just got my bfg 7900GTX in today. YAY!. got around 10000 stock in 05. then when i oced it to about 705/920, 4400 at 2.72 and got around 11700. running 03 and 06 tommorow.
o and i will be getting another one for sli in about 3 weeks.

Congrats!!!!!Quote:

Yesterday tried the vmem with a pencil and lowered the resistor from 605 to about 570-580 and that allow me to clock the card at 890 memory.
556/890 is my máximum clock at the moment. At this clocks and testing my new 165 at 250x9= 2x2250 gave me 20500 3dmarks 2003 LOL
What is happening when I test at 295x9 -> 2x2650 ???? :):):)
salu2.
I have an VF700CU at 7Volts on it with its blue memory heatsinks.Quote:

It seems to help a bit but the pencil method doesn't like too much to me. I see it very "fragile"
salu2.
The other thing about mods, dont do pencil mods as it is even more dangerous than a traditional mod. I thinks its ironic that users who are too afraid to solder onto thier cards (no offense guys) move onto doing a more risky mod with a pencil. Quite frankly, doing the 10k VR mod will give you more safety and better control over your voltages and its a simple matter of soldering 2 wires which is really very easy not to mention cheap.
i think the attractive thing about pencil mods for me is the ease and the fact i can get rid of it and still get warranty on the product........i have no idea how to solder........i mean i could solder bigger points but some of these gfx card or say PS2 solder points are so small there is no way in hell i would even consider that...........probably best to give it to someone who knows what they're up to i guess lolQuote:

I agree madgrav that solder is much better (its the only way IMO) but to solder successfully you need a very small tipped iron with a steady hand plus a good magnifying glass so you can actually see what your doing :D
Its also very easy to "undo" if needed without even leaving a trace but that takes a little more practice/experience then most ppl have :)
you're wrong. :]
I mean - in almost all means you're right :D, my old 9500@9700 was soldered like hell :). BUT - almost always (i mean if you're using normal iron, not hot air resolder station) you can see if the card was soldered. I know what i'm saying - i work in a computer company (www.angela.pl, www.topower.pl (still in works ;)) www.chieftec.pl, www.sunbeam.pl) and i have plenty of cards on RMA. With pencil/silver mod - you can undone it completely, without any marks :D.
And of course - its more dangerous than a solid soldered MOD :D
EDIT - i have a hot air station at work - but lack a skill to undone mod without marks - if youre watching good enough - you'll see the leftovers.
PS sorry for my english - its not my native language :]
Dave - yeah, these cards are /really/ nice.. and I love the smaller foot-print of them.. I can still see my mobo now. lol. and my chipset seems to run juts a tad cooler, not being smothered by video cards.. anyways..
EDIT: I feel leery about the pencil mod because you have no idea how much you're really bridging the resistor.. it's very "eye-ball and hope" type of cooking, if you will.. I guess if you clean the area well beforehand, and use a fresh pencil, you can eliminate some risk, but not all.. anyways, I am going to do the conductive pen mod to 1.4v after I let my cards break in for a week or two, with tape under it so I can pull it off when I want to... seems pretty tried and true..
My BFG 7900GTX seems to max out around 715/920 on stock cooling/volts. But my 3dmark05 score does not seem right. I can't even break 12,000 with my 4400 at 2.72. I get like 11952, but sometimes my score will jump down to around 10000 on a run or something. Its like up and down. I will get like one good run out of 5 tries. I dont know whats wrong. Then I up to around 730/930 and I start to get really weird purple shapes on Firefly Forest and my fps doesnt increase at all. Am I doing something wrong or is it my card?
P.S. I cant wait for the new RivaTuner, I hate Powerstrip.
You are pushing the card too high. It is throttling which means that 715/920 is too high. Try lowering those clocks until you can get consistent scores. Also the purple shapes are known as artifacts and they are a DEFINITE sign that you are pushing the core too hard. If you want to push higher you need more volts!
Yea, I knew they were artifacts, I had just never seen them look so weird. lol. Thanks for the help I will lower them to around 700/900 and post back later with the scores.
One more question, do you think my cpu could be bottlenecking my video card. I didnt really get the best 4400 out there. I can only run 3dmark05 at 2.7 and 1.74 volts. Do you think the video card is bottlenecked?
Got one of my EVGA GTXs to 695/880 on stock air/stock volt no AS5. Other is still in box awaiting PSU.
Temp is bout 68c load(20c room temp)
Ok, ran it at 700/900 everything went fine scored around 11600. Then I went up to 710/920 and 3dmark05 just quit in the middle of it and went back to windows with a box saying "Nvidia Driver not installed correctly" or something to that effect. My graphics driver was gone and resolution went back down to 800x600. I just reinstalled my driver, but I havent run it again. Whats the problem?
your card is not stable at those speeds...
So ~700/900 is your cards max speed without further modification
damn, that sucks. well looks like ill have to voltmod this one too.
::EDIT::
Most Stable score: 4400 @ 2.65 7900GTX @ 705/905 http://service.futuremark.com/compare?3dm05=1981881
Highest Score: 4400 @ 2.73 7900GTX @ 720/920 http://service.futuremark.com/compare?3dm05=1981686
nvm :)
Thx
C-BuZz
Damned....
Something is obvious wrong with my PC :/
San Diego @ 2,9 GHz
1 GB RAM D43 @500 MHz cl 2,5
Gainward 7900 GT 670/1760 Vcore 1,5V
3d mark 06 - only 5500 :|
isn't this too low score?
EDIT:
Isn't 1760 MHz mem a little too low max - artifact free - mem clock? I saw you guys running them easily 1800 MHz without mods :|. Card watercooled, huge memsinks + 2000 rpm 80mm fan on the side of the card - so i dont think mem artifacts colud be caused by overheating.
@ REVENANT
"you have no idea how much you're really bridging the resistor"
Why? You can always measure it with multimeter - and you know what you have done. Then stick a piece od some tape on it, and voila :D you're done
hi guys, got my opty 165 today and did a first run in 3dmark 2006 ( not with max cloks) and here is the result :
Opty 165@2700Mhz|| XFX 7900GT@650/1700

Here you go something for you to have a go at beating... shouldn't be too hard as you got better mem than mine.:)

:cool:
My old 2006 score with 1.4mod on stock cooler :)) @sinle core Opty Air;)
I change with Zlaman and now my load is same as previous Idle ~50-52* :)) In 2-3 days I'll mod to 1.5v or 1.55v and do some mem.mods and will go for Air WR's with sigle 7900gt :)
Guess this thing had more kick that i though, had some time to play with it today. It'll be seeing vmods and ice soon enuff, but for now this is all stock air/voltage.

revenant, please post your black XFX photos. Especially power circuit with capasitors. Thanks.
Just started testing a Club 3D 7900gt (cheapest I could find, because I'm cheap:D), the Coolbits "detect optimal frequencies" land on 552/ 784 @ stock cooling/ no mods. The core doesn't seem to go much further, but we'll have to see what water cooling and perhaps a Vmod does for it. Temps on stock cooler are about 48 idle, 63 load.
dang, those are pretty high temps. mine idles around 42 and load at 55.
also ive never heard of club, can you post a link to the card.
