More Ram Sticks you have the higher the CPU Temps?- Prime 95

[WinnRig]

All ram on a Haswell CPU is overclocked to meet the manufacturers Rating which is why I have this in the OC section.

2 Questions
1. Does Running less sticks of ram lower CPU Temperature under Stress [See my Testing Below]
2. Does Running Lower GB of Ram also lower CPU Temperatures. Example 2 sticks of 4gb ram verse 2 sticks of 8gb ram.

I recently had a problem getting 32gb of Corsair Veangance Pro 2400mhz ram to run at it's rated XMP 2400mhz Speed. I solved it by buying PNY Anarchy 2666 Ram with looser timings. CL12 verse CL11.

My Testing results for my 8gb Corsair Modules were as follows 8gb [1X8GB] and dually 16gb [2X8gb] were stable at the XMP 2400mhz setting but with 32gb [4X8gb] installed it failed OCCT within 6 seconds and had to be underclocked to 2200mhz.

I went to the forums for an answer how to make 32gb work and went to the Motherboard Manufacturer. The forums told me to tweak voltage settings [I tried unsuccessfuly]
The manufacturer ASROCK suggested that I test each module at 2400mhz so I did and I noticed an interesting thing.

When I ran Prime Medium Blends all 8 Cores with one stick [1X8gb] the Temps stayed in the 50-60 range
When I ran Prime with 2 8gb Sticks the Temps Went into the 70s Highest a low 80. When running prime with all 32gb modules [4X8] it ran close to 100c no throttling

This is something that I never came across in the forums and could account for why people have such varying reviews of different Coolers.Makes me wonder Is my testing result a universally applicable?

In addition I was wondering if this cooling curve applies if you are using varying sticks of Lower MB Ram. Example my tests were done with 8gb Ram. Would the same amount of 4gb Ram sticks run the CPU cooler in Prime.

Possibly as the IMC will have to work harder which could increase CPU temperature.

What he said. It is not the amount of RAM you have, its how many slots you occupy. If you only occupy half of your RAM slots, that means two of the slots have no additional voltage. I would not think it would effect temps THAT much...but I have also never tried to run with anything other than two sticks of RAM. I would suggest getting rid of XMP, because that can cause overclocking issues. Disable it, and set things manually.

My Memory is running rock solid with the XMP Settings

More sticks are more stress on the MC in the CPU, MC and CPU itself work harder pull more voltage - results in more heat. Same when running high data rates at tight/low CL - more stress to MC = more heatAlways best to use as few sticks as possible while maintaining the abilty to run the greatest channels you can. i.e. on a dual channel mobo2 sticks if possible - only fill all slots if maxing out the mobo.
