will my Skylake CPU die with DDR3?

[Jumper118]

And the Core 2 Duo E6300, stock 1.86GHz

well yes any cpu under 2.5ghz really.

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.

the t series is kind of like buying a xeon, low power cpu's do tend to oc well because like you said, the stock voltage are chosen because they are lower.

I feel like the people know what they doing and stuff will buy the locked while those dont will buy K and then spreading misinformation

People will still recommended K over non-k. Yeah I would get that 6700 instead of K and let me see you kicking in regret.

this is 10000% correct a lot of ppl on here are noobs and often give bad advice.

There are some caveats with non-K overclocking though. Just look at my pictures a few posts back. See how bad my L1 cache performance dropped once i overclocked? It's not just me. It happened to you, and a couple people on both MSI and ASRock forums. We lose access to AVX instruction sets, C-States, iGPU's, etc. I would not judge anyone for buying a K series CPU, not would i feel they would regret doing so.

 

Non-K overclocking offers only one advantage over K overclocking, and that is Price:Performance. To put it simply, you pay for convenience when buying a K CPU over a non-K CPU when it comes to skylake overclocking. It is much easier to change a multiplier, than it is to research for a proper non-K overclocking board, getting a SkyOC bios,  change BCLK, adjust ram within specified parameters, etc. 

 

I mostly see this non-K OCing happening on budget i3's and i5's. If you have the cash to invest in an i7, the difference between the 6700 and 6700k MSRP is only about $40. I would personally pay $40 to keep my L1 cache speeds and C states.

Yes, but the Intel Xeon E3-1230 V5 is $120 cheaper than i7 6700K.

that is correct, however they will bring features back in future bios updates

[MageTank]

Yes, but the Intel Xeon E3-1230 V5 is $120 cheaper than i7 6700K.

But it does not work in Z170 boards, and I have yet to see a C230 series board that can OC these Xeons.

Do you have a source for this information? I have been trying to get answers from ASRock support for over a week regarding L1 cache speed, and all I got was a moderator on their forum that tried to help, but ultimately did not know how to solve the issue. Seeing as both MSI and ASRock suffer the exact same L1 cache problem, I doubt it is something that can easily be fixed with the bios. If anything, a microcode update from Intel will be required, and I doubt they care enough to do this. 

 

It's not that I don't believe you, I just can't find such information myself.

there is no info but it is a logical step for them to take. the main reason why you dont have those features is because extreme overclockers have pushed the development of this and now that its working ok most of them havent bothered getting other features working.

well sometimes the trade-off has to be made in order to achieve what we want.

But even though our L1 got reduced, but for gaming and normal use it would be fine, it wont affect anything much. 

For some app maybe suffer a lil amount of delay, but I dont think it will be noticable.

dont know if it can be fix by coding it, since i can probably mess thing up. Yeah and I did notice the different between my 2 system L1. BUt normal usage I dont think it will be a problem

I know how it feels man. I usually ignore those topics/threads.

You have a skylake CPU?

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

What I'm trying to say is, running ridiculously out of spec on one CPU vs another should show similar results.

If my IMC was going to degrade, it would of done it already and I would of had to loosen timings, and possibly add more system agent voltages. None of these things have happened, even after hundreds of hours of running ram nearly 1v higher than is considered "safe'

but the 4790k was only released a year ago...

you wouldnt notice any degradation in such a short period of time...

Bingo! Which is why people saying "DDR3 on Skylake will cause degradation" is unfounded, because it has not been out long enough to test this. Even in the initial report from Intel, their wording gives it away for me. "Usage of DDR3 at default voltages can damage Skylake". Voltages. Plural. More than one. Clearly they are not talking solely about vDIMM. They clearly mean more than one voltage, and i suspect they are referring to the VCCIO/SA voltages, which is where the real damage comes from. 

 

One could try to argue that they meant 1.5 and 1.65 vDIMM, but 1.65 vDIMM is not a default voltage. It is not supported by JEDEC at all, and thus, does not make sense to be labeled a default voltage. 

 

Remember people, Intel only "officially" supports 1600mhz 1.5v memory on Haswell. Anything above that is not officially supported, and yet people have been running 1.65v now for years. 

 

Yes, i know. "You cant compare Skylake to Haswell, they are two different things!". Very correct. However, I can compare Intel to themselves, as they make these "official support" statements every single time a product is released. And as overclockers, we have ignored these "official support" statements every single time. 

 

I know Intel is a much greater source than I, as I am just a random nobody on an internet forum. Which is why I will not try to force my views on you, but i can at least try to give my experience on the subject, as I have yet to fry any of my IMC's running outside of Intel's specs (both on my Haswell rigs, and on my current 2 Skylake chips). I'll even buy a Skylake DDR3 board and run 1.65v DDR3 and test this. By the time i can get conclusive results, it won't matter though. A new chip will be released, new statements will be made, and trying to use my previous evidence as a comparison will be met with the same response as we've seen in this thread. "You can't compare the two, they are entirely different architectures". But for the sake of science, i'll still gladly do that test.

[SeaW0lf]

I know this thread is a bit old, but I am discussing about the same topic and this thread has good information.

 

I have seen a Skylake overclocking guide and it says both VCCIO and VCCSA should tops at 1.35v. 

 

Then: how high does DDR3 1.65v memory runs on these values (VCCIO / VCCSA) for Skylake?

 

Do you need to manually lower the values to stay below 1.35v? If so, does this compromises performance / timings / clock?

 

These are simple questions that I cannot find anywhere.  Note: Google can be a little bit tricky / elusive sometimes.

 

I appreciate any info.

Cheers,

 

Obs: I am not going to buy DDR3 memory, I am just trying to understand the limitations of DDR3 with Skylake.
