I recently purchased a pre-built PC without OS installed: 

 

CPU: AMD FX 6300 3.5 GHz, 14.0 MB Cache, Black Edition with heat sink fan

Motherboard: ASUS M5A 78L-M LX Plus (with ATI HD3000/ AMD 760G graphics)

RAM: 4GB DDR3

 

Initially I installed XP Pro 32-bit, as I had used on my old PC, whilst making up my mind 

whether to upgrade to Win 7 or Win 8. As I had been my previous practice with XP, I installed 

the proprietary drivers provided on the ASUS motherboard support DVD 

(AMD 760G/SB710 Chipset Support DVD Rev.V1016.02) namely:

 

AMD Chipset Driver

RealTek Audio Driver

AMD Graphics Driver

RealTek LAN Driver

ASUS EPU-4 Engine

 

Everything seemed to function well and the system ran quietly. After some deliberation, I decided to upgrade to

Windows 7 SP1 Home Premium 64-bit (OEM). I had read that Win 7

 is rather better (than XP used to be) in finding the right drivers.

 I did however run the MS Windows 7 Upgrade Advisor’ utility

 beforehand, which indicated that I would need to install two additional 

 items:

 

AMD CoolnQuiet Utility V21801 - the Win 7 upgrade advisor provided 

the web link to the required version.

 

RealTek PCIe GBE Controller - for which I located the Win7 version 

on the RealTek web support site

 

So, I installed Win7 letting it select it’s own drivers. 

Since the RealTek PCIe GBE controller driver was required for LAN

connection to the internet, I installed that, and at the same time the AMD 

Cool ‘n Quiet Utility. Then I let Win 7 do all of it’s auto-updates. However, as I was checking through the installed 

programs and I clicked on AMD Cool ‘n Quiet, it displayed the message 

that ‘Cool&Quiet is not supported by this CPU’, which I thought strange. 

Why did the Win7 upgrade advisor point to it if it wasn’t supported?  

 

I phoned the shop who built the PC. They said don’t worry about the 

Cool ‘n Quiet and just install and use the ASUS EPU-4 Engine utility

 as it serves the same purpose. I asked if I should change anything in BIOS, 

and they said, no, as the Cool ‘n Quiet would be Disabled by default in

 BIOS. So I simply uninstalled the Cool ‘n Quiet application.  

 

That said......

 

1. I ventured into BIOS, for the first time, and found Cool ‘n Quiet 

was in fact Enabled.

2. From what I have read, ASUS EPU-4 acts purely at the software 

level and so is not a real substitute for Cool ‘n Quiet which modulates

 the CPU directly.

3. Searching the web for more information I see many posts, typically

 on gaming forums, where someone is querying whether Cool ‘n Quiet 

should be enabled or disabled when over-clocking the FX-6300. 

 

Now, I am not a gamer....at all, and, frankly all of this over-clocking stuff

 is over my head. My main reason for choosing a 6-core AMD based-PC, wasbecause I do a lot of video editing, processing and encoding and the 

FX-6300 was recommended to me as a good mid-range multi-core processor 

for that type of ‘cpu-intensive’ work. 

 

So, whilst I am not particularly interested in pushing the FX-6300 to 

it’s limit, I can see the benefit of a functionality that automatically provides 

more CPU juice when needed. 

 

When I was running XP Pro (32-bit), the EPU-4 Engine utility appeared to 

be doing just that. Set to Auto, it appeared to switch from Max Power Saving 

Mode (when idle) to Performance Mode when required. I could hear the fan 

blowing a little harder, but otherwise it stayed fairly quiet. Now that I have 

installed Win 7 (64-bit), it still runs quietly when idling, but when Performance 

mode kicks in it is a lot noisier than before, with a kind of buzzy-hum that 

vibrates the casing. Of course, I’m a little concerned. 

 

I have also noticed, on several occasions, that the EPU-4 Engine status icon 

doesn’t appear in the system tray when I boot into windows and I have to 

manually open it from the Programs menu. Never had that problem when

 I was running XP Pro. 

 

The EPU-4 Engine version that I installed (EPU-4_V10201_Win7VistaWinXP3264

was the (only) one listed on the ASUS website for the M5A 78L-M LX Plus and 

Windows 7, so it surely can’t be a matter of compatibility. So, I don’t know -

 is it normal that the PC should sound noisier with Win 7 64-bit? Is it maybe the 

CPU heat sink fan worker harder? There is no other casing fan installed.

 

And I’m also still wondering about this Cool ‘n Quiet thing. 

 

Is Cool ‘n Quiet technology supported by the FX-6300 or not? 

If it is supported, why would the program say it is not on my PC?

Would replacing the existing “windows drivers” with the latest 

MB chipset drivers (for Win 7) from the ASUS website make any difference ?

And, if it is not supported, should I Disable the Cool ‘n Quiet 

setting in BIOS, or does it not make any difference. 

 

Thanks.  

 

P.S. Sorry about the inconsistent paragraph formatting. It came out that way when I pasted in my message.

Cool and Quiet operation is built into the CPU by design. The Asus BIOS allows it to work with Win7 or newer O/Ss.

You should also be able to adjust the percent of CPU fan speed in the BIOS. It's possible that C&Q is using a slightly little higher fan speed than the Asus EPU-4 engine utility did but you should be able to lower this if you desire.

C&Q and the other power level and frequency auto adjust features reduce heat, noise and power consumption under light to moderate loads. For CPU overclocking many people including the folks who published the original AMD Overdrive software, suggest disabling C&Q and the other power reduction settings to insure these do not interfear with overclocking the CPU higher than it is officially rated for.

If you're not overclocking then you can just leave these features enabled and enjoy the benefits of C&Q and the other designed in power reduction features.



-------------------------

Building a reliable PC involves more than just assembling the parts. You need to be able to configure all of the BIOS settings appropriately. This can be quite involved and frustrating as it can require a lot of trial and error with stress testing. It is however often the only means to get a 100% reliable PC.
