1866 Mhz in BIOS showing up as 1333 Mhz in task manager.

dan1eru · Jul 19, 2014

My current build:

Intel i5 4670k
HyperX Fury (2x4gb) @ 1866 Mhz
Nvidia Geforce GTX 770 (4gb of vram)
Intel z97 mobo

Earlier tonight I noticed in the task manager (windows 8.1) that my ram, which should be 1866 Mhz, is currently running at 1333 Mhz. A quick google search indicated that i need to change the speed in the BIOS, so I booted into the BIOS. In the BIOS, it displayed my ram as running at 1866. I need clarification as to whether my ram is actually running at 1866 Mhz, or if I'm misreading something in the BIOS. Any help is appreciated, thanks!!

Have you enabled XMP?

apparently my 2 sticks of ram are supposed to automatically overclock themselves to whatever speed I had purchased, according to Kingston (the manufacturer). It looks like it is running at 1866 in my BIOS, but is not in Task manager. There is also no "enable" option for XMP because of this feature.

They should automatically overclock if you select an XMP profile, however this doesn't always work. Just manually overclock the RAM to the settings that it was advertised at and you should be fine.

I can't actually select an xmp
Profile, as there is no option to in the BIOS. How would I go about manually overclocking?

There will be an XMP option, it's just hidden somewhere. What motherboard do you have? I need to know to either help you find XMP or the RAM timings settings.

I have an asus z97-a, and in the "ez tuning" section of the bios, the xmp drop down menu only presents me with a "disabled" option

Ok, That board has EZ XMP which is not easy at all. On your motherboard, top right corner, under the MemOK button there is an EZ_XMP switch. Flick this to on and you should have access to XMP and overclocking.

Yep, want to enable XMP and select the profile 1 or proper freq...there aren't any mobos, that simply automatically set your DRAM up to 1866 or above, in fact very few that even will default to 1600.....sounds like the Kingston guy needs to find out what he's talking about...When first installed all DRAM goes to the mobos default, which generally today is 1333 for Intel and 1066 or 1333 for AMD

will try promptly after this game of dota!

Tradesman1 :

thank you! I emailed kingston about this issue and they have yet to respond to me. I cant believe I reinstalled my RAM like 5 times thinking that it was a mobo issue.

Tradesman1 · Jul 19, 2014

What does it show in CPU-Z in the memory tab - if 933 as freq then you are at 1866, you may be seeing the 1333 as a result of it reading the default SPD freq (many programs read that)

dan1eru · Jul 19, 2014

Tradesman1 :

Where exactly can I find that information? In my BIOS or task manager?

Tradesman1 · Jul 20, 2014

Download CPU-Z (it's a free app) and run it, tells you lot's of info, model # of mobo, CPU info, DRAM info, etc........will want to see frequency in the Memory tab

dan1eru · Jul 20, 2014

Tradesman1 :

It does say 933 in Cpu-z. Being that this is my first build and im still relatively new to hardware, can you explain why Cpu-z is able to validate that my ram is running at 1866 Mhz (even though it displays 933), and why task manager fails to show an accurate speed?

Tradesman1 · Jul 20, 2014

As mentioned Task Manager looks to the SPD of the sticks at the default boot speed of 1333, the 933 is the true freq of the DRAM, since this is DDR DOUBLE data Rate, then you take true freq (933) x 2 = 1866 effective - so it appears you did get XMP enabled and yes it's running at 1866

byza · Jul 20, 2014

Glad you got XMP working. Sometimes even with XMP enabled you don't get the speed you are supposed to and need to OC manually. Don't forget to close the thread.

Tradesman1 :

Kingston Fury ram does not have an xmp profile as mentioned in many reviews of the ram online and I also know from experience as a I have the ram installed in my system.
It does however defualt to 1866 mhz when installed in the system because of the way it is programed. As confirmed in the bios and CPU-Z.

Yes the Fury line they have released uses PnP (plug and Play), and if the mobo supports it, the newer chipsets should

I have the same issue but I don't have an option to enable XMP and have to manually set the DRAM frequency which i have done, but when I take a look in task manage I'm still at 1333Mhz... What do I do in this situation?

Tradesman1 · Jun 12, 2016

Task manager tends to show the defaults of the mobo - should start a new thread and include your mobo, CPU and DRAM model #(s)

1866 Mhz in BIOS showing up as 1333 Mhz in task manager.
