Overclocking CPU issues following RAM installation
Overclocking CPU issues following RAM installation
I had my fx-6300 overclocked to 4.0 ghz for a while, but I thought I wasn’t really relying on it, so I turned it off. A while back, I upgraded my RAM to Corsair Vengeance Low Profile DDR3-1600. For some reason, it appeared in my BIOS as 1333mhz, so I increased the OC to 4.0 and changed the RAM to 1600mhz. Everything worked for a while, but about a week later, my PC froze. After rebooting, the POST reported overclock unstable. I lowered the OC to 3.8 ghz and it’s now running fine. Today I tried again with the 4.0 OC, but the PC froze once more. This time I checked the situation carefully: I had restarted my PC, but when it powered back up, the fans and lights were on, yet there was no display. I performed a hard shutdown and saw an unstable OC screen during POST. My question remains—why does my PC still see the RAM as 1600mhz, and why isn’t the overclock functioning properly now?
Ray Tsou shared his experience with adjusting and troubleshooting his system. He initially overclocked his FX-6300 to 4.0 ghz but later removed the overclock. He upgraded his RAM to Corsair Vengeance Low Profile DDR3-1600, which caused BIOS to display 1333mhz instead of the expected 1600mhz. After changing the RAM speed, he faced a freezing issue after a week, which resolved when he reduced the overclock to 3.8 ghz. Recently, he attempted another overclock to 4.0 ghz but encountered another freeze. He noted that after restarting his PC, fans and lights were on but no display appeared, leading him to perform a hard shutdown and recheck the situation.
It seems the new RAM isn't functioning well at 4 GHz. Check the BIOS and adjust the RAM timings accordingly, manually applying the manufacturer's suggested values if necessary. Luckily, the difference is only 200 MHz, so it won't cause any obvious issues.
Ray Tsou shared his experience with adjusting and troubleshooting his system. He initially overclocked his FX-6300 to 4.0 ghz but later removed the overclock after a brief period. He upgraded his RAM to Corsair Vengeance Low Profile DDR3-1600, which displayed as 1333mhz in BIOS. He then increased the OC to 4.0 and changed the RAM speed to 1600mhz, but faced a freezing issue about a week later. After rebooting, the system reported an unstable overclock. He adjusted the OC down to 3.8 ghz and it worked again. Recently, he tried setting the OC back to 4.0 ghz, but the PC froze once more. He noted that after restarting, fans and lights were on but no display appeared. Upon hard shutdown, an unstable overclock display appeared during POST. He sought advice on why his system recognized the RAM as 1600mhz and why the overclock was no longer effective.
This could be a comprehensive explanation.
1) AMD processors aren't designed to handle mixed RAM configurations, so if your memory is simply an additional chip added on top of another existing one, stability will likely be compromised due to the AMD northbridge's limitations.
2) Numerous factors can lead to overclocking failures, mainly insufficient voltage or excessive heat; it’s advisable to review this information before attempting further adjustments.
3) Your BIOS might incorrectly label the RAM as 1333 because it is actually DDR3 1333, but the manufacturer categorized it as 1600 and affixed a sticker claiming otherwise. You may need to visit the manufacturer's website to obtain the correct latency timings and required voltage for optimal performance.
4) Your RAM could be DDR3 1600 by design, yet it isn't compatible with AMD chips or the northbridge, so ensure your memory is listed in your motherboard's approved specifications.
