I know I need to raise my voltage now, but where do I do that? Again, I'm sorry for being such a n00b at this, but you gotta start somewhere right?

That's right, SpyKe, but no apologies necessary.... it looks like your voltage controls are under the PWM Setting.

By the way, have you read through the AM2 Overclocking Guide?:

http://www.overclock.net/amd-general...ocket-am2.html

.... a lot of good info there that might be helpful to you.

Ok, now I have a problem. I don't have a CPU VID Control option.

My BIOS are updated from the DFI site for the date of 03/05/2008. What now?

According to the mobo manual, the field for CPU VID Special Add "provides more options to further adjust the voltage of the CPU"

Ok, if that is where I change my voltage, why is there huge numbers when that is selected? Its not like 1.2 blah blah GHz. It has 4 digit numbers. Hold on, I'll take a pic to show you guys...

SpyKe.... I've been doing some looking, but I haven't come across any other places to change vcore.... what is an example of a value that comes up in that field?

Teufle · 07-17-08

Howdy, I happen to have that exact board. You increase the core voltage by an odd little value called "cpu special add" +175.OMV is 1.45 ,to give you a base line.
And to check your Voltage use a program like CPUZ(in widows).

NOTE: The value will not show in the bios when you first change it, but it will show when you restart.

After thought. Using this MOBO I achieved a 3.31ghz (perfectly stable) with a AMD 5000 BE, give it a go

(Voltage was 1.48 when I did so, and I kept it that way for months).

Thanks for the help, Teufle.... good info!

No problem. People helped me all the time, if I can help someone else (especially with a problem I was having) Its the least I can do.

Ok now trying to follow neoseeker, they got it to 3.396GHz. Thats a nice OC so I would like to try to also get it at that.

To get this result:

manually set the HT speed to 283MHz for both the processor and the chipset
set the HT multiplier to 4x - again, for both processor and chipset
leave the Vcore alone, the automatic settings do a great job (or manually ser for 1.45V)
set the DDR voltage to 2.1V
choose the "DDR667" memory speed setting, this will map to 849MHz with a 283MHz FSB
set the memory timing to 4-4-4-12
manually force the "2T" option

So this is what I have done so far: manually chose the DDR667 setting, set the timing to 4-4-4-12, manually forced the "2T'" option, dropped my multiplier to x12.

Now what is the HT multiplier, the HT speed and how do I change it?
