Does XMP lead to increased core temperatures?
Does XMP lead to increased core temperatures?
You might adjust the timing for different speeds, and a 3200 mhz cl14 memory could operate quite low at 2500 while retaining much of its performance.
This raises the question of whether they have been low before.
Hi,
I recently achieved a stable overclock on my i7 7700k at 4.9GHz with 1.32v and default RAM settings. The next adjustment was to turn on XMP, which increased core temperatures by about 5-15°C. I’m wondering what might be causing this rise and how to fix it. Should I manually adjust my RAM or keep XMP active while lowering VCCIO and System agent voltage? My temperatures without XMP are around 75-80 during stress tests, but when XMP is enabled they jump to 85-95!!!!!

I’m on board with you. I’ve seen similar results with a 70C processor without XMP, using Noctua D15, but once XMP is enabled the temps spike dramatically. This is surprising, especially since my 2500k at 4.5°C never exceeded 60°C. It’s a bit of a surprise to me about spending so much on higher clock memory. I think I’ll stick with stock clocks until after my new upgrade.
I finally resolved the issue after many attempts. I reset the BIOS to default optimized settings (not CMOS clear). Then I manually adjusted my CPU. Everything worked smoothly. Next, I experimented with my RAM, beginning at its recommended overclocked speed but reducing the MHz as temperatures rose. Gradually increasing the RAM speed caused higher temps until I relaxed the timings, which stabilized the temperature. Eventually, I matched the desired XMP frequency through manual adjustments.
