I'm getting one next week for my new CAD rig. WOOT!

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

**iboomalot** · 11-14-2005, 05:08 PM

my X1800XT on stock cooler in a warm enviroment got over 10K in 3d05

AAC your Rig makes mine look slow lol and i know its not.....

great scores being thrown arround here well done

**M.Beier** · 11-14-2005, 06:01 PM

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.

**Vapor** · 11-15-2005, 03:48 AM

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

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)

.
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.

**Tim** · 11-16-2005, 08:07 AM

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...

Leadtek btw....watercooled by Maze 4

POV are good cards or not???

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

**jetjaguar** · 11-17-2005, 08:12 PM

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??

**Tim** · 11-18-2005, 07:45 AM

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

**Ubermann** · 11-18-2005, 09:04 AM

Have you tried Force performance mode in rivatuner ?
