So my R12 is designed to run like trash and bottleneck by my RAM. I can’t get any of my games to use over 50% cpu and GPU usage. It’s getting the same performance as my 7700k+1080ti. This is bad!
Could you help me find the best memory option for R12?
I've tried to read almost every page on this topic but I am just overwhelmed by all technical discussions and can't figure out what's the best option to upgrade memory. It was a big decision when I decided to spend thousands of dollars to buy an Alienware R12 (i7-11700KF, Liquid-cooling, RTX 3090, 32GB 2666mhz memory) for my son. I thought I can't go wrong with the Dell's latest Alienware machine but its PassMark score is similar to or a bit less than RTX 3080 of other pre-built machines. That's not what I wanted. I want to upgrade to a faster memory to see if that'll help even if that's not much. It's too late to return.
I've looked up all parts numbers you listed as validated parts for Dell R12 but none is available for purchase at this time. (Google shopping, Amazon, eBay, etc...)
I'd really appreciate it if you can help me find the best memory module I can actually buy on the market to get the best performance out of his R12.
Mine is currently in transit, but will be gutting it and transferring most of the components into a new case. So that means new motherboard. New PSU, and potentially a new liquid cooler (or just re use my existing one if possible).
Dell really the pooch here and I hoped that by the time I ordered mine to it arriving, they would have corrected it. But looks like that isn't going to happen.
2666 Mhz memory does not make sense. 3200 or 3400 Mhz would make more sense. If it is saying 2666 than you have not enabled the XMP profile in your bios settings.
Faster memory will not help with the issue you are experiencing, since the issue is related to the latency between the memory controller and the memory, not the speed of the memory itself.
There's nothing you can do about this as gear mode 1/2 is not supported on this system by design.
Others have tried faster memory, with no noticeably difference.
The best you could do is tweak the performance of your components, especially the CPU since it's a K variant and overclocking is available for that CPU. You already have 32 GB of memory, and I am assuming that is actually 2 x 16 in dual channel mode.
Agreed - my stock ram performance has been poor (R12, i7-11700KF). I've had some better performance using this ram - plug and play after you set XMP on from the BIOS: (3600MHz, CL16)
Can you run Userbenchmark and tell me what your latency is? Mine varies between 78-82ms with the stock 3200mhz RAM. If yours is lower I might consider buying
Big disappointment , as dell decided by design to save cost by providing hardware which could not could not fully support their feature .
as well as try to be ignorance when user are pointing out the issue . yet no other better solution as the memory speed forced to be gear 2 . I wish the company do all the best as well to their team .

I'd be okay with it if they just tested and certified up to like 4200mhz RAM on the R12 then the whole Gear 2 thing would be moot

Can you explain why the ram latency is sky high then? Will this ever get fixed? My system is not running the way It should because of this issue.

I just got my R12 3080 system and notice the high ram latency too, my dell XPA 3070 is outperforming a 3080 system…..very disappointing!

Ya, this is my first Alienware purchase. And sadly my last. Everyone online was right, “if you care about performance, you don’t buy Alienware.”
I waited too long hoping for a solution from them, but now I stuck with it or force to spend another $800 on new case and mobo.

what ram latency you get from these ram? My stock 3200mhz rams give me 80ms latency, which I is way too high.

i have the Corsair vengeance pro 3600mhz Kit and the latency is still in the lower 70s, you won't get lower than that because it the gear 2 mode

i mean when the motherboard is hard capping the RAM at 50% speed, there is no kit fastest enough to stop the RAM from bottleneck the whole system.

Hi @DELL-Chris M
