VRAM overclocking 7950s 1.6v Safe limits ?

[ViRuS2k]

Does anyone know whats save limits when overclocking memory on these cards ?

1.6v is default and 1.7v is max

surely 1v extra will not damage the memory right ? or will it.
need some imput has anyone or does anyone add more volts to there memory on there cards and how long have you had the cards memory overclocked at.

I have great cores on my cards but the memory sucks on them max @1.6v is 1500 though with 1.7v i can hit 1650. lol

1v will fry it

But should be fine with 0.1v

Wouldn't worry too much about the memory OC's, unless you're benching 1500 should be enough, especially if you have two of them

With 7970's I've never needed more than 1.625v before hitting correction. I'd say 1.7v is a little excessive.

I just wanted to know if 1.7v is fine over 1.6v and yeah 0.1v lol thats not a lot shouldnt fry anything should it.

and i dont hit correction if i use 1.6v past 1500 i hit artifacts lol
though with 1.7v artifacts vanish and i can move past the barrier.....

just dont want to fry the memory with prolong use of 1.7v unless its very very safe to do so.

I was advised 1.7v was too much for the memory unless its got really good cooling.

Have you tried voltages below 1.7v? I would say 1.65v should be sustainable for prolonged use.

With the core@1256v, memory running@1668v I got stable clocks@1200MHz/1823MHz on my 7970 MSI OC, but I only benched, never kept it at those voltages as the vram is usually the first to pop.
