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

looks like sven is working hard to get the nb voltage adjustments up and running for brazostweaker. and just an update, i'm running 1ghz mode at 0.85v and 800mhz at 0.775v

 

Okay here we go

Original
1GHZ@ 1,18V
800Mhz@ 1,05V

Temps 58C°idle ambient 24C°

Underclocked
1Ghz@ 0,8625v (he wont take 0,85)
500Mhz@ 0,70v

Temp @ idle 48C° ambient 24C°

 

guys please, write also your original values of voltage and temperature in detail..
and also if you posting downclock temperature make 1hour intense gaming and than keep it on idle for 10-15minutes-thats idle temp., and post your ambient temperature also...its useless otherwise

 

my ambient temps are moving around like crazy. im backpacking all over europe right now so my temps are always moving. id love ambient temps in the low 20's but im facing 30+ around here. in 20 degrees ambient i cant get this thing past 82 degrees with maxing the gpu and cpus at 100% for 30 minutes. my original voltages were:
1.1125v at 1ghz
0.9375v at 800mhz
currently at:
0.85v at 1ghz
0.775v at 800mhz
idle temps are 51degrees
max load (gpu and cpus at 100% for 30min+) are 82 degrees

max load is not a realistic sitatuation and I have to do some crazy stuff to maintain that load. at a "realistic max load" like fluctuating between 70 and 100 % on cpus and gpu my temps are about 78 degrees. detailed enough for ya Krishna?

 

btw idle temps are useless for amd chips. every chip is different. its the max temps that matter. amd chips have always had pretty lousy idle temps. from my experience. the cheap chips at least.

 

ok , but ju can measure something from it...one user report vid 1.8 for 1ghz ..crazy, i dont believe those settings can be so up and down and they are not doing it more accurate..
nice downclock..i give it try once again with those pretty low values..
and for example orthos is stressin only cpu!? i think intense game is realistic test now chilli waiting for overclock

Hmm, either you guys have some nice samples or my c-50 is kinda crap. This is in an acer 722 11in.

0.9v@1ghz and 0.8125v@800mhz/0.7125v@500mhz is as low as I can stably go (VID's even one step lower invariably crash within an hour or two). The defaults were 1.2v/1.0v IIRC.

With ambient temps around 25C, idle is high 50s (the fan never shuts off) and maxes in the low 80s. Normal usage (internet browsing, etc.) hovers in the low 60s. When I was testing the max temps, I switched back to 1.2v briefly and it shot up to 90+ within a few seconds.

For a 9w TDP processor, this all seems absurdly hot to me, though admittedly my other notebook that I currently use is a single core ULV celeron with stock idle-max temps between 35-55C.

 

its hot bec. its cpu, gpu, northbridge on 2cm square area and low fan/ high vid...not help it either

 

Well, Both of my P0 and P1 original vid scores are 1.1875. I may have earlier posted 1.8 which of course would be wrong. So, I apologize.

I lowered my VID TO P0 1.000 and P1 down to .900

Odd that both original scores for P0 and P1 are the same. Anyhow, here is my correction.

 

Hi guys!
First of all thanks everybody for all this info about little netbook!!!
I have one and I love it.

Here is one problem I found:
I have win 7 Starter - missed 20$ upgrade deal and don't want to spend more. Installed 4 G of RAM - after all reading decided to do it once and it was on sale.

Then installed RAM unlocking program (modified kernel):
UNAWAVE - 32-bit Windows 7 with full 4 GB or 8 GB RAM support

Everything works fine EXCEPT my SD card slot - when I put SD card in, machine just hangs up, wireless stops working, USB mouse stops working...

Once I reboot it with normal kernel - SD card works properly...

Any thoughts or comments?

Thanks in advance!

 

That's about the same as my 522, I actually have both states at 0.9v. I might be able to get the 800mhz voltage a bit lower, not too much because it started hanging right away. I didn't care to test more for just 0.125v of profit maybe.
Guess we're just unlucky with our speciments (although I'm still very happy with this machine).
Played NFS underground 2 on this yesterday, runs great with everything maxed at 800x600 (no widescreen support), but my temps were 85c when I quit and got back to desktop (so it probably already dropped a few degrees). So for me, even if it becomes available, I wont try overclocking... as it is, undervolted it can barely keep from throttling while gaming it seems.

 

but with custome fan profile you can easyli overclock...i think on 80-100perc fan we can get 1.3-1.5ghz stable..

 

Does the 6-cell battery stick out or is it flush with the bottom?

 

Doesn't the fan blow at 100% yet when you pass 80c then? I mean, if it does, then there's no point in changing it as far as OC'ing goes, because at max energy use it's not going to blow harder... If it actually doesn't blow at 100% when it's over 80c then acer's got a couple of morons working for them

As for the battery, I'm assuming I have the 6 cell battery (I get batterytimes up to 8 hours or so) and it does stick out a bit on the bottom making the netbook stand at a slight angle when you set it down. It doesn't stick out to the back though and it really doesn't bother me.
Here's a pic:
AO522 | Flickr - Photo Sharing!

 

To the chap with the catalyst control centre issue, have you tried reinstalling?

To the person above about the 6 cell battery, yes it sticks out the bottom a little bit.

 

tested my batterytime this night, to verify what windows keeps saying about how long it will last... Opened the previous page of this thread and used a tool to automatically reload it every minute. Had 3 other tabs open in firefox, one of which gmail which also refreshes itself (or at least maintains some connection to the server). Display brightness is at 1 step up from lowest which I find more than enough for indoor work. Booted my system after the battery was full so the uptime in performance tab of the task manager would show me how long it lasted before suspending, and it lasted 7 hours and 25 minutes. Not bad

 

its like my asus ati 5850 has low fan profile( 20-32%+more in overheat area)...i push fan only 5-10 perc. more and i got minus 10 deg. celsius,& iam in safe area ...i suspect they are making this on purpose to burn the hardware quicker...i will bet on it ))) and btw. i read somewhere that fan is off to near 55 deg. celsius on acer

and imagine you oc if possible, vid to 1.2-1.35 pushing to 1.3-1.5ghz(best trough FSB increase) and set fan to 80-100%, maybe more than 1/3 or near half of speed increase

 

Mine too. It´s about 60 °C when idle or browsing or writing in word, 75 °C when watching DXVA videos or youtube videos, but it goes over 90°C when watching live streams. Undervolting helps a little bit, it doesn´t go over 90 then.

yes, I tried it and with low settings it´s definitely playable

 

Thats pretty strange. I ran prime small fft plus a 720p movie at the same time and never got passed 75.

 

I think it´s a drivers issue. Except for youtube no internet videos are gpu accelerated thus the temperatures go high (for me at least)

 

Guys, I'm gonna getting New Vegas, do you think it's gonna run decently?

 

That may well be true but prime95 runs both cores at 100%. How is it possible that a website would utilize more cpu resources?

I think its a reporting error. Try coretemp instead of hwmonitor.

 

I'm just wondering, but, how sure are we that coretemp actually reports the correct temperatures? I'm wondering because, when I've left my netbook on standby for a few hours and can reasonably be sure that the netbook has completely cooled off to around ambient temp (which is about 22c) and wake it up again, it immediately shows the temp as 45c. It then very slowly inches its way up to 50, 55 after the CPU actually had to do some work. If it actually burned its way up to 45 from around 25 in the 4 or 5 seconds it takes to get to the desktop from standby, it would continue to go up faster (I'm guessing a bit but it's probably 10-20 seconds to even get off 45). It also doesn't make sense if the cpu actually uses so much power in standby that it stays at 45c since it barely uses power in standby (I've had this netbook last for a week before having to charge, taking it out of standby for 5 to 10 minutes at a time several times a day while studying)...
So, could coretemp actually be wrong? If so, maybe the cpu actually doesn't get that hot when stressed either? Although now as I'm typing this I do remember someone had some pretty convincing evidence of the cpu throttling at 90c... so I'm not sure.

Oh and... @adhiofawkes, you already asked that, you might at least read the posts since then to see if someone already answered you, it's only 2 pages or so...

 

fan is probably off till 55 deg celsius..that can explain it and i read it somewhere

 

Is anyone here, who can get me some feedback on BrazosTweaker V.1.0.3? I've heard, that making the voltage changes permanent isn't properly working due to not using the P2 PState.
I do believe, I've got a solution for it, but don't want to release it without having some feedback from beta testers.

You have to know, that I don't have a C-50 APU for testing. I own a netbook with an E-350, which uses P0/P1/P2.

Regards,
witteks

 

Well I wouldn't mind testing it, but I don't have that problem... I set the voltage changes with the service and it works brilliantly.
Thanks for your work btw it makes using this netbook even better of an experience than it already is standard.

 

hi

Here is your mod

Remember, my mod is just modifying the setup offset. By clearing your CMOS or deafaulting your BIOS setting will reset the mod.
A permanent a solution is to modify your setup utitilty which I still have no idea.

WARNING. MODDED BIOS. FLASH IT AT YOUR OWN RISK. LAPTOP BRICKED ISN'T MY FAULT.

@Sven
Brazos Tweaker Voltage-Mod works perfect. Iam using only P0andP1.
No problems it is working permanent!

@SD3120384
Did your Modbios unlock the advanced menu?

 

@derdahinten
Yes, but I did not open the hidden menu, for unknown reasons ... are concerned about the `` `

 

Witteks,

Is this the level of detail you want to see?

On my AO522 I've used BrazosTweaker 1.0.3 to change P0 VID to 0.9000 and P1 VID to 0.8000. I do not touch P2 settings (except see below). I've then used "Service - Make custom P-state settings permanent" per the User Guide. The BrazosTweaker service is installed and functions. During tuning of VID, when the machine freezes, a re-boot returns to the customized permanent settings.

System Event Log shows the kernel mode driver WinRing0.sys and the BrazosTweaker service loading without error.

Attempts to change NB P0 VID bring up the error window "Invalid P-state settings", "P2's VID is greater than P1's." Attempts to change P2 VID cause BrazosTweaker to crash with the message "Unhandled exception has occurred in your application........Load a P-state first for safe initialization."

No corresponding event log entries are made for the above BrazosTweaker 1.0.3 crash.

Thank you for BrazosTweaker and your work!

Regards,
Harry

 

@witteks

I've been using BrazosTweaker for nearly 3 weeks now and the CPU part works fine for me.
As I have a C-50, only P1 and P0 states work off course and I could set P1 to 400Mhz @0.6750v and P0 to 1Ghz @0,8750v.
The service feature works like a charm and my settings are set correctly after a reboot or after coming back from hibernation.

The only bugging part is the NB P-States.
I can modify the NB VID, but to avoid the "P2 error" I need to set P0 & P1 VIDs to 1v (or any value >P2's VID), then decrease NB P0 and NB P1 VIDs and then reset P0 & P1 VIDs back to their value.
The problem is not only the "P2 error", but after a reboot or coming back from hibernation, all NB VIDs are set back to their original value.
Also the Service feature doesn't save NB VIDs and the Multiplier and FSB values can never be modified.

It'd be great if you could solve the service feature for the NB VIDs value or if you could provide a trick to avoid values from being reverted back after a reboot or hibnernation.

I don't know if it's interesting for you but we could send you screenshots of the values displayed in the status tab for the C-50.

 

hi, so what the moded bios can do ?
and why hidden menus are not working?
your link to file is not working for me... ?
thanks

 

@krishna
I do not know why not work, this is to unlock the advanced menu, if you like me are interested, please join me and concerns, that link can not be estimated to be server crashes, the attachment is to modify the BIOS, renamed rar and then extract

The real reason 32 bit windows doesn't support > 2G ram is that many 32 bit device drivers are not PAE aware, and try to write data to the wrong address, often crashing the machine. It's likely that the driver for your SD card reader is one of those drivers that isn't PAE aware. Note that 32 bit versions of Windows Servers can use > 2G ram, but many device drivers are blacklisted because of this issue.

 

Hi sd3120384,
thanks i got the file!, but please write some info and details what bios version it is and what and how you change it, you are saying that it should open hidden menus but its not working on your a522 nbook ? and you are saying CONCERNs but it means something like "BE AFRAID"...tell us more please

 

@krishna
Now the latest to open some of the hidden options, but still not advanced menu, look here want to know the progress
http://forum.notebookreview.com/acer/599633-insyde-h20-bios-setup-utility-extracted-3.html

 

i read the progress, i see your concerns now ) i have no ball to test experiment tell us what is inside hidden menus? it seems more work to proper crack it

 

Here some Pics of these first "hidden" things.

 

i see nice, but will advance menu help for overclock or hardcode bios unlock is needed?
upd: what i see on different acers, bios adv menu should have all CPU , gpu,fan, ram, etc. settings so please crack it

 

Wow so the possibility lingers

Hope for OC.

 

Modify the advanced menu to find Netroller3d, who know this man?

 

He is from this Forum!

Ill send him already a PM to help us.

Yesterday he was here active ---> http://forum.notebookreview.com/ace...deocard-now-always-shuts-down-after-boot.html

 

Could I ask you 522 experts something? this is I'm sure a mundane issue, and concerns the 722 model but I see no good threads rolling on that one.
A few users of 722 report lousy performance on HD content: playback of 1080P sources is not good - stuttering, halting, etc.
Beyond the routine measures of getting rid of bloatware and bad anti-virus/malware programs, reloading drivers, etc.... if all that fails to clear the issue, what's the final solution? wipe and reload OS from scratch? and download/install the GPU control app?

Edit: to clarify: we're talking about exporting via HDMI to a big screen...

 

You may want to try, if you see a difference between being plugged in vs running on battery (both in High Performance plan).
There is a PowerPlay setting (under advanced power options), which keeps the GPU from stepping into the faster mode sometimes.

But first check, if you see a difference.

-witteks

 

Thanks! I appreciate it!!!!!!

 

ok. can give that a try

 

download "system monitor" software from amd's website and make sure the gpu is being utilized. if you see more than 70-80% usage on cpu and low usage (<5% usage) on gpu, then your not really taking advantage of the great embedded gpu on the apu chipset. install the mp4 and wmv codecs for amd apu from the newest amd CCC package from amd. i like windows media player because its very low resource, but mpc-hc is a good alternative if you want full control over your media files. you will know if your gpu is being utilized in mpc-hc if you see DVXA acceleration on the status bar while running a video. you should get stutter free 1080p performance. I only have issues running 1080p 60fps video files, but those are a rarity. 1080p 30fps, 720p 60fps, and anything under works perfectly with now stuttering or dropped frames. good luck! get your hands dirty and get the most from this bargain of a computer.
