Well, first of all, your card is clocked at 450, not 425, so naturally you have higher scores. You also have much higher clocked memory and CPU, which should mean higher GT1 scores.. but you dont. Did you use LOD tweak, and set driver image setting to "high performance"? Like the description for my project says, I did neither.. exactly as-is when you install driver.. default = quality setting.
Jimmor sent me a few BIOS files, and my problem seems to have lessened. I ran 5+ 3DMark2005 in quick succession at 410/900 without force performance level, and it didn't drop to 3D throttle except in between runs. Chaos theory is the ultimate test, and if it works well there too, then I'll be really happy. BUT, this card is tempermental, and several times I had thought all problems were gone only to return next morning.. I wouldn be surprised if the problem was some cold solder joints.
Run was with lod.. idk I always seemed to have low gt1 and high gt2 gt3, each run. And btw I thought your card was also a le, but it's an 6800 vanilla. Vanilla's always score higher ( well usually ) with identical clocks compared to le's IIRC.
I got caps sikkarippa send me but I got scared off doing the cap mod before I have another good ( read beter ) vc which will be later today or tomorrow :)
If you still have the capacitors, you can send them to me. Or at least let me know which brand, model, and capacitance value.
I tried doing the capacitor mods before, but according to SilkaRippa, the caps I bought are P O S (no surprise considering how cheap they were)
Guys I need help Please!
My BFG 6800 vanilla just died, it worked fine for 2 years...I lapped the heatsink when I first got it, also the screwes from the heatsink show sings of wear(screwing on and off)
So I cant send it in like that...is anyone willing to help me?
Lend me your heatsink or sell it to me if you want, I'll pay for shipping if you want to lend it to me.
thanks a lot

SilkaRippa!
I have a very important question regarding my 6800 problem. Do you know how to increase the frequency of the switching power regulators on a 6800?
EDIT: also, do you get high pitch sound when running coolbits auto-detect. Or in certain games or parts of games? It sounds like its pulsing. So I suspect thats the voltage regulators, with improperly tuned capacitors. If I increase the frequency it shouldn't be audible, and might improve the energy supply from power regulators. What do you think?
@433/936 (using 1.4V in BIOS), driver=high performance, LOD=+1.8Quote:

The LOD and high-performance help the most in GT2. Part of the increase with GT1 is due to higher CPU and RAM speed used for 5505.
Definetly try lower clock speeds, since you might get higher scores. 90% of "artifacts"/errors are invisible. Check in rivatuner hardware monitor that its not throttling.. other than that, its probably just matter of different system config. ex I got BH5 running at 2-2-2-5.
Although I dont think I have the black screen problem described here:
"A very interesting aspect about temperature effect was reported in this same thread (see posts #3, #6, #7, Thank you ZeroHero !). It was found that by cooling the ambient of the card ~ 10 degrees causes immediately BS under suitable conditions. This phenomena can be caused by many factors e.g. cooling of the switching transistors. However, the on-resistance of the transistors reduces when temperature is lower and the operation of the switching power should be better ! On the other hand the ESR-value of the aluminium electrolytic capacitors INCREASES when temperature REDUCES, which LOWERS the performance of the switching power supply (See another document about the aluminium electrolytic capacitors if you are very interested [10].). In order to make this even more complex the higher resistance (ESR) causes higher voltage drop over capacitor and in the same time the power 'burn' in the resistor increases, which increases the temperature (would be nice to make electrical model for this ). "
this would explain why several times on cold mornings, high overclock of GPU and MEM wouldn't work.
***Deimos***, I had a vacation (=no www) for some days, I'll try to figure out your questions...
Cases A-D corresponding your card. I think the most *features* can be explained as too high temperature in certain condition (like in some game test) which causes throttling. I did not get whether there were any differences in the setup except tighter screws ? I mean you get those cases quite random manner (?). Maybe temperature variation gives the random effect, since you said later you had more/different problems in some cases having a cold card.
I read an article about NV5 installation some months ago. There was said that the copper pads for memories and core in the NV5 are NOT allways in the same height. Therefore, NV5 copper pads should be checked beforehand and possibly grind/polish using very fine sand paper etc. If the height difference of the pads is too high, some memories (core) is under higher mechanical stress, which can cause the contact of the BGA ball loosen. Did you have any such problems (cases A-D) before installing/uninstalling NV5 several times ? Do you have any problems with little bit lower Vcore/Vmem ?

About capacitors. 'POS'-capacitors do not help too much, so it is good idea to test with known good capacitor. Unfortunately I do not have any proper replacement capacitors. I had some Chemi-con PXA-series, which have been successfully used by several users. Another good candidate is Sanyo SVP. Those capacitors are hard/impossible to find from 'local electronic shops' , and only solid solutions are 'Digikey' or 'Farnell'.
http://us.digikey.com/scripts/dksear...189480&Site=US
http://uk.farnell.com/jsp/endecaSear...=9188770&N=401
.. drawback is high unit price due to postage & package cost.

About noises. I have briefly considered that issue in the document. There are some explanations and results (ripple current, noisy audio recordnings). In short, noises are due to rapid changes in current consumption of the card (memory& core). These current spikes either 'vibrates' some components in the cards (e.g. coils) or adds noise to normal audio devices (e.g. via molex-connector of the CD-player). The noise vs. switching regultor freuency is complex issue: it COULD have some effect. I suppose the effect is not huge because the frequency of the ripple current (=noise) is in audio band ~ 100 - 10000 Hz and the switching frequency is 300 kHz at stock.
---
About changing switching frequency of the regulator. Yes, that can be altered by a resistor. I considered also to play with that to see effect to BS, but have not (yet) tested. The idea how to alter it can be seen here ('Oscillator, pages #14-15 ):
http://www.intersil.com/data/fn/fn9134.pdf
By adding a resistor between FS_SYNC (pin #13) and GND the frequency can be increased up to 1MHz. However, I have not tested this and suggest to be very carefully. Higher switching frequency does cause extra problems..
Thanks for the link SilkaRippa!
I have switched power supply (again).
even though with this new power supply all the voltages are higher, and thus so should the Vgpu, and Vmem, the problem is just as bad and even worse!! I get even worse artifacts, and it doesnt just pause for a second when throttling but sometimes even a few minutes.Code:410/900 min max
okia 450W
atitool 11.92 11.94 oscilating wave
4.94 4.96 oscilating wave
GT1 11.87 11.91 little impulses
4.98 5.02 little impulses
enermax365W
atitool 12.25 12.27 oscilating waves
5.08 5.1 little impulses
GT1 12.21 12.23 little impulses
5.14 5.16 little impulses
Another interesting discovery:
http://www.xtremesystems.org/forums/...41#post1401141
Where the card throttles (and sometimes artifacts), is also where the "non-local memory usage" as shown in riavtuner has nearly increased to the size of the video memory, or where it quickly drops. This was taken while playing BF2.
Re: Audio. I dont even have a cable plugged into DVD drive.. it happens regardless of how many hard drives are connected. Its hard to pull all the data together because I have over a dozen excel spreadsheets with results. Although when it happens is pretty random, it is rather consistent in which scenes in 3DMark2005 it occurs in (corresponding to drops in Vgpu and Vmem), as well as changes in the game scene (either all memory filled or flushed). I have NF3, and fast writes doesnt work with my card. I get lockups and stuttering even at stock speeds.
I see you have been working & testing in a VERY HARD manner to get problems solved. Quite interesting observations regarding stuttering/memory usage etc. I'll try to get some time later to play with RT myself and test especially those memory usage variations. I have proposed that BS will be appeared just after a rapid memory usage change (=increase).Quote:

The higher 5V/12V voltage levels (within specs) should give better performance at least in respect of 'standard' BS. However, DC voltage of Vcore and Vmem should be exactly the same level set by the regulator as far as PSU is capable to provide enough current (ripple voltages of Vcore&Vmem may vary when using different PSU's)

Stock frequencies etc: Did you have the same (near to) problems when card was new or did you problems started later ?
--
Noisy audio: Is it coming directly from card ?
I'm on backorder for a 7900GT, but for brand model ect sikkarippa posted somewhere which type's where good iirc and you can always ask him. If I decide not to go ahead I will send them to you in the near future when I get my new card.Quote:

If by chance a nVidia driver software developer comes around here...., what by chance causes the driver or the BIOS to trigger changing clocks from 3D perfromance to low-power-3D.. and why would the video card ever throttle down to 2D clocks when running 3d app?
I think that answer would be temperature but I could be wrong ;)
Hey guys been a while scince i started posting on this thread (page 18 and up) just thought i would let you guys know how my cap mod turned out.
I went ahead on the caps i got from sikarippa (a huge thanks to you sir !!)
and soldered them in and have been running the heck out of this card for quite a while now and have been able to do some extreme mem timmings with custom bios's ect, and have gotten no black screen she's running stable at 335 gpu and 905 mem or so, with everything i run, 3d mard 05,games ect..
too bad i cant unlock the last 4 pipes but sure is a big diff with new timmings and 12 pipes instead of the stock shut down version.
Just wanted to say a big thanks to you all that have helped put thier own unique experiences,talents,pictures and info here for us all to do what we love best tweaking and playing games :D. Also I want to express my gratitude to sikarippa for his ongoing fight and hard work into making all our lives a little easier,and helping to give us a little more performance out of our old faithfull 6800 Le's Thanks a million. M.L.Dovell.

SikkaRippa is the man but I'm glad I have the money to upgrade now, allot off very cheap cards available atm which blow any le out off the water ( 7600GT or even GS anyone? ).
I will keep the le though, never know if with a better cpu/ram I could climb a few spots on the orb and it's a fun card to bench with.
Hope my 7900GT will be a good clocker since I enjoy benching more then gaming lol and with my pos cpu/ram I can't do any damage with a full field off players compared with us LE owners :)

that might be wrong as you can cook a card pretty quick if you get it wrong
but I am putting it into my pop's computer maby tonight or in the next few days (he only has an ati 9600-xt) and is looking forward to being able to play his farcry and medal of honor with some decent settings, soon as it's in I will get the timmings along with what else i did to it's bios ( with nvflash) along with a run with 3d mark 05 to see where are two cards sit, his puter is only running an athalon xp 2800+ (not 64) with the older socket A with the 333 mhz Front side bus and 1x pc3200 and 1x pc2700 ram,so if the bench in 3d 05 dosnt come close then i will re-install it in my machine for a few runs to try and show you and me the diff in scores on the mem.
I do know for sure however that my mememory is the same as yours Hynix 2.2ns,but i have the stock cooler, I really have a crazy amount of air being pumped into the case i think it keeps the card cool enough.
M.D.

(6814 3d05 not pushing tooo hard). There's somthing that has me drawn to these little budget 6800's though I like the tinkering and tweaking and trying to make em run better and faster, and if you burn one up heh you learn somthing and you might not cry as hard as they could be replaced in a resonable amount of time on a small budget (like me lol). But please let me know how the 7900 runs when you get it I am very interested in buying one this year and selling off my x800-xt,
I really would like to see some scores on 3d mark 05 along with any other bugs/ feelings you have on it. Take care M.D.
Lol I should have them in sig but there's an easier way, just browse orb for le scores for hwa MtM which is me ;) I'm first page in every 3dmark with 6800le last time I checked so it's easier then letting look up all those compares and post them here :)
05 btw isn't my favourite because I can only get a measly 5430 ;) 03 is much better, and I think I stand allot higher to :)
Edit, pcmark05 6800le I'm not bad either, #3 atm and the two above me are a dual xeon which will kick the ass out off any venice in multithreading and the other says P4 but seeing it's above the dual xeon I recon it's also a dual cpu rig.
Edit: Ok lol I read that back and that what a pretensious litle :banana::banana::banana::banana::banana:!!! ;) So I'll link the compares anyway :)

I certainly hope thats with LOD and high performance in the driver. After about 380-400, my 6800 becomes very bandwidth limited, and thats with memory running at 900, 950, or even 972 (after voltmod). Go figure. With core only at 375, the GT runs memory at 1000, and Ultra with core at 400/425, memory at 1200.Quote:
445/860 and i have 5050-5100 in 3dmark05
for everybody who is only getting 800's with 2.2ns Hynix
get NIBITOR 2.8 from mkvtech
you can test timings in windows without flashing!!
for 900+, I found I MUST have tRCDRD=6 and tRP=6.
Intructions:
1. Tools-Read BIOS- Select Device-OK
2. Tools-Read BIOS- Read into NIBITOR- OK
3. Go to Timings tab, and click autoselect to change to proper timingset- ok
4. click detail timings, and you will see your timings.. make changes as desired. When you click ok, you will notice, that the Timing0, Timing1, Timing3 have changed. Write these down!
5. Back at the Timings tab, Click test timings, get timings, and insert the values you wrote down, click set timings, and go run atitool artifact tester (highly recommended) or some other benchmark.
EX:
Timing0: 060C1512
Timing1: 05010307
Timing2: 00240306
correspnd to:
tRC=18
tRFC=21
tRAS=12
tRP= 6
tRCDRD=6
tRCDWR=3
tRRD=4
no, that's with default settings in driver... i don't know what is lod... hm, i have test this timings and still i can't have 900 without artifacts.... i don't know why?Quote:

Its also a good idea to have at least a large fan blocking at the back where all the chips are in the corner. They get very very hot.
