Not very impressed with BFG6800GT Overclockability

Not enough Jim Beam?

well maybe ill just toss this card out and buy an OC 6800 ultra and try to burn that one out to get
my +/- 10 gain

Life is good...but if your name is Rollo...life is better with Jim Beam!

Thanks guys...i....learned ....alot....from all of this??

Sorry for my remarks. I guess I haven't had enough Tequila

LOL..Why not go for the BFG 6800 Ultra OC water block card...Comes stock "overclocked (lol)" with a
470 mhz core...

I'd be pretty pissed if it didnt hit 500 mhz:laugh:

well damn it says 'overclocked' in the title of the card, id be a fool not to buy it then! lol
would be nice...maybe some day.

overclocking is always Your Mileage May Vary.

heat is a factor
power (both quality as well as voltage) is a factor
the particular chip itself is a factor.

and the difference between 370mhz (bfg OC) and 400mhz (ultra) is a couple fps. it certainly won't make any difference you can 'feel' when playing a game. mine bfgOC runs stable at 400-410/1200, but honestly it makes such little diffrence that since upgrading drivers (which removed coolbits) i haven't bothered running it beyond stock speeds.

I don't have student loans... the government is paying me to go to school . Have fun with your overclocking guys. I just want to say that for those who say or think that OCing something is a hobby, YOUSA CRAZY! OCING IS THE ART OF TEH DEVIL! IT KILLED MY 9600SE!!!! 480/500 with stock cooling massacred its sacred PCB!! Rest in piece...

I knew Satan had to be behind these OCing shenanigans. Could this be the Armageddon that was foretold?

You might have better luck if you play with different bios and maybe even custom ones. Thugsrook might be able to help you out as he writes custom video bios and did lot of work on Evga 6800 LE to Ultra bios. I would try PMing him for advice.

Good advice. Or you can just post up
here and he or one of the others will get you going.

I am highly upset myself. My X800XT PE won't OC at all. As soon as I hit find max core on ATI tool it artifacts. No lie, that is the truth.

The thing I am lying about is being upset since I was only checking to see if it "WOULD" OC. It won't. Not one mhz. I do believe Sapphire locked it for one reason only. It runs fine in overdirive. If I take overdrive and turn it off the card will NOT OC to 521 mhz.

How dare Sapphire take precautions on my behalf. Wait, maybe they are protecting my $450 investment.

Good job Sapphire.

Raising it just slightly creates artifacts in games like far cry and so on.
I just installed a nv5 silencer on it and the temps are running nice and cool.

Do some cards overclock better than others?

I'm using the 66.93 drivers, do different drivers preform better?

Anyone else seeing poor overclocks from this card or is it just me

Thanks

How did you like the nv5 silencer and was it easy to install? Was it necassary or was stock fans ok?

Some things I've learned about the BFG 6800 GT OC:

1. Of the two cards I've had (1 RMA), both didn't seem very capable of dealing with heat. The first was air-cooled with the dual-fan cooler that came with the unit. It would driver-overclock to 405\1060, but wouldn't run stable without a fan pointed at it. In all it didn't seem to function to well above 54c and would artifact and cut out. On water the new card hovers around 45c idle and never breaks 50c load, so far its running VERY well. Also, and I'm not sure this is an issue, but the card they sent back had the OEM cooler instead of the proprietary BFG cooler

2. In terms of power requirements, the first card I had didn't SEEM to get enough juice from a shared molex. The two SATA drives on the same line MAY have been an issue, either in terms of load or interference. The card I nave now is on a non-shared molex, and again, is running just fine.

My BFG 6800gt overclocks well i suppose I am running about 420 /1060 with no problems.. but honestly it doesnt matter, since i can run the latest games (doom3 hl2, etcc...) at max settings with AA and AF maxed

When I click that button in coolbits to detect oc my BFG 6800GT goes to 432 Core, 1110 ram. So I guess it is a crap shoot when it comes to overclocking, though as long as you are stable at core speeds thats all that matters.

Just remeber every 10C yeilds about 5% of stock.
Example:

Say with POS box cooler load is 70C and max core OC of the card is 380.

60C will yield you 380 + ( 350 x .05) = 397

50C will yeild you 380 + (350 x .1) = 415

and so on.. Now you see why people water/phase/LN2 their stuff. heat causes leakage which fails to OC. More volts is always a bad idea IMO.

why do you care about overclocking it right now anyway?

i thought the whole reason you spend that much on a card is so you wont have to overclock. there's no reason to overclock a card that isn't showing it's age on anything. it's dumb. just voids the warranty, and gives you a performance increase you will never be able to see, because by the time your card becomes outdated it will be fried by the overclocking.
