Acer Veriton 275 Memory upgrade trouble

[RrufusTW]

Hello all, I'm hoping for a little help from anyone who might be able.
I am trying to install 4gb of Ballistix Sport pc3 10600,ddr3 -1333 in my Acer Veriton M275.
Everything I can find about it says it is compatible with my machine the Crucial website says it is using my machine's model number.
However when I install it I get the annoying long beep of memory sadness. Won't even post.
Link for service manual with pics of bios setup pages- http://www.manualslib.com/manual/232986/Acer-Veriton-M275.html

I have the default 250w psu.
E8600 cpu
Chipset is Intell G41
Windows7 64

Thanks in advance for any help.

What chips did it have before?

What chips did it have before?

The original ram that is still in there is Kingston, the cheap looking stuff.
I've got it up and running at the moment got dueling searching for help going on with my laptop. I'll shut it down and yank it out

What chips did it have before?

It's
Kingston ACR256X64D3U133C9

I think I just figured it out. The old stuff is registered.

You have Acer Veriton M275.
Here is the spec-sheet for kingston.

You purchased Ballistix Sport pc3 10600,ddr3 -1333

I do not understand why you want to replace the Kingston with Ballistix

[RrufusTW]

I wanted to up the memory to 4gigs, with only 2 gigs it gets slower with every update. Windows 7 64 uses almost 2 gigs alone.
I wanted to get matching memory so I bought the 2 Ballistix 2gig sticks.
I bought them going off my Mobos specs, I also looked up the memory on Crucial website using the model numbers of the memory and the computer and it said it would work.

Looking up the old ram specs says the ram in it is registered, this is the only difference I can find that could make it not work. So your asking me that question of what the old chips were may have giving me the answer I needed.
However all the places that want to sell me memory want me to buy the non ecc stuff.

Thanks for the replies BTW.

Well, I don't really understand. You should  be able to used either type.
Here is a video.

Watch it to the end and another clip comes on with more information. Then comes even more. But only some of the info would apply to you.
Anyway, you need to talk to Crucial and find out what went wrong.

Neither did I! 
According to all memory sellers including Crucial I should be able to use it...

Thanks for the video, but I'm not completely in the dark when it comes to computers, I have built,tinkered about with and upgraded 100s of machines over the years. I used to haul them home from the dump to tear them down and build all kinds of Frankensteins. 
From what I can tell tho it's not going to use Non ECC memory and must have registered memory.

Can you see in the BIOS if there is a way to disable ECC?

It uses non ECC memory so your assumption is off base...
Is the new RAM 1066 ? ?
And each slot only supports so much.

That being stated that'sn about the worst written User Manual i've seen in 5 years...

No there isn't, I've found a post on the Acer forum from a tech that says there only 7 chips that they guarantee will work and he only listed 3 of those in the response.
So found a listing on Ebay for an identical stick as the one in it and bought it.
I'll finally get the 4 gigs I was going for at least, just hate buying used memory.

The new RAM is the same specs as the Kingston RAM that is in it except for the Non ECC part.
From what all I've been able to find some workstation PCs will only use the Registered 72bit RAM.

And YES the Service Guide as well as the Owner's Manual are just about as vague and unhelpful as I've ever seen.

This is the first time I've been so baffled by a machine that I asked anyone for help.
I think I was hoping that some guy named "CAPTAIN ACER" would swoop in and use his Veriton super powers to save the day! 
I can do that with Ford automobiles, someone has some weird problem and I'm like "Oh yeah that's some weird crap only those models have and they don't tell you so you have to..."
Thanks guys.
I decided the solution was buy more stuff!! LOL
