Fx 8320 Users Here!
Hello fellow 8320 users!
I’m currently pushing my limits and just wanted to check what your settings are like. (NB voltage, core voltage, Nb frequency, HT frequency, etc.). Also, did you see that overclocking your RAM can boost frame rates by about 5% in certain games? Feel free to share your configurations—I’d love to compare and optimize my overclock.
My current settings are:
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
(Note: I’ve noticed that increasing RAM speed can raise frame rates by around 5% in some 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 share your thoughts and settings too!
Cheers
Fsb overclocking enhances core per core performance, allowing improved single core execution from an overclocked CPU. The top-performing overclocks combine multiplier techniques with FSB adjustments. My primary daily overclock setup includes:
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
For an extreme overclock (stable but rarely used due to high system strain):
FX 8370 @ 5.5Ghz on Sabertooth 990FX R2.0
CPU FSB BUS Frequency: 200
CPU Ratio: 27.5

Uncertain about the rest unless I restart 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
