so who is going to be the first one to move that 3 pin jumper??? lol, not me, but i sure am curious to know if it will bump the voltage or not.having two BIOS would be interesting when something goes wrong after flashing,
and by moving the jumper you can boot up with a working BIOS.
Default vcore is 1.05v,
and the highest factory overvolted 8800gt is the evga ssc at 1.1v,
so in case that jumper is working, I assume it will increase 0.5v, which is enough to reach a decent OC.
good luck, and definately let us know the results!I'm moving mine before I install tomorrow.
Just wanted to let everyone know that the radial fins on the galaxy 8800gt extend into the region devoted to the power supply for the aspire / apevia X-Qpack and all microfly wariations. I am not going to RMA the card, rather I am now starting to look at my options for better designed case where the PSU isn t directly on top of the video cards. I am away from home (merry xmas) but I just wanted to let everyone know that while the galaxy 8800gt is as awesome as the second coming of christ, it does not fit in the Qpack / microfly. I will take pics as a reference when I am back home.
mine has the Qimondo, and it's 1.0ns which = 2000mhz. the Samsung is 1.2ns which is rated at 1800mhz.do you have the "coolermaster" version with Samsung memory?? wow!!
Best ram for OC, way better than Qimonda !!
and no way we can reach 770 at 1.05v, the jumper must be adding those extra 0.5v
the cards i saw in a review that where oc'ed out of the factory to 2000mhz had the samsung 1.2ns memory. imo that explains why most people that bought those cards had to underclock them to factory specs. now, they should have used the same memory as mine, then they couild handle that clock speed. someone screwed up somewhere along the line!are you sure the Samsung memory is 1.2ns ?
I'm confused, is there a version with the CoolerMaster cooler with Samsung memory and factory overclocked?
Gautama >>
do you have this version of the card with Samsumg vram?
and it has sammy ram @ 1.2ns?No, didn't bother. Too little of a performance gain to be worth my time.
Like I said, however, mine came stock at 2ghz not 1.8ghz
think the better mem overclock is the cards with Qimondo 1.0ns, which are the cards with the cooler master heatsink. i dont think any of the one that are clocked @ 2000 on mem have have Qimondo, which "they" are the ones that should have the 1.0ns mem.At first when this card showed up at NCIX, the reviews from users were not so good about vram overclocking. Even Galaxy used Qimonda 1.0ns, it was difficult to reach 2000Mhz.
Now, there are a few examples of people reaching higher overclocks, around 2100 - 2200,
and the only difference so far is the vram manufacturer, Qimonda and Samsung.
I was trying to make a list with oc results for both vram chips.
Are the higher oc results reached with Samsung memory?
I'm pretty sure my temps confirm it.
Try just switching the jumper without changing your clocks. Clock speeds also increase temps (although I don't think to that degree), but it would be something else to check out. Anyway, very interesting card Galaxy has put out, looks like a real keeper .I'm pretty sure my temps confirm it.

hmmm, kinda sounds like it does indeed up the voltage then. now, i wonder by how much ...Can't stabley get to the same clocks without the jumper moved.
cool. looking forward to your findings!Nice to see the jumper actually works.
Could you check if your Samsung vram is 1.0 or 1.2ns?
The voltage increase should be of 0.5 which can be reached by simply modifying the BIOS
Anything higher is only reached by hardmods.
I just asked at xtremesystems how to measure vcore with a multimeter in this PCB,
as soon as my card arrives I'll check the voltage increase.
