there's a CPU bragging thread, but not a GPU one? i find overclocking my GPU more interesting and fun that my CPU, because it's never a one-step solution; and generally you can't just buy the best heatsink and be done with it. it requires more dirty work. enough with that though, braggin time ;)

i'm sittin pretty on this one, i've got an eVGA geforce fx 5900 ultra flashed to an fx5950u with a core of 620mhz and memory of 1022mhz, artifact free. the only problem is that i'm having trouble with fill rates :S also i get some artifacting in 3dmark03. i can make them go away mostly by lowering the memory; but i keep these speeds because i play games just fine with them (doom3 in particular).

i did it with a homemade 2-fan bracket sitting adjacent to the card, blowing on it at a 90 degree angle. there are ramsinks on the ram, and an intelcu rack server copper heatsink on it. it's got an OEM 80mm amd heatsink fan blowing on it. i'm volt limited, so once i can find the proper tools i plan on volt modding it with my own volt mod. i will post the tutorial on it should i actually get the equipment and/or balls to do it.

I've got an ATI 9600xt runnin fine at 574/351. Anyone know if upping the agp voltage will get you more mhz?

Thats with copper ramsinks and stock gpu cooling!

i would go against this. you should never change the voltage on an agp card. it may shorten the life of the card, which i dont think you would want to do. anything above the stock 1.5v is unhealthy for the card.

i get the temps of 32C idle, and approx 45C full load, give or take about 3-5C depending on the room temperature. the only thing i've got right now for pictures is a shitty webcam :( will take pictures with it sometime though.

that is a tricky question. first it depends on the method of upping the volts. if you can get a new bios that bumps the volts some, that is a lot safer than an actual physical voltmod of the card. with stock gpu cooling, i wouldn't reccomend it. the ram is really unaffected by the voltages, it's your core that can really benefit from a jump in volts. the only way to tell tbh if it's volts that you need is if you've fooled around with it enough and are experienced enough (no offense or anything) to tell if you need volts or not. there's 3 things that can be holding you back. first it's cooling, you increase the cooling you can make the card overclock more. next is voltage... once you've cooled it so that no matter how much more you decide to cool it, it's not gonna overclock anymore (perfect example being when i changed from a 60mm fan to an 80mm fan on this card... it took my temps down on idle 8C and even more under load, yet i only got 2 more mhz out of it, i plan to resolve this later, lol)... then is when you know you're voltage limited. sometimes it just requires the proper balance. updating the bios of my 5900u to a 5950u gave my card .1v's to the core, which really improved its overclock (around 450 before, around 580 after). the last thing is the absolute limit of the core. doesn't matter if you've got all the cooling in the world and all the volts in the world pumped through your core, it does have a maximum limit, if you hit it (usually quite hard to do, depending on the "headroom" of the hardware), then there's nothing you can do to go any faster but get a different core.

My 5900 was at 450/920 with ASV.
My 6800GT is at 380/1.1Ghz with ASV on the GPU.

AS was the only "mod" that was done.. I suppose some water would be nice.
But pulling 11k in 03 is good enough for now.

Btw Kamel, that looks frik'n tight. :wink:

Hardmod with a pencil (connected the lasercut bridge), still 12 pipelines. Flashed with Gigabyte's flasher, rebooted, and VOILA!...

X800 XT Platinum Edition :). (had to reflash using an ATI X800 XT Bios, VIVO features weren't working.

Running at 560 core 580 RAM (1160 DDR). Anything higher and it's either artifacts or system crash.

I'll put ramsinks on RAM and use a beefier Heatsink.

Getting some serious 3dMarks (if I remember, it's around 12,000 in 3Dmark 03) (running on overclocked Mobile Athlon 2500+ @ 2.4 Ghz)

DooM3 runs smooth now compared to my old 8500DV.

does this mean that the x800pro is actually worthy of its hefty price tag? (after hardmod)

Any kind of overclocking is dangerous. Upping the voltage is required for any kind of serious oc, though ... it is a danger you have to weigh when deciding whether or not to oc.

Personally, I wouldn't up the voltage unless I had some serious cooling on the GPU and the ram ... which is why I'm investing in watercooling setup. Well, that and the fact that I'm sick of hearing my hsf whine under load. :?

what are some really good HSF for video cards? i know there are the artic cooling one but does thermaltake or thermalright make VGA coolers?

Ran 3DMark05 looked for Artifacts and this was as high as I can go w/o any visual problems.

Had my old GeForce 3 overclocked for a year w/ no problems.

Alright, I'll throw in my 6800 Ultra clocking result.

510/1320 with an Innovatek NV40 Cooler (watercooling). Works great mated to my P4 SL7KC 3.4 @ 4.2.

Runs 15,629 on 3DMark03.

And my old GT, on air, 470/1140 with my old P4 3.2 @ 3.9.

Ran 14,300 on 3DMark03

I just got a sapphire x800 xt pe , and running at 580core/590ram, so far with 40c load temps using a waterblock, its in the circuit after my cpu and chipset. I am going to put on ramsinks tonight and try for higher ram speeds, (although they run kinda cool compared to my 9800pro ram) the gpu wont go past 580, it just freezes but no artifacts at all up to there.
