Brewers Posted September 11, 2009 Share Posted September 11, 2009 Hi, I had a weird experience regarding SL the last week. At the beginning of the week, my hackintosh didn't want to boot up properly, I would not get any display output, just the graphics card fan (nvidia 8800GTS / G80) running at full speed the whole time. The system seemed to hang at that stage, I didn't get any BIOS beeps or the system booting in the background. Okay I thought, it's a G80 and I'm not the first one who has the problem of being left with a G80 card with bricked video BIOS (I think that's the problem, after googling a bit). I then resorted to a nvidia 7200GS, which worked fine for a week or so. Then, the same happened. No display output, no POST. Can't tell about the fan speed, since it's fanless. So far, both cards also refuse to work in any other PCs. I would have understood about the G80 breaking because of all the heat it produces, etc. But the 7200GS worked for YEARS in another PC without a single problem. This all happened just in time after I installed Snow Leopard, the G80 worked for maybe a week before breaking down. I haven't done anything particular special about this SL install, but I used fassl's automatic DSDT patcher. I'm not sure if a custom DSDT can cause such permanent problems? Nothing else was changed at this particular system, esp. not hardware-wise. See my sig for specs. I'll change to a nvidia 6200TC later, if this also breaks, I'm out of stock on nvidia cards :/ I'll try to re-flash the 'broken' cards' video BIOS with nvflash and see if I can get them to work again...

vlad1966 Posted September 11, 2009 Share Posted September 11, 2009 Brewers, Sorry to hear about your troubles. I hope SL isn't killing vid cards, the fact the your fan was running a fullspeed would make me think that heat should not have killed it. I personally am running a 3-week old XFX Radeon 4890, but my fan spins up at system boot & quiets down shortly afterwards. Running EVOenabler.kext and Netkas's fix for CI/QE SL.

a7med Posted September 11, 2009 Share Posted September 11, 2009 i had the same problem no display output(this range out of mode ) and the fan speed was to fast my graphics card PowerColor PCS Radeon HD 4670 any solution>????????? Link to comment Share on other sites More sharing options...
bonfilio Posted September 11, 2009 Share Posted September 11, 2009 Pop the battery and reset your cmos. Make sure you aren't overlocking your pci-ex bus (should be 100mhz - usually set for auto on a GB board, and even auto on a simple OC'd system isn't good) as that can kill video chipsets pretty soundly. Unlikely it has anything to do w/ SL, but since installing and having QE running, your card will be taxed that much more and the oc'd pci bus would come into play. If it was one card, I'd say something was up w/ the card. But since it's repeatable w/ 2, I'd suspect the motherboard is the culprit. Link to comment Share on other sites More sharing options...
Brewers Posted September 11, 2009 Author Share Posted September 11, 2009 okay, I figured it out I believe. Plugged the 8800GTS in another PC together with an old PCI graphics card to get video output. The Geforce was recognized as a Tesla card... so this already told me that something weird was going on. It seems that the DeviceID somehow got messed up. Anyways, I flashed the original video bios with nvflash, and the card was recognized correctly and was in a working state again. It still doesn't work on the original Asus board where I had the problems So yes, it seems like the mainboard is messed up. It still doesn't boot, even with an PCI graphics card. I think I'll have to get a new one... Link to comment Share on other sites More sharing options...

Wait...you got it to recognize as a Tesla card!? too bad you already flashed it back to normal, if its me I'd try to install driver for Tesla cards and see if it functions XD Some people in the CAD/Design industry actually intentionally try to modify the device ID on GeForce cards so it would get recognized as Quadro, since there isn't much of a difference technically between these two cards its just the Quadro uses a WAY advanced driver.

Well, I could try to flash it with a Tesla bios It was recognized as a Tesla C870 iirc. But I'd rather have video output than doing GPGPU computing Still wondering how this all got so messed up... I never flashed the card before, and the PC was very stable, save for the last weeks. Link to comment Share on other sites More sharing options...
Brewers Posted September 12, 2009 Author Share Posted September 12, 2009 I think I figured it out. It seems like my 24" Yuraku TFT is somehow broken. I tried the PC w/ the 8800GTS with another monitor, works fine... With the Yuraku, it didn't even want to boot. I then tried the Yuraku with my notebook's DVI out. It was recognized as non-PnP monitor by Win7, so I couldn't use its native resolution. Worked fine a few weeks ago... Looks like the TFT also flashed my graphics card I'm now writing an angry e-mail to the manufacturer, I'll have them repair it or send me a new one. Crazy {censored}...
