Alright, I need help with my machine. I want to upgrade to the core 2 duo processor and want to be able to know if it would be supported with no problems. Before I make the purchase on a new processor, I would like to know if any body tried upgrading this machine to core 2 duo. I checked around Intel's site, and it has information that the chipset will support core 2 duo.

- Dell Optiplex Gx620 Memory Specs
- Dell Optiplex Gx620 Specifications Desktop
But I don't know if it is actually supported by the machine. Hence, I looked around google and found no articles on it. I want at least an Intel core 2 duo 2.40Ghz. I also know I would need to upgrade my memory. Thanks, John.
No the board will support up to 1066Mhz FSB according to to intel's PDF guide on the chipset. Only one way to find out. Im going to install my Core 2 Duo 2.8 in my GX620 tower right now. I have the same one you have, so lets see. I wouldn't try this unless you want to 'fry' your Core 2 Duo. However, the GX620 DOES support the 9xx series of Pentium D processors. Just make sure you have the latest BIOS.
I currently have a Pentium D 940 processor (SL95W) running W7 Professional (64-bit) on my Optiplex GX620. And, it runs W7 Pro (64-bit) VERY respectfully, considering that the Pentium D is 'old' technology. My minimum W7 WEI score is 5.0 (the processor, of course). You can 'goose' performance a little by using the Pentium D 950 processor (I recommend the SL95V, for economy and cooler temperatures.). Anyway, if you go this route, you might want to consider a beefed-up power supply, and a supplementary fan(s) blowing on your W7 compatible video card.
Also, think about getting a supplementary case exhaust fan (at least 80mm) to help get rid of the heat. Even the recommended 95 watt versions of the Pentium D can run hot. Of course, if you're just going to run XP, or Linux, it probably won't pay to upgrade your processor. Hope this info helps. Dont know but for all those interested the intell board for the Dell 620 supports 1066fbs.Im running a pentium D second generation in mine right now.According to the specs though it should support Core 2 duo.The board has intel 945cg chipset and you must install the latest bios which is A11.its easy to install just download from Dell suport site save and run,its an exe file and it will do everything automaticaly.This bios update allows support for newer processor up to 1066fbs. I however recomend the better heatsink with the 4 copper heatpipes for more effcient cooling.Also add an additional fan for cooling.Im also using pc 800 dual channel corsair ram.The machine nisnt to shabby for multitasking.
HT=hyper threading,Pentium D has speedstep inhancement no hyper threading.That being said its still faster but they run hot as stated up 120.f.The 9 series D doesnt run quite as hot though. I've just 'upgraded my son's GX620 based on this thread. I went from a Pentium 4 630 SL8Q7 to a Pentium D 945. It worked first time but when I ran the W7 WEI the score for the CPU had actually gone down from 3.2 to 3.2!! Was this a smart move or havbe I taken a step backwards (at a cost of £40!!) cheers, Daran. Wow, old Dell's get new LEASE on LIFE, read about it here! I got one with bad caps, among several SX280s, so small there is no room for PCI cards of any type, the SFF GX620 is meant for HT single core Pentium Celeron, also specs list lower then 800 speed DDR2, which is what I just bought.
I got a 3.2Gig PentiumD that did not work on the SX280s, or an IBM M51 tower, it worked on a 3rd party MSI board for 45nm tech Quad and Core2Duo chips, so it's a 'fill in' on that board since I lack those fancy CPUs, they also sold out of the PentiumDs they did have for sale, bought the one and then they were gone! Anyway, I would like something GTA game capable, GTA4, which has problems with PCs due to what people call 'porting from console'??
Not sure what to believe there though. I have a dell optiplex gx620 full tower. I tryed running gta 4 on it and it didn't go well.!

Hi i tried the core 2 due with no luck i have the latest bios a11! So im going to try the Pentium D 900 series processor like a 925 or 950 will any one work as long as its socket 775? There are laods! I just obtained (recycled) a GX620 desktop and will be upgrading to a Pentium D 930 chip to support VT-x and will use it for VMWare ESXi. Have installed 4GB of memory, 1.5TB & 2TB internal 5400 RPM Sata drives.
Will report on how it goes. I will run several linux images on for samba (for multimedia sharing, backup space), apache, dokuwiki, dhcpd and several other services at home.
It will allow me to manage the services with one box, even when I upgrade or change Linux OS or make other major changes. I figure with a minimal investment ($150) in hardware the payback in electrical savings (going from 2 systems to 1) will be about 9 months. So far so good.
I've got ESXi 4.1.0 running. One tip, after installing the VT capable CPU and Upgrading the BIOS to A11, when trying to create a 64-bit VM, ESXi complained that the CPU was not VT enabled. So I powered off the machine. Unplugged the power supply from the motherboard, removed the BIOS battery, and set the reset jumper for 5 seconds. After I put everything back and powered on the machine, I was able to enter the BIOS and now under Performance there was a Virtualization option which I turned on.
Then everything worked. Another minor issue: I have 4GB of memory (4@1GB), however VMWare only reports 3,324.9mb of memory. This is not a problem for me as my VMs are not that resource intensive.
The Optiplex GX620 does support dual core processor but its the pentium d dual core,not the intel duo core which is newer version of the dual core processors.all i had to do was a bios flash and i'm flying with a 3.2 gig pentium d dual core processor. I have the GX620 also and would like to know if it will handle a 3.46 ghz Pentium D dual core. I have an opportunity to get this processor and also understand it will run 1066 mhz ddr2 memory in lieu of the 800 mhz. Does anyone know if this combo will work ( I know the bios must be updated). But does anyone see any other problems.thanks rocknroller.

I also have a GX620 mid-tower and want to upgrade. My idea is to change processors to a 950 (3.2 ghz or a 3.4 ghz.960 I think) and add 2 sticks x 2gb ddr2 ram giving (6400 or 800 mhz) dual channel, and of course, update the bios to handle the changes.
Anyone know if this combo will support 1066 mhz ram? I realize this is a bit of trouble but I am planning on using the unit strictly for media such as streaming video and such. Also want to add a pci express card to provide HDMI output including audio on the HDMI cable (also need advice on the best card for this). Would greatly appreciate any suggestions on these mods and whether or not I am better off to change out the MB and update from there, please advise.thanks.rocknroller. I have several GX620 SFF and am planning to use one as an HTPC.
Although I am not using it now. (Our company throws out old systems and I collect anything useful). I am currently running a Win 7 Ultimate HTPC (using USB TV tuner card for over the air DVR functionality) on a GX280 with a 3.4Ghz Pentium 4 (single core) and it works decently for 720p. I don't think you need ultra performance for this.
A decent processor, Pentium D only (dual core 3.2 and above) and 4GB of decent memory is probably enough. I don't think you need 1066 memory.
Even though the CPU may support the fast memory, I think the motherboard and supporting chips need to support it too. As for the video card, the SFF case I am planning to use needs a low profile card and low power utilization.
Dell Optiplex Gx620 Memory Specs
I was looking at the Sparkle GeForce 210 card from Newegg. It has VGA, DVI and HDMI. I also want to connect it to a Home Theater receiver and was looking at a Xonar DG 5.1 or 7.1 to provide optical digital sound output. Are you planning to have this streaming video machine anywhere where the sound might be a concern?
If you do, try to pick low power components so it isn't too noisy. Intel has some great web pages on it's various CPUs and power requirements. I picked a 930 processor for a GX620 desktop which had lower power utilization than some other similar chips.
If I remember correctly I have a 945 (3.4Ghz) sitting around for one of these machine. I haven't tried it yet, but if you want I can test if it works on the GX620. There are two differences between the 945 and 950. The 950 supports virtualization and uses more power.
Otherwise they are the same. Also I'd advise installing as little other software as possible. Less software to steal CPU cycles. Yesterday I started setting up my GX620 SFF for HTPC.
I upgraded the BIOS to A11. I installed the Intel 945 Pentium D (3.4Ghz), Zotac GeForce 210 card 1GB DDR3 (passively cooled - max 18watts) and the Xonar DG 5.1 (optical audio out - no HDMI on my old Home Theater receiver).
Dell Optiplex Gx620 Specifications Desktop
Used 4GB (2x2) DDR2 667 memory (which clocked down to 533?), so I doubt faster memory would have any benefit. Using a WD Caviar Blue 500GB hard drive and Window 7 Enterprise 64 bit. All is working fine. No problems yet with the power supply (only 275 watts). However it runs a bit warm.
I will do further research to determine if it's too hot and/or too noisy for HTPC use. If I need to, I'll consider installing the Hard drive outside the case to give more room for cooling the video card. Yesterday I started setting up my GX620 SFF for HTPC. I upgraded the BIOS to A11.

Did you replace the heat sink as well? If so, where did you get one? I'm trying to upgrade my gx620 to a dual core as well. Did you replace the heat sink as well? If so, where did you get one? I used the same heatsink that came with the SFF GX620. The system originally had a 2.8Ghz Pentium D.
Note: You can't put a Core 2 CPU in the gx620. Just the Pentium D's or Pentium 4s. If you want I can take a picture of the heatsink.
What CPU (Intel model number ie. 820, 945 etc.) do you want to put in it? Is it a Small Form Factor case? There are 4 different cases for the GX620 USFF, SFF, Desktop, Mini-Tower.
Each has a bit different cooling setup. See: Unfortunately I have not found software that could monitor the system temperature, but my setup seems to be working with no problems. The CPU barely breaks a sweat no matter what I am doing. I do monitor the video card temperature which is quite hot but has not caused any problems (at 1080p) yet (peaks in the mid 70s C).
It is clearly not a silent PC, but it's tolerable. We watch a lot of Netflix, Hulu, record and watch recorded TV using Windows Media Center (off a Silicon Dust HD Homerun dual) and various other content. I have a bunch of these and one had bad caps another worked fine. The other two not sure yet. Anyway there's one major major flaw and it's the heatsink design. There is too much gap between the core cpu and the heatsink.
I even added a 1mm thick thermal pad and contact was very poor. So we need to figure out the hole parameters and see what will mount in replacement. Another thing to try is a 2mm thick shim or even 3mm thick shim 2'x2' and crank it down tight. The contact is poor and pressure is even worse so a shim is required. Since the temps we see with the GX620 are very extreme.
There is no sensor because DELL didn't want customers literally shitting themselves when they saw the idle temperature. We know the pressure is poor because the instant it goes under load the fan skyrockets and we notice thermal throttling on all the Pentium 4's and Pentium D's. It's insta-throttling so the second you go under load your seeing 1-20% of it's true potential out of any CPU. In other words at high load we see as much performance as say a Athlon XP 1500+ or some such junk. I tested different CPU's and some have said Core 2 Duo's work and they just might. Will need further testing but I have a Core 2 duo 6300, p4 3.2, 3.4, 3.8, and Pentium Dual Core 1.8Ghz I believe.
A cpu success is a green light after boot up, an amber LED indicates cpu post failure and the chip stays cold. Tested Core 2 Duo 6300. Amber led cold cpu. Although the board I tested has bad caps.
I'll test on another and report back. I also suspect the Screw/ Thread/ heatsink dimensions may work with a LGA1366 heatsink. I'd also try and connect the northbridge to the CPU heatsink by use of a large piece of copper shim enough to cover the whole and run across to the northbridge.
This way the Extreme 'typical' heat from the northbridge can be dissipated by the cpu heatsink directly. From my experience the reference design of the GX620 is very poor in terms of cooling. The northbridge regularly seeing 85C+ at idle and load approaches and exceeds 100C+ under load. All the while EXTREME throttling is occuring because it's all running way way way too hot. So if we can compress the CPU and Northbridge under a Copper shim I'd say 3mm thick to be safe across the CPU, and Northbridge and crank down the heatsinks tight we should see very low 60C load temps on the CPU and Northbridge and load it out and get perfect performance.
Far better than DELL had ever imagined. I'm talking about a copper Sheet 3-5mm Thick just to be extra safe between 3 and 5mm so 4mm or so would work. The demensions would be 4'x4' but u may need to trim with TIN SNIPS, also test for flatness on a pane of glass with soap.

YES OLD THREAD BUT IT'S NICE JOINING A GX620 GRAVE YARD DISCUSSION. He said Dell Optiplex GX620 in title. No it will nto work, since yuour MB only supports up to a 8000MHz FSB. If you bought a Core2 Duo, you would need a board that does 1066 or 1333 FSB. OK but wait there are Core 2 chips that are 800 FSB and I'm looking at one now - Core 2 Duo 4300 SL9TB 1.80Ghz/2M/800/06 - isn't the 800 after the cache size the FSB speed?
Yes It's slower than the Pentium 4 HT 3.2Ghz that is in the unit now, so not sure if there are any real gains overall. But the question remains how to side load the correct BIOS to support a newer chip. From what I can see the CPU and BOARD have the ability, its just the BIOS that is holding an upgrade back. And the board can go faster than an 800 FSB but at the current 800 FSB wouldn't the 4300 CPU mentioned be an easy swap and may not need a newer BIOS flash?
Is there a guide to what DELL BIOS versions provide specific chip support? I have yet to find any tables that can easily be referenced. As anyone tried this, as I need to know asap. I have Old dell optiplex gx620 desktop.
I bought it old used from my local market. It lasted me fine till few month back. And now I since orange light came, I either need to change the motherboard, or buy a used other whole pc. I have p4 2.8 MHz n 3 gb ram n 2hdd 250gb each sata n dvdrw in it. Now here is the question, if anyone tried it. Has anyone removed the old motherboard and processor and replaced it with either dell optiplex 760 motherboard(Intel q35) n c2d 3.0 ghz with existing ddr 2 ram or even with dell optiplex 780 motherboard(Intel q45 or Intel q43) n c2d 3.0 ghz pro n 4-8 gb ddr 3 ram. If it can be done then that what I will do, otherwise buy a another used system of dell optiplex 760 or 780 or even Hp 7900 or hp8000.
Otherwise I increase my budget n buy used haswell g3220 or i3-4150 complete system. This will only be done if I can instead these board n processor in gx620 since with ram n hdd it will sell for $5 here only.
I have several GX620 and GX745, GX755 machines. On the GX620 it does not support the Core 2 chipset in BIOS. The best it can take is a Dual Core Pentium D 8XX processor. But the good news is that the DELL case and power supply are almost identical for these three models, so you can just replace the DELL GX620 motherboard with a new 700 series board and gain support for the Core 2 DUO and QUAD chipset. That's about the cheapest solution for you. The GX620's memory may work in you 700 board depending on which one you select. Some newer boards may require DDR3 memory so best to check the DELL website for the specifics.
The good thing is that DELL unlike HP posts the full service manuals online making the job a bit easier. I have several GX620 and GX745, GX755 machines. On the GX620 it does not support the Core 2 chipset in BIOS.
