Formula Questions: PLX / SLI / Watercooling

Hey Guys,

I am considering purchasing my first ASUS board since a 2001 build using an AMD Athelon 1.3 Ghz. and I am looking hard at the MVF, but have a couple of questions before I hit the Submit Order button.

NOTES:
- I have downloaded and read the MVF manual.
- I typically water cool the CPU and graphics cards, as well as the mobo components if practical/necessary.
- This will be a CPU (3770k) / motherboard (?) / memory (Corsair Platinum) upgrade using two eVGA 680 Hydrocoppers.

QUESTION 1:

ROG Super Moderator TL@ASUS states in an earlier MV EXTREME thread that I can install one VGA card "to FIRST red PCIE slot (16x) or black PCIE slot (x8) to deactivate PLX chip". Can you guys please confirm that installing a single card in a FORMULA's PCIE_x16/X8_1 slot will definitely deactivate the PLX chip? Also, when I install that second 680 Hydrocopper in the PCIE_x8/X4_2 slot, will the PLX chip stay disabled so that I can run at x8/x8 without incurring PLX latency?

QUESTION 2:

How have the Z77 chipset temps been running on the Formula? Has anyone found the need to watercool this chipset? If so, I could you let me know which waterblock you used for that?

Along those same lines, has anyone recorded the temperature deltas of running water through the Fusion Thermo heat sink, versus on air? I would be helpful to know how hot the VRMs are running using both cooling methodologies.

Thanks, guys. I'm pretty sure that the MVF is the board for me, and if so I very much look forward to participating in the ROG community.

Hi, born2fli.
Welcome to the ROGs! In the time I´ve been on this forum I haven´t seen any posts on specific use and results on the Fusion Thermo yet, and I´ve found this "...This factor might be slight and not generally of concern to air coolers, but it still might make the difference for a few notches of BClk that means a world record or competition win for professionals." @ http://rog.asus.com/86722012/maximus-v-motherboards/maximus-v-formula-hybrid-thermal-solution-detail...
But, never the less, would be interesting to know how the temps. behave, and if some of the issues reported here could be alleviated by using the fusion thermo.

Thanks for the welcome, TenBlade. And for the link. I think I have a couple of 1/2" to 3/8" reducers so it wouldn't be difficult to water cool those VRMs. Prudence would suggest I see how the thermals on air work out in my case first, though.

Say, do you have any clue about those PLX chips in the Formula?

Very welcome, b2f, erhm, I have not clue whatsoever about PLX, haven´t heard of ´em until I saw your post. I´ll have to study on it now, dammit 😉

Oh, if you´re a fly-boy check out my user group, go Community/Groups in the top, look for Fly ROG AirWays.

TB, check out this link for a good jump start on PLX: http://www.anandtech.com/show/6170/four-multigpu-z77-boards-from-280350-plx-pex-8747-featuring-gigab...

Read down past the first couple of paragraphs...

And yeah, I'm certified SEL and MEL commercial instrument.

After watching a ton of JJ's vids, I am need to decide if ROG is what I need or just the channel line of P8Z77 boards. I am leaning ROG right now.

Thansk for the link, heavy reading :cool:

Well, my way to the ROGs went from the cpu recommended by other flight simmers. Then looking for a board, I stumbled across a video review by "Tiny" Tim Logan. I´ve followed his advice before, and hasn´t disappointed me yet. Relieved by the apparent ease of overclocking, I was even more convinced to go ROG again, after spending some time on this forum. I´ve learned so much here, and the patience of the tech wizards here is good! Just waiting to get all my stuff together for the build. And looking at all these slick builds, I must admit, that I´m going for the looks as well on this build, and the ROG board colours suit me just fine.

TB, are you thinking Extreme, Formula or Gene? Are you going to do SLI for your sims, and if so, which cards are you looking at?

I´ve got the Formula, to have the option for 2way sli, Extreme is too many bells and whistles aimed at hardcore clockers and benchers, and it comes at a somewhat higher price than the Formula.
The GTX 680 4 gb should be adequate for my four monitors (will need adaptors, I know), that´s 5040 x 1050 plus a 24 inch touch screen for instruments. Either MSI Twin Frozr or Gigabyte, important is they´re factory overclocked and come with dual or tri-fan cooling, hence less noise. Atm the Gigabyte is a lot cheaper than the MSI, the price of which has risen a lot over the course of autumn and christmas.

you have no issue with plx on Formula
the Maximus V Formula dont have PLX chip, able to run a sli w/o any issue
only Maximus V extreme have PLX for tri or quald sli/corssfire

AK47, right!? Actually, you can see the PLX chip on the Formula right between the lower two PCIe slots. It looks like the PLX 8606 chip, not the newer 8747 model: http://www.overclock3d.net/gfx/articles/2012/07/28095611400l.JPG
