Z77-D3H Cannot change ram timings/frequency

Hi,

Sorry am a bit new to overclocking/tweaking RAM so may just be doing something stupid.

I have samasung green two sticks of 4GB and Z77-D3H, I have tried upping the multiplier of my memory to set the speed too 1800 and have tired setting the timings lower (10-10-10-28) however nothing actually seems to change? In the bios menu it show I have set them and they do save however if boot into windows or goto 3d bios that shows status the default settings of 1600MHz and the default timings of 11-11-11-28.

Would appreciate it if any one could point out what I am doing wrong?

Thanks

what dram voltage are you setting? if not enough it will revert to stock speed/timings or not boot

Have tried a few different ones between 1.4 upto 1.7, it does not even accept 10-10-10-28 at stock frequency. I guess I could try dropping frequency and raising timing to confirm if it is stability issue.

could ask here as some users have same board/ram,i know its a pain to join but cant think whatelse you can try

Ok cheers, I guess will give that a go, is very strange, does not even seem accept underclock, so do not think its due to being unstable.
