8800GTS 512Mb (G92) vMods

My Vmod...

[wolfgang]

ok I still haven't maxed out the mem on this card. Its at 1200 I bumped it up 10-20mhz at a time ran the firefly test in 06 looped 3 every bump. Mem is at 2.12 and the core is at 1.44 load. Next is the prommy on cpu.

My Vmod...

That's some tiny wire you got there.

[Achill3uS]

i've made today some mods on my BFG GTS...
vgpu, ocp, cap mods + measure points
can't wait for some subzero action with
but at first i'm going to test it on air...

[wolfgang]

http://service.futuremark.com/compare?3dm06=5579087 18.4k with this vmodded card 1.6gpu 2.1mem. It was clocked at 881\1200.

[aussie-revhead]

Wow Wolfgang your q6600 gets 4.3ghz benchable on water , what batch etc is it ? With those mem clocks thats samsung mem right ? What are your shader clocks ? Do you really need 1.6vgpu for 881 MHz ?

Nice work.

[wolfgang]

thats under phase an old mach1 that has been fixed up a bit. Samsung ram chip at 2.1. The core I dont understand it did not go over 35c 890 locked up on me twice at those volts

[largon]

Those "BL 121" chokes really get warm when clocks and vGPU are raised - I'm looking at 82ºC measured from the side of one of those buggers. Mosfet heatsink only reaches 65ºC so it really is the coils that are scorching down there.

[jason4207]

So, do you think it's advisable to throw some sinks on the chokes as well?

Hello,
Hello

I want to ask something:
(I'm noob on electronics so...)

This first picture on the first post was to do the vmod and vmem mod
I kinda understand

but what is the mod in the second picture?
using that 4 pins plug ?
is it just for connecting the 2 points or do I also have to plug it ?
what is it for ?

[/QUOTE]

[Zeus]

That 4 pin molex is just for measuring Vmem and Vgpu, you don't really need it, it's just for convenience.

[giorgos th.]

another one with single card on air with 1.35vgpu.

[Achill3uS]

my result after mods @ 1.4v all air



interesting, couse for 860mhz 1.3v is more than enough and on the other hand the memorys was stable at 1100mhz easy with stock cooler but now at 1050+ are unstable couse i don't use heatsink on them, so i need to solve this soon...

[Merkk]

another one with single card on air with 1.35vgpu.

your CPU makes a bulk of that score

[largon]

^Yeah, it's sad that 3DMark is just a CPUMark with 3D graphics.


FurMark is pretty much the only actual *3DMark*.

[aussie-revhead]

Is it more relevant to compare using 3D05 since it removes the score boost from having a quad core ? Guys still run 3D2001 and some 3D03 but 3D05 seems to be used least .

[mrcape]

Guys this thread is the nuts! Thanks for sharing. I have a BFG gts and hr-03gt coming in tomorrow.

[T_M]

Here's my OCP modded card (which im yet to test):

[jason4207]

T_M, do you have Samsung memory on that card?

[Bail_w]

hey, this is my first time to do a vmod on a video card, may i know where our fellow Americans order the trimmers from?

thanks

[VoodooProphetII]

Okay I need to ask a question. Now I got my GTS on water and load temps stay in the low 50's under load. I'm able to go up to 880core, 2150 shader and 1100 memory with 1.382Vgpu. Now the moment I try to go higher on the vgpu, say 1.390 or 1.4 I'll get frozen screens in 06 and 03, well to be honest in most of the 3d benchies. Could this be OCP kicking in. I know 1.390 sounds low from what I heard, but at 1.390Vgpu the load voltages will go as high as 1.48 to 1.5 in some of the benchies.

Not OCP. OCP would be a black screen. The added heat from the additional voltage may be causing lock-up. Once over 50*C you are on a fine line of stability at these high clocks/voltages.

Hi,

i'm thinking about buying the new gts.

does anybody know which cards have samsung rams?

the BFG i bought from newegg.com was samsung memory. i can do 820/1100/2035 on stock voltages.\

i see there are lots of options, but which one is recommended?

I like to use this website to search: http://www.alliedelec.com/

I like the way they show a pic while you search...makes it easier. But, I've heard they have a minimum purchase of like $25, but I can't confirm this.

Then you just take the part number and plug it into Mouser to get what you want.

Here's a list off of Allied: http://www.alliedelec.com/Catalog/In...513+4294912030

Just pick one that looks like it'll work best w/ the way you want to mount the device on the board.
