2008 XS Cheapazchips 3D challenge

[Kaffebord]

I knew I would create some rules and then halfway through the comp somone would try to bend them completely. I guess it wouldn't be XS if that didn't happen

Considering we have cards wired into Frankenstein at the moment I doubt your water block will create too much of a tidal wave. So give it a bash and good luck.

Thanks mate!

[GOESA]

Here are some voltmodded results,

quite dissapointed, gonna work on them som more, but don't I can get much more out of it.

edited my last post with new 03 score, which gives me the 3rd place in 3dmark03

And please remove deanos 2nd score from the 03 toplist

testing at the moment........435mhz was max without cooling

so far i can run the mem at 465mhz, chilling the ram gave me at least 30mhz

evap temp -> -48°C
watertemp -> -4°C

[G.Foyle]

Well, now how to make a dice pot for memory? I have to figure it out quick

[G H Z]

What kind of ram is that jan? Like that setup!

[Rol-Co]

jan ......great !!!!!! put 2.08v-2.12v on it , the colder you get ..

[STEvil]

GOESA - Our Dragothic High scores are identical, LOL!

Feed the mem more volts, yours are are way better than mine. 2.2v was my limit, anything more didnt help at all.

[GOESA]

STEvil, my mem artifacts in windows at above 2v så thats just bah

GOESA scores added, spotted I had not added Jan's.

If anyone can see their score up there on the first page let me know.

Just out of interest am I the only person whos card does not work with atitool or is this a 8400GS thing?

[SpikeP]

Yo johnny. I have the same issue. I just use Rivatuner for my overclocking, and monitor the clocks on it as well. Gona be putting the card back in again today for another go. need to check ORB though as well. What kind of gain do you reckon i would get going from vista to XP?

Need to work on the memory today

vdata is printed on the chips

hm, setup is a bit messy

jan ......great !!!!!! put 2.08v-2.12v on it , the colder you get ..

465mhz with 2,06v is the maximum i can get out of the ram increasing volts any further did not help

[STEvil]

I only use ATi Tool for mem testing.... got up to 486mhz @ 2.48v yesterday.... then the mod FELL OFF for some reason.. will take a closer look later.

My water cooling setup is almost done, just a bunch of welding to do and holes to cut.......

[masterpain]

i ran my first tests a few days ago. my card (xfx) is the sme like jans.
i have the same problems with ramspeed, my card did 450 mhz out of the box, vmem to 2,03v (lokks like the sweetspot) brought me another 15 mhz.
max core is around 860mhz, but there is still some testing to do and no time atm
maybe i have the chance to put my card on jans setup.

[Rol-Co]

The dutch contest has ended and this was the best i could do with nature.



next contest is a xfx 8800GT

[dinos22]

ok so now we know rolco's got at least another ~10% speed backup until a few final days of submissions

me still waiting for z card lol

[STEvil]

I think the memory VREGs are too weak to handle the current draw and that is causing our "limit" for a lot of the cards.

I suspect my mod fell off because the transistor got hot enough to desolder it....

[Rol-Co]

Memory vregs is not the problem i think, that one is not realy high curent.

The core is though, my 1kw psu shutting down on me ...card is at the 30A 5v line but that one is not sufficient.

Maybe cooling down with fans is a solution stevil, if you think thats the problem, cooling youre fets is always a good idea, they burn literly of the cards overhere.

[STEvil]

The mosfets controlling vcore are quite cool on my card but the mosfet which provides memory voltage will burn my finger...

[zakelwe]

And people said 1KW PSu's were overkill, they obviously never had to deal with the power requirements of the mighty 8400GS.

It'd ue to be -2C tonight so I am going to try for 900Mhz at 2V on the stock cooler. Bit of a suicide run probably. With ambient below zero and 200cfm fan blowing over it heat on the mosfets etc is not an issue, the issue is that my qimonda memory seems to be deteriating over time, originally it could do 575 but now am down to 550-565. That negates the gpu increase of course so it is a bit like treading water.

[Rol-Co]

Mighty 8400gs
Mybe the new psu's are not designed to get high current on the 5v line, or i should have taken the 12v 620w enermax Liberty was running easy with no problems

running at 550 memory ....omg i would do a kill for that speed.

[G H Z]

550 memory is lookin good to me considering this EVGA I've got here. Core/shader clocks are decent @ 1.7V but I'm going nowhere fast @ these memory clocks.

[Rol-Co]

Already tried to flash another bios version GHZ ? , maybe the one from the xfx

[G H Z]

No I ordered a Zotac instead
