X68 Extreme3 Gen3 - Updated BIOS to 2.10 and RAM problems.

[MarkJohnson]

After updating my BIOS to 2.10 my 2133MHz RAM only works at 1600MHz and is stuck at 1.25v even if manually set to 1.5V or even 1.6v memory is rated for.

If I select 2133 and manually set timings I get error 55, If I select XMP Profile 1 or 2, I get the same error.

Any hints or clues?

ps I already cleared CMOS, Removed battery, and unplugged the PSU over night with same issues.

My Z68 System:
ASRock Z68 Extreme3 Gen3
Intel i7-2600K Stock
16GB G.skill F3-170000CL11Q-16GBZL
MSI HD 7750 eyefinity
Corsair TX 850 watt PSU

I decidedc to try my ddr3-2400 ram again since it is only 2 sticks after reading about 4 stick users having issues and my ddr3-2400 booted to ddr3-1333 9-9-9-24-1t 1.5v as normal. I selected xmp profile 1 as sual and it rebooting up fine at 9-11-11-28 2t 1.5v as usual.

This board doesn't support any high so I can't try 2400. but it runs smooth as silk once again.

I'm too burnt out on all this testing to see if my ddr3-2133 sticks will now work. Maybe tomorrow after I have fully rested.
