All I did was take the stock BIOS and edit it with NibiTor to give me 1.4v... it's nothing special...Quote:

Perhaps, but 4 hours of gaming without instability or crashing is enough to convince me that any errors that might be there are insignificant enough.Quote:

Im just trying to explain why some people cant overclock with Rivatuner after they enable the extra quad/vertex. Allthough some chips are 100% working and just maybe not so tolerant to high frequency, a lot have defects (some of which dont manifest themselves as visible artifacts) which cause the internal clock test to fail. Its not just reporting error to tease you. Ofcourse as you said, sometimes the defects are so minor that they dont make differences in games. :fact:Quote:

Noticed that Don's BIOS are an moded standard 6800 instead of LE, I was affraid to tried them and killing my card, instead I kept my BIOS settings as they are(405/902/1.4V).Quote:

As don_vercetti & total_assault pointed out that my '01/'03 scores are perfectly fine, and I rather have an stable 24/7 system so I decided no to push it too far.
405/902 = 4805... you are definetly in the right range.
3DMark2005 has relatively high affinity for video ram... that is, unlike most games, your score would have gone up even at 1024x768, if you had more video ram. It also scales with video memory speed, memory speed, as well with cpu speed. Ofcourse biggest difference is GPU speed... check here:

I have been addicted as hell to kotor II played almost 12 hours straight... no problems with stuttering or performance issues, no artifacts and very stable... once in a while the game will boot me off to the desktop, as with republic commando... but this is because Installed the game with my backup discs instead of the original, I backed down the card to stock values and it still happens...
so this tells me my Overclock is rock solid..
maybe the internal clock test really does detect errors.... but if the errors are so insignificant that it can't produce visual or performance errors and is rock solid stable.... then who cares?
I think Riva Tuner is probably doing it's job, but the bottom line is real world results with stability, performance, gaming and benching.... in that order :D
Hello,
I received my Leadtek 6800LE about 3 days ago, the card is really amazing, it's big and heavy.
I have unlocked it to 16 pipelines and 6 vertex shaders without problems (no artifacts), but like some of you when i try to overclock it in rivatuner even 1mhz it says that the driver failed to pass the internal clock test, i don't know if this also happens at 8 pipelines and 4 vertex shaders. Should i worry about this?!
Thanks ;)
Some people can't even pass the test 1MHz below stock without unlocking. I'd just use a looping 3dmark and the eyeball to detect instability and artifacts.
First of all could you take the time to spell check/proof read especially when your asking for help, we don't speak gibberish here, are trying to flash the video card or the motherboard?Quote:

by all means, but I think I posted some really good overclocking tip in "6800nu scaling" thread, like check that 3DMark2005 or whatever benchmark you're using is actually going up as you raise the clocks... Because, although you'll certainly never notice with your eyes, at a certain point, scores go down 500-700 3DMarks.. and if you increase the speeds even further, the score drops catastrophically as the test locks-up... well that is my experience anyway. By the time I get to see artifacts, I back down to 3xxx from around 5000.
Case example:
I have hynix 2.8ns chips on my xfx 6800. With stock bios timings I was limited to ~790 (internal clock test) and ~910 (disabled). After altering video card bios with more suitable timings, I get to ~790(internal clock test), but ~1010 (disabled). All of these settings 0% artifacts rthdribl through inspection, as well as running ATITool tester. Great, you might think... 1000... but in reality, all is not well. First, the score in Aquamark3, Quake3, 3DMark2005, etc actually goes down (when used in conjuctin with 325gpu... and secondly, you cant clock the gpu high because then it really locks up an even causes computer to freeze (unresponsive). Its a matter of tradeoff. 970 worked in some benchmarks, but only ~945 in 3DMark2005.
But, dont be disappointed 6800LE/6800NU... in shader instensive games, with very high polygon count (>1M per scene), like 3DMark2005, I have shown in 6800nu scaling article that extra memory bandwidth doesnt improve score much... better to try to get higher gpu speed... (one that gets you higher score ofcourse)
is this deal still available?
yes, go to newegg.com, go to video cards and search 6800le it is $124-129 now, refurbished its $114.
ps: i couldnt check today this is from a couple days ago, newegg is doing some server maintaince.
Leadtek 6800le = $100 refurbished ... $124 new.Quote:

my first tests with 6800LE

with more clock a I can beat 5k no 2005.. I hope haha
For your system 2Ghz Sempron with 350/900 16/6... that is VERY good score of 4500+... how did you do it? Did you use performance profile in driver? Change LOD? What??Quote:

fast wright on and 77.77 driver, original ram timmings and vgpu 1.4v (moded bios).
http://service.futuremark.com/compare?3dm05=1247187
I will try 350/900 with high performance...for comparison, I am using 71.89 driver, fastwrites off, and custom timings on the GDDR.
EDIT: 4526 3DMark05
GT1 - 18.7
GT2 - 13.7
GT3 - 23.3
Incoming n00b question.
How do you pull off the default cooler on these cards? I managed to remove the flyscreen/filter and its surround, and I've located the two plastic pinch clips at the outside edge of the cooler, but the front and back still seem to be bolted together when I undo these. I noticed there are funny looking spring loaded clips with unconventional fasteners around what must be the core - would I have to undo these somehow?
I feel so lame, I can't even get the plastic shroud off.... :(
I'm not pulling mine apart again to make a pictorial tutorial, but I'll outline the steps.
First thing is to remove the small part of the plastic shroud on the back side. It's held by two small screw.
Then you remove the back plate. They are held on by the four metal things (springloaded). If you have a screwdriver that can fit, then just unscrew them. MY flat heads weren't the right size so I unscrewed them using a staple remover XD. They're springloaded so be careful.
There are also plastic holders that are holding the back plate. Just pinch the tips and slide it through. The back should now pull right off.
Now you pinch the plastic tips again and push it through the PCB. The front plate (along with the front part of the shroud) should pull right off now too (a bit sticky because of the thermal goop).
Finally, there are about 4 small screws holding the shroud to the front plate. You can just unscrew that.
A belated thank you ChronoReverse. Following your instructions, I've managed to pull mine apart to basically satisfy my curiousity (eg. find out what mem chips are used), and apply AS5 for a final weekend's run on air before going water - and took pictures along the way, which I'll share with anyone interested.
Bare card with HSF pulled off - it is SO much lighter with those two copper slabs gone! Thermal paste as shipped: white stuff on RAM, greyish kinda pad material on the core.

Here's the underside of the HSF, showing T&T 0.25A fan, and raised blocks for the RAM.

HSF with plastic shroud removed.

RAM on my card: Hynix chips. F-28 I assume means 2.8ns, theoretically only good for 715Mhz. Which is surprising that I've managed to 'clock mine at 930Mhz with no hardware Vmods.
http://kayimages.com/images/a400c.jpg
The back copper bit is purely for show. As people have mentioned previously in this thread and elsewhere, there are no RAM chips and no real reason to be cooling the back of the core.
http://kayimages.com/images/a400e.jpg
The white rectangular blocks aren't thermal pads, but spongey/foam bits I guess to ensure the correct spacing for contact for the front block- since the vid card is sandwiched between the front and back copper slabs, and these sponge bit plus the spring loaded screws could prevent overtightening.
nice card for the money..
im gaming @ 12x6 400/900
did the hard volt mods, cap mods and the most that helped was the core/mem cap mods, the noises from the card are now gone, cause before it did worse than a squeaky door hinge.
Thanx for posting Onyx_6800LE. :cool:
