7800GTX Overclocking for Idiots--BOOTDISK download Included! - Page 18

Hey guys, this forum is great, especially the Dell forum. I have an m170 with 7800gtx. Since it's still in warranty i dun wanna open it and apply AS5. So, is it safe to flash the bios of the GPU ( stock to 440@1200 ) and leave it on 24/24. My GPU ideal's temp is 62. CPU is somewhere around 40-50.

Ahum... I thought that 95c freaked me out, you should've seen me when something openend up a barrel of artifacts you wouldn't believe!

I was getting all depressed like until I checked the clocks... seemd that auto OC pushed it up to a whopping 486MHz.. no wonder.
What idiot created this function?

The function of the auto overclock feature. It methodically tests your hardware for the highest stable clocks when it enters 3D mode. However, since you enter 3D mode in a "cold" state, the applied clocks will many times be higher than the capabilities of the card. Therefore, the only way to get an accurate auto overclock is to heat up the card first and then apply auto oc. Defeats the purpose, no?

Hey, I think I'm at the right place for questions.

1.7-->2.26Ghz at 1.196v. Did 14 hours of Priming and found it stable as ever.

Played 45 mins of Fear and did not see a hitch.

CPU Temps 29 at idle and 60 with Prime95.

Now for some OCing. Can anyone direct me to the right ISO file for OCING. I looked throught this thread and managed to find 3 different ones and I am confused about the right one. Should I just follow the instructions on Page one of this thread to make the GEN2 (with the 7800) Overclockable?

Thanks, just need some encouragment to do the flashing thing .

dead 7800 go gtx

ok ,
i nvflashed my 7800 gtx a couple of times trying out the new clock speeds using the bios.rom/cd bootdisk for idiots --- wow great 440 core 1250 memory
i decided to try 450 core and 1250 memory but during the "nvflash" the program stopped for about 3 minutes- i panicked and tried ctrl/alt/del -no luck -then i turned off the power thinking that this would abort the 3 min stalled flash
when i turned back on the laptop - the screen was black "dead"
is there any way to "blind-flash" back to a usable/working bios?

xps gen2
2 gig memory, 2.26 cpu, dead gpu
thanks

Welcome to the club!

You can check my story out at the bottom of this linked page. Same timings I tried.

dead 7800 go gtx

wow i though i had a brainstorm
to leave the motherboard battery plugged into the motherboard(i popped it out of its socket -tough though - double sided tape ) so i could remove the xps top cover without loosing the mobo settings...
after setting the dell bios to boot directly from the cd-rom without having to hit keys etc.---i used my 6800 go to see the correct settings, then i saved the mobo setting and rebooted the laptop with the "bootdisk.rom for idiots" in the drive-after putting back the dead 7800 go gtx, but with no luck (i ran 2 pre-trials with my 6800 go installed, and the bootdisk reved up and went to the R prompt,twice, (to double check)--- but with the dead 7800 go gtx the cd drive wouldnt boot up - now that's odd!
why would the dead graphics card affect the boot-up?
putting back the 6800 go

any ideas?

Simple, a normal desktop system also stops the POST when it doesn't detect a working videocard (well, depending on the system and the bios settings obviously).

Maybe want to try a hot swap? (works for bios chips)

Hot Swap? as in booting to the R:/ prompt with the 6800 card... then removing it ---adding the 7800 gtx and then flashing the 7800?

sounds risky- will my 6800 card get destroyed or perhaps my motherboard?

is this a "standard procedure" for experts?

what do you think the odds will be of killing my entire system?

Never done it with a GPU BIOS but I've done it a lot to upgrade BIOS chips with a hacked image. Yes if not done right it can go bad.

It is risky, but if you're feeling lucky and put a blindfold on then it won't hurt... much.
Me personally, I wouldn't do it. But if I was saddened enough that my pretty 7800 was lying there, dead, I just might.

But since I don't want to be semi-responsible for killing your system, I suggest you forget what I said.
(imagine the horror if other people too read it and give it a go... I could be held responsible for dozens of XPS's deaths!)

What a delima

I put back the 6800 ultra

used NiBiTor to make some clock adjustments from stock(450/1060)i.e.450/1100 , 450/1200 and 475/625 ie 475/1250--- saved the bioses then...

burned a cd with the new bioses and a few files from the bootdisk.rom for idiots from the 7800bootdisk.rom ie: nvflash autorun (one of the 7800 files for good luck 525C1200.rom) cdwsdpi dos4gw Cornholio_CD nv513 ORIGINAL.rom

next i rebooted my laptop with the 7800bootdisk.rom for idiots

then i "hot swapped" this 7800cd with my new 6800cd (with the 6800 overclocked bioses on it) at the "R" prompt

hit: dir/w to see the file names - (the file names were different than what i called them; my 6800ultra.rom was something like 680_0ul.rom ---odd huh)
anyway i used the altered file name as dir/w had given

hit: nvflash 475C1250.rom(ie 680_0ul.rom)
hit: y waited
update was sucessful
hit: ctrl/alt/del rebooted and it worked!

tried flashes:
450/1100 stable
450/1200 stable
475/1250 stable
i read that the memory on the ultra is rated 1200 and the stock ultra core was 450 so core up by 25 and memory up by 50 seems a good place to stop - after killing my 7800 go gtx

"hot swapping" the cd at the "R:/" prompt (7800 with the 6800 altered bioses ) has no risk?

3dmark 2001 = 24,610 3dmark 2005 = 5,807

Pin Modding 2 the Nth degree?

hey,

now i want to buy a 400mhz bus cpu for the pin modding trick, but which ones will work?

1.7 ghz 400 bus, will yield what 533 bus ghz's?
1.8 ghz " " " " " ?
2.0 ghz " " " " " ?

Simple math my friend, from 400 to 533, what is the perectage increase in fsb? That is the same percentage increase in CPU speed.

1.7 yields 2.26, 1.8 yields 2.4 and 2.0 should yield 2.66 if you can find the right chip. My super chip will do 2.4 at just 1.276v so I'm sure this core could go a LOT higher... but the multis won't.

Here you go...

Intel 725 (1.6) runs pinmodded @ (2.13)
Intel 735 (1.7) runs pinmodded @ (2.26)
Intel 745 (1.8) runs pinmodded @ (2.39)
Intel 755 (2.0) runs pinmodded @ (2.66)
Intel 765 (2.1) runs pinmodded @ (2.79)

Note that if you want to pinmod the 725 and 735 are best as they really need to voltmod, are quite cheap and good chances of them working. The 745 will require a voltmod to be 100% stable and stands less of a chance to work. The 755 is gonna cost you a lot of cash, less than a 7% chance of working and requires a voltmod. A few people are selling these and say they are tested to work but are charging an arm and 2 legs for them.. I've seen 425 being asked. The 765 will not work since a pinmod is going to push it above the limits of the processor.

Not always, I didn't need it. It all depends on your luck.

I thought the theoretical limit was 3.0ghz?!?

And I wouldn't mind paying extra for a high-end golden sample of the 400mhz Pentium-M's. No voltmod = Jax happy.
