Are these Settings Safe??

I just got the FX-8320 and heard it has great overclocking abilities so I tried!
Note: I know most basics about overclocking, voltage and watching temps.

First off my specs.

-Crosair CX 750w PSU

-M5A97 R2.0 MOBO

-FX-8320 CPU

-Ballistix Sport 8GB DDR3-1600 (PC3-12800) CL9 Dual Channel Desktop Memory Kit (Two 4GB Memory Modules)

I set my multiplier at 18x
and my FSB to 205, I am now rated at 4.1Ghz

I know memory frequency is also changed when overclocking that much, I'm not sure how though. I currently have it set to 1640 and my CPU/NB frequency set to 1640 as well.

My CPU voltage in manually set to 1.45Volts


Here's some pictures of my overclock, before I start the prime95 test, I wanted to make sure if it was safe. I have know idea how to match the memory clocks to a certain cpu overclock. I heard it had to be a certain ratio or something like that.

60C temps are fine while running prime. Raising the multiplier is no big deal, but raising the FSB overclocks all PCI/PCIE components and your north bridge and can cause lots of stability issues with integrated components (audio, network, usb) if you go more than 4-5%

Memory frequencies will also scale up with the FSB overclocks which is why 1600 is no longer available, as you no longer have 16x100. Additionally if you pump your FSB up more than a few%, you will most likely need to scale down the HT to be within spec for your particular CPU.

All in all FSB overclocking doesn't give significant enough performance improvements over a multiplier increases for the headache required to get a functional and stable overclock and is more...

I basically don't know what to set the Memory Frequency, CPU/NB Frequency and HT(HyperTransport) Frequency)

I changed all three to around 2060. and after I chose save and restart, my computer wouldn't turn on, it just powered up and beeped one long two short. but then I read this has to do with the vga. I never gotten this before until now after the major frequency changes. I restarted my computer again and it start up normally again.

Were the temp SS's taken at Idle, or at Load, and am I safe to Assume the ambient temp's are int he low 70's?

As far as a "safe" overclock. If you got the system that far, its safe. I prefer to find a "stable" overclock myself. As for stability, run the OCCT power supply stress test and see if you BSOD in the first 30 seconds. If not, then watch the temps for the first 20-30 minutes to make sure your fan can keep up with the cooling. If all seems well let it run for 8 hours to ensure proper operation.

For CPU/NB, I would leave that alone.

For HT, you can try bumping that up, but it causes more stability issues than performance increases.

For Memory frequency, you should leave them at stock settings unless you are using an onboard GPU. The raw CPU performance gains are negligible.

I heard you need to lower the HT to make it stable, cause once you raise the multiplier or FSB then it automatically raises, so you'd need to lower it back to 2000-2600 and as for the memory freq, the option to choose 1600 isn't there anymore, after raising the clock settings or multiplier it all became higher digits.

I still recommend the power supply torture test using OCCT. That particular test loads your RAM to 80-90% cpu to 100% on all threads, a furmark like test to max your video card, and does sequential read/writes to all physical HDD's at the same time.

This is a great test for gaming stability as prime really only stresses the CPU.

My graphics card and power supply is tested and fine :p only needed to see how well the cpu can hold up. Seems like I get about 62c on 4.2Ghz with prime95, I just left it at 4.0 for longer use. Thanks for your help.
