2400mhz ram on Xeon with xmp?

[computerbuilder3211]

Ok so i have a Xeon e3 1231v3 and i was wondering if it would be able to run ram at 2400mhz with xmp enabled. I looked around, but some said yes it will work, and some said it wouldnt. So my question is will it work at the 2400mhz speed or should i buy 1600mhz ram for a few $$ less? Also yes i have a z97 mobo. I know its unnecessary but i got it on sale for cheap.

Buy the DDR3 1600, the 2400 memory even with XMP enabled will not run at 2400.

Extremely doubtful, but depends on your individual Xeon. Unless the 2400 is same price or less than say 1600 or 1866 DRAM i'd go 1600/1866

Its only a $2 difference thats why im wondering

Either way, will prob want to set the DRAM manually and never know opportunity may come up to use the DRAM with a K model CPU somewhere 😉

So for $2 more do you think i should try the 2400 ram? Will xmp work on my xeon? And if it doesnt work will it just run at a lower speed like 1600?

 

[Tradesman1]

XMP, prob not, as the profiles are for 2400, but can set manually

So should i try it and see what happens? It will still work even it it doesnt run at 2400 right? And i see xmp in my bios, but its grayed out. Is that because my current ram doesnt support it? Ive read that you can enable xmp on any haswell cpu. I currently have 1333 Samsung ram from an older computer.

 

[Tradesman1]

If you have 1333 DRAM in there now - it has no XMP profile - XMP only applies to 1600 and up DRAM

Ok thanks. So even if xmp didnt work with my cpu on the 2400 ram could i still oc it that high? And if that doesnt work, will it just run at 1600 or 1866?

The 2400 memory in that case would run at 1600. I'm running a older i5-2500k which calls for DDR3 1333, I installed DDR3 1600 CAS 8 memory, it simply clocked its self down automatically to DDR3 1333.

 

[Tradesman1]

You will have to set it manually to whatever you can best get out of it. When you first install DRAM in a mobo it goes to the mobos default, from there you either enable XMP (or sert manually

I read that the haswell locked i5s could take 2400 ram so why wouldnt my xeon?

 

[Tradesman1]

A K model i5 can OC, the Xeon's don't OC and to run 2400 it generally takes an OC of the CPU

But i heard an i5 4590 will run 2400 ram, and thats not a k series. Should i just get the 2400 ram and see what happens? Since its only $2 more i dont think it will really be that big a deal if it works or not.

Back to my original comment "Extremely doubtful, but depends on your individual Xeon" - Go ahead and try it, if it won't run at 2400, I'll help set it up for 2133, 1866 or whatever it can run. I'm in daily

Ok thanks, I think ill go ahead and order it then and see what happens.

 

[Tradesman1]

As I said, I'm in and out daily 😉

Ok the ram arrived today. I installed it, set xpm, booted it up, and the windows 10 task manager says the ram is running at 2400mhz. Is the task manager accurate or should i test it with another program to see if it is working properly?

 

[Tradesman1]

SOunds good, can double check with free app CPU-Z in the memory tab 😉 Looks like you hit the silicon lottery with your Xeon

In the CPU-Z program, on any computer i try says the ram is running at a lower speed than anything else. Am i looking at the right spot?

 

[Tradesman1]

Look in the memory tab at the frequency, it will show true freq which is half the data rate you are running at since it's DDR (DOUBLE data rate) - true freq 1200 x 2 = 2400 effective

Ok thanks that really helped. I didnt realize it was half of the frequency rate. It is showing up as 1200 so i guess its working properly. Thanks for all the help!

 

[Tradesman1]

No worries and congrats - got a really good CPU 😉

Okay, I know this is a old thread but after this read... I'm still a little confused. I've doing a "always on" media centre, NAS and gaming capable pc... I'm building a pc, and I'm using the same cpu (1231 v3) and the same. Motherboard I think (Gigabyte Z97MX-Gaming 5) but with the 212 Evo as the cooler.

Anyway, I'm wondering that if I were to buy 2400mhz compatible memory with XMP, would it actually run at 2400mhz or would the CPU limit it to 1600mhz. Especially knowing it's a locked Xeon. So... What is gonna happen? Can I just enable XMP and it'll overclock fine or will I somehow have to manually overclock it, even though Xeon are not overclockable.

Please, I've been looking for an answer for ages and I can't find one anywhere.
