wow, again by my z77x ud3h causing problems

this is the second time i turn the pc and the bios was screwed, the mobo copied the bios2, but why does this happen?

everything was fine, pc shut down fine, overclock is stable, all pc parts are fine, no power cuts, nothing, the other time was the same

also, the lan card on my mobo sucks, it can´t handle torrents or heavy number of connections, and yes i tested my lan on other pc, the modem is fine, the cable, etc, it`s the crap lan used in ud3h, if you put 3 torrents it is almost 99% sure the network will fail and you need to restart windows, and yes using latest drivers,

In my bios in cpu voltage control i have noticed with all bios available that the value on the left of "auto" is ever set to 1.230v. This appear also when i have loaded optimized default and than is all on the factory default. With ud5h have you the same value?

When i have to oc my cpu with positive offset i start from 1.230 vcore?? mad.gif

It depends upon what frequency you're OC'ing to or from.

full default. no oc. living parameters on auto the mobo show me 1.230 on the left...it's normal value?

It's no wonder people trying to OC for the first time get so confused when it comes to C states. About C states being on Auto: First people told me my SSD's were going to under perform and they could prove it. Then some said I would not get a stable overclock. And there were other reasons I don't remember now. Wrong.

It's probably true some other boards respond differently, but I know my 2xUD5H boards pretty well, I've had them since they hit Newegg.
Guides are OK , and I believe I contributed to that one, but at some point if you are going to OC you should learn your board for yourself and see what works and what doesn't. If something works for you, that's cool, do whatever you want. I've never knowingly given anyone bad advice, but if they test everything and find something that works for them that doesn't agree with mine, it doesn't surprise me and they should go for whatever works.

Default VCore values are always higher than whats really needed to run at stock frequencies. That's more like the VCore for 4.5Ghz

but in several screenshots on internet i see a minor voltage in normal state...

Firstly, they spin at full speed no matter what the BIOS setting (standard, silent, custom at all values). Secondly, EasyTune6 only slightly adjusts the SYS fan speeds down, even with the most extreme plots on its graph -- and the application crashes on its own (Windows 7 64-bit) consistently within an hour or so of doing nothing. Thirdly, HWMonitor Pro and SpeedFan simply do not control PWM fan speed, period, even though they are advertised to be capable of it. Fourth, and worst of all: there is not a single fan controller on the market that controls PWM fans with 4-pin connectors. No joke!
The fact that there is no demand for these minimum requirements, from a fan controller to a firmware fix, suggests that hardly any consumers spend the time to figure these things out (far from rocket science)!

I had used speedfan on my now retired computer for a few years to control the speed of the cpu fan.

Based on hpmoon's post I downloaded the most recent version of speedfan to see if I could get it to control SYSFAN_1 as this is the only fan header that I have a fan connected that can be controlled. As reported earlier, this fan header can be voltage controlled as well as pwm. As I have a 3-pin fan connected to it I confirmed that ET6 was able to control this fan's speed. Then I used speedfan to successfully control same fan. Although I can't confirm as I don't have a 4-pin fan, I believe speedfan can separately control three sets of fans. One via cpu fan header, one through SYSFAN_1 fan header, and one through SYSFAN_2 and 3 fan header. Again, as already reported, cpu fan header and SYSFAN_1 fan header can control either by voltage or pwm. SYSFAN_2 and 3 can only be controlled via pwm. SYSFAN_4 cannot be controlled through the motherboard.

I admit ET6 is not very useful when it comes to controlling the system fans as it can only adjust the fans based on the system temp which does not vary much. And it seems to crash often.

Yeah, I don't know what they were thinking with the fan headers, especially header 4 full on voltage all the time. Maybe that's one of the things that finally pushed me into water cooling.
