Method for boosting AMD A8 7600 Kaveri and its benefits are worth considering.
Hello community,
I've looked through several discussions but haven't found a clear answer on how to overclock my Lenovo H50-55 PC, model 90BG001LUS.
Here are the details:
Windows 8.1 x64
8 GB DDR3
AMD A8 7600 Kaveri w/ Radeon R7
3.1 GHz (3.7 or 4.1 Turbo?)
PCI-Express motherboard
So far, I've tried:
- Downloading AMD Overdrive and searching YouTube, but nothing solid...
My aim is to squeeze a bit more performance from my APU without buying a cooling fan, etc. I play mid-level games and would love a slight boost in FPS.
I don’t have enough experience to tweak voltages myself. The “auto overlock” option in AMD Overdrive isn’t working.
Using the BIOS seems like the best path, but I’d appreciate a clear, step-by-step guide.
Thanks for your help!
You might be limited in overclocking, depending on the motherboard. That said, here's a general guide to Kaveri http://www.hardcoreware.net/kaveri-7850k...enchmarks/ While not the exact chip, it might help guide you in the right direction.
Sorry I can't help much. I've overclocked both AMD FX CPU's and Intel i5/i7's, but never an AMD APU.
The A8 7600 is a secured card that cannot be overclocked. Cards that allow overclocking are marked with an 'k' at the end. The specific model needed for overclocking is the 7650k.
The AMD A8-7600 can be overclocked by adjusting the BCLK. I've set Mine to 4064MHz (4.0GHz) and RAM at 2080MHz, but it fails to exceed 4.1GHz during boot and freezes midway through Windows startup. At 4064MHz (4.0GHz) with a voltage of 1.334V and Turbo-Boost off, the BIOS reports temperatures above 100°C. I'm using a Cooler Master Hyper 212 Evo, which maintains idle temps around 35°C and under load between 58-62°C. The CPU remains stable.
Only try overclocking BCLK if you are confident with your actions.
What speed does your RAM reach?
From my perspective, you have two choices (the latter being free).
1.) The fastest and simplest method to enhance the iGPU (R7 graphics) is to increase the RAM speed, since the VRAM for the APU comes from your RAM. For example, RAM at 1866Mhz instead of 1600Mhz will slightly improve performance and FPS.
2133Mhz could be effective from an original 1600Mhz configuration.
2.) Additionally, I own an A8-7650k and in the BIOS I have activated Dual Graphics. Now I don’t have a second GPU, but this allows me to switch the RAM capacity used for the APU from 1Gb to 2Gb – doubling the VRAM and significantly boosting gaming performance.
Check your BIOS if this is possible; it won’t cost anything, just adding an extra 1Gb from your RAM, leaving 6Gb for Windows and the game you’re playing.
I strongly suggest trying option 2, adjust the BIOS settings, and take some notes so I can guide you through the process.
Enjoy gaming!
The AMD A8-7600 can be enhanced through adjustments to BCLK. I’ve managed to push Mine to 4064MHz (4.0GHz) with RAM at 2080MHz, but it fails to exceed 4.1GHz during boot and freezes midway through Windows startup. At 4064MHz (4.0GHz) with 1.334V, Turbo-Boost is turned off because it raises the voltage to 1.5V, leading to temperatures above 100°C in the BIOS. I’m using a Cooler Master Hyper 212 Evo, where temperatures remain at 35°C idle and around 58-62°C under load. The CPU remains stable.
JCLDJB asks if you’re certain about adjusting BCLK. Could you confirm the exact MHz of your RAM? I own 1600MHz, but my motherboard only supports up to 1866MHz—this would likely add only a few frames or not be worth it.
I see two possible paths:
1.) The fastest method is to increase RAM speed, since the APU’s VRAM comes from your RAM. Switching to 1866MHz instead of 1600MHz could slightly improve performance and FPS.
2.) Alternatively, I have an A8-7650k and enabled Dual Graphics in BIOS. This allows changing the RAM size for the APU from 1Gb to 2Gb, effectively doubling VRAM capacity and significantly boosting gaming performance. You can check your BIOS settings for this option—it’s free and won’t cost anything.
Just take a look in your BIOS, and let me know if it’s possible. Enjoy gaming!
Certainly, please consider obtaining the digital manual from the manufacturer's official site. Upgrading BIOS versions can be quite time-consuming—typically manufacturers release updates every 1 to 2 months at most. Which motherboard are you using? What is the model?
I currently use an MSI board, and their BIOS setup is quite convenient. Under the main Settings menu, just above the overclocking option, there’s a GPU section that appears when I enable Dual Graphics. This lets me switch between 1GB and 2GB bandwidth options. It seems this feature is only available on boards that support Dual Graphics, which many do, though not all (please let me know if you have doubts).
Could you confirm the make and model of your motherboard? I’ll look it up and assist further. Also, does your system use a single 8GB RAM stick or two? This difference significantly impacts performance—two 4GB sticks versus one 8GB stick makes a huge difference.
Lastly, what is the RAM’s frequency? Anything below 1600MHz isn’t ideal.
Yes, consider upgrading and downloading the digital manual from the manufacturer's official site. Thanks, I'll give it a shot.
It’s really short to wait another year for BIOS updates... if the company is reputable, they usually release 1-2 per month, though sometimes less or more.
Which motherboard are you using? I own a Bantry CRB Lenovo board, model 31900058 STD, PCI-Express, as listed in CPU-Z.
What’s the make/model?
I’m using MSI, and their BIOS is quite solid. The settings are under the main tab on the upper left, just above the overclocking option. I select GPU there, and once Dual Graphics is enabled a new tab appears (previously hidden), letting me choose between 1Gb and 2Gb.
It would only be available if your board supports Dual Graphics, which seems common but not universal (please confirm).
I’m pretty sure my board doesn’t support it.
Could you please verify the motherboard model? I’ll look it up and assist further.
Also, is it a single stick of 8Gb RAM or two sticks?
I have one 8GB stick. I tried the 4x2 configuration, but if I can’t push beyond 1866MHz, it doesn’t seem worthwhile.
This really matters — for example, 1x8Gb versus 2x4Gb makes a huge difference; the latter will boost APU performance significantly compared to just one stick.
Lastly, what is your RAM’s frequency? Anything below 1600Mhz isn’t ideal.
I have 1600 MHz 8GB single stick.
I haven't looked into the motherboard's specifications yet, but I can already suggest some steps you can take right now to boost performance.
Consider adding a second RAM module and enabling Dual Channel.
Imagine a typical PC with a dedicated GPU: it uses two kinds of RAM—the GPU VRAM and the CPU’s main memory. Since both the CPU and the integrated graphics on your AMD board are competing for the same 8GB of RAM, your performance is essentially cut in half.
Think of a single-lane bridge where both the CPU and the graphics card try to cross at once; you need another bridge so they can move independently.
From my experience, I had the same issue with my setup—my PC came with just one stick of RAM. The results were terrible, far below what benchmarks showed possible.
I purchased a second identical 8GB module directly from the manufacturer to guarantee compatibility. Instantly, I noticed a significant improvement, not because the system needed more than 4-6GB, but because having two channels improved data transfer.
This is your main limitation.
Don’t worry about frequencies yet—focus on this first. A second identical 8GB RAM stick should cost between £30 and £40 if it’s standard, and you’ll see the difference right away!
I’m confident others agree with me, and most reviews confirm this setup works well.
Let me know how it goes.
