Have you checked the ram? If its Samsung BJ11 its 1.1 and I know early Connect3d X1900XT's did ship with 1.1, you've already mentioned that you dont run any cooling on them hence why u may not be able to push as far as you could.

iv got 1.2ns ram on my card. and theoretical max for that is 833.3mhz so it makes sense that they would be running into the red zone beyond that speed.
 
looks like the extra 100mhc overclock i got out of my cpu is paying off. i now broke the 5k mark in 3dm06 and my 05 score was better too by over 60 points.

what would i get if i had a dual core cpu? in 3dm06?
 
Just had a quick go at clocking my Connect3D X1900XT 256mb, put it to XT-X clocks. Seems to be hitting 55°C atm tho :confused:

Not sure if that's good or bad :) I set the fan up to custom tho as it didn't seem to run the fan up very much at all on defaults.

those are very low temps there :eek:
 
It's under water ;) Mav your 06 score looks a bit low on your earlier post,sure it should be a bit higher than that mate

Sure i used to get around 5500@ stock with my opty@3Ghz

my operating system is x64. and my 06 score is nearly the same as it was on my overclocked 7900gs 256mb. nvidia x64 drivers far better than ati's.

hope ati sort out thier x64 driver support and improve its performance.

ok here is my 3dm05 score. guess i need more cpu power.

iv put the vf-900cu cooler on the card now. max load temps in articaft tester go up to 68c. zalman is spinning at full speed.

core 625mhz @ 1.300v
ram is at 850mhz stock volts.

also note that the ram chips are running bare. thats right they have no cooling whatso ever on them other than the hot air blowing over them from the vf900cu. after major 3dm05 loops and rthdribl running for ages i touch the ram modules and they are barely warm. looks like the stock cooler is a big negative since it just dumps its heat into the ram modules.

reason i got no sinks on the ram is because i put the ones that came with the vf900cu on my 7600gt. and too risky to remove them when i sold the card so just let them go.
will grab some thermaltake copper ramsinks tomorrow and slap them on next time i open the case up.
shocked the ram has gone so high, its just samsung 1.2ns stuff. could try to go higher on the ram at some other point but looks like the returns in performance is diminishing.
need better cooling on the gpu core, then will try and go higher on it at some point.

So unless Im mistaken u have a 3Ghz opteron single core, running an x1900xt at above stock and get 10k+. Check my sig I have a 2.7Ghz single core opteron, x1900xt @ stock; and get 11k+. :p

Oh and xp32 vs your xp64bit.

yep, 64 bit for ati is a performance penalty. also that score for 05 was with the cpu at 2.9ghz.

under xp32 i should be closer to the 12k mark according to other similar projects on futuremark.
 
Here's my GTs:

Make: His IceQ
Model: X1900GT
Core Speed - Voltage: 700 - 1.450V
Mem Speed - Voltages: 800 - Stock (2.086v?)
Memory: Samsung 1.4ns
Load temps: About 83/91 (GPU/VR)

Make: Connect3D
Model: X1900GT
Core Speed - Voltage: 625 - 1.40V
Mem Speed - Voltages: 700 - Stock (2.086v?)
Memory: Samsung 1.2ns
Load temps: About 78/86 (GPU/VR)

My Connect3D Card will go further, just that single slot cooler is not a patch on HIS card.

It looks like artifacts,have you tried dropping your card clocks back down a bit ?

Well, its my memory wall, infact I have a wall at everything now :rolleyes:

716mhz on the core at 1.45V is all it will do, 1.475+V doesn't give me anything more, even 1.5V @ 720 = crash.

846 on memory at 2.45V (low level so timings are tight) or 2.115V (driver level - loosened timings) trying anything over that results as in that screenshot.

This XTX must be able to do more... :/
