CRC errors hyper x beast 2400 16 kit (2x8)

[naameh2002]

hello community
i would like to hear some expert thoughts regarding a problem am facing.
i build my rig recently and i used the best parts i could offer(witch cost a lot here in my country) so i was expecting some serious performance.
my setup is:
Intel® Core™ i7-4790 Processor (8M Cache, up to 4.00 GHz)
Asus Intel Z97-P ATX Motherboard
Kingston SSDNow V300 Series 2.5" 240GB SATA III Internal Solid State Drive (SSD)
ASUS GeForce GTX 980 STRIX-GTX980-DC2OC-4GD5 4GB
HyperX Beast 16GB (2x8GB) PC3-19200C11 2400MHz Dual Channel Kit (HX324C11T3K2/16)

I used to have a normal 8gigs 1333 ddr3 from my old pc but when I installed my new graphic card it showed only pci express 2 so I had to change the ram to solve this issue.

So I bought the hyperx beast and setup XMP profile in the bios to run at 2400MHz.
Since then (2-3 weeks ago) I had 4 BSOD and many CRC error when installing games or large programs from disks (couldn’t complete any installion). I didn’t know what caused this so I did some researched and found that its ram related issue.
Trying to solve this I ran some memory Diagnostics like the windows built in mdsched.exe tool, HCI memtest tool and MemTest86 all test completed without any error but the CRC errors didn’t stop until I disabled XMP from the bios.

Now am confused is it the motherboard or the memory kit or is it something else?
I paid a lot for this kit (it cost 160$ here) and I want to use its full speed not like a normal 1600MHz one.
Again I would like to hear what the community thinks about this and thanks in advance.

Like with most things when you over clock them you are asking the memory to work harder.
XMP is basically a pre configured setting to over clock memory.

But as said when you over clock memory it is required to work harder.
But it also requires more voltage to keep it stable.

You will notice that if you disable Xmp mode of the memory in the bios the voltage of the memory is reduced to about 1.5v to 1.55v and when Xmp mode is enabled the voltage will read about 1.65v.

But sometimes either due to the motherboard the voltage is slightly off set.

If memory fails or produces errors, the answer is to manually increase the voltage supplied to the memory.
In some cases an increase of just 0.250Mv is enough to stabilize memory so the Crc errors go away.

Intel motherboards do not natively support that high of a memory frequency. If you look at your motherboard's sale page

http://www.newegg.com/Product/Product.aspx?Item=N82E16813132229

you can see that many of the frequencies are labeled "OC". Just like any other overclock you don't have a 100% chance of getting it.

make sure the mb has the newest bios so it has the newest ram and cpu code.

hello and thanks for reply.
yes i do have the latest bios. and based on the info Shaun and thor provided it seems that my problem is the motherboard ?
on kingstone site they mentioned that each unit-kit is tested so i assume if i changed the board my problem will be solved?

make sure the dram voltage for the ram is not set to 1.5v it to low for those ram sticks. needs to ne set to 1.65 per asus tested memory guild for your mb.

when i disable XMP profile the voltage is set to 1.5v
XMP profile #1 dram at 2400MHz voltage is 1.65
XMP profile #2 dram at 2133MHz voltage is 1.60
i tried profile #2 and sometimes it works and sometimes i get the same CRC errors
i am very confused here this board should handle 2400MHz as asus claim and i do have the latest bios version
and my cpu can handle this type of speed right?

have you tried one dimm in slot a0 and see if the crc errors are there. then swap the other in and see if one of the dimms are bad?? also ram on asus slotted as a0 and b0. then a1 and b1. make sure the ram is in those slots if the 0 slots have crc try the a1 and b1 if they error out if may be your cpu and not the mb. the memory controller is now built into the cpu not the mb.

i tried that and the problem still the same 1 stick in a1 - b1 - a2 - b2 and both sticks in b1-b2 and it didnt change
and when am done now the crc error came up even when XMP is disabled 🙁
