8800 gt differences ??

[edruns69]

Is there any difference between these cards from Evga...

e-GeForce 8800GT 512MB 600 MHz GPU
e-GeForce 8800GT Superclocked 512MB 650 MHz
e-GeForce 8800GT KO 512MB 675 MHz
e-GeForce 8800GT SSC 512MB 700 MHz

other then there clocks are set up a notch??? Wouldn't you be better off buying the base 8800GT (least expensive) and overclock it yourself and save some money? Sort of a noob at this. Thanks.

yea you could probably save some money that way...the oc results ive seen so far have been extraordinary

The only difference is the speeds they are guaranteed to work at. A regular may not even run at 601Mhz but if it works at 600 then you are stuck with it because that is what was advertised.

yes, but that probably wont happen... i mean look at the oc's people are getting its rare that one of these wont do at least 700mhz core

Thanks for the info. So you think they have tested the G92 Chips back at nvidia or evga and put the best chips in the more expensive boards?

well yes... but at the same time nvidia is getting such good yields that they have an abundance of highly clockable chips...so even though alot of the really good chips get put into the stock overclocked cards just as many if not more get put into the reference clocked cards

I bought a Kotac 8800gt (Kotac are owned by Sapphire) which comes overclocked at 660/1600/1800 at a standard price. Mine easily clocks to 700/1700/2000. Most games worked well without issues at those speeds - Q3A E+ does not get the card's temps out of idle!

However, I had a problem with those speeds in the Crysis demo. It would play it well for half an hour without issues, then, with the menu up, it would freeze. Bioshock again worked well without issue for half an hour then froze. Either there's a built in clock deciding when to freeze or heat is the issue. I reckon the latter. The fan on the 8800gt did not speed up in either case. So, either the sensor is not detecting extra heat from the GPU or it felt the heat there was okay. If the latter, then the likely culprit is the RAM. I turned down the RAM clock to 1950 and all has been well so far.

I will change the cooler and heatsinks later. But this card is fine so far. There's no certainty that these cards will overclock but most do but by different amounts. I doubt I'd be able to tell the difference of 50MHz.

BTW this card idle shows 54c if I put the fan to 50% this drops to 48c. I think part of their problem in where to set the fan speed is noise - people complain. So they get conservative. Pushing mine to 50% gives basically no noise. 80% and it whines a bit. Controlling temps is the key to overclocking.

yea your deffinitely heat limited with that oc, you need to crank fan speed up like you said
