Different Speed and rank and timing and voltage affect whether it works or not. There is a reason why most makers don't list density or timing etc. If they did you could match those parameters and test if the actual voltage and timing and rank for parts marked the same actually operate on the XMP profiles.
You cannot use different profiles on each slot nor is mixing vendors and speed supported.
Kingston trys to wiggle out legally with this statement.
All Kingston products are tested to meet our published specifications. Some motherboards or system configurations may not operate at the published HyperX memory speeds and timing settings. Kingston does not recommend that any user attempt to run their computers faster than the published speed. Overclocking or modifying your system timing may result in damage to computer components.
This is also from Kingston and has DIFFERENT TIMING
Well why dont you just buy the same Ram? Unless your MB can support even faster Ram you wont benefit much by going to the Vengeance. On my R8 that's what I did and the speeds didn't really change, I just ended up with more Ram lol.
And really if I watch my Ram usage I didn't even need more then 32
I ordered an Aurora R11 with the i9-1900KF processor, RTX 3090 GPU and 32GB of the HyperX Fury RAM running 2933MHZ figuring I could order a 128GB kit off of Amazon for $525 and save $375 since Dell was charging $900 for this option. I ordered the HyperX Fury 128GB 3200MHz DDR4 Ram CL16 DIMM (Kit of 2) Black Desktop Memory with low-profile heat spreader (HX432C16FB3K4/128) kit and installed it and couldn't get the system to boot. The Alienware power button kept flashing yellow 4 times indicating a RAM error. I backed off and could get the system to boot with one 32GB DIMM installed or two of them installed in slots 1 & 3 but that was it. I emailed HyperX support and after a few messages back and forth, they basically explained to me that the Dell HyperX 128GB kit has custom OEM CAS Latency timings that are slower than the retail kit I bought. When I asked them for the specs of the Dell memory, they said they couldn't tell me because that was considered Dell's intellectual property and that I should ask Dell. Right now, I am running the memory at stock settings at 2400mhz and looking for a way to play around with the memory timings to see if I can get around the XMP profiles set in my RAM kit so that they will work with my system. I know the Intel Z490 chipset can support higher speeds but what I am uncertain of is how much Dell has locked down the settings in the BIOS to prevent overclocking of the RAM besides the stock XMP settings that are baked into the RAM. I may try the Intel Extreme Tuning Utility to see what capabilities it will give me. I have yet to contact Dell support for help because I'm just stubborn. I will say that Dell has really watered down the aggressiveness of the Alienware line's overclocking capabilities probably to decrease the number of warranty claims from people getting too aggressive in the OC tuning and frying components. Wish me luck. @FinalTouch68

Hi @FinalTouch68 I am not sure you can actually buy the exact same ram, it is dell sepcific
