330m gt overclocking

hi all
i got a toshiba qosmio f60-111
and i wanted to play some heavy games with higher fps , so i read some overclocking guides and downloaded EVGA precision and overclocked from
475 , 1045 , 700 to 640, 1350 , 830 which the guides on the internet said it was stable and running good for 330m gt , but i got a shock when the driver stopped for a while and the recovered and the gpu temperature didn't go further than 71 , so i tried many times to overclock again and after few minutes of playing again the driver stopped . but now after the driver recovered i saw dots on the screen !

, it was scary ... , when i restarted the laptop the dots were gone from the screen
my questions are :
why wasn't i able to overclock just like the other people with 330m gt ?
is my graphic card damaged now ?
should i take it to Toshiba customer care to fix ?
thank you for your effort!

 

Every card to going to overclock differently, even if it is the same kind of laptop.

Those speeds are too high for your laptop. Bring them down a little and see if it improves.

Did you see the dots on the screen when the card was still overclocked?

If so it's a product of too high clock speeds.

 

It's obvious that you overclocked too high. You can't overclock in the 100s and expect it to work every single time. Try small increments like 10s or 20s and keep going higher until it's unstable then back down several increments for each core/memory/etc.

Not every GPU is manufactured the same; some are more overclockable than others. It's just luck of the draw.

 

thats really disappointing. people overclock 330m to 650/900/1430 stable

so my stable is
605 , 1250 , 800

and is my graphic card is fine ? or when the dots were shown means that its damaged and needs replacement ?

 

Should be fine, you just reached the cards limit.
I doubt it's damaged unless you see artifacts or something that it does now that it didn't do before.
Try updating the graphic drivers and you might see a performance gain without OCing it to those high levels.

 

Every chip is different, the GT240M is based on a similar core, I have two samples, one reaches only around the 640mhz core level, the other goes right up to 715mhz! The memory on the first goes to 950mhz and the second goes to 1023mhz!

 

Get CPU-Z and check your voltage (VDDC), my VAIO F11 is at 0.95V for 3D clocks, I OCed it from 575 core 1265 shader 790 mem to
705/1551/940

I think the reason is that your laptop might have lower voltage for 3D clock (due to manufacture changing it), as a result u are unable to get higher clocks

Also, some chips are binned with better silicon and can clock higher using same voltage.

Not all GPU (and CPU) can OC to the same level

 

Well Nibitor will be supporting the GT240M in their next release so GT240M owners will be able to change the voltage

 

interesting, take alook thats my max vddc.

if this is true then its the vddc , is there anyway to increase it :O ?
btw my max gpu temperature was ~75 , and 75 which is normal when playing so i guess the driver didnt stop because overheat

 

Thats your 2d voltage, see when you started GPU-z it was higher then dropped with the clocks.

Can you dump your bios using gpu-z for me and upload it?

 

yes when start gpu z it is 0.85v, but after few seconds it goes to 0.8v

how can i do that :O ?

 

Right open GPU-Z, press the button ringed in the screenshot:

It will come up with a window asking you where you want to save it.

Save it to your desktop and then either upload it to any web sevice you may use, or go to NVIDIA GeForce GTX 480 470 465 460 ATI Radeon HD 5970 5870 5850 5830 :: MVKTech :: On the Edge of Technology and register for the forums, then upload it there under the nvidia bios section (you can put an attachment when you post or start a new thread).



Also do you see that check box at the bottom of the window you showed (Continue monitoring when in background) check that and then open a 3d application. Close it and look what that max value says again.

 

for some reason i cant dump the bios


Uploaded with ImageShack.us

and i uploaded the log file

 

so what to do the voltage ? , and how to increase it ?

 

You generally can't read the BIOS with GPU-Z on a laptop. I think that would only work for people with MXM cards. There's no way to up the voltage without modding the BIOS.

For most of us laptop users, the GPU BIOS is embedded in the regular system BIOS, and there are tools out there that you can use to extract it. However, I don't know which one you'd use for your Toshiba. Do you know what brand of BIOS you have (Phoenix, Award, AMI, etc)??

 

I don't think it's a good idea to recommend anyone who wants to overclock to extract/modify Vbios and start flashing Vbios, it's not exactly a safe procedure for anyone, bottom line is, if you don't know what you will be doing, you may easily end up bricking your video card.

If you want to overclock, play with software to OC first and get familiar with your GPU gradually, then you may try hardware OC.

 

True, I'd also recommend against it for most people, but if you really want to adjust voltage there is no other option.

 

i think its needed to oc bios , cause 0.85v is so low
and my bios brand is intel i think check this to make sure

now i need some advices for how to oc bios voltage

 

intel doesn't make BIOS's... OP , basically , you'r limited by how much ur card can OC.. try OCing with NVDIA system tools first... start with your max OC , than increase in small steps.. trust me some brands lock your vBIOS... hp does and quite sure toshiba does too so trying to dump vBIOS is not going to work.. only thing you can do is software OC....

 

if some 1 have the guide to flash vbios ? for 330m gt

 

can't u understand? Toshiba's locked your vBIOS so you cannot flash.. software oc is the only thing u can do...

 

if u check http://www.notebookcheck.net/NVIDIA-GeForce-GT-330M.22437.0.html
the original clock are higher than the clocks in my laptop ...
think they lowered voltage and clocks for lower power consume ? right ?

 

yes they most probably have... all you can do sadly is software OC.. download NVDIA system tools 6.06 and do the OC... vBIOS is locked so no flashing... this is what happens when you buy NVDIA... can't say the same for ATI

 

up

Yeah they likely did, its also a good bet they fixed the voltage too.

 

so how can i increase it now ?
i think i need to flash bios but i dont know how

You know abcanw, what you're trying to do is squeeze ~1 to 2 framerates more out of the graphics card, in exchange for severely risking frying it (permanently), especially seeing that your technical expertise in this field isn't too strong.

Reconsider this, it's a whole lot of risk with very little, if any, reward.

 

what is really disappointing is YouTube - COD Black Ops- MAXED OUT- GT 330m(oc)- Samsung R780

while i cant play it well on normal people plays it maxed out

both r 330m gt , so i think it will be rewarding to increase the voltage

and much more than 1 or 2 fps.

and i understand the risks .

if this dont work i wont stay with this laptop anyway :S

 

This is why I avoid Toshiba and Sony notebooks : they underclock the GPUs...

 

Yeah it is annoying but even though I knew it was undervolted it didn't stop me from buying my VAIO and I haven't regretted it. Luckily my 5650 can OC quite well. I do think it's wrong for manufacturers to do this, it's essentially false advertising as they don't warn you about it.

I notice your laptop (abcanw) is undervolted even more than mine which surprises me. Why does samsung need to undervolt so much?

 

well its a toshiba , and i still dont know how to increase the voltage

 

Do also Asus do this?

I've discussed this about 2 years ago btw And still, we're without results. THERE IS NO WAY TO READ BIOS ATM. Atleast not for my Qosmio, again another Toshiba, another limitation...

 

Considering the fact that he has an Asus laptop and Asus is known for gaming hardware, I'd wager no on that one.

 

That is good news I just hope this is true for all models

 

The Vaio Z is the best thing I have ever seen and owned (this is my 5th laptop).

Anyway my 330m is OC'ed to

core: 620
shader: 1364 (linked)
Mem: 820

And is 100% stable in gaming and every day use.

 

Isn't Asus guilty of underclocking as well?

 

Hi

I have a Samsung R780 Hooke Notebook with
Intel i7 620m
NVidia GeForce GT330M
4GB DDR3
640GB HDD

So, ive overclocked the VGA wit MSI AfterBurner. My stock frequency is 575/1265/790

Im running now at 625/1375/860

3DMark06 score and HighStress Test Photos (Prime95 High Temperature Setting + FurMark High Stress Test)

Are these Temperatures/Settings OK? I guess i could go higher with the clocks but im not sure to go higher.

And, is there any Software on the Market where i can OC my i7?

Thanks!

EDIT: Forceware 260.99, Windows 7 Ultimate x64

best regards from germany ^^

 

That seems just ok. I would say 80 is max, but most of the systems can handle tempratures up to 90C as safe. My 9800M GTX had a max temprature of 83C with no overclock with a older driver version. This gives you maybe a picture..

 

How could you get mid 7k with OC?
Even with OC to 675 MHz core, I barely got 6k with this 260.99 driver.

 

I get 6900 in 3dmark06 with 260.99 OC'ed mentioned above.

vaio Z i7

 

There's no way an i7 could boost the performance by that much.

 

hey....

i dont know why its so "high"

stock 575/1265/790

oc'ed 625/1375/860 over 8k points this time (maybe disabled aero?)

I'd categorize that as "broken" score
low-mid 6000 is probably the "default" score for GT 330m. I used to be able to get 6200~6300 before changing to 260.99 (it dropped to 5.8-5.9k after, weird..)

 

hi

what do you mean with "broken"?
is there any other 3d benchmark to compare?

EDIT: look here, but none is my own
http://hwbot.org/rankings/benchmark/3dmark06/rankings?start=0&cores=1&hardwareTypeId=GPU_1678

 

I go into Nividia control panel and device settings click custom and have a stored profile. Then I click apply. When I close the window it asks me if I would like to apply when windows starts and I click onto yes. But when I go right back and pull up the control panel it always shows the factory settings? Does this mean my custom setting is not being applied? Please advise and thank you.

 

You must here click on CTRL + ALT + H and select your profile... Or does not a simple restart apply your new profile? Did you try that?

 

CTRL + ATL + H sure did work. Never knew about this. Thank you Rep +1

 

No problem mate! I've have done a lot of overclocking on my 9800M GTX, well I atleast tried, so quite familiar with nVidia control panel.

 

YES.

Stock GTX260M clocks (550c/1375s/950m) i7-720 =~ 11k 3dm06
Stock Asus G51 clocks (500c/1250s/800m) i7-720 =~ 10k 3dm06

---

I have auto-under & auto-overclock setup with NV Control Panel + system tools. Two profiles and three rules:
* underclock profile: 400/800/400 (25% UC)
* overclock profile: 560/1400/950 (12% OC)

- load underclock profile on startup
- when power saving mode is "performance' for 5 secs [i.e. CPU is being used a lot] switch to the overclock profile
- when power saving mode is 'power saving' for 20 secs [i.e. CPU not being used] switch to the underclock profile

Takes a few mins to set up, and make sure the broken nv control panel sets it properly , but has worked flawlessly for quite a while. Only issue I've found is some in-game menus stop the CPU usage meaning when you un-pause it's still in underclock for a little while and FPS can be a bit choppy until it switches profiles, hence the 5-sec 'step-up' threshhold, you can decrease it further if you want.

Just helps keep my lappy idle a bit cooler while not having to change profiles myself to fire up a game when needs be.
