ATI's only hope at this point is CF as we have yet to see what it's capable of on X1800 platform in the right hands.

Or if they boosted the pipes to 24 or 32.

Sure but thats not gonna happen on X1800 ;)

20k within reach?? - They're gonna make some badass drivers then, cause, usually nobody beats shamino ;) - Or at least not by much...

im thinking with the new drivers that take the sli overhead and give the work to the other core the dual core may be faster?? could anybody that has these powerfull cards test this?

holy crap! anybody know if these numbers are even the least bit accurate?

Yeah, wonder what it is capable of with just a sligt voltage increase :)

Now I am thinking if the evga step-up program is going to worth the money.

eVGA's step-up MSRP is $699 and there's a long ass line, get in it now if you want a chance of getting a card this month.

A GTX 512MB can past the 11K :D

Im not sure, I would think so with the new drivers though.

My x2 clocked at 2.5ghz (7800GTX@ 500/1400) scored the same as my Opteron 146 at 2.9ghz (same GFX card speeds) :fact: .
If you can get a dual core to run that high, I would think they would score better. But I have no way of backing this up besides what I said about my x2.

I'll have one tomorrow or Friday.....only store in the UK who had them left in stock.....$860 USD lmao....such a ripoff...but I'm happy...

Having trouble getting my BFG over 623 core, is this about the limit on stock volts? My memory will not pass coolbits test past 1850, is there an overclocking tool with memory timing. Maybe if I loosen them I can get to 1950 and see if the bandwidth helps :)

I read its some limitation from the drivers, but can be passed with rivertunner but i dont know how :(

Anyone can help here??? Same problem...

Riva Tuner > Power User > Disable Clock Test

hmm my bfg did 630/1890 using coolbits on stock cooling and stock volts

anything higher then that and it fails the test in coobits

I have done that...
But the problem now is every time i OC with the rivatuner test, the card runs only with low3D clocks...must be some error with rivatuner and this card/driver version...
For example: i put the card in rivatuner @ 650/1900 and in 3DMark05 it only runs @ 500/1900...the core doent run at correct speed.
Anyone has experienced that??

Really CPU limited here....but I'm still impressed, I can't imagine what a 3Ghz A64 would do... :)

260x10 = 2600Mhz - Dram 180div : 236Mhz 2-2-2-5-1T (max CPU speed is 2673Mhz)

The GFX frequencies was as high as I could get, disabling internal tests gave me a much lower score...even at 625Mhz with no artifacts at all...

617/1850

'03 : 22032
'05 : 10563
AM3 : 97,241

Pleased with the results :toast:

Have you tried Force performance mode in rivatuner ?

The explanation for that is what i have said...
When you disable the internal clock test and OC de card with rivatuner i dont know why but the card runs in low3D clocks, 500/the value you set for memory...the core stick in 500...

Power User > enable perf. lvl forcing,
then when you OC > Force constant perf. 3D setting.

You may have to just back up your BIOS using nvflash in DOS and mod the clockspeeds with Nibitor to get it to set right.

Aight, thanks guys...I might give that a shot tonight :)

I think I won't bother to play with DI or LN2 since I can't do voltage modifications to this loan card. Shamino, kingpin and Kinc are showing some insane numbers ;)

Volt mods on my cards go tomorrow. Going to run 1.65 on GPU with water and 2.3 on memory with heatsinks...

One of the two XFX cards I have is a monster out of the box. No mods stock air cooling it's artifact free at 661/1950, the second card can only do 641/1920. The single moster breaks 25k in 3DMark03 at those clocks with my FX-57 and nearly 11.7k in 05. Now time to volt mod...

Looking to fire the system up today and test out the cards. Like I said, 700/2000 is my goal with volt mods although I think the cores will probably go higher than this... :D

You're right, with the volt mods, 700/2000 should be a piece of cake. :D

Max overclock with coolbits, Mmm I hate Rivatuner but may try it out..

Just got one to test it..

I'm really impressed with these 512MB GTX cards, just mount the card do a quick bench with stock cooler ..and get this..

http://pedrorocha.planetaclix.pt/120...ck637_1870.jpg

Instant 12K in 2005 :slobber:

With my previous GTX 256MB, also stock cooler and the FX-57 on vapo more or less at same speed ..

http://pedrorocha.planetaclix.pt/101...00GTXStock.jpg

That's almost 2K in 3Dmark2005 gain with a revision of the core and faster memory speed..

ATI may be in serious trouble in high-end market if the X1800XT PE and Crossfire don't came out very quickly ..I'm a long time ATI fan but I have to admint this .. :(

That's awesome... I really need someone to teach me how to tweak these nvidia drivers and OC these cards. I ran 661/1950 (stock cooler on air) w/ 3.65ghz and scored 300 points less than you!! :slap:

Fx-57 on VapoLS, small voltage, and even mem voltage at only 3.2v ..

44K with 1 graphic card with o stock cooler ..no bad for start :D

Pedro is that a XFX or BFG card?

Can anyone tell me if the MSI card is any good. If so I have to buy one while they last
