[Denny]eVGA 7900GTO testing

i have not yet eVGA's video card for a long while :rolleyes:
XFX yayayayaaaaa :D
anyways..... GTO... half price of GTX but user can easy flash to GTX's bios and run as it.....but remember, those are the recalled card from GTX becasue the ram is not wroking with GDDR3 1600 stable

box of eVGA 7900GTO

black sticker and i think it is ugly XD :p:

One item to consider, the memory timings. Looks like they have tightened things up versus the GTX. The card runs faster with the original BIOS versus using a GTX BIOS. Just mod the stock BIOS if you want to tweak.

timing-----------GTX-------GTO-------BJ11 ------ BC14
tRAS------------24-----------22----------25-----------22
tRC-------------34-----------31----------35-----------31
tRFC------------43-----------39----------45-----------39
tRCDR----------12-----------10----------12-----------10
tRCDW---------8-------------6------------8------------6
tRP------------10-------------9-----------10-----------9
tRRD-----------8------------10------------8-----------8

So, looks like 1.1 ns Samsung GDDR3 may be on there, but, since it only has the 1.4 ns spec voltage(1.7 min, 1.8 spec, 1.9 max) versus the 1.1 ns voltage(1.9 min, 2.0 spec, 2.1 max), the timings have been adjusted accordingly to 1.4 ns just like the GT cards.

thx for the info. but i already tweak the bios.... actually tweaked test already done.... i am doing to stock test now lmao

edit... the ram volt at 1.9v that is right but even flash to GTX bios is still at 1.9v, i am trying to use nv offical bios ultilty to change it but not sure....

The cards were physically reworked. So, there is no BIOS fix for the memory voltage.

I just got two of these and I have a couple of questions. What driver are you using? I dont want to use the one you say only for testing. But mine stops at 800 for the memory how are you getting 835? I used coolbits to adjust mine what did you use? I have the p5w-dh deluxe so I have to use modded drivers I am using the 85.96. Thanks.

Why not for 24/7 denny? I planned on ripping the delta out anyway...
10-05-2006, 11:50 AM
tommyshango

how are you possibly running these cards at those clocks? It falls to pieces when I get even close to that. Completely artifacted. If thats even a word. I doubt these clocks. or if its only for a score on a benchmark and not even possible to run at this speed normally then who cares. Cant be good for the card.

@afireinside
not for 24/7 becasue memory timing and speed
later today johnny will have some mod out. i already saw it and that seems good
with that, my bios should work perfect

@tommyshango
becasue you need to remove the delta clock
driver doesn't make overclock different
bios does!

Damn is that 850MHz with 1.9v?, mem clocked well on stock bios in your case despite the 1.9v if that's correct. I wish mine also does similiarly but I don't have that much luck usually. :D

Tighter timings wasn't expected but does make some sense tho.

I won't flash my MSI 7900GTO to GTX bios personally if this is true that they just can't handle more voltage without possible failure as this card needs to stay with me for several months. But reading this thread it appears the voltage doesn't change and only the timings and that would cause the higher o/c results in some cases or is this 1.9v limit despite bios flash only limited to eVGA for example or does it also include MSI cards hmm..

I have to ask what you think about it, does this mean Nvidia were overvolting their own products and that caused problems for some well pretty many 7900GTX owners in fact, whetever it was stock or overclocked speeds, seems like these memory chips doesn't live healthy with more than 1.9v and hence they release these older GTX cards with prolly an older type of memory (I think they've fixed the prob with the newer 7900GTX) as a 7900GTO with another BIOS that reduces memclock speed from 1600 -> 1320MHz and memvoltage 2.1v -> 1.9v and also with tighter timings on the mem, which means faster speed at same clock than a GTX. Guess these cards would have been dumped otherwise and they decided to not do that and do a further investigate (well they probably knew the prob :rolleyes:) which lead to the 7900GTO. I'm suprised so many reaches above 800MHz (1600MHz effective) speeds on these cards tho despite the tighter timings and lower voltage, I hope I'm one of the lucky ones as well...

I got like 700 and 700 roughly but that was just a really rough estimate I have only played with them a few hours so far. Thats using the sli hacked driver cuz im on the p5wdh deluxe. I was artifacting at higher speeds and a few blue screens I will see what I can get.

10-06-2006, 01:16 PM

There was a sticky on it, not sure where it went. Anyway nvidia has 3 "clocks" rop rom something or other. Anyway delta only raises one, not all 3. That means with a delta you might wall the one clock and the other two still have some left. Or something like that.

Curious about that as well, Are they just as hot on GTX cards ?
I'll cool the chips on my card with ramsinks, cut to fit, attached with AS Epoxy.
10-15-2006, 12:49 AM
Garrett

Good luck with the ramsinks then, have you noticed the small resistors on the left of each of them? Those are higher than the chips :(
They make an easy installment of any ramsink a lot more difficult, since you have so little surface to work on...
10-15-2006, 03:37 AM
Alexandrus

I know the resistor is higher, but the ramsink is cut really small. I just would like to know if those temps are normal on all GTX cards, because if they are, it would be pointless to add the ramsinks.

No camera, no computer(just a lousy old laptop until I get a decent E6600).
The heatsinks are cut from a blue ramsink that came with the TT Blue Orb ages ago. I started cutting them into small pieces for mosfets and got a few extras lying around.

Does that area get EXTREMELY hot on your card? How do you cool it? Did it get worse with vmem mod?

On the other side there is a black heat sink there but out of 3 rolls of transistors the last 3 vertical rows of the 3 transistors are half the height of the other two rolls bearly touching the heatsink. I put more thermal paste on mines but only brought it down by maybe 10 degrees but still pretty hot. Need to put some copper slim there.

Hi

i just got a 100K ohms variable resistor for the memory
BUT i cant get it up to more than max 92.2K Ohm
where do i land if i go with 92.2K Ohm for the memory?
over 2.0v right?

Hey i've got a big question.
So 100k for mem and 200ohms for GPU are the maximum value for these variable resistors right?

Because...

Down ohm =====> volts up

????? right????:confused:

So when i install these resistors the first thing to do is to measure the ohm value to be sure of it.:cool:

The second is to turn up the Computer and measure the volts to be sure that arn't too much high:cool:

RIGHT???????:confused:

So now, can i change the resistor value when computer is turned on????:confused:
Naturally with multimeter i'll verify second per second the volt value !!!:cool:

It's all right????
Help please!:p:
