Então colocaram lá aqueles chips underclocked só para dizer que os chips overclocam depois muito não??É que de certeza que são mais caros que os 2.1Ghz
Então dá aí um link para uns screens onde ele troque os timmings.
Opa lá.
Já são 3 posts teus a dizer isso e links para provas concretas, nem vê-los.
BTW, por muito melhorados que sejam os timmings da memória GDDR4, serão sempre piores do que GDDR3 à mesma velocidade (i.e., 8800 Ultra).
É o "trade-off" para conseguir velocidades mais elevadas.
16 chips GDDR4 a 2.2GHz de certeza que são mais caros do que 12 chips GDDR3 a 2.2GHz...
Estava-me a referir à 2900 que tem os chips underated DJ_PAPA tem mais memória mas de certeza que 16 são mais caros que 12 chips16 chips GDDR4 a 2.2GHz de certeza que são mais caros do que 12 chips GDDR3 a 2.2GHz...

0.9ns equivale a 2200MHz.
Penso que cada décima equiva-la a 200Mhz 1.0ns=2000Mhz 0.9ns=2200Mhz
Currently the world's fastest memory-Samsung 0.7ns memory. The maximum nominal frequency as high as 2,860 MHz, very tough, Ling Tung and Radeon 2600XT even mix HD 512 M GDDR4 memory, both performance and overclocking ability or great potentials of space.
http://www.theinquirer.net/default.aspx?article=40378OCUK, THE WELL-KNOWN UK e-tailer began accepting pre-orders for the 1GB HD2900XT card, with availability coming within 10 days time, as we said here and here.
There are several minor changes to the board, but first and foremost, the clock of the memory has risen from 826MHz DDR to a clear 1GHz mark, a nice 17% increase. The bandwidth rose to a record 128 GB/s, from 105.98 GB/s on a 512MB card. The PCB is give or take identical, with 16 el cheapo Hynix memory chips being replaced with 16 spankin' new Samsung GDDR-4 chips.
We're not sure about the overclockability of the memory chips, but the GPU is known to clock by 100MHz or more on stock air cooling, and a 200MHz overclock is easily do-able with water-cooling. We're currently experimenting with Italian waterblocks by Ybris, and our 512MB boards are happily working at 1GHz, a hefty 248 MHz up from default clock.
For those that do not find regular 512MB R600 attractive enough...
Given the headroom given by this 80nm GPU, we are surprised to hear that GPU clock remained the same on 1GB card. So, 79 quids more for 512MB memory more, and nice 22 GB/s increase in memory bandwidth, which should boast scores when advanced filtering is applied. µ
btw, como é que fazes essa conversão ?
Mas achas que esta bate a GTX??
