Seems the X1900 XTX are cherry picked cores

Looks like XTX are cherry picked cores and that's probably why ATi is charging $100 extra for them. I got the itch to OC the new XTX I bought last night and it clocks to 750/900 without breaking a sweat. I think I can easily push the core to 800 mhz or higher but want to wait until the AS5 settles in and my ramsinks arrive. The XT I had on the other hand was barely pushing 720 core and 840 memory before artifacting. I've been reading xtremesystems forums and with the exception of a few people, it seems the XTX cards do clock higher than the XT. So despite having the same ram, most of the XT's don't clock as well as the XTX do. I suppose if you are an overclocker, that extra $100 for the XTX may be worth it.

I suspected this might be the case. For someone that really wants to overclock the hell out of their card, the XTX might just be worth it.

That's cool and all, but, I thought most overclockers motives are to save money and overclock rather than buy the top (most expensive) of anything. This goes for everything mind you, not just vid cards. CPU's, RAM, Video cards. I suppose one could try to overclock a laser printer if they really tried. :D

Well there are those who treat OCing like they would a sport . . . ;)

Yes, but don't forget that once the "PE" designation hits it will probly be the same core. So in essence, you are getting a "PE" version for X amount less. This is of course that they release a higher clocked card. Then you will see your standard for an overclocker take root :)

Interesting. Would you mind posting what voltages you're using on your card Joker? Also what cooling is on that beast?

I'll take that XT off your hands since it's such a bad Oc'er and you dont want that... :p

I was under the impression the XTs were already stretching the clocks, then the XTXs were the supercores that reached even higher somehow.

Your impression seems to be correct;)

Well that is only partly true. Some overclock to save money by purchasing lower end models while others want to push the envelope and get the absolute best performance they can. The XTX is for the latter.

All stock voltages, I don't want to mess with them until there's a newer version of ATi Tool and ATi's OC utility out - guess that makes it even more impressive huh? I'm using a DD Maze 4 GPU water block (1/2" fittings) to cool it down. That's why I'm waiting on ramsinks because the stock cooler cools them down but right now there's nothing there. I'm also going to attach some sinks to the voltage regulators.

Heh already sold it to my cousin for $475 yesterday. :) Mmmm XT/XTX: Text

What program are you using to clock it?

750? man thats awesome.....5150 your a bastard:p

that cards gotta kick ass at that speed, im betting that as soon as the G71 is out....a new bios emerges for these cards, because they are obviously capable of so much more

Yeah this XTX card is fantastic! Right now I'm severely limited by my old 3000+ winchester (clocked at 2.5 ghz) and the X2 4400+ I have on order from Dell is on backorder and won't be shipped until Feb. :(

Actually it's not, if you look at Joker's results. He got a 720 overclock on the XT. That's a pretty respectable overclock so the XT cores are hardly "stretching." The XTX's just overclock a little bettter because they take the chips that test the best and put them on those cards.

What temps are you getting Joker? I'm hitting 70c load with a zalman at stock speeds

Joker,

Would you give us some FEAR and even 3dmark06 benchmarks, before and after the OC? I'd like to know how well it scales with raised clocks and extra bandwidth.

Aren't the stock voltages on the XTX higher than on the XT? That might explain OCing differences.

I believe we have a winner.

Anyway, I don't doubt the XTX cores are capable of higher clocks, but wouldn't do it. I don't have* $600 to flush if I toast a card through electro or thermal migration. To those with the means and inclination, salute. ;)

I suppose I "have" it, but the gains of OCing high end parts never seemed close to worth the risk to me. If you want some real performance gains 5150, you should Crossfire and leave'm stock!

Actually, neither of you are totally wrong, or right. As in all PC components, YMMV.

help me with this a little

why does someone buy the single fastest GPU for $650 and then o/c it?
:confused:

i can see doing it with a lesser card or an older card to squeeze extra performance . . .

you are already getting the "best" performance - if you need more, that's what x-fire is for.

edit: OMG, i just agreed with Rollo :Q


:shocked:

Since when did people not ever not take advantage of someting being free? I don't know about you rich people but as a student, I take advantage of all "freebies" that I can.
