Laptop GPU overclocking isn't so outlandish once you try it.

wow i expected a bigger jump (like around 150 points) when you overclocked 100mhz on the core. 80-90 points with a +100 core something is wrong -.-

 

I dl'd the Riva utility just today...I'm now OC'ing!! hehe, WoW seemed to load a bit quicker, I only did a 20mhz jump though...(450 -> 470). Plan on playing it safe for now. Also, has anyone had a chance to experiment with increasing the memory speed (mines set at 700 effective)?

 

Well I got mine core clock up to 500 mhz, and it is pretty smooth. Everything is going well so far. And Mobius, so you can finally run DX9 in Cod2? At what settings, Im thinking of trying it right now.

 

nobody knows about memory overclocking?

 

Well, I have gotten my memory up to 900 Mhz, but it did not do that much of a difference. Just about 30-40 3DMarks05. The core is what really matters. I got my core up to 700 Mhz, but after about 15 minutes it started artifacting.

 

You should know that that card doesnt have real memory according to Nvidia.com. So therefore it shares it all. That means that overclocking the memory wont net a large increase in performance.

However, on a normal video card, memory overclocking is what leads to the largest performance increase.

 

hmm alright guess i'll stick to core clocking for now..thanks

 

in lower end cards overclocking the memory does not make a huge difference. unless you have GDDR3 or GDDR4 i don't see the point.

 

Oh really, It says that it has 32 MB of dedicated memory. So it doesn't really have any memory. That sucks.

 

hmm, i believe that the 7200 has 64 dedicated?

 

Yeah it does, 32 or 64 depending on what config you got.

 

please help!! Oblivion is arriving soon and i don't want to fry my laptop
i have a Vaio FE790 running a Go 7600 card. Well, due to its 128MB VRAM only, i decide to overclock it. But the problem is, i want to to push it to the very limit, from 350/350 to 500/390. Anything more would result in artifacts and/or crash. It seems stable, at least after 1 hour of playing Doom 3 my laptop doesn't crash. To keep it stay cool, i purchased a cooling pad but this thing doesn't seem to be effective, as the CPU temp stays almost the same with or without it.
So the question is, is it too risky to overclock that much? And one more thing, should i buy another cooling pad? If yes, what cooling pad should i buy for a 15.4" laptop?
Thanks in advance

 

I overclocked my 7700 from 450/400 to 460/409 and i got a jump of 100 3D 05 points (4250 to 4345). I'm still in the process of ocing it, i only started yesterday.

 

I was talking about the 7400go somebody mentioned earlier in the thread.

But if you could tell me how high you get and the scores with the g1 then that would be great.

 

What are your temperatures at? Also, if you read around the forums, I think the consensus is that memory overclocking will get you much better performance than core overclocking. In my experience, overclocking the memory to much will lead to instability very fast, so be careful.

 

I can't figure out a way to monitor the GPU temp, do you know any? I overlock everything to its limit, i know overclocking memory is much more effective than core, but even if i overclock memory only, it can't reach any higher than 390Mhz

 

how can i overclock my dv9000t anyhow?? I want to push my investment to the limits!!

 

ya but it may be the system buss and memory as the bottleneck, i oc'd the 7700 some more, i'm taking it slow because this laptop has to last me for the next 5-10 years lol

460/409 (4345 05 marks) to 466/414 (4419 05 marks) jump of 74 points, i'll oc it more tomorrow, but from the original i can defiantly tell a difference, i'm guessing that since there's less of a bottleneck since the buss is 667 and the 7700 has 512 ddr2...I'm also overclocking the memory at the same ratio as the core, 9:8 (originally 450:400)

 

Search this forum for the various overclocking threads we have, I'm sure you will be able to find your answer in one of them.

The question you have to ask yourself is, is overclocking worth the risk? If all your games run fine, then I would not trouble yourself with overclocking. Like I said, it's a risk, and you might consider not overclocking to keep your investment safe.

 

As usual, Chaz speaks wisely. (Chaz - great avatar again - my favourite spacecraft after B-wing - it has somewhat bad view from inside while landing, but otherwise....)

Although overclocking can give a great results - if everything works why would you do it? If you want to see it's limits then read some basic info on overclocking, try memory first, then core. Don't go too far. Be prepared to handle Bsods and resets. Do extensive checks for stability. Game. If all works and game runs visibly faster then you reached the goal. It is not hard once you know what to do.

And after all my overclocking mainly for testing (and I scored 3200 3dmark05 in comparison to the default 2200) - I finally found one game that needs all that my old x700 can give - Armed Assault demo. If I overclock - it is playable in 1280x800 with normal settings. Otherwise it looks flat and lame. I could always find a compromise in Fear, Quake 4, Oblivion etc... but now OC is a must.

Cheers,

overclocked my 7700 again...

from 466/414 (4419 05 marks) to 476/423 it got 4504 05 mark...85 points up. It's going well. It's jumped 255 points and I've only oc'd it 16mhz core and 14mhz mem.

 

That's good to hear Matthew, those are very good gains. Keep us updated. Once you reach the ceiling, and you'll know it when you do, throttle it back a little for a safe, stable setting that will give you a good boost in gaming while keeping your card healthy.

 

Thanks. I'll do.

On this chart: http://www.notebookcheck.net/Mobile-Graphics-Cards-Benchmark-List.844.0.html

it says that the mem is 500, when i first got it the memory was 400, (core 450) so i should have no problem ocing the mem to 500, but this messes up the whole ratio of core to mem...if i keep it the same the ratio will be 625/500, wich is rlly high jump for the core (175mhz). mabe the chart's wrong , but it gives about the right 3d score for the card

btw my 7700 obliterates the go7800...woopi lol

 

I've just overclocked my go 7700. i went from stock 450 core and 400 memory clock to 500/445. i can't seem to overclock the memory more that 450 before it starts artifacting. temps went up from ~61 C to ~71 C. 3Dmark06 went from 2661 to 2971. I can get higher core clocks, but then artefacting starts at a lower memory clock... gonna experiment around a little. I used ATITool to do this, because it's easy to test stability with it.

Update: seems like memory won't go over 445. I did overklock the core to 510. now my 3dmark06 score is 3005

 

mobius1aic, did you ever find the drivers to enable you to OC past 600mhz?
