Question No Diffence after Apu OC

[mandeep57]

i have R5 2400g
i was trying to OC igpu
base was 1240mhz
And i OC it to 1340 mhz
then i tested FPS in Furmark
But both test from Base clock and OC are same (1494 points 25FPS avg.)

You can't really expect much or anything from 100MHz. Probably spent it all on heat.

but PC Crash when i go higher
cpu is at base speed
When i go for 1400mhz PC crash...Do i need to Increase Voltage too?

Yes, most probably.

ok i did it to 1500mhz in Ryzen Master with voltage 1.2 but still no difference in Test

annd after restart its back to base speed 1240mhz

but when i do 1500 mhz in Bios ...PC crash

You may need up to 1.5v for that high OC. Maybe your MB can't supply enough power or it's hat throttling.

my motherboard is Msi b450 Pro Vdh plus
what you think?

I also found this post on internet

When overclocking the integrated graphics core on both APUs, rising through the frequencies, we experienced an anomaly or 'black hole' between 1350 and 1500 MHz. Regardless of the settings, there was a clear issue in the system.

While the system would boot at these frequencies, the combination of overclock and drivers caused random reboots of the test system, constant and consistent crashes during gaming, and Windows Crash Reporter stating a 'Video_TDR_Failure' of the atikmpag.sys process. This error is usually an indication of a faulty or corrupt graphics driver, but in this instance, it happened across multiple systems with three different motherboards and operating systems using the AMD's Adrenalin Edition 18.5.1 WHQL drivers (the latest at the time of testing). The issue bestowed itself regardless of the GPU driver used, or BIOS revision on any of the motherboards tested.

At 1500 MHz however, the issue went away. Our experience is not unique - other professionals in the industry have experienced similar issues. We have reached out to AMD about this issue and will update when an official response is received.

Integrated Graphics Frequency	SoC/iGPU GFX Voltage

1200 MHz	1.15 V
1250 MHz	1.15 V
1300 MHz	1.15 V
