8800GTS 512Mb (G92) vMods

[Alex-Ro]

Nup,just at those frequencies it showed Gpu-Z.However i don't know to say,i will rerun that at the same freq to see what is going on.

Don't worry man, your 16K score might be legit, mine was just bugged.

Reran it and this came out:



Not to shabby for a dual core huh?

That is definately 19K with a quadcore.

[T_M]

Nothing bugged about anything Zeus.
Alex has two runs showing, one before at 15k and then a second run at 16k.
You have mistakenly used the GT scores from the 15k run in your calc, then compared the 15k result it gives to the second 16k run.

Now back on topic please.

Yeah, noticed that later.

How can one have 2 different scores?

Ontopic:

Did anyone with samsung memory have any succes vmodding it?

[T_M]

Two different scores is achieved by running 3Dmark once and getting a score, then rerunning without restarting 3DMark and getting your second score. Until you close the results window it doesnt go into the main window.

[giorgos th.]

also modded my GTS and put it in a small SS.here is with -20C idle,-5C load and 1.59Vgpu.

[Retratserif]

I am going to be purchasing a GT 512 shortly....

Of these available at Newegg.com 8800gt 512 List, which would in theory be better for overclocking and voltmodding. If that is even possible to distinguish.

I will be Watercooling, and Ramsinking each 8800gt I install. I will also keep 2 120mm fans actively cooling the ramsinks.

I am handy with a soldering iron and mods. Opinions, suggestions and criticism welcome. Hopefully not to much criticism.

Criticism: you are in the 8800 GTS volt mod thread, not in the GT one

Only advise I would give is to take a GT with reference board as it might be difficult for non reference board to find the good vmod.

giorgos - nice work , is that phase on cpu and vid card ?

[itou31]

Hi,

I've lower the Vmem from 2.05 to 1.946V and able to go from 1050 to 1100 stable (Qimonda ram). Thanks to Jason4207.

yes it is.a -40C for the 8500 and a -15-20C for the vga.

Always like to hear good news! Glad I could help.

You got any pics?

Props to Viper

Some fresh dutch air helped core and shaders but it seemed to have a negative effect on the mem or the mem is just loosing speed.

I suspect the contact between the memchips and the fullcoverblock wasn't as good due to coldness shrinking the materials, very little of course but enough to make contact slightly worse.

I have to remount the block with a bit more t.i.m. in between.


Nevertheless i had a nice run last night that puts some quadcore to shame.



Unfortunately the orb is a mess and i cannot submit this one.

[jason4207]

I also had a good run last night. This is 1.35v idle in 69*F ambient...all air!



Did a little recent remodeling inside the case as well.

[aussie-revhead]

Nice work guys , Im surprised to see my 17887 run still holds strong . Zues - those very highly clocked 45nm dual cores do run well dont they ?



Im retiring these parts to my 24/7 pc as I redesign my performance rig .

Yes they do but still they're nowhere near the performance of a quadcore.

As you can see i get my backside kicked by a lowly 3.8GHz clocked Kentsfield where i've got more GPU power.

For other benches these 45nm cpu's rock.

[ViperJohn]

Yes they do but still they're nowhere near the performance of a quadcore.

True but that is only in 3DM06 because it includes the CPU score in the overall score
and why it is worthless for anything more than relative compares on the same machine.

While I do agree having the CPU score in there keeps the overall score from reflecting current real-world gaming performance, it does help reflect overall computing power.

If games can ever fully utilize the extra cores then the overall score may have more gaming performance relevance. You can't fault Futuremark for thinking additional cores would be beneficial for gaming when they released '06...maybe one day they will be.

And you can always just look at the 3 individual scores to see if you have better gaming performance or encoding power (or both).

BTW: Thanks for all the help on the vmods VJ!

Can anyone provide some soldering tips? I successfully soldered my two wires to one outer leg and the middle leg on my 1K variable resistor. I tinned the other ends of the wires in preparation for soldering to the card. I first tried to solder the ground wire to a solder pad. The solder will melt, but it just won't stick to the solder pad. I'm using a 15W soldering iron and 60/40 solder.

Try practicing on something besides your $300 gfx card.

The solder pad has to melt as well for the 2 objects to fuse. Make sure the area has been cleaned well w/ 90+% alcohol, and putting some flux on the area can help as well. When soldering you aren't trying to make anything 'stick'. You have to make the 2 objects into 1. The solder on both pieces has to melt for this to happen. If the solder pad is connected to a large area (this happens a lot w/ ground connections) then the heat can be wicked away very quickly from the area your trying to melt. You may have to hold the iron on that area for longer than other areas. Which spot are you trying to solder to? Perhaps a better ground location can be used.

Not enough heat. A 15w iron it to small especially when iron plated tips are used.

Hey all

My old GTS died (R.I.P.)
Don't know why

But RMA was successful
New GTS has SAMSUNG memory.





Memory OC (no Vmod) to 1210 for bech and 1160 24/7.
-GPU/shaders 890/2133 1.33V 24/7
-GPU/shaders 920/2250 1.45v bench (for now)
