Think 1.65V memory will be OK with Ivy Bridge?

Bought 16GB Kingston Ram a little while back, but failed to notice it's rated 1.65V for 1600Mhz.

Now I believe this is not really a problem for Sandy Bridge, despite the initial impression that one shouldn't go over 1.5V on memory.

But I am left wondering about Ivy Bridge. I know it is a bit on an unknown thing to be questioning, but do you guys reckon 1.65V memory will be OK for Ivy?

Or should I invest in some other, lower voltage ram?
 
No it wont be, the highest that you can safely go to on SB / IB is 1.575v. Anything more than that is asking for a fried motherboard or CPU.

Have you tried your kingston ram at a lower voltage first? It would most likely work at 1.5v and 1600 Mhz.
 
Ive been running my ocz reapers at 1.66v for over two years now. The voltage increments only go up in two's, ie 1.64-1.66v. Is there any x58 boards where you can select 1.65 exactly?
 
I have 8gb of Kingston grey and 4gb of corsair xms 3 and they run at 1.53v with no problems at 1600mhz. Might even go lower yet I've not tried. just set the ram voltage to 1.55v and I'm 99% sure you'll have no problems at 1600mhz.

if all is fine after abit of memtest drop the voltage to 1.54 and try again until you get lowest voltage and full stability.
 
If the memory is rated at 1.65V then 1.65V DRAM voltage will be fine, if it overvolts just drop the memory dram voltage to 1.60v

I just got my ram working at 1905 Mhz, 7-8-7-21-72-1T at 190 BCLK which allows me much higher CPU clocks, but it requires 1.6695v, and 1.3875 QPI voltage.

At 158 FSB and 1902 Mhz ram, it works with 1.65625v and 1.35v QPI. At 1.3375v QPI is BSODs in a few minutes of stressing.

The large increase in QPI is mainly needed for the BCLK I believe, plus the ram needs at least 1.35v QPI for 1900 Mhz.

My mobos DRAM voltage has 1.643v, 1.65625v, and 1.6695v.

Im sure you can go a little bit over 1.65v on X58 without any problems. I get more stability at higher ram clocks with 1.696v, but that only gets me up to 1933 Mhz which isnt worth any risk, as both my ram and X58 are rated for 1.65v max.

1.66v wont be any problem on X58, but I wouldnt risk going any higher than that as then both the CPU and Ram are running significantly beyond their safe limit.
 
Ive never clocked the reapers, but im sure theyd run higher on 1.66v with slacker timings. 12gb coming on monday so the reapers will be sold off.
