I also have a FX-8350 CPU
Right now I have the board running at these clocks
I have the CPU Multiplier at 19.5
I have the CPU FSB at 220
which gives me 4290Mhz on the CPU and runs the memory at DDR3-1760
I had the FSB up to 225 which gave me DDR3-1800 but I had a few crashes.
I was reading else-where in this thread that HyperTransport Clock and the North Bridge Clock should be the same and that they should be somewhere around 2600Mhz.
This is where I get a little confused. My HyperTransport Clock is set to auto in Bios and AIDA64 tells me it set at 13X and is 2860Mhz, the North Bridge Clock is also on Auto and AIDA64 tells me it set at 11X and is 2420Mhz.
So I want to up my FSB to 234 and lower my CPU multiplier down to around 18X
Would I lower the Hyper Transport clock multiplier from 13X to 11X that would give me 234 x 11 = 2574 Mhz
And leave the North Bridge Clock multiplier at 11 so that it matches the HyperTransport Clock ?
Thanks for listening.
Why are you using the FSB to OC? Manually adjust the multiplier for the CPU to the desire value, then adjust the CPU-NB to 2800 and leave the HT Link at default.
As for the ram; use the XMP if available (E.O.C.P.) for 1886MHz, if not, do it manually. Same goes for the voltage if XMP (E.O.C.P.) is not available.
After that, you have to increase the voltages for the CPU and the CPU-NB to whatever is stable.
