>>107496324retard. maybe learn something before you post. or just troon out and cut your dick off.
>>107496324Zoomers are so genuinely subhuman that I can't tell anymore if this post is bait or dead serious.
>>107496324You can use the four slots just fineIt's just neurotic gaymers have decided if they cant use a certain memory speed that the PC basically isn't worth using.
>>107496324For when you eventually need more ram.I.e a later upgrade.
>>107496341But that would slow down my PC
>>107496345>But that would slow down my PCIt doesn't matter at that point that's the drawback.
>>107496345You'd never notice it.
>>107496345>slow down my PChow many high-IO database clusters run on your PCs?if you don't know what this question even means, then it wont slow down your PC.
>>107496324You're supposed to turn on XMP/EXPO memory OC in BIOS to bring the speed back up. Memory controllers are designed to shit bricks and lower memory speed when you put in more than 2 sticks.
>>107496324we don't have the technology to run DDR5 in 4 slots, it's only 2025you shouldn't question it okay, we just don't. it's physically impossible
>>107496324Okay faggot you can stop flexing we get it you can afford ram. Fuck you.
>>107496369How many does EU5 have?
>>107496324For users who want to populate all DIMM slots you fool. You always take a hit on clockspeed and latency if you want to drive 4 UDIMMs. It is more obvious with DDR4 and DDR5.
>>107496454Yes, you can run 4xUDIMMs DDR5 on current platforms but you must take a hit on clockspeed and latency. The question becomes does the your use case need the extra capacity to justify the trade for reduced bandwidth and increased latency?
>>107496324retard alert
>>107496454>>we don't have the technology to run DDR5 in 4 slots, it's only 2025we do intel could since last year and now AM5 can too https://youtu.be/pA-R1FabTDY
DDR5 can't even run at its proper speed with 4 slots.
>>107496931This. I've had to deal with two DDR5 4xDIMM systems so far and neither of them were stable with fucking JEDEC speeds unless you cranked the voltage way the fuck up. DDR5 is a complete and total regression.
>>107496931>>107497008Laughing in DDR4 2666

>>107496737I have 4 Patriot a viper Steels B-Die on my Mobo = 32GB and I get 3800MHz out of them and the Max is 4400MHz. You're telling me if I dropped to 16GB I'll be able to do the full 4400MHz?
>>107496324Are my 4 slots running at 3596 considered full speed?
>>107498590Use HWInfo instead and show us the full window.
>>107496737I ran 4 sticks on my last DDR4 board just fine you just need literally any board/CPU that isn't fucking dogshit.
>>107496324It's only most AM5 CPUs that have complete utter fucking joke memory controllers. On my AM4 I could do 3600MHz with 2 sticks and 3200MHz with 4 sticks (all identical memory). I haven't tried yet if I can do 3400 or lower the timing to do 3600 because this is good enough, at 3200MHz I can use lower XMP timings as well.It makes the iGPU run 10% slower but oh well, hopefully they'll port Strix Point to AM5 soon enough so I can switch.
>>107496324imagine you needed more ram than 2 slots could offer, also its more complicated than that, motherboards have different topologies, and it changes the peak frequencies achievable,>daisy chain topologytraces connect to the first slot and then connect to the next one per channel ( most common) which behaves as you noticed, 2 slots can achieve higher frequencies than than 4 , can achieve higher frequencies than T topology, while retaining 4 slot capability, but sacrifices performance when using 4 slots> direct topologyself explanatory1 channel per slot, 2 slot boards , highest performance> T topologytraces are connected to each slot with roughly the same distance, this enables higher frequencies with 4 slots populated than daisy chain. a well designed T topology board can usually get pretty close to a daisy chain board with 4 single rank dimms, sometimes better , but depends on the platform( intel amd ect) quality of the motherboard, traces are longer than daisy chain , so usually max frequency is lower.relatively rare these days. much more common in the ddr3 and ddr2 era.capability of the memory controller also effects this to some degree.
>>107499363I'm on 2x SK Hynix sticks and 2x Micron DDR4 sticks and they seem to be running at full 3600 and timings look as advertised, right?
>>107496844>256gb of ddr5i already have a mortgage payment.
>>107499797>>107499500DDR4 is exempt from this problem because their CPUs came with good memory controllers. CPUs using DDR5 have dog shit MCUs.
>>107499845ok good to know I guess
>>107496324made me look
>>107496340>>107496780I bought an expensive new mobo and my PC still doesn't boot with 4 ram sticks. It's literally a scam unless you have a brand new expensive CPU + MOBO and you're willing to get shitty speeds
>>107499845it does apply to ddr4 above ~3800. so really only applies to intel platforms or zen2/3 apus.
