Solved pc won't boot after installing new ram

Gateway Sx2800
September 6, 2013 at 16:35:14
Specs: Windows Vista, 2.336 GHz / 4094 MB
used crucial scan to determine what modules to buy (DDR3 PC3-10600, DDR3 (non-ECC)). bought an 8gb dual channel Team Elite set. (x2)4gb ddr3 1333 cl9 1.5v. after installing them and hitting the power button the fans and drives start, but no splash screen, and the beep is continuous instead of the quick single beep. bad modules or did i not match them up right? thanks!

You apparently didn't pay close attention to what Gateway & Crucial both listed. Your motherboard has 4 memory slots & accepts a max of 8GB RAM. Simple math should tell you the max per slot is 2GB. If you bought 2 x 4GB, there's the problem, you should have gotten 4 x 2GB. BTW, are you running the 64-bit version of Vista? If not, it's pointless to run more than 4GB RAM.

EDIT: another thing, if you have a 1066MHz FSB CPU, you should be running DDR3-1066. DDR3-1333 will work, but you'll take a slight performance hit because the CPU & RAM will be running out of sync. If you had a non-OEM system, all you'd have to do is increase the CPU FSB to 1333MHz to match the RAM & you'd end up with a significant performance gain. Unfortunately, it can't be done with a Gateway.

did you buy the ram 'used' on e-bay?
Does the PC still boot using the original ram?

First, did you purchase them from Crucial or a reputable source?
Second, are you running them by themselves or with what you had?
Third, did you purchase a matched pair, or two singles?
Fourth, did you make sure that the timings are the same as each other and what you have if running more than the two?
Fifth, try switching the positions of the memory.
Sixth, Try one stick at a time to verify any compatibility and to see if one is completely bad or mismatched.
Seventh, If you get anything with any of the memory, run Memtest via a bootable CD on each one.
And: (not really last, but just thought of it), If they recommend 8GB (2x4) set, what is your total maximum memory? If your maximum total is 8GB and you are adding the 8GB to what you had rather than replacing them, that might be the problem also.
Post your system specs.
If you purchased from Crucial, you also have their customer support to help you (possibly also if you purchased from one of their dealers as well).

You have to be a little bit crazy to keep you from going insane.

1)not used, brand new straight from newegg.
2)i was going to just run the new ram, not add to the old.
3/5)matched pair, tried switching with same results, tried moving them aswell.
4)not sure what timing is, but i tried to match as best i could see (pc-10600 1333 240pin ddr3 cl9 1.5v)
8)just trying to use 8gb, nothing more.

still working with original sticks.

I will try one stick at a time tomorrow as it is late now. thank you for your help.

thanks for the help riider. didn't realize i was limited to 2gb per slot, or even 8gb max. and yes, i am running 64bit vista. i also didn't realize i needed 1066 since crucial listed 1333 as their recommendation. slowly turning this into a non-oem system, but it takes time and some growing pains (not too computer savvy if you haven't noticed, lol).

if i were to buy two more 2gb sticks of ddr3-1066 and add them to what i currently have would i have any trouble since the four wouldn't be matched (two of A, and two of B)?

thanks again!

"slowly turning this into a non-oem system"

As long as it has a Gateway motherboard, it's an OEM system. The crippled Gateway BIOS is what prevents you from tweaking the settings & getting the most performance out of the system.

"if i were to buy two more 2gb sticks of ddr3-1066 and add them to what i currently have would i have any trouble since the four wouldn't be matched"

Match them up as closely as possible. Same speed, same voltage, same latency (CL). And make sure they're paired up correctly for dual channel mode, in other words, old w/old + new w/new, not old w/new + old w/new.

mobo and processor are the next upgrades. not looking for a monster, but a decent casual gaming rig. i hate seeing 'gateway sx2800' when i did the pc specs thing, lol. but for 400 bucks it was hard to beat at the time. thanks again for all your help!

so looking at the gateway support page, under processors it lists the core 2 quad as using up to 1333 mhz fsb. does that mean that i can use the 1333 ram? in that case i probably just tried using too much right? just want to make sure i get it right this time.

Gateway says FSB 1333 and RAM 1066:
http://support.gateway.com/s/deskto...
The 1333 memory should work in 2GB sticks, especially since crucial says it should, but it is possible that the BIOS would set it to 1066 anyway (though you can see if it lets you manually set it).
Crucial only shows 2x2Gb kits which you missed (as riider already pointed out) and Gateway shows 8GB maximum.
