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

My Asus is a 40W adapter outputting 19.1V..

 

Acer AC adapter with US plug

 

If only genuine ones were equivelent price in the UK it'll be a cheapo ebay job for me

 

Any help on the power saving would be great, mines fully charged in power saver mode and its showing 5hrs usage left, i was looking at one on ebay before I bought mine and it had a photo of it showing 7hours+ on 93%, i know its not to be believed fully but thats quite a difference....

Edit that, just used that Brazos tweaker to undervolt the cpu to 0.9v when at 800mhz time immediately has shot up to 6hr28min whats the lowest v that can safely be used?

 

brad it depends on settings, if yu lower cpu, brightness it should be more ...

 

Thanks, ive settled with p0 of .9v and p1 of .8v seems stable so far and reported battery life has jumped up a considerable amount

I noticed in the service part it has a box to make custom p state settings permanent, what does that actually mean, is it just sent to a startup service?

 

What does the voltage to your cpu have to do with the brightness of your screen???
It just depends on your cpu (they all have a different tolerance), I couldn't go below 0.9v for both p0 and p1 states but others have gone significantly lower and stayed stable. If you want to try going lower, just go step by step and stresstest with something like orthos to see if it's stable.

 

brad ..if its stable make it permanent than..that means it will be settled witch each system start...
finraziel... battery life and lcd bright. has much to do....

 

Done, just currently playing a wmv file on repeat to drain the battery for battery life test

 

Hi bradmax,

since every CPU is different, each has its own minimum voltage at a certain frequency. You can find the lowest setting only through a few iterations.

Start from were you have the voltage now and lower it one step. If it doesn't immediately freezes, run Orthos for a while. If everything seems stable, go down once more and do stress testing again. Make sure, while running Orthos the CPU is in the changed PState.

If you lowered too much, your netbook will freeze or will throw errors in Orthos. If that happens, bump up the voltage 2 steps for having a bit of margin.

Check out the Wiki for more.

Hope that helps,

We should have a section for us to post our frame rates in games.

 

Hmmm

When using Brazostweaker

After you applied your voltage do you always have to run the tweaker every startup???

 

Ah I see, you were talking about the batterytime, looked like you were answering his question as to how low he could put his voltage...
Shadow, by default you have to set it every time but it has an option to install a service to apply the setting automatically when you reboot and it's permanent then. You better be very sure it's stable before you set that though.

 

Click on Service .. , click on Update, then check "Make custom P-state settings permanent" and finally hit "Apply", but as Finraziel said, be sure all your PStates are stable.

You can read through all that in the Wiki too.

Greets,

I already did that. So I guess that everything I did is correct

 

Hi,

Just wondering if its normal for the laptop buzzer to make a noise when plugging in the AC adapter, ive only had mine a day or so and cant really remember if it did it when I got it?

Cheers

 

i noticed in brazostweaker, under the status tab the D18F3x15C vidL1 and vidL2 are changed accordingly when adjusted in brazostweaker. however vidL3 and vidL4 are always at the stock vid of 0.85v for me. could that have something to do with why the nb vid cannot be changed?

 

It is normal

 

Good point. I can try to create an experimental version.

you guys that are going for top frame rates, what's your baattery life?

 

Now that the c-60 is officially out, is there a way to simply buy the new apu and mount it on the netbook motherboard? Would they sell them individually?

What a pain, to buy a whole new netbook.

I wonder if windows 7 would have to be reinstalled? Or could you simply plug in the harddrive and ram, and it's just as the old one.

For that matter, I would just buy the e-450 at that point, in which case, could the harddrive swap be so simple to have everything intact.


On second thought, I am happy with the c-50 and as long as I can play oblivion with large textures, bloom lighting, ax2, 1000x600, then who cares.


Still would like those questions answered if anyone knows. thank you.

 

Sorry man, this APU is in a BGA package, which is soldered onto the motherboard. It can't be replaced.

-witteks

 

that would be awesome man. it seems that the guys at biomods forum think its not possible to patch in vid and fsb adjustments into the bios for the ao522. so we're all out of luck for any sort of overclocking, or even gpu underclocking/undervolting. that is very disappointing to say the least. this gpu cooks, and needs to be brought down a couple notches. I had nearly a 30% overhead on my stock cpu vids, which leads me to believe the gpu is just as bad.

so basically, you're our only hope lol. keep up the good work. let me know if you need me to test out any software. i'd be glad to. look into that l3 and l4 vid issue. i'm sure that will lead to positive results. I wish I could contribute in a more meaningful way. but i have no technical training. I'm just a good problem solver with a terrible tech addiction

 

It isn't measuring the FSB right. It isn't fake.

 

c60 is nothing to be jealous about , its same chip as c50 and "turbo" is only on paper i doubt it will better performance, i think it will have worst perf. than normal mode...

 

It increases the clockspeed of both the CPU and GPU part, how do you figure it would be slower?

 

Word on the street is that the c-60 is actually repackaged stolen intel technology, specifically the pentium 1 chip. Supposedly it can play
wing commander.

 

turbo mode is turning off 1 cpu core...and yu cant get better performance with one core...maybe in some really old applications/games

 

Look --> http://www.notebookjournal.de/storage/show/image/image4e527a10ce5ec

 

seen this?
Did some benchmarks with the E-350 and C-50 APU's - Overclock.net - Overclocking.net

is that actually a c-50 chip in there????
400mhz gpu upgrade for free???

 

I believe, this was discussed and checked in the SlickDeals forum . Actually the C-60 is really a different chip and a C-50 can not just be updated to get a C-60! The video was just done with a C-60.

Shame

Overall im pretty happy with my 522, ive upgraded the ram and hdd to the hybrid ssd/hdd performance isnt bad, still getting a bit of lag from opening a webpage till I can type other than that its pretty good, will be good when I go on holiday in a couple of weeks

 

i thought that was the case. im grabbing at straws over here lol. any luck with the "experimental" version of brazostweaker on those two other nb states not changing?

 

bump its c60
so turbo mode is 2cores at 1.3ghz ?

 

ACER ASPIRE ONE 11.6 C-60 6290 250GB WIN7 AO722-BZ454 | eBay

he's lying?

 

Most definitely. The BZ454 version of the AO722 has the C-50 and is not manufactured with the C-60 at all.

If Acer were to make a 522 or 722 with the C-60, it will have a new subversion and not an existing one. So yes, that dip is lying.

 

Well if your local to the seller you can pick it up, so you could check before you buy, i see no reason for to him to lie tho and there is another seller stating the same item and spec and even goes on to say that the box says c-50...?

 

its for real, actually.
unannounced, they are shipping C60 units out apparently since late july [end of july]. check the VERY busy slickdeals thread, last 10 pages or so...

 

just wondering if my momentus xt hybrid drive is being bottlenecked by the cpu? I didnt try it with the 5400 drive that came with it but ive just one below in a faster lappy with less ram than the 522 and the difference was pretty noticble

 

i dont know why new c60 has lower WIN WEI SCORE...but its true...lower cpu and ram score....hm

 

Your source? Most people from the SlickDeals forum reported higher scores.

Regarding turbo: I couldn't verify it yet, but its supposed to turbo just one core. The question is just, what happens to the other core during that time.
Edit: The second core is supposed to be powergated (switched off), while having Turbo on one core. At least, this is what AnandTech guys found, but this info is not from AMD.

-witteks

 

It's a 1GHz dual-core processor for crying out loud...even the Samsung Galaxy S II has more processing power..and turbo boost to 1x1.3GHz from 2x1GHz is just pointless...the hardware is so underpowered that any attempts to make it faster is useless..

My 6 year old compaq which is a P4 runs at 1.4GHz...this laptop is much faster than that. So turbo core is just a gimmick unless both cores can speed up or unless its from a quad core to a dual core

 

guys i wish we can unlock fsb on acer....but iam not hoping for big OC that this cpu is capable becasue they hard locked
yes regarding wei scor. i read it on forum about asus nbooks..

 

there are plenty of smart guys commenting in that slick thread, as there are here. the bios on the c60 models seems to have been a rush job and clearly not yet optimized.

 

how 'bout posting here your win7 WEI nums on that old cpq.
my old 3.4ghz p4 cpq with 4gb and a geforce 8400, and posts WEI nums in the 5's. The AO722 I setup for a client has virtually the same numbers, in fact slightly higher on Aero desktop...
things have changed a lot in 6 years.

 

If you compare mobile cpus with netbook ones that's really a sign you don't know much about this domain.

Folks need to take a deep breath and realize that this an APU not just a simple cpu.

 

Ah yes, one of the trolls who wrongly believes clock freq is the end all, be all measurement of processor performance. UGH!

 

my old 8mhz amiga could do more than todays 1ghz procesors ))))

 

Even my Commodore C-64 was faster!

 

Just installing windows again as ive decided my hybrid drive might be a waste so want to compare it to a 5400rpm drive, i recall somehwhere in this huge thread that there was a to a complete driver collection download anyone help me find that?
