    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.

    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
    3DMark Vantage P5110; GPU score 4490; CPU score 8671; JN 13,5 fps; NC 12,9 fps; Ai 1189
    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...
