Have questions about overclocking AMD?
Hi guys, I'm trying my first overclock for my AMD Athlon x4 860k CPU with a turbo of 4ghz. The stock is 3.7ghz, but I'm not getting a stable 4ghz even at 1.4500v base. The stress test I'm running is Prime 95, and instead of the expected results, I get a blue screen error saying "CLOCK_WATCHDOG_TIMEOUT." Please help. (Also, I'm using AMD Overdrive for this overclock.) CPU: Athlon x4 860k | Cooler: Corsair H55
initial attempt with AOD for overclocking is recommended since it introduces instability in systems during overclocking. Employing software for overclocking adds another potential failure point, making direct BIOS/UEFI adjustments preferable. After configuring BIOS settings, please retest and inform us if the same BSOD persists at those settings.
That voltage is too high. Try keeping under 1.375. The overclock might not have sufficient NB voltage. Also, what are the temperatures? The CPU could be overheating at that level. Are you sure? The setting is 1.4125v Stock—does that seem normal for a 860k? Based on Coretemp and AMD overdrive data, I was seeing 35-45°C during stress testing before it crashed.

start with AOD for overclocking since it introduces instability when you're already pushing systems to higher speeds. Using software for overclocking adds another layer of risk, making direct BIOS/UEFI adjustments more reliable. After configuring the BIOS settings, please retest and inform us if the same BSOD persists at those settings. Thanks, I'll follow up with a reply.
At 1.41v you should reach 4.4-4.6ghz. I recommend water-cooling if you want that speed. Make sure you have two voltage options to keep the CPU stable. The CPU and CPU-NB voltage need some adjustments.
At 1.41v you should reach 4.4-4.6ghz. I recommend water-cooling if you want that speed. You’ll need two voltages to keep the CPU stable. The CPU and CPU-NB voltage settings require some adjustments. I’m using a Corsair H55 with a single liquid cooler.

At 1.41v you should target 4.4-4.6ghz. I recommend water cooling if you want that performance. You’ll need two voltage options to keep the CPU stable. The CPU and CPU-NB voltages require some adjustments. I’m using a Corsair H55 with a liquid cooler, but multiple air coolers can outperform it. The water cooler here is a compact design with limited cooling capacity. I was suggesting larger radiators like the Corsair 100 or higher. I’m not pushing upgrades since your CPU isn’t worth the cost.
Not necessary. While the H55 is a weak AIO it will do for a light to medium overclock especially if there is good air flow through the case. Your voltages and the frequency they can reach are a bit off in my opinion also for the newer AMD CPU's. 1.416v usually will not get you to 4.4 GHz unless you have one of the top overclocking chips But this is all subject to the silicon lottery.
@ OP have you had a chance to set the clocks and voltages in the BIOS and test yet?
