9600GT oc clock speeds w/wo v-mods

is that a picture of the cape?

at any rate look in my quide in my sig it covers bios modification...diff card same thing.

No its the Gulf. Southwestern Florida. I will look at your guide. Thanks

Sol could you look at you info in the first post. Are your oc clocks the same, what mods are you using and do you have any benches with the cpu @3.6 Ghz?

I've read about several strange cards that were found in retail boxes. Most were second owner purchases so what box and whats in it are questionable. Did you get yours by means of retail exchange? Gotta wonder how these cards come about.

the cooling for this card is rubbing me the wrong way (two mistakes in two days). I picked up what was supposed to be an accelero s1 rev 2. Not paying attention, I failed to notice I left with an s2. I installed it only to be dissappointed by the temps I am getting under load. I checked the receipt and the clerk entered s2 so thats what I bought.
I don't feel bad when I screw something up while I'm learning something new, but when I do something stupid like this ... well I guess it's a good thing I can't put my foot in my own ass!

Note to self: PAY ATTENTION!

 

[MKmods]

sell me the S2 (I like mine) and could use another.

MK I'll let ya know in a few hours. Going to see if they'll exchange it. Doubt it though.

does the accelero extreme work with the 9600GT? I haven't found it listed anywhere, but they could be slow updating info so... anyone?

accelero s1 rev 2

k got the right cooler now, and added the turbo module. Temps are better but my gmem liked the reference cooler better. Stable oc is now 829/2075/1140(2280) with temp not going over 42*C and it is a fair bit quieter. It's not silent as some have suggested (@45% fan speed I cannot hear the fan), but there doesn't seem to be alot of difference in cooling between 45 - 100% fan speed. Now this experience has spawned another project: at some point I'm going to put together a rack for liquid cooling the gmem. Seems simple with the pcb layout. Similar to the asus mb w/c heatpipe set up.

I am under the impression that watercooling graphics memory has very low return. Overclocking is limited by 2 factors. The first is heat... higher frequencies = more watts. The second is electrical limitations of the silicon. i.e. you can cool something to close to 0 deg Kelvin but the silicon is going to have an upper limit based on the electrical limitations of the silicon design. I believe that memory is limited more by the second factor.

So with the GPU you can get huge extensions in the overclock potential by massive cooling efforts since it is a high power device in which heat limitations kick in very early. However, on the memory you can get a "little bit" of OC from massive cooling but you are already near the electrical limits of the silicon.

Just seems to me that the cost and complexity (all the additional tubing and connections and restrictions) added by WC the memory does not provide considerable return on investment.

However, if someone has examples of large gains in memory OC by going liquid I am all ears.

I agree, that pretty much sums up what I've learned as well.
Sometimes it's just fun to create. I've been kicking around ideas for a copper case and this seems like an interesting addition.

il post up some benchies in a few and ya the odd card was a resualt of a retail purchase got it at best buy....it was teh odest thing and my oc clocks top are in my sys specs

Here is my 9600GTs

[Solaris17]

nice good job dude.

 

[MKmods]

cool part is its a Biostar 570 (8X on the PCI-Es) and its like 100F here, stupid desert. Il push it some more tonight when it cools down.

hey hey dudes, after trading in my high-pitch-squeal asus reference 9600Gt back, and getting a 9800GTX, i again have come across a 9600GT but its odd....

its the asus 1Gb model, with the glacier cooler.

tried to oc, all attempts locked up, so reverted to stock for benching, lowen behold, it was not even stable at stock! so RMA.

got the second one.

runs great except for 1 thing. it wont oc at all, like the first, except it is stable at stock.

any ideas? this is the first nvidia card i have had in a long time that wont even budge on speed without artifact/crash...

its just weird that the reference model, with the disgusting noise, oc'ed well (something like 775 core, 2000 mem) and this non ref model with better cooling, wont budge!

remember its the 1gb model.

Help!

voltage your using is?...

only cooling mod so far...
these are the factory voltages:
gpu idle: 1.17v load: 1.21v
gmem 2.12 v

with the latest drivers and the accelero S1 v2 with dual fans, I game at 820/1100 and it hasn't gone over 39*C.
the gmem liked the reference cooler better.

edit: sorry, it's configured for 1.15 but measures at 1.17 idle

 

[Skitzo]

I'm curious. I don't have a good understanding of the power circuit on this card so bare with me. If a 0 ohm resistor completes the voltage config paths, would it be possible to increase the value of the resistor to lower the power increase. If a 0.05 increase trips the protection circuit, maybe 0.04 wouldn't. Is this possible?

This is in reference to my card that has a factory 1.15 volt configuration. To make a 0.05v increase it only requires completing another pathway.

=wolf;Help!

Sorry Wolf, missed this post. This is new to me, never heard that before. Lac of power maybe. You wouldn't think a card strung that tight would make the market though.

in theory this wouldnt be a bad idea the only problem is after volt modding the card with largons tutorial your raising the OVP cut out point. the problem is is that under load or at various points during load the voltage is fluctuating which triggers OCP because ocp on these cards kick in only a little bit after the voltage increases over the set limit....what you could do to stop this fluctuation is Over volt the card then but a resistor in place to drop it back to what you had it at....this might stabilize the current going to the core.

thanx Sol,

just tossing this idea around right

I'm not sure I understand the theoretical solution your suggesting.
is this what you mean?
do the 0.05 increase configuration and use a resistor to drop it 0.01v
to 0.04v to test my idea.

so to me that would suggest a new resistor between the core power pin and the power pathway.


Just curious, but if I wer to start shorting pins as a process of elimination, how many 9600gt's do you think I would toast before I found the pin to disable ocp?

thats kinda what i mean you see raising the voltage via voltage modification raises the ovp/ocp limit to my understanding the problem is is that when the card is under load it has a habit of fluctuating up. an alternative i had was instead of going through some mad complicated reroute you can over volt it to say 1.2v than just solder a resistor in place to bring it back down to 1.15 or you can use a petanometer this might in theory might stop the fluctuation of the voltage so the card doesnt trip

 

[Skitzo]

aren't the fluctuations cause by load demands. could limtiing the fluctuations in effect starve the gpu momentarily when there is supposed to be a little spike?

i think it isnt because the GPU is demeaning more voltage i think its just because the circuits fluctuate under heavy current draw.
