltake if i'm changing a proc..

Hope didn't need to put since running out of cash..

If need then hav to borrow from brthr..

If you're not overclocking, then the stock heatsink is adequate.

If you want to overclock, then it is better to buy a third-party heatsink.

Note : Thermaltake is only one of the many choices you can find.....
