You'd better not take that risk, you might blow up the GPU.

**funkflix** · 02-06-2008, 10:16 AM

Hmm okay, will try to get some other stuff. Today i was in stuttgart and forgot to buy some..

**Zeus** · 02-06-2008, 10:19 AM

That's a shame, you could buy one online at www.conrad.de or something if you can't get it local.

Tortured my card some today:

**funkflix** · 02-06-2008, 10:22 AM

Nice one!

Want some 9xxMHz GPU too..

**aussie-revhead** · 02-08-2008, 12:10 AM

Good work guys

I scored a Vapo PE stand alone today and Im going to try to graft it onto my modded G92 to see what it can do .

**funkflix** · 02-08-2008, 10:36 AM

First step done, now i need to fix it on the pcb an do something to measure the voltages.

Finished now. Maybe i will do the mod for Vddr3 later. I have some samsung on it, i think it should be ok without a mod.

funkflix,
Looks very nice!
What brand / model is your card?

**tommithy** · 02-08-2008, 01:14 PM

daayyymmm looks like some mad soldering skillz. got any macro shots of the solder points? How did you do it?

I'm afraid of volt modding my card. don't wanna screw it up.

**Zeus** · 02-08-2008, 01:22 PM

Very neat, i like it!

How does it clock now and what cooling do you have on the card?

Thanks!

It is a Zotac, but not the AMP! one.

Forgot to do some macros of it, but if i will recieve my other watercooling stuff soon, i will do some.

Thanks too! Back in windows now first time with this card, never tested it before.. Modded it out of the box.

First thing now is to get some knowledge about actual nVidia gfx... Last one i had was a 7900GX2. I wonder why rivatuner 2.06 does not work properly with this gfx?

Which tools are recommended for nVidias at the moment?

Will report about results later.

Nice man.

Riva Tuner v2.06 does work with this card but needs a little modification;

If you have RivaTuner installed, browse to the folder where you installed it.

You should find a cfg file there, click it to open, it will open in notepad.

Scroll dow till you find this line: G92 = 610h-61Fh

Now add this line right under it: G92 = 600h

Save and enjoy Riva Tuner.

Thanks, works flawless now!

Damn, i always thought something is wrong with my temperature readings on my 2900XT, bcs. i had always around 29°C idle and just 4-5°C more load. But now with the GTS i have exactly the same temperatures.. Ergo this D-Tek FuZion is some awesome peace of cooler!

(25°C water)

Running rthdribl for about 10 minutes now.

**Zeus** · 02-08-2008, 02:35 PM

Glad it worked out fine for you, now max it out.

**tommithy** · 02-08-2008, 03:43 PM

Run the FUR benchmark. It'll really heat up the card, a lot more then rthdribl. Although it doesn't look nearly as nice.

Get it here

**jason4207** · 02-08-2008, 05:16 PM

I'm not for sure if they need to be sinked, but these tiny chips are sinked on the stock cooler.

And so is the MOSFET shown.

And this chip gets VERY HOT!

Nice mods BTW!

**funkflix** · 02-09-2008, 01:41 AM

Thanks!

I know they are all covered by the stock heatsink, but i have two 120mm blowing above the whole area, for the 2900XT it was enough too.

Can run 3DMark '06 at 820MHz Core with the mod deactivated, now i will try what i can reach with mod.

**funkflix** · 02-09-2008, 03:49 AM

881MHz at 1.302V idle and 1.356V load so far.

Edit: For 900MHz i need to up the Vgpu to 1.394V at load. Still good imho!

**hal2710** · 02-09-2008, 08:02 AM

Hi,

Just read the entire thread.......................

My card is an Inn03D 8800GTS 512mb (G92)

No mods yet.

vGPU 1.110 idle, 1.186 load
vMem 1.902 idle, 1.901 load

Have not taken it apart yet. Anyone want to guess what Memory Chips I have from the voltage readings here ??

Have overclocked with Rivatuner and tested with Atitool (Max find artifacts - Slider fully to the left)

Max best stable clocks are c/s/m 792-1890-1098 fan at 70%.

The FUR thingy gets the card real HOT to like 68/70C (22C ambient) after 5 mins. Is this TOO hot ?? (Stock HSF@70%)

OK, Time for benchies.....................

Hal2710

PS: Must update my Sig.

Edit. Sig updated.

I would say 70c is at my comfort level. I wouldn't go any higher. I bet if you turned the fan up it would run a few c cooler BUT during regular gaming I don't think you'd ever get that hot. Think of the FUR benchmark as the max heat you will ever produce.

**Zeus** · 02-09-2008, 09:01 AM

Funkflix, that is a very good result, mine needs more to run 900MHz stable.

Ran 2006 this afternoon and fell only 14 marks short of 17K, lol.

At least it gives me something to shoot for.

**Alex-Ro** · 02-09-2008, 11:11 AM

Just tweak more Zeus,this is my score just on air and the cpu at the same speed,thinking if i had the same freq on shaders and core i would had 17200-17300.

**Zeus** · 02-09-2008, 11:40 AM

Alex, with all due respect, something is fishy about the way your score is calculated.

Look at this, these are your individual scores calculated, the other one is my score:

Well don't know what to say just that i have the latest patch for 3d mark 2006 and that is the score it showed me

**jason4207** · 02-09-2008, 12:51 PM

There are 2 different scores shown on the screen. 16,693 is in the foreground and consists of 7659/7118/4320. 15,691 is in the background and consists of 7115/6537/4309.

Is that OC'd gfx card w/ hard-mod vs. OC'd gfx card w/o hard-mod?
