How crazy would it be if someone created a usb to ddr2/ddr3/ddr4 adapter?

i would be extremely interested to find out the performance, even though i don't think it's possible

It would be very crazy as there is no practical use that I can think of.  The RAM and the USB interface cancel out any benefits the other have.  RAM is designed to be very fast but more importantly low latency, and USB is not optimized for this.  Also anything you store to the RAM would of course be erased when power is lost, so there wouldn't really be any point.

Solve your own audio issues  |  First Steps with RPi 3  |  Humidity & Condensation  |  Sleep & Hibernation  |  Overclocking RAM  |  Making Backups  |  Displays  |  4K / 8K / 16K / etc.  |  Do I need 80+ Platinum?

If you can read this you're using the wrong theme.  You can change it at the bottom.

I agree, but a cheap placeholder for broken memory if you don't have any?, possibly install a really old version of ubuntu?

honestly, it would be like paging to a USB flash drive

Maybe a PCB with old DDR2 slots (with a battery backup and refresh chip) that you can use as an external RAM disk.

External ssd would be pretty much the same.

Why would you put DRAM through the slow USB interface...? And what for? You'd be better off using a USB SSD instead, even if it can't cache as quickly as RAM.

I mean as in, if you had memory that failed, and if the adaptor was cheap to buy, it could be an cheap and easy placeholder for the time

I meant for people like me who (for some reason) keep getting stuck with a ton of DDR2.

So basically just a holder for the dead memory?  Hm, I would just put it on the table, or in the garbage rather than into a USB device :P

so...
extrremly expensive memory that doesn't keep data when it looses power
capped at the speed of usb3.
or lower if you're using ddr2 n stuff.


why ?

A lot of ifs. With better solutions. A more useful device would be, for example ddr4 to ddr2.

Yeah, adapter that allows you to plug in older memory in newer systems. I dont know if thats possible though.

To be perfectly honest,

 

if your current memory fails, you're screwed. You're gonna have to go out and buy some more.

DDR2 to DDR3 or DDR4 would be nice. I have a shit ton of old DDR2 that I don't use. USB RAM is impossible and even if it was possible, it would be highly impractical.

There are 10 types of people in this world. Those that understand binary and those that don't.

Current Rig (Dominator II): 8GB Corsair Vengeance LPX DDR4 3133 C15, AMD Ryzen 3 1200 at 4GHz, Coolermaster MasterLiquid Lite 120, ASRock B450M Pro4, AMD R9 280X, 120GB TCSunBow SSD, 3TB Seagate ST3000DM001-9YN166 HSD, Corsair CX750M Grey Label, Windows 10 Pro, 2x CoolerMaster MasterFan Pro 120, Thermaltake Versa H18 Tempered Glass.

 

Previous Rig (Black Magic): 8GB DDR3 1600, AMD FX6300 OC'd to 4.5GHz, Zalman CNPS5X Performa, Asus M5A78L-M PLUS /USB3, GTX 950 SC (former, it blew my PCIe lane so now on mobo graphics which is Radeon HD 3000 Series), 1TB Samsung Spinpoint F3 7200RPM HDD, 3TB Seagate ST3000DM001-9YN166 HDD (secondary), Corsair CX750M, Windows 8.1 Pro, 2x 120mm Red LED fans, Deepcool SMARTER case

 

My secondary rig (The Oldie): 4GB DDR2 800, Intel Core 2 Duo E8400 @ 3GHz, Stock Dell Cooler, Foxconn 0RY007, AMD Radeon HD 5450, 250GB Samsung Spinpoint 7200RPM HDD, Antec HCG 400M 400W Semi Modular PSU, Windows 8.1 Pro, 80mm Cooler Master fan, Dell Inspiron 530 Case modded for better cable management. UPDATE: SPECS UPGRADED DUE TO CASEMOD, 8GB DDR2 800, AMD Phenom X4 9650, Zalman CNPS5X Performa, Biostar GF8200C M2+, AMD Radeon HD 7450 GDDR5 edition, Samsung Spinpoint 250GB 7200RPM HDD, Antec HCG 400M 400W Semi Modular PSU, Windows 8.1 Pro, 80mm Cooler Master fan, Dell Inspiron 530 Case modded for better cable management and support for non Dell boards.

 

Retired/Dead Rigs: The OG (retired) (First ever PC I used at 3 years old back in 2005) Current Specs: 2GB DDR2, Pentium M 770 @ 2.13GHz, 60GB IDE laptop HDD, ZorinOS 12 Ultimate x86. Originally 512mb DDR2, Pentium M 740 @ 1.73GHzm 60GB IDE laptop HDD and single boot XP Pro. The Craptop (dead), 2gb DDR3, Celeron n2840 @ 2.1GHz, 50GB eMMC chip, Windows 10 Pro. Nightrider (dead and cannibalized for Dominator II): Ryzen 3 1200, Gigabyte A320M HD2, 8GB DDR4, XFX Ghost Core Radeon HD 7770, 1TB Samsung Spinpoint F3 (2010), 3TB Seagate Barracuda, Corsair CX750M Green, Deepcool SMARTER, Windows 10 Home.

Even PCIe 3.0 wouldn't be able to keep up with RAM speeds.
