Question Issue booting after changing cpu base frequency

[thisisaac]

I recently change my gpu from gtx 650 1gb to the sapphire rx570 4gb. Prior to changing it, I was able to change the "CPU frequency", originally it was at 100, I was able to change it above that value. However with the rx570 4gb I wasn't able to boot , i had to clear the cmos to get it to boot.
CPU: Athlon II x4 641
Motherboard: GA-A55-S3P rev 2.1
Ram: hynix ddr3 4gb
SSD/HDD: micron 500gb ssd
GPU: Sapphire RX570 4gb
PSU: m2 silent pro cooler master 620w about 8 years old
Case: 1st player fire dancing v6
OS: Windows 10 pro . version 2004

We're going to need more information. Please include your system's specs like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Case:
OS:

Include the age of your PSU as well. Did you uninstall your Nvidia GPU drivers(using DDU) prior to removing the Nvidia GPU and then plonking in the AMD GPU?

That changed FSB clock which also raised RAM and PCI/PCIe frequency which GPU didn't "like".

i did uninstall the Nvidia drivers before replacing the gtx 650 with the rx570

Are there other way to OC my cpu? changing the multiplier and voltage dosen't affect any benchmark performance. But CPU-Z shows 2992.32mhz when i change the multiplier to ×30 from ×28

CPU frequency=multiplier*FSB. Those couple hundred MHz of OC is not going to change much performance and even less if CPU hits higher temperatures because of it.
Only real way to OC is with multiplier providing you have good enough cooling. You can tune it a bit more with FSB but if your BIOS supports it and you set PCIe and memory bus to static 100.

For some reason after swapping out the gtx 650 with the rx570 it doesn't allow me to change the FSB, sadly in the bios i do no have the option to change the PCIe frequency. But the weird thing is before i took the gtx 650 out, changing the FSB was possible. I changed it from 100 to 110 and my benchmark on cinebench improved quite a fair bit.

Raising the bus will adjust other hardware clocks at the same time (eg. memory, pcie). You need to reevaluate your OC stability since you have changed hardware. I suggest OC-ing using bus x multiplier at the same time to get better result, it's always the multiplier that gives more than the bus as the bus causes more stability problems than the multiplier AFAIK.


EDIT: I'm not too familiar with FM1/FM2 cpus but I have Athlon and Phenom AM3/AM3+ socket.. make sure it's unlocked because if it's not you'll be relying too much on bus overclock instead of multiplier, that'll lead to stability issues for sure if you get too far from the stock frequency.

I have a Phenom II x4 955 Black Edition (quad core) and it's unlocked that's the reason why I can freely overclock my CPU up to 4.0+ if i want.

At the same time I have an Athlon II x2 255 which is not a good overclocker and is not an unlocked version. That's why it relies too much on bus overclock and doesn't get too far from 215 - 225 times the base multiplier. which is around 3.3 - 3.4 as a result.

I tried raising the multiplier to ×34, on CPU-Z shows 3391.30mhz while task manager constantly shows 2.78ghz . When i tried to benchmark using superpi , geekbench or cinebench i see no improvement at all. The max i could bump it to was × 47 which too, did nothing. However the thermals increased but there is no performance boost which is confusing. ps i did increase the cpu. nb , ram voltage.

Based on techpowerup your CPU got a locked multiplier. Which means your CPU is not OC friendly.

BEST SOLUTION: Upgrade CPU.
Here's your motherboard's supported CPU list. I would suggest choosing the A-series, just update your BIOS to F6
https://www.gigabyte.com/Motherboard/GA-A55-S3P-rev-11/support#support-cpu

Alternative Solution: Dump your current build and buy a Ryzen 3/5 instead. Upgrading these days are not really that of a recommended thingy and the highest upgrade you can find for this board is absolute trash in performance compared to am3 and am4.

just curious, how was i able to change the multiplier if its lock? Like how does CPU-Z shows that I'm running at a higher frequency?

If it's CPU that's locked BIOS can't do anything about it.

what do you mean? I had the option to change the multiplier to a maximum of ×47. After changing it CPU-Z reports the frequency that i changed it to (eg 34 × 100= 3400mhz) . Shouldn't it remain at 2800mhz?
