10/9 last one sold. locking this thread for now until I clean this thread up and put the next round of stuff to sell up


Hello everyone! I have one system left for sale. I went ahead and installed a BRAND NEW 120gb SSD and reinstalled Windows. The system is so much snappier and usable now. The SSD is from Microcenter (Inland) and the price reflected was my out of pocket price. I will include the cash receipt and box for warranty purposes.

$60 shipped.
Small SFF system, external power supply. Good workstation / web surfer system.
Dell Optiplex 755
Service Tag 7n7jrg1
CPU Intel E6550 Core2Duo 2.3ghz (dual core 2c/2t)
4GB DDR2 RAM
*BRAND NEW 120gb SSD*
CD-RW/DVD-ROM drive
Video output = DVI (cable included)
Clean & activated windows 10 1903 install

No keyboard or mice included.

Again, the price includes shipping. These things cost $20+ to ship so please factor that in.

Feel free to ask any questions!

I have the 755 and another system in the same generation as the 390 (990) and can vouch that these are really nice systems for just 'setting and forgetting'.

I upgraded my 755 to an e8500 which really woke up with the faster single-thread performance. An e8600 will also work (which I have pending to install):
https://www.cpubenchmark.net/compar...uo-E8500-vs-Intel-Core2-Duo-E8600/941vs5vs957

They even made a mount for the 755 for it to go behind a monitor. The CD/DVD drive on these is a shared platform with the Dell D-series Latitude laptops and you can add a second hard drive using a factory option. There is room in the case for a full 3.5" drive, but only a single sata connector and power, so can't put in dual ssds even though there is room. I think this is all I remember off the top of my head right now.

The 390 is definitely a much stronger system overall. It can be upgraded to an i7-2600 (one for sale here: https://hardforum.com/threads/fs-i7-2600.1985698/) as well as 16gb of ram, and you can also add a 1050Ti. The system can also use the i7-3770 (and others in that cpu generation) with the latest bios. Here's the very active threads where I pulled this information from:

Free bump for the op!

Hey SamirD thanks for the expansion options. You sure do know your Dells! :)

Wow I had no idea it was so expandable. I was thinking some more ram, SSD, and some kind of LP card like a 1050ti would be good enough for 1080 gaming. A $60 i7 upgrade option is cool.

Now I'm wondering if I should pimp these out a little and see if that gains more interest. CPU, RAM, SSD all easy and cheap enough. Inexpensive 1080p class LP cards are a little different story..

I think the 755 is a lost cause for gaming but a little ram and SSD upgrade and it's still an ok office type workstation.

I had to learn since that's all I could get my hands on for quite a while, lol. Plus, they are dirt cheap if you find them at the right price. My 990 was $55 with an i5, 8gb, 250gb + monitor and keyboard on CL in chicagoland.

If you can get the upgrades for free (or super-duper dirt cheap), then it would be worth putting them on to build the value of what you're selling. But with the current prices on Ryzens it's hard to sell systems like this anymore and the prices are tumbling on them. 390s with an i5 in them are basically at the $50 mark and will only fall further as the upgrade cycle continues. And it's not because these aren't capable systems, but rather you can get 'more bang for your buck' with some of the newer stuff.

The 755 is pretty basic, but is lightning fast with a lightweight 32-bit os like xp and a e8600 (max it can take). I'm sure even win7 32-bit will be pretty decent, but just for casual use as a desktop. The 755 is much better suited to just being a single 14tb freenas or some other such task that requires a decent cpu, gigabit ethernet, and some ram. Mine actually came loaded with Kodi. It will also probably run some versions of linux well. Basically a nice little tinkerbox.

Optiplex 755s will take Quads, just make sure you have the latest BIOS revision. Older BIOS revs could only use a Q6600/Q6700, but the A20 revision allows you to use up to a Q9650 with the appropriate copper core heatsink.

I've installed Q9650 and Q9550s with 8 GB of RAM in client machines and they really go fast.

Excellent. I have for sale just for you! :)

Well, this would work except what you have for sale is a USFF machine, which unfortunately due to its power supply, is only limited to dual cores--hence the e8600 will be the fastest that machine can take.

What's surprising is that the e8600 is actually faster on single thread performance than the q9650, so it will actually feel faster when it isn't bogged down too many threads:
https://www.cpubenchmark.net/compare/Intel-Core2-Quad-Q9650-vs-Intel-Core2-Duo-E8600/1050vs957

(For those that are interested, in the 745 USFF (previous version), you could put a quad core, but was limited to a fsb of 1066mhz, so I believe the q6700 was the fastest it could take. I have a q6600 in my 745, but it almost baked the caps because of insufficient cooling, so you have to watch that first as the caps were prone to overheating in the 745.)

For what it's worth, a q9650 is actually on par with a first gen i3 and even a low-powered lga2011 e5:
https://www.cpubenchmark.net/compar...i3-540-vs-Intel-Xeon-E5-2630L/1050vs738vs2222

It's an interesting piece of hardware that holds its own even today in certain applications. (y)
 
Tues bump and dropped prices. I am open to reasonable offers! Need to get these boxes outta here.

I run a q6600 in mine for the cores... No issues so far. Pretty good little systems, so bump to the top.

In a USFF? Mine won't even post due to being a 95w processor. The q6600 will work in a 745 USFF as I did that in mine and it works fine.
