B7 error on Motherboard

[Callsign Zulu]

So I know B7 means a memory issue and I am pretty sure I figured the problem out... I got the wrong speed RAM 🙁.

My Mobo: http://www.superbiiz.com/detail.php?name=MB-X99WS&c=CJ

My RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E16820233794&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=

Is there a way just to lower the speed to like 2933? If there was I would be really happy, this is my first build and it is kinda really sucking so far. If I do need another kit will Newegg trade if I call costumer service or are they biggots?

IDK what I did wrong someone help please!?

The error code B7 can be quite a lot of things, are you sure you've run your memory with memtest86 for 10 passes to rule out that they are working? Have you tried populating the secondary slots with your kit and seeing if they work fine? Can you inspect if your CPU is making proper contact and that motherboard doesn't have bent pins? Is your BIOS up to date? They also should come with an XMP profile so you wouldn't need to manually set them in BIOS. You can also try and remove all your components and see if the system powers up with only one ram installed and later add the second corresponding stick into the corresponding DIMM slot and work your way up until your kit is populated.

To answer your question, yes, you can lower the frequency, timings and voltages in the BIOS. Regarding the support off of Newegg, they are usually the nicest of people though you'd need to call them up or initiate an email with them and request that you'd like to swap it with another kit though it'd need proper grounds for a swap.

It may also be a faulty motherboard with the slots or a bent CPU pin though troubleshooting will reveal if that is the culprit.

Do you have any USB or PCI-E storage devices plugged in? Nothing wrong with the DRAM compatibility wise - although if trying to run them at 3000 might need an OC of the CPU. Do you have the latest BIOS? Latest mobo drivers ?
