Dram voltage 1.79 dangerous?
I have 3 sticks of OCZ3G1600LVGK. If I set dram voltage to auto, and dram timing to auto, I get
DDR 1520 MHz (cpu 190x20=3.8GHz, 8x dram multi)
FSB: 190 QPI 6.8 GT/s
Memory bandwidth 16889 MB/s
Dram voltage is 1.58v
I wanted to run it at rated spec which is 1600MHz and timing, and I got
DDR 1600 MHz (200x19, 8x dram multi)
FSB:200 QPI 7.1 GT/s
CAS 8-9-9-19 (as shown in CPUZ in spd)
I got DDR voltage at 1.79V
and memory bandwidth 16889 MB/s
Is 1.79v too high?
Why is bandwidth the same?
BTW, I am running i7 with vcore 1.25v and vtt at 1.22v
Hardware as in my sig.
According to the OCZ website these sticks operate at 1.65volts. I would just try to run it by manually entering the info if the BIOS isn't doing it properly.
Thanks. I signed up at OCZ forum and post a support question. Steve's answer was 1.65v but increase QPI vtt to 1.3 or 1.35. I tried 1.3 and it is not stable. I'll try 1.35v, but is it too high?
According to intel, anything over 1.65 can fry your motherboard.
What are you using to get these bandwidth and voltage readings? Software voltage readings aren't necessarily accurate, and I would avoid using any Auto voltage settings on your memory.
The 1.79v was shown in bios "health" page. Also, HWMonitor shows VIN 1.79. When I tested the cpu stability, I ran the ram at 1066 speed, and left voltage at auto. After I am done with cpu stability, I started to bring ram up the speed of stated spec, but forgot to set the voltage and left it at auto. It ran for about 3-4 hours and was stable. There are some ram's from OCZ that people run with 1.8v, but maybe not this one. I have run it at 1.64v and QPI at 1.3v, but not stable. I'll increase QPI, but I really question the benefit since running it at 1520 at loose timing, instead of 1600 at the tighter timing gave the same bandwidth (according to memtest86+ v2.11).
I am out of town, so cannot do any more testing until next week.
