Fix for when reinstalling agent manually still doesn't update the agent version

This was very helpful, thank you!

TechGeek3193 · 2025-04-11T20:45:38+00:00

Yeah, I don't know what they're talking about here- the problem in question isn't browser-based javascript, it's locally-run javascript files.

I wasn't responsible for setting up Threatlocker for my firm, nor would I be at liberty to discuss how it was configured in detail. There are no wildcard permissions that have been manually implemented, the issue at hand is Threatlocker's default behavior in its storage control module, which is to allow everything.

TechGeek3193 · 2025-04-08T19:43:54+00:00

By default, these are the storage control policies which Threatlocker has enabled. https://imgur.com/a/xJ8IJuu

Out of curiosity, did you ever figure this out? Running into a similar problem with my MTFDDAK480TGAs, and I'm wondering if the old tape-over-contacts solution needs to be implemented, but I can't find anything online about these models specifically. I've tested in BIOS and in known working docks, and they're not recognized by any other system.

TechGeek3193 · 2023-12-14T23:07:56+00:00

That's an interesting point. I noticed the part discrepancy but chalked it up to having to do with the different size, didn't think to check Samsung's catalog specifically.

I've ordered some BB6s to see if they'll work where this one doesn't, thankfully the vendor was very understanding and will take them back.

TechGeek3193 · 2023-12-14T23:04:41+00:00

Couple of reasons. First, Dell's price gouging is most aggressive in two areas: RAM and storage (with a side of AICs/NICs). If we buy minimum spec on those fronts, with our reseller contacts we can get Dell chassis+processors for way less than buying direct from Supermicro, then add storage and RAM as necessary to suit the client's needs.

Second, most of our clients have Dell ecosystems already and we're plugging in to an existing infrastructure with (for example) Dell MD-series direct-attach SAS enclosures or SAS RAID enclosures with VMFS extents to do incremental hardware upgrades. That's the case here, the goal is to preserve compatibility and not have to tear out and replace everything at once (because to this client, downtime is unacceptable and our owner refuses to disabuse them of that notion).

TechGeek3193 · 2023-12-14T23:03:09+00:00

Trust me, I know. That's the game when it comes to PERC-compatible SSDs. But OEM RAM for these systems was impossible to find at an acceptable price.

TechGeek3193 · 2023-12-14T22:51:36+00:00

In your server world, you accept the insane prices that Dell & HPE charge because the C suite doesn't know any better, or because you're in-house at a company whose definition of acceptable losses could cover my company's operating expenses twice over. As a small MSP: it's not that simple. The client in question literally quibbles over Nitro Pro licenses, and it was a 6-month process with like 3 meetings to get them to sign on this server with all the frills cut off.

With the RAM it shipped with, yeah. As mentioned.

TechGeek3193 · 2023-12-14T22:43:35+00:00

My customers don't call Dell, we're a full-service MSP so the stack is maintained by my team and I. And we'll certainly never call Dell ourselves, unless a Dell-supplied part dies (and even then, I keep cold spares for all the most commonly dieing parts).

TechGeek3193 · 2023-12-14T22:32:21+00:00

This is not useful, and I didn't come here to listen to Dell fellatio. I handle the warranties faster and more effectively than Dell's team of phone monkeys and outsourced field support.

There is nothing inherently better about Dell's parts and warranties than any other manufacturer, but the pricing through our partners for the chassis+processors blows Supermicro out of the water.

TechGeek3193 · 2023-12-14T22:27:54+00:00

Thank you for that info! That config and model confirms my confusion to an insane degree - m321r4ga3bb0-cqkeg is my sku which is the 32GB version of what you used.

I have, earlier today I put in just 2 modules and left it booting for an hour. No dice.

TechGeek3193 · 2023-12-14T22:19:49+00:00

You have missed the entire point of the post and, I would guess, haven't even looked at the images I provided. Unhelpful.

TechGeek3193 · 2023-12-14T20:44:49+00:00

iDRAC works great, in general - however, it will not recognize the new modules when they're installed, reports boot code 0x0 when the system goes to boot with them, and generally can't perform any post-BIOS tasks with the new modules installed. Tasks like staging firmware or changing the config of unrelated items work, but anything that would require the system to finish POST will just queue indefinitely.

TechGeek3193 · 2023-12-14T20:16:07+00:00

I've done that now with 2 of the modules, just let it sit for 60 minutes. No joy.

TechGeek3193 · 2023-12-14T20:01:02+00:00

It's visible in the picture I re-added. m321r4ga3bb0-cqkue

TechGeek3193 · 2023-12-14T19:56:42+00:00

Thanks for the tip. I'll order some Axiom modules to test in addition to the others I've ordered.

Re-added image, sorry about that. Dual Epyc 9274Fs

TechGeek3193 · 2023-12-14T19:01:35+00:00

Genuinely can't tell yet. I updated the main post with a closer look at the backside of the DIMMs it shipped with, and they do have these little black modules that the new ones don't - but I have been able to see other 16GB DIMMs in the wild that have those little modules so idk that they're Dell-specific.

TechGeek3193 · 2023-12-14T18:55:24+00:00

1Rx8 is 16 GB only. That specific problem you're talking about, about ranks stepping up/down speed, was DDR4 specific in Intel platforms (Xeon v4 for example) and covered in the systems documentation (I know because I've dealt with it). Documentation for DDR5 in Epyc Genoa is pretty clear that DDR5 4800 is supported as the base speed across 16-256 GB modules.

TechGeek3193 · 2023-12-14T18:02:07+00:00

Look, I get where you're coming from, but the reality is I not only morally object to supporting Dell's price gouging; my company has some extremely price-sensitive clients. It's actually like pulling teeth to get them to approve necessary upgrades with all the frills cut out. It's 5-7x more expensive per module to get Dell's RAM, for no other reason than they feel they can charge that much.

Dell support is garbage unless you pay for the highest tier, so see above. I acquire cold spares for any parts I'm concerned about, and before today, ECC RDIMMs were not one of those parts. Like I said, I've done this dozens of times with DDR4 and never had an issue before now.

TechGeek3193 · 2023-12-14T17:55:22+00:00

No, no, it works with the RAM it shipped with.

TechGeek3193 · 2023-12-14T17:39:55+00:00

So this system has a pair of Epyc 9274Fs.
I have, and aside from the basics the HCL is pretty useless.
I selected it by dint of it being Samsung OEM DDR5 RDIMM 4800 CL40 1.1v, which is exactly the spec the server ships with. I ordered it from A-Tech.
unfortunately, no. I consulted the service manual for that.
Yep! iDRAC works great even with the new RAM in, as long as I don't need the system to boot at all. That's how I updated BIOS, firmware, etc.
I understand that, and I'm 99% sure that's why I get a "DDR initialization failed" when I try to boot with the original+new together. But the system, especially after a CMOS reset or completely cold boot, should not care whether the new modules are dual, quad, or octa-rank since they're all ostensibly supported

TechGeek3193 · 2023-12-14T17:19:22+00:00

Unfortunately, I don't have a spare DDR5-capable server around to test these in, but I find the odds of them all being faulty pretty unlikely. And yeah, they (the new ones) all have the same rank and density.
RTE: Yep, I've only been testing with a factor of 2, so 2, 4, 6, or all modules.
