  1. Hi guys, so i do some Benchmark test and i have to much problem with the Ati CCC Overdrive (much test shutdown before the end), so i return at my initial Vbios or Svl7 bios and i uninstall and reinstall the last driver Ati for to remove the Overdrive acces on ATI CCC (15.7.1) Now the benchmark test passed ! I changed my 1 mm thermic pad by 0.5 mm and i win 3 at 4 degrees ! Nice! Thank you Nospheratu for this Infos !
  2. Hello, I would like to tell you something strange In normal, with the M17X-R2 is not possible to use Overdrive Ati CCC with the 7970m Dell and the Original Vbios 015.017 but with the Vbios 015.022 Overdrive, yes! However, i put the Vbios 015.22 Overdrive, i put the last driver Ati CCC 15.7.1 and it was good but after some minutes, at 76°C in the play "World of warplanes" in max resolution, some big artifact appeared in the screen so i come back at my original bios 015.017 modified at 0.975v by VbiosPacher. All now is ok! (no artifact) I come back in Ati CCC (with my my original vbios modé) and i see the Overdrive and it was opérational so i put it, but after some minutes in play, i have some small artifact. So i take my orginal Vbios (015.017.000.001) and i do an other Vbios by VbiosPatcher with 0.975v, 875 Mhz and 1250 Mhz (original is 800 Mhz and 1200Mhz) and when i play the max, i see in HWiNFO64 is 800 and 1200 and not 875 and 1250. before with the 15.3 driver ATI i see what i put in the Vbios but know with the 15.7.1 driver ati ,no! But if i synchronise my Vbios modified with the Ati CCC Overdrive like for exemple: my Vbios: 0.975, 875 Mhz and 1250 Mhz and the overdrive at 875 Mhz and 1250Mhz, it's ok and i have not artifact. So, in conclusion: we can use Ati CCC Overdrive with all Svl7 Vbios, i mean "AMD 7970m (Dell) VBIOS package" if we put in first the Vbios "Dell7970m - 015.022.000.001.000000.C42904A1.119 - OverdriveMod - UV 0975v" and, install the last driver Ati ccc 15.7.1 and come back with one Svl7 Vbios. and after for not artifact, synchronise (put the same frequence) in Ati CCC Overdrive with the frequence of the Vbios svl7. And it's OK ! What do you think about this ? My computer shudown at 87.5°C but in générale i have: in 2D, 31-34°C at 1675 rpm and in 3D it's between 76°C at 85°C at 4156 rpm. Maybe i bought the thermic past Gelid GC-Extrem for remplaced Noctua NT-H1 but if it's just for to win 1 or 2 degrees , is not the best idea ! I have to find a very good tray with fan, Do you know sone one ? (Sorry for my bad english!)
  3. Hello ! (sorry for my bad english! (but i'm french)) Thank you for all the work that has been done on this forum, thank you to you all. I just buy in EBay one graphic card HD 7970m for my old M17X-R2 for to replace my 5870m CrossFire. My m17x have a bios A10 modé V1F. (The last bios modé for this machine, i mean) My 7970m is Dell model with Vbios 015.017.000.001.042717 (133-C42904A1-117). I bought NT-H1 Thermic past and Phobya thermic pad (7W/mk) in 0.5 mm and 1 mm because i have a problem with my 7970m. My 7970m turn correctly at 36-37°C but when i do something in 3D, she goes 87°C and my computer crash. So, in theory with my new past and pad this problem should be set but i think is not normal the 7970m shutdown at 87°C . Why is not 95°C or 100 C° for shutdown ? is it possible to change this by the VbioS, the bios or windows ? Before, with my old 5870m CrossFire I changed my VBIOS and I do my personal VBIOS with RBE and AtiwinFlash for to have the Overdrive. I would do the same thing with my 7970M, i mean to have the Overdrive but RBE and Atiwinflash does not function properly with the 7970M. So maybe i can put the Vbios: "Dell 7970m - 015.022.000.001.000000.C42904A1.119 - OverdriveMod - UV 0975v" or "Dell 7970m - 015.022.000.001.000000.C42904A1.119 - Overdrive Mod_1050v forced" but with these Vbios i lost my HDMI external, it isn't ? and i don't want. So my probleme is: i want a Vbios for my 7970M with the Overdrive and my HDMI external connectique. Is-it possible ?
