Hi all.
I've searched this forum quite often during the last few weeks, trying to figure out the right configuration for my new computer. But this is my first message, and I'd be grateful if anybody could help me. I've searched for other threads with the same problems I have, but none found.
This is the configuration I chose:
- Asus P8Z77-V Pro.
- Intel i7 3770k.
- 4x4Gb Corsair Vengeande Red 1866MHz (CMZ16GX3M4X1866C9R).
- Gigabyte GTX 670 OC.
- Crucial M4 128Gb.
- Seagate Barracuda 3Tb.
I built the computer last weekend and had some issues with, apparently, the memory. BSOD, random errors while reading files, etc. Tests with Memtest86 indicate one good stick, one bad stick, and two that only fail when accompanied by the one that's OK (?).
But what really puzzles me is the fact that the BIOS shows very high DRAM voltage readings, between 2.4v and 2.5v. If I select the XMP mode in the BIOS, the sticks are correctly recognised (frequency, timing and voltages), but they remain at almost 2.5v. Trying to set the voltages manually is useless - the BIOS just ignores my inputs. HWiNFO64 shows the same voltages high values as the BIOS. CPU (1.092v while in BIOS) and VCCSA (0.925v) seem OK, but PLL (2.775v) and PCH (2.012v) seem also way too high.
I'm no expert, but as far as I know 1.5v is a normal value for DDR3 @1866, and voltages as high as 1.55 or 1.60 are only recommended for overclocking. What can be the reason my BIOS sets (or maybe just reads?) such high values?
I'm having other issues with the MOBO (false and unstable CPU FAN readings, too low CPU temperature reading) but that with the voltage is the most worrying one.
I've already placed an question at Asus' Support but still waiting for a reply.
Thank you very much in advance,
Guille
