@wong: The problem was, when playing skyrim for like... 45 minutes with the side panel ON, the temps would hit about 100C and start running the cooling fan at 100% and really made me nervous lol.

I don't think 500W is enough for two of these cards. Plus you have three hard drives. About the card hitting 100C, there's definitely something wrong with it. Try reapplying TIM and see if it helps.
Need a doctor??

I dismantled the card and wiped the GPU clean and reapplied some new thermal compound. The card at idle seemed to be at about 59C and thus several degrees cooler. I definitely agree that the 500w PSU might be cutting it close. I also have a push/pull CPU fan that's 3-pin, it goes and hooks both in to one and in to the board... It's only a 1,800 RPM on each fan... But yeah, we'll know if it boots or not when I plug them in lol.

I'm probably going to be pulling one of my hard drives out. I just need to swap some data files.700

I loved my PNY 9800GTX it was one of my favorite cards since it overclocked well and ran cool. In bad company 2 with everything maxed at 1920x1200 I would average about 42fps and that was with a i3 540 @ 4.4ghz. Newer games like bf3 choked the vram and caused bad performance and only allowed settings to be on medium at 1920x1200 and 30fps. I know my card was only 512mb but would still score 14000 vanatge points and with overclocking from 738mhz to 850mhz I achieved a score of 15789. Overall I really was pleased with the card for over two years but bf3 took it to its knees and had to upgrade it. I would have gone with a sli setup myself but I would have had to get a new psu and with my money I decided to get a whole new setup. Cheers if you go sli!

Or if your OVP doesn't work properly you could fry some components once it hits full load. Is it a quality power supply?

Looks like you have really poor airflow in your case which could result in really high load temps. If you have tools or access to a dremel I would cut a hole at the bottom of your case and put a good 120 or 140mm fan to blow air up into the bottom gpu at least and maybe a side panel 120mm fan for the top gpu.


A problem that I encountered with my sli setup was hot air from the bottom gpu being pulled in by the top gpu causing it to run 10c hotter under load. I have since added a 120mm fan at the bottom of my case to blow and mix cool air to stop the excess heat from being pulled into the top gpu. I now run both cards within a 4c difference of eachother under full load while gaming and was able to get a stable overclock of 950mhz on both my 560ti's never going above 75c. thumb.gif
450

Bottom line is you need more airflow in your case and a stronger psu. good luck biggrin.gif

It's Rosewill brand that came with the case, like a T something series case from 2010. The motherboard I have is an M4A89TD Pro USB 3 board and seems to have great reviews for OVP and other failsafes designed for optimal OC'ing and performance..

As for the case, it has a side air duct it came with with a tube and round port that was normally sitting over the CPU, but since I upgraded to the push pull system I can't fit it there.. I MAY be able to attach what I think to be a 40mm fan there to draw air out. As for cutting.. I'm contemplating just taking everything out of this case and moving to an Area 51 case that I have that is a little bit larger, and has a completely vertical setup for the hard drives so I don't have this mess of wires in the way in one area...

the little vent area next to the PCI bays, it's tall, multiple holes, is there any special fans that go here? Ones that go up and down? I think ya'll may know what I'm talking about, if not I'll take a picture.

Sandy, That isn't a BTX case is it?

It is a Phantom and I love it! I have gone from a Antec 300 (first version) to a NZXT H2 and now to a NZXT Phantom. I wanted the best possible airflow for my SLI setup and after hours of reading reviews and going to Fry's I decided that it had the best features and airflow for the price. The day I got the case I spent like 5 hours doing cable manegment and figuring out the best way to mount everything. I can say that with three 200mm fans and 6 120mm fans including my h60 push/pull I have achieved the best possible airflow.

Look at pci slot coolers like this:

Okay I have a bit of a .. puzzling... situation..

so without the SLI bridge adapter on the slot closest the the rear of the case, the device manager reads TWO 9800 GTX+ / 9800 GTX 's installed...

After putting on the SLI adapter, it reads a GeForce 8800GT and 9800 GTX + / 9800 GTX

MSI Afterburner reads the card as the 9800, however my clocks are as follows:

Core: 700
Shader: 1728
Memory: 1100

The GTX+ I just bought and was using by itself awaiting my SLI bridge to come in the mail was reading higher than this for clock speeds...

Did I do something wrong? Am I going to need another SLI bridge after all? Do I need to move the one I have?

Also, I just tried running Mass Effect 3 while running Afterburner on the other monitor to monitor GPU usage and GPU 2 is getting all the usage and GPU one is getting nothing... Is it possible I installed the SLI bridge upside down? Or is this not possible?

Thanks so much everyone for their time.


EDIT: I was perusing the web in an attempts to solve this myself, and signs point to putting the faster card, the GTX+ in the 2nd slot, and the GTX in the first slot.. On top of this, I am reading that you must enable SLI in the Nvidia Control panel, however I do not see this option anywhere... I'm really perturbed by the fact that with the SLI bridge on it is reading my GTX+ as a GeForce 8800 GT

Edit: I'm SUPER RAGING, I installed the SLI Bridge and rehooked all the power/sata cables and my boot sector vanished... I was super peeved to get the "Insert Proper Media or Boot Device" message... Fortunately windows.old had all my stuff I hadn't finished rearranging on other drives yet.

@Sandy: With all those fans, how's the noise levels?

I'm thinking it might be a voltage issue at this point to be honest with you.

What psu do you currently have in your rig?

Honestly when set to low it is whisper quite and the pump on my H60 makes more noise than the fans. I have 495cfm of intake and 245cfm of exhaust so i have a very high pressure case right now which is awesome for dust levels staying down. thumb.gif
