How much is too much vdimm?

I have been only feeding my memory 2.65 or sometimes 2.75v, and been fighting stability in OCing to 3ghz with a 2.4b(sl6ef) and 512mb OCZ PC3500el. I read in another thread someone posted that 2.9v is not "too much" for their DDR. Are my bios vdimm settings of 2.95 or even 3.05v going to cause any problems to my ram.

As a bold experiment, I am at 169fsb right now 3:4 cpu:ram for DDR 450 and at 3.05vvdimm, SPD timings. I can assure you that these settings have never have passed the first line of Prime 95. Well I am at 45 minutes right now. Sandra 2003 was 2473. I'm a little excited to say the least. Am I going to be burying this ram next week?

Thanks

I wouldn't push any OCZ ram that high....I hear some of the quality twinmos ram can run 2.9v but they don't even try to run it at 3.0v...

I only run my pc3000 at ddr450 at 2.7v (2.73v actual)...

I think that sandr score must be 3400's right and not 2400's??? or is that buffered score???

My bad... 3473! Yeah, I don't plan to leave it at this voltage. I was just amazed that it is running this fast and smooth. But so far, for $140, I think I was taken on this memory. It's supposed to be awesome, but at 1:1 ratio I usually run it far less than rated speed and get errors in mem86 and I believe it is the culprit of my systems instabilities.

I don't recommend anything over 2.8 volts.
