I7-6700k overclocking issues
I7-6700k overclocking issues
Hi guys,
I currently have an i7-6700k with a h100i v2 water cooler, paired with an Asus Z170 Sabertooth S motherboard and 16GB 3000MHz DDR4 RAM.
I attempted to overclock the processor but whenever I adjust something it won’t stabilize and just stays on a black screen with the fans running. This is unexpected. I thought it should work, but it doesn’t.
For the overclock attempt, I selected the xmp profile, set the multiplier to 42 (starting point), and changed the voltage from 1.28 (standard for my CPU) to 1.325. Then I tried 1.35, but again it just stayed on a black screen briefly before I panicked and turned it off.
Apologies if I’m being too blunt, and thank you for any advice from more experienced users.
I've achieved a score of 42 on stock voltage without the xmp profile, but once I activate it, the system won't reboot and displays an overclocked failed message. Is this related to RAM or the motherboard? Also, what temperatures should I anticipate with the stock settings at 1.28 V and 70 degrees in some games? My H100i v2 CPU is cooling well and my GPU is water cooled.

I achieved a score of 42 on stock voltage but without xmp, once I turned on the xmp profile it wouldn't reboot and it showed overclocked failed... Is this related to RAM or the motherboard?
Also, what temperatures should I anticipate with stock speeds and voltage at 1.28? I'm seeing around 70 degrees in some games even though my CPU has an H100i v2 for cooling and my GPU is water cooled. Could be a memory problem when overclocking. You might want to manually overclock your RAM then.
Georgehillier shared his experience with achieving a 42 on stock voltage without xmp. Once he enabled xmp, the system wouldn't reboot and displayed an overclocked failed message. He wondered if this was related to RAM or the motherboard. He also asked about expected temperatures at stock speeds and voltages of 1.28, mentioning that he experiences high temps in some games despite having a H100i v2 cooler and a water-cooled GPU. He noted it feels quite warm for water cooling and recommended air cooling instead. He shared his own setup with a 4670K that runs stably at 4.5GHz and stays cool to 55-60°C under full load, thanks to a $25 Hyper 212 EVO cooler. He suggested resetting the BIOS or clearing CMOS initially, and mentioned that for a 6700K, the stock multiplier should be 42, with a factory turbo boost of 4.2GHz. He advised adjusting the multiplier to 43, keeping voltage at stock levels, and performing manual overclocking on RAM to prevent it from setting too quickly.
Elbert, here are some suggestions on manually overclocking RAM. You can try adjusting xmp settings before. Iyzik, you mentioned resetting to default and checking the BIOS—did you confirm the stock multiplier is 40?
Georgehillier:
Elbert, do you have any advice on manually increasing ram speed? I usually rely on xmp settings before... And iyzik, I've already reset everything to the default and checked the bios. Was my assumption about the stock multiplier being 40 correct since it doesn't factor in the turbo? Yes, but you should test just the cpu first. Once the ram is installed, change only one setting at a time. Skip XMP until you achieve a stable, solid cpu overclock that suits you.
