post #1 of 12
Thread Starter 
Can any fellow MSI 890FXA GD70 please explain or assist how I should set CPU VDD,CPU-NB VDD voltages,must it be in line with my CPU Vcore?currently have CPU Vcore & this 2 values mentioned at 1.45v,I am looking at stable settings at 4.0GHz,thanks

Adjust CPU VDD and CPU/NB VDD first. After that, if you need higher voltages, you can adjust CPU voltage and CPU/NB Voltage

I tested with 1.40v for CPU VDD and CPU/NB VDD with CPU Vcore at 1.45v,but bsod,so I raised all 3 to 1.45v,NB is 2400@1.303,ht link is 2000@1.25v,dram is at 1.753v,rest is auto,below is my cpuz

just be careful. MSI boards use to die when you run them with OCed Thubans
For that NB @ 2400 . you need to adjust the CPU/NB VDD and /or CPU/NB Voltage not the NB voltage. Keep that on AUTO

Ok,so what voltages would be ideal for cpu nb at say nb speeds at 2600?I already replaced the mobo twice this month & not afraid to kill it again as its still under warranty:DSo its advisable to leave the other voltages other than Dram on auto?I need to run it at 4.0ghz to minimize bottleneck

I use to change CPU, CPU/NB and DRAM voltages. Rest of them I keep on AUTO.
For CPU/NB @ 2600 you should be OK with 1.25-1.30V. Try 1.25V first, if unstable bump it 1 notch at a time

It BSOD at 1.40v on CPU VDD & CPU NB & CPU at 1.45v,just set CPU VDD & CPU NB to 1.45v & its stable so far for now,does setting this voltages too high causes instabilities?Heat is no issue as temps are well within 40c

try to stabilize your CPU first( CPU/NB @ stock, Ram @ 1333, all voltages AUTO, but CPU VDD adjusted 'til CPU is stable).
CPU/NB after that, and RAM in the end
