Overclocking an FX8350
Overclocking an FX8350
Here are the details you requested. The information provided outlines the specifications of the system, including the processor, CPU fan, case, and motherboard. It also mentions the user's experience with overclocking and performance observations.
Bad motherboard for overclocking. The power phase design is subpar (4+1). It's suitable only for running the 8350 at stock or turbo settings.
I own the same motherboard but with a rev 1.0; the older version works fine for overclocking, though not ideal. Most M5A97 boards have poor LLLoad line calibration (overvoltage), so I disable it. Turn off all energy-saving features and try overclocking the CPU cooler—currently I'm at 4.5ghz with 1.475 volts, which is quite high compared to other overclocks. Since load line calibration isn't possible, I increase the voltage a bit for better performance, allowing my CPU to reach 45c and using a Noctua NHD14 cooler.
I'll need to try that out later. I'm using a similar Zalman cooler on my system and seeing the speeds as described before.
I'm planning to disable the load line, thanks for the suggestion.
Another thought—does the Noctua really justify the higher cost? I was considering switching from an Antec 900 to a Silverstone Raven RV03 for better heat dissipation at the top, and to avoid overheating the PSU with a future 370 xfire configuration. In my mind, the Zalman would be preferable since it lets you position the CPU fan to direct airflow upward with the other fans.
I had a zalman 9900aled, it couldn't manage the chip with overclocking. It was hitting g 70c on the socket and 60c on the CPU, which are the limits for these chips. Now with this noctua cooler, I'm achieving the temperatures I mentioned earlier. I'm currently running an Intel burn test and I'm hitting 50c on the socket, which is actually lower than I expected.
So yes, noctua is worth it. I managed to get one in used condition.
Regarding the air direction, I used a cooler 212evo and it didn't make any change whether I blew air out the side or straight up.
Well, we'll find out what remains after improving my case/CPU and adding another GPU.
Maybe I'll get one, but it's uncertain. I'd need to try the new configuration first to determine if it's necessary. I'd prefer to keep what works and reuse it. This system has been performing well for four years now.
