I've got today my second 8400GS, it's a Zotac non-low profile edition :eek:
http://www.noticiastech.com/wordpres...otac_graka.jpg
can't wait to get home and try it :D the pwm area looks powerful, and has 256mb of hynix 2.5ns memory, i only need to figure out the vmods :rolleyes:

hey oohms good on ya for posting those mods :up: :up: :up: :up: :up: :up:
Andy judging by the pic in your sig youre having lots of fun with this card :D
My D9s are dying, lots of error left and right so unfortunately I cant bench until I get new sticks.
Yeah, I'm luvin it. Du du du du doo.... hehe.Quote:

More mods done:
http://i30.photobucket.com/albums/c3...s/PICT5246.jpg
I also found a voltage source of ~2v that goes to the GPU core, ill do some more testing to see if increasing it will help my overclock :confused:
Nice work ! Is that brown cylinder a very small tank of LN2? N20? :D
Good luck!
Regards
Andy
Oohms, what are the stock voltages on your card?
1.3v gpu / 2.08v ramQuote:

Andy: sorry i didn't used orb before, so its a noob question, but at my testXP lan is disabled, i could only make orb at online?? :rolleyes:
oohms: very powerful mods, thanks for share, if i kill this baby, i will do this on the Gigabyte :lol:
Score update before i go to bed:
25001 -> http://service.futuremark.com/compare?2k1=9328593
woot :D
air cooled, 1.5v gpu, 2.2v ram, 690/1380/540 gpu/shad/ram
http://i30.photobucket.com/albums/c3...wbot/25001.jpg
Does anyone know if it's possible to loosen ram timings on the cards within the BIOS? My ram is limited to sub 880MHz which is really cramping my style.
couldnt you use Nibitor and tweak the timings? :up:Quote:

Achill3uS: What does it say on the 2 chips with 8 legs in this pic:
http://img186.imageshack.us/img186/2866/02le0.jpg
Im running +3.0 LOD with all the tests. Is there any way to get more than that? (im using rivatuner atm)Quote:

LOL
wow man some serious clocks
do some benches heheheh
Running for a contest dinos22, just nature 2001 and at a amd fx55 setup
Don't think its realy interesting for the whole benchmark, i wil try maybe later on a yorkfield.
First '03 run:
9260 -> http://service.futuremark.com/compare?2k3=5716566
e8400 @ 4ghz, card @ 690c/1380s/540m, 1.5v gpu, 2.2v ram, air cooled
only basic LOD tweaks
http://i30.photobucket.com/albums/c3...hwbot/9260.jpg
Ohh, nice challenge, I like it:)
I would be join, please write up for list zakelwe!
over@locker886 added to the front page ..welcome to the comp! :)
oohms new 3dscore added well done ! For Rivatuner LOD the setting to increase LOD range is under POWER USER -> RIVATUNER \ NVIDIA \ GLOBAL -> LOD BIAS RANGE. And set to 15.
Classically nvidia from 6XXX upwards tends to have a spike at about 3.3 in nature, but I found 3.6 good for nature with these cards, feel free to experiment.
Rol-CO and the other dutch guys have been doing some fantastic hardware overclocking and software tweaking for their competition. :toast:
Regards
Andy
So you are limiting the compeition to people who have Pro accounts?Quote:

HAHA loving that water cooled power circuit!Quote:

That's why i build this up with the original cooler of the gs,so switching to watercooling was easy and planned, burned my fingers already with the test setup.
so fets has to be cooled, one of them had bad contact and was getting 120 degrees C at 2.00v running 3d and burned the as5 that was on it.
now they are a nice 35 degrees load at 2.60v at the core.
bad contact :(

Thanks Andy! I think my race card will have Gigabyte 8400GS!;)Quote:

I't been a long time since I was not a pro user and thought you could have one published score per 3dmark, if it is only one on the ORB then as long as I see it up there and you get your score on the first page leaderboard then you can then take it off and do the other 3dmark or any other score you wish.
Would that be workable for you T_M and others?

Andy
sounds fine to me.

thanks for trying to help me guys :toast:
Both not for the core voltage i think, 1 is the multiplexer and other a eprom (bios) chip.
and the 2 8leg chips on the front?
Interesting stuff, must be a high current draw, if you're sharing the load over 4 MOSFETs and there still getting that hot :confused:Quote:

Yep, you remember the ocz ddr booster...this is basically the same design, and those where getting hot too, just added a opamp to it.Quote:

Sart of a new week, and i have a bit of spare time to finally pick the card. examined the PNY ones at work, and don't look like there upto much at all, so dumping that idea;)
Looking about online at multiple different makes available in the uk, i think i have boiled it down to one of 2 options. 1 is the Zotac high profile one that someone already has on here in this contest. The other i have not seen. Be nice to see what you guys think of the layout and the pwm area. Does look to bad for me, but im no expert:p:
http://www.leadtek.com/eng/3d_graphi...0gse_tdh_2.jpg
The layout looks different to me from the basic design. Also the actuall looks like it may been push further back on the card, cause the cooler is further back, and the pwm area looks to take more PCB space.
Well anyway, i gota get a card here fast to join in! I feel left out at the moment! :rolleyes:

Hi Paul,Quote:

Regards
Andy
I'd say the fastest memory would be the best pick. That is the one thing I wish my card had, better clocking memory as every MHz in memory is like 20MHz on GPU. Fighting for memory bandwidth is interesting to say the least :)
well i had the same idea with the memory, and the leadtek starts with a 500mhz core and 500(1000) memory. couple of websites say it is 2ns memory as well, although no one mentions the brand of it...
anyways, full height card wuld help on after market cooling, but i am planning to try and fit a old skt 939 aluminium cooler on it, so think i could manage that on the half height as well. i think i will grab the leadtek. Then we have another manufacture and design in there.:up:
- Paul
The ones at work (the extreme edition ones) have 2.0ns quimonda ram... im tempted to buy one of those as well :DQuote:

Picked up my Asus today, Quimonda 2.5ns on it...
Welcome \/ENDE][A :)
I bench more this weekend. I'll try some LOD runs and other texture reduction at stock speeds as my othe score to get a feel for percentage gain from these.
Regards
Andy
*sigh* Amazon is taking its sweet ass time to get my card to me, was supposed to be here by now :(
Damn, gonna pick mine op tommorow, hope they clock allright.Quote:

Downloading latest version of gpu-z now and rivatuner for some overclocking on stock air :D
lol only two results so far
i ended up asking oohms to get me a Gigabyte and mod it afterall
waits for oohms to send it over :D :hammer: :hammer: :hammer: :hammer: :hammer: :hehe:
Well i am ordering mine tomorrow.
Leadtek 8400GS 256MB TDH Extreme
probably gona need some help with the vmods on that. Expect stock results by end of the week. possibly light overclock results as well.
Will ask about mods when i get the thing here, and take pics. Is everybody else waiting for theres to arrive?
Heres to hoping it has 2ns memory :toast:
Just a heads up for you guys, i got another gigabyte 8400GS with hynix (for dinos) which only gets 480 ram, so they don't all clock the same :(
(dw dinos ill get a better one :D )
You can put my name down, I'll play!!
:eek: pulls out the black(errr good) book on oohms :shakes: hehQuote:

i should be able to have a 600*9.5 LN2 bench as well from my latest chip
we'll see if DDR3 and high FSB do anything hehehehe
My god, thats some bad ram :( Damnit chose the wrong card then, well I am gonna bench it anyways :)Quote:

Your ram clocked just like my ram but I've got 2.5ns Samsung DDR2 here. With my ram increasing vdimm from 2.08v to 2.31v did absolutely nothing, still walls/artifacts at 432MHz. Tomorrow or the day after I'm going to try nibitor and see if I can manually loosen the timings, otherwise my 900MHz core is useless :(
Welcome Deanzo :up: and nice work to go second staight away.
I've updated the front page, thanks everyone for putting details of timings etc up, it makes editing easier. Note that I am cutting and pasting and so might make mistakes ( especially after a few ;) ), so if anyone spots bloopers please post so I can change.
Also note that I have only included 5 in the leaderboard currently to avoild me spending hours all day updating it, but I intend to try and stretch it out to top 10, maybe I will just put top scores of people below that, depending on how much time I have. I might split it further to split AIR COOLED from ANYTHING GOES as well depending on how many Anything goes we have.
Finally, this competition allows you buying another card if yours blows or the card really sucks of course so feel free to do that if you have a howler on your hands. That's a great advantage of these little ones.....

Andy

Hey guys my card arrived today and disappointingly its Qimonda memory so I'm pretty pessimistic on its headroom :(
It's a Leadtek card and the main GPU controller is the RT9259A, VGPU mod isn't difficult and there is the option of controlling the current limit too which may be useful. I'll know more when I get back home tonite and give it a good look over.
Hey Guys, Benching mine right now, 670/1380/452mhz I would like to know how I get a higher Bar on the Shader, its maxed in the rivatuner control, and i think it has a great impact in the score :) so please help me raising the bar in rivatuner.

Rivatuner doesnt even show a shader bar for me, just core....
I've seen this with earlier version of the drivers with my 8800U so you might try a later nvidia driver if you are using the latest Rivatuner.Quote:

Thats about max it does, hmm some know how to vmod this Asus card?
/Grau
going from 1380 to 1700mhz in shader clock gave me about 300points in 3dmark03.
We need to compare memory timings I think, how do we do that?

Hey mate, that's the best step by step Vmod guide i've seen ever! :ROTF:
Hmm zakelwe, nice one :) but seriously, iam quite a noob on vmods, so need this card to be the starting card in my vmod experience, :)

When you have the leg to solder to then it's 20x the measured resistance to ground and then work downwards. That's the fools guide that I have been using for the last 5 years.
Now as for the Vmem mod for the Leadtek I hope Mr J.Guru will be as kind to me :D Coz I can't work it out ;) Probably one of the 3 leg regulators on the board somewhere .....

I ordered my Leadtek 8400 GS TDH Extreme. What leadtek card is it you got Johnny, and what ns rating are the memory modules?
I doubt now mine will turn up tomorrow, but friday it is all go from me.

Damn my 7900GTO just died on me, hmm have RMA it, so have to use this 8400GS until I get the GTO back, Hope it does not take that long.

Hey Andy, I read your vmod guide, really great! Can you tell me what I must do differently on an EVGA? :D:D:D
With those you are best reversing the polarity.Quote:

Hey now, I like my little EVGA 8400GS :D She might not have the beefy PWM of the Asus but so far it's been good to 900MHz at 1.74vgpu :cool: Later today I'm going to toss 2.0v at it and see how it scales. Now if only the DDR2 didn't suck huge uhh soccer balls.Quote:
