Official 7900gs Overclocking Thread

The memory is DDR, so double the clockspeed. 500MHz * 2 = 1000MHz.

 

more scores and info in the link in my sig.

 

Couple errors in the original post.

- The M1710 comes with a dual-pipe card, the E1705/9400 comes with a single-pipe card. You can install the dual-pipe in the E1705/9400 with minor modification. No E1705/9400 laptops come with a dual-pipe card from Dell.

- Stock voltage of the Go7900 GS is 1.0 volts. The 1.24 voltage ROMs are overvolted to allow for higher clocks.

 

Sounds like I won't be using these roms. I'm not familiar enough with hex editing to get that done... wonder if anyone on the Notebook Forums has done an OC on this thing. I'll check it out.

 

FlashSVT, is the 5150 Joker's bootdisk from your thread the same as the one linked to in this thread?

 

ahhhh!! what happened?

i was running at 420/1100 fine for a while, got 6928 3dmarks, played hl2 well for an extended period, so i decided to go up to 430/1250 (at 1.00v, not 1.24) and run a 3dmark05 bench again. suddenly, halfway through the first test, i get a blue screen saying theres some memory parity error and the system has been halted.

i started up again and loaded stock clocks, and decided to rerun 3dmark05. the hardware is fine, but when its going from like the second to the third test 3d mark always encounters an error and has to shutdown. reinstalling it to see if it'll do any good, but what happened? my temps weren't even bad, didn't hit above 70 at all, averaging 65 or below.

edit: the reinstall fixed it, im back to a calm 6388, which i'll be sticking with for a while, but am completely happy with

 

I'm gone from there now anyhow, but I still maintain that I should have been able to have my scores posted there even though I have the M1710.

 

1250 memory is extremely high. Try lowering it to 430/1200 or 430/1150.

 

Yes, he is the author of the bootdisk. I was the the first to use the bootdisk and worked with 5150 Joker through the first 5 revisions as the OC guniea pig.

 

Yeah, my card is one of the better ones around, but if I go up to 1250 I'll get a BSOD every time too. Bring the memory down a bit and you should be able to be stable once again.

 

alright, the memory is back at a cool stock 1000, which i did immediately after i got the BSOD, but if i got it to do that on me, have i done serious permanent damage?

sorry for the freakout, but this computer is barely four days old, and i'm gettin a lil overprotective

 

Whats a good way to test your OC? I flashed my 7900gs to 450/1100 and I ran 3dmark06 5 times in a row and ifan8gui says a max temp of 71C. I'm not sure how accurate it is. is there a better GPU reader as well?

Thanks.

EDIT: one more thing, the first time I ran 3d mark after flashing I got a direct3d error, but then it made it through 5 loops. Also is there free program that will show the clock speed of the card? I thought the Nvidia panel did it but with the new interface I can't seem to find it. Also 3dmark had 0's for the categories.

 

Use your Nvida control, under monitor temperatures, panel to calibrate I8kfan, ya have to add about 8 degrees under the I8kfan options in most cases. It does not report clock speeds, use another utility for that.

Use small clock increments for safe clocking, going from stock to 600/1300 is asking for a small thermo nuclear meltdown on a single pipe system. Hopefully “slow protect” will save you but I’m not taking any chances.

When testing new clocks I leave i8kfan running in the background to maintain a temperature log for 30 minutes or so. If nothing BSODs or hangs, then run a game, NOT OBLIVION, beautiful but a POS in programming and seems not to like any OC on my machine, for a least on hour. I’m happy if temperatures are not over 81C, but YMMV.

As far as synthetic benchmarks go, I don’t have much use for them, I play games! But of course the benchmark numbers are fun.

 

Well, what about the games!!!

How are your games in OC mode? I’m running 500/1100.

FEAR V1.05 runs fine, except for Interval 8, with minor texture corruption on a few but not all scenes. Turning slightly makes them stop “flashing” in most cases.

Doom 3, ROE. Totally awesome! Carmack and his programmers are top notch, no problems of any kind.

Oblivion - OC or not, patches or not, I have tech issues with this game. This game, on my 1705, in OC, is pretty touchy. I can play 10 minutes or an hour(s) then get Errors and quits or locks up. Normally I get the errors going through doors which are supposed to be fixed with a patch. I get minor texture flashing on this game as well on certain scenes.

Anybody else? How’s BF2 OCed?

 

Right now I'm running 550/1100 and playing Oblivion for hours at a time causes no problems. Yes it does get hot and peaks out at about 81C-83C.

 

So your running even harder than I am, no texture errors? No crashes at Exit? What version are you using?

At least I'm not alone...just search google.

 

I generally run atitool's artifact scanner for a couple hours to test stability.

 

I haven't noticed any texture errors at all. The game doesn't crash on exit, but it does crash occasionally (in middle of game for no apparent reason).

I'm running the latest v1.1.511.

 

Good idea. I haven't run that guy since my ATI M10 9600 days.

 

haha same 9800 days for me as well. i just parted with my old 9800pro too

 

Question. 375/500 is alot cooler than 450/550. I'm concerned about battery life with the fans running all the time. Can I keep reflashing it from stock speeds to OC and back over and over without ruining the card?

 

Welcome to the forums!

When running stock and OC, IMHO, would never suggest running on a battery when gaming. Until ATI and Nvidia find away to run a near desktop GPU processor with out a heat and high current budget, this is the price we pay.

Modern EEProms can be flashed many times without problems, this not to say something will not go wrong during the flash process.

If something does go wrong we all face a $350 or so chip replacement, no?

 

Thank you ^_^

Yeah I tried that once and the battery died in about 40 mins >_<;

That's a little scary. ^^; So say, excluding any worst-case scenario power loss situations, flashing it once a week for the next 3 years? Is that way into the "you'll destroy it" end of the spectrum?

Thanks, ~Shaddix

 

7900GS ISO - best burned with A120% -

An excellent substitute for Alcohol 120%, IMHO, is a free program by Lightning UK is Imgburn http://www.imgburn.com/

Lightning UK is the author of the banned but excellent DVD Decrypter.

Imgburn also has newer burner support...I have to hold the Plextor down when using this

Yes, at exactly 172 writes you will suffer total EEProm failure!





Sorry, couldn't resist...I would google "GPU write or flash failure" to get any data on that.

However you can go to this site to see if ya get any bytes

OMG MY COMPUTER BLEW UP DONT DO THIS









-jk

 

Um why are my temps a lot higher after doing this. I use to idle around 58-65, now im idling around 70-85. Help!
(450/1200)

Edit: OMG, I'm a noob. I had I8kfanGUI set to track GPU fan. It must of disabled it.
BTW, is 4170 in 06' a good score (450/1200)? I've seen some people get higher and I was just wondering if mine was ok.

 

Temps can be very tricky and are different for everyone. My advice is to get I9kfanGUI and set it up to keep everything cool. Im actually using it now because it doesnt take up tons of resources like I thought it would. That is a pretty good score, I had a few points higher with the same clock. Ill add it to our top scores BTW.

 

I keep seeing people reference the Go 7900 GS as underclocked by Dell, which is slightly confusing since from what I can see by searching Google, that's the way it is for all manufacturers.

At any rate, I was looking through the 3DMark thread and I think there should be a breakup between overclocked cards and cards at stock speeds. Not everyone will overclock or even realize that's possible, and will just wonder why their computer is getting a lower score than it supposedly should.

Can anyone post pictures of 3DMark05 results based on stock speeds and then slightly overclocked speeds (450 1100 seems to be the safe overclock)? I'm considering an E1705 because of the option of having the 7900 GS in it, but I would like to see stock benchmarks so I can compare with other alternatives to see if it's really worth the money. I'm not quite sure if I'm comfortable with overclocking, since I'd much rather have something that works to its full capacity under warranty conditions...

Thanks!

 

The 7900GS even at a stock clock is a very powerful card. Its stock clock is sorta low for a card of its power, and many found that taking it higher was not only safe but in some cases worth it. I think everyone here would recommend a 1705 with the 7900gs; its one hell of a gaming machine and a powerful workhorse.

With stock clocks youll see scores of around 3750 in 06, somewhere in the 6000 range in 05. If you oced the card around the 500/1100 range you would see your scores jump to 4500 and 8000. This means nothing to me, so I tested my games out. In FEAR my average FPS in the stress test jumped from 40 to 47. HL2 I saw a 10 fps increase. This equated to about 20% increase in FPS. I oced it about 20% as well to 450/1100. In my mind, its worth it. The card can handle it and it helps in the games.

Hope this helps you out.

 

I haven't benched it at 425/1100, what I run every day, but stock I got 3520 in 06 and 6377 in 05. My super-overclocked and overvolted scores are in my sig.

 

umm i dotn get it, why cant you just download power strip and overclock from thier, or unlock the advanced features of the nvidia drivers, ten times easier than all that crap?

 

I dont understand why you go thorugh that whole process , cant you just download powerstrip and OC that way, or unlock the advanced featured in the nvidia drivers using the registry entry,?

and one more thing, wouldnt OCing your video card Void your warranty?

 

Dell locks the GPU Roms so we have to use the side door

 

And they are supposed to know how exactly? (Ethical questions aside that is).

 

Your thread has been merged with this one because it deals with the exact same topic . .

 

using Nvidia's Clock Frequency Settings, i cant do anything. Firmware 84.69. Manual overclock setting and hitting detect optimal frequencies does nothing. Adjusting the two slide bars and testing it no matter what always fails.

Any ideas?

 

You cant overclock a Dell 7900GS with drivers or programs. You have to flash the GPU rom like my instructions on the first page of this thread. Read that and then ask us some more questions.

 

I flashed it with the v4851100.rom, since that seemed like a good boost and a safe overclock, but with I8kfanGUI 3.0 beta 5 and both fans going at the very least at slow speed, it still seems to idle around 59, and sometimes jumps up to 70, but quickly falls back down. Is there a temperature offset I missed or is it really running that hot?

 

Be very carefull and read the DOCS!! You are using an overvolt clock with the "V". Since you have a 1705 you only have a 90W supply and risk heat damage. IMHO I would use the same clock without the "v".

Happy Clocking!

 

Guys,

OT, please jump to my hardware thread concerning default 7900GS idle temps.

Thanks all

 

Fixed. You're a king.

 

Anyway i can OC my 7900gs witwhout voltage mods and without flashing bios? ( safely of course) And clock speed hacking tools?

 

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO.....lurn 2 reeed

 

You can OC without the voltage mod part. Read the first part of this thread then ask away. DL the ISO image to make you a boot disk which has to used to bypass the locked BIOS. I would try a safer (No "V's") 450/1100 clock which many people seem to like full time due to heat build up. Please understand that any risks are your own

regards

 

ok seems like most on this thread have the dell e1705.my ? is how well does this machine perform on oblivion when not overclocked. here is what i am thinking about gettin 1.83ghz core duo 1 gig 667,and definetly a 7200 rpm hdd with the 7900gs

 

A stock 7900GS outperforms a OC'ed 7800, so I can "sorta" answer that question for you.

With my old 7800 OC'ed, I had most on medium settings, large textures, spectacular distance on 1/4 with tree/building/view distance on full. I had AA, bloom, and grass OFF.

Inside building, I was running around with 50-70 FPS and outside was 20-35.

Since your using a stock 7900, I guess you can expect a small FPS increase vs my old 7800.

 

cool thanks for the response eth i had already got a reply in another thread but that person had an overclocked one i was curious as to what it would do stock thanks again

 

I saw a guide on the net about overclocking the Go 7900gs in the E1705. So I overclocked mine. I Put the voltage to 1.24 at first. But Since its a laptop I didnt want to mess anything up. I put it back at 1.00 ( Factory voltage)

Stock Speeds are 375/500.

I loaded the baby on a overclock at 480/1100..nice..got 8K in 3dmark 05...but too hot.

And I don't want to take life off the laptop.
So Its at 420/1100 now ( 375/500 is stock)

Is this safe? My temps are 60C max sometimes 61 62 most when Doign regular tasks and 65-82 C While gaming. I saw in a guide 90C is when your GPU starts to get damage. Is this safe? I mean it doesnt seem like that big of a overclock.

 

My 7900GS in 3dmark 05 at 420/1100 is just about EXACTLY how fast a go 7800GTX is. ( and thats preety dam fast)
