First, sorry for any mistakes I'll make, english is not my native language.
My full spec:
Intel DZ68BC
Intel Core i5 2500K (no OC)
Patriot Viper Xtreme DDR3 2x4Gb
Gainward GTX 570 GS GLH (no OC)
FSP Everest 80 Plus 700W
Windows 7 x64 Home Premium (newly installed and clean)
This is my new motherboard and I have issues with it.
First of all, I did a BIOS update. Not sure if this bad or not, since I use Sandy CPU.
With 0042 system stucks on startup with Eb POST-code and goes to constant reboot.
With 0039 it shows warning message that tells my CPU is not supported, but jumps over it and load OS. OC not working.
With 0035 everything works well, no warning messages. OC not working again. BIOS shows wrong CPU frequency (5.9Ghz) as default and changing OC options for CPU or RAM has no effect. When I try to check my RAM speed with any special software it shows 560-660Mhz which is ridiculous.
So, since I can't roll back to 0028 I would like to use 0042 since it's last version with most problems solved. But for me it just doesn't work. What's up, Intel?
I gonna try 0036 and 0037 later.
Ok, let's imagine that I'll keep work with 0039 for example.
Here I experienced another problem. V-Sync.
You know, annoying horisontal displacements of picture in the middle of display? This is it.
And it's everywhere, not only in games. It's also right in OS interface, I can clearly see it while scrolling pages in browser, etc. Feels weird.
And during games I can't get rid of it, no matter if V-Sync is turned ON or not - no effect!
My display works with 60Hz refresh rate, if it matters.
I think it's motherboard fault. With my old MB everything worked fine, and I'm 100% sure in my GPU. This problem appeared right after MB replacement.
I tried different versions of nVidia drivers, I also tried different versions of MB drivers - from CD which came with it, then newer one from Intel site, and ended up with DriverPack Solution package. No difference.
