the new info is at the bottom, belo the *'s

origionally called: 4gb per stick ddr2 (17 hours as of post to make decision i think)

ok this is what i'm looking at,
http://www.ebay.com/itm/Samsung-8GB-2X-4GB-PC2-6400-DDR2-800Mhz-240pin-Dimm-desktop-Memory-For-AMD-CPU-/351528225302?hash=item51d8b70a16:g:h2sAAOSwc0FUqoGN&autorefresh=true
if its real, than its a nice upgrade without sacrificing performance, and i looked up whats compatible, if the picture is what they are selling, its compatible with my motherboard.

lets say it is fake and its not this.
would non compatible ram kill my whole computer?

my motherboard is https://www.asus.com/Motherboards/M4A785M/

i will put this here, i have no interest AT ALL in building a new system even though that would solve my ram issue, i am CONSTANTLY running out of 8gb of ram, and windows is throwing up errors now that "i have no ram stop doing this to me"

i want this to be a stop gap till later this year when i can pour a few thousand into a new computer, i have no interest in building a new piece of crap that isn't better than what i have just for ram, i have been suggested "just get a pentium/i3/i5" other places and they refuse to have a conversation about more ram.

i do not want to pay for new windows on something i will use for less than a year, i dont want to reinstall every program, i do not want that hassle. i know its well meaning, but i do not want to do that.

***************************************************************************************************************
Ok at least one stick of the ram is bad, im doing the checks now, im hoping that the ram was seated wrong and thats what messed up, im going through it with memtest now stick by stick...

now, my old ram was g skill with the same speed, if one stick is bad i would like to still run with at least 2 of the sticks, but im wondering, could i pair a 4gb and a 2gb stick together? just having them in single channel or at wosrt all the ram at single channel? even would be nice to have 14gb of ram instead of just 12

So long as the voltage is the same as what you've got in the system already (or you're going to take out your existing RAM) it shouldn't do any harm.

As for compatibility, I can't see any problems but you never know until you actually try it. (ASUS boards are usually pretty good-natured - I used a couple of sticks of this in my old P5KPL-VM Core 2 Duo system at work a couple of years ago - it only had 2 slots and 4GB wasn't enough when I was running a couple of VMs with different versions of Windows.)

motherboard is 6 years old, it not exactly new



going to replace it all, 30$ for 16gb total is a bargain as far as i am concerned, and will comfortably hold me over till what i have the money for the full system build.

if you read under the *'s this is just a paste of that.

new development, each piece of ram works individually, each slot works, i put 2 piece in and it works, but if i put in 3 it wont show anything, if i put in all 4, it shows stuff but brings back a crap load of errors

any thoughts?

going to tell you now i have no idea how to do that, i spent about 3 hours doing the diagnostics to see if any of the ram was not working, than at least another hour dicking around in the bios to see what i could possibly change to make it work.

i kind of steered away from anything i have no idea what it was or if it could possibly kill off the ram/system if i set it wrong. i don't know if there is a bios overview somewhere where you could point to the setting i want to mess with, if there is i would be greatfull.

i want to get in contact with asus about this, but i have no way of doing that without the serial number, and that is possibly on the back of the motherboard... my gpu was hard enough to fit into my case the first time, and i really don't want to take the motherboard out just for that... hell i have a decent cpu cooler i could use but i don't have back panel access so i don't use it, i would look at the box, if i had it, the mother board and cpu were sold to me by a repair shop around 6 years ago when i had no means to buy or diagnose a computer problem (still don't for the type of problem i had) so really any help you can give is much appreciated.

new bit of info, i'm asking largely the same question on steam forums at the same time, the guy said he had to increase his memory voltage by .15 to get it to work but said he had the exact same problem i'm describing.

i'm assuming thats if he wants to keep the same speed, before i want to mess with voltage i would be willing to lose speed, hell, i looked into downclocking a year or so ago so i didn't have to worry about overheating my cpu when i thought my computer was shutting down due to heat.

just trying to understand all my options.

currently, 4 sticks of 2gb g skill that is the same speed as the ram im going to replace it with, or at least want to.
phenom 955 be with stock cooler
motherboard is in the original post.
280X factory oc to a ghz edition speed.
1 bluray drive,
1 ide133 (i think thats what its called) dvd drive, i would take it out but have had horrible experiences in the past dealing with that cable in a different build, so im leaving well enough alone
i think a 12 year old 250gb drive
a 1.5tb drive
a 4tb drive
and a second 4tb drive
with a 120gb intel ssd boot.
i think there is also a 6 connection usb2 pci card, it could be usb1, not to sure but its another leaving well enough alone.

with a 700watt corsair (sp) psu

i think that is everything.

And the ram is in and running a memtest showed no errors after a full pass. god it feels good to have enough ram, so much crap use to move to the page file constantly, even though the ram is slower i fully expect to have a much more pleasant experience using the computer. not to mention how much of a nightmare it was trying to get my ram use under 5gb so i could launch games without hitting the 100% mark...

thankyou.
