is the i7 1.65v limit true?

Hey all, quick question...

I'm sure we've all heard about the 1.65 voltage limit on DRAM for the i7s...however, I read online (somewhere) that there really is NOT a set voltage "limit" to this DRAM, but a set voltage RATIO that one must stay within for healthy, normal operation. In essence, 1.65v is at the upper end of the voltage ratio for a normal processor-to-DRAM voltage relationship. Is this true? Intel says stay below 1.65, but I swear I've read somewhere (tomshardware.com perhaps?) that you can be safe as long as you stay within that ratio...

Anyways, in short, is it true that you can safely up your DRAM voltage AS LONG AS you up your CPU voltage and stay within this magic ratio? Has anybody heard of this? If so, does anybody know that ratio? I thought I remembered it being below 10%? I could be totally off

Thanks,

Sal

lol hello Sal:)

The rule of thumb is to not have more than .50v difference between the DRAM voltage and the QPI/DRAM bus voltage. More than this can cause damage. I can personally attest to that;)

Ahh yes, that's it, I remember that now! Im sorry that you had to find out first hand:(

All the best,
