My First 4ghz Overclock (980x)

Running the Ram @ 2000Mhz with a Bclk of 200 normally does make the system unstable, I don't think a rampage 3 can run a high baseclock and high divider on the ram without very high Voltage like 1.7V for the memory, I would also make sure you have the QPI set to the lowest possible number in bio's, You can test the Ram stabilty using Intel Burn Test, I prefer this over Prime95 because it allows you to Test a CPU stabilty in 20 mins instead of 20 hours, But i run both anyway.
The other option is to set alot of the settings apart from the CPU volts to Auto, Then go look on CPUz Coretemp etc for the voltages, Then knock them down by 15%, It's a very fast way to find optimal settings for Low heat Overclocks.
I can't even remember what i had my 980X settings at when i had it on a Rampage 3, But it was at 4.5Ghz 24/7 on a H50 with pushpull Vipers, Never saw over 75 on anycore with 48 hours of prime 95, Maybe if you could go into the bio's and just take pictures of the entire screen and upload them we can check every possible setting, I would love yo help you get that chip to atleast 4.3Ghz.

Yeah it seams like it
Keep going down until you BSOD or get a worker error. If you get a worker error i would increase the QPI to 1.37V because there are allot of people that need 1.4+ QPI Volts at 2000Mhz to be stable. (your QPI is rather low for 2000Mhz memory imo.) You might be compensating your low QPI voltage with higher Vcore if you know what i mean. So don't be surprised if Workers start to fail when lowering Vcore.
Prime95 has been running for 1 hour now at 1.31vcore and QPI 1.35v
Should I keep lowering the Vcore, or should I up the QPI a bit?
Going to try and take some pictures of the bios
I recon you can lower Vcore more yes.
200BCLK should be easy for rampage 3. The X58 normally tops out around 225MHz BCLK. The only reason it would be unstable using a 200BCLK with x10 mem multi is:
A: You don't have sufficient QPI/VTT voltage.
B: you havent't got enough NB voltage.
If the memory is rated for 2000MHZ @ 1.65V you shouldn't need any more voltage as long as you are running rated timing too. It's the QPI/VTT that needs increasing to compensate for the higher BCLK

No you absolutely not damaging anything be lowering the volts as long as your OC is stable there's nothing wrong with "low" volts
And yes lower volts means lower temps.. Because power is calculated by multiplying the volts times the amperage so if you lower your volts you will lower your power consumption thus making your processor run cooler

If you're going to run the memory at 2005Mhz you should change the timings to 8-8-8-28 It'll help stabilty issues you're having then try prime95, Everything else looks Ok, I Normally i would be going through settings changing all sorts of stuff to manuel,But it's not possible to really do this over the forum, I personelly would run the memory around 1800ish, You won't see any performance difference in games or appz running from 1600 to 2000 anyways, Only at the higher 400-500 FPS, Which in 95% of games you'll never see.

I have just lowered the vcore again 1.28v QPI still 1.35v running Prime95 again
There isn't an option for 1800, the next one down from 2000mhz is 1600mhz...

Yeah your right Nat, but the stability issue hayley had was a IMC issue and not the memory itself. And it seams as your running stable now right? So i would leave RAM at 2005Mhz I see no reason to lower your speed as long as its stable. i would run at 2005Mhz 8-8-8-24 for now and if you run into problems later on change the 24 timing to 28 so 8-8-8-28 or even 8-9-8-28 if that wont help i would do as Nat suggested and lower the RAM speed

Yeah seams about right
lets just hope you can run prime for 60 min now then
(maybe a little on the high side but it wont damage your chip none the less, I think you can go lower on Vcore by increasing your QPI to 1.37v If you want to keep messing around with the settings that is?

What sort of vcore volts should they be on advantage?
I even have stuff downloading in background

Hmm.. hard to just give you a Vcore number as every chip is different, But i think you could go down to 1.25-1.27 Vcore maybe even lower hard to ques
