350/1000 10916
425/1.1= 12440
450/1.1= 8983

what the crap! im watercooling the gpu core temp never went 43C. has anyone one else run into this??

i havent had an nviida card since my ti4400 whats the dealio??
 
All cards have optimum performance clocks.... ive overclocked my 5200 to get lets say a 1300 in 3dmark 03, but if i oc it too much... ill get a 900 or less..... if u underclock, you klose points, if you overclock too high, you lose points...
 
Perhaps the card is automatically downclocking due to not having enough power?

If you watch the benchmark run, you'll likely see a pause or two, on your 450/1.1 run this is whats causing the slow bench and is usually caused by clocking the GPU core too high.
 
getting the gt instead of the ultra i was thinking the other power plug might be a draw back,
but im using an enermax470, enermax have a seperate 12v line that is designed just for video cards also they have 2 sep 12v rails one for mobo 1 and 1 for case acc. i was hoping that would be enough.

i never like to pay for the top end card cuz i like to upgrade every summer and replacing a 400$ is easier to swallow plus i always o/c well past the top model anyway which is why im sorta perturbed by this situation

the core is cool to the touch even@ 425. hhmm to bad i can tell their is still plenty of headroom left in this core,

hhmm maybe if i bios flash to the 6800ultra itll up the voltages and let me get me more headroom
 
You upgrade every summer, so $400 is easier to stomach?

Do you have a 9800 Pro I could buy for $100 since you won't be needing it now? :cool:

Seriously, do you sell the old ones, or do you have a hand-me-down system among multiple rigs in your house?

It is not your power supply that is causing the issue, it is that one bloody molex!

a little of all 3 between wifes computer, my best friend whos been short on upgrade funds lately, and work people in need of upgrades.

i try real hard to keep my computer stuff to less then 1200 a year total. plus i can easily sell my old stuff for about 1/3 of original cost, so it works out to be not much for a top of the line computer system year after year. i buy ram and ps and cases as rarely as possible.

but yea after some more tests i really do think its that 1 molex connector thats where im falling short. their are the solder points for the 2nd plug so next spring when a 6800@430/1.7 actually starts not being enough horspower then ill wire that bitch up.

i sat through 3dmark and yea it kinda pauses/hanges for a couple seconds sparatically, but hey that may sound like a bad thing but during this last round i thought of something funny. "soy hotpockets" for the socialist hippie on the go.

so i think im gonna try flashing it with the ultra bios. seen any threads on it? thanks again for your input guys. living in alaska the online community is the only help i ever get

Wiring it up won't help, on the other side of the molex on the graphic card PCB you also needed to double the number of isolators/regulators.

I believe that when you overclock too high, the video card starts messing up, causing you to loose frames, cauing Score to go down
 
yea what perplexes me is how the 3dmark just hangs for 2-3 seconds then just keeps right on going, i have never ever been o/cing and had it do anything beside artifact, freeze, or crash to desktop,, but i cant get it to do any of those 3 things

do you guys think that upping the agp voltage could help with the overclock? this seem card just seems to love the juice
 
I need to correct you on the enermax dual rails. The ATX version 1.2 and 1.3 reference PSU units from enermax have dual +12v rails for the motherboards for P4's, not for video cards, your information is horribly wrong.

One of the +12v rails goes into the motherboard, supplying the motherboard directly through the ATX connector.

The other +12v rail goes into the motherboard VIA the 4 pin conectors that supplies the processor with it's own independant rail.

The system shares power with rail 1, which powers ram, chipset, I/O, etc.

The hanging sounds like the card is automatically downclocking due to a lack of power.

from the manual
"seperate 12v rails supply to mb/cpu and drives in order to provide stable and clean current to noise-sensitive devices such as cpu, add on cards."

plus they have the lone "extra" plug designed mainly for vid cards. i havent opend it up yet (ive voided enough warrenties watercooling) but its to bad its not part of that seperate rail with these 6800elec whores that would have been very nice.

it occurs to me however for o/cing say a prescott it would make sense to need to focus so much juice on mobo/cpu. i was deducing it from the amd/nvidia standpoint where cpu and vid card are the main consumers of the 12v rail

thank you for explaining. I see now where i was shortsighted in my thinking.
