will my Skylake CPU die with DDR3?

[arnavvr]

I've been running it for around 8 hours a week for the past 6 months or so, sometimes even more than 8 hours a week. I haven't seen any ram degradation, the clocks I'm able to achieve haven't changed at the voltage I run.

Normally I run 2.1-2.15 for 2800 to 2860 9-12-12-17.

Need about 2.3 for 2933 c9

 

Why don't you have EK Monarch Blocks?

[arnavvr]

You have a skylake CPU?

I thought you only had the 4790k thats in your sig

 

He has a 4790K, but the same applies w/ Skylake. Extra Volts aren't going to instantly going to kill your CPU.

continuously 24/7 for daily use?

 

or for a couple minutes to see what the highest overclock possible he could get was?

 

obviously you dont know the difference do you...

Highest DDR4 speeds i have seen being ran 24/7 is 1.65v on Skylake, 1.7v on X99. What I said earlier, about people running 2.1V, they were using 1.3v VCCIO/SA voltages, and are no way considered safe to run 24/7. At 1.65v, you can technically get away with 1.2v VCCIO/SA, as long as tertiary timings are properly taken care of. I personally run 1.4v, because that is the same voltage those 4266mhz kits use, and under load, 1.4v = 1.44v. 1.35 = 1.39v, etc. So always anticipate slightly more voltage under load.

 

The overclockers i mentioned before also use very exotic cooling solution on their kits (With the exception of Alex@Ro, who lists different IC's and their ability to run fine on air at certain voltages). 

 

Seriously, take the time and go through these pages: http://forum.hwbot.org/forumdisplay.php?f=120

 

What people do with their ram is quite amazing to be honest.

when i get my skylake board ill run my ddr4 at 1.5v for normal use just to prove that nothing happens

We're talking about Skylake. Not Haswell. Unless they're using the same IMC, Haswell is irrelevant to this discussion when discussing the allowable voltages for DIMMs. But seeing as how Haswell does not support DDR4, I would say they're using different IMCs.

no i have some tg xtreem 3866c18 that will run 3950c12-18-18

I can do that right now. In fact, i can do 1.65v (DDR3 overclocked voltage) just to prove it wont cause damage, if people want me to. Pretty sure i could break 3800mhz with that, lol.

i never said anything about using DDR3 with higher voltage killing your CPU

where the hell did you get that from

 

and yes more voltage shortens the life span significantly

and yes, too much voltage can kill ANYTHING instantly

go ahead and put 10v though your CPU if you dont believe me

[MageTank]

I wish. If i was, i wouldn't be struggling to pass 3200mhz CL15, lol. I must say though, this $46 Panram kit (2133 CL13) has come a very long way considering what it is.

That's excessive. DDR3 won't shorten the lifespan of Skylake. You don't think ASUS did R&D before they rated their DDR3 boards at 1.65V?

it depends on the memory ic's as to how much voltage you can put through them.

that is a good improvement. you should join we could help you make your system much faster.

I am not that hardcore though. My system is going to be stuffed into a sub 4L box, and heat constraints will be very real. I wouldn't mind learning more about timings though (Kinda stumbling through them as i go, figuring out which ones impact performance, which ones impact stability, etc) and I certainly would not mind figuring out how to pass this 6600T's very steep voltage wall at 170 BCLK. Seriously, after 70%, i cannot boot. 170.1 fails, lol. Thermals are fine in my ITX case (72C after 48k FFT prime95 for 15 minutes, due to non-K's losing AVX after overclocking, nerfing FMA3 in the process).

Do you still have your G3258 PC? If so, make that your secondary benching PC.

they dont make intel CPUs do they

Holy shit, man. 70% overclock???

Damn, son. K series skylake must overclock like monsters!

I have a couple spare PC's. Even got a G4400 that does 4.75ghz on stock cooler. Might pick up a board for it to run it 24/7 with my current Panram kit after i get me a 2x16gb kit for my ITX build. That way, i can run 512-4096FFT Prime95 24/7 on it to stress the IMC at 1.65 vDIMM. If a year of that does not kill the IMC or degrade it, nothing will.

you dont have to be in the extreme league there are leagues for novice and rookie that you would be in first. also you dont have to be on ln2 to jion in everyone start with air or water cooling, even the top guys and you can ask them stuff and learn a lot about your system and get good performance gains.

That 70% is by no means stable. My 60% OC is stable at 1.3v, both CPU and ram. At 170 BCLK, it takes 1.39V to even boot into it, and 170.1 is immediate no-POST. I am pretty sure it will take more PCH and VCC PLL voltage to make 70% stable. Sadly, the old "+10% stock" rule does not seem to be working, as i have yet to find a way to stabilize it. I managed to make 166.7 stable (4.5ghz) at 1.35V, i just don't really care to run that high (Again, sub 4L ITX case soon, need to make sure heat and power draw is within reason).

60% is still crazy impressive.

most locked skylake cpu's are capable of very high% overclocks as they are slow to start with. its like the pentium E2160 can do over 100% overclock with ease, because the stock speed is 1.8ghz

Exactly. The one thing i will attest to, and it might just be a fluke or one time occurrence, but the T series seems to be highly binned when it comes to having very low voltage leaking. I love this chip, and it will work perfectly for ITX. Part of me is kicking myself for not getting a 6700, but i got this 6600T for $200, and I honestly do not see me using HT, let alone being able to deal with the extra 10C of heat that typically comes with it.
