IXBT REPORTS, based on overclockers.ru, that it's possible to perform modifications to the Radeon 9500 to turn it into a Radeon 9700 Pro.
There's Russian text and some diagrams about this claim, here.
There's a part translation from iXBT over at VR-Zone.
One reader ponders whether such a conversion, anyway, would do much more than enable the other four pipelines, but the 9500 only has half the memory bandwidth of the 9700 Pro.

Rough translation of the whole text on overclockers.ru . Is converted RADEON 9500 V OF RADEON of 9700 | tshinyuead | 00:19 As is known, on the base of the architecture Of re00 the company ATI let out whole series of the chips:RADEON 9700 About, RADEON 9700, RADEON 9500 About, RADEON 9500.The first two versions, RADEON 9700 about RADEON 9700, are characterized by only clock frequencies:videokarty on the base RADEON 9700 about work at frequencies OF E2SHCH/'20(EY0DDR) MHz, and RADEON 9700 - 2"shch/shchya0(2"0ddr) MHz.RADEON 9500 about differs from them the reduced by busbar/tire memory - it has the 128- bit busbar/tire DDR SDRAM.And finally the weakest version - RADEON 9500.It has 4 piksel'nykh conveyors instead of eight, which have its three of the "elders of brother". Videokarty on the base ATI RADEON 9500 have 128- bit or 256- bit busbar/tire depending on a quantity of video memory.Since these pays are done on PCHB from RADEON 9700, the 'ya-megabaytnye versions, which have exactly half of microcircuits, have exactly "upolovinennuyu" busbar/tire of memory from RADEON 9700, i.e., 128 bits.Then the y28-megabaytnye pays, which have 8 microcircuits of memory, established/installed exactly as on RADEON 9700, have the "valuable" 256- bit busbar/tire of memory. The impression is created in appearance of the chips of new rule from ATI, that they all are identical.I.e., the off 4 conveyors on RADEON 9500 can be in any manner included.Unfortunately, the attempts to include the missing conveyors by program method did not thus far prove their justifiability.However, as showed our studies, to by apparatus make RADEON 9700 of RADEON 9500 is nevertheless possible .For this it suffices attentively to look to the exterior view of chips (to the left - photo RADEON 9700, to the right - RADEON 9500): It is evident on the photo that one of the resistors, arranged/located on the base layer of chip RADEON 9500, is located in other position.We explained under close examination of the chips of entire rule that this resistor was arranged/located precisely so (2-3) only on the chips RADEON 9500, which have 4 working piksel'nykh conveyors.On all remaining chips, which have 8 piksel'nykh conveyors, it stands differently (1-2).Thus, we act - we resolder resistor to another position (1-2).If suddenly you it lose, that nemudreno - painfully already it small  ,it is possible to establish/install another - the resistance of these resistors is equal to 6,8 k :
It is prepared.Final chord - we stitch through into altered y28-megabaytnuyu videokartu on the base RADEON 9500 from To sappyuire...: ... the "broken up" BIOS from Yuerchules RADEON 9700, undertaken from the page of sharpyy .Thus, it is prepared.Let us test? It works!!!Total calculation - overklokery against ATI - 2:0! .
Let us try dispersal/acceleration.On the pay does stand the memory from Infineon with the cycle time 3.6 ns; therefore memory did drive away not quickly?to 300 MHz .nucleus/kernel?it is much better, from 275 to 370 MHz . Thus, in the testing is participated:1 - pay Of sappyuire RADEON of 9500 y28M without the alteration, 2?pay with the alteration, 3 - with the alteration and the dispersal/acceleration, 4 - as cherished target/purpose?RADEON 9700 pro. the test system:Intel Pya 2800 MHz, MB. ASUS PYAS8KH (SiS 648), 512 MB. DDR SDRAM PCH2"00, Shindoshs KHP, DirechtKh 9, Chatalyst 3.0.Tuning the quality of drawing into Tsuakee arena?to the maximum, in UT200E - Tekhture Of detail:yuigyuest, Shorld Of detail:yuigyuest, Chyuarachter Of detail:yuigyuest, Pyuysichs Of detail:normal, Chyuarachter Of syuadoshs:it, Dynamich Of ligyuting:it, Detail Of tekhtures:it, Prozhechtors:it, Dechals:it, Choronas:it, Dechal Of stay:normal, To foliage:it, Trilinear Of filtering:it. Altered and driven away pay on the base RADEON of 9500 udelala RADEON 9700 pro. Of overklokery against ATI?3:0! I think, about the difference in the prices pays on the base RADEON 9500 and RADEON 9700 about and speaking is not worth.However, RADEON of 9500 128 MB. does stand today in Moscow approximately 200 u.e., and RADEON 9700 about?350 to u.e.The features of poberi, I love ATI! |
