8800GT in my rig

[LuckyNV]

I'm itching to get one of these things overvolted and watercooled! :P
But I hope the power regs don't get screwy at >>700MHz...

FUGGER,
Have you yet peeked under the HSF?
I'd be interested in the power regulation. Is it 2-phase or 3-phase on your card? The PCB actually does allow 3-phase, like VR-Zone's review card which has empty pads for a 3rd choke plus a pack of FETs and caps:

anyone know which bits there have contact with the stock heatsink?

[Charles Wirth]

Cozwin, might be possible. Waiting on bios atm.

I can squeeze a bit more out of this card. One of the things I do is re-torque each screw making sure the core is as tight as possible without breaking it. Make sure you have the right screw driver to prevent damage or dont do it at all. I have not taken the heat sink off.

SLI on intel chipset? i want one

7900GS vs 8800GT



the GPU is sooo big compared to 7900GS, so i need a vmod anyone has done it?

[largon]

metro.cl,
vGPU and vMEM mods should be quite similar to those on 8800GTS/GTX, macro shots of the areas highlighted in the jpg attached to this post would help to pinpoint the exact soldering locations.

The rectangular chip should be labeled:
Primarion
PX3540BDSG

[dinos22]

DO NOT USE THIS IMAGE

will update proper one soon

[largon]

Thanks, dinos22.
Need clarification on the existence of certain traces and few resistance measurements, see attachements.

First pic:
There should be traces between points 1, 2 and 3. It certainly does look like there is a trace between 2 and 3, but is there one between 1 and 2? = if there are traces between 1, 2 and 3 then resistance between each is ~4-6Ω.
Also,
Resistance between points 2 and 4? (might be <10Ω)

Second pic:
Resistance between points 5 and 6? (might be around 500Ω)

[Eagleclaw]

All those screws on the back need to come off for the heat sync removal? Anything else?

What cooler are you putting on it, I have the Fatal1ty sitting here for my card, should be here today and I am putting the cooler on it right away.

[dinos22]

largon that image was from nvidia FTP

i just looked at my card and it looks a bit different so i took it DOWN for now

and will upload my macros

also can you measure resistance with card not turned on (pretty sure yes) and also how the hell do you measure it hahaha

[cowie]

with your ddm just measure
black on one side of resister and red to other side

[dinos22]

that i know

which nob is for resistance though sorry noob with this kinda stuff

"the GPU is sooo big compared to 7900GS"

the ihs u mean is bigger?the 7900gs is naked and has the bigger die.


"Thanks to a die shrink to 90nm, the G71 GPU on the 7900 GT was able to deliver the same basic technology and performance as the 7800 GTX while running cooler and costing less to produce."

"Well, the 8800GT is 65nm instead of 90nm. Smaller die size might have dropped the cost quite a bit. And who knows what ATI has coming. ..."

so its a bigger ihs with a SMALLER die 90nm(g71-g80) shrunk down to 65nm(g92)..i honestly belive naked gpus run way cooler.wish my gtx was naked.


sorry fugger,was telling him die shrunk..

Both are naked.

might be possible crossfire is working on different mobos now inc nvidia chips so maybe, but im sure 2 of these and a 45 nm cpu and a nice sli mobo could probs take world record for 3dmark06

[Charles Wirth]

I ran the Crysis bench, 1680x1050 custom settings, I will re-run with high and very high detail.

Crysis for me run good with the video card at stock.

GPU/CPU

[hixie]

All stock settings with E6850, at resolution 1024X768.
More than what a 8800GTS scores

You know you could always take off the heatsink and see what happens.
Honestly i don't see how a naked GPU would be cooler than one with a good heatsink and thermal compound.

Just like a naked CPU runs hotter than one with a heatsink and good thermal compound. Metal just conducts heat better than air thus you can move heat way from the source faster.

Now back to the topic, I can't wait to get my hands on one of these. I plan on seeing how far i can push it before it breaks. Can anyone tell me how hot does this card usually get at stock?

silly boy
he is refering to a naked DIE like the 7800/7900/8800GT use vs. the 8800 GTS/GTX which uses an IHS to cover the die like your cpu does.

an IHS leaves too much room for heat gaps between the die and the IHS.
thus that is why you see people taking the IHS off their cpu's. in general your only going to get 5 deg better temps but there are extreme cases where i have seen twice that in a temp drop.

Oh, thank you for the explanation. That could indeed be better for temps

Nicely done Charles

Last night I was playing around trying to get some sort of result out of my cards after two previous nights of wasted benching time and motherboard horrors with beta BIOSes trying to get something stable with the Yorkfield + high FSB.

Everything came crashing apart night before last when the GA-X38T-DQ6 went out with a pop and it's soul puffed out into the surrounding atmosphere.

So last night, pissed off and just wanting results, I swapped in the GA-X38-DQ6 with the F5h BIOS loaded and cranked the multiplier just to get something happening with this setup. Here's what happened:


System:

Intel Core 2 Extreme QX9650 @ 4.66GHz cooled by Frozen SS phase cooler
GIGABYTE GA-X38-DQ6 with BIOS F5h
Corsair Dominator PC2-10000 @ 533MHz (DDR2-1066) 4-4-4-4
NVIDIA reference 8800GT @ 760/1701/1025 (2050 effective) with stock cooling and 169.01 drivers
Silverstone OP1000 PSU
Western Digital Raptor-X HDD

3DMark06 result: 16,357



HWBot compare link: http://www.hwbot.org/result.do?resultId=661269
HWBot profile: http://www.hwbot.org/user.do?userId=11510

Casualties:

1x GA-X38T-DQ6 replaced with GA-X38-DQ6



After getting angry with having no results the platform was moved to the GA-X38-DQ6. Further wanting to simply get results, I avoided the annoyance of FSB overclocking and instability and just cranked the multiplier for some quick results. The memory and general bandwidth of this sytem is quite low for this reason.

There is a lot of efficiency and general extra speed to be gained from this setup. Next step is to get some volt mods happening and get some dry ice on these cards - they're great fun

Due to currently being on deadline at work (AtomicMPC magazine) I hadn't a chance until just now to see these results and had thought I'd scored myself a WR but you certainly showed me up mate

Hopefully I'll get another chance with the gear over the weekend and can get some decent FSB and memory frequencies happening.

BTW, what BIOS did you run on the P5E3 Deluxe? I got the 0508 BIOS earlier in the week but am yet to test it. If it's a winner I'll make a swap to that board for weekend benching with a set of Patriot PC3-15000 modules or the Corsair PC3-14400 that just arrived an hour ago

SM3 seems very low. I'm getting 100point more even on stock ultra frequence with 1 year old GTX mod to ultra. It's strange 150mhz more on GPU and 200 more on Shaders with 600mhz more on CPU and 50&#37; more cache to give you such a low SM3 result

Hey fugger, how is the noise of the HSF?

I'm a little disappointed it ain't a dual slot HSF, but it probably doesn't need it because it runs so cool.

My main concern is that the little fan supposedly causes an annoying high pitch whine when it spins up - do you notice this?

[Charles Wirth]

I cant hear it while gaming. My Vapo is louder.

Not bad Josh, 0503 bios still.
