Gainward GLH 9800GT 512MB
 

Voltage of the GPU

Standard voltage = 1.13v
OVP = 1.13v + 180mV = 1.31v (seems to be rather 1.3v + 180mV = 1.48v)
Pin19 = FB, 100k resistor between pin and ground



Voltage of the MEMORY

Standard voltage = 2.10v
Max voltage = 2.45v



Measurement points

Blue = Vgpu
Green = Vmem

Let's hope for +800GPU /+2000 Shaders action :)

Doing a quick test with the first card at 1.265v Vgpu. 800/2000/1200 is GT4/03 stable, without artifacts.

830gpu, 2100sha is no-go

Increased voltage to 1.35v to see effect on overclockability and temperature.

850c = no-go; 830 is stable
2100s = artifacts/lock-ups; 2000s is just fine
1200m = still okay

Not worth to increase voltage that much. If I were you, I'd stick to 1.265v and freqs of 800/2000/1300, which is perfectly stable.

lower temperatures will probably help more

maybe 830/2000 shaders ? and rams at 1200Mhz, is that posible at 1.26 ?

1.22v GPU

Cannot show cpu

what are stock speeds of this sample?


rub it in! will ya

650GPU, 1625 Shaders en 1100mhz rams John

Massman already replied to that Albrecht

Ik heb ze speciaal gekocht omdat er speciale rams op zitten, normaal ist maar 900mhz rams , deze zijn stock 1100mhz (met ruimte :p)

Second card is SLIghtly better; for dual card setup we need to downclock.

at what speed is that MM :).

Not that high

Thx for testing Massie, hope to get some good scores with them cards, hoping the OCZ Blades are still okayish

P55-bordje? :)

nope, look closer

:naughty:

Okay, last reference benchmark for ye olde JR

Thx for the hard work, I will do better for sure :p with my 6ghz 720BE

World record #1

Da's dan toch met een ander moederbord dan op die foto's hierboven?

810 GPU :p, goe gewerkt

Ja, met dat ander moederbord mag ik niks posten

Hi, nice VRAM on that 9800GT.
What about some more voltages with better VGA coolers?


Btw, I just realize that those cards supports triple SLi :)

More volts don't really help in this case: going up from 1.265v to 1.35v gains me 30MHz on the core and nothing on the shaders. Lower temperatures are the way to go, I think.

The PCB is the one of a GTX I presume. Nvidia never supported 3-way sli for the GT cards, so even if I connect a third card, it's most likely there's a problem with the drivers.

I have several VGA coolers here, will see, once I fetch the cards... so we need to get them sub 60°C to get more out of them (since they still top at 60-65°C with the boxed cooler)

Do you have a watercooling setup?

I have a watercooling setup but no blocks for them cards... Been looking for some Swiftech MC60-R but can't find them at a decent price (there's one that has 2 MC60's but they are not cmpaible to all Nvidia, ATI cards...) for single vga we can mod a mount of a normal CPU block ( I see the XSPC is the same for the GPU as the CPU ), for SLI I would need them Swiftechs... or sortlike...

New blocks would cost around 45 euro's a piece, without shipping fees...

First up: more cooling on the CPU. Too bad I still haven't made a couple of LGA1366 mounting holes for my Mach2 unit ...

this makes me absolutely sick !

Massman you are aware that if ya HD's are full of Data that they weigh at least 100grams more ?

The more the merrier.

Currently running 4.5G 3D stable ... cool!

I had several G92 cards(88GS/GT/GTS) and they always scaled good with more voltage on air. Even with 1.4V+ and an ACS1 on it.

Yeah, it seems to be scaling so incredibly bad ... weird.

Anyhow, here's world record #2

I'll be back !!! top job :)
