Slightly overvolting RAM

First off, I suppose I could post this at Tom's but I've forgotten my username/PW over there.

I've been experiencing some memory issues with my G.Skill DDR2 800. Model CL5D-4GBPQ, a very popular, highly regarded model (albeit a rather standard one) which I've been using in all my machines since 2007 besides some OCZ Reaper 1066 in 2010/11 before I got rid of my tower prior to traveling overseas with a laptop.

The manufacturer recommends 1.8 - 1.9V. My research indicates that this specific RAM runs at its most stable at 1.9V, and people commonly experience issues running it below that. My mobo on the other hand allows a range of voltages to be selected using manual mode in the BIOS, instead of being able to just typing them out, the closest of which is 1.92V.

I've picked the 1.92V, and was just wondering if 0.02V really makes a difference?

And yes, MemTest is a pass. Overclocking isn't a concern, it runs at the standard 5-5-5-15 timings.

Allow me to make an analogy....

My submarine's crush depth is 800 meters... can I take it to 802 meters?

The answer is yes.

The "crush depth" on this model of RAM isn't 1.9V. It's routinely increased it to 2.2V or higher when overclocking. 1.9V is just:

--the maximum advised voltage for stock speed and timings
--the point beyond which, technically, the manufacturer's warranty is void

My question was solely in regard to memory stability w/slight overvoltage and no overclock. 1.92V on this model poses absolutely no threat of frying it.

As of yet, I've had no recurrences of the problems that were occurring prior to increasing the voltage 1.92V. The increase seems to have worked perfectly. So far.

you're fine. 0.02V isn't going to break your back on this, it's not even going to contribute to a shorter lifetime

It depends on the brand of RAM, really. Some brands are more voltage tolerant than others, but in my experience undervolting is more problematic than overvolting since discharging any extra voltage is easier than trying to draw more into the system from the PSU connections. Basically, watch your MB's readings to see if any funny business with the voltage levels. The trick here is to make sure there's is as little variability as possible. So, before even trying this I suggest checking out your PSU.

What I was trying to ask was if overvolting without overclocking is OK. I think it's just fine though.

It will affect lifetime, just not in any meaningful way that he will notice.

This post gave me cancer.

It's fine.
