I have a confirmation of fedex delivery with monarch and will be getting in my 3200+ later this week.

I purchased along with it the Asus 939 A8V. I also have a X800XT PE and PC3200 Corsair XMS 1GB

I have been running intel for about 2 years now and I am wanting to overclock this configuration.

I will post all of my trials on this site with info on what worked.

The chip is a winchester and it is 200x10multiplier=2.00ghz

I am wanting to get it to 2.40 ghz is this as simple as upping the fsb to 240?

Should I get new ram?

Timings on ram (TWINX1024-3200LLPT)

2-3-2-6 1T

I will be running the CNPS7000A-Cu HSF on this chip.

Please give me tips and advice (I am the guinea pig)

It's as simple as raising the "FSB" (really HTT as there is no FSB with the on die memory controller), assuming the CPU will make it there. You may need to lower the HT multiplier as well.

Start with the memory set to 166 (5:6), which will run the mem at 200 MHz, rated speed. Later you can check if your RAM can run 1:1. You may want to take smaller steps with the CPU before just going to 2400. Nobody knows how the 90nm CPUs will overclock. There has been surprisingly little info anywhere on the web on how the 90nm CPUs will run.

To me the steps are:
1) set RAM to 166 / 5:6 ratio
2) move CPU up to 240 HTT in small steps
3) set RAM to 200 / 1:1 ratio and set RAM voltage to your max comfortable level
4) Set HTT back to 205, then inch up to determine where RAM is capable at various latencies.

Pretty much the same procedure as overclocking a P4. with the exception that you have the option of finding the RAM capability first if you want because you can lower the multiplier on the A64, while you can't change it at all with the P4.

Is the A8v similar to k8V? Because in the K8v you cannot control the multiplier manually. Also, the pci/agp is not locked so incrementing little by little may be bad.

btw Glavinsolo, you may want to post this in CPU/Processors and Overclocking?

A8V Rev. 2.0 has locked PCI/AGP and has better overclocking options in BIOS. I'm not sure why but ASUS chose the A8V as their overclocking board and not the K8V.

I was assuming he would be getting a rev 2.0 board. I think that's all they're selling right now at Monarch.
