Fan control is set to silent at the moment. For reference, BIOS is F7.
All the fans seem to do is switch between around half speed and full speed. There's doesn't seem to be the "proportional" adjustment of fan speed with temperature that I was expecting.
The switch between half and full speed seems almost random, although I'd guess that perhaps it goes to full when something warms up and reverts to half when it's cooler again.
I expected much more sophisticated fan control.
It is possible to switch between Voltage and PWM control for the CPU fan, but I don't recall seeing any such option for the system fans.
Ideas, anyone ?
Dude lol it is fan control, and your temperatures are usually in levels, either idle or load, thus temperature spike, and then fan speed spike. If you want really precise fan speed control, you might want to think about a fan controller.
I think by default all system fans are voltage mode or it might go with CPU voltage/PWM setting, you need 4-pin fan for PWM mode. The difference really isn't that much, but PWM would be more sloped than jagged.

This XMP RAM issue you guys are having; any chance your running 1.65V & that is causing an issue...?
I am curious because I was planning on running me kingston Hyper X 1600 (16Gb) that I have been running on XMP 1600 @ 1.65V... Is this an issue perhaps?
Dude you really shouldn't have an issue, i have the same memory as you, both the 16GB 1600mhz kit and the 16GB 2133mhz kit, both work fine with XMP. A lot of the issues are rooted to the fact that XMP profile wont set the DRAm voltage, the user still has to do it, that is what I have seen. Also they should all update to the latest BIOS if they have issues. Try it out, you shouldn't have issues.

Gigabyte GA-Z77X-UD5H mobo running f7 bios
1x G.SKILL Ripjaws X Series 8GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-1600C9S-8GXM
sapphire radeon 6959 2gb
i'm trying to figure out if this is a memory issue or a mobo issue..any thoughts?
Update your BIOS to F8D, BTW the motherboard should beep when it starts. You have a POST code display, forget the beeps, what does the POST code display say? For it to just restart and go into the BIOS and say OC fail, it has to first hang on a POST code, unless there is another issue. If two are identical with same memory, cpu, and motherboard, and same BIOS and PSU. Then i would think your memory kit isn't good. BTW how often do you do windows updates??? Make sure both boards are on the same XMP, it could be that Windows Update is causing a driver to force the system to reset its BIOS settings, you can blame UEFI for allowing the OS to touch the workings of the BIOS.
BTW try manually setting your voltage on the memory to 1.65v, I think perhaps that you need to update your BIOS and see if it occurs.
BTW it is 3570, not 3570K right?

And then it was restarting and then the PC turned off,(no lights, fans turned off) and then It came back on with no display and then turned off again then on again with no display, and it keeps doing this.
My temps were great(high temps were in the lower mid 70's, and the majority of the time it was in the mid 60's)
yea i think perhaps something got damaged, and that is why on restart it was re-initialized and failed. Do you have other memory or PSU?
Did you try the cooler thing?Edited by Sin0822 - 5/27/12 at 3:44pm
