OC my i5 750
Dear community,
I'm still pondering another issue regarding my old PC. I've upgraded the RAM, GPU, and the operating system is now on an SSD. Now I'm hitting the limits of my CPU, just as you mentioned. An i5 750 feels quite outdated. It doesn't cause any issues, but it restricts my GPU performance. With the new (used) GPU, instead of the similarly old GTS 250, I aim to push my older games to their limits. The main goal is to avoid replacing the CPU altogether, since I plan to build a brand-new gaming PC in two years. I just want this one to shine. Changing the CPU would be like altering its core—still functional but not ideal. So I considered overclocking the existing CPU. A friend helped me with this project eleven years ago, and we intended to boost it. The challenge was the Master Cooler V8 arriving late, so we delayed the attempt. Once it was available, we decided against it. Ten years have passed, but the CPU remains unchanged.
First question: is overclocking worthwhile? And if so, what steps should I take? This is entirely new territory for me, and I'm not getting much clearer guidance from online sources. The full build details are shared here.
And before you attempt to push your i5-750 to higher speeds, if you're okay with reduced performance and fewer cores, the i5-680 offers strong power that matches an i5-2500 in my experience:

It's also affordable since few people are aware of these options—I bought mine for just $15.
The i5 750 does not support overclocking. It only works with chips that have K or X at the end.
Thank you for the response. However, it's interesting to note how prevalent these items are online. Many individuals frequently increase their processor speeds to at least 3.6GHz.

I have closely followed the Linus overclocking guide and tried the same steps in the BIOS. There were some details missing, such as C1E and EIST. I turned on BCLK, adjusted the frequency to 185 and the voltage to 1.25, but didn’t go any higher. I also activated Load Line Calibration. Now I’m running at 3711 MHz with a temperature of 44°C while surfing and 50°C when playing CoD MW3. I chose CoD MW3 for evaluation because my Radeon software indicated the performance was only marginal, and I wanted to play the game on the best graphics configuration possible.
I’d appreciate some feedback on this. ^_^ This is my first overclocking attempt, and I wasn’t particularly interested in computers when I began. xD
@SamirD
The issue is that I really don’t want to modify the CPU. My goal is simply to boost performance and discover more about computing along the way.
Added: Now the Radeon software reports excellent results while playing CoD MW3, so that mission is complete. I’m now curious whether I did it correctly and if I can push it further. I use NZXTCam to track my CPU’s performance.
Don't worry about boosting the i5@750, it's meant for workstations, not enthusiast builds. I owned one, attempted overclocking in a frenzy, but nothing worked. In that earlier discussion
I already mentioned what you could achieve with your CPU on this machine. Consider swapping it for an Xeon 3470—it can be overclocked if the motherboard supports it.
I understand what you mentioned about replacing my CPU, but I also made it clear I didn't want to do that. Now I'm focusing on getting the best performance from what I have and gaining more knowledge about computers. As shown in the Radeon software, overclocking significantly improves the CoD MW3 performance—from just enough to excellent levels. You mentioned earlier that the CPU was a limiting factor. That's accurate, so I'm trying to find ways to work around it. It's also becoming harder to extract the maximum from it. ^_^
Exactly--single thread performance. It's why current 10 and 20 core cpus aren't the greatest in the single thread department.
