Memory Speed

30 posts in this topic

I am looking over system specs using CPU-Z, I just installed it.

 

I am looking to do a few upgrades, and memory is one of the options.

I was pretty sure I bought 16Ghz 1600Mhz RAM, so I thought CPU-Z would tell me exactly what it was, and its showing the DRAM Frequency at 667.9Mhz.....

 

Is my memory set wrong, or what's going on? The only other thing I see is NB Frequency which is 3906.7Mhz which looks more like my CPU speed...

Just shut down your computer and physically look at the sticker on the RAM. You might have them set wrong in BIOS also.

multiply by 2 since it is DDR. But yeah, it is either DDR3 1333 or it is set wrong. Your motherboard may support 1333 timing by default and you need to manually set the timing to 1600.

Ah, that does sound more correct, 1333mhz.

 

I probably know the answer, but would an upgrade to 2400Mhz RAM make any difference.

Also, my motherboard says up to 16GB (only has two slots). Is this because only 16GB comes in two, like are there not 32GB in two sticks? Or is this just a limitation on the motherboard itself?

The RAM slots have a limit of how much RAM they can handle, across one up to 4 sticks together. 16GB is your ultimate level.. If you go above that, you will start having issues.

Mine is different to but go onto SPD tab youll see XMP-1600, below that 800Mhz so multiply it by 2 and that's ya ram speed, just installed it have a look and looks right. I think the NB frequency might be North Bridge frequency. also maybe the DRAM timing lowers when its not being used a lot to conserve power then when it gets stressed it clocks upto 1600mhz... I dunno maybe someat like that

Well you can buy 16GB server modules (ECC Ram), but I dunno if they make consumer ram in that size. In any case, it probably has something to do with the memory controller design. All of the 4 slot consumer motherboards I've ever seen only work with 32GB total (8 per slot). There's no real inherit architectural reason why this would be the case though. But, If the motherboard says it only supports 16, then it only supports 16. They wouldn't arbitrarily limit something like that. Memory controller configuration for DIMMs can be pretty nuanced depending on the design (this slot must be filled, this slot must have the smaller amount of memory, etc).

 

I wouldn't go and buy DDR3 2400. It's unlikely that you'd notice a memory bottleneck (or difference) in real world usage patterns.

 

EDIT: also are you actually using the 16GB anyway such that it would matter if you had 32. I don't find that I ever do even when running VMs and such.

Alright, last question, not sure if anyone would be able to answer.

 

I love my ITX system, will not be going back, even with the limitations. But, anyone have an idea when (if ever) they will be getting more RAM slots. Or is more RAM slots only ever going to be on Micro ITX (or whatever the size above is?)

 

And if I was not clear, I have a Mini-ITX system.

dunno but if all your doing is gaming and nothing like sound editing video editing and all that jazz 16GB is more than enough tbh. The ram slots will be limited by the boards size. you can only fit so much onto a form factor and if its only got room for 2 then that's all there will even be :d

Wont really make a difference but odds are you are running in 1333 which is either max of your mobo or just a limitation. If it supported more in it's current configuration it would automatically do it.

As mentioned though, 1300 vs 1600 is only a small difference on benchmarks, nothing nobody in the real world will notice :p

Yeah, no-one is going to know for sure, but it is unlikely. That being said, I googled briefly and there are evidently some 2 slot itx motherboards that support 16GB Dimms so that probably would do it for you.

Did some upgrades,

 

I picked up new mobo, to have more RAM (but I have more reasons then just that).

 

I picked up 1600Mhz ram be mistake, my current 16GB is 1333mhz......they are both G.SKILLS, will they still work together? Will the 1600 just be down clocked to 1333?

It'll clock down or you'll need to manually set the timings. Unless somehow your motherboard is super finicky and badly designed.

It's an ROG series, so I'd hope not lol

 

Thanks.

Yeah, lol, I haven't see any in ages with issues like that, but I never rule out possibilities. You never know how design can go wrong for little tested aspects of a system :-D

So after actually setting up my new system, there is indeed an issue.

 

I bought 1600Mhz RAM by mistake this time, and we thought the RAM I already had was 1333Mhz. That is wrong, it's actually 1866Mhz.

 

But, now that both are plugged in, the UEFI is showing them are 1333Mhz.

 

What's with that? Anyone know how to change these settings in the GENE UEFI ROG setup?

Is there no XMP profile configuration in the bios?

I have no idea what that is :)

 

It's stock though, no settings changed.

Yup, that was it. I find that weird, but it's working as it should now.

No problem, many boards do default to 1333 (it's a common issue, I'd say). As for the configuration settings, a little odd, but then most bios utilities aren't very consistent. I usually just go through and check every possible option just to see if I missed anything. I even looked at your motherboard's manual and didn't find that thing about the XMP profiles!

Now that I have it set to 1600Mhz, I am wondering if I can overclock?

 

The UEFI has an option to just select the speed you want, can I do that and choose 1866mhz? And then will the 1600mhz be overclocked to 1866 without issue, and of course the 1866mhz will be normal?

 

Or is it more complicated then that?

The only thing 1860 would do is help you with CPU overclocking. There's no real world difference between the 2.

Well, I do want to hit 4.6 on my 4770k, with 1866mhz RAM.

 

I have been watching tutorials on the ROG series, but not 100% on how to go about it.

You could try, but the ram probably wouldn't be stable at 1866.
