The question is how are you changing the settings?
What are your RAMS? Model?
Best way to change to 1600Mhz is to use the XMP, provided that your RAMS support that option "which they probably will".
Hi, i'm using the Komputerbay 32GB 1600MHZ that i purchased from amazon.
In the BIOS, relax the memory timings to 10-10-10-28 (instead of the 9-9-9-24 as suggested in the XMP profile) and try to boot at 1600MHz.
I tried this, still no luck.
Go to Bios load setup defaults then save & exit
Go into BIOS again & navigate to the part where you can load your XMP profile for your RAMS
Bear in mind that you will not notice that much of a performance hit when you change from 1333Mhz to 1600Mhz
That being said, it should work; performance hit or not.
keep us updated
Im having the same issue. I load the xmp profile in the bios and it says 1600mhz. Once I'm in Windows and I run cpuz or even my Intel Monitoring software it shows 1333mhz. I have tried doing manual overclock, but the system doesn't boot and I have to use back to BIOS to get it up again.
I have CMZ16GX3M2A1600C9 Corsair memory.. 1.5v 1600 xmp1.3 memory.
I'm having this same sort of issue, specifically the issue James Maltese has.
OS: Win 8 64 bit Pro
Memory: Corsair. DDR3. 4GB x 2 . CML8GX3M2A1600C9B . I use "the 9-9-9-24 as suggested in the XMP profile"
Like James, I load the xmp memory profile in the BIOS and it shows 1600 Mhz. Once in windows the memory speed is reported as 1333 Mhz, both in the Intel Desktop Tool and in windows task manager.
At the risk of introducing a separate issue: I also sporadically get a 3 beep code (which designates a memory fault) and a failure to boot. I can rectify this by turning the power supply switch off then on. I can then boot as normal. This issue seems to arise regardless of whether I have set the memory speed at 1333 Mhz (auto memory profile) or 1600 Mhz (xmp memory profile). James (Jimmy), or anyone else, do you experience this?
I have run memtest86+ and the memory completes a pass with no errors.
Edit 1: BIOS Version 0059: GAZ7711H.86A.0059.2012.1106.1053. There is a newer BIOS version out, 0060, but nothing in the release notes to indicate these issues have been addressed.
Edit 2: When I get the 3 beep code I also get a Status Code of "20": "Resuming from [S2] State"
Can you guys download CPU-Z and confirm that when you set the memory's XMP profile in the BIOS that CPU-Z reports a DRAM frequency of approx 800Mhz(x2 = 1600Mhz) under the memory tab.
I say this because my memory is running at 1600Mhz, but all Intel tools report 1333MHz.
Intel Desktop tools only shows the default speed MHZ of ram. If you load the XMP profile in bios and the bios states that the ram is running at 1600Mhz then it is.
John.. i am not getting the 3 beep codes randomly, like you are..but your other symptoms are the same as mine. I only get the 3 beeps, when I manually overclock the memory.. I then have to use the Back to Bios button to reset the bios and set it back to defaults.
Yes manuel..my cpu-z is showing 798mhz DRAM frequency and intel utilities are showing my memory speed at 1333mhz...
the only thing I could think of is that because the memory is set to 1.5v for this particular Mobo, that the utilities calculating that versus 1.65volts which the older core i series processors used.
Well that means everything is fine James. You are running the memory at 1600Mhz.
Like Lance pointed out above your posts, the speed reported by Intel in it's tools, is the default speed of the ram (so 1333MHz).
The RAMS are 1600MHZ
However, Martin has loaded his board up to the max with the RAMS that this board can support "32GB of RAM". Hence, he loaded the memory controller to the MAX. So any kind of over clocking will result that the controller can't take.
Please try to use only the blue DIMMS 'which means that you will be using only 16GB or RAM" then activate the XMP thingy properly & it will work.
Man I don't know why you need 32GB of RAM. Unless, you are using RAM disk they are useless.
