Please, could I get some help

post #1 of 23
Thread Starter 
I cannot get this thing to go past FSB of 220 which lets it run at 2419.8mhz. I am only messing with the front side bus numbers as the processor is locked at 11. What am I doing wrong? Could someone please help me?

you might need to bump up vcore a little. also it has a via chipset so typically they don't oc as well.

First increase vcore. Then loosen up memory timings, or put it on a divider.

Thank you all so much for the help. You need to be a little more specific for me. Could you possibly put it in laymans terms??

Many reviewers found it difficult to raise the FSB beyond 220Mhz no matter what they tried. This was down to the fact that Asus didn't implement an option to lock the PCI/AGP bus's on their original A8V Deluxe, but their later Revision 2.0 board (which you have) does.

"The usefulness of 300MHz driven clock is called into question by the hit-and-miss PCI/AGP clock implementation. We found it difficult to raise the clock much above 220MHz."

Speaking of overclocking, we were not able to get the board stable at even a 215 MHz FSB, let alone anywhere near the 300 MHz maximum allowed by the BIOS. We believe that this dismal overclocking comes from the fact that ASUS did not implement an AGP/PCI/SATA FSB lock, independent of the CPU FSB, on the AV8.

Given the information you've provided so far it sounds to me that you simply haven't locked the PCI/AGP bus to 33/66Mhz. This should be done before you start raiseing your FSB and voltages and should be possible on your Revision 2.0 board.

I also suggest that you take a look through the A8V Deluxe user manual to familurise yourself with the BIOS a little more.

Thank you. It's all in knowing what your doing!!

Now that did the trick. It had to do a few configuration and then started right up at 225/1.375. What other information would you need? How far do you think I can go??

Now its simple case of raiseing your FSB until you hit instability, at that point you need to raise CPU vCore. Though keep in mind your AMD's HT link when raiseing FSB as this will increase in tandem with FSB.

As an example, when you're at the default 200FSB your HT link will be 1000Mhz (200FSB x5 HT link = 1000Mhz). You don't want to stress your HT link too much and I find that it's always a good idea to keep this as close to 1000Mhz as possible. With your HT multiplier lowered to x4 you will be able to raise FSB up to 250 without haveing to worry about straining the HT link.

Bear in mind that when it comes to raiseing CPU vCore, your temperatures will start to rise so be sure not to raise your vCore too far for your cooling to handle. Simply use monitoring software such as SpeedFan, Motherboard Monitor, CoreTemp, or Thermal Analysis Tool, to keep an eye on your temperatures.

I am assuming that the HT link is the HT Frequency [1000] that is what allows the selection of HyperTransport from the CPU to the AGP. Configurations are 200,400,600,800,[1000] which is the default. Is that correct?
It is presently set at 1000 and CPUZ shows the HT number as 1124.6 with the processor running at 225mhz.
