I wouldn't be surprised if their response was right. The custom motherboard (I suspect it is custom) probably behaves "like it doesn't know what it's doing" because in the world of pre-builts it can afford to do so. People wouldn't be paying money in the "build it yourself" world if it couldn't handle something so simple.
Remove all old RAM sticks and install only the newly bought RAM and see if the system starts normally. If not, then the new RAM is bad.
the cr2032 battery keeps the cmos chip powered to keep the settings saved while the mobo is not powered by the psu
nothing to do with cpu or ram
rip i forgot what the battery was called lol
There is your problem.
Buy OEM Samsung RAM
Use only RAM that matches
Most likely the board only supports 4GB per dimm slot then.
Can you go to Dell.com/Support
Enter your Express Service Code in there to bring up your exact machine.
From there you can see things like that regarding the specs.
Maybe you are thinking back to the days of the very terrible BTX Intel systems with RDRAM
And I do remember some varients of Dell models that were meant to be low powered slim Desktops and because of this, Dell used some odd-ball design for the PSU plugs to where you couldn't just switch out and use standard ATX PSU. And I'm not talking about the BTX motherboards in that regard.
Best bet would be for the OP to share the specs.
This should be located within the Dell Support page for your Express Service Code; which brings up the exact system you ordered/purchased.
We could get the specs from SPECCY also; if the OP would like to Publish that. However when you copy that to clipboard. Use PasteBin.com to share it; as it will be alot of text.
What RAM you use in that Dell (as far as the DRAM frequency) should be dictated by the installed CPU. For example if you have a 10th Gen i7 or i9 then you want to use 2933 RAM.
You will not have any XMP profile options within Dell BIOS; you have to buy the RAM with the correct DRAM frequency if you wish to the BIOS to run it at the correct XMP profile, which it applies automatically as a default.
Which RAM you use though really shouldn't be a problem.
For DELL XPS and ALIENWARE models of Desktops and Laptops I've tried ones from Samsung, Kingston, Corsair, GSkill and they almost always have worked without any issues to speak of.
DELL usually comes with decent enough RAM regardless of which system you buy from them. So for example if you get an Alienware and it happens to have 1x 8GB DDR4-2666. Buying another 8GB DDR4-2666 (OEM Samsung) off Ebay should be enough to do what you want if your aim it to just step up to 16GB in Dual Channel.
It's been many years since I've opened a Dell and found anything inside besides OEM Samsung RAM. They just don't have heat-spreaders on them, no big deal.
HP tends to use cheaper Hynix based RAM though.
i tried upgrading ram and it basically exploded parts on new dimms, i think 128mb ddr 100 or 133mhz
it still booted with its orig ram tho
may have been me doing a stupid and putting a ddr 200 (100mhz) dimm in a ddr 400 (200mhz) build
one labeled at ddr speed the other labeled at freq
You could still mix RAM speeds back in those days. Just run at the speed of the slowest installed RAM. However motherboards were much more picky about RAM back then and most likely it would just not boot properly when doing such RAM mixing.
I personally don't remember ever having DDR1 below 333 and 400, but I do see via Wikipedia that 200 and 266 existed.
I remember having SDRAM at 100 and 133 MHZ on systems such as Pentium II 266/350/400
My first DDR1 system I think was Socket 754 w/ Athlon 64
A reliable motherboard that lasted about 10 years running WinXP all that time with a WD VelcoRatpor 300GB SATA HDD (originally had an 80GB IBM IDE HDD). Unfortunately the board had a bit of design flaw with only having 3 DIMM slots, with a max of 512MB per slot.
idono was a long time ago
A lot of the time, introductory speeds of a given generation overlapped the upper speed(s) of a previous generation.
DDR(1) started at 100 MHz and went up to 400 MHz. DDR2 started at 400 MHz and went up to 1066 MHz officially (400 MHz, 667 MHz, 800 MHz, and 1066 MHz being the range). DDR3 started at 800 MHz so it overlapped on 800 MHz and 1066 MHz.
The "sweet spots" were (to me) near the middle-end of each generation and were the speeds of 400 MHz, 800 MHz, and 1600 MHz for DDR, DDR2, and DDR3 respectively, and I guess with DDR4 you could call either 3,200 MHz or 3,600 MHz that (and guess we're looking at 6400 MHz+ being the sweet spot for DDR5 in a couple/few years?). The speeds above these tended to be "faster" or premium speeds and the ones below were just earlier speeds in a generational cycle. Again, merely IMO.
And while it was SDRAM rather than DDR (DDR-SDRAM), 66 MHz, 100 MHz, and 133 MHz were speeds for that, so DDR started by running the same top two speeds, but at DDR. 333 MHz was sort of an AMD only thing, as Intel's Pentium 4 used a quad-pumped FSB and those had FSB of 400 MHz, 533 MHz, and 800 MHz (they skipped 667 MHz) so divide those by four for the "matched" RAM for them. I think AMD used a doubled FSB.
