AMD Radeon 6630M? Overclockable?

i see, the problem is i have bought 3DMark06 already. is 3DMark Vantage free?
i'm just a bit reluctant to install too many unnecessary software on the laptop. do you really think i will get a better benchmark result comparing the OC'd to the stock settings if i use 3DMark Vantage rather than 3DMark06?

 

They're all free. 3DMark06 is free, only pay to modify settings and view your results locally. Vantage is a bit of a PITA though because they give you one run for free, then you have to register for another run. 3DMark11 is totally free too, but you can buy the pro version to manage more stuff too.

In any case, 3DMark06 tests DirectX 9, 3DMark Vantage DirectX 10, and 3DMark11 DirectX 11.

I'm just saying that DirectX 9 drivers are far from optimized. I guess it'll give you a decent ballpark on the performance improvement, but only for DirectX 9 games.

In any case I've found 3DMark somewhat unreliable in many cases. I get marginal improvements in the benchmark, but excellent in-game. Your best bet is to test the games you play before and after and see if it makes any marked improvement.

 

so i tried another overclock setting. the old settings were 650/950 for GPU/memory clocks. this time, i increased the core clock to 725MHz while decreasing the memory clock to 900MHz (which are the stock clocks of 6730m). running FIFA 12 or 3DMark06 would lock up the machine with stock voltages, so i increased the voltage from 0.900 to 0.905 (that is from 900 to 905 in TRiXX). then 3DMark06 ran fine without lockups or artifacts, and the new score is 9130 (with SM2.0 score of 3275 and HDR/SM3.0 score of 4086); the difference is 111 points in favor of the new settings.

the temperatures were about 1C higher on average than the old ones (on average, around 75C), with maximums occasionally reaching 82C. i have yet to try FIFA 12 on the new settings; the temperatures there is what is important for me.

so what do you think? is memory the bottleneck of this GPU, so a memory clock of 950MHz is better even if the core has to run 75MHz slower? or you suggest i go back to the old settings and increase the memory clock?

EDIT: so i played FIFA 12 while the GPU was overclocked to 725/900 with core voltage set to 0.905. there were no artifacts or lock-ups, but the GPU was running about 2C to 3C hotter (i.e., 77C-78C) than when it was overclocked to 655/950 with stock voltage (74-75C). i guess for FIFA 12, i'll keep the old OC values, and if i decide to do more serious gaming (e.g., BF3) on this laptop, i'll then clock it higher.

 

how did you underclock your CPU? which program did you use?

 

no ideas on memory vs core clocks? i'm referring to two post above.

 

hi!...i can't overclock radeon 6630, none program show me radeon clocks



help me?

 

You probably have the Dynamic Switchable. The GPU is completely powered off when not in use.

EDIT: except for the PCIe bus.

 

Hi all;
@liam19 try click RMB on desktop-> Graphics properties (Catalyst)->power managment->Switching method -> Set manual and chose option high performance
Then use sapphire trixx

@darxide_sorcerer, try increse memory clock

My results for Lenovo E420 1141EAG (NZ1EAPB) Corei5 2430m; Ati 6630m 2GB;1x4GB RAM
GPU 690MHz, Memory 1125MHz works perfectly fine (for GPU 700MHz and memory above 1000MHz it crashes dx driver; for GPU 690MHz and memory 1150MHz there are some artifacts)
Benchmarks results:
3DMark06: 9034

3DMark11 1356 Points; Graphic score 1225
Temps 3DMark06 CPU 78-80C, GPU 62-66C
Temps Furmark CPU 82C, GPU 78C
Temperatures above are with cooling pad (xigmatec), without it in Furmark CPU breaks 88C and GPU is couple degrees above 80C

I'll try BF3 tomorow

 

You are EXCELENT!!!!...

Core @650
Memory @960

temp in gaming (cod 4) @ 65degrees


test more?

 

yeah, i have since increased the memory clock by 50MHz and currently run 725MHz GPU + 950MHz memory + 0.905V core voltage. my 3DMark06 score is 9353, and the maximum temperature while playing FIFA 12 for a couple of hours is 79C without any cooling pad. maybe i can break the 1GHz limit with the current core voltage, but i'll leave that for when i decide to play BF3 on this laptop
please let us know about your BF3 experience on the OC'd 6630m...

 

which is the maximum temperature supported?

 

there is no maximum supported temperature. overclocking is not supported, period. as far as i know, anything below 85C is considered safe...and the lower, the better!

 

shortens the useful life of the laptop?

 

BF3 Single 1440x900 all medium no AA, anizo 2x, OC Core 675 Memory 1100; from 24 to 30-40fps, mostly about 27, never below 23. Temp CPU 88-90C , GPU 75C.
For 1920x1080 and OC with similar setting is 16-22 fps.
When Core was OC to 690 it was stable in benchmarks, but in BF3 game run for about 5 min and then closed to desktop
I'll get second 4GB memory module in this week to run memory in dual channel and maybe replace thermal compound to noctua NT-H1.

 

core 975? wow! did you have to overvolt the GPU to achieve that high of a clock? that's a pretty insane overclock...i'm impressed.

 

My mistake, 675

 

Memory can be increased more than the core? in my case core 650 memory 960

the gpu is only shown at 650MHz only when running games? runs windows in low frequency??

 

my best overclock is 650 core 1060 memory at 65℃, in 700 core the pc is crashing

 

my overlock: core 745, memory clock 1230

 

As long as it's not (a) throttling or (b) a defective nVidia board, don't worry about the temps too much, your GPU will be obsolete before it dies.

As long as you don't go over 90-95 on a regular basis you should be completely fine.

 

what's the core voltage?

 

My Record only until 750/1125/965 From 485/800/900. I have the videos of amd hd 6630m overclock. just check it on there. or, i will give link instead

xxx/xxx/xxx= Core clock/Memory Clock/GPU Voltage

 

Nevermind..

 

@vioz_87: aren't you pushing the GPU too hard by overvolting it by 65mV? what are the temperatures you're getting?

my 6630m is stable at 725MHz/945MHz/903mV (mine is just an overvolt of 3mV), and it gives me great performance in Battlefield 3, where the average temperatures are around 85C with the maximum occasionally reaching 91C (but not staying there). i'm not going to push it harder, since SA is smaller than SE/CA/CB and will have a hard time cooling itself down.

 

On my SE I have it at 721/1075/903 with 9303 in 3dmark06. Temps don't get over 70C.

 

^ damn those big laptops! your temperatures are really good...

 

another overclock for VAIO SA: 725MHz core/975MHz memory/0.908V voltage (that is up from the previous settings of 725/945/904). i am now using the CoolerMaster NotePal U2 cooling pad (with movable fans which i have placed right under the notebook air intakes), and it is working wonders for the GPU temperatures. before this cooling pad, less than 5 minutes of FurMark would increase the GPU temperatures beyond the threshold (95C or 100C maybe?), and the notebook would shut down. with the cooling pad, 10 minutes of FurMark was completely stable with maximum temperature of 89.5C.

the new 3DMark06 score is 9512 (SM2.0: 3396, HDR/SM3.0: 4276, CPU: 3638); that about 25% increase over the stock settings of 485/800/900.

 

After reading this thread, I have started overclocking the 6630m on the 15.5" SE. I'm running 725/1075/903 on Trixx. I got max of 70C (on Silent Mode, but on Speed Mode to use GPU) on my racing game.

However, I don't know why 3dmark06 runs very slow on CPU benchmark. It's a ridiculous slideshow (0-1 FPS). GPU benchmark did not crash on those settings though. Why is mine doing that on the CPU benchmark?

 

^ mine does that too on the CPU benchmark, jumps between 0 and 1 fps! but i don't think the CPU benchmark is important a anyway. what is your 3DMark06 score?
btw, you're lucky you can OC your memory clock above 1GHz with such a low voltage. you must have gotten a pretty good quality chip.

 

How long did you wait when you are at the CPU benchmark? I didn't want to wait and ended it, so I don't know what my 3dMark06 score is yet.

I haven't tested the settings enough, so might need a little more voltage.

 

the whole benchmark takes about 10 to 12 minutes. the CPU part ends in about a minute if i remember correctly.

 

I got my 3DMark06 score here:
AMD Radeon HD 6750M video card benchmark result - Intel Core i5-2430M Processor,Sony Corporation VAIO score: 7719 3DMarks

During the benchmark, there were some odd yellow spots (likely artifacts) that were shown sometimes. Time to up the voltage.

The program thought the 6630m was the 6750m (well they are essentially the same chip anyway). Maximum of 69 Celsius.

How did you get higher 3DMarks? My settings are nearly the same (725/1075/904), but with artifacts.

 

Yep, pretty much same chip, minus clocks.

 

Not true. The 6630m has DDR3 memory while the 6750M has the much faster GDDR5 memory, this alone improves performance bij 25-30%.

 

this is weird. i think there's something wrong with your setup (maybe the drivers?) with your clocks, you should be getting a 3DMark06 score close to 10k. (my 725/975/908 settings get a score of 9512.) and yes, if you see artifacts, your OC is not stable. increase your core voltage a bit more and run it again, and watch the temperatures.

EDIT: your CPU score is very low compared to mine. are you checking its temperatures as well? it might be getting too hot and throttling down (are you running in Silent Mode profile?)

 

Yes, I am running on Silent Mode, that's why the CPU is throttled (at 1.5Ghz instead of 2.4Ghz in the link), thus score is lower. But I want to keep the temperatures low during the benchmark. If I change the VAIO control centre to performance mode profile, I will probably get 80c for the CPU during the benchmark, not really a good idea for CPU life.

Drivers shouldn't be a problem, I haven't touched it at all. (I updated to the newest drivers from Sony before, but that added the Catalyst Control Centre, so I reverted it).

Maybe the memory clocks are a little high (and require a lot of voltage, so I'll try your settings when I'll get to it later).

 

Meh, your CPU will die in 15 years instead of 17, life could be worse.

 

^ +1 above! besides, SE's cooling is more efficient than that of SA, so i don't think you need to worry about the CPU getting to 80C. even if it does, it's still in the safe zone.

 

Just finished the benchmark with your settings except 903 voltage (I thought the 8 was a 3, haha), I got much less artifacts now, time to bump the voltage up to 908. Guess you are wrong about my chip being a "golden one", the voltage increase for the previous extra memory overclock (1075) isn't really worth it even though it still runs with artifacts and no crash.

Here's the new score on Performance Mode (it's still lower than your score for no reason): AMD Radeon HD 6750M video card benchmark result - Intel Core i5-2430M Processor,Sony Corporation VAIO score: 8828 3DMarks

Max of 88 Celsius (especially gets hot during CPU tests), that is way too uncomfortable for me unless if I have spare cash for a notebook cooler. Intel recommends staying below 72C, if I recall correctly.

And no, the cooling is likely identical to the other 13" S Series. The fan is rather pathetic (it's only a few millimetres thin I believe, and here's a link for the photo: http://forum.notebookreview.com/son...se-owners-thread-post8111368.html#post8111368)

 

No, it's the same core, just different video RAM. Sorry, I should have clarified, I meant chip as in the actual core.

 

my SA is not stable at all with 725MHz core/975MHz memory unless i bump the voltage up to 908mV. besides, i don't even game on those settings, but use 725/945/904 for less stress on the GPU and less heat. the extra 2 or 3 frames per second is not worth it for me. i just tried those clocks to see how far i can push the chip.

i totally understand your reservation. that's why i got a cooling pad for my SA for when i'm playing Battlefield 3.

there is more space in the SE's chassis for the air to move compared to SA. i think SE's fan is also bigger a bit ( this is SA's).

 

Final test with your "good enough" settings (725/945/904) on Performance Mode: no artifacts (if you don't consider one entire yellow screen flash for very quick moment, maybe some milliseconds during the serpent and flying boat benchmark).

Benchmark score here (still can't get into the 9000s, I'm stuck in 8000s range): AMD Radeon HD 6750M video card benchmark result - Intel Core i5-2430M Processor,Sony Corporation VAIO score: 8663 3DMarks

I'll stick with this setting, it's only about 0.5-1 FPS lower than the 725/975 setting for the benchmark, but 4C cooler (84C load, still very hot though).

A little off-topic, but now I am interested in undervolting the CPU (for cooler temperatures). Any good software for that purpose?

 

afaik, you cannot undervolt the Core i CPUs. you could with the previous Core architecture (Core 2 Duo, e.g.), but not with the newer ones.

 

Why is it not possible to undervolt the (1st and 2nd gen) Core i series CPUs? Because there is no software support for newer generation tech?

Again, sorry for going off topic, as undervolting is also relevant in CPUs (and GPUs) as well.

 

i'm definitely not an expert on the subject, but i've been told by the experts at NBR that Intel has apparently disabled (or removed?) that functionality for the end-user. sorry! i don't know anything more about this issue.

 

Hello - thanks to everyone for the excellent thread. I had no idea there was so much headroom in a 6630M.

I picked up a Sony Vaio SA model with a 6630M. While I can use Trixx to adjust core/memory clocks on the GPU, I don't seem to be able to adjust voltage; that field is blank.

Any tips on how to adjust GPU voltage?

 

See my overclock guide, specific to DV6z but still applicable.

http://forum.notebookreview.com/hp-...overclock-optimization-guide.html#post8247084

 

you have to use Catalyst 11.9 or earlier drivers. apparently, AMD has disabled the ability to change the core voltage in 11.10+ drives.

 

is there a way to undevolt the 6630m in a dell vostro 3550?
in trixx i can only raise the voltage, and in msi afterburner i cant change any voltages, too?

 

I tried to overclock my 6630m on my vaio sa. The overclocking part is very simple, but I cannot get the card to reset to original clock in TriXX. Everytime i press reset the program force close itself. Can someone give me some suggestions?
