2008 XS Cheapazchips 3D challenge

[ownage]

Come on guys, i haven't seen anything xtreme yet with those 8400GS's on XS.

[Rol-Co]

i think the main reason we are all running air is because we haven't got a high heat load to get rid off. We are all happily going up and up. this little lump of alumium s hitting 65-70c with 1.72v going through the core t load. If i need it cooler, increase the fan size from 4 to 8cm. There just too easy to keep under control when it comes to heat.

Mind you, what are they like going sub zero? do they have any major cold bug issues?

- Paul

No coldbug at the xfx card, some report sort of coldbug at -70 but not sure.

When you running 1000+ core and 2500+ shader at 2.5v you need more than just a bigger fan but you're right about the memory doing the most fps gain.
seen some running 2900 shader, and seen some doing 1170 core

I found the 1170/2900 overclock a bit strange. That was done with only 2v on the core, and the nature score was low. I'm not sure if the card really did run on that speed.

not realy , they where just starting, i know oldscarface can do 1090-2800 with just phase change at 2.3v ......some cards where a lot better. mine was not that good, need a lot of voltage.

[ownage]

Well, mine was really bad. It died with 2.35vgpu watercooled, all FET's cooled with heatsinks and 2 delta's blowing over them.

Dont worry Rol-co I have something to feed your hunger

[hifiking]

To give your cards something to chew on, flash the clocks instead of using rivatuner etc. At least it gives me a healthy boost in Nature.

got my mutant in today

oohms you're a pro man

[GOESA]

What brand is that?

Come on guys, i haven't seen anything xtreme yet with those 8400GS's on XS.

Well I've had 2v on my card with the stock heatsink and mines still going, I believe yours with watercooling is dead??

Come stand for 5 hours at -1C with me and I'll show you extreme, you'd be running in shouting " Mummy my hands are cold" after 20 minutes

If you upgraded that cooler you could bench inside where it's nice and warm Andy...I do

True, however I need to keep my 780i northbridge and all other compentents cool with a 170mm offbard fan. The 780i gets very toasty, even at idle and stock volts the delta from ambient is +30C.

Mine died but not because of the GPU temps. The XFX card is made for 2v max i believe, and i did 2.35v because i had to know if the OCP mod was working. When running 3dmark01 on water for the last time before i would use phase the stupid card died
I put that sucker under phase and it was no problem to keep it subzero

2v is nothing Andy, try 2.3v or higher, if you dare

[T_M]

My XFX GS got the full treatment last night, will post photos tonight to show my overkill.
Basically doubled every capacitor and put some even where there were none, the choke got a buddy, fully vmodded, and prepared it for LN2 pot mounting.

ROFL tim
can't wait to see what you'll do with it

i bought a PCI express raiser extension to mount this little card horizontally with a kingpin dragon evo sitting on top

LOL should be an interesting project hahahah

lol something is wrong with you

[dinos22]

lol something is wrong with you

if successful i'll also try higher end cards too

[oohms]

I realised that i forgot to post my OVP mod for the gigabyte:

(Updated my earlier post)

Tested up to 2.3v (on dinos' card ) but mosfets get pretty hot

[dinos22]

EEK 2.3v lol still alive i hope

i can't help myself

i gotta say i get more excited in preparation stage than actual benching

Gigabyte ready to go

[zakelwe]

At this point Dino realises that his IBM 286 PC only has an ISA slot ...

[dinos22]

checks for ISA>PCIe converter on ebay

[Rol-Co]

Problem of the riser card is you have to twist that 4" cable to put a pot on it, not realy easy i think.

T_M
Watch the temp of those 2 mosfets who are on the left side of the coil, those fellas getting realy hot at high clocks and voltage, some cards died at 2.15v and some not even at 2.6....it's a bit of luck....external psu works a lot better.

[T_M]

Cool thanks for the tip there Rol-co, guess ill sink them with some stupidly oversized copper

Here's my first nights modding effort.
Looking now for any other cap locations i can add heh.
Once its all modded up it'll be completely plastic coated and stuck under LN2

[Rol-Co]

hmm the only 2 caps on the right of the coil might be a little help.....the rest...dunno.

good luck.
