Tried without the SSD. Going to try disconnecting WiFi next with only one slot used
Followed the quick start guide to make sure I had no mistakes.
Still no luck with any assortment of RAM populated. Different post error with RAM empty.
I’ve submitted a support request, and will continue troubleshooting.
Crucial CT2K16G56C46S5
this is the same kit I bought. still waiting for my laptop to arrive.
has anyone else with this kit had success?
I believe so:
@Justin_Stackhouse, How’s the resistance in your memory slots? Particularly Channel 0?
The resistance is marginally lower in slot 0. Both have some resistance, but not much. Less than I’m used to in other laptops.
Sounds about the same.
You were right… The error code for no RAM is different.
Edit: I don’t know why Amazon is being so cool about it, but they are apparently going to allow me to return the kit. I’ll lose 20% for a restocking fee, but at least I won’t have to deal with selling them on eBay. Could be defective for all I know.
Edit 2: @Justin_Stackhouse, did you try killing all power to the mainboard (including the battery) for a little while? Didn’t occur to me until a few minutes ago. Doesn’t seem to have fixed the issue for me, but I would expect yours to work… Sorry that its not!
No luck on anything I tried. I am hopeful that the issue is the RAM, I’ll be near a micro center on Saturday visiting family so I’ll be able to try different options to get up and running.
I will say that I wish there were more public information on the POST codes in Framework’s documentation, but I guessing there are some restrictions from partners on this. Here’s hoping I get a quick resolution from support, ideally tomorrow, so I can enjoy this wonderful device.
Not quite sure what you mean by that, ram needs to have some jdec profiles, they just might not be the advertised ones if it’s an xmp kit.
I just mean that Kingston Fury Impact and I think one of the G Skill kits have more aggressive default timings than the standard JEDEC profile that they will attempt to boot into even without XMP enabled.
No they just got the better class A (40) JDEC timings instead of the more common class B(46) ones, still JDEC.
Anandtech has a nice table here.
Fair enough, point being the more aggressive profiles haven’t always played nicely with Framework in the past in certain SKUs.
That table looks nice, but isn’t completely accurate.
For example at 5600 MT/s that table indicates that the JEDEC classes are: A (40-40-40), B (46-46-46), and C (50-50-50).
Whereas this massive document from Micron states that the JEDEC classes at 5600 MT/s are: AN (40-40-40), B (46-45-45), BN (46-46-46), and C (50-49-49).
We can confirm that the Anandtech table is inaccurate because kits like the Crucial CT2K16G56C46S5 exist with 46-45-45 JEDEC timings, which wouldn’t be possible with the Anandtech table.
Interesting find
Weird, anadtech lists the literal jdec specification as a source but I am not sure how exactly those bins work (and I am not paying 400 bucks for the document XD), it may well be lower limits so anything between has to work for the memory controller anyway and the actual values are read from the spd.
The micron values are all still within the min/max from the anadtech JDEC values so I’d guess both are accurate. Micron B and C bins are just slightly better than absolutely required but I am just guessing at this point.
5600 CL40 is still a valid spec though be it from anandtecs interpretation of the jdec doc or from this micron datasheet.
I’ve had some back and forth with support that is continuing. My issue is an ongoing comedy of errors.
Firstly, 1 out of 2 of my Crucial CT2K16G56C46S5 is almost certainly bad, not working in any slot or combination.
Second, one of my issues is that the Memory Slot 0 QR code was askew and partially covering some pins on the MB. I only noticed this while getting pictures of the pins under the flaps to send for them to investigate. Very frustrating, and compounded with the RAM stick (not from Framework) being bad made it a nightmare.
For now I have a single channel memory laptop that is up and running and I’ll take it as a win.
Sounds like it’s ‘easier’ just to go with prebuilt and call it a day. The hassle of RAM compatibility and troubleshooting…not worth the dollars saved.
Errors happen, and any hardware can have issues. As a counterpoint, I got just the AMD mainboard to swap into an early batch 11th gen DIY laptop, and plugged in 2x16GB of the same CT2K16G56C46S5 and I have been running fine with no issues at all. That said, using the memory Framework sells on the marketplace or other sets they have tested on the board is the best way to make sure that compatibility is not an issue, and contacting support if you start seeing issues will help if your hardware is the problem.
I understand. Just saying that functional assurance has a price, and sometimes it’s worth paying.
However, if I face a RAM issue with a pre-built straight out of the gate, I would just return it. Pre-builts are supposed to be friction-less and hit the ground running. With DIY, sure, tinker with it till the end of time should one chooses to do so.
This ‘batch’ thing, into the 3rd year now, is IMO, at attempt to minimize returns…people don’t like to re-order in general (due to the wait time).
The “batch” thing helps a small company manage cash flow and inventory. They get some cash up front from deposits to reduce the cost of getting production started, and they have less guess work as to how many units to produce to meet initial demand. They don’t get stuck with a bunch of inventory, and then they can scale back on how much contracted assembly capacity they need to meet ongoing sales after launch.
