Retrorockit A guy in India asked about cooling for 100*F. ambient temperature. I decided to drag out some of my old BTX Dimension E520 QX6800 overclocking parts. The X5470 = a 10% overclock on the popular Q9650 CPU. I used Throttlestop 6.00 to undervolt the Xeon to 1.1125V. Prime 95 Small FFT stable. I had already installed a lapped D9729 Pentium D cooler I had sitting around. I didn't lap the Xeon because of the no overclocking situation in the Opti 380. I pulled out the .9A. Foxconn fan and housing, and dropped in a Delta AFC1512DG 150x50mm 1.8A. fan. The bare fan replces the Optiplex fan and housing. Velcro and a little duct tape will give a soft mount and seal it up. Small FFTs and fan @2500 RPM the hottest core was 52*C. the 2 coldest were 47*C. I had to lift the heatsink to remove the old fan. I didn't reapply the TIM so there's probably air between the cpu and heatsink in places. Too bad he didn't ask before the Xeon swap. I could have undervolted the Q9505S 65W CPU and really cooled it down. Running the big fan @ 1100RPM and using the lightweight Throttlestop benchmark with 100% all cores I get the same temperatures as small FT @ 2500 RPM. The MB fan header had no problem doing a 1hour Small FFT burn in at full speed on the 1.8A. fan.

Retrorockit I put an X5470 in my Optiplex 380,8GB DDR3 1066, SSD, and GTX1060 3GB.

You can see the progression. Mine is the 1st,4th, and 7th ones on the list.
Most Optis won't run over a 95W CPU, or allow a Xeon swap. The Opti 380 does both.

If you're running a USB mouse or keyboard you might try some old PS2 stuff. It's more hardwired so the commands don't sit in queue as much. The whole weakness of Netburst was it's single thread nature. Causing everything to wait in line for something else to run. It also could be that the MB capacitors are getting ready to give up the ghost. I would inspect them for swelling or discoloration in the grooves on top.

Retrorockit The fastest Pentium D/4 will only equal the slowest Core2 CPUs. Keep the BTX cooler though. It's needed for the Quads. I don't see the 620 running anything newer than the Netburst CPUs. The 745, and E520 got upgraded, but not that one.

frostbite I’m running the D915 in the usff gx620 and am experiencing stutters and hangs in xp, especially when opening and closing apps.

This machine will only ever run old single threaded programs

Would sticking a p4 ht cure it or going back to D820?
It has the copper heatpipe cooler and mx4 paste.
I can’t remember if intel had an update for xp to run dual cores like amd had for the athlon64’s

I'm so sorry for the mental challenges that you face.
