Is right, i'd say.
I'd been stuck at 210(FSB) until i reduced the HT-link multiplier from [5x] to [4x] and reduced the FSB:RAM ratio.
I'm now able to run at a FSB of 260, with a multi of [11x] which=2860.
[260x11=2860]=[(FSB)x(clock multiplier)=(final clock)]
with very little tweaking so far. confident it can go further with more tweaking.
It's quite poorly thought out how the RAM:FSB ratio is represented in the BIOS. it's default is 200, which is 1:1(locked),(synchronous) with the FSB. As you raise the FSB, the memory will raise with it.
"ie":Default. The ratios are locked synchronously at 200/200.
If you run the the FSB at 220, your memory will as well except, ddr.[220x2=440]=[(FSB)x2=(ddr clock)].
You can also unlock the ratio, allowing you to run asynchronously. Though, this makes my computer unbootable and must clear the cmos:
The settings (133,166,200,216,233,etc) are are ratio's of a base 200.
Ratios being [.665:1 , .83:1 , 1:1 , 1.08:1 , and 1.165:1] respectively.
So, if you reduce it from 200 to 133 you will have a ratio of [Mem .665 : 1 FSB] [133:200]
So, if ratio = [166:260]=[(memory clock):(FSB)], your memory will be running at ddr~433.
[2860/11x.83x2=260x.83x2=(ddr clock)]=[(final clock)/(clock multiplier) x (ratio) x 2 = (FSB) x (ratio) x 2 = (ddr clock)]
Check your RAM's rated speed to figure the final desired value.
The available voltages of 2.6~2.85 are quite limited, so make sure you get your timings right. you wont have much margin of error for you to push your memory out of spec.
I run all of the spread spectrum setting=disabled . I've found this to greatly aid overclocking and stability.
Try to keep your HT-link clock speeds near stock, the voltage is not raise-able through the bios.
Remember, the HT-link clock is a default of 1000
[5x200=1000]=[(HT-link multiplier)x(FSB)=HT-link clock)]
If you raise your FSB your HT-link clock raises synchronously as well. Almost the same principal as with the memory, but this can not be unlocked. only multiplier changed.
So, i set it at [4x260=1040]=[(HT-link multiplier)x(FSB)=(HT-link clock)]
with [~+/-"60Mhz"] of 1000, being my initial goal.
Their website sucks too, this was almost impossible to find with out using newegg's link.
I'm running the 9.7.07 Bios. a highly recommended upgrade.
