Yes, I have 2.87@3.3, 1.25 for vref, and 2.5 isn't modded :stick:Quote:

This is exciting and I should have my VR's any day now.. Great job, thanks for sharing. :)
Ok, from what I can gather, the 1.436v is vref. But I am not yet 100% sure. It seems that some are calling this memory termination voltage. I don't know what that means. I'm pretty limited in my knowledge of this stuff. I dropped out of the Electronics Engineering Technology program after a year and a half. So here is what I figure all the voltages I measured are:Quote:

1.436v = VBT (Voltage to Bus Termination)?
1.545v = vgpu
2.859v = vmem (operating)
2.961v = vddq
I have no clue if this is right. If someone with some knowledge could help out it would be appreciated.
Whoa, so it really seems to work. Damn, i've had voltmods on my Sapphire 9500np for a month now, but the problem is that i've tested only mild increases :). :rolleyes: . Ok, i just have to test this, after my Assembler exam is done :slobber: . My mem does 297, the memsinks didn't help, but i haven't rised voltages too much ;).
BTW, here's my card:

and some parts used for cooling:

ok,
but probably with ramsinks (and cold air ;) )
you probably can do 310
Okay, had some fun with the card :).
I ran 3D Mark 2001 SE's lobby shooting to test memoc. 3 loops, both lo and hi.
As i had allready seen, 297 was max that didn't produce errors. This was 2.90V Vdd, 1.30Vref and 2.96V VddQ (i don't know how that was so high, i can't remember leaving it like that... :) ).
Next:
Vdd = 3.01V and
Vddq= 2.55V
303Mhz runs through the test fine.
3.11V Vdd 310Mhz runs throught the test fine.
For 317Mhz i need 3.31V to get it through fine.
324 is too much, even with 3.45V. I left it to 3.4V, because i got some mild rendering errors with 3.35V and 317Mhz when running whole 3D Mark through. Will see if that works :D.
Vref and Vddq don't seem to have much impact on the overclockability.
Another thing i've noticed with my card: rising Vgpu produces only lower oc-possibilities. With 1.47V i get the best oc for GPU, which is ~380 stable. I can run benches @390, but not 100% stable.
Yeah, played Jedi Knight II ~2 hours 384/317 and no probs :). 1600x1200 and smooth as silk. Gonna run some benches later.
OT: just came from 'avantouinti' which means that in the winter time, you make a hole on ice and go swimming on the +4 degree WARM water :). What an rush of energy, whoa! Sea is a good place to be in winter... heh.:banana:
Geeezzz! Until I read about the Warm +4 degree water and swimming in it....I thought vmods to the video card was exciting! LoL :DQuote:

Dane, you've done well. I've applied all four mods to my 9700Pro Rev3 and now she just smokes. I'm just waiting for an MCW50-t to show up, then I can really start pushing. Thanks for all the help. :D

I'm waiting for wb and later coldplates :D :D
Well here is the tale of the tape so far. Before any mods 380 core 348 mem. After all the mods 425 core 366 mem. This is with the following voltages:
Vref = 1.447v
VDD = 3.000v
VDDQ = 3.015v
VGPU = 1.586v
I don't want to push too many volts into it just yet. At least not until I get some better cooling.
On my gigabyte 9700 pro the vref is stock at 1.43. I get some sweet mem overclocks with that combined with the stock 3v setting on the ram. I think a nice vref mod will help u guys with ur mem oc'es considerably
The only problem is, if you up vref too fast, or too much, you smoke your card. :(
Dane, what bios did you use to upgrade your 9500 NP to 9700?
Okay, I'm totally lost here... I have several questions.
1) Why are there 4 voltages?!
2) What does each do and what are safe levels for them?
3) Which pins raise each?
4) Where are the measurement points for each voltage?
5) What did you use for ground on each mod?
I've only done 1 voltage mod and it was on my KX7 with clips...
Heh I'm w/ Svenn here... he asked me to try and make some sense of the mods...
Please draw either a diagram, or a digicam picture w/ LABELED points. I'm sure one of you guys can do that. Keep the pic high res too if possible!
ok guys let me help you a little click this link and you will get a little more than the pic. :D
looky here
http://www.xtremesystems.org/forums/...&postid=117898
For all of these mods that need to be done?
Was looking for pics as Bowman had stated, but couldn't find any.
So there are 4 mods in total that need to be done?
Any help would be greatly appreciated. Thanks!! :toast:
Also need measuring points for voltages... :D
i need to do this mod as well
my powercolor 9700 non pro v3.0 core oc so damn well
390 un modded, untouched
but mem as expected is a piece of §§§§.. 3.3 ns hynix but only 310 @ stock..
if anyone can wack up a conclusive volt mod pictorial will be greatly appreciated, all those links contained too much information for gfx volt modding newbies like me to absorb ;)
I did all 4 mods already. When I get home I'll put something together. I couldn't find one place that had a complete guide to all of the mods, but I managed to do them all successfully. :toast:Quote:

ah cheers :) :banana:
I could also use a better guide to the mem mods. Modding the core was a piece of cake but I really need some mem mods for my Retail version 3.0 9700pro.
I got my core up to 479 but I can't get my friggin mem over 355.
I haven't forgotten about you guys, I'm working on it right now. I'll post it soon. :toast:

i want to hear from dane about how his card is handleing 3.3 vmem
I don't know how Danes' card is doing, but, I was running my 9500np at this everyday and on AIR with a 3Dmark03 score of 6095! :) VDDQ=2.800v, Vgpu=1.820v, Vref=1.350v and VDD=3.503v! :eek:Quote:

Now if my new 9800pro would just do that! ;)
