Official Llano overclock/undervolt result

What temperatures are you guys running under load with your overclocks? What's a bad level to have them at? I've been trying to keep mine under 80c.

I have it set up to keep around 75c during long modern warfare sessions....

I see some 3ghz overclocks out there.....how hot does it run at this speed?

 

3GHz is damn impossible to achieve for most users. I can get 2.9, but temperatures can exceed 90C and some internal thermal throttling can also go on. I see diminishing returns beyond 2.4GHz because temperatures and internal thermal throttling.

At 2.4GHz I can keep all games, including BFBC2 and BF3 which tax the system the most, at under 75C. I find 2.4GHz the "sweet spot" for performance and temperature, at least with my system and A8-3510MX.

For benchmark purposes I've run at 2.933GHz, and it does fine for short periods, but for actual gaming, forget it.

 

Thanks for posting your config. I am using it myself now.

 

Everyone needs to be careful with these profiles. Don't be surprised if your machine locks up or BSOD's. Every machine and chip is different and needs to be tuned accordingly.

 

Does anyone have stable setting for Undervolt/Overclock for the A8-3500M for an HP dv6 laptop?

Thanks

 

You will have to tune all the P-states yourself. Every cpu is different. You are certain to get instability if you just copy someone else's profile.

 

I agree play and tune yourself I have only got one profile to work weeks on end and that was my own tweakin

 

I registered just because this thread is awesome. I bought a Gateway NV55S09u and I love it. I got it because I wanted a laptop with great battery life and still be powerful. After some tweaking with k10stat, I managed to get my power consumption down to roughly 6.5W for just note taking (wifi off, no usb devices on, lowest brightness), and 9-11W browsing the web/watching videos/listening to music. I can get roughly 4.5-5 hours of battery life just listening to music and browsing the web

Relevant specs:
CPU: AMD A6-3400M (1.4/2.3GHz, Radeon 6520G)
HDD: 500GB 5400RPM WD
RAM: 2x2GB DDR3 1333 MHz
6-Cell 48 WHr battery
No Bluetooth
DVD/CD-RW drive


Got it for $430. It was $380, but they bumped the price up they day before I ordered it. Oh well, still cheap for what this thing can do.

I love this thing, but I have the feeling I should have waited for trinity, but I was overdue for a new computer anyway.

Here's my current k10stat config:


It's pretty stable (for me) -- been using it for a few days without problems. Use at your own risk though. As others have said, not every system is the same. I haven't ran any stress tests yet, but I haven't run into any problems.

As I was tweaking, I noticed that I couldn't get any significant reduction in power consumption by lowering my voltage more than .7125V. For example, at .65V (500MHz) my system draws just as much power as .7V (600MHz). But I DO notice a significant decrease from stock voltages/clocks, about 3W less for just web browsing. So could this mean that there is some hidden lock on the range of voltages that k10stat can set for this CPU or something?

Here are some graphs to show my power consumption. The first is at the settings shown above. I have chrome open with 6 tabs, one of them is music, I have an IRC client open, paint, and some other small things. I'm using power saver as my power plan, screen is at lowest brightness setting (which is still pretty bright!), no USB devices, headphones are plugged in.:


Stock settings:


Power consumption at stock (measured at similar conditions as the other graph):


The graphs were from HWiNFO

I may try to overclock it later on, but right now I have no need to. Plus, I'll get some good thermal paste and maybe a better fan or a cooling pad.

 

If Trinity ends up being all it's cracked up to be, I'll probably end up going with one of those machines to hold me over for a couple years. My gaming time is lessening, and been using my desktop more and more.

In any case, the Llano is actually an excellent budget machine with great performance and battery life especially with K10stat. I'm so glad AMD left it unlocked.

 

Amazing thread and info! And much appreciated. Decided to try this out after the FPS drops in Skyrim using only the A8-3500M. 2.4 @ 1.075V. Peaks at 64C after a few minutes of gaming.

 

Not sure if anyone else has experience this, but recently on k10stat and cpuz it has been showing my cpu stuck at P0, it won't drop to P6 even when I don't have any programs running. When I first setup my K10stat overclock profile it would go through the normal progressions depending on workload, now it's stuck running at 2.4ghz 24/7.

 

First go into Windows Task Manager (Press Ctrl-Shift-Esc), Processes tab, and click to show processes from all users. Sort processes by CPU (just click CPU), and see if there is anything taxing the CPU a decent amount. On system idle it should be pretty much 99-100 going to "System Idle Process".

Otherwise, go into k10stat and make sure you don't have all the P0 state buttons locked. They should be set to auto.

Here's what I mean:

P0 locked:


Set to auto:

 

Definitely pretty beast. At the same clock speed and voltage mine hits 10-15C higher than that when stressing both the CPU and GPU. Even just using the integrated graphics I get about 5C higher

 

Nothing is locked, system going idle, you can see the cores are not being loaded much, yet it stays at p0. I even tried to put the up% to 80 to see if it would stay at a lower state longer when under light loads. It starts at p0 and stays there.

 

It is funny that some guys use IntelBurnTest to test stability on an AMD cpu.

I am kidding. I am just envy of you that you can oc your processor so easily while it is impossible for me to even stop my 2630QM going to lower turbo P-states.

I would go for a liano but there is completely no support on the OS I am using (it is forbidden to talk on this forum about that OS for non Apple machines so I do not name it)

Continue the good work. +rep for everybody OC

 

Just ordered another 4gb stick of kingston for my Dv6-6117dx, the best buy black friday one. It's really nice that they only used 1x 4gb stick in it, would of been pissed if they had 2x sticks of 2gb. Really impressed with how cool it stays even when running at 2.4ghz. I rarely go between 70-75C. Even when playing my game of choice, Knights Online...ya I like free to play games . I have not noticed the noisy DVD-RW drive that others complained about, mine is totally silent.

 

I managed to open my laptop an NV55S03u and replace the A4-3300M with an A8-3500M, but when I ran Prime95 I'd get temps of 85C or so, way to high especially since the GPU wasn't even running 100% load. I decided to try undervolting and I got it to actually lower from 1.4125 to 0.9000 and remain stable for hours. Anything lower results in rounding errors.

The max temp with that was 60C while using the 6620G 100% load with Furmark + Prime95 results in around 75C. An amazing change!

I'm just glad K10stat works, otherwise I'd have a little problem with heat.

Actually I reapplied thermal paste 3x not much change in temp, thank god this worked. I just wanted the 6620G

 

WOW 1.4125 stock volt? On my A8-3500m from HP the stock volt for 1500 is 1.0750, and 2.4 is 1.3375. I wonder if it was keeping the same voltage as it had with the A4.

 

Ok found out what the issue was. In AMD Vision Engine Control Center, under performance/CPU POWER. On the Plugged in Bar, the minimum was set all the way up with the max, listed at 1500, but since I had overclocked it with k10 it was stuck at 2400 p0. Once i dragged the Min all the way down it now progresses through states normally.

 

I turn off all that PowerPlay crap. Use windows built-in throttling or K10stat.

 

Hey HT I know in the other owners lounge most of you have the 6750 card. I just have the 6620G, with the 11.12 AMD Vision Engine Control Center. I don't think it has as many options under gaming as you'd get with CCC. I downloaded the auto detect/installer from AMD's site. Do you know if anyone has tweaked any settings to get better performance out of the 6620G alone? Since I don't have crossfire or anything else.

 

Oh it has
SmoothVision HD: Anti-Aliasing
SmoothVision HD: Anisotropic Filtering
Tessellation
Catalyst A.I.
Mipmap Detail Level
Wait for vertical refresh
Anti-Aliasing Mode

Those are the only things I have to tweak.

 

Great thread guys thanks. I see some comments about not copying other peoples profiles so I have chosen to undertake this myself but could use a few pointers on the best way to do this please.

My plan is set all my frequencies before hand and leave the voltages at stock. Then lock each p state individually and find each ones lowest stable voltage using Intel burn test for quickness then prime 95 to be thorough. While checking the temps of course. Will it be ok to stress test the lower p states on their own?

As for the turbo state I assume that this is better tested with no state locked in.

Any help on the most efficient way to do this would be appreciated. I can find videos of people who want you to copy their profile but no advice on how to do it yourself.

 

Only thing I can suggest is put all the features to "performance" under the gaming section of the control panel, except leave Smoothvision alone.

 

That didn't get me to where I'd like to be...

 

I copied other profiles to get an idea baseline on what is possible.. I have a folder saved of people's k10stat settings that I use for reference, and just go from there. Typically I won't run as low a voltage that I see others run, I will keep it just a little higher to test, than go from there. Of course though I have cut holes on the bottom of my case so it has a little better cooling than stock which helps.

 

Thanks for your reply. I do however draw the line at putting hole in my laptop

I found this guide on k10stat which is great
Aspire Gemstone: K10STAT AMD Griffin Processor UnderVolting Guide

I didn't know that you could lock the p states using enable clock control so that has made the job easy. The writer suggests going up a few notches in voltage from the minimum you find as a safe buffer. Not too low voltages like you say. If I have some temperature to play with I'd prefer stability like yourself.

Thanks again

 

You don't need to enable clock control to lock the p-states. They will enable as soon as you hit apply. Also, I agree entirely about the voltages. I tested to stability and raised it up an additional notch for each p-state.

 

I tried searching this thread, nothing came up. I tried A6-3420M, 3420M, 3420, nada. So, here's my post. Does anyone have reliable settings for this particular APU?

Thanks.

 

You will need to test them for your specific machine because every machine and CPU is different. What works for one, doesn't work for someone else. Check out my K10stat overclock guide here: http://forum.notebookreview.com/hp-...overclock-optimization-guide.html#post8247083

 

... Got a lot of work ahead of me, I see.

Thank you very much for this.

 

No problem. Unfortunately it is a bit of work, but once you tune it in, it's great. There's been people that borrowed someone else's profile with success, but you can also get lockups. Wish it were as easy as copy / paste.

 

I bluescreened and locked up a couple of times, but I found stable temps and voltages.

I definitely need to max out the 8 GBs of RAM in this thing, but I can still play L4D 1 & 2 at 720p (1366x768) and high settings without much of a FPS drop.

Dang impressive machine.

Here's my specs for K10stat:

B0: 2500, 1.1375
P0: 2467, 1.1250
P1: 2400, 1.1125
P2: 2350, 1.1000
P3: 2333, 1.0875
P4: 2267, 1.0750
P5: 2250, 1.0625
P6: 2200, 1.0500

Temps range from 49-88c, depending on load and where I lock K10stat to. I played L4D on 2200 and the temps never went above 60. I wonder if I could undervolt it even more?

I read the part about unganged and such, but I have to admit, it's over my head. How does that work? Or should I just leave it be?

 

i was having lots of success with k10stat oc of 2700 on P0. I had a few blue screens as part of the testing. After the last blue screen, regardless of what I do, I am stuck at 800mhz, whether k10stat is turned on or off. I have tried to modify my power profiles, it is not doing anything. Can anyone help, i have been working on this all day.

 

Make sure K10stat is set to control clocks (right click K10stat in tray). Then open K10stat, deselect then reselect the "boost" checkbox then click apply. See if that works.

 

my optimiced overclock/underclock in A6-3400m + 6650(asus k53ta)

 

Hey, im new in "overclocking" and i hope you can help me.
First, sorry for my bad english.

I have a A6-3420m CPU and tried this setting for overclocking :

To get this overclock, I used k10stat to manipulate some settings. I proceeded this by setting a DID of 2 (Divider which breaks down each multiplier step in 50MHz increments), and a FID (multipler) of 31. This has to be done for every P-state to ensure your clockspeed won’t jump around (unless of course you only feel like changing your turbo boost p-state). I changed my voltage to 1.1125Vcore. I monitored my CPU speed in CPU-Z to confirm my changes.

But i got a Bluescreen after using the "run" function.

Can someone help me, to improve my perfomance?

 

I'm surprised no one in this entire thread uses or has used FusionTweaker. In my opinion it is far simpler & easier to use compared to K10STAT. If you haven't tried it, give it a shot. I prefer it for its simplicity & it accomplishes the exact same thing. Unless there's something I'm missing, someone please correct me.

Is it possible to underclock too much? What would be the symptoms/results of such?

 

FusionTweaker does the same thing as K10Stat but doesn't have individual profiles. I guess it would be a good start and then once you get settings you want just use them in K10Stat. FusionTweaker also will set the settings on startup so you don't have to run it in the background like you do with K10Stat. I guess whatever your preference, both are great programs, but both require tuning of your machinen for optimal results.

Underclocking too much would just result in freezing or hangs.
