OC FX 8350- NorthBridge

[TheIronShit]

Hey,
I recently OC my FX 8350 to 4.4GHZ, the thing is I didn't saw any change in the NB and in the HT.
my goal eventually is to get better single core performance. my question is if I need to OC the NB as well to get better single core performance, and if so how to do it without raise the TEMP because in stress test i'm on MAX (62 degrees).
my motherboard is Gigabyte 990xa-ud3.
Thanks

This info may be a bit out of date... but on an AMD phenom II, the HT link makes no performance difference at all above 2000Mhz, and the northbridge is best set at 1.5x the memory frequency.
I have memory at x8 (1600mhz) and northbridge at x12.
I also increased the bus speed from 200 to 222, which further increased the memory to 1776Mhz and the nb to 2666

Hello friend.

Overclocking the HT frequency has shown not to improve performance much on the FX series, however CPU Northbridge for L2 cache performance does.

Use must use a combination of Bus speed and multiplier. for 4.4 Ghz single core, I would use 220x20= 4400. Then set Northbridge frequency to 2400. Set HT to 2400. Set memory to lock at RAM manufacture speed. If RAM fails tests, lower ram when multiplier point or increase timings to - 11 11 11 30.

Because you have increased the Northbridge CPU speed, you have increased the L2 Cache speed and have increased single performance. Now you must give it voltage to stay stable. In voltages you will see "CPU NB core voltage" it will be around 1.25 for 8350, set it to 1.28-1.3. If tests are stable, increase Northbridge frequency to 2600.

I will tell you right now, after overclocking five different FX CPU's, the best way to increase single core is more Bus speed, Northbridge + more core frequency. When you get past 4.5Ghz, these CPU's really open up...but the same can be said for a lot of other chips as well.

My 8320 is now at 5Ghz stable. It benches the same as very expensive Intels. Good luck.
