He looked around previously and looked into the specific hardware used on a Dell 7900 series card, from there he started altering things knowing the branding of the card He's been looking around for a while.

Also the reason I suggest the 790GTXUO.ROM is because it unlocks your clocks, as well as optimizes your memory, best combo. btw: I know how you feel being a geek and wanting to find out as much as possible to gain knowledge, the last couple years I've been hoping to work with a techie from a shop and learn more and more, but none of them want to take someone in and teach them. These forums helped out a lot.

The creator of this is Juanlu, Sergiop is another guy from the forum here in spain, first Juanlu take some info from the memory, craziepop give them one photo from the memory, Jaunlu finded the memory info from the seller, and changed the timmings according to the seller, don´t know how exactly did it, but he used nibtor to take info of the 7900gs and from the 7900gtx or the fx2500 from sergiop he compared them and did it don´t know exactly how, in the way he also finded how to unlock the card
Great job from Juanlu.

The creator of this am I, but I speak english so bad. Due to this, i can't explain the process in english.
In spanish forums there are a lot of informations about memory optimized and much more... See here if you are interested :

Part1
Part2
Part3
Part4
Part5
and more...

Sergio helps me in the translations. Very very thanks Sergio...

Two answers:

- Memory optimized load into gpu the optimum timings for the memory (Part5).
- There are ONLY two voltages available in the gs and gtx, 1v and 1,24v. The label don't change the voltage!!!!!! only the vid. (Part2)

Wow, thanks for the update. I will give this a try with my 7800GTX/m170 soon. I definitely like the ability to control the clock speeds with coolbits and flashing once vice multiple times.

Any chance for a memory optimization for the 7800GTX type guys out there?

Yes, im creator of nothing! XD... I just translated info from juanlu into english... so this is why my name is in between, cuz it was me writting juanlus findings!

Merry Xmas to all!!!!

¿Cas tú por aquí?

Basically

Vid 0 1 2 3 Voltage = 1
Vid 4 5 6 7 Voltage =1.24

Doesnt matter if you put in nibitor to use 0.8 or 1.32 this is just a LABEL. It has no effect on performance...

Im not gonna look for the post where he explains it cuz its allready 3am and im pretty tired, but its on one of the ones he put above...

Yolda you do not know what you are saying.. Tomorrow sergio will explain this detailed in English. Thing that I cannot for my English..

pm me the info in spanish or german as you like

About the timings, agreat fellow helped me to use it, centi is his nick, hes a master on this, and we found that there is no performance gain in altering the timmings, not even on max or min clocks allowed, how? well testing FPS, Synthetic scores and ofcourse stability, there is also a reason (on part 5) that says that dell uses different timmings to get money, but thats not true, cuz these timmings are for this specific memory and just like the gpu they ar eall different, So you may be lucky and get a GPu that supports up to 675 MHZ i ionly got one that gets to 625mhz setting the delta offset to 15. With the memory is the same and the fabricant says that "Maximum clock frequency up to 800MHz"" and that is we all have expirenced with the gtx Bios on tthe gs, So using the GTZ bios after all infact changes latencies . neverthe less this is a great Thing, cuz finding out how ti unlock them is hard, GRATZ you have made all our lifes more easy!!!!! Gracias!

On the secondpart, about the vids, hes right.

On the third part about timmings too, asumming that lowering timmings to lower max clock speeds as a marketing technick....well its doubfull, but try these, use the GS bios to up his timmings (even if nbitor shows that GS and GTZ bios have the same timmings /and hessaying he used that program). Now if you get the same memory frequenzy with the GS bios (800mhz) then the timmings are changed indeed, if not... well i am allways here to tell you, i told you so...

cool, seems to work fine with 7800gtx, gracias amigo!

I'll play about with it more in the next few days and fire you off a dontation

Merry Xmas!!

(and thanks to everyone whom helped him, nice one!)

how's this effect battery life? When I unplug my laptop I have the card go to max battery and I get 2and a half hours maybe of battery life.

when i print in XXXXXXX.ROM.

is it just print 5001000.ROM ? (if i want to have 500/1000)

and then its run in 500/1000, and i can use nvidia controll panell, to put it back to stock settings, or rivatuner to makes profiles and have 2 differents clock settings ?

and can please someone make a nice step by step, about whish ROM you should use, etc.

790GTXNN.ROM ,790GTXUN.ROM ,790GTXUO.ROM

no difference in all Timingsets 0-7 with Nibitor !!!!
Artefact DEEP Freeze 3D 06 610/710 , 600/710 --->790GTXUO.ROM

i have a go7900gs, whish Rom should i use ?

For a start I would resp. I use the the 790GSUON.Rom

@all
So what now please. Are 475Mhz for the core good or bad for 1V ?
And have I understood that any voltages except 1 or 1.24V are impossible. I mean only two days ago even overclocking the card at all was impossible for me.

And the difference between optimized memory and non optimized memory is really strange. With both versions I get with the same clock frequenzy exactly the same 3DMark score except that without optimized memory I get artefacts with frequenzies over 600Mhz. With optimized memory i can go as far as Rivatuner allows what are 750Mhz.
