ASRock X99 Extreme11 LGA 2011-v3 doesn't getting start with 2 GPU

Pros: ... no Pros so far,

Cons: I was so exciting to buy this board just because about there functions, but all my dreams becomes a nightmare after have built this MOBO. First of all, the mobo not getting start with multi-GPU, even not with two hard drives. followed up the manual a saw that i needed to connection to power the fan on the heatsink shroud. A 4-Pin PEG connector seen near the USB 2.0. So far, i did, but nothing happing. After lots technician attempts i believe this is problem on PCIe Control.

Other Thoughts: Here's the parts that was built together the MOBO:

> Processor i7 6800k
> Memory Crucial Ballistix 16GB DDR4 2400 BLS16G4D240FSC
> Two(2) GPU's GTX 970
> Rosewill Valens-700, Valens Series 700W Power Supply, 80 PLUS Gold Certified, Single +12V Rail
> Corsair Hydro Series H100i GTX Extreme Performance Water / Liquid

This Board Will Waste Valuable Time and Money - Don't Buy

Pros: The good thing about this board is that is sells you on the many features that a power user may need and desire. The PEX 8747 feature allows for quad 16x lanes. This is a must for power users who use Quad SLI configurations or just enjoy Dual SLI and want 16x for other PCIEx devices. But I am not here to write about the pro's, because if you want this board, you have already researched the pro's. Now let's address the single egg rating. This is the important part of reviews.

Cons: I have used this board for almost 1 year. How many boards were RMA'ed? FIVE. The problems encountered?

The Cons
1. - Out of box no post - First board (Time To Failure?) Immediate out of box
2. - Multiple Memory Slot Failure - Second Board (Time To Failure?) 7 Weeks from first RMA above NEW Replacement not Refurb
3. - Complete POST Failure - Third Board (Time To Failure?) 16 Weeks from second RMA above NEW Replacement not Refurb
4. - Front side bus FIRE - Fourth Board (Time To Failure?) 4 Weeks from third RMA above NEW Replacement not Refurb
5. - Multiple Memory Slot Failure - Fifth Board (Time To Failure?) Immediate out of box

This is not an exaggeration. Read the other reviews. You will enjoy this board if you get a stable board. There is too much involved with having to change out board after board. The reason why I have not just switched vendors is that once you install all of your software Adobe suites, Windows and the LSI RAID card is not found on another board so far. We would loose data and config switching. So we just had faith that maybe just maybe we would get a solid board out of all this mess. Not ONE!

CUSTOMER SERVICE - Yet to Be Determined
All the previous RMA's we handled by NewEgg's awesome customer service. Now the Fire board is all on ASRock. We bought the Fifth board outright from NewEgg with more disgusting results. ASRock was contacted on 12/21/2016 - Currently waiting for an email reply from customer service. A complete business week has passed. Plenty of time for ASRock to respond. To date, nothing. I am comparing response time to NVdia or Dell's customer service. With the two, I received a response almost immediately give or take a day or two.

Other Thoughts: My Skill Level: 5 - Expert - Xavier Thomas - Linked In

My Confiuration:

Think twice before buying

Pros: Newegg is the best. Great customer service. Quick response to RMAs.
The motherboard has great features.

Cons: Had to RMA this motherboard twice. The first two gave me a d6 error, indicating that the motherboard could not see the video card. The third motherboard was unstable with the default bios settings, not letting me load the OS.

Other Thoughts: For the price of this motherboard, the quality control is very poor. The only way you should consider this, is If you can deal with the head aches. I should have looked closer the reviews of this product.

Dear Steven,

We sincerely apologize for any inconvenience this may have caused you.
For the unstable for load the OS, please try below,

Update to DOA board

Pros: Absolutely zero

Cons: Do not purchase this board unless you want an endless headache. I have built about 50 pc's in the last 5 years and never gone through anything like this.

I purchased one for a build I was doing for a customer. It arrived and on my test bench would not boot. At first I thought this was due to the significant warp in the board. Even the I/O shield would not line up correctly. I went through every troubleshooting step I could find and it was a no go. Being on a tight deadline I purchased a replacement with next day air and planned on reselling the first after it was RMA'ed. Another 2-3 hours of troubleshooting and come to realize it will also not boot. Keep in mind im $1500 in the hole for these boards at this point. With a replacement only return policy.

This motherboard only supports 16Gb memory modules on the latest 1.5 bios. INCLUDING the ones on the QVL. I happened to have a 16Gb stick of samsung server memory and a low end xeon that was on the QVL. It would not boot

I contacted asrock via phone 3 weeks ago and was assured I would have bios chips in my hand by then end of the week..... Still holding my breath. 2 more attempted contacts to asrock have failed in any response so far expect the generic we have received your support request.

I will have to purchase an 8Gb stick of ddr4 just to be able to resell these boards as used. Thanks asrock.

Other Thoughts: I have rma'ed boards in the past with both msi and asus. Both have gone well and eventually got good reviews from me. This experience has really been the worst from any manufacturer I have had.

I ended up going with an x99 deluxe. Came with the latest bios out of the box instead of the launch bios like asrock keeps shipping with, 5 versions out of date.

Dear Valued ASRock Customer,

We sincerely apologize for any inconvenience this may have caused you.
The mainboard supports 16GB ECC memory with E5 Xeon. Especially on QVL list.
However, we do glad to send the updated BIOS chip if its having compatible issue with memory.

The perfect RAID motherboard

Pros: Able to set 7 x RAID 1 arrays. Still 4 ports left of Intel chipset for other drives. Stable and practical, easy to set up. Motherboard is a work-horse when paired with 5960X. Easily brought 16GB CL15 Dominators (MD16GX4M4B3200C15) to 3200 MHz, and cpu to 4.2GHZ by changing the multiplier. Perfectly stable for work! Simple BIOS interface, easy to work with. Also, Asrock makes the best boards for WOL, unlike others.

Cons: LSI 3008 controller cannot be disabled on bios to skip POST, unlike the X79 Extreme 11 board. Annoying, but tolerable. 3008 controller is only capable of raid 0,1, 10, but for me RAID 1 is all I need.

Other Thoughts: I upgraded from the Asrock X79 Extreme 11 to this one, though the X79 has the same 3008 controller. I have a small medical billing business, and run my database, engine, and all shared drives from this PC. Due to separate environments, I have to run many raid arrays to accommodate separate environments to my clients. This board is just a beautiful combination of the X99 chipset and the LSI 3008 controller. I'm forever hooked to the Extreme boards!

Unbelievable!

Pros: None

Cons: Everything

Other Thoughts: I can't believe it. ASRock responded to my last review about the X99 Extreme11 by directing me to a cable that is rated to handle only 6 Gb/s bandwidth like that solves the problem.

The X99 Extreme11 is advertized as having a LSI SAS 3008 SCSI controller on board which is supposed to allow for 12 Gb/s bandwidth but the seven-pin SATA connector will only allow 6 Gb/s. The whole reason they are charging over 600.00 dollars for the MOBO is because of the LSI SAS 3008 SCSI controller on board which is obviously completely useless because of the seven-pin SATA connectors limited bandwidth.

There are NO SAS-3 cables on the market that have a SFF-8482 connector on one end and a seven-pin SATA connector on the other end that supports 12 GB/s bandwidth. It doesn’t exist.

YOU CAN'T MAKE THIS S*&T UP

Pros: NONE

Cons: SAS-3

Other Thoughts: The ASRock X99 Extreme11 advertizes itself as a MOBO that has 8 SAS-3 ports on it. However the SAS-3 ports are the same form factor as a seven-pin SATA connector. In the MOBO manual it states "For connecting SAS HDDs, please contact SAS data cable dealers" because ASRock does not include the SAS-3 cables necessary. So I contacted all the SAS-3 cable manufactures in the USA and they all said they have never heard of a SAS-3 cable that had a SFF-8482 connector on one end and a seven-pin SATA connector on the other end that supports 12 GB/s. So I e-mailed ASRock support and asked them if they knew where I could get a SAS-3 cable like this and they never responded. So I did a Google search to see if anyone was having the same problem and I found one other person that was.

At first I was extremely angry but after a few days I found this whole incident to be hilarious. I mean, can you imagine a company doing something like this. LOL!!!!!!!!!

I would never buy anything from ASRock ever again and I don't recommend anybody buying anything from them either. I will stick with and recommend to others more reputable brands like ASUS, Gigabyte, MSI etc.

Terrible board, Terrible Customer Service

Pros: Fast when it was booted

Cons: - Took 10-15 attempts to make it through the bootloader every reboot/start.
- Fast Boot / Ultra Fast boot just doesn't work.

Other Thoughts: Took a chance with ASRock, wish I hadn't.

After nothing but problems with this board, I contacted their tech support, who had me try one thing. After that failed, they then told me I had "a compatible problem" and I should return the board for a refund.

I won't be buying an ASRock again, nor would I recommend it.

I returned it and bought an ASUS.
