since you got a waterblock go for it!

unfortunately puts great load on the system so i dont recommend it up to you guys
Nice work. Can you expand on your comment 'puts great strain on the system' ? They look like 330uf Tantalums, that shouldn't load it up too much capacitance wise although the cap size may change the timing of the circuit inappropriately and a different size may be better. If you feel 330uf is not optimal, can you try something in the 100 - 270uf or >330uf range? The Direct CUII is running 470uf tantalums and the GTX480 uses 390uf polymers.
thanks.. from 4.8ghz i had to lower i7 980x to 4.6ghz then when liquid temp rose had to lower to 4.4ghz unless i kept the liquid cool i had system instabilities
thats i used the very same caps used on the rest of the card: aluminum panasonic ecg polymer 2.5v 330uf 6.0mohm esr
at first i was surprised too just how much load it felt like lol but after the results im ok with it
yeh i couldve gone with 470uf or like the ones on gtx480 but since the waterblock covers over these caps i was in no mood to try different capacitors+capacitances
i didnt test single card went straight to 3x cards but for a single card id say this mod is a go the load wouldnt affect the system as much
That's odd, to me that sounds unrelated. Having to lower CPU 400MHz to remain stable and then experiencing instability as liquid temps rose sounds system (not VGA) specific. Unless your cards became unstable at same clocks/voltage (and in fact you said you gained clocks), I'd suggest it's something other than those caps causing the CPU issues.
The caps don't cause the card to draw more power, nor run hotter. They just filter the mosfet DC output and the only added load would be the initial inrush current at power on when the mosfets have to charge the caps.
ok, tnx for the advice, i'm waiting for a 360 rad, then i'll koolance my evga ... :up:Quote:

When I placed in the PC...My VID GTX 580 is 1.000V
Nvidia Inspector

What is the command for flashing GTX 580?
Nice 1V VID
If you use nvflash (and you should ;)), use commands "nvflash -r" first, it disables protections. Then "nvflash -4 -5 -6 580bios.rom".:up:Quote:

You have to call your saved bios you want to flash 580bios.rom in that example too btw.
How well would you expect this to overclock? I have one that I havent tested yet and have listed it for sale, so tempted to keep it....Quote:

hi, i've got the same vid, msi reports 1.000 but gpu z reports lover vid,Quote:

BUT...
1. 3DM11
- SS + 6core CPU@5300MHz + GPU@990MHz on water. Score 75xx :down:
- SS + 6core CPU@4000MHz (just to see the difference) + GPU@990MHz on water. Score 75xx :down:
2. 3DM11
- AIR + 6core CPU@4400MHz + SS on GPU@1080MHz. Score 77xx
- AIR + 6core CPU@default + SS on GPU@1080MHz. Score 77xx-7805
WTF i don't understand this 3DM11 :confused:
This is not possible. Why 1xxxMHz brings no difference?
@p3gaz_001
Both, at idle the VID lowers to reduce temp and power usage.
I probably have the highest stock VID in this thread lol 1.088
whaaaaaaaaaaa 1.088? ahah ... wich temp do you get on your sys? :)

stock cooling? (i don't think) wich brand is yours, how much voltage for 1ghz? plz :up:
I think he wrote "water".Quote:

Probably gonna try 1.000 @ 850Mhz core next week, highest I tried to OC my card with at stock volts is 900Mhz Core, I dont know how to start or even check for memory stability so I didnt touch it.
Stock cooling? No hehe. Water. Max on water with open window 1006MHz.Quote:
