Solved Computer wont boot with new RAM

February 5, 2019 at 07:07:32
Specs: Windows 10
I have a Dell Precision Tower 5810 (piece of crap i know)

I recently bought some new RAM to upgrade, however when I install the new sticks, the computer refuses to boot.

I have tried booting with only one stick of the original ram at a time, then with a stick of the old ram to the same result each time.

The power turns on, but I get no beeps, no video signal,

The computer boots fine with the old RAM installed again though.

The new RAM in question is TIMETEC 16gb DDR4 2133 CL15 1.2V 2Rx8

I had contacted Dell before purchasing the RAM and they said that it would support DDR4 though they recommended against third party RAM as they wanted to sell me their ludicrously expensive Dell RAM at 3x the price.

Im not sure whats wrong? Are these sticks just incompatable? As Im sure this comp can handle up to 256GB of RAM at a time, though Im not sure what each slots Maximum is for a stick.

So any help or advice would be greatly appreciated.

According to the Dell Manaul, to run a total of 16GB RAM, it should be 4 x 4GB. See page 36:

Or see the memory chart in the Dell forum:

Maybe you need to put in at least 2 RAM sticks, to get it to work.

Read more about this in the users manual of your computer.

Mostly you can put in 2, 4, 6 or 8 sticks.

For your computer, I don't know it for sure.
There is no description about that in the manual, downloaded direktly from Dell.

if it works with the old ram installed, suggest running the Crucial Memory Scan
which advises which memory is suitable for the device.

Maybe if you are mixing old and new there may be a problem.
Also the amount of memory you quote (16gb or 256 gb) seems high.

Good Luck - Keep us posted.

I tried initially with both new ram sticks with the old ones removed.
Then i tried each new ram stick individually,
then tried to run it with a new stick and an old stick.

All produced the same result.

The 256GB i quoted is the maximum possible RAM for the computer. I ran the crucial memory scan before and it has suggested compatible RAM. However they are much more expensive for the same amount of space.

If possible I'd like to find a way to make these sticks work before sending them back and getting more. These are work computers for the company i'm employed by and we already had to send some other RAM back.

After Dell told us that these would be compatible, I am loathe to return to my boss and tell him we have to send another set back and pay more :S

Your Dell workstations require registered memory. The cheap stuff that you have bought is almost certainly unregistered.

Crucial memory is normally pretty price competitive, and is guaranteed to work with your computer. It is more expensive than the RAM that you have bought because all registered memory is more expensive. That's just the way it is.

In business, time is money. Stop wasting both and buy your RAM from a reputable supplier like Crucial (or Dell themselves) who will supply RAM of the correct specifications for your computer.

I agree re' using Crucial to scan, determine, and recommend which RAM to use. I have yet to find their advice anything but spot on - be it for PC or Mac systems. Crucial are my first (only...) port of call for RAM.

Often they aren't that much more expensive than some of the "other" sources... Compare Crucial against Dell of course and see which the company budget will allow?

No worthwhile (or otherwise...) company can really afford to opt for cheap IT resources; especially RAM, and hard drives...

ijack's right. Your system needs registered ECC memory, and you're holding unregistered non-error correcting DIMMs. Expect to pay roughly twice as much for registered ECC vs unregistered.
