Angry intro: Some, or a lot, of us are very confused with the new AMD Athlon64 processor, especially in the area of overclocking.
Most of us here are very familiar with overclocking what we term a 'normal' cpu, like the Celeron 300A, Intel Pentium4, AMD AthlonXP etc.
AMD64 is really a superior cpu that really performs best when it is overclocked to it's max Mhz...but there is this thing called HTT and it seems to be a giant bogeyman for a lot of us (me included as you will read).
Mr RGone here helped a customer with this post, and I took it from there as his post MADE ME REALLY UNDERSTAND exactly how these A64's are really no different when overclocking...we are just making them too complex!
Please, take a read below, and let us know if it hits you like a ton of bricks like it has hit a few of us (and I'm sure a few that are too embarrassed to admit that they really didn't 100% understand until reading this).
===============================================
The default speed of a 3700+ with 1mb L2 cache is 12 x 200 or 2400mhz; real cpu mhz. 12 is the multiplier. 200 is the buss speed AND the speed of the memory when set to 1:1 / 200 in Dram configuration. The HTT buss speed of that 3700+ on the UT250gb if LTD/FSB ratio is set to AUTO is 4 times 200 or 800HTT buss speed times 2 for a DDR rating of 1600 for single channel NF3 boards. If you set the LTD/FSB ratio to X4 the HTT buss speed itself will again be 800x2 or DDR1600 the Default for single channel NF3 chipset boards.
Again leaving CPU/FSB Ratio at the default of 12 for your 3700+ and leaving the FSB Buss Frequency at the stock 200 and changing the LTD/FSB Frequency to X3. You will then have a processor running at its default of 2400mhz same as always. The memory will still be running at 200 (DDR400) and NOW the HTT buss speed though will be 3 X 200 = 600 HTT buss speed times 2 for a DDR HTT buss speed of 1200 or 400 under the default HTT buss speed. Now that is how that works.
It has been found that 600 to 900 HTT buss speed or 600 to 900 times 2 for a DDR HTT buss speed of 1200 to 1800 are all just fine when overclocking the Normal processor or memory speeds. That HTT buss is in nO way nearly saturated and therefore anything from 1200 to 1800 is fine as wine.
Now that is how the single channel 754 processor works and is in effect how you figure the HTT buss speed which in effect has little to do with an overclock as long as it is not below about 600 or above 900.
Now knowing that this is how it works> it makes me rather confused when you come up with other numbers for which I see no corresponding components on the board.
You do not multipy LDT/FSB Frequency Ratio times the CPU/FSB Frequency ratio to obtain any number that means anything to a Single Channel 754 A64 processor that I am aware of.
