So, what are the "rules" with this new 980X?

So far, I see that rule #1 should be to never go over 1.4 VTT. Any other guidelines we should follow?

Maybe someone could start a list for a Sticky before people start overclocking in the same manner as they did with their 920's, and start frying their new cpus.

Something I can add to this discussion is, my current cpu is an Extreme Edition 975 (was current, I actually sold it today to make way for the 980), and I have tested both overclocking methods (Bclk vs. multi) and I saw no difference between the two at the same clock speeds, yet overclocking with mostly multi resulted in a much easier to achieve overclock, and a more stable overclock that didn't affect the other areas of the system as with increasing Bclk to a high level (180+).

Since high VTT is a bad idea with this cpu, I think I will be focusing my overclock on multi more than bclk which will only require a major increase on Vcore, for the most part, and will allow VTT to stay close to stock level.

Yep, you got it right, Focus more on Multi , QPI combinations with vcore voltage adjustments. and you'll be happy

Can we stop talking about VTT in terms of V, and instead with the + basis that is in the BIOS?
Would make things a heck of a lot easier.

For those of you that keep asking about the 980's voltage limits here is what Intel has posted. 

What Intel posts, and the "true" max are two different things. For instance, that table shows a Vcc max of 1.4, and there are people running 1.5+ for weeks now with no problems.

I agree, but don't various different motherboards and BIOS revisions have slightly different starting points for Vtt? At least when someone says 1.xV, there is no question what they mean.

Well said! Did you get your problem fixed?

expedision Well said! Did you get your problem fixed?

I have no clue bro. Tiger emailed me back saying my initial order didn't qualify, so I cancelled it and re-ordered (again going through the Bing website), and even used paypal to pay for it this time, but everything still looked the same, so I called Tiger's customer service, and the agent said that he could see where I used a third party site to place the order, and that it should qualify for Bing, but couldn't tell me anything more. He just suggested waiting until the order gets fully processed and see if Bing gives me the cash back. If they don't he said that they have no problem contacting their Bing rep. to sort it out for me, so I guess I just need to sit back and wait.

Basically +300 is 1.4v on the VTT if that makes it easier for ya.

Rockin thanks Firerx.
I asked with the danger of sounding uninformed, and in some ways I sure am. But I always figure that the dumbest question is the one never asked.
Especially with a gr. chip on its way.

Hey bro, I hope you didn't take my comment as a flame because I certainly didn't intend it to be. It's just that +200, +250, +300 can get kind of confusing when everyone isn't talking about the same starting point, you know?

Keep talking I am learning...

Thanks,

Sometime today I will start testing my 980X. I will be updating the template as it goes higheranis stable at that speed.

firerx , I have looked around, and made some P.M.'s to EVGA about the over 1.4 vtt killing the 980's. No such problem I was told. Same rule applys as other i7's. I know you said that your friends fried theirs. Are they SURE it was from too much vtt?

You mean only 1 stick installed?

Ahh, N.P.  LOL. Why are you testing it like that anyways?

 Here you go expedision . I don't know if this will help you, all settings are at stock with a fresh B batch (just installed). Like I said before LinX and the 980X do not play nice. When running 8 threads in LinX the CPU is only pushing about 63%. I hate to say it, but I've been using errrrrrr Prime.

 Has anyone running a stable 980X OC'ed for a few days. Then it's not stable anymore and it needs more vcore to be stable at the same OC it was before.

8 threads selected in LinX. 980X totally stock.


12 threads selected in LinX. 980X totally stock.

 I hear ya expedision, if people are posting BIOS templates (to show how far they made it) at least explain what method your using for stability testing (program and how long). IMO: Again, I'm not trusting LinX and that s**** because I really like LinX.
