Horrible i7 8700k Overclocking
Horrible i7 8700k Overclocking
I own an i7 8700k that struggles to reach even 4.7ghz stability with asrock LLC (which is disabled/llc for other brands) and at 1.33 volts, 1.1 VCCIO, 1.15 VCCSA. I've checked various RAM voltages to rule out hardware issues.
I reinstalled the graphics driver using DDU but the problem continues.
RAM: G skill ripjaws: F4-3200C14D-16GTZ
Mobo: Asrock z370 gaming-itx/ac (best chokes for all z370 boards, no idea why I'm seeing these results :O)
CPU: i7 8700k
PSU: EVGA 750W Gold G3 PSU
Begin by keeping the RAM separate, using the XMP profile only when necessary. You can adjust it later if you really want to push its limits. In an Intel system, this won’t have much impact.
Adjust the multiplier according to your goal. Open the BIOS and place it around the middle value. On my motherboard, MSI has ten levels with a line indicating whether voltage will increase or decrease under load—10 being the lowest and 1 the highest. At 5.1 I chose 3, just above even. At 4 it was even. I hope your BIOS also shows a graph for reference. For 4.7, a value a notch below or equal works well.
Configure the CPU Core/GT Voltage Mode to Adaptive + Offset, leaving the offset at auto. You don’t need to change anything else.
are you attempting to boost your ram and cpu simultaneously? try configuring your ram to jdec ddr4 2133 and observe if it aids in cpu overclocking. once you reach its limit, gradually increase your ram speed until you match your XMP settings. if this doesn’t work, it might mean you’ve missed the silicon opportunity.
Begin by leaving the RAM alone, using the XMP profile only when necessary. You can adjust it later if you really want to push it overclocking. In an Intel system, this won't make much of a difference.
Adjust the multiplier according to your target performance. Open the llc and place it somewhere in the middle. On my MSI motherboard, there are ten levels with a line indicating whether the voltage will increase or decrease under load—10 being the lowest and 1 the highest. At 5.1 I chose 3, just above even. At 4 it was even. I hope your motherboard BIOS also provides a graph for reference. For 4.7, a value a notch below or equal will suffice.
Configure the CPU Core/GT Voltage Mode to Adaptive + Offset, leaving the offset at auto. No need to tweak it further.
Set your vcore carefully. Begin with a low value and gradually increase until stability is achieved. For 4.7, you likely won't need to set the vcore very high.
Avoid altering any other voltages—keep it straightforward.
