Yep. What I can say, as well, is that power consumption increases quite a bit when adding GPUs...over 50W/card in my system.


Did you test with one GPU, or a fully stuffed rig?

I was rather puzzled myself...what does IVB-E offer, then, right? I mean, I can clock my SB-E just as high... higher... and get only 20W more power consumed. But IVB-E is faster in benches and daily use to me.

Also note, Raja, my CPU will not boot AT ALL with "stock" regular LLC, and 100% VRM setting. I can't get boot until I set 140%. Whether that's because the BIOS is garbage, or my chip simply pulls tonnes of power... I dunno.


I also pull ~50-65W less when using 125 BCLK.


I am not using software to get these figures, either. I test every board I review like this, every chip, with physical meters in-line on 8-pin EPS and PCIe connectors, and the wall wart, which is something that like no one else does (or at least, they don't give such data in reviews).


It might be useful to you to know my board is not retail, has no serial number, and came in a box with SILVER METAL ROG logo. It behaves a bit differently than my retail sample, but only a bit in mem OC, which I thought was odd, since they are same revision, apparently. That said, guys here with retail have also needed the same VRM settings to end reboots...but you've mentioned power figures might need adjust.

That is a clamp meter on 12V EPS - so CPU power not rig power from wall or for GPU. Even at 1.40V I am under 200W..

How many VGAs? Don't forget PCIe is on CPU, using more PCIe increase CPU power consumption, not just board power.


I can't run over 1.35V without overheating, even with decent water. My chip has also been used under LN2 for about 40 hours.

I'm not saying that your numbers are wrong...just that these CPUs are quite varied in quality. My three samples...wow...one does 4.2 only, the next 4.3....the third, goes sky-high, but only 4.7 on water @ 1/35V, and then it's almost at throttle under P95.

Even with 2x I dont get what you are under full CPU load. PCIe side controller on CPU is not that power hungry, transceivers are at high impedance for this stuff. They don't pull 40W per GPU added from CPU~PCIe controller die.

Maybe PCie is where my CPU sucks.


On the same thought, however, this board will not boot my 3960X C1 (C0 worked fine) with x16 slots 1/3 populated. Another user had similar problem, but with different slots. Could be a problem with my board, dunno. Beyond my scope.

I mean...I don't care, really. That is just my experience with these chips. My P9X79 Deluxe clocks 8 GB ram sticks better, too, but this board is supposed to be tuned for ram clocking. Oh well.

wallwart pic (system at stock, ie, optimized defaults loaded, wireless/Bluetooth/eSATA disabled, 4960X, 4x4 GB Dominator Platinum 2666 C10 @ JEDEC 1333 C9, 2x GTX780 Ti ASUS reference):




I have an H90, 3x air penetrator, one noctua fan, one Crucial 128 GB SSD, 2 mechanical HDD, + two of the stock white LED fans from CARBIDE 540 AIR, and a NZXT Sentry Mesh. All powered via Thermaltake ToughPower Platinum 1275W


With that list of parts, you are right, power consumption should not be as high as it is...but my VGAs also exceed TDP at stock, and throttle like mad. I'll be RMAing these $800 cards, both, real soon.

The only real change from the ES boards were to retail were some DRAM trace refinements. My board here is one I purchased retail.

Yeah, what can I say, really? With CPU board and technically mems all being ES... Not much.

That said, stock, my rig shuts down, reboots, does other weird stuff...but on OC...it's a tank. Under LN2...amazing. Efficiency is pretty good, too. I gave the board a good review, after all - I don't give Editor's Choice award lightly.

That said, the one I am using...has some issues. tongue.gif I probably caused them with the LN2 runs.


It is also possible my board is grounding out internally somewhere. Like I cannot discount the real possibility that I really damaged it, and the issues that I am left with are due to that. The LAN thing is rather odd, after all..why do I need warm boot for it to work? OH, and the Intel MEI driver won't load either, and yes, I've reflashed BIOSes.


I have many ASUS ROG boards sitting here with what I think is corrupt MEI...we've talked about this before on XS with 1155 boards, you might remember. I have one MAXIMUS V EXTREME and one MAXIMUS VI EXTREME, both lost audio on a reboot when clocking ram.( Same thing, run SPi32M, Spi fails near end of test (20-23 pass), I shut down to change timing in BIOS, reboot, audio is now dead)


I push my hardware HARDER than anyone else, really. I do try to break things when pushing for reviews.

The 0602 build should cure the shutdowns you are getting at the lower overclocks even on ES board I think.


If you have a clamp meter for the EPS 12V and it is seeing substantially more than 200W at 4.5GHz with 1.25Vcore under full CPU load, then something is amiss.

When I measured board power without GFX card it took 68W, with GFX card it took 82W. GTX 660. Also Cadaveca can you look if you have PCI-E 3.0 active? I was forced to mod registers to activate it.

Works fine for me. I am using IVB-E now, so no problems there. IF you installed OS with SB-E, then upgraded, I'd suggest looking at OS as a fault cause. If you have SB-E only, then yes, AFAIK, "hack" is required.

I have had one PSU and two SSDs die with this board so far, so I have fresh OS that is only a week old right now. I haven't even played games yet really...I have way too many reviews in backlog. This hobby of mine takes up too much time! tongue.gif


Anyway, screenshot for you:

Yeah, but I'm stable.. so...

I just wanted to point out...this high power consumption is possible. My poopy chips...pull 180W @ 4.2/4.3, before I gave up on them. I was really hoping for 4.6 under 165W, honestly. I just think that some users may push chips in such a way that degradation to this point is most definitely possible.

I'll give the 0602 a try once I get this work done and get it backed up properly...and report back about it afterwords.
