I had decided to return my AMD parts and get Intel 12900KS.
I was on the fence about DDR4 vs DDR5 but have done so much art swapping and selling the last year, I am going all Intel and had some early experience with Alder Lake and a 12700K almost 4 months back with both DDR4 and DDR5.
The memory of fast DDR5 6000 to 6200MHzMHz seemingly causing a 12700K to run 12-15C hotter doing a large data set variable OCCT test with same exact VCORE caused me to stick with DDR4.
Even when I ran DDR5 at SPD spec 4800MHz, it was better, but CPU temps were still at least 5to 7C higher.
Same exact LLC and vcore and clock speed and HT off.
The motherboards were an Asus Tuf D4 Z690 with DDR4
And for DDR5, they were Asus Z690-A Prime DDR5 and Asus Rog Maximus Hero. I had same exact experience of hotter CPU thermals running exact same test on each vs the Tuf DDR4.
Does DDR5 especially fast DDR5 really cause Alder Lake CPUs to run hotter all else being equal or just a coincidence?? Could it have been the Asus Prime Z690-A and Asus Rog Maximus Hero motherboards just cause Alder Lake to run hotter at same settings as opposed to Tuf?
I ran out of motherboards to try and do not really feel like more part swapping once I finalize this 12900KS build. I did not want any brand other than ASUS and Maximum Hero had other problems like the recall and Prime-A supposed to be a good board like the Tuf, but DDR5 with no WiFi and different color. It ran hotter on both.
Is there any truth to it. Does fast DDR5 work the IMC much harder to generate more heat in Alder Lake CPUs even though it is running in Gear 2??
Do the modules run hotter being the VRM for the DIMM now on them and with a large Noctua NH-D15S cooler could the extra heat generated form RAM being so close to CPU cause 12-15C higher temps especially with extra heat generated at fast speeds.
