V4 4500 183MHz BIOS - testers wanted

[-HoNY-]

Hi visitor, I have created a 183MHz BIOS for v4 and I'm looking for testers.
Its based on v1.15 and it changes the dram latency from 2-2-2-6 to 2-2-3-6.

Files and documents are available here: http://download.pc-centrum.net/V4_BIOS_rev.3.zip

mod edit: grammar

FOR TESTERS please write here:
1)Stable on my card YES/NO
2)Performace before/after
3)Tempeature
4)Brand of memory

5) (optional) what you mean about my anty-nVidiot logo

sorry for my gramar

[I.C.]

I have two spare boards and will try each, AGP right?

Yes its AGP bios.

Whats BRAND of memory on card?

[I.C.]

One Toshiba, the other Hyundai

[I.C.]

Both 4500's have been flashed and are running Quake 3 demoloops at 183 mhz.

3DMark2000 fill rate MTexel/s before : 271/323
3DMark2000 fill rate MTexel/s after: 290/355

Quake 3 before: 32.0
Quake 3 after: 35.2

1024 x 768 x 16bit x 2x AA, demo 001.

The back of the GPU is very warm under full load, 141-145F.

I will check later today what the temp is at default clock of 166.

@ -HoNY-
Some people try to modify a V4 4500 32 mb into 64 mb (an old dream now) ; i have No idea if they can or will succeed but the current bios will be perhaps a "botleneck".
What do you think about that ?

[ps47]

..you mean that voodoo4 4500agp 64mb that was created by DenisF? I think he created his own bios (so the card was able to "see" the additional memory),are you suggesting HoNY should mod that bios as well?

[I.C.]

so the card was able to "see" the additional memory

Jindra Semenec states it is not a bios issue but a hardware one.

Bios changes will make no difference, the card still will not access the extra ram.

[ps47]

..according to this,the v4 4500agp 64mb mod is complete and fully working..

[I.C.]

And what proof does this individual offer? A picture that can be done in Photoshop?

"no amount of bios mods will let the board see the extra ram modules"

You can put your trust in Jindra Semenec, patron saint of VSA-100 or a 17 year old who posts on web forums.

I thought indeed about this V4 4500 but also a topic on VoodooAlert.de.
According that, you would need a (new) resistor on the pcb in order that the board utilizes the new ram.
But probably you would need then to modify the bios.

i wanted ram for this mod (5 or 5,5ns SDRAM) is better for agresive latency my dream is V4 4500 64MB @183 2-2-2-6

Nice but only helps one side of GPU

I have mod for cooling backside, will post picture soon.

Jindra Semenec states PCB of card dissipates up to 50% of heat generated.

my card is cold cca 35°C = ???F

[no-X]

T(F) = 1,8 × T(C) + 32

140 degree Fahrenheit = 60 degree Celsius

What is the reading on the backside of the card where the GPU pad is located? And what are you using to test?

I have used digital probes from Radio Shack but have just started using infrared meter.

My hand is qualyty tempeature-metr on backside where is GPU
I using FAN on cooper heatsinks therefore is too small tempeature

Thanks for posting picture!

20F-25F temp drop at rear center of GPU when fan is running while under maximum load.

nice one
