No sinks at all ? Not extra chipset etc ?
I look forward to buying one of these .
:up:
Does anyone know what the jumper looking thing at the back of the card near the power connector is for?
I am just to tempted to place a jumper on it :p: .
haha no team-eva it's Team AU = http://teamau.i4memory.com/ and http://teamau.i4memory.com/1 :)
Nah mate I meant i4 in general not team-au :rolleyes:
ie your group = i4 = team-eva
:D
As soon as money comes through from my GTX sale I will be off to grab a 512 GTS . Then off to Jaycar to get some more VR's ...
:up:
No sinks, and there is no extra chipset either.
I've checked the qimonda 1.4ns datasheet but i can't find all the values that nibitor is showing me.Quote:

I've got to change all the timming sets ???
Could you share the vmem mod for lowering the vmem value ?
No, only change the value in timing set 1.

Hey all,
I must have read this thread 4 times and am very interested in vmodding my G92 8800GTS, but there's only one problem: I've never done a Vmod before :eek:! I have a 15W iron and some thin rosin core solder. I also have some 22 gauge solid copper wire, but I think I might use some fan wire (seems like its thinner, 24 gauge+) instead. I did some practice work on an old PCI 56K modem just to get some PCB work under my belt, but I'm still a little wary of the exact procedure. I also ordered some 200, 500, and 1K ohm trimmers that look very similar to the ones T_M used in the first post. Anyway, can anyone throw some hints/tips for a newbie my way, or are there any good guides around? Thanks for all the information already and the great read :up:
Changed timmingset 0 or 1 ?Quote:

How about in one post pics of all the mods?
Vgpu, vmem, ocp, ovp ???
Lots of information in different thread... 8800gts, 8800gt, g80 :confused:
Thks!
On my EVGA the Vgpu mod yields a max of 1.52v on AIR with stock modded heatsink....I will not do the memory the Qimonda dosnt run like my samsung did on the 320...The samsung would run 2300mhz 1.210 no prob! the Q onlydoes 2250max @50c ...It not worth the risk untill they decide to use better memory...Also @ 918//2268//2250 the bandwidth sucks....256bit bus shows little improvement when overclocked past 808//2000//2250...
Note:Ovp kicks in @1.53v on this card with Air
808//2000//2250 = 3Dmark06 13090 points @3.48ghzX2
918//2268//2250 = 3Dmark06 13200 points @3.48ghzX2
Overall the Max SM 2.0 =6150 Overclocked
Overall the Max SM 3.0 =6700 Overclocked
The GPU and Shader helped the SM 3.0 score by 1000points over stock score of 5600!
Having a high Oc on the memory is a must,, This is what helps the SM 2.0 score the most along with the Extra 10bw gained in the band width department:shakes: ..
SM 2.0 Stock was 5300 and Overclocked gained 850 points..Since the The memory dosnt do anything more over 2250mhz im not messing with the Vmod for it...Ive ran the memory @2300mhz but it would fail half way through any test...Temps were 50c max load running anything!
In short the Vmod will get you 918mhz GPU and 2300mhz Shader easy..But with 1.5v-1.525 before the Prtection kicks in on Air!
If some one is using water id like to see results of this with out Chilled Water..
I may throw on a water block and go further ,but am still testing this thing on Air...
This thread has been Very help full,, Solder points are the easiest by far.
Keep up the good work :up:
On a Quad this would easily get 2000-3000points more @3.7-4.0ghz So i guess im happy...No X2's come close to 16000 even @3.5-3.7ghz:down:

Please can you test by running GT2 in 3DMark'06 (Firefly) and tell me at what idle voltage does your OCP kick in?
Im sorry ,,I think when it had crashed the first time i was ajusting during bench and went too much:D The Volts jumped past 1.6v when it had shut down...Its safe to say That OVP is 1.6v or higher! My card is freezing the screen @ 1.576v loaded..So it may be heat related..Which sucks because Riva reports a max of 51c when i bench this high! Idle is @37c when cranked to 920mhz! If you look in my Screen ,, my temp was about 42c max here then about a few minutes later i aborted from a freezing screen...Quote:

so this is what i just did...I loaded3Dmark06 started bench @907mhz
Idle 1.52v
load 1.576v
it benched!
So then
Idle 1.53v
Load 1.59v-1.60v
Froze screen...So i may be shutting down due to Core?
i remeber that i had a Full Pc reboot @1.525v during a bench last night...i was shure that was from the OVP...
Hope this helps..was done with memory @ stock clocks too!

I'm on vista64 and the autodetect on vista64 doesn't works...already mencioned on mvktech forums...Quote:

I edited the timmingset 1 but if someone could test the autodetect to just make sure :up:
Still looking for mod to lower vmem
Thks!
HAPPY NEW YEAR everyone !!!!
(well its 1.20am 1st January here)
Have you guys found a particular nv driver works best with these ? I found 169.09 worked best with my GTx but this version doesnt recognise my GTS . I also had a similar problem with the newest 169.28 drivers , what are you guys using ? I got my rig to 16,050 at 3.9ghz , but it should be capable of more . Is there much to be gained by altering timings with nibitor ?
What sort of core clocks can I expect with volt mod on water ?
Any help would be great.
:up:
Well seems to me that the vmem on my 8800gts 512 should be different than the generic.
Why?
Look at the ic at the back of my card ...
http://img108.imageshack.us/img108/8...0092ny8.th.jpg
Already googled but no luck :(
Any info would be great ;)
Got to discover if my mem's are from qimonda too, to see if the mod should be lowering the vmem or not :cool: .
But i guess they should be qimonda...anyone with a 8800gts 512 from gigabyte to confirm this ?
found one guy with a 7100gs with that ic but no luck too i guess -http://forums.vr-zone.com/showthread.php?t=183215
I have also the same gigabyte board and the timingset is No 1 .Quote:

Is your card modded ?
To be honest , i don't remember . I didn't bother to check it ... and now it's difficult to see it cause i have to remove the card .Quote:

What is the "standard vmem ic" ??? Do you mean the ISL6549CBZ ??? All G92 cards are supposed to have the same IC . Maybe it's relabelled .
Increasing vmem give you higher mhz on your gigabyte ?Quote:

Maybe relabelled cuzz the reference is completely different as i shown 4 posts back.
Your card is just Vgpu/vmem modded ?
Which clock are you reaching? Cooling?
Thks again ;)
I have only tried to lower the vmem . Right now it's at 1.92v .I got the mod from jason4207 via PM , but i haven't asked him if i can publish it . The best way is to send him a PM for information . I don't either like this "secret" mod , but it's not my choice since it wasn't me who found it .Quote:

Yesterday i put some heatsinks at the voltage regulators (they were very very hot) ... no time to check for gains .
