Ram Speed questions!

Well if you multiply that by 2 you have your answer. So no it seems not. Are you using the XMP profile?
Isn't that only for Dual channel?
Triple channel multiply by 3, and it's overclocked to around 2.2MHz.
You could try changing the FSB : Dram ratio.

That's exactly what i said in one of my previous post, but they said it's wrong.

RAM runs a "Double Data Rate"(get it? DDR) No matter the configuration. Single, Dual, Triple, Quad, makes no difference in it's actual speed.
 
Well if you can't use the XMP profile then it will just run the "standard JDEC profile" so that is what you are getting. Only thing you can do is write down all the XMP timings from the SPD Tab and put them in yourself if you want the advertised speeds.

This board uses a non uefi bios- the user manual is pretty sparce for a overclockers/enthusiast board, even ASRock and Asus manuals are more detailed.

The only places I could suggest is Memory configuration.
 
I should be soon at home i will post a few Bios pics.
 
@bogmali you're making me things difficult :slap:
:p

Well XMP has been around long before UEFI but it only goes back so far and only was available with later chipsets

I Know XMP was around during Core 2. There has to be more configuration options than that manual has.

Well it being a "server chip" oriented board it may just not be an option? Not like you would be buying ECC RAM with XMP for example.

You're confusing memory channels and memory data rate they are two separate technologies.

Theoretically, dual-channel configurations double the memory bandwidth when compared to single-channel configurations. This should not be confused with double data rate (DDR) memory, which doubles the usage of DRAM bus by transferring data both on the rising and falling edges of the memory bus clock signals.

DDR should not be confused with dual channel, in which each memory channel accesses two RAM modules simultaneously. The two technologies are independent of each other and many motherboards use both, by using DDR memory in a dual channel configuration.

I fired up my X5680's last night and I am still playing with the settings since it dumped my old ones when I went to load A56 BIOS :banghead:

I'll post some screenies once I get my stable settings back.

The BIOS only lists DDR-1333 so do you need to overclock the RAM for speeds higher then 1333? This thread has SR-2 owners talking about overclock settings so maybe it can help you out. https://hardforum.com/threads/sr-2-optimization-thread.1541357/
Have you tried playing with the CPU Frequency Setting to see if that changes your RAM speed?

Check your DIMM voltages, you're running your 1.5v memory at 1.65v!

Force the DIMM voltages down to 1.5V in BIOS, and set memory speeds to 14x (1867MHz), then set your timings to what G.Skill rates the memory at.
 
set memory speeds to 14x (1867MHz)
Setting the CPU Uncore Frequency (Mhz) to 1867 Mhz (14 X) changes the memory frequency? Or were you referring to another setting?
I thought the only way to overclock ram on this mobo was by upping the CPU Frequency Setting? Is CPU Frequency Setting the same as BCLK?

Nothing unusual there my XMP Profile for 2400 is 1.65v most "OC profiles" are. 1.65 was actually the Default voltage for that chipset anyways.

Edit: You see mine uses 1.65 on the XMP. His chipset is actually that by default, He would be undervolting for his setup at 1.5V.

Just to offer another idea, the sticker on the ram does say 1.50V. And his CPU-Z shows 1.50V for all in the timings table.
G.Skill shows a Tested Speed 1866Mhz at 1.50V http://www.gskill.com/en/product/f3-14900cl9d-8gbxl
Also on NewEgg it shows his DDR3 1866 with 1.5V - http://www.newegg.com/Product/Product.aspx?Item=N82E16820231455

But I'm no ram expert so INSTG8R could be right and 1.65V is the best voltage. :ohwell:

My ram at 2400 calls for 1.65 as well.

By the way perhaps on intel for ecc and xmp, on Amd there is ecc and xmp lol

I think those are ram profiles. You had there knoxx29, id leave memory 1 and 2 at auto and try 3.

Changing the MCH strap will overclock ram too (Memory Controller Hub)

Could you try to be a bit more condescending? :slap:

It's possible that he needs an earlier model Ram that is meant to run at 1.65V, from Ivy Bridge chip set onwards voltages reduced to 1.5V.

RAM is set at 1.65V in in the bios.
 
G.Skill only lists up to DDR3 1600 in triple channel kits, and the command rate should be set to 2.
1866 should work, i'd love to get my hands on one to try it.
