My experience with the Asus PRIME X370-Pro - Page 22

post #211 of 740
The SoC voltage for the System on Chip is the voltage used to do all the normal housekeeping duties on the chip like run the chip I/O functions like memory or PCIe buses. It has helped in the past with getting memory that is not on the QVL or overclocked memory to boot and run by raising the voltage from default Auto. The biggest change in 0604 BIOS has been the big increase in default Auto voltage for SoC from 0.881V to 1.10V. Raising the SoC has been one of the proven methods by forum thread posters to get their memory running at overclocked specifications. You can safely take SoC voltage up to 1.2V supposedly.

I didn't notice any difference in case fan speeds. Every since about 0505, the case fans speed up just at the very first the BIOS is loading and then drop down. I think that fan profiles have been preserved in the BIOS updates since 0511 since I still have my custom curves loaded in the Simple BIOS screen. I think they reverted to stock from 0504 > 0505 > 0511 each time. They stuck through the 0515 and 0604 transitions.

Here for some reason the default SOC voltage is still 0.8V

I can now run my CMU64GX4M4C3000C15 at 2666 (prev only 2400) at 15,17,17,35 stock timings and 1.35v

Can't go to 2933 yet. Perhaps I need to increase de SOC to 1.1V indeed.

EDIT: Nope, neither 1.1v on the SOC or looser timings would do.

BTW: What is that new option on the RAM timings where you can choose high impedance and other impedances?

Haven't tried overclocking cpu yet. Boot drive is 840 pro. Make sure boot logo is disabled and post delay is set to 1 second for faster load up times.
Is that for a stable fully loaded system for those aggressive timings? I have the TridentZ 3600 CL16 memory and am interested in dropping my timings to your settings for an experiment. But I won't even try unless you say that is for a fully loaded production system and not just a benching experiment or can just boot into Windows.

My RAM Command Rate is now at 1T :O

What? it was at 2T until now. That is very positive IMHO considering I'm using a dual rank 4 sticks 64GB kit.

Great news. With the BIOS 0604. My G skill Flare X 3200 kit runs at the rated speed of 3200 and rated timings of 14-14-14-34. This is with a cpu overclock at 3.7Ghz, 1.202 voltage. Pretty good gaming rig! Once I get a watercooler I'll see if the 3200 ram speed still works at higher cpu speed.

That is interesting. Have you always been in Auto for Soc voltage? I wonder if the bump up was only for systems that weren't on Auto and had tried Manual or Offset voltages.

The new parameter for memory timings is ProcODT which stands for Processor On-Die Termination. It allows you to change the impedance of the memory clock lines for better matching to prevent ringing and distortions on the clocks.

I've loaded the optimized defaults before and after updating the BIOS, then tweaked all again.

Maybe the SOC stays at 1.1 if you don't. Can't tell.

RMA'd my board (and RAM), flash to 604, and now stuck on 2400.. no more 2666 frown.gif

For every BIOS update I've done so far, I always loaded optimized defaults to start at square one for the new BIOS. Same for the 0604 update. I had a 0.025V +offset added to VDDR_SoC in the previous 0515 BIOS. That put the voltage around 0.950V when loaded with my normal applications. I noticed that the Auto voltage for default memory clocks was 0.881V but it went to 0.931V in Auto for my 2933 or 3200 memory clocks. I think it might be tied to memory clocks when overclocking. So in my case the Auto voltage really did increase when starting from optimized defaults.
