Z370 vs z390 9900k CPU temp differance SOLVED

I thought I would give a shout out in regards to my experience upgrading from an 8700 k two a 9900 k. While staying on a z370 bord. At first I experienced extreme CPU temperatures even with it 360 all in one cooler. Even at stock clock speeds the CPU was throttling and hitting over 95c.

 

NOT TO WORRY 

 

After nearly pulling on my hair out and almost going to my local Memory Express to upgrade to a z390 motherboard I took one last stab at it and realize there was a newer bios update which team to solve everything. I'm now sitting at a comfortable 77 two 79c when stress testing with prime with a over clock of 5.0 in all cores at 1.33v

 

My exact board is a msi z370 sli plus.

 

So to anyone out there that is having trouble controlling there temps on a z370 check for a newer bios version as that is  what fixed mine. 

 

Good luck and may your temps be low.

 

Cheers

but the reason for swapping boards like that is usually for VRM temperatures...

I agree it's usually due to vrm temperatures, not only was I throttling due to CPU TJMAX, the  vrms were also throttling down due to a toasty 110c at stock clock speeds even at 1.29 volts.

 

Once I updated the bios to the newest version, vrms with my overclock of 5.0ghz dont exceed 60c.

 

Theres aperintly been two new bios releases for my board since the upgrade which allowed the 9900k to be used on the board. I was originally using that version.

 

Msi for some reason has had weird bios versions that spiked temps  even some older ones when I was still using the 8700k there was widespread complaints about overclocks no longer working due to stupid temp spikes on certain bios versions...

 

So if u have a msi board even if using a 8700k try different bios versions and even Google it to see which ones people found to be best.

Not sure what the long term consequences may be of running an 9900K on such board... I'd be skeptical.

Thankyou for your posting this . I have same board And love it to bits . I’ve got i7 8700k and going to pickup a 9900k on reading your post . I have noticed msi bios make hell of a difference as do asus bios too . They use really good capacitors and strong vrms on the sli plus , infact I believe there better than the z390 tomahawk vrms although I maybe wrong there all best Thankyou again
