Upgrade BIOSTAR H55 A+ v6.3 with Xeon X3440 2.5 @ 3.8 GHz
Hi.
I need help upgrading the OC settings for my CPU to 3.8 GHz on this BIOSTAR H55 A+ board. Here are some recommended videos:

Let me know if you need anything else.
90C is too high. You should either lower your voltage or increase overclocking, or enhance your cooling system. If the system crashes because of overheating, the only real solution is to cool it more effectively. I would try to avoid reaching 75C under load.
Every CPU is unique, there are no one-size-fits-all settings for guaranteed overclocking—it could be that your chip simply can't handle that speed.
To increase the performance of a Lynnfield CPU such as your X3440, you should modify the base clock (BCLK). Since the X3440 employs a 19x multiplier, and under certain conditions it can reach up to 20x/21x/22x when only some cores are active and temperatures remain low, setting the BCLK around 200MHz will be necessary to achieve 3.8GHz. This level of speed usually demands further adjustments to system voltages and memory timings for stability.

I achieve 3.8 GHz, but the system becomes unstable—games crash after short periods when temperatures approach 90°C. Any suggestions?
P.S.: My CPU cooler is a Uphere:

Just to note, I recently purchased x3440 and set up Easy Stable at 3.8GHz with 1.3V. It performed well without any issues, maintaining temperatures between 70-75°C during Cinebench tests. During gaming sessions, especially in games like PUGBDOTA2, it stayed around 60°C. I’m open to adjusting voltages, but I prefer stable performance. I’m also considering higher voltages, though I want to keep temperatures under control. My PC is in a gaming environment, and I’ve already reached 19x with 200GB RAM. I turned off some Intel auto settings because they were causing stability problems. It’s handling games smoothly without any hiccups.
Switching from the stock 2.5 with turbo to 3.8GHz without turbo improved my DOTA2 average frame rate by about 30fps.
On minimum settings, I see around 20fps improvement and 40fps on maximum. Overclocking definitely pays off, especially since this is my first overclock attempt.
It also outperforms the G4560 in Dota2, but in PUGBDOTA2 it lags by 5-10fps on average, while Xeon matches or exceeds it by 15-20fps on lower settings.
