You are using Venice 3000+ which means you have a max multiplier at 9. So, in order to go 2.8ghz, you need RAM and mobo that can do 311HTT. Based on your value ram, the best bet is to lower your HTT Multiplier to 3x, and then set your ram to DDR333, and then chose 311HTT. Then prime.

If your mobo can sustain 311HTT and your CPU can run at 2.8ghz, then this should work.

Unless you can get some TCCDs that are real good, and run it at 2.7-2.9Vdimm, you can try to set the memory to DDR400 to run at 1:1. If not, you need to run with RAM divider as mentioned above.

There's no guarantees that you could hit 2.8ghz coz there's no such thing as certainty in overclocking. We can only give you the guidelines mentioned above.

The on-die MCH on the A64 cpu can't handle HTT above 1ghz properly and hence, will cause random issues such as reboots or crashes to occasional BSoDs.

That's as far as I understand, if you wanna know more, might need to ask those who takes EE as their major.

IO Guy, mine is A8N32 SLI...

Proc: AMD X2 3800
Core: Manchester
Week: xx
Mobo: Asus A8N32-SLi Deluxe
VCore: 1.6V
HTT: 260
FSB: same as HTT.
PSU: Silverstone ST65FZ
CPU HSF (Brand & Type): BigWater
RAM (Brand): Mushkin Enhanced RAM (UCCC)
Current Lantency (OC'ed): 3-4-4-8
VDimm: 2.8V
RAM FSB: 260MHz aka 520MHz.

Not sure how it's gonna help you, but you could use them as baseline for your overclock. My Manchester is not a particularly good chip though.

I think no point in raising it further beyond 1.6V as the quality of my chip is maxed at 2.6ghz.
