Fx 8320 Users Here!

Hello fellow 8320 users!
I am trying to over clock right now and just test my limits.
I was curious as to what all of your settings were (NB voltage, Core Voltage, Nb freq, HT freq, etc.).

As well as if you noticed OCing your ram helps or anything like that. Feel free to share your settings! I'd love to compare and try and maximize my overclock.
Right now my settings are as follows...

CPU FSB FREQ: 200
CPU Ratio: 22.5 (4.5 ghz)
Cpu-NB Ratio: 12 (2.4ghz)
DRAM Frequency: 1866 Mhz
Dram timing: Link
Advanced dram config:
Command Rate: 2T
Tcl: 9T
Trcd: 10T
Trp: 9T
tRas: 30T
(I have notice Overclocking my Ram increases Frame rate by around 5% in certain games)
CPU Voltage: 1.431 (+0.015)
CPU-NB Voltage 1.208V (-0.06)
DRAM Voltage: 1.624V (1.620V)
NB Voltage: 1.15V

Please feel free to share your thoughts as well as your own settings!
Cheers

Fsb overclocking helps with core per core execution (single core performance). So by raising the CPU FSB BUS Frequency you can get better single core execution out of your overclock. The very best overclocks are a mixture of both multiplier and FSB overclocking.
My main everyday overclock is:

FX 8370 @ 5.05Ghz on Sabertooth 990FX R2.0
CPU FSB BUS Frequency: 214
CPU Ratio: 23.5
Memory Frequency: 1987Mhz
CPU/NB Frequency: 2556Mhz
HT Link Speed: 2556Mhz
DRAM Timing: 9-9-9-26
CPU Vcore: 1.462V
CPU-NB Voltage: 1.25V
CPU VDDA Voltage: 2.60V
DRAM Voltage: 1.60V

Extreme Overclock (stable but never really use due to very taxing on the system):
FX 8370 @ 5.5Ghz on Sabertooth 990FX R2.0
CPU FSB BUS Frequency: 200
CPU Ratio: 27.5
Memory Frequency: 1866Mhz
CPU-NB Frequency: 2400Mhz
HT Link Speed: 2400Mhz
DRAM Timing: 9-9-9-26
CPU Vcore: 1.55V (set at 1.55V, but have noticed that it jumps to just over 1.6V under load- one reason I don't use this overclock other than to see how far I could push my system)
CPU-NB Voltage: 1.25V
CPU VDDA Voltage: 2.6V
Dram Voltage: 1.5V

Speed - 4.5 Ghz
CPUV - 1.40V
NBV - 1.25
RAM: 1600

Not sure about all the others without booting back to BIOS.

In the past when I raised my FSB frequency I had to reset my cmos battery because it wouldn't turn on... Probably because I raised the FSB and only the FSB... So what would be a good FSB frequency/core multiplier to start out with?

FSB overclocking is good in that it will allow for better single core performance, however it is also harder on your system as it overclocks several things all at the same time. Not every motherboard is capable of fsb bus overclocking as you need good cooling on the NB and VRMs. Your also going to be raising your RAM clocks so you will have to adjust voltage, timings, and make sure your RAM has sufficient cooling. I am running a Sabertooth 990FX R2.0 which is one of the best boards you can overclock on and has more than sufficient cooling and heat sinks on everything. I also have 8 120mm case cooling fans pulling cool air from the front, side and bottom of my case and pushing the hot air out the top and rear of the case. All my components have very good air flow.

Once you know you have the cooling, power phase, and psu (I have 1000W 80+ Gold) necessary for overclocking I like to get at least 300Mhz of an overclock by fsb for any overclock over 4.6Ghz. I have had higher fsb overclock, but noticed at least with my particular chip that I was getting very near the same performance with 500Mhz fsb as with 300Mhz fsb (the law of diminishing return with overclocking), so I backed off to 300Mhz and increased the multiplier as it is easier on the system as overclocking with the multiplier is really targeting just the CPU.

Overclocking using fsb is very good for increased performance, but must be done slowly and carefully as there are so many things to adjust to get a solid overclock and much higher risk of damaging a component as you are raising the speed of the NB, CPU, and RAM all at the same time. You have to adjust the CPU-NB voltage, the Vcore, the DRAM voltage and timings to get everything just right. The end results can be very rewarding though. When I overclock a customer's computer I always do multiplier only as it is safer. A FX 8370 @ 5Ghz multiplier only will yield Cinebench R15 scores of 119-120 single core and 790 - 800 multi-core. With the 5.05Ghz overclock I have I get Cinebench R15 scores of 122 - 124 single core and 810 - 820 multi-core. Its a very nice bump considering the clock speeds are nearly identical.

This is a very good video as an introduction to overclocking using fsb and multiplier, plus the guy is humorous which is always a plus
