I recently bought some g.skill sniper 1866 mhz ram but it only runs at 1600 via cpuz, how can I get this to full speed.
System
Phenom IIx6 1100t
asus m4a89td pro usb 3.o
CF 5870's
samsung spinpoint 7200 rpm 500gb hard drive
650w xfx modular psu
windows 7 pro

My timings are set to factory 9,10,9,28
 
Solution
Raise your FSB Frequency, start with 240 MHz and continue to go up until something close or exact is a option. If 2000 MHz is 'it' then still use a FSB of 240+ MHz and 2000 MHz DDR3. Also, this will cause your CPU to OC. OC the RAM will require at least a DRAM Voltage increase and probably a QPI/VTT/VCCIO Voltage increase at minimum.

edit: the 'Sandy Bridge' RAM offers different Frequencies than your AMD or prior Intel CPUs; your supported are: 2000(O.C.)/1600/1333/1066 MHz. I realize 1866 is a selectable option, but I too understand stability.

AMD 1100t
3300 / 200 = '16.5'
3300 / 240 = '13.75' or 14

14 * 240 = 3.36GHz
17 * 240 = 4.08GHz and will require a vCore ~1.5v and really good HSF.

Math problem:
1600/200 = 1866/X ...
ok so I set all that and stil get errors at exactly test 7? No matter how I set it up its errors at test 7. but while usuing the pc with any of those settings it seems stable. I'm gonna try auto which sets it to 1600 by defualt and see where the errors start, any more suggestions in the mean time?
 
OK so I ran this ram everyway I can, auto 1600, errors a test 7! I OC to 2000mhz 7 errors b4 test 7 then all errors after, and put it back to your settings originally and no errors till test 7. I'll check out that link but I think i'm just gonna let it ride as I have no probs with my pc so far, your opinion?
 
On a similar thread a GSKILL Administrator suggested to ignore Test 7 errors. You are exceeding the AMD CPU's IMC limits running 1600 MHz DDR3 and faster; as stated test 7 is not a RAM test as such "Errors from this test are not used to calculate BadRAM patterns."

Therefore to test the IMC Load Defaults in the BIOS and re-run the tests.

Next, I assume that you are running the latest non-Beta BIOS version 2001.

Lastly, you might want to report it to ASUS so they can look into a BIOS upgrade to correct the issue.
