I7 6700 (locked) Overheating

[FilipGT3]

Hello,

A few days ago my cpu started hitting really high temperatures while gaming (around 95 degrees C). Prior to that my pc just crashed with a grey screen and sent out a loud buzzing noise through my headset. A few months ago my cpu was fine and never got very far above 80. Linus said in an old ncix techtips video that running a skylake cpu with ddr3 and not ddr3l could be harmful to your cpu. Could that be it?

 

I honestly have no idea why this is happening and i'm getting a coolermaster 212X for my cpu, but im not sure if my cpu's temps will keep rising. Please help. Thanks in advance. : )

Are you running DDR3 memory with your skylake CPU? If so then yes because DDR3 requires much more voltage than DDR4 and it is frying your chip.

DDR3 is harmful for skylake

Thanks for your quick reply.

Technically, DDR3L is fine for Skylake but I wouldn't even try it honestly. DDR3 is bad, yes. But before panicking and thinking your CPU is frying, check the thermal paste, and also, note that it could possibly be the crappy TIM inside the CPU that just degrades/moves over time, or was simply applied incorrectly. I recently RMAed my i7 4790k because one core was getting ridiculously hot (95°C) while the others were around 80°C (still high with a Dark Rock 3). It most certainly was a problem with badly applied TIM in the processing chain. The new one they sent me never goes above 75°C even at full load.

 

Since we're talking about all this Skylake + DDR3 voltage problem, I've always wondered why some vendors like Gigabyte are selling DDR3/DDR3L compatible motherboard with a Skylake socket. I've always wanted to know if those motherboard were specifically designed to protect the CPU from the higher voltage required by DDR3 RAM or if it's just a bad idea to buy one of these...

Just get DDR4 and be safe

I don't care, I don't want to change  It's just a general thinking on why those boards exist if they can't prevent damage to the CPU

No,i'm talking if your building a PC go with a DDR4 motherboard and ram if your choosing skylake just to be safe since DDR3 has issues with skylake

 

If you already have 1150 there's no reason to change

You 3, read this topic from this post onward and tell me why your statements about DDR3 + Skylake = barbecue are wrong.

@FilipGT3, I would try remounting the CPU and perhaps giving it a good clean while you are at it. Even if your voltages are messed up, DDR3 shouldn't be causing a 15C temp spike.

I have a name

 

I don't say its a barbecue,i say its a shitty idea to put DDR3 with Skylake

While I agree that it's not wise to get Skylake and DDR3, that's not what you said. At all. As per your quote, you stated "DDR3 is harmful for skylake", which is simply not true.

The default voltage of DDR4 is 1.2V. You might recall that one of the benefits of the DDR4 memory standard is the increased power efficiency. This also means that the memory controller designed for such a standard will naturally be able to tolerate less extreme voltages. DDR3 memory on the other hand is actually 1.5Vs. Now the primary problem is that Intel has officially listed support for DDR3L standard, not DDR3, which actually has a voltage of 1.35V. And it is DDR3L, which is supported with Skylake.

And that's why I'm telling you to read that topic. You are just copy pasting what you've heard from someone else, without actually understanding what's going on. No idea where you got that phrase from, but it's incorrect info right there.

 

So please, do what I asked and do some reading. If you do, you yourself will realize what's wrong here.

I read it,i understand it,it will work but you don't understand me,there's things that can go wrong,the guy literally said you NEED to be careful with DDR3 maybe the OP was not?

That's fine then. We're all allowed to make mistakes. Now that you've learned, though, don't spread wrong info anymore and work to correct those that do.

Perhaps. Still, if his CPU was going bad, I would expect an abrute failure rather than a 15C jump in temps. It's more likely for the cause to be an external factor, whatever it might be, rather than DDR3 burning everything.

Thanks...you're on of the nicer ones here...:)

Just an update:

I think i'm going to buy a new motherboard and ram just to be safe. Thanks for the replies.
