Overclocking a HD5450

post #1 of 19
Thread Starter 
Hi All,

I have here an other rig than stated in my signature.
This rig has a AMD Athlon II X3 440 processor.

It has also an ATI graphics card, the Radeon HD5450.

To the point: Is it worth to overclock this card?
This for some better Folding & Gaming.

I hope someone can help me out.

Greetings, Rik

You'll probably benefit a little from over clocking both the CPU and gpu. And see where that takes you.

I have one in a shoebox full of scrap electronics, and I can tell you, it is not meant for gaming. Only use it for backup videocard and benching.

Okay, thanks both for your message.
I don't have the money to upgrade, unfortunately.

But it ain't worth overclocking??

It is if you are trying to save money. My gf has that card. Honestly it is a very impressive card considering the reviews were terrible. I have it OC to 715 core 685(max) memory. Used the official over clocking method for afterburner. Max stock in CCC is 695 core 685 memory. Plays wow very well.

Oh and I added a fan to keep it cooler. This 5450 only had a HUGE heat sink.

Hi Durquavian,

Thanks for your message.
But what do the numbers in your first post mean?

I mean 695, 715(max) and so on.

I'm a new in to the Overclocking "scene" wink.gif

Greetings, Rik

boy is that a loaded question, lol.tongue.gif First to simplify things, download MSI Afterburner http://event.msi.com/vga/afterburner/download.htm. Once downloaded and installed open the application. In Afterburner you will see some lines:

Core Voltage (cant do anything with this, and prob don't want to. Uses your board pci-e power)
Power limit (cant do anything with this either)
-CORE CLOCK(MHz)--- this is what you will change
-MEMORY CLOCK(MHz)--- this you will change too

When you first pull it up it will be at stock clocks, for my gfs it is 650mhz core and 533 memory. This is your baseline. Generally you change the core in increments of 5mhz and test stability( I will give you advice on programs for this later.) If stable up another 5 mhz. If not then go back down to last stable clock and move to memory clocks. Again increase in 5 MHz increments till you find highest stable clock.
OH and don't worry if you overclock too high it doesn't hurt anything generally, Only OCing voltage can do permanent damage. Watch the temp, it will be on one of the graphs in afterburner and it is shown in both tests you will use. 75C is the max temp you want to see at any time in benching, though to be honest, I don't think a 5450 can get to that temp. It uses board pci-e voltage and it is pretty low, and the wattage(power consumption) is only 19 watts, most cards like mine are 110 watt or more.

If your 5450 has a fan then this will be easier than if you have one like my gfs, just one huge heat sink. I added a fan blowing air on the fins of the heat sink. Most stability issues arise from excessive heat.

Programs to test with:
KOMBUSTER- you can download using same site you got Afterburner from.
HEAVEN BENCHMARK: http://unigine.com/products/heaven/ MAKE Sure you use lower graphics on the menus in this program, it is more intended for high graphics cards. But this helps test memory stability better than KOMBUSTER, which is a great test for GPU(aka core).

AND lastly the best test is the actual game or GPU heavy program that you are gonna use. My 7770 can pass both programs I listed above then when I play SKYRIM it locks up, hence giving me my TRUE STABLE clock.

BUT PLEASE just TAKE YOUR TIME. Nobody finds that perfect setup in 10 minutes. Most of us take days to weeks to find perfect OverClock. My advise to you is find that max as close as you can, then back it down a little for safety measure. No point in pushing your luck.

My Gfs 5450 is at 720mhz core and 695mhz memory. She plays World of Warcraft fine and to be honest it looks pretty good. It wont likely set any records but I am impressed. Seeing how it is considered trash by everyone else. But hey, it will get you thru till you can get a newer one.


If you feel like trying it after you have practiced with the above steps and you find you have maxed out as far as you can with AFterburner and the only way youll get to 720mhz like my gf, then check out this thread--> http://forums.guru3d.com/showthread.php?t=370201 .

I check these forums enough, so if you need more detailed help just ask. Over clocking is a tedious and enduring task. It is more like an artform, takes a great deal of patience to create that masterpiece.

AND keep in mind 95% of what you find on the internet is Opinion and 5% is FACT.

Durquavian has it pretty much right, although I would add that you could probably bump it up 50mhz the first time and then slowly go up from there. It's only to save time, and just going up 5mhz at a time wouldn't hurt.
