HEXUS has learnt that ATi Technologies has sent out an official communication to select Add-In-Board (AIB) partners, that endorses an increase in the clock frequencies at which products based on its flagship RADEON X1800 XT (R520) ASIC can be shipped at.

Personally, I think it's a desperate attempt to keep the crown....
But nVidia's partners do it...why not ATI's? :)
euuuhhhmmm?
what did nvidia do with there 7800 512 GTX???
they upped the vdd and oc'ed the card:) and added some faster memory.
and some minor changes, call this desperate?
You can obviously look at it from different points of view ;)Quote:

We should be seeing some innovative coolers as a result of this, looking forward to the day the XT goes into mass production and we actually have some choice from AIB partners. But their primary obstacle is just that: mass production of these high end parts.

This announcement ammounts more to raising the stock clocks rather than announcing that AIB partners can pre-overclock the cards.
i saw this coming a mile away.
I dont like this from any of the companies but specially from ati, they had all the time in the world to launch a final decente card.
anyone knows the clocks? and new price?
they are waring with the price... war to the 1000 dollar price tag :lol:
It's desperate, because ATI has never done anything like this before.
Exactly...IIRC the only company who released overclocked cards with ATi cores was HIS.
I wouldn't call it desperate, but it's definitely an attempt to try and bring in some attention.
They're crazy if they think another 25mhz on the core and ram is going to handle the 7800gtx 512mb card though...
See but HIS and other extreme cards had to use external applications to overclock the cards within Windows if I recall. They still weren't allowed to change the clockspeeds set in the BIOS.
just wait till gainward release their golden sample watercooled 512mb GTX, likely to see 625mhz stock in the bios, ATI wont compete with that for a while.
Lets keep this fight on air =)
dont give them ideas :slap:Quote:

In the past this has been where Ati has risen above nVidia. It seems like everyone is *so* concerned with how each card goes about doing what they do (high clocks vs more pixel pipes)....but I for one am more concerned with the kind of overall experience each card provides in a given game.
ps-if this is that far off topic, MODS please feel free to start another thread in the appropriate place.
sheesh....could you imagine the crossfire board that would accomodate 2 of these beasts? LOLQuote:

The XL core has no problem matching XT speed stock, that is a problem as people can mod the XL in a flash. This is also a problem for GTX as I can drop speed on my XL and match the default 2k5 score of the new GTX 512 (and have image quality).
The XL memory should be bumped up to 1600Mhz and the XT to 1800+. The XL core could go 100Mhz bump
The big point in the X1800's is HQ filtering...that is simply awesome...Transparancy AA is IMO slighly better lookign then Adaptive AA, but there is only so much that you can tell ofcourse by looking at screenshots...Quote:

Anyway, I'd say it's pretty off-topic :p:
the 1.2ns ram is rated for 1600mhz so i dont know why they dont take advantage of the full potential of the ram for both xl and xt, and the 1.1ns ram could be used on the xt if aib partners want to release their own special editions with 1800mhz speed. In terms of core clock, the xl's are using the older lower clocking cores, so a lower clock allowed ati to clear out their stocks. the newest revision gives excellent yields at 650mhz+ so this boost makes sense, and speed binning may provide an even higher clocked PE or even a product tiered between the current xl and xt clocks - maybe even the xl clocks for the new core being raised.
Nice point, when I watch a jet dust the carrier deck or Black hawk skin cruise a few feet above the water it lets me the X1800 delivers the best visuals hands down.
I have the GTX missed out on a lot for the first few months of BF2. Another problem I had with the GTX that was driver related that many of you may be experiancing. When I opened a scope and it would often close the scope down, usually when you needed to shoot to save your own life.
I play at best quality on both but I did have Rivatuner loaded and the profiles may have been resident on the GTX reducing image quality thinking I needed frame rate.
The memcontroller on the R520 is the problem. It can never handle 1600mhz on the XL with the vcore it has. And vcore can't be upped on the older revision core because it isn't stable then. The card would need a better cooler; remember that these cards have to run in the hottest cases in the hottest inviroments around the world.Quote:

It leaks power so they had to lower it a little making the memcontroller, designed to be used with 1.4v, incapable to use 1.1ns memory for the X1800XT and therefore ATI used the cheaper 1.26ns instead.
The powerleakage is just a theory but it is known that the cards need higher vcore for high memory frequencies.
Higher vcore is needed indeed but the card is still maturing quickly.
interesting... You still think there's more hidden power on die than what's been shown?Quote:

Alexio the reason for 1.26ns ram is that it was the fastest one available at that time i think.
1.1ns is really new and went to mass production recently.
And looking at the price for 512 GTX its alot more expensive then 1.26.
You are probably right about this, I thought about this but I wasn't sure.Quote:

Its in some pdf file the date it went to production gonna see if i find it.
They both use 2.0V± 0.1V is what i see so far..
September 25th 1.1ns was added to the pdf file and i guess it went to mass production a little later then that.
Nice find.
The 1.1ns ram was probably produced as 1.2ns, but speed binned as the process has improved to the point where yields at this speed are in sufficient volumes.
That's unlikely......1800Mhz isn't the max of the memory...sampsa has his memory up to 1890Mhz...now your not gonna do that with 1.26ns memory I think :)Quote:

1890 on stock air at that...Quote:

Dang Nice...do you run your rig at the 10k 05 settings 24/7 ?
Perkam
As much as I like the X1800XT, I don't think a clock speed boost of a mere 25mhz will do anything against the 7800GTX 512MB.
Nice OC fugger, btw ;)
Nice clocks! I can't get my 1.2ns past 819mhz ( 1639) looks like I have a dud...is the card iced up - or air @ 73C?Quote:

Not bad...but I have a feeling that cooler is bigger than it looks, remember the ATI stock isn't entirely a rectanble...this is :eek:
Only thing is, once the Arctic Silencer for the X1800 hits, there'll be little use for this :p:
Perkam
that is one chunky cooler, man. Massive.
What the hell is this? for an external power supply? lol

Yes it is.....same as the Dual GPU's from ASUS....cleaner power, takes away the human factor in getting the cards to run at that speed (as in people using crap PSU's and still expecting their cards to function perfectly fine)Quote:

I might have found a piece of info that might alow higher clocks on the core. What we are seeing now are R520 rev A14 and A15. Dave at byeond3d states theres a A23 out there too.
http://www.beyond3d.com/reviews/ati/r520/index.php?p=11
Read whats on this link about A23. The queston is what is A23 and why are they not being used right now? Could this be what a X1800XTPE will use?
more freedom in setting clockspeeds = more competition = good :)
=higher price =)
