the highest you reached with 6800GT @ "normal" cooling (air, water - NOT phase, etc.)

**p4z1f1st** · 01-08-2005, 06:22 AM

so guys....i'll sell my AGP-6800Ultra and want to settle on a SLI-system....but i won't buy 2x 6800Ultra's but 2x 6800GT's

so, i'll cool both cards with water....and mod the BIOS' to 1.5V VGPU

but i only know, what's the average-oc'ing of ultras....could you all guys who has a 6800GT tell me, how far you can go 100% stable (not benchstable - i mean, when you can play f.e. FarCry forever

) on water (air-results are OK, too)

i just want to estimate, how far i'll probably go

**MrQ3W** · 01-08-2005, 06:35 AM

Wondering the same, which brand is the way to go also.

**JasonDTM** · 01-08-2005, 08:15 AM

If gainward had some PCI-E Golden Samples out, those would be the cream of the crop, and as you prolly know, a GT at Ultra speeds is faster, I think XFX has some PCI-E 6800's and a few other manafactures

I read someplace that it was the bios that made the GT faster than the Ultra at the same clocks, maybe try a GT bios with the ultra? If I recall correctly it improves 3dmark05 by like 150pts, nothing to sneeze at for a bios flash

**Playful_Buffalo** · 01-08-2005, 10:34 AM

i run 422/1150----- 24/7 on my EVGA 6800gt (stock cooling, stock everything)

the only additional cooling is two Smartfan II's blowing at it (one temp probed, one i adjust)

The GT is faster at Ultra speeds due to the memory timings, but the Ultra has more overhead to overclock ect.

**p4z1f1st** · 01-08-2005, 11:16 AM

guys, until now, just Playful_Buffalo answered my question like i wanted to

btw Playful_Buffalo: what's that for a chick as your avatar?

Anyone have any idea what the different timings are between the Ultra and GT?? Cause you can edit the timings in Omni right?

I don't think so, its always greyed out for me

Yep your right, greyed out for me also.

**MrQ3W** · 01-09-2005, 07:13 AM

Read what the author of the topic said, he wants to know clocks of 6800 GT not discuss modding Ultra BIOS. I suggest you follow his wishes or go to another thread if you cannot respect that.

I can get 417/1150 but that's with BFG's kinda small single slot air cooler.

**XTCgr** · 01-10-2005, 01:21 AM

430/1100 for 24/7 (performance 3D) watercooled GPU and 1.4vGPU . I havent tried to check stability for everyday use above 430mhz but i think it can go further since card is benchable up to 460 with 1.4vGPU

Edit : Gainward 6800GT (not golden sample)

**IvanAndreevich** · 01-10-2005, 01:37 AM

The BFG I temporarily have is very weird. IE - after flashing 1.4V to it, this is what happens:

1) 3DMark2005 @ 420 MHz loop 1 hour = no problems. Performance increases accordingly.
2) 3DMark2001 @ 415 MHz _INSTANT_ hard-lock of the system.

This is with NV5 Silencer. I need to get some thinner bolts to mount my watercooling on it. This week

**PhonyEye** · 01-10-2005, 01:39 AM

Point of view 6800gt 256mb - running on 401/1150 24/7 on stock cooling. temps are 53c idle and 65c on load

**xs64** · 01-10-2005, 02:17 AM

Gainward 6800GT AGP8X ( not GS ) @ 420/1150 1.4v stock cooling , 65'C full load running everyday

**jikdoc** · 01-10-2005, 03:23 AM

fastest on air i got a 6800 was 415/1100. this was stable for most games except hl2. with the gainward gs bios i gained ~70pts on 3dm05. i've had strange problems with 1.4v bios mod on my bfg card. with the 1.4v bios mod, i have a similar problem, will run through 3dm05 but locks on 3dm01 & games. only thing i can think of is possibly psu related. my system is near the max for my ocz520, i think under high cpu stress, there's not enough watts for the gfx card @ 1.4 and hence the lockup. the explanation could be simpler though, i read in a post on another forum that some of the newer (read this in october) 6800gt's can't handle 1.4v as well as their predecessors, possibly related to overheating of mosfets and/or lack of a 2nd molex which the ultras have.

**funkflix** · 01-10-2005, 03:35 AM

430/1250 MHz. Watercooled and flashed to 1.4V.

**Jupiler** · 01-10-2005, 04:28 AM

POV 6800GT, running 400/1100 for daily use (flashed to 1.4V).

**thomas66** · 01-10-2005, 06:16 AM

pny 6800gt no mods / stock cooling

can do 405/1130 forever ( benching sweet spot 410/1150)
i run it at 400/1100 just looks better

**Garrett** · 01-10-2005, 03:01 PM

XFX 6800GT @ nv5 silencer @ 420/1150 24/7 usage

original bios still in it (1.3v)

Wimo · 01-10-2005, 03:05 PM

Point of view 6800GT 428/1140 24/7 stock cooler, stock voltage

Giving it 1.4v only adds throttling ... I need a waterblock! With 1.5v this thing could fly

**sky** · 01-10-2005, 03:18 PM

pov 6800gt bench at 410/1151 given enough air she'll do that in games. i use a slightly modded default heatsink (single slot). removed the fan and replaced it with a former coolermaster hhc-01 fan plugged into the nb-socket (running 8v). at 12v it handles the load just fine. anything post 410ish is not really stable. either lower mem and run 420 or keep it there...

**drcrawn** · 01-10-2005, 05:04 PM

Here my stable gaming speeds right now with watercooling, single 6800 Ultra. 1.5v.
