I think my memory temps are too high

With bios 0816, I tried tuning this GSkill 7800 kit again, F5-7800J3646H16GX2-TZ5RK, on my MZ790E. Did not succeed before, but now I am thinking it was my Ram temps. Ramtest failed but noted temp around 63C at 42 minutes and over 3000%:

97495


So I increased the RPM on my intake fans to test this and tried TM5:


97496

Curious as to why the memory temp readings were greyed out with the TM5 test since I had closed HWInfo64 before starting and reopened HWInfo64.

I think it might be fairly stable going to 1 hour with TM5. I am going to continue to test though.

Just repeated Ramtest. Getting the same thing. Temp related??

Hi Hopper,

DDR5 not much unlike DDR4 ICs is very susceptible to temperature. With the PMIC on-die, even more so. 63c is well within stock operating range, however, when overclocking it can become a problem. For my system, I simply point a 120mm fan at the modules. Ideally, you want to keep them between 30-50c for best results.

3000% coverage should be more than sufficient for a gaming system, you will probably find with active cooling this coverage will extend quite drastically.

Thanks. I suspect it is stable with TM5 going out over an hour with no errors. Appreciate your help as always. :)Â*
