ifrit05 Posted June 3, 2011 Share Posted June 3, 2011 I backed up my ROM a while ago and decided to overclock it using NiBiToR on a XP VM. I loaded it using Chameleon, but is there a tool to confirm it's running at the speeds I specified on OSX? I've searched with no results. Thanks for any help.

ifrit05 Posted June 3, 2011 Author Share Posted June 3, 2011 How could I have missed that? Thanks 3.14. EDIT: It's not using the clock rates I specified. (Core: 612 MHz [should be 800], Shader: 1512 MHz [should be 1800], Mem: 399 MHz [should be 450]). Yes, these clock rates are STABLE, I used to have it overclocked in Windows for a while. Any insight to this? Thanks. Link to comment https://www.insanelymac.com/forum/topic/258436-tool-to-show-gpu-coreshadermemclock/#findComment-1692508 Share on other sites More sharing options...
3.14r2 Posted June 3, 2011 Share Posted June 3, 2011 I have GF 8800GTX (EXtreme Overclock edition by PointOfView). I have it flashed with 8800 Ultra BIOS. It work perfectly. To be honest it was a result of few trials. There were few different BIOS files tested (from different manufacturers), only one of them was good and gave no trouble both in OS X and Windows. My initial goal was to flash it with Quadro FX BIOS, but unfortunately it failed. So flashing Ultra BIOS was a plan B You can find Nvidia BIOS files there. You might find BIOS with higher settings then the stock one has. Also be sure to double check the new BIOS in Windows, just to be sure that NVclock do read data correctly.

ifrit05 Posted June 3, 2011 Author Share Posted June 3, 2011 Well testing it with Windows is out of the question (I have forsaken Windows a long time ago, I don't have it installed on any hard drive or partition.) Plus since I load it using chameleon, testing it in Windows wouldn't work. You flashed it using a similar model, the 8400 GS I have is the newer 64nm chip (G98). What ROM possibly could I load into memory with Chameleon on this card? Or should I just use a unmodified one and OC it myself? (as I have been doing). Thanks.

3.14r2 Posted June 3, 2011 Share Posted June 3, 2011 Well, then you probably can test it out with Ubuntu (any Linux) Live CD. My point is to use some other manufacturer provided BIOS, which might have higher settings then the settings set in the stock BIOS. In other words, you might find a factory made (those properly tested and stable) BIOS with higher values set (instead of changing some parameters manually). I don't know which cards of higher range are based on the same G98 chip, but you might try one from some other model (in my case 8800 GTX/Ultra are very much identical, so a BIOS file from Ultra version works well).

ifrit05 Posted June 3, 2011 Author Share Posted June 3, 2011 Yeah there really isn't any one that's close to a 8400GS. I'm manually OC'ing the values because I know they work and are stable. I was using them for about 3 years. I have put a image of FreeDOS on a USB Flash drive and I'll let you know how it turns out. EDIT: Well, this is stupid. My BIOS automatically disables the onboard GMA950 when you have a PCI-E card installed. So I can't flash it in my current machine. Bummer. Oh well, it's performance is fine anyways.

So I can't flash it in my current machine. Bummer. Oh well, it's performance is fine anyways.Am I missing something? As far as I know, NVidia card can be flashed from an USB bootable DOS pen drive with nvflash tool. There is an onboard GPU (ATI for that matter) on my MB disabled manually. Nvidia card can be perfectly used while booted in DOS and in the process of flashing.

ifrit05 Posted June 4, 2011 Author Share Posted June 4, 2011 I Did just that. FreeDOS on a USB drive, with nvflash. My BIOS automatically disables the on-board GMA950 when it detects there is a PCI-E card installed. I need to use the on-board so nvflash can overwrite the GF's BIOS. So flashing is a no go as of right now.

So flashing is a no go as of right now. this is incorrect you can flash the working card...you can even do it in OSX with some research the bios is loaded into RAM at boot, not used again until next boot no problem at all to change it while running (this is what 3.14 was trying to tell you) Link to comment https://www.insanelymac.com/forum/topic/258436-tool-to-show-gpu-coreshadermemclock/#findComment-1692878 Share on other sites More sharing options...
ifrit05 Posted June 4, 2011 Author Share Posted June 4, 2011 Oh, OK, I understand. I always used another card just in case. So, what if the flash goes wrong? How would I be able to fix it since both my on board and GeForce wouldn't be usable?

How would I be able to fix it since both my on board and GeForce wouldn't be usable? Good question! I've had the same problem (some flash attempt didn't went as planned). The way out was to use a PCI VGA card (I had an old PC collecting dust; just plain PCI - not PCI-E/X). I had display connected to the above spare card and reflashed PCI-E card with working BIOS. Probably an AGP card could also be used for that purpose.(this is what 3.14 was trying to tell you)Thanks!

ifrit05 Posted June 5, 2011 Author Share Posted June 5, 2011 The way out was to use a PCI VGA card (I had an old PC collecting dust; just plain PCI - not PCI-E/X). I would do that (I have a whole cache of older PCI/AGP graphics cards due to me and my father running a computer business), but my computer uses low profile only. I am no stranger to BIOS flashing. I have some older PowerPC macs that I acquired over a couple of years that required me to flash a couple of older Radeon's over to Mac. Thanks for all your insight. I appreciated it.
