These things really are BEASTS! I bought one for $99 off of eBay, added 4GB of RAM, Nvidia Geforce GT 610, and a TP-Link wireless card, and made it a Hackintosh. Runs amazing even though it's only a dual core. I need a bigger power supply...
I ordered this thing thinking it was gonna be crap. Our school uses a bunch of these and they are very slow. I'm surprised by the speed for an old computer. I think this will be the last actual computer i buy. Over time I will upgrade the stuff in it. Just ordered a new GPU. Good buy!
Just wondering if you got the final ram added for the total of 8gb? And if you did what mghz is it? Im wanting to top out my 745 mini tower, but i keep reading that I cant upgrade to 8gb at 800mghz. Just wondering if you encountered that problem if your sticks are 800mghz?
i can install 16GB (4x4gb) or 12gb (2x4gb + 2x2gb) or 8gb (4x2gb)??? i have 8gb (4x2gb only single) i wanna install dual channel my computer specs CPU: core 2 dou e7400 RAM: 8GB GPU: GTX 650 OS: Windows 7 please reply me
I currently am running 6 gb of ram but was wondering if I can upgrade to 14gb ‘s I’m wondering if my 755 is capable of doing 14g ? I have one 4gb plus 2 ( 1gb sticks ) installed.
windows consume ram memory, if you have windows 7 , they consume 750mb ram more/less , so that's why system shows you 3,25 ram available .also if you have 32bit version of windows, then system detect 3 - 3,5gb ram.. sooo ..it has to be like that, everything is fine :)
I have the same PC. I wanted to know if it is possible to install 16GB of RAM. I've seen people have managed to do it with G-Skill 4X4GB PC2-6400 of RAM. but the manufacturer says that it only supports 8GB maximum. I want to know if anyone has tried to put the 16GB of RAM in this PC and if they have not had any problems.
I do not know much about computers so please forgive the stupid question. If I put in extra memory, do I have to reinstall windows software or am I just adding more memory and not replacing memory.
Lol windows software is located on the HDD, not on the RAM. It will add more RAM so the computer will take less time to open applications and those sort of things.
Hello, I have an Optiplex 755 (same model as yours) and it came with 4 gb or RAM. I want to buy 2 more GB of RAM so i can run COD: Ghosts. What type of Ram should i buy? (like what DDR, and what brand and all that.) Thanks! :)
hey have a dell optiplex 755 i recently added a 2gb to the original 2gb i had, everything went good but after 2 days my pc started to slow down and when playing videogames the fps drops here is my pc specs: core 2 duo 2.83hz 4Gb of ram gpu : nvidia geforce 8600 gt 512mb
most schools here are too cheap to get these. we just have shitty windows XP custom builds. decent processors, terrible graphics and ram stats. these computers are freaking cool though.
got a 755 referb wanted to know about the BIOS "performance area" and if I should mess with the hard disk speed/noise settings. mine is running slow, and the factory is "bypass" for "older drives" but how old is old? 2006?
+Marcus Quiles 8Gb is Supported(Tested by Dell) 16Gb Works but is not tested by Dell Reason why dell did not test this machine with 16Gb is because there where no 4Gb sticks of ram at the time the pc was released
This is mis-information. The limitation is in the hardware. Even winx64 will just see the 3.25 What if somebody takes the time to switch OS (time consuming) to solve problem (based on your info) and finds out the TRUTH which is this is all you are going to see on this system. Due to chipset limitation. en.community.dell.com/support-forums/desktop/f/3514/t/18691359 BTW Why would Windows use 700MB of memory only on this machine? Doesn't do it on other machines. How is that a limitation in the software? My vostro 220 running same version of windows sees all 4GB? You should be more careful before you post so you don't waste peoples time.
Katie Serano I was talking about Vostro 200 3.2GB limit I have an optiplex 755 with 8GB RAM Intel Core 2 Quad 3GHZ Q9650 and low pro Radeon 5450 all in SFF. Its a beast! I use it as a headless slave video processor machine I did turn my CPU fan around it is a hot little machine and I will replace it in next 6mo for heat reasons (my room is too hot).
