Helow, few weeks ago i modded my friends asus 7800GTX and its a real clock ass :banana::banana::banana::banana::banana: :slapass:

This score i got yesterday

http://www.belgium-coolingsolutions.be/Pics/overclocking/7800GTX/20K.JPG

compare 2003:http://service.futuremark.com/compare?2k3=4410129

THis is the max i got with it An hour ago.

compare 2005 http://service.futuremark.com/compare?3dm05=1463536 :slobber:

Custom SP94 onto 7800GTX:

Complete Rig:
http://www.belgium-coolingsolutions.be/Pics/overclocking/7800GTX/extreme_rig.JPG

its almost fully tweaked with the standard tweaks out there, memory isn't optimised yet.

THis is Done on a DFI RDX200/superflower550W psu.

i know this card is going to slap some ass with better cooling on the core,
wednesday the cpu is going under -25 chiller so 3G+ should be near.

The card was running at 1.78V, vdd isn't working right now because it came loose.

omg Q-tips! lol

nice score. wow, no memory cooling??

Jort

11-20-2005, 05:55 AM

it was like 8° in my room, and my friend took the memsinks with him few days abo.

wednesday he will bring them back:)

Ubermann

11-20-2005, 05:59 AM

1.78 ? Is that safe ?
I had mine up to 1.65 so far and didnt know if i would dare higher cant find any info.
You get nice boost up to 1.55 and then it scales bad ?
I have 10660 so far with 2.7ghz single channel.
What speed is your GPU running ? And how is temp on GPU when running 05 ?

Jort

11-20-2005, 06:15 AM

yeah shamino used 1.8V on his aircooled 7800GTX,
About the boost you right.

few days ago i gave 1.7V and the card did 610 mhz with delta, now with 1.78v 675mhz max.

gpu @ 675 and mem @ 1434 mhz.

can you give a compare of that run? and what cooling?

AND notice this is On an ATI mobo :p:

Ubermann

11-20-2005, 06:50 AM

Its on air with a prescott cooler on GPU and XP-120 on CPU.
Will give you the link as soon as i can reach the ORB but it seems down ?
It was 604/1737 (642 delta)
Nice of you to post, cant find many with single card and air cooling here =)
Gonna up that volt now and see what happens..

Jort

11-20-2005, 06:55 AM

don't up the voltage please :p:

tnx for the info uberman, normalt the vdd is fixed this night or tomorrow.
then i'll bench again, the mem did 1600 with stock cooler before.

greetz,
Jort

ps: what drivers where you using?

Dynasty

11-20-2005, 07:34 AM

1.78 ? Is that safe ?

Yeah, I use 1.74-1.77 with water.
On my Vapo LS mounted onto 7800gtx I used 1.86Vgpu.
These cards are very volt hungry.

@Jort what idle temps you see with the SP94/fan combo with your gtx ??

Jort

11-20-2005, 07:36 AM

31° idle

and yesterday it went never above 48° stressed

above 1.8V lockup at GT2 when running 10 seconds of the test

Nice temps, gotta love them SP94's they come in handy.

Maybe put an Panaflo or Tornado 80mm for more air power. :cool:

Jort

11-20-2005, 07:59 AM

yeah dunnow where to get them here. idd i was amazed by the temp of the gpu.

installing the SP94 on it ain't easy because the holes are about 1mm of the side:)

Ubermann

11-20-2005, 12:52 PM

I used 77.72 drivers, what are the latest approved drivers ?
I tried some others but this ones seems to be fastest for me, plz tell me if there are any other better.
I still cant get into futuremark site !?

troid

11-20-2005, 01:31 PM

Yeah futuremark still down :(
We also only tried 81.94, 77.72 is no go atm since we dont have the no cold bug bios and we don't have a floppydrive to flash it.

Edit:

Jort is fixing vddr atm.

Ubermann

11-20-2005, 01:54 PM

I use cd-rw cd + ultraiso +flashcd.iso for all flashing.
Gave up floppy long time ago..it does not feel safe =)

Jort

11-20-2005, 02:09 PM

tnx uberman for the info, i'll burn a cd today and flash tomorrow.

the vdd is pain in the ass, when i solder the wire of the vdd to an alternative point the card is refusing to boot:(
without the mod everything works flawless.

Ubermann

11-20-2005, 02:30 PM

The ground point ? You sure resistor is set at 100K ?

the "aircoolmod" on the 7800 is very impressive...not to heavy for the PCB?

Ubermann

11-20-2005, 02:42 PM

Gawd it looks horrible at that zoom =)
The trace goes to the small resistor just next to the bad point right ?
You use thick wires ? Whats that dirt around bad point area ?
I used cut IDE wires, im to scared to use any thicker then that cuz of the heat soldering it on.

Jort

11-20-2005, 03:30 PM

Your right it aint look pritty with hyperzoom.

i need to clean it off with some alcohol but it doens't change performance after all.(rosin flux)

the wires are good, but the mod not:(
i'll wait for the reply on my mail to someone:)

edit; i tried to solder the wire to the little smd resistor, same deal ;)

Jort

11-20-2005, 03:31 PM

support the card by putting something below the cooler:)

Ubermann

11-21-2005, 05:58 AM

Edit:

Jort is fixing vddr atm.

FM is back online, however 77.72 still seem to be latest FM drivers for Nvidia.

Ah ok jort will flash the bios tonight, so we can use the 77.72 drivers :D But he is still at school atm so expect an update this evening or tonight.

77.72 with temp disabled is no fun when running air :(
I have 10814 (http://service.futuremark.com/compare?3dm05=1467087) so far but thats with 78.03.

I really hope you get it working again.

Jort

11-21-2005, 11:03 AM

TADA, Shamino gave me the pic where you need to remove the resistor.

ITS WORKING!!!

Uberman i am after you^^

Ubermann

11-21-2005, 11:22 AM

Great!
I had it up to 1.78v but screen goes blank, dunno why maybe weak PSU.
Need 1.8v for 11K i think.

Jort

11-21-2005, 01:18 PM

http://service.futuremark.com/compare?3dm05=1468378

pushing pushing ;)

1.8 ovp kicks in, i have the same problem.

Ubermann

11-21-2005, 01:31 PM

Close =)
What Vmem are you giving ?

troid

11-21-2005, 01:38 PM

2.45vddr

Jort

11-21-2005, 02:37 PM

benched at 650/1700 but i think my psu cant handle all the stuff.
vdd @ 1.55V

your score will be for tomorrow, i am tired and need to get some sleep to get up early.

Ubermann

extremely good results + nice mods
I like it very much :D
:toast:

Jort

11-21-2005, 03:02 PM

Getting throttling ? Sometimes i make good run but bad score and dont know what to change, volt or clocks.
3Dmark consumes alot of time..
And its not funny with high volts, every run feels like it will be the last before card dies :p:

not kidding me :stick:

your 100% right, and pushing the max out of it ain't a walk in the park.

damn GT2 lockup's :slapass:

but tomorrow is another day of benching on air, then after that the day of chilled cpu cooling is there. :D

so tomorrow prolly the last day on air, i need to get some magic power to break the 11K :slobber: on PURE air :woot:

Ubermann

11-22-2005, 11:49 AM

Any updates ?
Im gonna try 1800 on mem, might end with a kaboom =)

You was first! Im still waiting for my room to cold down.
Should be -15c outside but its +1 :mad:
More beer more volts and i HOPE i can beat that.

Jort

11-22-2005, 12:29 PM

is this the wr? cooled everything on air:D

if not, i need to push more i guess

Ubermann

11-22-2005, 12:32 PM

I dont think so, must be more insane people out there =)
Think 12000 or so is record.
81.95 WHQL is released, will try those.

Aha so what is the WR ?
But you need 77.72 for WR to keep it fair..

I can't wait to see more. Do your best and I might post something down at tng :p: .

Spend some hours with lockups in GT2, didnt get to finish one run =(
Having problem getting it to run at 648 shader clock.
Will change delta and try som more later..
Wonder if i should use a separate psu for gfx..I'll be back =)

11-23-2005, 08:08 AM

Bravo Jort!...That's the way to push to mem clocks on the card. You should freeze that whole setup and try for single 7800gtx 256mb overall WR(shamino). 11,950 can take it..I think you have the card, the board, and chip to do it ;).
This is the intel/dothan single 7800gtx WR(I almost caught sham at the end there before I sold my cards). You can take it.:

11-23-2005, 12:40 PM

Tnx master^^

Today nothing was running like it should.

GTX vdd came off, gtx vdd was 0V arties like rain.

then my friend Tim got home, and i tried to get the mod working again.
So its back oke, now the first thing i am going to do is get some hotglue and attach the mod so i can trow with it without killing it:D

This is how i am going to do:

- Install latest drivers
- Get some sleep
- Flash the bios
- Try to fix a Mach running for the cpu.
- Try to attach my chiller to the GTX

if nothing works only 1 thing left. :slapass: :slapass: :slapass: :slapass:
slap it till it flies :slap:

btw when the cpu was on the chiller we had 53fps GT1 :slobber:
2950 ghz ;)

greetz Ya All

Till tomorrow a brand new benching DAY :banana: :banana: :banana:

77.72 is not very fast compared to newer drivers..

Any updates Jort ?

Jort

11-24-2005, 02:14 PM

cpu won't fly here.

and the noncold bios doesn't clocks as high like the stock bios.

2900mhz on mach2 seems max of this cpu,

77.72 is truly slow compared to 81.84

Ubermann

11-24-2005, 02:32 PM

Use Nibitor and turn off temp monitoring on your stock bios and flash it again.

My last run 702/1778 (http://service.futuremark.com/compare?3dm05=1480056) so god damn close to 11K but i wont make any more run, 1.77GPU and 2.72MEM.
Its +1c outside and now im gonna pack everything down and move to new apartment.
Hope you break the record, even if you wont its still fun =)

Jort

11-24-2005, 02:47 PM

tnx for the tip ubermann, i will try to break it. this is my goal.

its 3° here, damn cold, typing with frozen hands:D

good luck;)

got bad contact... so i have to fix it! also vmem got off WTF... need to do something again no benching today but tomorrow its fixed and i can join the party ;) (lol got 72 and then 52C, yes PLUS (+) degrees, with cascade need to fix evap contact)

Every bench session is start all over, i flashed the stock bios again because the noncold one sucks hell.

max with the non coldbug was 643 mhz,
and with the stock bios 673 atm.

i don't understand it because past week i got 684mhz.

hell yeah i'll keep pushing this rig till i got what i want.

Ubermann

12-05-2005, 10:35 AM

What are the difference in bios except delta and clocks ?
I see .00 version and now up to .68 version but i cant find any difference in Nibitor.

GoThr3k

12-05-2005, 10:49 AM

check out the bios mods in the VMODS or BIOS section
a difference of 300Pts for sure with other delta
