XMP profile issues

[montrey]

Hey guys,

I've recently bought my first time ever gaming PC and just yesterday decided to also buy some additional memory, as I have been told it might help with some games.

As this is connected mainly with ram and (I'm guessing) the motherboard, here are the specifications:

Motherboard: MSI Gaming 970
Memory: 2 x Kingston FURY Memory Red - 4GB Module - DDR3 1600MHz CL10 DIMM ( product code HX316C10FR/4 )

I've set the memory on the XMP 2, the speed going up to 2133Mhz as the motherboard allowed it.
All was well, it worked fine.

Yesteday, I've bought Beast - 8GB Kit* (2x4GB) - DDR3 1600MHz Intel XMP CL9 DIMM ( KHX16C9T3K2/8X ) and added them to the system.

I had previously set the xmp profile to 2133Mhz, and after adding new sticks, bios would not boot up and it will not boot when setting xmp. If I set the speed to 1600Mhz, all of them work well.

Now, my question is, can I somehow set the bios so they can work together in xmp 2133Mhz?
Is it even worth it? I mean, there has to be some kind of conflict between them right?

I would appreciate some insight into that, I need to know if there's even a need for those additonal 8gbytes. Thanks in advance

Both your ram old and new are rated at 1600Mhz and this is the speed you should be safely be using them on. Overclocking those all the way to 2133Mhz obviously causing issues.
Just ram them at 1600Mhz no noticable performance for gaming anyway.

But isn't the XMP profile kind of "automatic safe overclocking"? Besides, when using the old sticks it wasn't causing any problems.

No, if your ram is rated at 1600Mhz it means this is it's factory safe limit. Xmp does not magic it just stires preset profiles for all sort of oc'd ram.
Maybe you got ucky with your old ram and it was good overclocker. Plus with all 4 slots filled up all of the ram gets much hotter now I would imagine.
Just run it at 1600 man

Thanks for your answer.
If I could just bug you with one more question:
Can't a GPU benefit from more ram?

 

[mp5mafia]

No problem.
And no, in your case it won't benefit your gpu.
It's only a case with integrated intel graphic cards where they use your system ram.
Your msi gtx 970 has it's own ddr5 vram to work with.

However because you only had 4GB before you most likely was running low on ram while gaming and it was slowing all down as it had to use your hdd/ssd to back it up.
Now with 8GB you good to go just run it at factory 1600Mhz please
