390, CPU upgrades?

Am I able to install an i5-2500 into my Optiplex 390?  It currently has an i3-2120 and I'm just looking for budget upgrade options to increase performance in gaming. It's currently paired with a AMD Radeon HD 6870 which I plan on upgrading to Nvidia GTX 1050 Ti. 

Thanks!

Turbo Boost is specifically power limited by INTEL.  Its marketing.

You NEVER get full speed when all the cores are running.

When turbo boost is running it ONLY boosts 1 core.

Intel® Turbo Boost  depends upon a number of factors including, but not limited to, the following:

Type of workload
Number of active cores
Estimated current consumption
Estimated power consumption
Processor temperature

Intel® Turbo Boost allows the processor to operate ONE CORE at a power level for short durations

(A few seconds OR LESS)

Has nothing to do with new features. The SOCKET keeps changing because INTEL wants to sell more and more memory and cpus and chipsets.

The 390 is a crippled system with ATA only.  AHCI is not an option. There is a 2018 issued bios patch for Spectre / Meltdown.

The 2011 Optiplex 390 was only validated with the following i3/i5 CPUs =

CPU socket type: LGA 1155

MHF7R i5-2400 Sandy Bridge, 3.10GHz, 6MB, 95w, 4C, D2
950R3 i3-2130 Sandy Bridge, 3.40GHz, 3MB, 65w, 2C, Q0
972H5 i3-2120 Sandy Bridge, 3.30GHz, 3MB, 65w, Q0
5MH9T i3-2100 Sandy Bridge, 3.10GHz, 3MB, 65w Q0

Dell does not support any cpu other than the one that came with the system.

The 390 has an Intel H61 Express chipset which is different from the 790 and 990.

Whether or not the I7's work is up for debate.

If you DO NOT HAVE A TOWER any unit other than the "S" models will likely break the voltage regulator on the motherboard.  The smaller units do not have sufficient power.

So the i5-3340S - CM8063701387400 / BX80637I53340S  might work as would the

i7-2600 - CM8062300834302 / CM8062300834303 / BX80623I72600 / BXC80623I72600
i7-2600K - CM8062300833906 / CM8062300833908 / BX80623I72600K / BXC80623I72600K
i7-3770 - CM8063701211600 / BX80637I73770 / BXC80637I73770
i7-3770K - CM8063701211700 / CM8063701211701 / BX80637I73770K / BXC80637I73770K
i7-3770S - CM8063701211900 / CM8063701211901 / BX80637I73770S

This must be done via XP or 7 WITH NO ANTIVIRUS SOFTWARE INSTALLED.

Disabling does not work it must be removed and the system rebooted.  Then RUN BIOS UPDATE as Administrator.

Failing to heed this warning can lead to Bricked motherboard.

You cannot jump from A00 to A14 in bios so which depends on how old it is.

16 gigs is not an option if you only have 2 Ram Slots.

The 990 has 4 ram slots and allows 16 gigs.

https://www.crucial.com/usa/en/compatible-upgrade-for/Dell/optiplex-990-desktop

SFF is 8 Gigs Max end of storySFF is 8 Gigs Max end of story

8 Gig Dimms are NEVER an option.

Saying you can get to 16 gigs without restriction is misleading at best and a pre meditated lie at worst.

The ram must be LOW Density INTEL compatible and not be ECC or Registered or Buffered or Quad Rank etc.

It should be fine with the i5-2500. The 390 has an Intel H61 Express chipset which indicates that it should be compatible:

http://www.cpu-upgrade.com/mb-Intel_(chipsets)/H61_Express.html

However, Dell only ever shipped the 390 with CPU models up to the i5-2400 so it was never validated and can't be 100% guaranteed to work. If you are going to upgrade, I would advise updating the system BIOS beforehand.

No, it's a completely different socket type.  The 390 isn't one of the Dell's that can take a Ryzen.

I'm a big fan of Dell, a Dell user, and not an employee. This forum is user to user with occasional assistance by other Rockstars or Dell employees.

Hey All!

I have an Optiplex 390 with an i5-2400 cpu, 16 Gigs of memory and SSD drives. I installed an i7-2600k cpu today. When I go to power on the computer, the power comes on, then quickly shuts off. When I put the i5 cpu back in, the computer boots up.

Is there something that I am missing here? I have read that folks who upgraded to the i7-2600 had no issues with their computer booting up.

Fwiw...  I purchased the i7 from a trusted and reliable company. It was a refurb with a warranty.

Any help/guidance would greatly be appreciated!

Thanks in advance!

 

yes, chaz

got newest BIOS, A14? do not change CPU unless newest version BIOS is there.

the CPU you bought is bad.  happens. and is used 99% are now, gen 2 CPU are not new there are used.

youbought a K, version,  maybe dells newest bios does not support K.

K is not the only CPU that fits, here. ok>?

the Sandy Bridge CPU is here. (95watts or less)

the K version is the clock unlocked version that DELL does not support. seems like you BIOS don't like it.

tell me when changing processors, did you make sure all power is at  0vdc, (line cored pulled for 1hr)

AND REMOVE THE COIN CELL

change the processor, and next put in a new COIN cell if yours is below 2.9v (yea first things first on that)

then do the BIOS F2 reset to defaults and turn off PXE

did you do that ? these steps safe you from hotswap damage and forces the system to start  from scratch with new CPU, scanned. fully

the H61 chipset supports, 2600k but DELL DOES NOT SUPPORT THE FULL LIST for H61 (huge)

here is what 11,000 others did this is best place to look first,  but with A14 BIOS. yah.

nobody

i7-2600k  would use more power than the stock power supply/motherboard supports.

Yes, I did those things. Even put in a brand new lithium cell battery even though the one in there was good. The 2600K would still not allow the computer to power up.

Also... My power supply is a 500W unit, so enough to handle a 2600K cpu.

I was wondering if anyone on the forum is in fact actually running an i7-2600K on their Optiplex 390 mobo? If so, how did you get it to work?

Also... I was also wondering if there is not enough power going to the LGA1155 socket to power the 2600K? Is there a way to send more power to the socket for that cpu? And, could that be the reason for the 2600K not allowing the computer to power up?

Fwiw... I can exchange the 2600K with a 2600 (1st gen) cpu, but wanted to see if there any way to get the 2600K to work with this specific mobo.

Any help would be greatly appreciated?

Many thanks to the community in advance!

 

Have you tried a different cpu? If you switch to an i7-2600 it should run just fine. 

 

@chazcor 

Can I install a Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz [4 core(s) x64] in my DELL 390?
