This board has some AI and n.os features which I believe overclock as you go. Hence, it increases/decreases overclocks depending on the task?

Should I simply disable all these features and leave it on manual?

Im new to A64 overclocking and realise dividers are usefull here, unlike with Athlon XP systems.

Lets say I would like to run my opty 165 at 2.5ghz.
That would mean a HTT setting of 280. My ram will not run at that speed as it is BH-5 but the board only pushes up to 3v. So I reckon settling for 200mhz @ 2-2-2-? and using a divider should be possible.

Is there an equation that allows you to find the correct settings when inputting these parameters?


Thanks for any help. Advice on what TRas, bras, fras :) etc whatever... settings would be nice.
 
Right....

This has really turned into a farse.
System is acting up even at stock. USB devices work once in every three starts into XP. PS2 devices always work.

Regardless of what I set HTT in Bios CPUZ always displays stock speeds, except for ddr which it does display the settings I set it to in the bios.

Setting HTT between 200 and 210 with auto or 4x HT and the sytems loads into XP. Anything above, regardless of HT setting and it wont get to the XP splash screen.

My PSU was holding me back when used in the XP-M & NF7S setup with voltages dropping down to 11.3 when pumping high Vcores.
According to the Bios the 12v rail is around 11.6 which aint that bad?

Im kind of at a dead and here.
 
Strange. I'm having the exact same problem with my X2 3800 and Gigabyte board. I think it's either the PSU or the motherboard not regulating the power properly.

I tried a 20 to 24 pin adaptor for the PSU, and it made no difference.
 
What PSU is that? If it struggled on an XP-M you're reaching on an X64 system, especially if you're going for big clocks. You sure you got all the connectors on the mobo (I know there are 4 on the DFI, not sure about the ASUS)

(NB - I know DFI have now catagorically stated that their board DOES NOT support 20 Pin psu's - no matter what spec, or mod - hasn't stopped mine from working, but something to bear in mind!)
 
After doing some research I've found that the NForce4 drivers gives you an option of installing an SW-Ide driver. Apparently this one is causing problems for many users. No doubt I will format once home tonight and try without the SW-Ide driver.

As for the PSU, it is a ATX2.0 compliant PSU but it has 20 pins. The board has a 24 pin connector but that should not be a problem. I use the 20pin cable straight in the board, with no probs.

Im gonna flash the bios with v.1011 and see if it helps.

Will post back later.
 
What power output is your PSU?

Again from the DFI side of things, but a basic minimum from their spec is 480W with no clocking, and 55W if you're adding 'extra' stuff. We found through painful messing around that even with a 550W you can be dangerously close to the limit if you're really pushing the components - it really is a case of More is Less with the A64's! :rolleyes:

(As an example - TBird was playing with his rig, and with both GFX's in, whenever he switched on the monitor on the second card, the added power drain crashed the machine :eek: )

While the 20pin 'can' be plugged straight into the board (make sure it's the right side!) - that is not as the manufacturer intended, so random crashes... well...

Still - worth installing all the drivers and seeing if that helps
 
It is a Levicom 550watt ATX2 psu.
12v rail is rated at 20A.

Flashed the bios to the latest one and cpu is now recognized properly.
Will reinstall XP now yadda yadda :)

Post back soon.
