Hi everyone,

I have two GTX 770's in SLI together

The PSU is FSP 850W Aurum PRO Series Modular PSU, 80PLUS Gold

The motherboard is Asus z87 Expert Motherboard.

First time asking this question had led to a believed overheat issue, I have since installed another 3 noctua case fans (Total up to 5) and the Graphics cards run at 20-30 degrees idle and 55-65 degrees when running a game.

They are also pushing to a triple screen 5874x1080 resolution.

However, after about 5 minutes, games slow down before freezing with the screen going dark but the game continues to run in the background. A hard reset is then required to bring the computer back up.

The previous drivers have been removed with driver sweep, latest drivers have been clean installed from a fresh start and the rig has also been run on previous versions of the drivers all to no avail.

The graphics cards also run fine on their own. (In fact they seem to outperform their SLI counterpart. Go figure)

Does anyone have any ideas/ solutions to this issue?

Regards

Does this apply to all games? Maybe it's BIOS problem you might wanna check that.

It wouldn't cause this problem as display ram and ram dynamically allocate ram i.e ( if i had a gpu with 2gb of gddr5 it would dedicate 1.5gbs of ram to a demanding task like bf4, but if i had a 1gb gpu it would only dedicate 0.5gbs to prevent 100% dedication. But maybe your Bios could be broken and might over dedicate ram. Then and again chances are it will blue screen if that happened but worth a try to see.

I'll run through a bios check tomorrow after work and see if that solves the problem.

The CMOS Battery is needing replacing but I wouldn't expect that to interfere with games in this manner, but I'll get it replaced and see.

Also I think 4gb of VRAM is fine for my setup as it has been running under a single GTX 770 with steady 60+ fps in most games for months. To answer the question though, I have 8gb of PC ram in my system at the moment also.

Unclemao you win the genius prize of the day and I win the moron prize. $100 worth of case fans later and the fix was a $3 CMOS battery.

I never would have thought that a dead motherboard battery could have such an adverse effect on my hardware like that. It's a real eye opener and it serves me right for not fixing it when I first discovered it.

Thanks all for your input
