i5 4850 crash in games

Rich43 · 5 Nov 2009 at 01:19

When I am playing a game that stresses my system such as GTA IV, it freezes for a few seconds and then both of my screens (I have dual monitor) fill up with a solid colour. Monitor 1 and 2 usually have different colours for some reason when crashing.

I have tried intel cpu stress test and "FurMark" to stress the gpu - http://www.ozone3d.net/benchmarks/fur/

Both tests have no problems after running for an hour or so.

CPU/GPU temps in the 50-60C range.

Not running overclocked. BIOS factory settings. BIOS upgraded to latest version.

Running Windows 7 x64. Latest drivers all round.

Heres my PC specs: http://valid.canardpc.com/show_oc.php?id=809168

Spent £500 on upgrading month or two ago and it is very frustrating, I have been trying to fix it for ages. I have suspected the Raptor hard drive could cause problems as a similar drive did on my dads (he has a old 775 mobo though), but can that really cause such a odd crash? Is it really likly to be my hard drive? It came new out box when I put it in.

have you tried memtest?

Try relaxing those memory timings, try 2t-8-8-8-24-trfc88 set the voltage at 1.65v for the memory
(rest of settings leave as auto, make sure to adjust both sticks), see if that helps, i have ocz memory and have had trouble getting them stable, cant get them to run at 7-7-7-20, worth going over to ocz and report it there as theres quite a few people with memory probs on the ocz site

Also what power supply do you have?

my cpuz

What the heck...

I just had a go at getting a CPU-Z validation thingy after looking at yours and this is what it printed out: Clicky

What the devil happened to my memory timings... the XMP profile set it to 7-7-7-24 and I didn't touch it after that o.0

Ok, I will try that when I get home from uni.

I have a corsair tx 650w.. I decided not to skimp on the power supply in hopes of better stability.

hyperst's pc is almost a spitting image of mine! So this looks promising advice.

memtest actually didnt report any faults last time i checked. I have been building pcs for years so I thought of that. Memory modules would frequently go bad with my old c2d ddr2 rig (though thats probs due to me overclocking). I will relax the timings when I get home and report back though.

Edit: Also tempted to somehow swap them for another brand now ive read above posts

Ok guys, Im still having problems even after upping memory voltage, cas latencys etc. If it is my memory, what part should I replace it with? It is still memtesting with no problems. Sometimes crashes in windows gui and sometimes while gaming.

I just want to get any bad parts out my system now as I am fed up with it.

Is the 4850 clocked?

The 4850 tends to have problems running games with a dual monitor setup when the card is clocked.

I have both and have experienced similar problems with games running a clocked 4850 with a dual monitor setup. (i now either disable the monitor if i want to run a clocked card profile or disable a monitor via the desktop - if i want to game.)

If you are/have - either de-clock the card and test or try disabling one of the monitors in the destop settings and see if you have any success.

Edit: Even if the card isn't clocked i would still consider disabling one of the monitors and testing...

Good luck.
