84.21 gave me a lower score. It gave me 8.9k with 580/1830 and X2 3800+ 2.6.
This is my 24/7 settings...quite a nice sore i think:)
Which drivers are you using vocch, I only get 10696 shown below using 84.21 :confused: :(Quote:

That is a sad score compared to mine at lower clocks......what drivers...now that would be telling:) ....nah let us know how they do for you.
MSI NX7900GT 84.26
Edit: Just noticed they are the original drivers for your card.
A quick search on the orb of the highest 7900GT scores with FM approved WHQL drivers shows every score on the first page with 84.21 drivers, including mine :) I went through the first 4 pages and they were all 84.21 drivers. Maybe that is the highest driver that is WHQL and FM approved, I dunno.Quote:

The delta thing will not hurt your card. Its kinda complicated, and I don't get it all, so I can't explain it that well. But there is more than 1 core clock speed on your card. When you adjust the core clock, the others are automaticly adjusted to match. You can see all these clocks if you use rivatuner with the 7800 cards, of course this doesn't work for the 7900 cards yet.
The geometric delta clock adds a certain speed to one of the clocks. So if you set a 40mhz delta in the bios and set your core clock to 600 with coolbits, your core is actually running at 640mhz, which is 600+40.
What I usually do is set the delta to 0 and overclock the card as far as I can. Then I start adding delta in small increments to see how high I can get it. With my 7900GT it was 724mhz plus 40mhz delta.
Hope that helps, but like I said, I don't fully understand it all myself. Maybe someone else with better understanding can explain it better.

Thank you for taking time to help me:) But where du I find delta in bios?Quote:

Sorry of-topic, but is there any lower vmod then the 1.4v?
Yes there is u can add voltage in 0.5V increasments...
Check it out in xtreme graphics mods section ;)
I can't find 0.5vmod, only 1.3/1.4/1.5v. But do the stockcooler handle 1.3v?
http://img401.imageshack.us/img401/6861/mod7by.jpg
SO I gather to hit 11K in 05 is a big deal, is that just on the vga OC, or including OCing the CPU?
I should be able to get damn close of not hit 11k with my 148/evga 7900GTX with the 1.5Vmod?
Assuming I can get a stable 2.9 oc, as I did hit 2.9 before, just didn't work on getting it stable. and that was on air cooling, after I get the wated installed........if ever i do.....then if the Mod/OC gods love me I will get a decent oc out of my beast.

Well for a standard 7900gt yes....but for your evga 7900GTX No....No vmod needed....just o/c your cpu as far as it goes stable....then run 3dmar05....see what you get....if it don't hit 11k just o/c card a bit....but you shouldn't have a problem:)
I would think a 7900GTX should hit 11K in 3dmark05 with ease, even with no volt mod at all. My 7900GT does 12K plus at 1.5v and 724 on the core. So I think a GTX should do better than that. Thats with a opteron 165 at 2.7. So if your single core opteron can do 2.9 you should be able to break into the 13Ks with a GTX I would think.Quote:

FYI..nvidia has 84.43 beta driver posted on their website.
Do not look for artifacts. Its a waste of time, and half the time they are not visible. A better testing methodology, is as long as you consistently get higher scores as you clock higher, things are working ok. If you can run 3-5 quick consecutive 3DMark runs, chances are, its heated up as far as it will go, and its stable.Quote:

Changing clock speeds in BIOS is dangerous. The delta thing is how much faster the geometry processing part of the GPU runs than the other parts. Its typically in the 0-50 range (20 default for 7900GT). Changing to something else within that range will have at best a small difference).Quote:

And regarding over-volting and 1.3V. Sure, whatver. People are using stock heatsink even with 1.5V.. Obviously that results in the little dinky thing getting very very hot.. but hey, if the worst happens its not my video card thats going to die. Besides, by using inaequate cooling like the stock heatsink, you are inevitably limiting your overclocking potential.. you've already spent $300+.. whats $20 for good heatsink?
Why would you be concerned about the CPU? It might only give you a bit more on GT1 of 3DMark2005. Likewise, getting higher speed memory, and/or tighter timings would also increase by a few 3DMarks. If you are comparing to other people's high scores, chances are you should look into changing driver to "high performance" and increasing LOD.. these will make BIG difference (certainly more than overclocking your CPU even higher).Quote:

chances are you would get higher 3DMark2006 score with lower clocks.. ie, you've probably gone beyond its limit.Quote:

Wow, looks like 84.43 is the driver to have. 13422 in 3dmark05 is an amazing score with 550 on the core. Thats stock clocks for the overclocked models.
Dern I gotta try out that driver when I get a change. Wonder what 700+ on the core with that driver would do?

Hi all.
Got my Club 3d 7900 GTX couble of weeks ago but only now had the time to test it. Had to say that Im little disapointed for it. Here are the results:
Stock Speeds: 650/800
at these settings 3dmark05 gave 9970 points
3dmark06 gave 589x points
The Max OC that i could run was core 690Mhz and mem 839Mhz tried to run the core litle lower and boost the memory but no go here. The scores at the card OC'ed were: 3dmark05 10480 points
3dmark06 6225 points
My rig is: AMD64 X2 4400@4800 (220FSB) 2Gb Corsair LLPRO 3500 at 2-3-2-6-T1 220MHz. Drivers at use: Nvidia 83.21 and nForce4_x16_6.82
I wouldwe expected a litle more from the memory the 839 feels little too low =/ Tried to run CPU at 2.6 GHz but not stable there =/ So any suggestions how to improve my results ?
wtf...edit your post Pirs!!!

Try latest drivers 84.43 and see if you can clock that cpu more:)
Thanks guys for the info.
I wouldn't be too concerned about the memory not clocking as high as you see some of us. I'm pretty certain that the memory timings on the GTX cards are tighter than the GT cards, and thats why you see such high clocks on the memory on GT cards. Its also a different memory chip from samsung, which is faster to begin with. As soon as Nibitor is updated to allow memory timing changes i'm going to play with them and see what works best.Quote:

I found something i the BIOS called "PEG link mode", and the description of it was somethink like "... performance of the PCI Express card". Is this somethink I can tune to get a little more boost?
Finally, the 10k barrier was reached. :D

I had to use powerstrip to make these clocks. Coolbits just freezed the screen with core-clocks higher than 580.
Is that stock?! Thats a nice core if it is! Hey just a question, I just got my gt in today and the stock cooler is LOUD!!! I booted up the system for the first time a shut it down immediately because I heard a loud wooshing noise, after some searches I discovered its the gpu's fan! Lol, I have gotten way to used to water-cooling! Even with my high-end setup and loud rad fans this stock cooler is easily twice as loud as anything in my system. O well, gives me an excuse to strap my maze4 on it....
get that baby going and let us know how it does.
Everything is stock, no mem or gpu mods. Stock-cooler to.
All straight out of the box, stock heatsink fan and NO volt mods.

....where I'm talking about possible chip-memory/PCB issues....
My old posts about G71 over 700Mhz follow to the “freeze” issues: PC Perspective
Right after these news - many sites starts panic against GTX “freeze” issues. It was premature panic since now we have words from experienced peoples about the nature of these issues. After more detailed investigation of posts on different forums - I have conclusion:
1) First of all: NVIDIA says that some cards having isues when working on 700/1800 and higher- it's related to problems in communication between core and memory. I suppose it's due to different driving oscillator options for ROP, Geometry and memory.
2) The first words about pre-overcklocking from BFG, XFX, EVGA - the main reason - it's not true since many peoples says that even if they sets default clocks on these cards(pre-overclocked and with "freeze" issues) - it doesn't helps - the issue is still present. These cards have some defect element in their PCB - it can be bad chip or bad element on PCB(just try to remember issues with BlackScreen on 6800 cards - even on default clocks - it was releated to bad capacitors). These cards were RMA'ed and new cards were delivered to the owners - no issues on new cards.
3) The main number of posts with "freeze" issues were from EVGA owners. The root case was in bios since they were not able even to install default drivers from EVGA CD. Also, after new bios flashing some users still having problems with "freeze" issues - it's due to 2).
4) There are a few posts post in "freeze" threads about high temperature. Some GTX cards have bad or not correct installed cooler. Right after installing these cars from the box and playing games - the temp was more than 90C. RMA'ed - no issues now.
5) Some posts with "freeze" issus were solved via bios tuning. It was some kind of platform issues. (i.e decreasing RAM timings)
6) Some posts with "freeze" issues were related to overheat issues.
7) To avoid "freeze" issues - some time ago XFX and EVGA decrease their delta in the bios to +40. I suppose that first delta +50 was not correctly tested and it's hasty conclusion from Nvida.
8) The first reason of "freeze" issues due to OC - over OC: highly overclocked GPU - more than 720MHz is not stable due to clocks drops during high 3D load. It's all on default voltage for GTX and 1.55V for GT. It can be solved by increasing volts. Also, many 7900GT cards limited by 700-750MHz due to simple PCB and gpu limits.
9) The second reason of "freeze" issues due to OC - PCIe issues: proved that crads with more than 700-720 experienced problems with PCIe freq. I suppose it's due to synchro reasons between GPU driven clocks and PCIe. It can be solved by carefully PCIe tuning.
I suppose that new drivers - trying to restore 3D clocks after failure since if you check clocks after 3DMark run(with freezing in some subtests) - it will be 3D clocks. Also, if you check scores in bad subtests - you will see that scores in these subtests related to 2D or low-power 3D clocks.
So... If you have problems with "freeze" or PC shutdown during games on 650/1600 - forward this card to manufacture: it's real defect issue. If you have problems on clocks higher than 700MHz - check your temp and volts. In common case: 600-610MHz it's limit for 1.2V; 690-700MHz it's limit for 1.4V; 720-750MHz it's limit for 1.55V. If you volts and temp are correct - check you PCIe freq. In common case: you need to increase PCIe freq: it should be done carefully -> +1MHz PCIe freq then try to find stable OC for your card -> then repeat it: +1MHz PCIe freq and so on...
Hope this helps you to understand and determine your problems. :toast:
ps: sorry for my bad engl :slapass: ..."from Russia with love" (c)....
I just wanna throw in my results with the 1.5v mod on the core and the VF900-Cu and my 146 opty @ aprox 2971-3040mhz - I had a real hard time getting to the 12k mark, but i did it :) card clocks is 722/953 which where my max, before i got lockups or lower score.

I removed the 1.5v mod afterwards, because I think my cpu is a bottleneck even at 3ghz with a 650mhz on the core :)
Iam happy with my system though, for now :)
/Grau
My card "freeze" when I get over 610/1850, no mods done. Is this a "real defect issue" or is it just that the card ain't got enough volts?
It's just your card in need of volts, mine did the same at 610/962mhz which is my max on stockcooler and stock volts.

It's limit for 1.2V.Quote:

- what is the real Vram speed.. check in coolbits (nVidia driver)
- how did you measure these temperatures? Are they with stock heatsink? Please dont tell me you ran benchmark, then opened nVidia driver panel, and THEN wrote down that number as load temperature. You have to use rivatuner so it can log temperatures WHILE the benchmark is running (alt-tab windows, or checking after benchmark finished will give you lower numbers because GPU already cooled abit).
- once again, many people like you, with stock heatsink want to do voltmod. How much did you pay for this video card? be honest.. Do you want to break it because you are too cheap to spend $20 on after market video card cooler? Its the same as the conductive-ink problem: some of you people spend $300+ on this video card, and then keep bothering everybody about if pencil will work, because you wont spend $5 on some conductive-ink.
So to answer your question.. go ahead, and try 1.3V, even 1.55V, but dont complain if your overclock is limited, or if you burn up your card.
Please pay attention to what settings others are using! You are probably incorrectly comparing your overclocking results to those with 7900GT and 1.4/1.5V mod, or GTX owners.Quote:

Nilson, I think you are setting unrealistic expectations for people with the voltage scaling clock speeds you posted. Afterall, you say 610 is limit for 1.2V and eva2000 could barely get 590 on each of his 3 cards.
I think the following are much more reasonable values (assuming adequate cooling):
1.2V: 580
1.4V: 640
1.5V: 680
Ofcourse even though these are "reasonable" values, they are by no means "conservative", so dont starting posting complaing your card didnt reach 680, or something like that. I think a lot of folks here (especially with low post counts) are forgeting that a big factor in overclocking is "luck".. each GPU is different... maybe a few peopel can get a really good result, but many wont/cant.
yeah i think with 7900GT stock 1.2v you're doing exceptionally well on stock cooler if you can hit past 575+ mhz on the core

i use a zalman vf700 cooler:toast: , temperatures are taken from atitool running in background (and it records highest lowest and mean temp)and ram is set also with atitool since coolbits(i don't know why) stops @ 800mhz ... so i have to use atitool. for the temperatures i used atitool instead of rivatuner because i thought rivatuner whould not recognize it at all... but i'll try it!i'll look for conductive ink(if i find it,i'll look in some hardware store) anyway tnx 4 your suggestions!Quote:

My card will easily run artifact free at 680mhz core 1830mem but the scores get killed.
I've tried with the core staying high and the mem low and vice versa. Some how I can't get a good match. high core, high mem = good result :confused:
Graham drop the mem clocks to 895mhz ;)
for 7900GT it's like 10mhz on core = 35mhz on mem
loosing 10mhz on mem isn't much to scracrifice :)
Your not :cord: it enough :hehe: :slash:Quote:

Why the low mem clock? try 450 in atitool or 900 in coolbits, it should atleast run through a 3dmark with that core speed and you would perhabs break 7k in 06 and 12.4k in 05 ? Or perhabs iam wrongQuote:

My mem don't seem to be as good as others....anything above and it artifacts...and just tried 448 in atitool and my screen started to flicker and i had to restart pc...nevermind can't complain for a standard 7900gt.Quote:

yet to find the happy medium yet though. Still over 10k in '05 is ok :D

Anyone that own the XFX 7900 GT XXX can confirm the stock voltage @ 3D
Someone saying it works @ 1.4V
Yep. You are right. Sorry for my not clear post. In my post - I mean the bounds: the limits for G71 stable work.Quote:

690-700MHz it's limit for 1.4V - you can't get more or even equal stable clocks on this voltage in general. Usually we can reach 640-670MHz on this voltage with changed CO. I know several results with 1.4V and 690MHz stable - it's lucky GPU.
720-750MHz it's limit for 1.55V - it's really rare stable results. You can't get more than 720MHz with this voltage and be stable. Usually we can reach 680-700MHz. You should use at least water CO. I know several results with 1.55V and 710-720MHz stable on water - they are really lucky. I know several guys - they can set even 750-780MHz on 1.55V and 3Dmarks passed - BUT with lower resutls due to unstable GPU work.
In general we have lower results: you need lucky GPU and good cooling for reaching limit clocks.
My GPU is at most 545 MHz stable with stock cooling / stock voltage (base is XFX 520)
With 1.5V i am rockstable at 710 MHz all games / all benchs. I can bench without losing GPU cycles up to 740 MHz (depending on the bench). Cooling used for 1.5V is waterchiller set @ -20°c
84.43V2 Driver results. SLI'd BFG 7900GTs. Stock volts. Anything over 570 started freezing up about midway through.

How much can you get in mark06 SM3.0?Quote:

The instant, you are noticing 3DMark scores go down, you have more than just overclocked too far. A little bit lower setting might also give lower score every now and then. Maybe also check the PSU that its giving out clean voltages with multimeter, and try switching to another. Ofcourse when you are running both the GPU and MEM at very high clocks you are putting in a lot of stress.. usually cant get both very highs, its usually trade off.Quote:

7900GT SLI Asus and Galaxy vmod 1.55v cooled by VF900.
1st tests done at safe frequencies.

Deimos, ok I'll give it a shot

Not likely. If you look more closely you'll see I have a Socket 754 CPU. The lack of dual channel and dual core is killing me in the CPU section.Quote:

(please point the label from this capasitor if you have this card) Also, some capasitors were changed (purple labels -> green labels)

Hmm.. that could be better..or worse! Need a better picture and check out the brand, model and values of those capacitors.Quote:

Nice scores :)
Its a VIVO model too :clap:Quote:

I see two scenarios:
1. They have altered a few things to hold the clocks down to prevent this card to steal away 7900gtx sales. (Nvidia behind it)
3. They have merged the two top performers and added VIVO to the line in a "catch the moment" strategy due to the fiasco of the eVGA top models.
...I pray for the latter.:rolleyes:
