I'm trying to get 128gb of ram to work on my PC. After installing 128gb of ram, my computer turns on, but I've noticed random shuts down. Thinking about the recent changes I've done to my PC, the only reason why the PC shuts down randomly is due to the recent added ram.
My motherboard is the Asus ROG Strix Z790-E Gaming Wifi. My ram is the G.Skill Trident 32gb 6000mhz CL-30-40-96 (I have 4x of them). And CPU is the i9-13900 (non-k).
I have no corrupted files according to doing a sfc scannow in cmd prompt. To get my 4 sticks to run I had to change the DRAM speed in BIOS to 4800 mhz from 6000 mhz.
What's the issue? Is there any other option I need to change in BIOS to get to run stable? Do I need to increase the VDD and VDDQ voltage?
If you just purchased the new RAM separately, they won't be from the same batch, so that's likely the issue. If you can still return them, then one option is to buy a matched set of 4 sticks. Make sure that your motherboard supports 4 sticks at that speed first though on the QVL list. Otherwise, you'll either have to run at lower speed or increase voltages within safe limits and see if you get lucky. There are many people here that know more than me about RAM, just my thoughts.
Hello and welcome,
Combining or mixing memory kits isn't supported by memory or motherboard vendors. This is because memory vendors bin and validate the memory kit in the density in which it is sold. If you combine memory kits the settings in which the kit is validated for XMP are no longer valid. You would need to return one or both of the memory kits and purchase a single kit validated for the density and frequency you are trying to run if one is available. Note that some frequencies are not possible in a four DIMM configuration, so best to stick to the QVL list.
See Intel's chart for DDR5 memory support on Raptorlake. Please note that frequency beyond what is noted here is considered an overclock depending on the configuration as outlined.
So just to clarify, I need to a 4 pack of 4x32gb ram (128gb total) to get the PC to work properly?
If I buy 2, 2 packs of 2x32 gb ram (128gb total) the pc won't work properly because the RAM isn't from the same batch? The ram I'm referring to is the same type of ram and part number, but sold separately as 2 packs.
The RAM I tested and installed on my system as said in my OP are the same ram and part number, but sold separately as 2 packs of 2x32gb.
But “batch” doesn’t fit right in this situation. Memory vendors bin memory kits in the density in which they are sold, as explained above. You can have two kits within 1 serial digit of one another and they would still have the same difficulty when combined.
The voltage, timings and frequency are tested and validated with two modules, in this case. Tuning these things manually can be very difficult without the right methodology or experience and there is only so much guidance one can give vicariously
