Can't run memo at 2000mhz on Z77-D3h

[magemaster]

Hello, i just installed a Corsair XMS3 2000mhz, and the max I can boot is 1866mhz, even if I raise VTT and IMC a lot(1.3 vtt and 1.295 imc) the system won't boot, what more settings can I try to achieve 2000mhz?

The system specs
Z77-D3H F19g bios
core i5 3570k
Corsair XMS2 2000mhz 2x4gb
Samsung 830 128gb ssd
Radeon 7770 1gb
Antec 520w HCG
Thank you!

how much dram voltage did you try? and is f19g the latest beta bios?

Tried 1.66v, then 1.7v, then 1.76v, and finally 1.8v
And yes, 19g is the latest bios, and this morning on 19g every clock past 1866(2000mhz,2133mhz...) the board booted fine, but the clock was set to 1866(showed at bios and cpu-z), so I had to go back to bios 18(latest non-beta)
The memo is stated to do 2000mhz at 1.65v

if it was booting at 2000+ this morning then you should pop out the motherboard battery for 30mins and then load optimised defaults in the bios and setup your oc/bios settings again

it could be a corrupted cmos

Sorry, I think I couldn't explain to you what is happening.
The board never booted at 2000Mhz, this morning, with 19g, if I set 2000Mhz on bios, during the boot it shows 1866Mhz, on system monitor show 1866mhz, but if I enter again on bios is still set to 2000mhz, and this happened to 2133Mhz too


Update:
Changed Corsair XMS3 2000Mhz to samsung low profile and now I can do 2000Mhz on default settings. Maybe 1.65v is too much to the board handle...

ahh i understand what you mean now

so youve changed to samsung green? and your using 1.65v? if so have you tried with 1.55v dram voltage?

[magemaster]

With samsung i can do with only 1.5v

[wazza300]

the samsung is great memory,have you tried 2133mhz @1.55v? you should be able to do that

Running memory on an Ivy Bridge system at over 1.65V is risky, it might take a while but could damage the CPU's IMC.

That Samsung memory is wild stuff, I've used in three different PCs, all different chipsets and CPUs, and it just works. I can run 16GB at 2000, 10 10 10 24 1T, at 1.4V, with unmatched DIMMs! This memory does seem to hit a wall for some users once over 2000, but 8GB has more chance of working. I can only imagine what matched DIMMs would do.

Will try higher frequencies later, will try 2400Mhz with 1.5v or 2000mhz with 1.4, such a disapointment with the corsair xms3, not even overclocking...
