Running RAM at lower voltage than manufacturers recommended ok?

Hi every one, as the title says is this ok to do?
The reason i ask is because I have had constant blue screens for the past 5 or so months and narrowed the problem down to my ram.
I was planning on buying a new stick but thought i would try altering the settings in the bios to make it more stable in the mean time, after a few hours of tinkering i tried lowered the voltage from 1.5 to 1.35 and now my system seems to be completely stable and i haven't had a crash since.
I assume this is ok to do and is not going to cause more damage than good?

Also another question if someone could help me understand this.
At first i thought my gpu was the culprit so i bought a new one, this made the bsod's a lot less frequent as my first gpu was a bit dodgy, but they still happened.
But when i run my graphics from the apu instead of the graphics card, the crashes happen once i a blue moon, but since the on board graphics use the systems RAM as VRAM i would have thought the crashes would have been more frequent rather than less, because the RAM will be in use more, but the opposite is true.
The only logical explanation i can think of is that my RAM was overheating, because the airflow in my case is really bad, and without a dedicated card the temperature drops.
And that's why when i lower the voltage of my RAM my system is stable, would i be right in assuming this? I'm curious because with a quick google search every one says that RAM very very rarely over heats, but maybe i just got unlucky and my RAM is just less tolerant to heat?

The memory is the culprit, a good stick won't fail the test even after hours of testing and multiple passes. But if undervolting is not causing BSoDs, then you may just get it to work for quite some time, I'd recommend getting a new one, or atleast RMA the current one if its under warranty. The PSU is not the best quality, nowhere close, but, it shouldn't fail on such loads.
VRAM heats up, not RAM. At stock, no memory will heat up enough (Unless you have a super-duper mega ultra, unknown memory) to cause BSoD, 4-6 Memtest passes will determine if the RAM is really the culprit or not. Lowering Voltage doesn't have any bad effects to the rig. Lowering voltage does cool down the memory but only by a few notches, what is your CPU and MoBo and GPU? What brand is your Memory and what model is the PSU?

A8 6600k
Sapphire R9 270
Corsair builder 500 watt
Kingston 8gb DDR3 1600 RAM can't remember which one exactly.
And my RAM has failed mem test a few times, still not a single BSOD after undervolting it though, i upped the voltage back to stock earlier on and it crashed within 15 mins.

+1 Sounds like a bad stick
