Athlon II X4 620 OC advice

[reignsupreme11]

I've read in reviews that the athlon ii X4 620 does not run very well with the FSB and HT link over 2100 MHz ( http://www.overclockersclub.com/reviews/athlon2_620/3.htm )


I've tried adjusting the northbridge multiplier in the BIOS to compensate, but the clock stays the same. My current clocks are at 3.05GHz CPU and 2350MHz FSB/HT.

i'm running a ga-ma78gm-us2h gigabyte motherboard.

it's working fine, i've just heard that performance could be better if i lower the fsb. does my motherboard allow this? i've heard nothing to say it doesn't.

You seem to be confusing your Hypertransport and fsb.
FSB is what you are changing and is stock 200MHz
Hypertransport is stock 2000MHz and is a 10x multiple of the FSB (the multi can be changed)
I set my HT multiplier to 8x and have my FSB at 253.3MHz. so my HT is 2026.7MHz. Unfortunately, my motherboard can't change the NB multiplier so it's stuck as is.

The FSB is linked to both your processing speed and your HT link. for you the CPU multi is at 13x so your speed will be FSBx13. You can lower this multiplier but not increase it. Same for the HT but the multiplier is stock at 10x.

core bus speed 260=3.38ghz
HyperThread x8=2080mhz aka cpuz rated FSB
NorthBridge x8=2080mhz
my cpu voltage bumped 0.1v leaky core

since your running DDR2 if its 800 set memory multi to 667mhz aka 1.66x
or if its 1066 set it to 800 aka 2x that should get you in the ballpark may need slight bump in voltage for memory if its 800standard. Not all cpu's are equal like the guy who posted ahead of me he hit the lotto!

Read up some more and figure out what is related to what in BIOS settings alttile more.
