spent 6 hrs did a memtest, no issue found. Btw, the ram seems not really compatible with my mobo which is ASROCK C2750D4i.
When i power on server, the server will power off itself and then power on again. After that will run smoothly.

i guess i need to do a stress test like 24 hrs to see whether it is 100% backward compatible or not.

This will not fit desktop motherboards for lga 2011. This is the server model. This was not clear when purchasing the product. Currently siting unused in a box.

I bought two of them for a mother board that had duel sockets, I didn't  get it for the price I want. The cpus came in the mail actually earlier, I just can't say anything about install or anything.

This product came in a timely manner and getting it was not a problem. The board was recognized in the device manage, but the Hard drive was not. I tried several combinations of HD and external mounts but none were seen by the system. I tried a different board of this same type and got the same result. My conclusion is that my configuration will not accept additional esata ports. I can't fault this board or it's drivers. It just wouldn't work in  my case.

I have an ASUS M2N32 SLI Deluxe with a AMD processor running Win 7 / 64.

it would have been more ok if the product functioned correctly to begin with, however I can only surmise the product in question was not compatible with my system.

It's possible that I ordered the wrong part for my motherboard, because it wouldn't boot after I installed it.  I returned it and was promptly refunded by the seller.

Works with my picky Gigabyte motherboard in which other memories don't.

Not compatible with AM4 motherboards.  An adapter is available from the manufacturer, but shipping is another seven bucks.

Everything worked at installation except the USB 3.0 ports connected to the board itself. After installing all the necessary drivers and making sure the BIOS settings were correct, my USB 3.0 devices didn't work with the USB 3.0 ports. My USB 2.0 devices worked, though. I sent a refund request to the company page but they told me to contact my dealer, which I can't do unless I leave a review.

I hope ASRock sees this and can offer some solution to my problem. It's a great product, but this one tiny flaw has made it more inconvenient to own.

I bought this item, says a ASIX AX88179 chipset, but it is not, is Realtek chipset, it did not work on my Linux server that only accepts ASIX AX88179 chipset. I lost my time for this cause

I bought this,

hoping to reduce the temperatures on my core 2 duo extreme running in an evga 680i motherboard. The evga has a very large chipset heatsink which obstructs the freezone, not allowing me to install it correclty.

I attempted to contact the company (coolit) to see if anyone had installed on this motherboard, but received no response. I contacted the retailer I purchased this from, and was informed it could not be returned.

caveat emptor

Contrary to both Amazon and vendor's websites, this heatsink is not compatible with ITX form factor. It obstructs both A1 DIMM slot and M2 slot on my m/b (ASRock H170M-ITX/DL).
I have to return it.

Update on 01/02/2017: I got this CPU cooler (https://www.amazon.com/gp/product/B0177GTV9U) and it is fully compatible with my ITX board.

Works good but requires a special plug to connect to the motherboard. I had one but it was already in use. It would have been nice if it had a USB 3 connection to connect.

Although this says it is an LGA1155 socket type, it is absolutely not.  It is an LGA1150 and thus is not compatible with an 1155 mainboard. Use extreme caution and get the correct one for your mainboard.

This is too big for a standard Motherboard.  The capacitors are in the way.
