Issue encountered while increasing clock speed on Ryzen 3400G iGPU?
Hello everyone, it's my spec:
cpu and igpu: Ryzen 3400g
Mb: Asus b450m-A
Ram: Corsair Vengeance LPX 3600Mhz CL18 (xmp enabled but with xmp it works as 3200Mhz Cl18 as my cpu can't handle 3600mhz, tried many different freqs and timings to make my own xmp profile
and now it works at 3400Mhz 16-19-19-35 with Dram Voltage 1.35 V)
ok, with every other Voltage setting on auto and every Gpu and Cpu setting on auto, when i increase IGPU freq from 1400Mhz to 1600Mhz (which is called Extreme mode in Asus bios), there is absolutely no performance gain in FurMark when i do a gpu test! both times (when it's on auto and when it's at Extreme mode which is 1600Mhz) i get 1658 scores :/ , and also when i set it to Extreme mode, when i open BIOS, the minimum temp of cpu is 57° ! and it goes up to 70° and cpu is not stable and when i start a cpu stress test, the system freezes and have to restart it.
Another thing i have to mention is that when Gpu freq is on auto mode, the Cpu Core Voltage in BIOS is about 1.32-1.38V which i think is ok but when i set GPU Freq to Extreme mode , the CPU Core Voltage becomes 1.52-1.54 V !!!! i guess it's high right?!
so, what should i do? any suggestion?
VDDCR Cpu Voltage in Bios is set to Auto and shows 1.45V next to it.
A single digit FPS boost isn't obvious unless you're closely watching the FPS counter on your screen. You can achieve the same FPS improvement even when lowering in-game graphics settings. This approach is much simpler and avoids putting your hardware at risk by either overloading it with excessive voltage or triggering thermal throttling. Additionally, the situation varies by game. CPU-heavy titles (like Cities: Skylines) generally don't care much about GPU performance.
Don't try to overclock your iGPU. Purchase a dedicated GPU and perform the optimization there. The iGPU is meant for basic operation and everyday tasks like web browsing. For gaming, a dedicated GPU is better because the iGPU lacks the power for modern games—especially if you manage to get it stable.
Thank you for the reply, but I don't have enough money to purchase a dedicated GPU so let's skip that.

Regarding the IGPU OC, if you watch YouTube videos of 3400G IGPU OC, you'll notice it performs very well.
So please, if you can assist me, do it because I need your help.
GPU costs have been elevated, often two to three times the MSRP. However, prices are now declining and the GPU market should stabilize by the end of this year or next. Also, top-tier GPUs aren't limited to the RTX 3000 lineup. Many affordable and high-quality options exist. For instance, the GTX 1660 Ti is excellent for 1080p gaming, and even the GTX 1050 Ti offers significant advantages over the Vega 11 you might own. See the comparison here: https://gpu.userbenchmark.com/Compare/AM...1440vs3649. Misleading data is common, so it's wise to reach out to the video uploader and ask about their methods. Ultimately, achieving RTX 3060 performance with a Vega 11 is not feasible.
yes, but i can achieve a 5-8 fps boost in games by using OCing igpu
Single digit FPS increase isn't noticeable, unless you are fixated to the FPS counter on top of your screen.
You can get the same FPS increase even when you reduce in-game graphical settings. This is far easier to do and doesn't put your hardware on a risk, by either feeding way too much voltage to it, or causing thermal throttle.
Also, it depends on a game. CPU bound games (e.g Cities: Skylines), care little, if any, about GPU.

Another thing is, that not all APUs are created equal. Your Ryzen 3400G iGPU (Vega 11) works at 1400 Mhz, but if you OC it to 1600 Mhz, iGPU works, but makes whole APU packet unstable, since OC is too much. Now, you can try with 1500 Mhz, since that's "safe" OC, but there is no guarantee that you'll gain any performance (extra FPS) out of it.
Next bloke in line, with their 3400G and Vega 11, may get stable OC at 1600 Mhz. While 3rd bloke in the line has it stable at 1400 Mhz and not even a single digit more.
But if you want a guide, here's one such:

Do note that in there, he just didn't OC the iGPU, but also APU itself and also enabled RAM XMP. Thanks to all three combined, he got the 15-20% boost shown in video.
overclocking the cpu wouldn't bring any benefit other than causing overheating. that's why I'm focusing only on the igpu part of the cpu, and I've also turned on xmp while making some adjustments to the RAM timing, as mentioned in my previous post. As I explained, when I increased the igpu speed to 1500Mhz, there was no improvement in performance, and in fact, it slightly decreased during FurMark tests.
Yes, i know. You even said that increasing iGPU to 1600 Mhz doesn't make a difference:
Like said earlier, there is no guarantee that iGPU OC gives any performance gains. Just because one bloke in YT got lucky in silicone lottery and is able to keep high-level OC stable with their rig, doesn't mean every single 3400G is also capable of that.
If you would have better CPU cooler, to dissipate the extra heat form CPU OC, you could see performance gain.
I'm concerned about this, but the present CPU frequency and power are sufficient and exceed what the GPU requires. I don't feel the need to overburden the CPU when the GPU is capable.
