Is DDR4 3000 MHz RAM leading to crashes even with a successful processor overclock?
Is DDR4 3000 MHz RAM leading to crashes even with a successful processor overclock?
To ensure the lifespan of his CPU, he is focusing on overclocking the memory controller. I'm just trying to assist him, even if he doesn't want to hear what I'm saying. I wasn't talking to you until you did. Just a heads up, I've been using 5Ghz with every CPU I've had—2500K, 2550K, 2700K, and now 3770K—and I'm really lucky!
Your XMP settings are 15,17,17,35 @ 1.35v
You might run the memory manually at 1.20v, but Corsair’s timings at this speed are inconsistent; it’s best to test each listed timing separately to find the most stable option for 1.20v DDR4 slot voltage.
1 = 16,18,18,35
2 = 15,17,17,35
3 = 14,16,16,31
4 = 13,15,15,28
1 represents the loosest to 4 the tightest; begin with 1 and evaluate each timing at your standard CPU configuration to identify stable results at 1.20v.
You need to turn off the XMP profile and manually apply these settings in your BIOS.
After confirming reliable memory timings, you can gradually increase the CPU multiplier and voltage to support higher performance, checking stability at each step.
Progressing overclocking one stage at a time is advised, testing until you hit the CPU’s maximum clock speed that your cooling solution can sustain.
You’ll eventually hit a limit based on available cooling capacity—beyond that, further increases won’t be possible.
Also, would lowering your RAM voltage help maintain the CPU voltage in manual mode? I’ve noticed that even when I set it to boot, software shows much higher voltages (sometimes 1.4v), and at stock speeds it can actually drop to 1.4v or less. I’d prefer a lower reading, especially since Skylake isn’t designed for such high running currents at normal clocks.
Cheers

So, FYI I've been running 5Ghz with every CPU I've owned 2500K, 2550K, 2700K, and presently my 3770K, so I must be really lucky!
lol
As a matter of fact, yes. You should have won last night's $1.5 billion Powerball jackpot.
I've had a 2500K, 3770K, 4690K, and now 6600K, and only the 2500K was able to run at 4.9GHz. It was able to boot at 5GHz, but would crash when anything more than CPU-Z was loaded. I miss that thing.
Since you're so 5GHz-savvy ... what would you use for settings to get a liquid-cooled Skylake to that speed?
Edit: Are you recommending that Matthew try running the RAM at 3000 with 1.2v? You mention timings, but not speed.
MatthewScott :
Setting my RAM to operate at a lower voltage might help maintain the CPU voltage in manual mode as intended. I’ve noticed that regardless of what I configure in BIOS for booting, the software still shows much higher voltages. Even at standard clock speeds, it sometimes reads 1.4v or more. I’d prefer to see a significantly lower reading, since I’ve heard Skylake isn’t designed to handle such high currents at stock frequencies.
Cheers
CPU voltage in true manual depends on BIOS settings, not memory voltage.
You’re just starting with overclocking—please invest more time in learning and building solid knowledge.
Are you suggesting Matthew try running the RAM at 3000 with 1.2v? You reference timings but not speed.
That's a good catch!
2133mhz, I should add that back in. Thanks.
I thought he'd picked it up from the Intel Design Specs I shared, but sorry for the oversight.
I've configured my RAM to auto, synced all CPU cores to 4.2, and adjusted the voltage to 1.2v to observe the results. It's stable... But...

I remember you used to be a Community Reporter for Toms, you haven't been posting for quite some time?
What's Up?
Yeah I was a Community Reporter for a minute there. I took an extended break from overclocking in general and forums in particular, because overclocking wasn't fun any more due to Intel doing the FIVR thing. I started and finished a two-year degree in networking, got myself a full time job in networking, and concentrated what little free time I had in having a social life and doing some gaming. I'm better at time management now, and there is some hope for overclocking with Skylake and possibly future generations, so I decided to come back and see what's what.
Edit 1: Matthew, don't put any stock in that reading. Mine's low by 0.15v in that screen. I don't think I've ever seen it correct.
Edit 2: I tried your "secret sauce" memory underclocking thing, Ryan. It did absolutely nothing for me -- still required the same Vcore and still rebooted itself testing 4.7GHz at 1.4v. I knew before I started that cooling wasn't my CPU's limitation (I have 2 360 rads cooling 1 CPU and 1 GPU) but I figured what the hell. It would probably help somebody with less extreme cooling though.

I was a moderator when you were a Community Reporter, and I gave that up as well.
I'm glad you're back we need more members that actually know what they are doing, we are flooded with first time overclockers trying to overclock hardware that when it was bought was not the best hardware for overclocking.
The first part of overclocking is gaining the knowledge and then buying the hardware that will get them there and then using the knowledge to reach their overclock goals.
Too many today want you to give them their exact overclock settings so they can be on their way, wham bam, thank you mam!
They do not want to invest their time learning overclocking and without that they have no foundation.
The reason I wrote 2 overclocking guides one AMD and one Intel was so they could help themselves, but as simple as I wrote them they were still hard to grasp for some with an absolute zero understanding of bios setting terminology, and some didn't even know how to access the bios.
I had considered to creating a thread called Bios 101, and began studying in that area and it would have been a fairly straight forward thing to do, if all the motherboard manufacturers used common bios terminology, but they don't.
Then new platforms bring new bios terminology and the soup pot is even fuller, I know you understand that.
Regarding Edit 2: A couple of us have experimented with the secret sauce and discovered the higher the overclock approaching 5ghz and beyond the better it works.
And actually I have not been lucky with the CPU lottery, I have been cooling with below ambient chilled water cooling, and that cooling has allowed the 5ghz overclocks, as my coolant temperature is usually 15c below ambient room temperature.
If you are curious it is stickied at the top of the overclocking section.
