Who's willing to go over 1.65 VDIMM on their Core i7 system?

[AdamK47]

According to this thread it's possible to increase the VDIMM memory beyond 1.65V as long as it's within 1.5 times that of VTT. I don't want to try out the theory just yet. I'm going to wait until there are substantial reports that this is true.

its not that the IMC will immediately fry if you send too much voltage, it'll just degrade a lot faster.

that 1.5x Vtt sounds like BS to me since the two voltages aren't related.

More information and reports. Some of those on there with Core i7s for the past two months need to hook me up.

Two months is nowhere near long enough to be able to tell if you're doing longterm damage. My guess is that Intel most likely knows what they're talking about. Having the memory controller on-die changes things. The same thing applied to AMD's chips, when they were using DDR1, and people were burning out their memory controllers with high vDimm.

Sorry to revive my old thead. It seem the general rule is to have VTT and VDIMM within .5V of each other. I'm going to bite the bullet later today and try for 1.8V VDIMM with 1.4V VTT and see what that gets me. Wish me luck!

I went to 1.7 with my Corsair C9's, didn't net me anything, isn't stable above 200 BLCK, it's probably a mobo issue more than anything else.

If it runs fine doing this then I don't think it's all that "Xtreme".

Agreed. Why would ya go beyond Intels specs. for O/C. Get your 24/7 O/C and leave it. Thats the true performance of your PC. Anything else is xtreme fluff.

:roll:

By definition overclocking, even 1MHz above stock, is going "beyond Intels specs."

But yeah, my point was that going above the recommended safety limits is kinda crazy and more like something I'd expect to read about over at XS forums than here at AT.

Ya any over clock is out of spec unless intel does it. Turbo . I think intel has changed its stance on O/Cing. But raising voltage higher than Intels high limit isn't smart at all. Now after Nehalem has been out longer well get a better feel for what the true limits are. But I personnally I stay within Intels guidelines. If I melt a cpu . I don't try to RMA it either. Just not my way.

Right, the recommended safty limit. There has been more proof that by keeping VTT and VDIMM to within .5V of each other it can be considered safe. Anand said they would investigate this and write something up. I wonder what is taking them so long.
