whats going on with core 2 quad and windows?

DirtyBiker · 2024-11-17T15:57:18+0000

I've recently reacquired an old Dell OptiPlex 380 SFF that I custom-built years ago for my nephew to play Fortnite. After a clean installation of Windows 10, I encountered issues with launching several applications that previously worked fine, such as Cinebench R15, MSI Kombustor, ASUS ROG Furmark, and Fortnite. Despite trying older versions of Kombustor, the problem persists. The machine generally performs well, as it's equipped with a new-old-stock Dell OptiPlex 380 motherboard, a 775 to 771 BIOS mod, and a Xeon E5450 processor, along with a custom vertical-mounted GTX 1050 TI. I suspect the issue may be related to the absence of SSE4.2 instructions, although these applications functioned correctly before. I would appreciate any thoughts or insights on getting this machine operational.

Was it running windows 10 before? If so, I doubt that is the issue.

Maybe a stupid question but does task manager show all 4 cores?

Only Win 11 24H2 is bootable only on SSE 4.2 CPUs so far. 10 should not be affected as far as I know.

Unplug the gpu, and see if you get the same result with the onboard video. that will narrow it down a bit.

BTW, love the avatar. That episode of Beavis and Butthead where Cornholio does open mic poetry is fantastic.

If you see SSE4.1 support in CPU-z you are good on that end.
I'm more worried about your RAM being "iffy" and just developed a fault, check with memtest86+.
Another option is caps on MB or PSU being marginal (this is 15 year old hardware after all).
Q : Did you enabled .NET 3.x support from Windows features ?

….Despite trying older versions of Kombustor, the problem persists.

What kind of issues are those? They don’t start?
Some kind of error message?

Why not more specific about it?

Honestly, I'm surprised you were able to get Win10 installed.

The Xeon E5450 does not support the CMPXCHG16B instruction, which 64-bit Win10 currently requires. The E5450 is based on Penryn (Core 2) architecture, a direct predecessor to Nehelem (Core Gen1). And Nehelem was the first architecture which included CMPXCHG16B Intel-side.

EDIT:
With more digging, it appears that later revisions of Penryn-based CPUs supported CMPXCHG16B, but some motherboards did not enable it.

I don't understand people who ask for help while supplying none of the information actually required to help them. I'm convinced it's a mental illness.

The capacitors all look good. It was a NOS 380 motherboard when I built it. I installed it in an OptiPlex 755 case with the 755's 280W PSU. Are you referring to .NET Framework 3.5? It was disabled, but I just enabled it and there was no change. I ran Dell's built-in hardware test and no issues were found. I will try swapping in different RAM sticks one at a time, but in AIDA64, the performance benchmarks are on par with the QX9650.

installed windows 11 23H2 via rufus as well as windows 10 using media creation tool it all worked excellent for years as my nephew played Fortnite with this machine all be it in performance mode locked @

What, exactly, are the issues you encountered? You're a bit vague on this. Are they performing worse? Are they not starting at all? Error messages? If they worked fine before and a fresh Windows installation is what changed that, then I wonder if maybe there's some dependency software they need that isn't present? So maybe you just need to reinstall something.

Otherwise, maybe age is catching up to it. I have an OptiPlex 380 and it's definitely an older and very, very slow PC these days. Have you considered that maybe your time apart from it, on what I presume it's newer and faster hardware, has led you to misjudge its performance? I find that sometimes that explains this because we get accustomed to faster hardware and overestimate how slow the slower hardware now is, and software also gets more demanding in the meantime too (for example, isn't Fortnite an Unreal Engine game that has been seeing game/engine updates and becoming much more demanding over the years?).

It could also be something aging and breaking down as others have mentioned? My OptiPlex 380 is the desktop form factor (the larger variant of the SFF you have), but I dealt with that SFF size with another OptiPlex of a different model though (same Core 2 era), and that thing seemed to warm up the outer case to a concerning degree above the PSU just running League of Legends or Minecraft. I also noticed that when I swapped the E8600 out for the Q9550, that sometimes the intake fan would ramp up to maximum speed even when the CPU temperature was low. My guess was that despite the PC supporting those higher wattage quad cores, the VRMs may get hot doing so at times? I can only imagine this being worse on a much smaller form factor. Basically, with a quad core CPU and a more of a GPU than that PC was probably ever meant to handle, maybe a combination of age and wear and tear, plus increasing software demands, has caught up with something?

I've recently reacquired an old Dell OptiPlex 380 SFF that I custom-built years ago for my nephew to play Fortnite. After a clean installation of Windows 10, I encountered issues with launching several applications that previously worked fine, such as Cinebench R15, MSI Kombustor, ASUS ROG Furmark, and Fortnite. Despite trying older versions of Kombustor, the problem persists. The machine generally performs well, as it's equipped with a new-old-stock Dell OptiPlex 380 motherboard, a 775 to 771 BIOS mod, and a Xeon E5450 processor, along with a custom vertical-mounted GTX 1050 TI. I suspect the issue may be related to the absence of SSE4.2 instructions, although these applications functioned correctly before. I would appreciate any thoughts or insights on getting this machine operational.

Isn't there also a pin mod that needs to accompany the bios mod? I vaguely remember something about covering a couple pins or something.....

First off, Win 10 wasn't really meant for a machine of that vintage because it's for newer, more modern machines.
Win 10 itself might run "OK" with it but as you've mentioned yourself, there are things about Win 10 that makes this particular OS/hardware combo not a smart thing to do.

OS requirements for Win 10 just to run "Correctly" are different/greater than an OS from the time when the machine was built.
The amount of RAM required is one example:
What is the recommended system requirement for windows 10? - Microsoft Community

Note the overall recommended requirements are simple, basic requirements for it to run correctly period, meaning for basic functionality and nothing more... Like a simple office machine.
Compare these to what you have in the machine and go from there.

Referring to RAM:
If your machine can't either run or support more than 4GB's you already have a potential problem in play.

Instruction sets are another thing and I seriously doubt your machine can run some of these, either correctly or at all.
Just because things like Cinebench R15, MSI Kombustor, ASUS ROG Furmark, and Fortnite all ran fine before on an older OS version/copy, there is no guarantee they would with a newer OS version/copy.

Although Win 10 CAN run on older hardware (Yes - I've done it myself) it also shows the limitations of such hardware too.

You also haven't said what OS version of Windows it was running fine on before, which if was an older one like Win 7 that's just natural and it's even expected, given what you have.

So.....
How about more details about what was done before with it so we can understand better/more of what you are really getting at here?
That would help.

What kind of issues are those? They don’t start?
Some kind of error message?

Why not more specific about it?

I've posted the Cinebench crash report. There was no message when launching Kombustor or Furmark ROG, but Fortnite displayed an SSE4.2 error.

What, exactly, are the issues you encountered? You're a bit vague on this. Are they performing worse? Are they not starting at all? Error messages? If they worked fine before and a fresh Windows installation is what changed that, then I wonder if maybe there's some dependency software they need that isn't present? So maybe you just need to reinstall something.

Otherwise, maybe age is catching up to it. I have an OptiPlex 380 and it's definitely an older and very, very slow PC these days.

I posted the Cinebench R15 crash report in replies the E5450 is a lower wattage version of the C2Q CPU's the power supply tested fine no heating issues as I set it up with an additional cooling fan at the rear as well as reversed the air flow to exhaust out the front temps have always been verry good at or under 60c under load on the cores GPU idling in the low 30's as I have not been able to stress test it due to these applications failing to load even the SSD temp is in the 30's and its mounted under the DVD drive

Was it running windows 10 before? If so, I doubt that is the issue.

Yes, it had Windows 10, but he hadn't used the computer for over two years while he was in college. He only recently got internet in his new apartment but hadn't set it up yet. I repurposed the SSD for the new computer I built for him, but I didn't test it beforehand; instead, I performed a clean installation of Windows on a different SSD on the OptiPlex.

Maybe a stupid question but does task manager show all 4 cores?

Yes, all four are operating at 3.0 GHz.

I've posted the Cinebench crash report in the comments. Fortnite displays the SSE4.2 error, and other applications fail to launch. However, I managed to load Kombuster before installing the GPU driver, but when I ran the test, it simply exited the program.

Honestly, I'm surprised you were able to get Win10 installed.

The Xeon E5450 does not support the CMPXCHG16B instruction, which 64-bit Win10 currently requires. The E5450 is based on Penryn (Core 2) architecture, a direct predecessor to Nehelem (Core Gen1). And Nehelem was the first architecture which included CMPXCHG16B Intel-side.

All Core2 CPUs should support CMPXCHG16B, even some later Pentium 4's have it. That was mainly a problem on AMD S939 and earlier Pentium 4's.

Here's my C2Q Q9550 for proof. I don't have any of the problems OP has with programs not working, or at least ones that don't need SSE4.2, AVX, AVX2 etc.

If you see SSE4.1 support in CPU-z you are good on that end.
I'm more worried about your RAM being "iffy" and just developed a fault, check with memtest86+.
Another option is caps on MB or PSU being marginal (this is 15 year old hardware after all).
Q : Did you enabled .NET 3.x support from Windows features ?

Yes, SSE4.1 is present. The RAM tested fine using Dell's built-in hardware tester, and the capacitors all look like new. I even opened the PSU to clean and inspect it before powering it on, as it had been sitting for over two years. All voltages and temperatures are within the normal range according to AIDA64. Are you referring to .NET Framework 3.5? It was disabled by default, but I enabled it and installed it successfully; however, there was no change.
