thank you so much for your help i really do appreciate it , i just want to know if the ram turns out to be hynix and qvl mentions samsung, then will it cause my system to be incompatible with the ram?
The QVL is just the ram kits the manufacturer has tested on the motherboard for compatibility. Every kit ram kit on the QVL still has a chance it won't work, even if the kit hasn't been changed to use different components. There are too many different kits to test and they only test them as kits. You won't find information on the QVL for mixing modules from different kits, which is why everyone says to buy ram as a kit and to not mix them for the best compatibility.
There is no real way to know if the ram kit will have a problem until you install it and it's more likely to work than not, so really you shouldn't worry about it. As an example, I bought two kits of the "same" ram for my motherboard and had to update the bios to the newest version at the time to get all four modules working properly.
If you buy the ram kit you want, the worst that will happen is the ram doesn't work at it's advertised spec without tweaking the settings or updating the bios. If it doesn't work at all you will need to return it for exchange with a different kit or a refund, so make sure you can at least be refunded before you make the purchase. The manufacturer might even honor a refund or exchange if the retailer won't, but don't count on that.
