Is it bad to run VCCSA at 1.10v?

post #1 of 6
Thread Starter 
My pc spec:

Asus Z77 Sabertooth
2600K @ 4.4ghz (1.325v)
8gb (2x4g) Kingston HyperX Beast 2133mhz ram
gtx 680
Enermax 850W DXX psu
NZXT 810 Switch


My question is: is it bad to run VCCSA (same as VCCIO on Asus Z77 Sabertooth board) at 1.10v? Cause my memory is not stable at 2133 and when I run it at 1600mhz, it was fine. So I want to run it at 2133 since that's what the ram supposed to run at. And I know al ot of ppl recommended to up the VCCIO / VCCSA to 1.10v. Any help would be appreciated.

I been running mine on 1.12V (VCCIO) for a long time now, like you i cant get 16GB of RAM stable at 2133mhz without it.
With 8GB you maybe can get it to 1.08 ?

Btw, what voltage is your RAM rated at ?

Mine is at 1.5V, it helped a little increasing it to 1.56V for stability for me.

Btw,
VCCSA should be voltage for the "system agent" and should stay at default.
VCCIO is another thing. (memory controller i think)

My ram is rated at 1.6v at 2133mhz. I alreayd put it at that, and I already used the XMP Profile too.
Yea I know the VCCSA is the System Agent, but on my Asus Z77 board, VCCSA is the same as VCCIO, and there is no VCCIO option to change the voltage. It even says VCCSA / VCCIO in the Asus Suite II Turbo EVO.

Whenever I change the VCCSA voltage, the VCCIO change to the same value.

The P67 you have is different, it does have the VCCIO option. That's why Im asking on here to see if anyone has experience on the ASus Z77 Sabertooth board. And god knows why Asus didn't put the VCCIO option in for this board.

Oh btw, how long have you been running with the VCCIO at 1.12V? And you have no problems with it right?

A bit over a year now......

Isnt there any option your missing that is VCCIO or something that can make you set VCCSA and VCCIO seperately ?

Maybe you can ask your qeustioon here:
