mysterfix, what were your end voltages for the 630/1390 you have in your sig? my 7800gt does 492/1140 with auto detect and can do 500/1200 without any issues. haven't tried anything higher as of yet.

I'm at 1.7v gpu (3d mode) and 2.36v vmem. My card performed almost identical to yours at stock voltage so you may see about the same results as me.Quote:

Thing is i don`t have 3k resistor, so i wonder if there is possible to use 1k , 2k or 10k that i have..
10k will work, that's what I'm using. I set it to 3k before installing and rechecked it before booting up.Quote:

Managed to take 9k in 2005 and 19k in 2003 aircooled :)

Did the vmem mod now, but didn`t have 10k so i used 20k..
Mem runs at 1300Mhz now whitout artifacts..

what volts on the mem fosco?
2.45vQuote:

2.2v does 1300
tried 2.25 and couldnt even pass 1320mhz???? does this seem right?? like its giving no gain?
well others are trying in the 2.4-2.6 range so i guess i shouldnt be to worried to go alot higher hehehheheheh
anyone know of a case of this card dying from like 2.5 vdd voltage??? any opinions if this is this ok long term with ram sinks and a decent airflow?? im thinking it should be fine because 2.3 volts is only 10% higher then stock so a little above that should be fine heheheh
Modded over thanksgiving, used 10k's for both as that's closest I had. Stock on my evga could get to around 480/1150. 1.62v/2.2v gets to 553/1300. It feels like the memory has a lot more but it's running naked so don't want to push it. maze4 acetyl does about 41 C load.
Quick question. When you do the V-mod on mem and GPU does it always stay at that voltage setting?? Even in 2d?
In other words after you do the mod can the volt levels in the bios change the card or does the volt modding completely overide those settings?
Debating whether I should do the bios volt mod or the hard mod. Which is better?
naked mem huh?? how hott do they feel?Quote:

The Vcore is next to get some abuse/attention.....I`m controlling it through BIOS at the mo..want a hardmod so I cant control it in real-time. :)
it's funny i was at first scared to run them naked even without the vmodQuote:

then again, one of my 120mm rad/fan is blowing underneath the card, and given that the core is running at about 40 load much of the heat can dissipate through the pcb to the core to the water.
good point ghost thanks for the tips
i got a 120mm door fan blowing on the card so i think that helps but i got ocz copper bga sinks installed now anyways but i must say they get quite warm with the volt mod
infenion 2.0ns ram btw @ 2.25v

Just finished mine from http://www.vr-zone.com.sg/?i=2656&s=1
Original vcore 1.401
vmem 2.05
After mod
vcore 1.45
vmem 2.18
I haven't upped it at all, that is with the VR's are ~10k ohms
Auto detect before only let me get to 489/1170, now 505/1190, can't wait to start testing <3
Make sure your wires stay tight to the board because with that much extra they could get yanked off easy...
I know, I have them glued down at various points :D
Question, I was monitoring my core voltage while playing, it went from 1.437 and slowly rose to 1.46 then spiked all around. How reliable are these potentiometers?
The variable resistors themselves are very reliable. The problem you were seeing was probably the Vgpu drooping under load.Quote:

are there any v-mods out for the new 7800 GT layout?
http://www.newegg.com/Product/Produc...82E16814150124
well, I don't know if it's a new layout but the one XFX uses...
how long will these cards last @ 1.6v??? i've got 1.5v bios mod, and i can do 500/1310. gonna try 1.55v and just leave the mem as is. hoepfully the results will improve a little when i get my psu back and i dont have to deal with a 10.9v on the 12v line underload.
Oh yea this is with a STOCK x2 3800 , ocz 3200 plat 2-3-2-5 1t 200mhz. Shooting for mid 8k's @ 2.8ghz.
EDIT : My 3dmark 05 score was 7941 like this, and 1.55v bios mod i was able to 510 on the core which yeilded 8055
The core volt in 2D and 3D is different.. And thay are that also after av vmod.. So, if you have + 0.1v in 3d you also get +0.1v in 2d....Quote:

ok, just for my benefit, could somebody explicitly point out the grounding points on the card? Are they any of the 6 points or 4 holes, just above the PCI-E connector?
