Going Tri-Sli: A Few Questions

post #1 of 6
Thread Starter 
Hey everyone,

Finally decided to go Tri-SLI now that I've been able to locate a few parts and I had a question or two to pose everyone.

The first is in reference to IOH voltages. I've currently got mine set to 1.2, but I remember briefly reading a post or article on how going Tri-SLI can require an increase of an additional voltage bump of 0.1v. Can someone elaborate on if this is true and if so why it might be necessary?

In addition to this if there are any other possible areas of concern that someone who's familiar with the possible problems or has it done it themselves can offer?

Thanks in advance,

Lampen

I haven't heard about the voltage issue before, but that just me.
a few thing to what out for: game support can occasionally be iffy, and scaling issues have been known to occur.

When I was running Tri-SLI, I didn't have to bump any voltages or anything. Took it out because it sounded like a jet taking off everytime I game. lol

Not to mention the amount of heat these 3 cards were creating (not much airflow in a 800D).

If that game is FSX, then it is a bonus sound effect

First of all great looking setup. Very clean and orderly .

Yeah heat has been the one thing I immediately thought of when deciding on getting a third card. I bought the HAF-X in expectation of that though and have filled it with a lot of high CFM fans to get nice cold air in and waste heat out as quickly as possible.

Oh and you've conveniently got the exact same power supply as I do. I assume you did the following:

CPU and GPU 1 on the first 500w unit
GPU 2 and 3 on the second 500w unit

Thanks for your input!

lol Too bad I don't have that game.

Heh, thanks! I just threw everything in together.. didn't really organize it that much.

As for the PSU, I just hooked them into the PCIe 6 pin slots (since they're modular). Didn't really pay attention to which cable goes where.
