When I was ordering my 7800GT I ran into that same wierdness...

Had to pick from 4 different S/N's...

514
515
516

Can't remember off had which one I got...
But I know that you are getting the GS...

Point is get the one with Higher Factory Clock..

Ogden Utah ha, I'm moving there in 17 days!

As far as the "NS" I would have to look that up again...

EDIT:

The smaller the number the better...
Kind of like looking at a size of the wire, when looking at the
CPU NS, the smaller the better...

Oh yeah? I know folks in Hooper, know the area. My wife was living there when I met her. Her parents still live there.

So for the 1.4 ns ram and 1.6 ns ram, is the lower number better for overclocking then? 1.4 ns, that in relation to speed isn't it?

thats how im looking at it.1.4ns should overclock to about 700mhz minimum and 750 more likly after overclocking to the max..

K4J55323QG-BC12 800MHz 1.6Gbps/pin Pseudo Open Drain_18 136 Ball FBGA

K4J55323QG-BC14 700MHz 1.4Gbps/pin

K4J55323QG-BC16 600MHz 1.2Gbps/pin

K4J55323QG-BC20 500MHz 1.0Gbps/pin

so if this is the case then the memory on the cheapest model should be able to overclock higher. yeilding a higher Gbps.....

1.6 is rated for about a max of 625mhz (1250mhz)where as the 1.4ns is being OC'd to about 725mhz(1450mhz)

One more quick question:

Between these three models I am seeing and hearing these differences from forum groups:

7800 GS CO Superclock (EGVA fan N509) 1.6ns memory , CineFX 4.0 engine, Intellisample 4.0

78800 GS CO Superclock (reference fan N508)

7800 GS CO (Evga fan N506) 1.6ns memory, CineFX 3.0 engine, Intellisample 3.0

7800 GS (Reference fan N505) 1.4ns memory, CineFX 4.0 engine, Intellisample 4.0


Is the 1.4ns memory better? I am hearing the lower this number the better overclockign potential it has? If so why is the Superclock card at 1.6ns memory? And why would the (N505) with the 1.4ns memory be the cheapest card?

Also, what is the difference between the 3.0 and 4.0 versions of the CineFX and Intelisample?

Which cards have the better copper heatsink?

Which card is the overall best if i want to overclock it myself for the fastest speed?

Just in case anybody is interested:

I called EVGA and spoke to one of their techs tonight. Very nice fella! Anyway, he has clarified this for all of us:

All 4 7800gs cards that they offer are at 1.4ns memeory response time. The 1.6ns was a typo.

Also, three out of the four cards state that they have CINEFX 4.0 and INTELLISAMPLE 4.0. The 7800 GS CO states it has 3.0 versions of these. This is also a typo. All four cards have the 4.0 verisons.

The other thing he clarified is that the 3 cards with "CO" in the model title have better copper heatsinks, while the bottom of the line 7800gs (model N505) does not.

There you go! So in conclusion and to affirm what a lot of people have told me, buy the 7800gs CO (model # N506) with the evga fan (got mine for $299 with free shipping from circuit city) and overclock it yourself and save the dough!!!!

Thanks to everyone for their advice and help on this!
