New BIOS for P-78 notebooks 9C.23 and 9C.25. Seems like nothing's changed.

I've personally flashed both of these myself so they should be fine. I have yet to see any actual changes though. Fan management seems the same, maybe a little better than 9C.20? But still higher temps than 9C.17. I didn't see anything new in the setup table either. Maybe you guys will see something I didn't.

I'll repost this in the official BIOS thread.

 

why does gateway keep releasing these useless bios updates?

 

9C.20 wasn't useless. As long as you have a good cooler, idle temps (for me) are in the low 40s and you don't have to listen to any horrible cycling fan. Plus the 80C fan turn on thing isn't a problem for me. For older games like WC3 I clock down to 400, 800, 300 and the fan doesn't turn on at all (and GPU stays cool enough) and for newer games I use an overclock profile so the fan stays on and doesn't cycle (and temps will drop to low 70s but not low enough to have the fan turn off).

 

A notebook cooler should help the cooling system of the laptop, not replace it. They should be able to keep the fans running at a lower RPM depending on temperature rather than cycling them. I'd rather put up with 9C.17 even with a cooler though.

Ex.
Temps --- Constant Fanspeed
30~40C --- ~20%
40~50C --- ~40%
50~60C --- ~60%
70~80C --- ~80%
80C+ --- ~100%

Or to have the fans properly controlled based on the GPU load.

I personally don't think the fan pulsing down to 40C and kicking up under load is great but it's better than. 9C.20+'s

Temps --- Constant Fanspeed
30C~75C --- ~10%
80C+ --- 100%

 

"I personally don't think the fan pulsing down to 40C and kicking up under load is great but it's better than. 9C.20+'s"

It all depends on whether or not you work on homework in a quiet room with the laptop close by. Where did you get the 30C~75C --- ~10%? There is no fan at all under 70C for my 9c.20 bios. Also, 80C does not put the fan at 100%, it is more like 80%. 88C or so puts it at 100%.

 

I feel a very small amount of airflow, it seems to be there even though it's very faint, up until it gets around 80+. And if your cooler is pushing enough air into the notebook to replace the internal fans when idle/under a small load I doubt it's quite that quiet, even if it's an improvement over the way the fans act with 9C.17. Oh well, with 9C.17 my temps never pass 70C maybe even 65C with newer games and a decent OC. Under full load (Furmark) max temp is about 75C. I'm going to hang onto this laptop for a long time so lower temps are almost a must for me. =]

 

Even on a bed with no air circulation and in fact insulation from blankets, my gpu sits at 60C and the fan never turns on, cpu is another story but still, battery life is 15 minutes better. Additionally, gpu overclocking seems more stable to me with the 9C.20's

 

I doubt gateway would release an update to make GPU overclocking more stable lol.

 

i would to return to 9c.17 i would to flash a wph file with phflash16 but don't exit version dos of 9c.17?

 

Yeah I'm using 9C.20 and can only overclock the core/shaders to 660/1650.

 

^^ That's a pretty low OC. Try 690/900/1725. Mine is already considered low compared to the other crazy OCs around here.

 

He could have a really picky GPU. Mine's that way. I can't OC it too far, or at least I'd need to find the "perfect clocks". I play with it now and then. I can get 670/900/1750 perfectly stable, I could run furmark day and night at those clocks but if I push the the core 675+ and it seems to drop out within 3 minutes of furmark even though the temps are below 75C. I've also played with voltages and all that, doesn't seem to make much difference. Stock voltages or undervolted the same clocks work and the same clocks drop out. It's been like that since I got my replacement because I was getting BSODs on the first unit I purchased, even though it OC'd a lot better. Also the BSODs were not GPU related. I score a bit over 11.5k in 3dmark06 with 670/900/1750 and my X9100 though, which I'm okay with.

 

PsychoUsagi is right. I haven't really optimized my overclocking, but 676/1690 isn't anywhere close to stable so I just settled for 660/1650. As for the memory, I'm fine with 850 for now until I glue the heatsink to the modules.

"I've also played with voltages and all that, doesn't seem to make much difference." I did read somewhere that the only two voltages that work are .9V and 1.11V so maybe that was right.

 

The core : shader ratio has to be 2:1. Psycho, your shader is too high for your core that's why its not stable.

 

It's actually 2.5:1 that this card uses at 3D extra mode, but I'm not sure it has to be that. I read somewhere that a simpler ratio is better, but I know that Andrew uses 720/1850 which doesn't reduce at all (except for the 10) and he has probably tested to make sure that it is better over 720/1800 (2.5:1).

 

I checked and the fan is off at those temperatures. This plus the pulsing fan control leads me to the conclusion that these fans cannot spin at a low rpm, but this is not to say that much better fan control can't be achieved.

And about my laptop cooler, it really doesn't blow much air through the gpu vent, but it still results in about a 10C temperature decrease at all ends of the spectrum.

 

I wish that were the case honestly, but it doesn't seem quite so. I've tried 690/900/1725 and 700/900/1750 (2.5:1) and at 0.99V, 1V, 1.11V and 1.12V and even so I still have a driver crash in less than 10 minutes with furmark. I've found that furmark tests stability much more quickly for me since if at any time I would get a driver crash by running 3dmark06 or a game, it happens much more quickly with furmark. It's also good for telling "worst case scenario" temps pretty much. Also 670/900/1750 is stable but I guess I'll lower my shaders to 2.5:1 for the heck of it.

 

Hey buddy, listen I used to feel very faint airflow too from my GPU fan a while back with the 9C.17. That all changed once I opened up my Laptop and took it completely apart , cleaning out the gpu vents and fan. Man, what a difference that made. I can feel the hot air blowing out again at a good pace while gaming and my temps stay constantly at around 70 degrees celicius or lower. My clocks btw are what I found to be the limit for my card without causing any artifacts, and those are the ones listed on my sig. People say that blowing some compressed air clears out the vents but that's inaccurate at least in the case of this machine. The dust and dirt gets so bunched up by the vent's exist, there is no way some air could push it out. Also if you decide to take apart your laptop, I recommend applying some new TIM of your choice (I applied some silver compound but a lot of people prefer ICD7) to your GPU and your GPU mems. I believe that is one of the reasons I can keep such low temps while gaming, and should have been applied there by Gateway to begin with. Well now I can definitely see myself using this laptop for a long time to come, so far it hasn't let me down on any of the new games out there

 

Where did that come from? xD I have ICD7 on my CPU, GPU, GPU memory and NB. I already took my laptop apart this year. There was no dust in the GPU because I was blowing it out with compressed air at least monthly, if you don't do it routinely though the dust buildup will become too much to blow out. I did get dust behind the CPU ventilation fins though because it wasn't cleaned as frequently since it's on the back and there's an access panel to it anyway. The very faint airflow was referring to the 9C.20 BIOS management, which I guess I was mistaken about because the fans don't kick on at all until around 75~80C. I am and have been sticking with 9C.17 and my temperatures on fine. The problem I do have is overclocking, but I think my GPU just isn't that great of an overclocker. Any Core clock over 670 causes driver crashes, not due to temperature. I've never seen it over 76C with Furmark and never over 70C in a game, usually in the mid-low 60's.

 

After i installed Windows 7 to my computer it wouldn't let me update my BIOS i would always get this error message, even with the earlier BIOS

"Driver(WDM) Init Fail! (0x137)"

Also my computer has been crashing quite a lot recently. Its not overheating cause most of the times everything is in the 50C. It usually crashes while im watching something. It would just freeze up and then i get a blue screen telling me there was an error and its dumping memory, then it restarts.

 

Have you tried updating with phlash16 and a bootable DOS flash drive? I've done this a few times myself without any problems.

Also these seem to once again be missing the wflash.DAT file, add it to the BIOS directory.

http://www.mediafire.com/?wkty11tiitq

 

All the bios have that .dat file but it still gives me the same error. What is phlash16 and bootable DOS, I'm kinda noob with tech.

 

i need to know which is best driver version for p7805u and how do I install them properly.
Right now i am using
197.16 downloaded from nvidia site.

 

Someone plz move this post outta here.

 

I don't see a version 9C.25 just 9C.23 and just for Vista?!

Does Gateway/ACER doesn't post deltas or history information regarding the BIOS updates?

I wonder if this fixes an issue I have observed with Win7 x64. Everything is great so far. If I reboot, it hangs and never shuts down. If I shut down, it shuts down correctly. Then I press power to turn on. Could that be a BIOS issue?

Thanks!

 

I'm posting up all three bios files for our Gateway P7805U, From my understanding these bios files will work with P78x series notebook, also the acer series dont know the models for them. Just wanted to share! the 9C.25.00 was hardest to locate it was taken off gateways website and off ftp i had to dig deep to find it! keep in mind all these are for x64 installs. Im sure you keep googlin, you could just get the bios files your self! for x86 I think you could use a third party flasher for x86. ohh I take that back 9C.23.00 & 9C.25.00 have both x86 and x64! I'm hosting them from my website. (cramitman.com) versions 9C.20.00 x86, 9C.23.00 x86 & x64, 9C.25.00 x86 & x64 I personaly use 9C.25.00 like it lots better notice almost zero issuses atm but i do know 9C.23.00 & 9C.20.00 had shutdown hanging most often bugged the crap out me! but 9C.25.00 does not...
Good luck! here are the links!

I have located the original link to download it directly from !!!!GATEWAY!!!! the ones i have posted are the exactly the same files but here is the direct link anyhow!

I would LOVE the BIOS fix for the reboot issue but looks like Gateway pulled 9C.25:

Video issues and blue screen may be caused by BIOS 9C.25.00
Gateway Support - Frequently Asked Questions list forVideo issues and blue screen may be caused by BIOS 9C.25.00

Sounds serious!

 

I just flashed Bios 9C.25.00 my wifes P-7805U, we will see. No problems yet.

 

Wow thanks for posting this info! I have to admit i have had random freaky video problems and assumed it was a driver problem how interesting! I had submitted trouble ticket with a tweak software i use video issues have only occurred when using there tweak app which is Tweak7 pretty good tweak app not at the level of there previous TweakXP & TweakVi Video problems only ever happen when i go into Memory Optimize and Optimize the memory! I check mark "try to release as much memory as possible" and uncheck "Do not optimize if CPU is too busy (.75% CPU load)" and this will cause a really tough getting back into your desktop problem. The screen is completely blank pitch black sometimes the video will recover and the screen resolution will be stuck at 640x480 can't hardly recover unless you know what to do! It seems as though the HDMI completely shorts or dies! I end up pressing shutdown button to shutdown windows 7 properly after reboot no issues to mention.

Well sorry for all the details.. Really i have no complaints with 9C.25.00 at all Unless the Video thing that happens is linked to the bios.. can't be proved though not in the windows 7 system logs. only the app that it is happening with!

BTW i must mention all my games run perfectly! audio and video works great and trust me i throw so much at my laptop P78x series with 8GB upgrade i still can tax my system crazy! windows 7 woot!

Peace out!

 

Dyingjedi you should get rid of that 9C.25 so some poor sap doesn't download it.

 

Why, if there is no problems? And if there is flash back to 9C.23.

 

No can do i have posted 9C.25.00 up just for the fact it has worked for me buddy. can't say the same for anyone else. but me it has been better then the others available out there. i guess all in all 9C.17.00 would be the best except for the fact the temps where miss read like cooler then it really was. but didn't have any other issues with the video or anything else neither. statement made by Gateway says 9C.17.00 was a temp miss reading, and cpu or gpu didn't go into better power save modes.. so if you ask me 9C.25.00 is still the best of all the problem bios there really isn't a great bios yet! Until gateway give the P78x Series some more love and update where the problems are I'm gonna keep using 9C.25.00 and going to keep it available to the public i guess i could also post the direct link too get from gateway. Matter fact i think I'm gonna do that gotta locate it but ill put it up. OK here it is..

U will fine the official release for our laptop here. direct form GATEWAY.

ftp://esupport:[email protected]/pub/hardware_support/drivers/notebook/P78/

Here you will find that it is still public at the american site. =) Goodluck guys happy computing.

sorry to burst everyone's bubble but they have taken 9c25 off the above site as well.

 

I believe it was removed off the Gateway Website awhile back by Gateway, that's why dyingjedi posted it on page 3 post#26.

 

Please note some reason the other ling behind the visual link did not stay orginal please use the login and password showen and you will then see the correct 9C.25.00 post in with the rest.

What does 9C.23 do? I only find 9C.20 changelog on official gateway website and couldn't find any related info to 9C.23

 

Not only that, but 9C.23 seems to only be available for OS Vista, and Windows 7 seems to be only for 9C.20. I am confused??

Also, every other time I view the website (mentioned previously), it shows 9C.25. But when I revisit the website later, it is gone. Weird!

 

I flashed 9c.25 with win7 x64 with no issues. Run as admin, disable your anti-virus. Bios in not os driven, just the installer.

 

im in win 7 x64.i flashed 9c.23 since my 9c.17 was corrupted, it couldnt read all my RAM, it makes just 2,99 GB usable.

what can i say from 9c.23, is.... HOT! idle at 68c

but im too scared to roll it back to the not-corrupted 9c.17. when flashing to the 9c.23 i was terrified because ive done something stupid to my laptop before that caused the vga died.. and when the flashing to 9c.23 was successful, i was very relieved. and i think i wont be flashing anything until i get my guts back, lol

 

It is likely web pages stored in history. Clean up history and try again.

 

since 9C.25 got pulled by Gateway, it never got updated to Win7 I guess, I did flash under Win 7 as I said before. Vista and Win 7 are very similar. I have been using 9C.25 for a week now, played SC2, and lots of other tasks with no issues so far. My CUP, GPU have no heat issues either.

 

I initially thought the same thing but Nope... tried a different browser altogether. Note that JUST YESTERDAY the 9C.25 file wasn't there. Now, it is there!

Granted, I won't deny that my ISP could be cacheing the FTP server but I highly doubt that.

 

You can try other DNS server if thing continue to go weird on you. OpenDNS is a free DNS server and there are other free DNS server to choose from as well.

Back to topic, so I guess I'll try out 9C.25 and see for myself.

 

I have had no issues with 9C.25 two weeks so far.

 

Is this problem related to win7 or bios v17? How many of you have this?

"If I reboot, it hangs and never shuts down(I should press power to turn it off). If I shut down, it shuts down correctly. Then I press power to turn on."

 

how can i find 9C.25 change log? i havent found this bios

 

Download 9C.25 here I think

 

I had the same problem with my P-7805U FX, I had to disable the IEEE 1394 Compliant Host Controller (not too many people use this anyway) in Device manager, for some weard reason that was to problem. I hope this helps.

 

I have been running Windows 7 on my P-7803h with the 9c17 BIOS since I got it when Windows 7 came out, no problems at all... I did check a couple of weeks ago for a new updated BIOS for my laptop and the Canadian Gateway website told me to use 9c23.00 BIOS (only option for the P-78XX FX series) never said anything about the 9c20... But staying with 9c17 as the temps on the GPU are much lower...
