Maybe someone on here could explain it to me better, is there a reason why they can only double the memory on these cards? Why cant they add another 256 megs or half a gig instead of doubling it?Quote:

For example in the Radeon HD 58xx the GPU has a bit-width to the on board
memory of 256. In order to reach 256 bits you need 8 memory chips (8 times 32).
The size of memory chips comes in multiples of 2, thereof the doubling each time
you move up in memory size.
@ Kej
Thanks for the explanation, is there a way around this design wise or are they stuck at doubling up?
the bitrate determines the number of chips, so 32bit per chip / 256bit bus = 8 ram chips for a 5870, if they put on a 384 bit bus, it would be 12 chips, and be 1.5GB, its very possible, but would add more heat and use up more space, and is needed for bigger chips, or for using slower chips, like the 480 uses.Quote:

going much higher than that is probably a bad idea though, the 2900 was 512bit and power hungry, and had a bandwidth of over 100GB/s, and was never really used effectively.
Thanks Manic, it certainly is good to learn the tech behind those fps
warning, i only know what i learned on here, lol. i actually have no real job experience with computers, or any classes for computers, all self taught, or learned from the guys on here.Quote:

Too bad no voltage adjustment with the retail card, 1.3V should do wonders!
-1 doesnt even look like the batmobile..
whoa this was my 555th post :D
No voltage adjustment? How about that Gigabyte OC utility to ajust vgpu and vmem?Quote:

not sure yet - might be that I was doing something wrong. But vcore mod is super easy - just moving some resistors around for a vid mod. Will try that later tonight - hopefully 1100+ on air. But I am confident it a modest boost it should at least do 1100...Quote:

Mine is now in Leipzig, wuhuu, now less then 1K miles from destination!

Removing the card again to re-apply thermal paste and I'll give it a quick OC test on air before I start insulating it.
Cool Bench!! Looking forward to this......hope you check out the Ocing software as well.
Actually I'm currently looking for it :p:
My card arrived in a foam box ( no accessories, package, CD ) and every single Gigabyte contact of mine is off-line or away :p:
Maybe our humorous Australian buddy has it ? ( he must be sleeping now though :( )
I will have to check the CD when I get home but I am reasonably sure the card does ship with the SOC Tuner.
what a bunch of babies, back in the day if you wanted more volts you had to get out the soldering iron!
Considering it sounds like a promo card from Gigabyte & probably has to be returned, soldering on it probably isn't a great idea. First you see what the card can do on air & use the software....then go cold & really use the software....... & one more thing, For those of us buying our gear, people don't want to buy a second hand card that has been modded.
Yup, the Ozzie is down...or pulling an all nighter, but Mike G has a card.
Seems that Mike is right the SOC Tuner will not raise voltages. First who post the hardmod wins a prize :up:
WOW! Total fail :confused: :down: :shakes:Quote:
