Despite being OC'd to the hilt I'm only getting twice the speed of my "old" GT240's anyone know why. I must admit I was expecting more.

Thanks SK wish I'd known that before. It's one thing after another today. If disappointment were a star sign I would have been born under it.

Basically only 2/3 of the shaders are usable on GTX460s, the GTS450 and other cards with the same architecture, with the current ACEMD based apps. I have no idea if this can ever be fixed, but I suspect it will not be available until a new ACEMD release, if at all. The top end cards (GTX580, 570, 480, 470 and 465) do not suffer from this architecture problem. It only impacts on GPUGrid, not other projects, because only GPUGrid uses the ACEMD program, required for molecular dynamics research.

I think there was too much hope for these cards, including the GTX560 (same architectural flaws). The only benefit over a GTX260-216 is that it uses less electric.

Hola: Una cuestión que no veo se comente es referente al rendimiento de la GPU es la PRIORIDAD de PROCESO, en Windows suele ser "Menos de lo Normal" y en Linux (10= Muy Baja).

En Linux pasando de una Prioridad de nivel 10 (que es la asignada automáticamente por GPUGRID) a una nivel 5 (Baja) al aumentar en uso de la GPU, el tiempo de ejecución de por ejemplo IBUCH pasa de 10H a unas 8H aproximadamente (GTX295).
En Windows pasando de "Menos de lo Normal" a "Normal" pasamos de un uso de la GPU del 50-60% al 70-75% con la mejora de tiempos de procesado.

Evidentemente aumenta el consumo y la temperatura. Saludos.

i'm still hoping for the new app that is scheduled for mid february, which should improve performance and usage :)

Hola: Creo que sería interesante que se publicara una estadística de rendimiento "real" tomando como base los tiempos de las tareas realizadas registrados en la cuenta de cada uno, según la GPU usada, en especial las series nuevas GTX500 y 400 y la anterior serie GTX200.

Es una buena guía para la compra de las futuras GPU. Saludos.

Ingles: Hi, I think it would be interesting to publish performance statistics "real" basis of times recorded tasks performed in each account, depending on the GPU used, especially the new GTX500 and 400 series and previous series GTX200.

It is a good guide for the purchase of future GPU. Greetings.

i have another problem :)
i now have 90% constant gpu usage on a task but it causes severe freeze on my computer and i am forced to suspend it.

this is a picture of the gpu task: http://oi56.tinypic.com/8zlj5d.jpg

advices?

Use this tool to change the priority of acemdlong_6.14_windows_intelx86__cuda31 to "normal", or "below normal". You should put a shortcut of this tool to the start menu's startup folder to make it run at every system start.

thanks to all the users that replied to me in this thread
