Default Intel P45 stie SLI?

SLI Hacked on Older Intel Chipsets
NVIDIA's SLI multi-GPU technology served as the biggest selling point of nForce series chipsets, as it was exclusive to it. With the advent of LGA-1366 processors and the Intel X58 chipset, NVIDIA allowed the Intel chipset to support the technology, as it soon became clear that it isn't going to be easy for NVIDIA to come up with an LGA-1366 chipset. Users of the older LGA-775 however still have the option of buying nForce 700 series based motherboards to use SLI, and hence no real attempt was made to ensure the technology is available to Intel chipsets. Until now.

A member of Expreview's Chinese enthusiast community has successfully enabled SLI on an Intel chipset based LGA-775 motherboard, the first feat of its kind since much older attempts on i975 platforms using much older GeForce hardware. Firewings_[CCG] successfully ran SLI of GeForce 8600 GT and GeForce GTX 260 cards on his Intel X38+ICH9R chipset based ASUS Maximus Formula motherboard. The feat is headed by software he modified, details of which will surface soon. The mod was validated by Expreview staff, who used the software to run GeForce GTX 260 SLI on a more recent P45+ICH10R based Maximus II Formula motherboard. "By installing the software that Firewings [CCG] provides us, we managed to enable SLI configuration in Directory Services Restore Mode. Due to some 'small problems' according to Firewings [CCG], the SLI configuration can't be realized in normal mode for now, but he says this will be fixed soon," commented Expreview. With SLI enabled, the multi-GPU setup was able offer performance scaling that proves the mod works.

Pentru cei mai tineri, trebuie sa va spun ca existau driveri care activau SLI pe i975X. Probabil ca se poate face si pe celelalte chipset-uri Intel, cu putina bibileala. Problema cu chinezii de mai sus este ca nu au spus cum au facut, si mie asta imi ridica un semn de indoiala. Spun asta deoarece se poate face SLI si altfel, pe orice platforma, cu o placa de extensie pe care sunt montate doua sloturi PCI-E si un chip nf200. Ma rog, in cazul asta chiar cred ca au facut SLI, dar metoda ar trebui facuta publica, pentru a fi utila tuturor.

Sal,
Daca nu ma insel la Gigabyte modelu cu i975X stie si SLI si Crossfire,acum ce au facut cei de sus pe P45 e o chestie tare......dar cu ai spus si tu, trebuia facuta public metoda.

e vorba de drivers, scosi de nvidia.
a fost o perioada (destul de scurta) cand SLI a fost suportat si pe cipsetul intel x975.
e o versiune destul de veche care nu include nici macar seria 8 de la nvidia, deci cam inutil pentru entuziastul "modern".
Placa de extensie cu cipul nf200 este destul de scumpa si aproape imposibil de gasit in romania, solutia de "crack" care e ceva nou pt utilizatori este una ideala, va oferi posibilitati de OC substantiale (pe proc) oferite de platformele intel si in acelasi timp puterea SLI.
Sunt nerabdator si optimis ca aceasta solutie va deveni cat mai publica si ma voi putea juca ia cu piticii mei de pe creier care ma ciocanesc zilnic cu "SLI"

"Sunt nerabdator si optimis ca aceasta solutie va deveni cat mai publica": pai...daca X58 si P55 suporta SLI, cat de (mai) publica trebuie sa devina treaba?

Aici este vorba de cei care nu au o platforma bazata pe X58 sau P55 dar ar dori totusi o configuratie de tip SLI, pe o placa de baza cu un chipset Intel mai vechi.

asta am inteles, dar tocmai vroiam sa dau de inteles ca din ce in ce mai putini au asa ceva. Trebuie sa privim in viitor, nu in trecut...in trecut sunt destule placi cu SLI, anyway (inclusiv al meu super-vechi K8N Diamond ) ) (si pe care ar trebui sa fiu retard sa fac SLI - ideea este ca SLI faci cand ai si un proc care sa sustina configuratia video)

poate sunt nostalgic, poate sunt nebun, dar eu vreau sa scot ce se poate mai mult din procesorul meu (Q9650), OC calumea nu pot decat pe cipseturi intel, daca verau sa-l fac "monstru" trebuie sa am SLI, asa zic piticii mei, ce sa fac daca-s fanboy nvidia?

Si eu am facut SLI acum ceva timp pe P35, 965PE si pe 975X cu 2 x 7900GS. Din pacate driverele nu au mai fost updatate (probabil si-a bagat NVIDIA coada) si nu suporta nimic peste seria 7.

Drivere updatate pentru P35/P45/X38/X48 ar fi un lucru excelent pentru ca mai sunt multe placi de baza bune cu procesoare puternice capabile de a tine un SLI (E8X00, Q9XX0, etc) !

De acord ca trebuie sa privim spre viitor.

Insa:
- Cred ca te inseli in privinta posesorilor de P45 sau mai vechi. Daca te uiti pe alte forumuri prin semnaturi, o sa vezi ca inca sunt multi utilizatori de P35.
- Dupa cum bine stii, P35 suporta CrossFire (x16/x4), la fel si P45 (x8/x8). Deci de ce nu ne-am chinui sa facem si SLI?
- Pai daca ai un quad pe P45, atunci nu e asta un proc bun?
- Probabil ca stii ca placile Nforce sunt destul de problematice, motiv pentru care o mare parte din utilizatori s-au ferit de ele.

Pe configuratia mea, nu am testat inca CrossFire. Am testat insa pe EP45-DS3 de la Gigabyte, cu 2 x 3850 si 2 x 4850 si se simte diferenta chiar si in 1024x768. Intr-adevar, in perioada cand aveam GTX260, acesta era limitat de procesor. Dar GTX260 e o placa foarte puternica, si daca chiar vrei sa joci la rezolutii mai mari de 1680x1050 atunci inseamna ca ai bani de configuratii mai puternice

Configuratiile multi-gpu pe segmentul mainstream sunt rentabile de la HD4870 sau GTS250 in jos

SLI se poate realiza si numai software la ora actuala, chiar varianta soft este un pic mai rapida decat cea cu NF200. Cu un bios pentru placa de baza si un driver video corespunzator nu ar fi nici o problema, totul este sa existe interesul producatorului, aici este marea problema deoarece pentru el inseamna zero vanzari .

Da, am citit articolul ala acum vreo 2 saptamani parca.E relativ simpla chestia daca ai la indemana codename-ul din driver al placilor de baza de la diversi producatori de X58 care au primit licenta de SLI
Ma refer la asta:
"987134512781Genuine NVIDIA Certified SLI Ready Motherboard for ASUS RAMPAGE II EXT 3287-Copyright 2008 NVIDIA Corporation All Rights Reserved-765289891023(R)"

Da, intradevar SLI este o solutie buna dar scumpa, pentru ca intotdeauna apar placi mai noi cu performante mult mai bune...
