Safe RAM Voltage

[Puerto_Rico]

I have Corsair Vengeance LPX 3200 on my B350 Tomahawk. I'd like to know how far can I go with RAM voltage for daily use?

I think that anything below 1.4v is okay. I have 1.36v on 3000mhz sticks that barely boot with 2900mhz lol.. 

What kinds of voltages do you have in mind?

I was thinking max 1.4, but I don't know if that would be safe for 24/7

Rule of thumb is don't subject the part to more than 10% of its rated voltage. All increased voltage does to semiconductors is increase the current that passes through them, which can cause more heat. But RAM is pretty low power as is so it's not really a problem. Plus they all have these fancy heat spreaders anyway.

Meh, it's fine. Provided that you have some sort of airflow over RAM sticks and that they have some kind of heatsink on them..

It's fine. But idk why you'd run so high anyways..? Since most of them come at 1.26v or 1.32v out of the box. I bumped my voltage because they would write errors at lower voltage. In other words, my RAM is bad. But if you have any sort of good sticks, you don't really need high voltages. correct me if I'm wrong

With overclocking ram it's basically the same as OCing a cpu, more speed you may need more voltage, ram just has the extra of timings that you have to work with

at what voltage are you running your 7700k?

I forget... 1.3something, nothing crazy.   Checking cpu-z it says 1.34v

[PETRGangKing]

I've got mine running @ 1.45v

yeah, but you're running at 5.1ghz
that's understandable.
My 6700k does 4.7ghz @1.315v, but 4.8 @ like 1.4v.. It's just goes to hell above 4.7

skylake is supposed to be a good overclocker if you can get it above 4.6 right? If I delidded mine, It get around 10-15C headroom and would definetely push for higher voltages, but I can't cool it, even on water. TIM is just crap

Oh no, my RAM is @ 1.45v. My CPU is @ 1.38v. My experience with skylake was similar, I was at 4.8ghz@ 1.28v but I had to go up over 1.4v to hit 4.9 so I left it at 4.8ghz. I had to have my kaby lake delidded, stock thermals were trash. I just sent it to sillicon lottery, and it helped significantly. I was getting 80 degrees under load @ stock voltage, now my max temp under load is 64 degrees and it averages about 54 degrees.

That's insane.. Because mine runs in mid 70s with a 4.7ghz overclock on liquid, and 4 fans on 240mm rad. So.. and that is with a really good thermal paste. the best I've found.  8.5 W/(m·K), which is like insane for a themal paste.. and it helped a lot compared to stock thermal paste. upwards of 7C. but if the IHS has crap TIM beneath, then it's all for nothing. I'm not that brave to delid it without a proper kit, so I'm stuck where I am. My next CPU Will be a high performance 6/8 core.. 4 cores is just shit if you want anything beside gaming.

Silicon lottery will delid for $40 plus shipping. They do good work. I'm going to buy my 8700k from them,binned and delidded.

I'm from europe.. And they sell binned CPUs for much more..

if i lived in germany, then maybe i'd be able to get my hands on one. But I'm from Slovenia, and here the supply is outright shit

Ah yeah they charge a premium here for binned, but from what I've seen people pay more for stock chips in some countries

yeah.. I expect an 8700k to go for 450eur here or cca 500USD

Shit , I would hate to see what my i9 build would run out there .

here's an example. 6900k is around 1400eur (1540USD) and 6950X is 2300eur (2530USD)

 

Oh, did I mention that money is mush more easily obtainable in USA? here, a very good salary is around 24k a year. anything above that and you're considered rich. lol

$24,000 here is nothing. I couldnt even pay my personal bills off of that.
