OptiPlex 755 upgrade

Question

Hello, I'm planning to upgrade my OptiPlex 755.

My current specifications are as follows:

CPU - Intel Core2 Duo E6550 @ 2.33GHz

GPU - NVIDIA GT 240

RAM - 6GB DDR2

My upgrade will be:

CPU - AMD Athlon 3000G

GPU - NVIDIA GTX 970

Would this work with the OptiPlex 755? If not, what would be a suitable upgrade for these parts?

speedstep · Accepted Answer

The 755 does not support ANY AMD processor.

The 755 video slot is 1 slot wide. There are no dual slot 755 models.

So none of what you want to do works ever.

Power supply can be upgraded but the cards that fit do not need more than the 305W unit in the mini tower. Smaller cases cannot use a standard power supply and have no upgrades.

16 gig is not an option.

AHCI setting for SATA OPERATION supports standard SSD drives.

A 13 year old 755 would not have ANY warranty.

i am also looking to do an upgrade on my 755 and my specs are :

CPU - Intel Core2 Duo E6550 @ 2.33GHz

4 gb of ram and i don't have a GPU didn't even know you can install any in them .

I am thinking of upgrading the ram to like 8gb or 16gb and getting an ssd , but im having a hard time figuring out the CPU to get. I am just trying to get the best possible parts that can still run well on it currently .

So can I go up to 8gb ram instead and if so what ram would be a fit and for the cpu ,what’s the best I can get for the computer currently

For the SFF version, I upgraded to Intel Core2Quad 8400, 4GB+4GB=8GB Ram, AMD Radeon R250 (4GB) LP Graphics, TwinMOS 512GB SATA SSD. Runs good.
