So, recently upgraded my computer a bit, nothing overly fancy.

Was hoping to crossfire my old Nvidia GT240 1gb DDR3 with the newer card I got, a Radeon HD 7770. But before I can even consider that, I need to figure out why this darned Radeon is overheating. It runs around 30-35*C from the desktop. I'm trying to play Metro 2033, which I'm well within specs for, but even just hitting the main menu screen skyrockets the Radeon to 57-60*C. It took me a couple of tries on the game with the computer shutting down perhaps 10-15 minutes into play before I popped up my temp gauges to see what the deal was. Thought it might be because of space constraints with the Nvidia, so I took it out, it dropped the no-load temp a couple of degrees, but no potato on the game temp. So, yeah, I've never had an issue with a video card overheating, and absolutely anything will be of help.

System Setup:
Intel i7 930
Radeon Sapphire 7770 1GB GDDR5
6GB DDR3 @ 1600
1200W PS
Win 7 64bit

run a program called "unigine valley" which also says ur temps, top right of the screen, tell me how high it gets too.

also you can download "hwmonitor" and run any demanding game.

You need two identical Radeon cards to CF or two identical Nvidia cards to SLI, you can't put a Radeon card and an Nvidia card to work together. You have to uninstall all the Nvidia drivers, remove the 240 and then insert the Radeon HD 7770 install the its drivers. If you want to CrossFire you will need to buy another 7770.

how are you even using a gt 240 and a radeon 7770? what drivers are you using?
because,unless you are using some kind of custom made hybrid drivers, you wont really get good peroformence from both cards(and by that i mean, the card you have drivers for will run good, and the other one at about 10%, and will just cause problems)

crossfire= name of the AMD technology used for multi-gpus
SLI: name of nvidia tech for multi- gpus.

so using 2 diffrent gpus from diffrent companies, is not something you can even do well,and you really shouldnt.( sorry to tell you this, but you should have researched more before buying a 7770)

now to your overheating, whats ur temps under load?
and you tried using the 7770 only i see, but you probably didnt remove nvidia drivers,and installed the right amd one, which might be causing your problem.

I actually found a tutorial on crossing the two cards, but I haven't attempted it yet. Might not be overly worth it either way seeing as the 7770 is quite a bit better than the 240 and will likely do me just fine.

I did remove old and do a clean driver install when I was mussing about with them (did it with the 7770, currently over to the 240 to test it alone). I'm not entirely sure how to seriously test temps under load, I only know that playing Metro 2033 had the 7770 up to 60*C easily. How would I go about testing so I can give you guys something more accurate to work with?

Well first of all, you probably shouldn't have an nvidia and amd card running simultaneously on the same system. It could cause more harm than good such as microstuttering, conflicting drivers, etc. Your 7770 will do just fine by itself.

Secondly, if 60C is full load during Metro 2033 that's nothing to be worried about. Depending on your ambient temperatures those would seem normal to me. I would only start worrying if it reaches over 75C. If you want improved cooling you can reapply some thermal paste or clean off the cooling shroud.

I suppose my question then, should by why the heck my computer flips itself off after about ten minutes of some games. I had a nasty bug of some sort and had assumed the shutting down was related to that, so I wiped and reinstalled (needed to anyhow), but the shutting down is still persisting. I can have the Sims 3 running for hours no problem, and haven't had any issues from the desktop/internet, this is only the second game I've tried since the reinstall, and ten minutes in the computer gives up.

I'm savvy, but no expert. What might I be missing? And should I move to a different area of the forum for it?

Hmm, that's strange indeed. Your PSU is 1200W which is overkill actually and is definitely able to take on a 7770. Are you using stock intel cooler? If you could give us the max temperature readings in game by using core temp then play for about 5-8 minutes so your system doesn't shut down again to see what max temps your CPU is reaching.

Also do the same with your GPU with GPU Z, it will let you know the max temperature the card go to during gameplay.

I'm sure you've already done this but just as a precaution double check to make sure you have no conflicting nvidia drivers, your Catalyst drivers are up to date etc.

EDIT: What is the brand of your PSU?

Apologies, I was out of house for a couple of days there. The temps are all staying nice. Watching through the CorsairLink.

Even though I had uninstalled all the Nvidia stuff, I went through my folders and removed the left behind empty folders for safe measure. I haven't had any issues since then, so perhaps there was some Nvidia residue lingering and jacking things up. Had the game up and running several hours.

Hopefully no more issues at all!

Thanks so much for your help everyone!
