5930K overclocking help

Slight increases to the VCCIO (also known as VCCIN VTT on some motherboards) and the System Agent voltages should increase the stability of the IMC when running high-speed RAM. I haven't overclocked my memory higher than 2666 (I'll be honest, the RAM did that all by itself too) so I don't have any values to aim at for those two settings though.

Quite a lot of people noted that changing the VCCIO voltage wasn't too helpful for mem, as it only deals with the I/O interfaces like PCIe and the DMI connected stuff.

 

A lot of people do as much as +300mV (1.3v) on their System Agent Voltage though. Upping the VRIN (I think some boards call it VCCIN) to 1.9 (up from 1.8) should help as well.

I will try more memtest86 first, I have done 8 hours on stock settings with 1500Mhz RAM now with memtest86 without an error. I will try the overclocked settings later

So even with stock core clock my RAM speed is still 3001Mhz according to AIDA64. However CPU Z says it is 1499Mhz

CPUZ

 

 

Also my VCCIN is at 1.904V and my System Agent Voltage is at SA 1.370. These are on AUTO however that is the value to the side of it.

CPU-Z reports half the speed because it's double data rate, so that's normal. Still 3000Mhz effective

 

I think you should try give the VCCIN 1.95v and the SAV 1.4v

 

If you still have errors it might just be that your memory controllers isn't too fantastic.
