Safe Voltage (SOC/DRAM/CPU)

[m4cc45]

Hi

Not sure where to post this as it could be in a number of forums. On a Gigabyte x570 Pro what are the safe voltages?

I'm doing a little memory tweaking and about to move to the CPU (3700x) and just wondered what was considered safe nowadays?

Thanks,


M.

I can answer the ram:

You shouldn't need any more than 1.1v SOC and 1.0v VDDG. Both critical for ram stability.

Ram up to 1.45v for bdie anyway.

CPU, I'd leave stock to be fair. But up to you.

Thanks - I'll play around tonight.

RAM I'm sure is at 1.35v so that sounds like a winner to up and is BDie (Patriot Steel Series)

SOC was what I was most concerned about as I've read so many conflicting reports of 1.2v, etc.

I think it's auto set at 1.1v but will double check.

B-die safe 1.5v for 24/7 others 1.45v

Air flow over the RAM sticks ftw. Got to be careful, tell some people 1.5volts is safe 25/7 they will put 1.75-1.9 volts into the RAM.

Examples
"The actual 'damage' voltage is actually closer to 2V, JEDEC requires DDR4 tolerate spikes of 1.9V without harm." "1.55v kill hynix AFR sticks in about 10 months."

Quick wiki

Voltage1.2~1.4 V <--------
XMP 2.0 goes up to 1.5volts. 1.5V is the absolute max for Intel XMP 2.0 certifications.

Just be careful. Not all RAM are equal when it comes to voltage, Samsung B-die is being reported safe up to 1.5 volts for example (some people think even more). That does not mean that you need to run it at 1.5 volts.

I'm happy with where they are now 1.35v but was just wondering if I could push them a tiny bit more (I'm talking .1v to test). They are XMP 2.0 certified and b-die but I don't want to change them too much as I'd rather they last a while!

With samsung b-die you could push it a hell of a lot more. I am running mine at 1.45 volts but I have a lot of air flow over the sticks. 1.45 volts nets me cl15 @ DDR4-3800.

Do you mind sharing the rest of the timings?

Not the best, I just set them all to the lowest that was stable.

Of course not its fine. I run upto 1.95v+ Cl12-12-12- 4000+mhz often.

For 24-7 1.5v is fine on Samsung IC. Heat spreaders are also only for looks no cooling is needed.

Heat spreaders are only for looks. I bench 1.95-2v without any heat spreaders at all so this is totally fine. Yes remove screws pull off done.

Yeah comes off fine and rest of spreader still in place...... Oh is that 8Pack 4133mhz signature C18 I see in the box!!!

1.15V soc. Mems still have room 1.5V fine 24-7 on these dimms. You can also try tuning Procodt as you may be at the top of your cpu's cache or Imc capabilities.

Thanks for that - very helpful. It definitely gives me some tinkering to do tonight!
