Looking to cool down a HD4870

Get memtest and run it. Rounding errors in Prime95 that quick indicate a massive problem with your ram. You can use this program to quickly get it on a small usb key.

Ran it for a while, no errors. Remember leaving it for a few hours before, getting no errors for that also.

In the "MB Intelligent Tweaker(M.I.T.)" section on page 54 I set the "Performance Enhance" to "Basic", to see if it does any good :S

Probably asking for too much, but is there any tool to test all the system?

Gonna try http://www.ozone3d.net/benchmarks/fur/ on the advice of one of the lads here.

If prime is failing that quickly and your ram is perfect then I'm afraid your chipset or cpu is on its way out. Its rare but not impossible. If you could get a hold of another mainboard or cpu and run a stress test it would stand you in good stead.

the_syco

Ran it for over 14 hours, and it's all good, so I hope that clears ithe RAM.

Aye. Will look for a LGA775 loan off someone.

If it says "no code to be inserted here", please refresh the page. It's a known vBulletin bug.

the_syco

Running OCCT to stress test the CPU. So far, at 30 minutes, no faults.

The annoying thing is, it's hard to replicate the fault. I may only get the black screen thing once in a night, but sometimes several times. This makes troubleshooting the problem harder. Thought it only happened when the GPU hit 100%, but the GPU hit 100% in the last GFX test, and it didn't black out

/edit
OCCT test complete, no errors.

RAM, CPU, GFX card looking okay. No to find a stress test for the motherboard, and see what results I get with it?

Cuddlesworth

Interesting. So now your cpu is passing a stress test, your graphics card is passing a stress test and your ram is fine. If there was a issue with the mainboard it would have manifested itself in one of the other tests.

Can you clearly and accurately describe what actually happens when the machine crashes, frequency and length of time playing when it crashes and time of day too?

the_syco

Running OCCT (CPU), MurMark (GFX), and Prime95.

Prime 95 threw up error:

[Apr 5 21:15] FATAL ERROR: Rounding was 0.5, expected less than 0.4

After about a minute after I started it.

Well, I only play CoD in the evenings (work during the day), so usually the crashes happen between 9 and 12 when I'm gaming. I'd be playing BLOPS, and the picture would freeze for 8 seconds, and then the screen would go black for 17 seconds. If I alt-tab, the message saying my display driver stopped working. During the "black screen" period, my the LED on the power button of my (Dell) screen would go from green to amber, then back to green, and the picture would come on. In BLOPS, I can usually continue playing. Heck, sometimes I'm still alive The game accepts commands when the picture freezes - when the screen freezes, I press "Z", or "go prone", and when the picture comes back, I'm in the prone position. Have taken a screenshot when the picture froze, but I only get a black screen.

This crap used to happen in BF:BC2. Here's a picture of the "display driver stopped responding" message that I'd get in BF:BC2: http://www.boards.ie/vbulletin/showpost.php?p=69545779&postcount=99

Vaguely remember getting kicked due to Punkbuster error in Battlefield, see here: http://www.boards.ie/vbulletin/showthread.php?t=2055872351

I think all these issues are interconnect, f**k knows how, though.

Syco I used to get that error aswell.From memory its an atikmdag error.

Theres a few fixes around and one of them was disabling ati error reporting I think.

Or something to do with extending the time delay of the error reporting.

I tried **** loads of so called fixes and one of them worked but I cant tell you which one.

hi the_syco,
Just letting you know I was having similar problems with my 4850 crashing.
I was getting 95+ degrees c so I took the heatsink off to have a look.

What I found is that I had to also take off the plastic cover on the
heatsink as well. I found a good bit of fluff blocking the holes there.
The thing is, you can't see the blockage until you take off the plastic cover!

I then reapplied thermal compound and since then my gaming temps have dropped to about 80 degrees (without manual control on).

Hope that helps.

Right, from the part that says

TdrDelay: REG_DWORD. The number of seconds that the GPU is allowed to delay the preempt request from the scheduler. This is effectively the timeout threshold. The default value is 2.

I made HKLM\System\CurrentControlSet\Control\GraphicsDrivers\TdrDelay
with a value of "666" to see if it delays the crash...

Also, from the part that says

Ensure that the DirectX graphics application does not run at a low frames per second (FPS) rate. As the FPS decreases, the likelihood of the GPU getting reset increases. If the application is running at 10 FPS or lower and a complex graphics operation is about to start, then a flush can be inserted.

I noticed it mini crashed at a FPS of 51, so I turned the GFX option in-game from "EXTREME" to "HIGH", and turned off "V-SYNC". Still crashed with an FPS of 193, but it was for a way shorter time.

Will try other games on lesser GFX, and see what happens. Will be gaming at Midlans alot this weekend, so will troubleshoot it there. Have saved the page above so I can read it off-line.

After a short period of stableness, it started acting up again. This time, freezing the entire machine. Whereas before, the Minecraft window may freeze, screen blink black and the game would no longer respond, the entire screen now freezes, and doesn't unfreeze (have left it for 30 minutes).

Also, I got a BSoD of "IRQL GT ZERO AT SYSTEM SERVICE". Googled it, and I saw audio conflicts mentioned. Pretty sure I had disabled the onboard sound (but it could've been the last mobo), but I went and disabled it (Azalia Codec) in BIOS regardless. Will see how it acts now.

the_syco

Another freeze. Couldn't ping it from another machine, nor could I remote into it. Got a gig of RAM of Hellrazer, so will see how that goes over the weekend.

Overheal

freezing eh. Its been a while since I bothered but when I ran TF2 on the 4850 downstairs, it skipped quite a bit, to the point of frustrating. Every 3-10 seconds or so there would be a little blip where the fps shot to 0 or 1 and went back. lerp (whatever the hell that metric is) would go nuts on the source engine performance chart.

the_syco

Well, freeze/crash. Doesn't respond again. Have left it for 30 minutes once, but it stayed frozen. The screen freezes, and totally locks up the system

the_syco

So... after the latest freeze/crash during BLOPS, I took out one stick of RAM.

BLOPS on 2GB of RAM is not great, I find :pac:

The first stick of RAM, lots of lag, stayed laggy, then got a freeze/crash.

Switched with the second stick of RAM. A bit laggy at the start of the level, and after I respawn, but okay apart from that. Played a few matches, with relatively little lag.

A faulty CM2X2048-8500C5D DIMM it would seem. Will play a bit over the weekend to see how it goes, and may just need to replace the DDR2 8500. Don't know if I can replace just one DIMM, or if I have to replace the set?

That wasnt a bad guess so with the faulty ram--Did you pop in the 1gb stick I gave you?I know its slighty slower ram but it should be ok for testing.

Not yet, no. I decided to see which one caused the lag by itself, and go from there, as opposed to putting the DIMM I got from yourself. Once I confirm beyond a doubt that it's the one faulty DIMM, I'll put in the stick you gave me.

the_syco

Got onto Corsair about it, told them the entire story, and the testing and troubleshooting that I did, and they issued me with the RMA code. As it's a duel set, they've advised me to send both back (to ensure that the ones I get back match better), so I'll play Duke over the weekend, and then send them back next week.

Good times, this turned into a bit of an epic thread. Hopefully the RMA is the end of it.

the_syco

The latest update:

Thank you for choosing Corsair.

We have received your RMA ******* which unfortunately is for an obsolete/discontinued product which is no longer available for direct replacement. Under our warranty policy we are able to offer you alternate replacement. Please confirm to us at your earliest convenience.

Don't think I've any choice in the matter Or do I? Or would there be that much of a difference?

Hehe thanks for the long thread Syco. I'm having some issues with certain games myself. Most run fine but a few cause the system to lock-up. Like yourself I'm running a HD4870 and some Corsair memory, so I guess checking the memory will be my first port of call.

the_syco

Seems either I accept the substandard memory, or they could give me some DDR3 memory...

So, next question: which is better; i3, i5, or i7?

It'll be used mainly for gaming, but I also use it for lots of photoshoppage, and a bit of video editing. Thinking if I get a mobo, some "i" chip, and tell Corsair which RAM to give me, I can get back to gaming. On the plus side, DDR3 RAM is quite cheap atm.

The i5 2500K.

Its the logical choice for gaming. The i7 2600k is just throwing money away, and the i5 beats the i7 in alot of games for pure frames per second.

Didn't work 21 days later they only sent me 4GB's of RAM back. Meh.
