You are not running XMP profile,since Dram Timing is not Auto and Performance on Turbo.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

I tried auto as well, BSODs too...

In fact there might be a bug with UD3H bios - I found out the PC keeps restarting and bios gives error message saying something about wrong settings if I set BCLK manually to 100 and enable the XMP profile.

Gskill ram at 2300mhz. Not fully stable at least the system boots and booted to windows with 2300mhz. Just need to get up to 2400mhz.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

update: I resetted the bios, loaded optimized defaults, after that I ONLY enabled the XMP profile, booted into windows, started Prime95 (memory test), and got BSOD within minutes. Something is very wrong.
I tried different memory banks, same result.


I got the latest F12l bios btw.

Try manually set your RAM.
Ace,
try 11-12-12 for 2400

This is my latest 2666:

I think I tried those settings with ram speed set to 2400 in bios no boot, but I will try again with those settings. So instead of trying 2400mhz ram with 100bclk I tried to set ram to 2200 and then increase bclk to 109 to get ram to 2400mhz. System would boot all they way up to 108blck and would not boot at 109 bclk this was with 1.200 vtt. I did not try to drop ram out of equation to see if bclk is capable of 109.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

hes undervolting the cpu with dvid set to -0.110v,that way it reduces his load cpu voltage by that amount

Just curious since I had to increase mine to +0.045 to get a stable 4.5MHz.

i dont think hes overclocking,just stock clocks

Perhaps you should boot to a Memtest86 CD testing the RAM to see what happens.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

Ok I was this close to saying my memory is totally incompatible with UD3H (it's very possible it is anyway!), but then I dug up pair of 1GB crappy modules and booted with those (default bios settings of course). Guess what, Prime95 crashed me into BSOD again! At this point I have absolutely no idea what's going on. The PC is not overheating, nothing is overclocked. I am running F11 bios. It cannot get more default than this :(

I welcome any idea.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

What is the BSOD error code?????

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

Give me some time, it should not be hard to reproduce, lol.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

what test are you running in prime95? it could well be cpu voltage too low?

Did you read my post where I said I loaded optimized defaults and ONLY thing I changed was enabling the XMP profile?...


What I run is custom test, min FFT size 2048, max 4096, and set memory to use to 12GB (that should give me enough for system functionality). Basically with these settings I mostly test the memory, not cpu.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

Most likely need to adjust vtt or imc voltage for 12gb of ram.
