Correct, from 2 sticks at 6GHz, I need to lower to 4.4GHz to get 4 sticks stable.
I have tried all the suggested voltages for big OC and 4.8GHz became a little bit more stable but it isn't 100% stable so I reverted back to 4.4GHz.
at the end I was able to run 6000MHz no problem on my 2x16GB Samsung Corsair Dominator 5600MHz C36 using XMP and no other settings changed apart the ram frequency.
if I add two sticks more I goes down from 6GHz to 4.4GHz since I can't get 4.8GHz stable with 4 sticks.
How this can be possible...
Those are all my settings.
Basically the voltages that worry me are
CPU Core/Cache Voltage [Adaptive Mode] - > Additional Turbo Mode CPU Core Voltage [1.36000]
Memory Controller Voltage [1.25000]
DRAM VDDQ Voltage [1.35000]
DRAM VDD Voltage [1.35000]
DRAM VDDQ Voltage [1.35000]
DRAM VDDQ TX...
DDR5 is full of false advertisement, bad marketing and a lot of missunderstandings.
This is the reality of the current situation.
There is no single rank 32GB DDR5 modules currently.
This means that if you want 64GB of DDR5 memory you have two options.
Get a 2x32GB dual rank modules.
but is it safe to run "CPU System Agent Voltage" to 1.25V?
My Asus mobo shows values greater than 1.2V with a warning.
same for the Memory Controller voltage, everything over 1.2 in in yellow (means warning)
12900K, reaseated everything,
if I put things on A slots sometimes does not go over 4GHz and sometimes does not boot. I have seen similar problems with other asus boards...
done, it doesn't helped. I'm pretty worried that I have a faulty motherboard.
I have tried with another kit also.
I have 2 banks of Patriot 4800MHz C40, even with the two patriot I have the same problem.
this is my default bios settings.
If I manually set the frequency to 5200MHz I can boot but CPUZ always shows 2000MHz.
Isn't a DDR at 2000MHz operating at 4GHz?
If yes why?
I see 2001 MHz in CPU with default bios settings and by manually setting 5200MHz, why?
at the end I discovered why my OC is unstable.
after an entire day passed benching and trying I found the coulprit.
CSTATES makes my OC completely unstable when using AVX256 with Prime95.
Using sync all cores 5.1/4.0 with AVX offset 5 and OCTVB +2.
those are my settings:
even if CSTATES is...
my 12900K reaches 85°C during rendering at 22°C ambient temp.
During summer ambient temp can go up to 32°C this means that my CPU should hipotetically reach 95°C during rendering.
Will I damage my CPU by rendering in summer?
I have 4K euros of components getting the dust because there is no DDR5 in the entire europe.
My "refund window" is expired and I can't even ask for a refund.
Shops here says that there will be no DDR5 for months, a lot of months.
I have spent a lot of money for the components and I will not...
is there someone who have experience of Corsair HX1200i PSU?
Is it good enough for a single GPU system?
What about quality and reliability?
I will use it with a 3080ti and a 12900k OC.
I know that 1200w is too much for that system but hx1200i is the only one I have available now.
