I know others will tell you to set it at 4x but at 5x with these settings, you still will be
below 1050Mhz on the HyperTransport Bus. Follow: 240x10=2400, using the 166
memory divider, you will be effectively dividing by 12 so 2400/12=200 and 200 x 5
= 1000Mhz.

Are you sure about that? I wasn't aware that the HT bus follows the memory bus. Gonna have to research this now.

EDIT: Zebo's A64 OC thread
Unless he's wrong also, he says LDT x HTT should be around 1000MHz. LDT is the HT multiplier 1x-5x and HTT is the system bus/FSB. BTW, ibex333 you should go peep into that thread if you want to push your CPU even more.

BTW, this $15 (shipped) HSF is all you need to keep even an overclocked CPU cool enough unless you have some specific needs (such as wanting to run silent, these aren't too noisy but not silent).

I take it thats the retail hsf for X2 3800 and up processors? Or is that from the Opteron series? How noisy? 3k rpm fan?

They are used in all dual core Opterons and higher end dual core A64. The fan supposedly does make noise at full bore, but just use BIOS to run it at a lower speed under a certain temperature. I did that on my wife's computer (Abit KN8 with Zalman 7700AlCu) and I think I set it somewhere like 40% power under 70ºC thereabouts. No need to manually undervolt the fan. Alternately there are Windows utilities (Speedfan?) to do the same thing if your BIOS hides the option.

Zap, you may be right. I checked out VIA's site and found that my ASUS A8V-E Deluxe with the K8T890 chipset can do something that the Nvidia chipsets cannot do:

"The VIA K8T890 integrates VIA?s Hyper8 technology supporting a 1GHz/16-bit HyperTransport processor-to-chipset link, that delivers up to 8GB/s of bandwidth to help ensure all AMD64 processor-based systems achieve their full performance potential. The VIA K8T890 chipset also utilizes asynchronous bus architecture, providing improved system optimization options to enable power users to squeeze the very most out of their systems."

From: http://www.via.com.tw/en/products/chipsets/k8-series/k8t890/

I think I can use the 1Ghz setting because the chipset has the asynchronous bus architecture, which allows my board to run the HyperTransport a bit faster than other chipsets. Also means I can set my HyperTransport independant of the FSB. Very cool for overclocking.

So, ibex333, set your HyperTransport to 4x.

OC that baby! The 3200's oc like mad. I run mine here (work) at 2.6. Just using some copper TT HSF. Also have same GFX card in the rig. I play anything I want. Not at the setting of my 7800GTX. But I can play things and have them look perfectly fine.

Copper = the metal used
TT = Thermaltake, a manufacturer
HSF = heatsink/fan

You may not necessarily need to replace your HSF because your CPU doesn't run very hot.
