do the command thing i put in the OP! :)Wait, I have 2400MHz DDR4 ram, how do I know if I've not used them to their full extent?
I did some reading on this before enabling XMP and found that most common reason for crashes with XMP are when you may have RAM that is faster than what the motherboard or CPU can support. Does that sound like it might be the issue?
I had no idea either. D'oh!
Back in my day you just stuck the RAM in and that was that! *shakes fist at clouds*
For my MSI motherboard there are 2 A-XMP profiles. Did Profile 1 and now in CPU-z my DDR4-3600 shows as 1800 MHz. It does say that it is in Dual Channel mode, so not sure if there's still more I can do or what.
OHHHHH, well that makes more sense. Thanks for that info!
The easiest way is to check on the Task Manager.Wait, I have 2400MHz DDR4 ram, how do I know if I've not used them to their full extent?
A laptop is a computer so, I'd assume so! What's your laptop model, maybe I can help look into it with you?Do gaming laptops have XMP disabled? Or it doesn't come with it at all?
Dell Alienware 15 R4, 2019 model.A laptop is a computer so, I'd assume so! What's your laptop model, maybe I can help look into it with you?
Pretty much this.The kind of person who doesn't know to turn on XMP in their BIOS is also probably the same person who wouldnt notice a difference in performance regardless... honestly even people who know wouldnt notice a difference outside of benchmarks
Ok, I looked into it and discovered that this whole XMP thing began with the entry of DDR3 RAM around 2007-2009.
So basically if you, (like me and some others in here) started building PCs or modifying them earlier than those years, you're probably used to the default of RAM being an easy pop in, pop out kind of thing. So I guess it's a common mistake for people that have been building for quite awhile too!
Just checked the manual for your PC. https://dl.dell.com/topicspdf/alienware-15-r4_service-manual_en-us.pdf
these posts make me happy that I wrote this OP. :)Wooooow, OP, wooooow.....
Thanks man, I didn't know either! Lol
80 pins ide cables for maximum speed.
*slow clap*I've been working and building PCs since at least 1997, and I knew about all that stuff regarding XMP, dual channel, interleaving, SCSI, IDE... So many things that I picked up, and I haven't built a new PC in something like 5 years.
Ha! All you need to OC those is more RGB!Gosh dangit. I've been running my 2400MHz rams at 2133 for so many years now.
What else is there? Overclocking my mouse and keyboard!?
Holy fuck, I've built this PC back in 2017 and have been unknowingly utilizing the stock speed of 2133 MHz in my RAM since forever. Restarted, went into BIOS, turned on XMP, and lo and behold the RAM is at 3000 MHz now! Thanks, OP, for spreading awareness of this!
Just a question, though. Does this affect the lifespan or durability of the RAM in any way? If it becomes more susceptible to damage, I'd rather keep it at stock speed.
Nope it's fine. Your ram is now running as intended.Holy fuck, I've built this PC back in 2017 and have been unknowingly utilizing the stock speed of 2133 MHz in my RAM since forever.

I did that already and had to stop because artifacting would happen from time to time. Any idea how to troubleshoot that? I liked how smooth it was. I want to know if it's my monitor or driver or whatever?
You can check about everything on your PC specs and current configuration with Hwinfo.Wait, I have 2400MHz DDR4 ram, how do I know if I've not used them to their full extent?
Don't know if you got the answer to this already but most likely artifacting at 144hz is because of the cable you're using. Is it Display Port or HDMI? If it's HDMI then I would give it an almost 90% chance of being the cause.
If you're going to find a HDMI cable do some research about what's available and what will work for what you need because not all cables that are supposed to achieve a certain spec are created equal.
It's an HDMI cable. I don't know what type but I know what I'll do next time it happens. I'll hook it up to a different monitor with the same cable and if the issue follows, I'll blame the cable.

Alright, I'm good!
They were called jumpers because they jump out your hand and you spend 20 minutes looking for them on the floor
DDR memory is double data rate.For my MSI motherboard there are 2 A-XMP profiles. Did Profile 1 and now in CPU-z my DDR4-3600 shows as 1800 MHz. It does say that it is in Dual Channel mode, so not sure if there's still more I can do or what.
Dual channel is not the same thing as double data rate.
That's most likely to be a bad video cable.I did that already and had to stop because artifacting would happen from time to time. Any idea how to troubleshoot that? I liked how smooth it was. I want to know if it's my monitor or driver or whatever?
If you have a gaming mouse, make sure the polling rate is set to 1000Hz rather than 125Hz.Gosh dangit. I've been running my 2400MHz rams at 2133 for so many years now.
