[SOLVED] RAM problem? Games and apps closing after upgrade to ultrawide monitor

Hello, since i switched my monitor to a ultrawide (LG 29wk500P) my PC started to have some wierd behaviours.
When I'm playing games like Assassin's Creed Origins or GTAV, as the moment that the game loads it closes by itself.
Another times, I'm in the middle of the game I minimize it and open the google chrome and it closes the google chrome.
I suspect thatit has something to do with my RAM.

Can anyone help me please?

My pc specs are:
RAM: 2 x HyperX Predator 8 GB (DDR4, 3000 MHz, CL15, DIMM XMP, HX430C15PB3/8)
MOBO: Asus ROG Crosshair VII Hero
NVMe: SSD M.2 2280 Samsung 970 Evo Plus 250GB MLC V-NAND NVMe (OS)
SSD: SSD 2.5" Samsung 860 QVO 1TB MLC V-NAND SATA (GAMES)
CPU: Ryzen 2700x;
Cooler: Enermax Liqfusion 360 mm
GPU: Evga GeForce RTX 2070 XC Ultra
PSU: Evga SuperNova 850 G3, 80 Plus Gold 850W
 
Hi neurso:)


The most common cause of what you describe is indeed bad ram. First thing to do is to determine if indeed your ram is stable and free of errors. Run Memtest86 from a USB for 2-3 passes to eliminate that possibility. If there are errors then RMA..
If indeed you have 2 individual 8GB kits then an issue or latency mismatch may exist and manufacturers warn of this. Best is a single kit 2x8 that are factory matched.
Go here to download your QVL and check that your ram is listed and tested: https://www.asus.com/Motherboards/ROG-CROSSHAIR-VII-HERO/HelpDesk_QVL/

Ryzen is picky so if you continue to have issues then see if you can return what you have. I can recommend a good 16GB Kit that work well with the 2700x CPU if you wish.

Hello MeanMachine41!

Thank you for your fast reply.
I did as you said and I got no erros on the Memtest86.
I'm was certain that the last time that I checked that list my rams were there :D but maybe I ordered the wrong ones by mistake.

Can you please recommend me a good 16GB kit for my PC?

Best regards

Memory modules sold as Single modules have no guarantee to be compatible in any configuration other than as a Single module. There are no guarantees that two of them would be compatible together, but you can do your own compatibility testing with no guarantees.
 
Yes the Ripjaws would be an excellent choice. Just bear in mind that they are OC RAM and will default to a lower frequency than their rated frequency at first boot. You will need to manually set their rated SPD in Bios as I don't think there is an XMP profile for 3200MHz. You can obtain the primary timings and voltage from within Bios in the Tools section or from CPUz in Windows.
I myself have GSkill F4-3200C14D-16GTZR which are RGB modules. (more expensive for RGB)

Hello again, i checked again and the ones that i have are listed actually. I was seeing the 3rd generation ryzen file and not the 2nd (https://dlcdnets.asus.com/pub/ASUS/mb/SocketAM4/ROG_CROSSHAIR-VII-HERO/C7H-Memory-QVL-Ryzen-2nd-Generation-Processors.pdf ), are this ones better for me? https://www.amazon.com/G-Skill-TridentZ-16GB-25600-F4-3200C16D-16GTZR/dp/B01MTDEYHU

Can you recomnend the best ones for me from that list?

As Calvin7 explained your combination of two single modules has no guarantee to work together.
Most have found that RAM modules with B-Die chips are best and work well with Ryzen.
Here is the B-Die finder list: https://benzhaomin.github.io/bdiefinder/

You have slightly better performance with CAS 14D than 16D but not by much. Both should work fine.
It is also advised to update your Bios to the latest version. Simply done using your rear IO panel and a USB stick.
