AMD C-50 CPU and 6250 GPU performance(Acer 522 review)

tested on the asus with c50 apu.. wonder why it isnt working on the acer 522.. they should share the same pll..

 

i was so excited

 

acer mobo sucks..its a budget brand so yeah, we cant compare it with a brand like asus despite the c50 have similiar price..asus 1015b has been ancient ago perform much better (clock increased with SHE) everywhere than 522, now i wonder why i bought this acer..

 

I have the Acer 722, but I'll tell you why we got the acer!

It was on sale for 199$ at target : )!

 

If you look at the Setfsb website, the author asks for entries for new computers that can be added in the next update. He needs the board, processor and some other information. So, I don't know how to find that out, but if someone can list all of the information that he is asking for, then in the next update, the Acer 522/722 can be added to the overclock program.

So, it's up to a smart user to bring that information forward. Perhaps the fact that we are the cheap netbook gang, means that we are cheap in our sophistication to get our product advanced.

 

You will likely have to disassemble your machine and get that info of the hardware itself. unfortunately.

 

Let me know exactly what information on the AO722 he needs. I'll open my netbook up and retrieve it for us.

 

google first...i think this kind of stuff should be published somewere already a522 is out for cca 2 yrs

 

Here's what the SetFSB website asks for,

Attention !!!
The information that SetFSB development needs is as follows.
a. the motherboard(/PC) name
b. the chipset name
c. the clock generator name

 

Here's what I can gather from my Acer AO722:

C-50 CPUID: 500F10
C-50 Part Number: CMC50AFPB22GT
C-50 Socket: FT1 BGA 413-Ball aka BGA413
C-50 Chipset: FCH1 "Hudson"
Motherboard Part Number: MBSFT020011180754B1601


Anyone else able to delve deeper? I believe the only thing I am not able to find is the clock generator name. It would appear as if we are ever so close to being able to overclock our netbooks!

 

Great! Let's email the author of SetFSB with this information. Of course you have a 722, while many of us have the 522. I wonder if there is any difference. I can't take apart my netbook as I am using it as a primary desktop machine.

I would email the SetFSB author but it might be better if someone such as Technocian would, considering that he has the prowess to discover such information. Can't wait to hear what the author says. In regards to clock generator name, perhaps the author can help find it?

 

is clock generator the same as PLL? if yes this would do

Try to get a look at the motherboard of your notebook/desktop. This is very easy on a desktop, not so easy on a notebook.

Just read the model of the PLL straight from the chip itself.

It's usually (but not always) near a crystal that says 14.318MHz.
I guess the most common brand would be ICS. Also SLG and RTM are very common.

ICS is made by IDT.
SLG is made by silego.
RTM is realtek.

Look for a chip with something like "ICS*****" or "SLG*****" or "RTM*****".

It comes in two main shapes, rectangle and square. Some might say a square is a special type of rectangle so just look for a rectangle

A lot of PLLs have 64 pins.

or you can see the detail here Podien's Shareware

 

!!!!! Progress!

 

anyone tried out the new acer fixpack yet?

Acer Support: Downloads & Support Documents - Netbook / Aspire One / AO722

Description: This update improves hard disk performance.

 

I'm not emailing the SetCPU author until we have all of the information; if anyone else wants to email him though, go right ahead. All we have left to figure out is the C-50 clock generator. A recap of information we currently have is:


C-50 CPUID: 500F10
C-50 Part Number: CMC50AFPB22GT
C-50 Socket: FT1 BGA 413-Ball aka BGA413
C-50 Chipset: FCH1 "Hudson"
Motherboard Part Number: MBSFT020011180754B1601

 

Makes sense. Excellent work thus far. Again, I can't take my netbook apart as it's needed for my work and beyond that, it's my only computer which is presently acting as desktop.

But if someone else could find the final piece of information, we all would then be able to overclock our netbooks in the next setfsb update.

Someone, stand up , take charge and sacrifice for the netbook community, showing solidarity with the common man, with his common needs and fire the torpedo of progress straight towards the looming shadow of anti overclocking wickedness!

 

well, I opened up the netbook, but decided to not completely tear it down, as that would have been an intense multi-level task, beyond getting the base unit opened. I am just not technically inclined enough to march through that circuit jungle.

However, I did fix a problem. If anybody has the problem of the screen going white, fading in and out, well it's not the screen itself but a connection.

When I opened up the netbook, I was able to expose a bundled black wire going from the board up into the lcd screen. What I did, via a youtube tutorial for regular sized acer notebooks, I took a piece of tape, wrapped it around itself and created a little rectangle tape plate that fit within the space next to where the power button is before the bundled wire, coated in a black sheathing goes up into the lcd screen. By putting the top part of the netbook body back down into position, it sandwiched the rectangle tape plate onto the bundled wire. That pressure solved the problem of the netbook screen going white. No more issues. I screwed the body back together and while one body screw at the bottom of where the power button is couldn't be tightened, the screen is as if brand new.

Good to know for those who have had this problem. So, if your screen is white, not a lcd issue, in regards to having what I was experiencing, fade out and with subsequent pressure around the lower framing of the lcd screen, temporarily fixing the solution, well it's now fixed.

Again, I didn't get to the underside of the board as it looked too complicated and the more complications, the further the risk, a risk that I could not take considering that this is my sole computer.

Anyhow, someone who may have an extra computer, I think the risk then would be lessened and it's rather straight forward. Take out screws, unplug ribbons and then more screws and the board coming off, thus seeing the underside, including the chip.

Sorry for the long message, but information can be helpful.

 

Here's the problem with finding the PLL/Clock Generator by the traditional method: You need to remove the CPU cooler.

On a desktop this is not a big deal and it kind of isn't for a laptop, it is just really annoying having to reapply the thermal paste and set everything back in. Google has proven to be fruitless so far, if anyone else has better Google Fu please attempt to retrieve this last piece of information we need.

 

make request on other hw forumus... from someone who already do apart video or some photoserial
hm or try to request this data from ACER support )

 

I got the 722 yesterday and found the exact ridiculous HEAT problem as Edible had had. I am wondering any of you tech savvy guys in this thread have experience with AO 722's CPU temperature issues.

I need to determine if this is a defect (heatsink?) or a common problem in AO722 because I have only 9 days left to return it to the computer store if it is defective. There is no Acer repair center here in Canada and I don't want to spend money mailing it to the U.S. - the high shipment fee would be too much for a machine that cost 200$.

Acer CS told me the temperature range under normal usage should be 50-80C. But mine can easily get over 80 within less than one min in any standard tress test. It remained over 80C for half of the Office 2007 installation (no other softwares running). Once I played a 360P video in frame mode with firefox, the cpu temperature remained 87C most of the time and even reached 91.5C but the machine didn't shut itself down! With IE playback (non-HD, not full screen) the temperature stays around 73C.

Yes, I have the latest Bios installed - v1.08.

Please help me. Thank you.

 

this machines heats up...
yu should lower voltag with that tool brazostweaker
and use balance power plan...nothing more yu can do really

 

interesting answer... I was coming over here to ask you 522/722 guys a question, and it relates to the issue immediately above:
Have any of you done a proper thermal-paste job on your APU?
and if so, what were the results?
any tutorials on that?

 

Thank you, Krishna.

I did undervolt it yesterday. It worked. At first I accidentally found that I could lower the processor's power in Windows - it seemed to work for a while but then everything went hot again. I guess I happened to test on some youtube video that supports GPU (?) which made the CPU cooler. I found some low resolution videos make the machine hotter than HDs do.

Then I happened to read some deal reviews on another website and noticed someone mentioning "undervolting", which I had never heard of before. Eventually I found the software "brazostweaker" and the spreadsheet for AO722. I am using the P0: 0.9. P1:0.75 setting (provided and tested by others) in the sheet after testing it on my machine with intelburntest standard and high level stress test and videos.

I don't think I will return this netbook since it works well now. It boots Windows 7 HP within 50 seconds and I like the 500G HDD and 4G RAM in a light-duty machine.

Do you think I should try your setting (in 522) for my 722? I read your old post. Your setting seems more aggressive. But each model needs different settings. You seemed to take another route? -- P0: 0.8750 vs. 0.900. P1: 0.7875 (800Mhz) vs. 0.750 (500Mhz) Does 800Mhz (rather than 500Mhz in mine) for P1 allowed you to set P0 even lower? Or this setting only make sense for 522? I have no idea how P0 and P1 relate to each other. Is your combination cool the CPU even better theoretically?

P.S. 1) Where are AMD C-50 APU drivers? (which Wiki page?)
2) After opening AMD Vision Engine Control Center in system tray, I can't see "Performance", "CPU Power", and change "on battery" CPU Processor speeds to 800 mHz.
3) If I find it, should I put in 500 mhz? (does "80 divided by - 8.0 8.0" means 500mhz?)
4)I don't know if at 500mhz the performance is compromised, should I raise it to 800 mhz?
5) Do I still need to configure the processor power in Windows after undervolting? (now minimum: battery 0, plugged in 0. maximum: battery 50%, plugged in 80%)

 

Something new I learned. You can run multiple displays on the netbook. I have a 24 inch monitor running from the hdmi and my 32 inch lcd television is running off the vga. I was under the impression that this didn't work so , well it works.

You can run multiple monitors. I have not tried to see if the netbook screen will run as well, adding up to three monitors, I can't do it right now, as I have an external harddrive resting on the lid downloading content, but I will test that later.

If you can have three displays at once, I would say that this netbook is even more radical, considering the industry standard for netbooks.

 

"only" two outputs ! - 3 not possible

 

Ah, three being the netbook screen itself, not a "monitor". Let me try it right now.

No, the netbook screen stays blank.

Anyhow, yes two monitors, one from hdmi, the other from vga can both operate at the same time, which was something thought to not be possible before.

Either a driver update with the catalyst package or whoever had posted that it was impossible had not gotten it correctly.

 

what driver does anyone use
I was using 12.6 then 12.4 and they both made my screen start turning white, formatted and installed 12.3 and now runs fine but games stutter a bit more.

 

I am using 12.6 but I cannot access many parts of catalyst, including manual settings for graphics. I am getting good performance with this driver though and my graphic settings are passed along from driver to driver.

In regards to the screen turning white, I have not had this experience, except for when a cable which runs from the motherboard to the lcd screen gets dislodged and a flickering white screen is a result, which can be fixed with a bit of cardboard to secure the cable.

 

curious: did you manually install the 12.6 display driver?
there's a bug re: E-series that 12.6 installer misses the hdwe and flies through, installing everything but the vid/graphics driver but does not alert the user. checking around, many e350/e450 pilots thought they had 12.6 installed only to find a backrev ...
I posted a trouble ticket to amd but no answer.

12.7 has a nasty bug with Flashplayer of all things. lockups

 

I think you're onto something, either way its fine now.

 

Interesting, as I have a c-50 with the 6250. What's even more interesting is that for some reason, my gpu, after a prior version of Catalyst, became a 6310, of course only in name which shows up in catalyst, gpu-z and computer information as 6310.
Perhaps a e class driver had lodged itself? if possible? into my setup which would then cause the issue that you just described. I will definitely switch back to an earlier catalyst.

In regards to your question, I did manually install 12.6 after unistalling 12.4


Thank you.

 

latest drivers shows 6250 as 6310...
also 12.6 not installing for me, i got12.7-8rc1 !
and for those who got badly stretched screen or some problem on external displays and projectors, try to manualy increase refresh rate! (itworks for my problem)
anybody tried win8 final? its worth it?

 

same here, except on E-350. tried every trick to get 12.6 loaded but it will not. reported to amd almost 3 weeks ago now.

with 12.7 I got hard failures [black screen] using flash, high def, external monitor. repeatable.

 

I have emachine e443 with c-50 and amd 6250, 3 GB or ram and I can't seem to be running any newer Linux distro (Ubuntu 12.04, Mint 13, Suse 12.1) without lag. Do you have this problem?. Currently i'm using Windows 7 and it runs perfectly.
Another question, if any of you have this emachine laptop, could you tell me you temperature on it?

 

CPU-Z????

Also has anyone tried 12.8 drivers

AMD releases Catalyst 12.8 | bit-tech.net

 

I have 12.8 and its working perfectly fine for me. it also fixed the 6250 seen as 6310 problem and im not too sure abotu this, but i think im having less video lag with this update (ao522 bz499)

nvm youtube video's randomly freeze while the audio goes on, and it only catches up with the audio if i pause it.... then play again

 

well been using 12.8 for a month, smooth as bananas.

I just wish there was some magical C-50 tweak that would unlock the CPU but

 

I tried linux - Lubuntu and it's great, only problem is i can't play youtube in fullscreen (not even 360p). It becomes choppy and laggy, but on windows 7 i can play 1080p without lag.
Do you have same problem with youtube when using linux?
I have AMD c-50 cpu and 6250 gpu with 3 GB or ram.

 

Well i have read thought the entire 169 pages and it`s great info, I have an 725 on order with an C-60 , I have an 4GB crucial so-dimm and a 60GB SSD to put in.

I previously had netbooks with Intel N2800 and N2600 , the WEI of the N2600 for gaming was only 1 , but it played fullhd video fine., but gaming was out of the windows, so it`s been returned.

So expect a few posts in a few days

John.

 

Well still waiting for my 725, I expect it Wednesday, the good thing about the 725 is it`s easy to upgrade the hdd and ram as the bottom cover just slides off and has only one screw.

Does the heatsink look more substantiation on the 725 compared to the 722,also the back cover on the 725 has two extra vents, is the little square where the cpu is? , maybe i can add a heatsink.

The photo below is a comparison of the 722 and 725

John.

 

What OS are you using on AMD c-50 with 6250 gpu? I've tried W7 and XP and i think on xp it doesn't use full potencial, somehow it's not as smooth as on W7.

 

XP is only directx9 and 32bit as the 64bit is supposed to be buggy, also no trim if you want to use an ssd, Win7 Starter is limited to 2gb of memory even though your motherboard will support 4gb, so if you can install the full Win7 32bit or 64bit you can use the full 4gb, 64bit is supposed to run faster than 32bit, see link below.

Super late to the party! On Friday I received a refurb'd ao522 shipped for $200 USD! Kingston HyperX 3K 120GB SATA III SSD and Crucial 4GB DDR3 1066 CAS7 arrive today when I get home from work.

I have been an active PC user and system builder since the late 90's. My motto would be thrift and function before form and flash. I have never actually had a personal laptop. I have had a few work laptops over the years and some laptops for my wife... so this little beast is more exciting than it probably should be.

I had bought a refurb'd Acer ao722 for $275 a few weeks ago for my wife. This was to replace a ASUS Eee PC 1215N that she dropped and broke the metal hinge on. The 1215 is now a dedicated bedroom HTPC.

I was impressed with the rez, big RAM capacity and GPU on her new 722. But I thought: "that thing is just to big for my preference." I did a little searching and eventually realized there are not too many 10.1" 720p systems in existence. So I purchased one of the only units that I could find.

I am sort of dreading the frustrating tear apart/HD RAM install tonight, but I will hopefully report back with great success.

Loving all the information in this thread. Thanks to everyone for the documentation.

Edit: forgot to add one thing... I have only built PC's with AMD chips. For many years, AMD was not a serious mobile competitor. I am pretty happy to keep my first personal portable in the family.

AMD's of my past and some present: K6-2 350, k6-2 550 (chomper), duron 750 (spitfire) oc'd to 1G, Athlon 1333 (thunderbird), Sempron ? (can't remember but it was my first x64), Athlon 64 2200 (venice), Athlon 64 X2 4200+ (2x Brisbane), Athlon 64 X2 5000+ (2x Brisbane), Athlon II x3 425 (3x Rana)

 

Good to hear man... Take care with the screws. I had one that was way to tight and the screw was stripped.

 

Success. The keyboard popped up rather easily from below. RAM and SSD worked immediately. I had grabbed drivers from the OEM folder ahead of time, so getting online was no problem. Windows update offered me an ATI driver, but i skipped that and grabbed the latest from AMD. I am using a old version of win 7 ultimate, so I had to take all the updates. That was a very slow and CPU intensive process. I hit ninite.com to get most of my apps and utilities. I am installing a bunch of indie and lowend games from Steam right now. I still need to ru that command and shrink the wsxs directory a bit. Overall, having some fun.

Bearclaw, I am only about halfway through reading this thread. Early on I think you posted some SSD benchmark numbers that had you disappointed. Did you ever come to a conclusion on that?

 

Hmm that was a long time ago but I think someone else also posted their Samsung SSD scores and it looked like the 4k scores were about half of what they're supposed to be in other benchmarks. The write speed also seemed to be lower... But I don't really notice it because at this point the CPU is the bottleneck not the SSD.

Edit: See these comparisons: I know they're not the same size SSD but the results are pretty different:

Hi.

I have an 725 with the c-60 , I am looking for a gadget that show the correct cpu frequency, i am currently using "all cpu meter" but it does not show the turbo of 1300MHz , and show a max of 1000MHz

Thanks

John.

 

it only turbos when it's stressed?

 

I just put an 8gb in my 725 and it works great, it`s a bit of a overkill but at least it works

John.
