i3 6100 Can Only Handle Up To 2666Mhz Ram??

Hey Guys,

 

I run my i3 6100 at 4.5Ghz (1.375v) (BLCK method) and my Crucial Ballistix (rated at 2400Mhz) at 2595Mhz (1.25v) on a Asrock Z170 Pro4 motherboard. I wanted to overclock my ram further as an i3 really benefits from it, but my system then became unstable. I assumed this instability came from the fact that my ram was only rated at 2400Mhz, and it couldn't overclock any further.

 

Standing by this assumption, I went out and bought 16GB of Corsair Vengeance rated at 3000Mhz (1.35v)

Problem is, I still can't take my ram past 2666Mhz, even with the new Vengeance sticks rated at 3000mhz. 

 

I went around and did some searching online and discovered my motherboard can handle up to 3866+mhz ram (wtf who needs that). I also read about IMC (Internal Memory Controllers) in Skylake chips.

I am now at the conclusion that I got really unlucky and got an i3 with a bad IMC. (Can only handle up to 2666Mhz)

I know Skylake is only officially listed to handle up to 2133mhz, but i've never heard of anyone being stuck at 2666 max before...

 

Am I screwed until I get an i5/i7? Or is there anything I can try to make this work.

All replies are appreciated!

 

Cheers!

 

UPDATE #1

At stock speeds, (3.7Ghz) I can discovered I can run the ram at around 2800Mhz max. But when I try to run the same speed at 4.5Ghz I don't even POST. 

 

Maybe this info is helpful?

so on your budget build, you went out and bought new memory instead of just slapping an i5 in there? 

 

not qualified to answer the question, however. Sorry.

Yeah, i'm getting a burst of money for Christmas so i'll be able to get a new processor then. I just sold some old hardware and didn't have anything else to buy. I figured if i was going to get a new processor and case then I might as well get some nice new (and sexy asf) ram to go with it. (Had only one stick of 8gb before)

 

EDIT: 

The ram was on sale for £89, which is a killer deal for 3000Mhz VengeanceLED. (even the 2666 version cost more lol)

Base clock overclocking is a very unstable way of, well overclocking. Better off with a 6600k

I got some Vengeance, can't get it to run at 3000 on an Asus board, but it does on an MSI one. Could be interaction between mobo and ram... I'm not up to speed on bus overclock i3, but is that limited to certain BIOSes? I find the ram compatibility is often updated in newer bios...

You may be right, but i've seen Digital Foundry and countless others get an i3 running perfectly stable with 3000+Mhz...

Have you checked if your Asus board supports 3000Mhz ram? It's not just up to the CPU when it comes to handling ram.

The ram is rated at 3000Mhz. Even the Ram's XMP profile sets it to 3000Mhz.

Yes, I've had G.Skill Ripjaws 4 running in the Asus at 3333. There's something about Vengeance it doesn't like and it'll only boot with it at 2900, but the ram doesn't appear to be faulty since it runs at 3000 in another MSI board I have. And I have also swapped CPUs between them too. I think this is just one of those compatibility things.

Fair enough man, atleast you can get 2900Mhz... xD:(

 

EDIT:

I don't think it's the ram being faulty or a compatibility issue... Honestly it feels like I haven't even changed ram. (other than the addition of the sexy asf LEDs)

I think it's a problem with the BCLK OC method (I can't get mine to run past 2666Mhz either)

Possibly. But I tried running it at 3000Mhz (Default XMP profile) even without overclocking and it still wouldn't boot...

How do you like that board?  I'm about to build my son a rig for Christmas with that exact board and an i3 6100.  I got some cheap Geil DDR4 3000 that I'm going to be using with it.  Hopefully I don't run into the same problem.

The board is incredible for the price, and I like it a lot. The only downside is this ram issue i'm dealing with.

Great.  Thanks for the feedback.

 

Speaking of price, I'm picking it up brand new for $39.99 at Micro Center.  The i3 6100 just went on sale for $99.99 so this is working out perfectly.

Woah $39.99? I payed around £90 for mine haha. That's a mad deal!

Yeah, it's $94.99, but Micro Center gives you a $30 discount if you buy the CPU there as well.  Then ASRock is giving a $25 rebate on top of that.  I have no problems with buying the CPU there as they usually have the cheapest CPUs out there.  I'm still torn between the i3 6100 and a i5 6600k, but he's only 7 so I don't think he needs that much power yet.  I was just glad to find a Z170 board that cheap so it can be overclocked in the future with or without an upgraded chip.

 

Have you tried increasing VCCSA voltage along with DRAM voltage to get the RAM to boot at 3000 MHz?

Not so sure about the VCCSA voltage but the ram is definitely running with 1.35v

Give your VCCSA a slight bump.  It may be an offset voltage so try something small like .01v to .02v at first.  Set your DDR to 1.4v and see if that combo lets you POST or boot with XMP set.  If not, we can play around with manual timings to try to get you running at the speed you're wanting.

Cheers, I'll try giving my VCCSA a small boost but i'm not too sure about setting the ram to 1.4. Isn't 1.35 the maximum safe voltage for Skylake?

It's completely fine at 1.4v.  We're just trying to see if you can get it to POST/boot.  Also, does your board support eventual voltage?
