Overclocking Fx 8350 Help
Overclocking Fx 8350 Help
i've been pushing my Fx 8350 overclocking and thinking about switching to intel soon, so i decided to have some fun.
mobo: asus m5a99x evo r2.0
cooler : corsair h100i v2 with four fans all directed out the top of the case.
case HAF 932.
currently i'm reaching 4.8ghz at 1.4625 volts, fully stable. idle between 23-27c maxing out to 47-55c.
what adjustments should i make to hit 5.0-5.1ghz? should i experiment with higher voltages, though most are set automatically except for my cpu/nb at 1.2750?
my aim is 5.0-5.1ghz.
also, i have a fan on the vrm, one on the southbridge, and another small one on the back of the cpu socket to help dissipate heat.
I'm a bit confused about the last sentence. Did you mean to say "Offset mode is also important when using 5.0GHz or higher"? Also, I checked my motherboard—Asus M5a99x evo R2.0 with a 6+2 power phase—and everyone agrees it's a solid board. It can handle 5GHz if the cooler and chip are good. I'm trying to understand your advice better so it's easier for me, sorry for the trouble. Thanks for your help.
Sure, please let me know if you need more detailed examples such as "try this voltage etc." Thank you again.
For the Higher OCs to support the CPU, navigate to DIGI+ Power control in Bios. Set LLC (Load Line Callibration) to high and adjust CPU current capability to 120%. This should assist.
Turn off turbo mode and deactivate any C1 or other sleep states that might be active. These are merely power-saving measures that could interfere with a stable OC.
Also turn off Cool and Quiet modes.
If an OC fails, increment Vcore in steps of .010V and retry until stable. Monitor temperatures closely and avoid exceeding 1.45V on the core.
You might achieve speeds around 5.1 or possibly 5.2GHz. Your temperatures will influence this outcome.
Thanks "MeanMachine41" I've already disabled all those settings and I have an LLC on ultra high. "Don't go above 1.45V" I notice a lot of people exceed this, I'm currently at 1.481v, and when I increase the voltage I just hit the + key once up. If I try to type a voltage like 1.465 it just rounds off to the next highest like 1.475. I also have a Corsair H100IV2 and seen many people have these at 5-5.2ghz. Thanks.
You're taking risks and planning for improvements, that's great. I understand some people have managed to reach 1.5V on the core but still faced stability issues under load. It seems your VRMs might not be up to the task, possibly due to variations in chip performance. Offset mode is another factor to consider, especially at 5.0GHz and above.
Certainly, I understand your confusion. The statement about offset mode at 5.0GHz or above seems related to adding 0.10v. Your motherboard is an Asus M5a99x evo R2.0 with a 6+2 power phase. I checked various sources and everyone agrees this board is solid for 5GHz, provided the cooler and chip are suitable. I'm doing my best to follow your advice so it's easier for you. Thank you for your patience.
Everyone can attempt a slightly higher setting occasionally and conduct extensive testing along the way. It's not a strictly scientific approach, I understand, but there are simply too many factors involved. Max suggested a recommended voltage of 1.5v for FX, so as long as your cooling system is adequate, you should be fine until that voltage is reached.

I'm a bit confused about that last sentence. "As undoubtedly you know." Offset mode is also relevant at 5.0GHz and above, right? Also, my motherboard is an Asus M5a99x evo R2.0 with a 6+2 power phase. I searched everywhere and everyone says this board is solid and can handle 5GHz if the cooler and chip are decent. I'm trying to understand your advice carefully so it's easier for me, sorry to be bothered. Thanks for your help.
As CountMike mentions, there are too many factors involved. When I say "As undoubtedly you know," I meant not every chip will reach the same performance level. While some have hit 5.2GHz on that chip, most haven't.
To ensure stability, stress test the system after each BIOS update while monitoring temperatures. You'll eventually hit a breaking point and won't be able to stabilize no matter what you do.
Just make minor adjustments to voltage and frequency until you reach your maximum possible speed. For stress testing, I use AIDA64 with HWMonitor.
I don't have your exact specifications and only the CVFZ, so I'm unsure of its full capabilities.
I should have been more precise about Vcore offsets when increasing by .010V. Sorry for the confusion.
