The HD 2900XT Info Thread - Page 123

post #1221 of 1286
Hey guys...I guess I should ask it here

Is the 2900 being discontinued or something, because from this moment newegg doesn't have them in stock or even on their website at all.

Anyone knows?

Really? Or newegg don't want to sell them anymore or something.
I think newegg probably don't want to sell it anymore due to cheaper R600 called the R670XT.
Anyway that's why I have to push my XT to eat up other GFX for good i.e. R670XT.

Yep it's like asking why they don't have Big Block Pontiac FireBirds for sale at the dealership anymore

These "gas guzzlers" will still tear up the streets...but the push is on to more efficient power. By the Next gen these babies will have ssen their day in the sun.

lol. Overclocking the HD 2900XT can eat past the HD 3870 performance provided with efficient cooling.
More like tunning up the engine and more efficient cooling in a Pontiac.

If I get the HR-03/R600, I can forget about adding another R600, man, I kinda hate my Gigabyte GA-P35-DQ6 MOBO with such a big NB heatsink. And not to mention at the bottom of my case is taken by a PSU.

Yeah I hung in there for a while. But the exhaust off the Crossfire set up at idle was actually heeating the lower floor of my home. Dropped back to a 1950pro and since all it does is idle 24/7 that's wayway better on my ears and ambient temps.

I will always remember the HD 2900 XT Crossfire rig though...it's like a muscle car...20K 3D06 is still a highwater mark for most systems.

lol, have you ever seen HD 2900XTs hitting the 30K mark in 3D Mark 06?
A pretty tough bunch of CF HD 2900XTs to hit that high and some new components too working with it i.e. CPU, Mem, etc.
lol, I can't see Nvidia Ultra in the top five Hall of Fame. Ultra got pwned by XTs.

Although Ultras are more powerful in game.

I nevr had the time in my shcedule to spend an entire day tuning cards. OCing in CF is a time consuming process. And then to go LN2 with all that tuning? Insane. Thos are the most dedicated and Xtreme bunch of OCers in the world.

Never knew that it can take all day, but it seems pretty insane in Futuremark.com Hall of Fame.

The way to Tune in CF is to first tune the CPU/RAM etc and get that where you want it because your CF CO will be lost once you reboot.

You need to change your Monitor preference in Displays to th second card OC that card till you find the highest stable point in single card mode then switch display back to the primary card and OC that then go into CF mode.

It could easily take a day if you were not already sure of what settings might work. Passing 06 at the extreme edge of stability is a trick...and a system hang that requires reboot loses th CF settings.

Now add LN2 into the quation...you are going to need at least three people to OC: two to pour and one to fget the OC up which will take at east a few minutes. Then cnsider the fact that retuning to find what the cards can handle under LN22 re Upping Vcore and flashing different BIOS for better timings etc it's way beyond what I can imagine doing in this life time.
