Bios Flashing 7800 and OC to 500/1000Mhz - Page 10

360/940 is perfect for gaming 6000 point 3d mark 05 and 70°

i wonder if dell made a special 9400 for you

it is impossible to get to 481 core 980 memory, computer just don't accept it ?????

mod bios 1.3 and coolbit accept 480 /970

you have a screen no??

sorry my english

huh?

how did u do that?
did u modify files?
hows about a link?

I'm playin with the bios 1-2volt.

I have a few questions.

*Is there anyway to lower the 2d volts to 1.0 or even .9? I can drop the settings to 80/400 but will that really do any good?
*there are 3 display settings, 3d, throttled and 2d. Can I get rid of the 'throttled' one safely?
*Can the fan speeds be overclocked? It has a setting in there for fan %.


My vid temps in desktop are stll over 60deg. i wanna fix that.

Is that with a volt mod?

I am running 374/909 and my temp readins approach high 70's

Are you going off i9kfangui temp gauge or the one in the display properties?

I can 3DMark05 ALOT higher than ATITool shows as stable for 24/7 gaming. Sorry, the only point to any 3DMark bench is what is gamable 24/7. The entire point to benchmarks is to tune your system for gaming. Not see who gets the highest suicide shot score (i.e.I ran 3DMark05-06 and it didn't crash and I had no artifacts). Hell, suicide shot scores 7000 is definitely possible running the lappie open with a 1.3 volt mod and a good laptop cooler. Just plan on buying a new vidcard within a few months That said, play Fear for a few hours or BF2 for a few hours and well will see which "overclock" is "stable". Not threadcrapping here, just pointing out the obvious.

People should hit www.dfi-street.com There are guidleines for overclocking and what qualifies as a legit overclock. And number one on that list is 24/7 stability. Period.

Well that said, I will enjoy my much more moderately oc'd system that is actually 24/7 stable (335/835 before going under the hood to make adjustments ). I will say it again: while very cool and resourceful (you guys are obviously incredibly intelligent) I do not know how prudent or wise it is to be oc'ing these things with this voltmod. As any overclocker knows, voltage hurts you more than just heat. It's called electrothermal migration and it can cause a SEVERE degredation of a component such as a vid card given especially the PCB (which does not stably hold the volts) and given the insufficient cooling solution Dell uses for the 7800go in the 9400/E1705.

Still, it has been an intersesting read and it is your laptops to play with. Just watch it. And if someone is interested I would love to post a legit overclock for cards that pass ATITool for at least 30 minutes using the artifact detector followed by 3DMark05 or 06. (or both).

^^^^^^^^^^^^^^

Well, I don't use a volt mod and run 374/909. It seems stable to me. I have never seen artifacts, locked up, or gone over 82. I usually hang between 75-80 under full load (I have fans blowing hard whole time). I think your clock might be a little bit too conservative. 374/909 has been a good 24/7 for me.

Run the ATITool artifact checker and tell me that. Without it at some point it will crash guaranteed. Saying you don't see artifacts is not a real scientific way of doing it.

That is like saying "My system fails Prime95 but it games well and is stable enough for me." In otherwords it is an oxymoronic statement. It is either: a. Stable (and stability is agreed by most reliable sources as running these stability proggies and passing) or b. Not stable.

For me there are no shades of gray when it comes to computer stability. With all that said, it is your computer and you are entitled to run it however you want. I prefer mine to be perfectly stable however...

Mine shows artifacts with ATI tool, but games perfectly. Still too hot tho. The newest version of i9k that lets you set max fan speed all the time stopped reading the CPU temp! So I went to an older version that only lets me set the profile. ie games.

Hmm...
Well, I will download the ATItool to see what happens. My version of i9kfangui is 2.3 i believe (external beta). It reads my gpu at 56 and my cpu as ~35 or so. The main thing is I can just blow the fans all out when I game. Thats the only time I worry about heat. I don't need a profile for that. Its either blowing hard (Fast) or I am just word processing or surfing the net (slow speed).

Then it is not a truly stable oc and you do it at your risk. In the end it is your laptop and uif you are enjoying I guess that is all that matters. I hope I am not seeming like a buzzkill, but I know these lappies aren't cheap and I;d hate for early death of people's vid cards...

no computer is 100%, there are defects in everything. failing prime95 but not being able to crash the computer doing everything it is you do is stable, for you (subjectively), but the objective stable it wont be. but in all honesty, the true objective stable, would mean it could never crash. which is not gonna happen, its all a matter of subjectivity, i dont think this is an overclockers arena, so dont come here acting like his benchmark is bs. if it can complete the test, it is stable enough for the 1 time bragging rights here.

1.3 volts is what the 7800 GTX Go uses, so we dont need to worry that much, the card still throttles at the same time as it did before the mod/overclock. the stock computer runs the cpu up to 85c + with nvidia fan control, so we really arent harming anything honestly.

and yes, i know its a 7800 GTX go without pipelines i checked it has deactivated pipes.

The 7800GTX uses a second heatpipe though.

Really? Well, let's see here. You are overclocking a laptop. I believe the term overclocking is an overclocker's arena yes? I have said repeatedly that it is their laptops but it is not wise to do this mod. 1.2 volts maybe but 1.3 given the inadequate cooling solution and it is not the same PCB even if it is the same core is silly. I was trying to help so we don't end up a few month's later with dead lappies from forum members. I have taken apart and upgraded, repaired, and modded pretty much every consumer model of Dell Laptop made in the last three years so I have at least some knowledge of this stuff. I was trying to add some sense to this discussion.

It isn't one program. This is not drag racing and no one really gives a rat's ass in hell about a 3DMark score in and of itself (at least you shouldn't).The point of benchmarks is to tweak system performance to play GAMES. The vast majority of us are here for one reason: GAMES. We upgrade to a newer laptop even though the old one was fine because of GAMES. So to me it makes sense to make sure your overclock is a stable one so that you can GAME on it.

Hey man I've said my peace but if people insist on insane suicide shot scores as being "stable" for some unknown "bragging rights" in 3Dmark that like .04% of the population even knows exist is your problem. The point of the benchmark is to find a good gaming rate not "Gee, I got (insert number here) in 3Dmark blahblahblah." Seriously, if anyone bitches when their laptop dies because of this voltmod (and some will) I can say I tried to warn people against it. Peace...

we´ll no one can say what the ne GTX PCB will be like, it migth as well be the same of the 7800 go from the 9400 remember the layout is different from the 9300 one so the 9400 GTX might be different too.

I just wanted to mention this, because those of us who are from the old school of overclocking usually do this more often than others do. Has anyone obtained the white papers for the NV GPU to see what its heat tolerances are???? just curious what they list the safe range to operate at. Many times you will find that what we think is the breaking point ends up being under the wire, or over it in same cases.


Just curious.

Unlocking pipes with Rivatuner

Has anyone tried Rivatuner and unlocked the pipes for additional speed?

unfortunately this is not an option for Mobile cards.
hmm, this thread is just a tiny bit naughty really
