O simpla intrebare la care multi nu reusesc sa afle raspunsul.

Daca cumpar o placa video ATI Radeon cu pci-express 2.1 si o pun pe o placa de baza cu pci-express 2.0 Va merge ?
Am cautat pe internet o zi intreaga, multi nu pot sa raspunda la intrebarea asta sau incep si se contrazic.
Daca voi stiti raspunsul si aveti si o dovada plauzibila va rog spuneti-mi si mie.

Ar trebui sa mearga pentru ca placile video sunt backward compatible pentru versiunile mai vechi de pci express si in plus nu sunt diferente mari intre cele doua versiuni. Cand am achizitonat prima data un HD4850 avea versiunea 2.0 dar a mers fara probleme pe o blaca de baza cu PCI-e 1.0.

Multumesc foarte mult pentru raspuns, am o placa de baza http://www.gigabyte.com/products/product-page.aspx?pid=2960#sp si vreau sa iau placa video de la ati http://www.pcgarage.ro/placi-video/gigabyte/radeon-hd5770-ultra-durable-1gb-ddr5-128-bit/ .
Sunt sigur ca o sa mearga.

Va merge, n-are treaba. Placa mea de baza are 2.0 : http://www.pcgarage.ro/placi-de-baza/msi/k9a2-platinum/

Si placa video are 2.1 : http://www.pcgarage.ro/placi-video/sapphire/radeon-hd5870-1gb-ddr5-256-bit-hdmi/

Si merg foarte bine. -

Eu as merge pe placa asta video : http://www.pcgarage.ro/placi-video/gigabyte/radeon-hd5770-super-oc-1gb-ddr5-128-bit/ sau http://www.pcgarage.ro/placi-video/sapphire/radeon-hd5770-flex-1gb-ddr5-128-bit/ sauuu http://www.pcgarage.ro/placi-video/gigabyte/geforce-gts-450-oc-1gb-ddr5-128-bit/

Cu un minus pentru ultimele 2 ca au doar 2 anisori garantie.

Recomandarile de mai sus sunt foarte bune, de preferat este sa cumperi o placa video mai perfromanta cum ar fi acel HD6850 dar asta in cazul in care ai un procesor bun, un quad cu frecvente mai mari. Daca doresti sa investesti o suma mai mare de bani pentru placa video, sa zicem de 1000 RON (HD 5850, GTX 570 etc), atunci ai nevoie de o platforma mai noua cum ar fi Core i5/i7.

In situatia ta merge , insa mai sunt situatii in care o placa de baza cu pci x16 1.0 nu va accepta placa video 2.0 .
Ma refer la placi de baza vechi cu chipset gen nforce4 .

PCIe 1.0 = data rate 250 MB/s , transfer rate 2.5 GT/s
PCIe 2.0 = data rate 500 MB/s
PCIe 2.1 = acelasi data rate cu 2.0

O placa video 2.1 merge pe 2.0 fara nici un fel de problema , deasemeni merge si pe 1.1 , insa nu va merge pe 1.0 deoarece biosul placilor de baza cu acel slot / tehnologie nu suporta placa video ( nu o recunoaste , implicit nu booteaza cu ea ) . Cu un bios modificat va merge , insa la viteze foarte scazute .
Fizic , slotul PCIe este acelasi 1.0 1.1 2.0 2.1 .
Sper sa te ajute .
In principiu o placa video de ultima generatie va merge pe ori placa de baza scoasa pe piata dupa 2008 . Chiar daca iti scade tie viteza aia de transfer in aplicatii video nu o sa vezi mare diferenta . Poate 2-3 fps`uri mai putin in jocurile unde ai 50 constant si 10-20 fps`uri in jocurile unde ai 100+ .
Dar repet in cazul tau , e compatibila si merge la viteze maxime fara nici o problema .


Si un exemplu real cu care m-am confruntat zilele trecute .
Mi-a cerut un "client" sa ii fac un upgrade la o placa video , deoarece 7200GS`ul lui nu prea mai face fata .
Placa de baza era o GIGABYTE K8NE cu un athlon 64 3000+ . Placa de baza vine cu PCIe 1.0 . 7200GS merge frara nici o problema .
Insa placa de baza nu booteaza cu un 8500GT ( 2.0 ) .
