I still have some reading to do I guess in terms of what you mention about maximizing your ram vs the divider (have to figure out how to work out the math).
Thanks again for the response.
*M3A32-MVP Bios 1102 (currently at 255FSB/11Xmulti)
*AMD Athlon 64 X2 4800+ Dual Core (OC'd from 2.5 to 2.8ghz on stock cooler running mid 40's loaded)
*2GB Crucial Ballistix 8500 CL5 (1066mhz) (currently at 956mhz and 4-4-4-12)
*eVga's e-Geforce 9600 GT OC Edition (OC'd even more to 735/1050)
The guide really only applies to the new architecture, so increasing the FSB while lowering the multi/NB/HT and putting the memory on a divider is still the most effective way for your X2.
Also, the math is a little bit different, since the X2 doesn't have an L3 cache, and even though the NB and HT aren't directly linked per the BIOS, they still behave differently than the Phenom architecture.
Here's the math for anything prior to the Phenom:
(CPU Multi) * (FSB) = (CPU Freq)
(CPU Multi) / (Memory Divider) = (Divisor Ratio) (**ALWAYS ROUND UP HERE** - see below)
(CPU Freq) / (Divisor Ratio) = (RAM MHz) ( * 2 = DDR MHz)
(NB Multi) * (FSB) = NB Freq, HT *MUST* be less than NB!
**For the memory divider, you must round UP to the next higher integer - even if you end up with a .1 (i.e. 11.1 = 12, 10.4 = 11, etc.) So, any time you have a decimal here, you have to round up to the next higher whole number for the math to work correctly...whereas, with the Phenom architecture, you can't round or the math doesn't work (this one stumped me for quite some time till I figured that one out!!!
Good job so far - everything else is pretty much the same, especially finding the MAX for each component (where everyone should start), so get familiar with it all and you'll go far!
