Hey all,
So I picked up Metro 2033 thinking that my rig would laugh at it same as it does with Crysis. Was I wrong, as were many ATI users.
Anyhow, I did some VERY marginal overclocking on my 5970. Granted, twice I upped the voltage to 1.1625v (which ATI Overvolt utility does automatically, no other options) and upped the core frequency to 800mhz and the memory to 1200mhz which would almost bring me to the stock 5870 clocks. The whole computer froze. Had to do a hard reboot. This was after I did the below.
The first time however, I took the OC slow. Running furmark 640x480 and adjusting in 25mhz increments with MSI Afterburner. As was recommended by the guru3D and of course the ATI Overvolt I adjusted the Core voltage to 1.1625V and got the Core/memory clocks to around 800/1200. Ran it for a few minutes in Furmark and the temps were staying pretty solid.
Started up Metro 2033, and noticed a pretty nice FPS increase! The game froze about 1 minute in and had to do a hard reboot. The GPU temps only reached ~55-60c so it wasn't a temp issue. Immediately, I thought it must be a PSU issue as it really was a small Overclock for the 5970. Which was made to be overclocked and has a "massive overclocking headroom."
After this, I ran into some strange and scary graphical issues which leaned me towards expletives that I had somehow fried my GPU *knock on wood*. Like it said, very small overclock and voltage increase that I did and the temps were PERFECT.
After booting up, my internet wasn't working. Odd. It said there was no network. I rebooted and all was fine. I preceded to load up Mass Effect 2 with my usual settings 8x AA edge-detect and 16x AF high quality. Eats the game for breakfast. No OC'ing applied.
After clicking the ME2 shortcut, Steam loaded up, and then BAM. A bunch of vertical lines and random anomalies showed up on the monitor with random colors. Odd thing is that the 5970 wasn't doing much if any work yet as it was still on the desktop. The lines went away as I moved my mouse cursor over them, most of them at least. Rebooted and haven't seen that again since played a few games without issue.
But damn I was worried after seeing that, certainly thought something had gotten fried. Could the freezing upon upping clocks/voltage (increasing the voltage quite a bit from the 300W 5970 stock) be the PSU being overloaded?
I don't understand why I had a (stable?) overclock in Furmark, which is burning my GPU to hell. And then loading up Metro 2033 with my GPU temps in practically the idle temp range and having the computer freeze on me. If it was a PSU issue wouldn't the PSU freeze as soon as it was overloaded?
I don't know, I'm not very informed on PSU's, this was the first computer that I built but I have taken care not to do anything too crazy. I have added a lot of stuff since getting the computer, maybe it is too much for the PSU. I ran my computer through the power supply calculator and it only came out to 623w with the OC cpu and both graphics cards. Here is all I have.
i7-920 @ 4.1 ghz
HD 5970
9500GT 1GB for PPU
Asus p6t Deluxe v2 mobo
6GB OCZ DDR3 (3 sticks)
Auzentech Prelude X-fi 7.1
Coolermaster Hyper 212
Antec 1200 case
DVD/CD RW drive
3 Samsung Spinpoint F3 1TB HDD's
And my PSU: 850W Corsair TX.
Is this my graphics card or PSU?
I noticed the above issues as explained after a couple reboots with no OC'ing which got me worried, especially the artifacts on the desktop. None of the OC I did should have done any damage to the 5970. Do I need a larger PSU?
Thank you.
