8800GT bios for better overclocking! *test*

[CryptiK]

Just save and modify your own bios with nibitor to the highest totally stable clocks, and flash the cards one at a time (ie: remove the second card, flash the first card, then remove it and put in your other card) using nvflash v5.57 or later.

[Sn@ke:~]

The ram they use is rated at 1000 MHz (2000 MHz effective), so it should get to that speed ok. One consolation: OCing the ram does not gain a bunch or performance. It's the core clock that makes the big diff.

Sorry to bug you on that quote, but I have to do this. It is not true both core and ram bottleneck cuz of the hardware past 900 mhz core you won't see any improvement if you can give enought power to maintain it and the memory will bottleneck at 1100 mhz due to the maximum timing and power the hardware can handle and I also heard that these Qimonda on 24/7 will get permanent damage eventually. Today's GFX card are bottleneck due too memory speed there is also the mobo chipset involve, but not as much as GDDR memory . Why do you think nvidia's next move is to go GDDR5 on a gtx 2xx that they will call GTX 3?? or whatever by the end of 2009 and/or beginning of 2010. Thought that what you said used to be very true , but certainly not these days.

look at this:

BTW anybody got succes with tighting the timing on these Qimonda mem and if so what are the timing changed at. I would like to combine the timing config with this vmod :-)

..or with loosing the timings for higher overclocks.
I got a MSI 8800GT Zilent with that VF1050 zalman cooler but in ATI Tool i get artifacts if i go further than 1025MHz so atm my clocks are at 777/1950/1000 with vGPU voltmod. The vMem voltmod didn't help anything, i went up to 2.3v vMem but i couldnt even squeeze out 10MHz more. Anything higher than 1025MHz gives me artifacts in ATI Tool.

[Melhisedek]

Sorry for bumping this thread, but I've been trying to overclock my card and have heard about this mod.
I've backed up my bios and to my suprise it says that my voltage is already 1.15V

As I'm using Windows 7, can someone of you guys check if this is really true and also is it really possible? Someone told me that voltages can't go over 1.1V

And if you chose 1.15 or 1.2 that voltages drop to 0.95V (?) which is default...

Any ideas?
Thank you for your time!

I know this is a severely thread is old but how come?????

i was able to whip an 8800gt at 800mhz/1030 with only a 9600gt oc???
(bfg 9600 gt oc (not oc2) at 740/1018) on g31 pcie v1.0 mind you!!!!!



is it 64 bit improvements or have i got a really good one here???
cause i was thinking of grabbing a 8800 gt since it's like 50 bucks now)

or would there be no improvement at all???

just curious

(saving up for a 6870 though)

thanks

If SM3 score is higher than SM2 score, it suggest Disable Post-Processing is enabled

Vista/ W7 is sometimes faster than XP in game tests

Old drivers (pre 18585) are slower in 3D05 and 06

[Gameman]

ok thanks i have no idea what post processing is - i only ever benched it on the most basic settings because my first monitor ever was 640x480!!!! believe it or not (have 1080p now)

thanks though

[K404]

resolution will have a pretty big effect too

[Gameman]

quick question:

is alpha-dog 8800 gt better or worse than 8800gt superclocked?????:

(forgive me funds are low - getting 6870 in new year)
thanks

just want to be able to play crysis on gamer at 1280x800 and get more than 28 fps (like with my 9600gt)

6870 in new year (only temporary)

[K404]

Theres no binning, they'll very likely OC the same and the difference in FPS between them will be minimal... buy whichever is cheapest or looks better and OC it

[Gameman]

thanks - i think the alpha is the 256mb version so the choice is even more clear...at least till 6870 anyway

thanks

[Gameman]

TALK about no binning - apparently the new 9800gt is exactly the same as the previous 8800gt - just a name change

here's a Bfg 9800gt oc vs an EVGA 8800gt superclocked edition - EXACTLY THE SAME...

.

the reason i'm mentioneing this is because i thought i was taking a step down by upgrading from a 9600gt oc to a previous generation 8800gt but apparently it's the same thing - just an older naming scheme...good job with the WOOL...

I guess that's Nvidia at their sunday best

anybody know what's the deal with the missing bandwidth on the 9800 above???
thanks

ps: if they're all the same then does that mean a 9800gt at 600/900 would clock exactly the same as 8800gt superclocked edition at 650/950???
cause judging by above they appear to be 100% identical

[BeepBeep2]

Wow, that was news two years ago.

9600GT to 8800 GT is an upgrade. 9800GT to 8800GT is the same thing (if at same clocks). Nvidia renamed G92 to hell, even up till the Geforce GTS250 cards.

[Gameman]

I see thanks

the only reason i'm looking at cards this old is i can find em for dirt cheap
and it should hold it's water until i get the 6870 later...

i see g92 was also 9800gtx and gts 512

well thanks for the reply..at least i can survive on this card knowing it's not a SIDE GRADE anyways...

thanks

don't get me wrong - i'm not outta my mind here - it's just that i found one brand new that a friend never used or opened and i figured it was cheaper than a new 5670 (only temporary though)

thanks

[Gameman]

PS: I just happened to score 2 of the old 8800gt's
(one is evga sc 8800gt and the other is alpha dog 8800gt 256 version) - same g92 though

anybody have a problem running em in SLI in this board here
the only one newegg.ca has left by the way???
http://www.newegg.ca/Product/Product...scrollFullInfo

cause i heard this board can do fsb in the high 400's cause i might dump my g31 775 for this and keep my e5400 at 4.0ghz

I know newegg and google have reviews but i wanted an opinion from someone that actually knows what they're doing...

i wasn't even gonna bother but i got em basically for nothing so...

seems to have all the necessary options:




thanks

[K404]

They are classed as different cards because of the amount of GDDR each has. You can't SLI them

[Gameman]

I SEE well i'll just use the lower one for benches separately, but IF i can find another 512 GDDR3 then i'm good to go????

this makes me miss Crossfire - you could even pair different cards among the same series with different ram and clocks...oh well

I guess thats NVIDIA for you

ps: any chance i could fool the board by ing with the bios???
cause i know some guy got a 8800gt and a 9800gt to SLI together ...can't remember where though...

or does bios modding merely only fool the CARD...

cause these are only temp until 6870, they mean nothing to me - and getting another one for 40 bucks if i unload the alpha dog should be easy

EDIT:
I also heard that 8800gt sli is somewhere near hd5770-hd5830 - which is getting into 6800 range anyway so....???
i dunno, just thought it'd be fun...
at least until i can get a 6870 or 6790 or whatever they come out with next spring

thanks


EDIT2: also i know p5n d sucks a major amount of @%$ for overclocking but it HAS to be a step up from g31 anyway

besides i've tried 4850 in crossfire so i figured it would be fun to compare scores, see if i could even break 20000 in 3d mark 06

[K404]

You *might* be able to tell the 512MB card it's a 256MB, but I wouldn't recommend it... if you flash the BIOS, you do so at your own risk

The 9800GT is the 8800GT, flashing that BIOS is different

[Gameman]

Thanks

hey, i figure for a 40.00 card what's the risk??? (either that or i unload the 256 for 40.00 and grab another 512 / or another 256 (which ever oc's better))

Thanks

any thoughts on the p5n d mate???
i figure it's probably about the oc equivilant of a gigabyte ep45 ud3l which was another cheapo board i used successfully...

looks like 4 phase at least and all the voltages and dram ratio is adjustable
(no vtt/fsb termination though - ) - but i should at least get what i got on this cheapo g31...

if not then forget it because the next in stock board are the EVGA's starting at 250.00-300.00 big ones....

thanks

[Gameman]

The 9800GT is the 8800GT, flashing that BIOS is different

btw what if i was to get a 9800 gt instead with the needed 512 (65nm version)
and flash it then - would it technically be the same thing - since technically it is??? or is it hit and miss???

cause i know of a 40.00 bfg 9800gt oc a friend may be willing to sell or rather UNLOAD on me...

thanks

sorry for the double post: i guess quotes added in later do that...oops

[K404]

My thoughts on the P5N-D are not suitable for a family-friendly forum

Your card... your call bro Do whatever ya want I'd be interested to see if it works

[Gameman]

ok that's kind of what i thought too...

for 40.00 bucks why not...

but i'll hang onto the trusty g31 just in case i blow em both AND the board

seriously though - SOME guy i read was able to do and even do benches

i figure if it even can trade blows with two 4830's or two 3870's it's worth a try...
cause then it's like getting a 3870x2 only lower power and only 40.00

but like i said...keepin it cheap here...


now that i think of it i'll be flashing the cheaper one definitely..since i think it has a defect anyway...

I also have access to a used 9800gtx+ oc by bfg
now technically they are all 8800gt's right???? right up to the gts 250 etc??? (8800, 9800, gt, gts 512, gtx etc)

any chance i could flash either of these cards into thinking it was the other since they are both g92 with the same transisters and nanometers etc????



or is there even less chance of that...

thanks

[Gameman]

My GOD.... that must've been a good 9600gt oc I had...

i scored only 500 pts more in 3dMark 06 and this was with the Superclocked 8800gt (brand new by the way) overclocked to 720mhz and 1036 memory...



The 9600gt oc was already oc'd by the way and like the 8800gt sc oc'd even further to 740mhz and 1018mhz memory...
but the clocks are close enough
anyways, those 48 more shaders of the 8800gt sc only amounted to 500 more
in the synthetic benchmarks anyway...



Crysis however was where i saw the biggest difference - which is why i upgraded to it anyway - i went from 26-28 fps on Gamer/High with the 9600gt oc (oc'd) to over 46 fps average on the oc'd 8800gt superclocked edition on Gamer/High which was what i wanted...

yeah i know i paid roughly 60.00 for 48 more shaders but you folks were right despite the synthetics it IS an upgrade

Bill Gates though here, seems to tell me that's it's more of a SIDE-GRADE...

oh well...

Sorry bro, you're wrong. They're all G92, but not all like the 8800GT

8800GT and 9800GT have 112SP
8800GTS 512, 9800GTX have 128SP

As far as I know, there is no way to unlock an 8800GT. No-ones ever done it, to my knowledge.

Both 112 and 128SP parts were refreshed to 55nm as G92b but that (for a nice change) makes no difference to inter-card behaviour they will still work with their 65nm stablemates as long as the BIOS is flashed.

Side note... if you want to submit on HWBot, please don't do any of these things. Submitting results with a card pretending to be another card is classed as cheating, regardless of matching specs
