This could increase the power usage a bit (and hence also the temperatures), but since I am using Crucial Ballistix DDR3L memory running 1,35V (even when activating the XMP1 profile!) I don't expect any (significant) negative effect.Īfter applying these changes I've notice that the CPU speed is limited to something between 4,10 and 4,20 Ghz instead of the default 4,4Ghz (with default BIOS settings). I've activated the XMP1 profile of my RAM.It might be even possible to decrease the negative offset even further (-0,070V or maybe even -0,080V). But I didn't have any system crashes during testing yesterday evening, nor in idle, nor in stress. This seems to run stable, however I didn't do long duration tests yet. Instead I've used a negative offset of -0,060V. I've put the VCORE voltage on 'normal' instead of manually adjusting it (because otherwise the voltage remains all the time the same instead of dropping when idle).You can find a summary of the proposed settings in this official Intel document:Ģ changes I've made on my Gigabyte UD3H mobo are: Next I've applied the recommended Intel settings from Ken (Intel support), which can be found back in the topic mentioned before (/message/260210# 260210 260210). I have to admit that besides the new CPU I'm also using other thermal paste (Arctic Silver 5), but this shouldn't change the temperatures a lot: maybe 1☌ or 2☌. Without any BIOS adjustments I'm getting temperatures beginning 80☌. I've done some (short) tests with Prime95 small FFT's and I can confirm that based on these tests, the max temperature seems to be 10☌ - 15☌ lower. The idle temperature is around 25☌ regarding the Intel tool. In average the temperature was below 70☌. These temperatures are better than with Prime95, but still very high.Īfter running Intel Extreme Tuning Tool for 1 hour, the max temperature was 73☌. Temperatures increased until 71☌, core voltage increased until 1,269V (measured with RealTemp and HWMonitor). In the meantime I was able to do a stress test with the Intel Processor Diagnostic Tool and the Intel Extreme Tuning Tool (10 minutes). I've done the test with the default BIOS (F4) and the newest BIOS (F7) from Gigabyte. I don't dare to overclock with such a temperatures.
What is going wrong? Why do I get such a high temperatures during load? 90+☌ without overclocking is dangerously high. Next it takes 2 minutes to further decrease to 19☌ (idle). As soon as I stop the test the temperature decreases instantly as well: within 1 second the temperature is decreased till 30☌. The cpu-cooler is at startup running at 550rpm, during load it increases to 1250 rpm.Īnother thing I've noticed is that the temperature increases instantly from 18☌ to 90+☌, within 2 seconds. The test is done immediately after a cold boot. The first one (lower one) is achieved by running the Prime95 Blend test (max temperature after 3 minutes around 57☌), the second one is achieved by running the Prime95 small FFTs test as described above, with temperatures above 90☌. In the graph below you can notice 2 temperature peaks. Remind however that HWMonitor and RealTemp are showing higher temperatures (around 6☌ higher).Īs soon as I use Prime95 with the small FFTs test (latest version) to put the cpu under load, the cpu temperature increases instantly to temperatures around 92☌ (HWMonitor is even showing 100☌ from time to time). In what follows I'll continue with the Gigabyte app temperatures, as the graphs are made with the Gigabyte app. The Gigabyte app shows even a temperature of 18☌.
Idle I'm getting temperatures between 20☌ and 26☌ (depending which core). The last one shows slightly lower temperatures then HWMonitor and RealTemp. The temperatures are measured with HWMonitor, RealTemp and the Gigabyte System Information Viewer app. I am using a Gigabyte GA-Z97X-UD3H motherboard in combination with a Thermalright True Spirit 140 cooler in order to get lower temperatures than the stock Intel cooler.

Like some other people I'm getting extremely hot temperatures when testing the processor at full load.
I have a question about the temperatures that I'm getting for my 4790K processor.
