[OC] Phenom II x6 1055T
Hello! I recently purchased a new graphics card since my previous one stopped functioning properly, and I bought a Radeon RX 560 OC 4GB. At first, I was quite enthusiastic, but once I began playing games, I noticed lower frame rates than expected for such a card. In certain titles, I sometimes achieved higher FPS on high settings compared to low ones—such as in GTA V, where the difference between low and full HD resolutions at 800x600 remained minimal, with FPS hovering around 30-40. This led me to investigate online and discover that my CPU was limiting the performance of the GPU. Given I have a Phenom II x6 1055T, it made sense to look into possible solutions.
Since I can't afford to buy another CPU, I turned to guides about overclocking. I managed to grasp some concepts, but it still felt challenging. I’m reaching out for your assistance as well. Could you help me resolve this issue? I’m hoping that adjusting the CPU’s OC settings could genuinely improve my performance.
Before we begin, here’s a summary of my PC setup so you can assess whether overclocking is feasible:
Configuration:
- CPU: Phenom II x6 1055T
- GPU: Gigabyte Radeon RX 560 OC 4GB
- PSU: Corsair TX650 [80 PLUS BRONZE]
- Motherboard: AsRock 970 Pro3 R2.0
- RAM: 16GB DDR3 1333MHz
I want to emphasize that I’ve never overclocked a CPU before, and my goal is to push this one up to around 3.5 GHz if possible. So far, I’ve only adjusted BIOS settings without saving them, and I’m cautious not to make mistakes. There’s something unusual in the BIOS—changing the FSB from 200 to 210 or 220 didn’t alter anything else, even the frequency. Also, I noticed I can adjust the multiplier, which shouldn’t be possible on a 1055T since it isn’t a Black Edition (1090T).
Here’s a link to a BIOS video:

I’ve also shared some CPU Temp details:

I’m open to discussing this further on platforms like Facebook or Discord, and I’m happy to provide more information about my system. I’ll also keep recording any BIOS changes I make.

The 3,5 only represents a 200mhz boost, which should be straightforward.
Check your CPU's safe temperature and voltage settings regularly.
Once you're sure you understand the process, return to BIOS settings.
General advice: avoid overclocking RAM while adjusting CPU settings until you reach optimal performance, monitor temperatures closely, refrain from exceeding maximum voltage, typically the final 200Mhz isn't worth the added heat and wear, use multipliers instead of bus widths.
It's unusual for a CPU to run at 200MHz while the system is under stress at 2.8GHz. Also, you mentioned wanting an overclock from BIOS instead of using AOD.
The highest turbo speed you can achieve for your CPU is 3300MHz. A difference of 3500MHz to 3300MHz equals 200MHz.
Ok then if 200mhz is not something that will make a difference, how much mhz do you think my system will handle?And why when i change the cpu frequency in the bios nothing else changes like it should...dram frequency and stuff?Not even the CPU Frequency per total modifies.
It looks like 1055t has a lock multiplier and can't be overclocked. The best option would be to overclock the HT and NB, but make sure memory stays within limits. My experience with AMD is limited to a 965be that had an unlocked multiplier and was much easier to work with. In theory, you should increase the HT and NB frequencies while keeping RAM within specs using a ratio changer. However, since I don't know your motherboard's BIOS, I can't provide more details. Still, I recommend trying a small adjustment in AOD and observing the results. Also, keep an eye on the motherboard temperatures as well.
I haven't overclocked a CPU before and AOD feels a bit too complex for me, so I'll start with the BIOS options. My motherboard doesn't have heatsinks, how can I monitor its temperatures? What software should I use? And I've read instructions about my 1055T, should I focus on OC with FSB instead of HT and only NB settings?
