H2+ RAM Slot issue

Post by falubux12 »

Hello,

I just received my new odroid h2+, and this RAM which was reported compatible:
G.SKILL Ripjaws Series 32GB (2 x 16GB) 260-Pin DDR4 SO-DIMM DDR4 2400 (PC4 19200) Laptop Memory Model F4-2400C16D-32GRS

However, I can only boot when a single stick is inserted. I tried both individually and they work, but they only work on 1 slot (the closest to the PCB).
I have updated the BIOS to the latest, but no luck.
Could it be the second slot itself being fault, or does this point to my RAM pick only working in single mode ?

The second slot itself could be at fault. You'd need a second H2 to confirm though.

If you believe the slot is fault, please contact "odroid at hardkernel dot com" with a URL of this thread.
They will help your RMA process if you purchased the device from our web-store directly.
Otherwise, contact your local distributor/reseller.

Sorry to bring the bad news, the 2666 Kingston HyperX RAM is known to be unstable, see viewtopic.php?p=265073#p265073
Please consider the known compatible table in the Wiki before buying: https://wiki.odroid.com/odroid-h2/hardware/ram

I have ordered ODROID-H2+. I have not saw supported RAM wiki page https://wiki.odroid.com/odroid-h2/hardware/ram and order 2x16GB RAM (Crucial 2x16GB CB16GS2666). It turned out this RAM not supported, wasted ~USD110 on RAM.

Please advertise in bold on product page that all RAM is not supported. I could had purchased RAM same time from hardkernel, now I need to pay ~USD35 in addition for courier.

Then I ordered for RAM Crucial (CT2K16G4SFD8266) but after a week vendor (amazon.in) is saying this RAM is taken out from market.

It's really tough to find appropriate RAM to start. I already spent about USD 250 on this device, excise duty and hard disk. Those RAM that I purchased is non refundable, what should I do with those unnecessary stocks of RAM.

Really sorry for the bad situation. :(
I've added a warning in bold to the product description.

On PCs the common assumption "faster specified RAM will just run slower, but its fine" does not apply to the H2?
The H2 seems to be often unhappy with 2666 RAM? But that's Intel's fault? ;-)

The good thing is, 2400 RAM can be had for cheap on the used market from upgraders, for 8GB 2400 I usually paid 15-20 EUR. Unfortunately this does not help when going for full 32GB :-/

We've tested Samsung 2133, 2400, 2666 and 3200 DDR4 modules and they worked fine at least.
2133 module worked at 2133 clock rate and others worked at 2400 clock rate.
So basically they are compatible.

I think we need to buy some incompatible Crucial modules to find any possible root causes.
