Hi everyone.

So I bought a new Kingston 16GB KIT (2x8gb) DDR3 2133MHz CL11 HyperX Savage Series RAMs, but I can't get them to run at 2133MHz. They only run at 1600 mhz, which is theirs deffault setting. I tried XML profiles (only the one that lowers the CL to 9 for 1600MHz works), tried to set my CPU tu default settings, tried to turn off turbo mode, I also tried to set everything manually:
1.65 (or higher) Memory Voltage
1.200 VccSA
11 tCL
12 tRCD
12 tRP
30 tRASmin
171 tRFC
7 tRRD
16 tWR
8 tWTR
8 tRTP
48 tRC
32 tFAW
2T CR

But nothing works. I also tried to run them at 1866, but it also couldn't boot. It just restarts 3x and then throws me back to BIOS.

My specs:
CPU: i5 2500k@4,4GHz
MB: ASRock P67 Pro 3
BIOS: version 2.0 (anything higher is meant for Ivy Bridge and causes various problems for SB processors, like BSODs, impossible to boot, crashes, etc, so I will not update it)
GPU: GTX 970
Storage: SSD: Intel 520 240GB bulk + SSD: Samsung 850 EVO 500GB + HDD: WD Red 2000GB 64MB
PSU: CORSAIR TX650W
OS: Win 7 64bit, SP1

What am I doing wrong?

IT WORKS!

I don't have a clue why, but suddenly they just work. I just tried settings from this page and PC suddenly booted after saving changes in BIOS and restarting http://www.futurelooks.com/kingston-hyperx-savage-1866mhz-16gb-ddr3-memory-reviewed/
First I tried settings fort 1866MHz and when it booted, I also tried the ones for 2133MHz (Page 2) but with lower tRFC since my mobo's max setting is 255 or something like that, but it still booted, I ran the memtest86 and it passed first test withot an error.

Then I changed settings to lower timings than XMP's settings for 2133 MHz, which it 11-12-12.

Currently I'm at:
10-11-11-27
CR:1T
tRFC: 200
1,605V

Tested it with memtest86 and first pass ended without an error.

BUT, LinX and...

1| Please pass on the SKU for your Kingston ram kit.

2| Have you made sure your BIOS is up to date? In spite of what you may think the BIOS updates come about from the community or their dev team uncovering stability issues that can only be solved by microcode. You should see if you have a copy of your existing BIOS in case the transition to the new BIOS causes your system to go belly up.

3| You forgot to include your storage, PSU and OS in your specs list.

4| If you want to go to DDR3 2133MHz specs, you will have to go for an overclock thus the OC stated against the 2133MHz reference in your product's specifications page. This should shine some light as to why you're maximum ram speed is 1600MHz since that is the maximum ram frequency you can achieve without an overclock. Which leads me to ask, what sort of cooling are you in your system?

5| Given the age of the system if it's expendable then you can tinker around with the settings to get you to the overclock to see you with 2133MHz on your ram.

1) http://www.kingston.com/datasheets/HX321C11SRK2_16.pdf

2) Updating BIOS to whichever 3.XX version is a big lotery http://forums.tweaktown.com/asrock/53784-bios-update-information-asrock-intel-6-series-x79-chipset-mother-boards.html And downgrading it back to lower version will damage BIOS. If it worked, I would at least try it, but I don't want to risk damaging my board and ending up with wasting 500€ on useless "upgrade" (new mobo, CPU, ram), since this rig still runs new games with max (or almost max) settings @60FPS.

3) Storage: SSD: Intel 520 240GB bulk + SSD: Samsung 850 EVO 500GB + HDD: WD Red 2000GB 64MB
PSU: CORSAIR TX650W
OS: Win 7 64bit, SP1

4) if you mean CPU cooling: Zalman CNPS 10X Extreme

BUT, LinX and Prime95 crashed aftera few minutes of running, so there is obviously something wrong. I will try to set them to XMP profile settings for now. My question is. I know that all those timing settings are "lower is better" but tRFC is one big mystery for me. Is it also better if it's as low as possible? How high should it be with 11-12-12-30 timings?

EDIT: The whole problem was in tRFC. If It's high enough (approx 200+) the PC will boot without any problems. If I go too low, it will just restart 3x and goes back to BIOS afterwards
