7900GTX vs 7800GTX512 vmoded

**Vapor** · 03-09-2006, 09:00 AM

That is bad info....there's actually 5 and they're much more tightly grouped.

L - reference
F - 665/1.63
E - 675/1.7
P - 690/1.75
D (XXX) - 700/1.8

Even the GTs are wrong

:-/

I will tell you tomorrow when i recive my XFX OC version

**bachus_anonym** · 03-09-2006, 09:18 AM

@guess2098,

Interesting comparison! I understand, that you have RAM timmings tightened IDENTICAL, on both 7800GTX & 7900GTX ? I'm looking forward to see how far core clock will go, without vgpu mod. Since it's a die shrink (90nm) it should/might give better results without voltage bump.

@OPP,

It's a good news that 7900GTX seems to not complain about the cold! Are you using MSI mainboard/gfx combo?

**AACDIRECT** · 03-09-2006, 09:21 AM

Just got off the phone with XFX. I was told the numbers were correct... I asked for them to confirm. They are double checking and are going to get back to me.

For those that think I am smoking the crack rock....

**guess2098** · 03-09-2006, 09:29 AM

just woke up... many questions need to reply~~~~~~~~
@eva2000
voltage for 7800GTX is 1.6v which max out at 685/1950
temp is about the same as 7800gtx512 but there are some weird thing
one of the card report 44 while other one is 29...... i switch the slot, the temp result is NOT follows the card
ex. card A in slot 1 reported 44C, while i switch to slot 2, card B will reported 44 and card A back to 28C....

@vapor
i think is the driver issue ... don't know know yet

@kakaroto
yeah the clock speed is exactly the same

nachnthymnen
thx bro

fixxxer
i believe so, but 7900gtx under air with "nvidia version"; ram is hard to oc and core is only around max 680 under 06, but 05 is good too 700...

@perkem
sup bro, remember, 7900gtx is still not yet vmoded and overclcok heheheeh
for real? some of them uisng 1.2ns?

@cupra
after vmoded i think 7900gtx is going to fly

@opp
man..... that is carzy... r u already vmoded?? you r quick ... heheee
wait for your score....

@bachus
i don't want to answer your question lol jkjk
the timing for 7800GTX512 is tigher than 7900GTX for sure!
vmoded for me again? heheh

to9 i am going to give some non-vmoded 7900gtx overclock result

I have NVIDIA samples. I'm using DFI Expert along with my new 1k PCPC PSU

**mascaras** · 03-09-2006, 09:39 AM

so 7900 dont have AA+HDR and HQ-AF ??? and the only diference btwen 7900GTX and 7900GT its nle the memory 1.1ns and 512mb ram and the cloks??? but if the diferences are only this , its better buy 2x7900GT for same price as 7900GTX no???

Thats weird because Monarchcomputer has the PV-T71F-YDP9 at 690/1750

As does NCIX:

Where have you seen this model?

**rapty** · 03-09-2006, 10:11 AM

I am receiving the XFX GeForce 7900 GTX Extreme Edition 512MB GDDR3 VIVO TV-Out/Dual DVI (PCI-Express) - Retail (PVT71F-YDER) (GX-073-XF)
memory clock is at 1700MHz and clock at 675 what sort of memory will it have 1.1ns? or 1.3?

I presume it would have the 1.3..

Regards

**rapty** · 03-09-2006, 10:12 AM

J mag that model is here I bought the one just under http://www.overclockers.co.uk/acatalog/7900_Series.html

**SIOUX** · 03-09-2006, 10:20 AM

wow...there is a lot of OC versions comming

Even the 7900GT has the same hole at each corner layout, but the rest of the points are slightly different, I think (might be wrong at that).

In short, your waterblock will work, regardless if it's just a block or a full-body. If it's just a block, it will also work on the 7900GT, the 7600GT, the 6800s, the X1800s, the X1900s and the X1600s.

Thats great news, even less work to put proper cooling on it

Finally nvidia is keeping a mounting layout (all the way back to the 6800 series)

**kiwi** · 03-09-2006, 10:25 AM

Cause they are all awesome clockers?

**pumbertot** · 03-09-2006, 10:33 AM

cant get 1680x1050 so i ran 3dmark06 on 1600x1200 with 16AF on the x1900xtx @700/810 (stock volts) and got 4950 so im a little disappointed at the 7900gtx as I had hoped it was going to be well ahead not just similar.

anyone else disappointed?

**AACDIRECT** · 03-09-2006, 10:37 AM

Just got off the phone with XFX.... the price sheet I got had the wrong specs. When I asked were those specs came from. They said it was a mistake. (Kind of strange as I got the pricesheet yesterday.

)

What do you guys think?

BTW I was told the XXX edition is not available yet. So the fastest part now form them is 690. Anyone find the XXX in stock?

Kind of makes me sad. At 750,1.9 on factory air the cards would have ruled.

what is ur cpu speed?

**rapty** · 03-09-2006, 10:41 AM

The place I got mine today had the XXX version this morning in stock

**DelaMaris** · 03-09-2006, 10:43 AM

Why does 7900 GT have naked mems?

I SEE BIG NUMBERS

GTX or GT. Anyway I am intereseted in see what you guys can do with these cards. (Sorry for all the thread crapping.)

**~~freecableguy~~** · 03-09-2006, 10:44 AM

That's the $64K question. That's the card I want.

1-3 days = not in stock

I would imagine that we will see these in stock in the USA by Monday or so of next week. They are lagging the other cards by just a few days.

No cold bug and need very little voltage. I was playing with one of mine yesterday for a little bit before I blew out my OS. Just getting started and reached the 900s with the core at 1.7V, didn't get a chance to play with the memory.

hehe...damn straight

**IvanAndreevich** · 03-09-2006, 11:04 AM

Oohh.. NCIX has lots of stock. It wasn't there two hours ago. Not even a single 7900 card on the site.
