hey all, i bought new 4870 week ago and i was busy fixing this problem...
i bought brand new pc:
Core 2 Quad Q9300, 1333MHz, s775, 6MB
EP45-DS3R s775 C2Q 1600Mhz, Intel P45, DDR2 1200, 2xPCI-E
DDR2 800mhz 2x2GB OCZ Vista Upgrade Copper Mirrored XTC Heatspreader
HD 4870 512MB GDDR5 DX10.1 HDTV 2xDVI PCI-E
Ezcool Ps-1000 500watt
HD 500GB Samsung

i installed Vista 64-bit.. did Test with 3dmark.. played Crysis.... Player BF2 and few others games... untill i installed GTA San andreas.... while i playing San andreas my Screens returns to alot of cubes or gray, and after few seconds its become Back with no singal msg. i thoght it's can be a problem with the Windows so i installed XP... The same problem. Then i tried alot of drivers... still crashing.... then someone told me that its becose GTA is old game... so i said ok... let it be.... but today i played Half Life 2 and BOOM, the same problem... after few People told me that the have the same problem, it an problem for me.... the funny thing its all of them got the 4870 by Sapphire....

i'm waiting for any replay.. i Really want the card... and i thinking to switch it to other one.... i Hope we can fix it....

Your PSU is probably crap...I've never heard of EZcool.

You probably want at least 40amps in the +12v rail.

Driver, tried alot of them... now 8.8...
Heat... 52 max when 100% GPU Activity (40% and 60-80% when playing).
Power Supply? nope.. dont think so... i can play Crysis for 2 houers, but can't play GTA 15 min? + check the ATI topic.. the people there haveing really good PSU... what you thinking guys?

I searched for your psu, and only found sites that wouldnt translate, all others didnt have any information. Check on the sides of your psu for the amperage for both of your 12 volt rails, or combined wattage. Im almost certain its your psyu at this point

You just posted this has happened today with a different game?
August 21, 2008 5:37:43 PM

it really seems like a PSU issue. even if crysis worked earlier for awhile that doesn't rule it out. do you have the specs on it?

Your PSU is most likely not sufficient for a 4870.

here it is:





how i can be totally sure that its the PSU? i need to know cuz i thinking to switch to GTX260... tomarrow.....
August 21, 2008 5:57:00 PM

22A on +12v... i guess thats it lol. Even corsair 450 watts has 33a on +12v
a c 175 U Graphics card
August 21, 2008 5:57:21 PM

You only have 22A on the +12V rail, even assuming this PSU can actually produce that amperage and maintain it. I believe you need at least 26A.
August 21, 2008 5:59:45 PM

well, how can i be sure that is the problem?
August 21, 2008 6:01:47 PM

Yup as others said your PSU only has 22amps on the 12v, thats not even enough for a 8800gt.
August 21, 2008 6:03:05 PM

You can be sure becuse 3 people told you so.
August 21, 2008 6:06:21 PM

well, someone told me on ATI forums...

"I have a similar, if not identical problem ... Zakash, thanks for posting the video! Here are my specs:

Q9450

Asus Rampage Formula - flashed to latest BIOS

OCZ PC-8500 Reaper 4GB

2 HD 4870's in crossfire, with Artic Accelero S1 Rev. 2

OCZ Pro Xstream 1000W PSU

Vista x64 ultimate

Idle GPU Temp: ~ 50 C.

I've tested on S.T.A.L.K.E.R. as well as Furmark, and the same thing happens. Things will be working smoothly for a few minutes, and then the screen goes black and loses the signal, but the system continues to operate. I noticed the GPU temp while running Furmark just before crash was 70 C. Not exactly overheating, IMHO.

Out of desparation, I've upped my PCI-E freq. to 105, and tweaked my memory timings/voltage to the manufacturer's specs. I don't know if the 3rd party cooler is the culprit, or if there's an underlying driver issue. I've tried various versions of Catalyst, all to no avail. I'm at a loss, and there doesn't seem to be any "quick fix" out there yet...hopefully we can resolve this soon!"

his psu its bad too?

And, youre having the problems that made us think in this direction. Even tho your psu allows you to play, for awhile, it heats up, as it heats up, it becomes less effective, making it draw more power to do the same job. As it draws more power, it heats even more, after a bit of time, it all crashes

August 21, 2008 6:10:37 PM

That is a bad driver install. Have him uninstall the driver, go into safe mode, and use driver sweeper to remove all the old drivers out, then redownload/install new drivers
August 21, 2008 6:12:31 PM

Dont come ask for advice if you dont want it.

You, and him have way different setups and different issues.

His power supply sould be good but he has some obvious differnt issues then you.

His problem is most likely ram or aftermarket cooler issues.

It's totally irrelevant what that person is seeing.
The Picture of your PSU explicitly shows that it does not have sufficient amperage.
Watts are only a small part of the story.
And even there, the cheap PSU manufacturers lie.
They often list brief peaks they can handle and not sustained.

Grab the AntecEarthWatts 500 from NewEgg that is on sale and you will be perfectly fine.
That may not even fix your problem since you could have multiple problems.
But one is definitely your PSU.
Personally, I would not even turn my system on with that PSU again, otherwise all my parts may fry.

The Power Requirements for an EVGA GeForce GTX 260 is minimum of a 500 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 36 Amp.)

Your PSU only has 22 amps. Don't expect to run that card on the PSU you currently have either. Do yourself a favor, listen to everyone's advice and buy a quality PSU from manufactures like: Corsair, PC powering & Cooling, Seasonic, Antec, etc.

First of all a survey on one of the respected sites (I forget which one) showed that a budget 500 watt supply frequently can not even provide 350 watts without becoming unstable or shutting down. That PSU may not even be capable of 22 amps on the 12v rail. Secondly, while replacing the PSU is a must, it IS a new computer, without a history of being stable, so there are other possible factors such as bad memory or improper clocking or memory latency settings. Yes that may only affect some games and applications and not others.

Antec 500watt
August 21, 2008 7:07:03 PM

500w is a MINIMUM requirement for the 4870 (a GOOD brand such as corsair, antec, P&C). Don't cheap out the psu or you will regret it. You show us antec 430 and the other jewel shyt that will prolly cause you the same problems. If you know your system uses 430 watts don't buy a 430 watts.. it's stupid. You should be aware that the efficiency lowers with aging and heat so don't go under antec 500w and don't go a shyt brand.

+1 to Antec 500W.

Programs, no. Testers, sort of. Read any PSU review at Jonnyguru.com or Hardocp.com for their methodology, and you'll see that a commonly available PSU tester really can't tell you anything beyond the minimal-load voltages on the various rails. They don't test voltages under load, or show electrical noise, or any number of other things that differentiate a quality PSU from a bad one; they're really only good to identify DOA units.

Look at the specs on the page for the 500 watt psu. Your psu has 22 amps for 12 volt. Thats all. No dual rail. Not sure of the minimum for the 4870, Id guess at 32 amps minimum for the 12 volts combined.
August 21, 2008 7:30:13 PM

i got there 17 + 16? = 33 total?
a c 175 U Graphics card
August 21, 2008 7:34:08 PM

Antec EA-500:
Output +3.3V@24A,+5V@24A,+12V1@17A,+12V2@17A,-12V@0.8A, +5VSB@2.5A
The label indicates that the max combined amperage on the +12V rails is the full 34A (on most PSUs, you can't just add the rails together).

I agree. Many years ago I learned the hard way. I had a el cheapo and it fried my MB, Video Card, Sound Card, and a controller card.

I had to get MFG replacements and I was down for weeks.

don't skimp on the PSU. Even if that doesn't fix this issue it will save you from many to come.
August 21, 2008 7:47:28 PM

Where is zorg when you need him. Its probably actually a virtual dual rail like most duals are. So it might be all on one rail.

Not sure..I would research it and make sure. But That Antec 500 is pretty cheap on egg. maybe spend a little more and get 650 or better for head room but not much more..

August 21, 2008 8:50:28 PM

what you guys thinking about Corsair VX450W?
August 21, 2008 9:05:11 PM

450W man.
Just is not enough for the system you have.
I would suggest about 600W at least!!!
You could go for the 620W version of the Corsair PSU ;-)
August 22, 2008 3:03:59 AM

I have a 1000-watt Corsair psu with a Sapphire 4870X2 and I'm having the same problem as the others on here. MSI P45 Diamond mobo, Vista 64, 4 gig ram, 2.66 quad cpu, 8.8 Catalyst drivers, and HL2 and the others crash on me unless I play in a window or at 1024X768 (on a 24-inch HD-LCD that supports 1920X1200!). Everyone at ATI/AMD is telling me it's a card issue so I'm sending it back and getting a replacement. Should be interesting to see if it still happens
August 22, 2008 11:08:36 AM

ok so... i used another PSU (450watt, 25a per 12v) and the games keep crashing...

i just came back from the PC store... i picked up new card (i mean i replaced the old one).

will check that and update.
a b U Graphics card
August 22, 2008 2:47:11 PM

Ummmm, 25 amps per rail, thats a total of 50. Lets assume thats ONLY 25 amps per rail at max, and actual is 2/3's of max. thats 34. 34x12 = 408, which only leaves 3 1/2 amps for the rest of the system. Not too sure about those numbers on that psu
August 22, 2008 3:55:08 PM

anyway.. i went to the store and bring another 4870!

and you know what?! the same problem...

you can't blame the PSU, CPU, or any thing else... i tried any thing!

well, i'm will bring another 4870, but this time by another compony to check if its Sapphire problem or ATI.

btw, to wierd that on youtube and ATI all of the guys that have the same problems with 4870, got sapphire one...

any way, i will update you soon

August 22, 2008 4:09:57 PM

Well, it could ve a defective rev design... I mean, the Phenom's B2 had the TLB bug, the ATI cards could have something on their ref. design boards or something... Also some kind of problem with the GDDR5 modules, defective chips of some sort... We should wait for more driver updates that issue this problem and see what really happens with the 4870. And this is seeing the worse case scenario, wich i doubt.

Anyway, get that 500w+ PSU (i'd also say get a 600w with at least 36A combined power on independent rails) just to be sure.

Esop!

You could be the unluckiest guy in the worls, or all the other owners of the 4870 have just been lucky. Make sure youve taken every possibility in check before you again blame the card. I find it hard to believe, after 2 cards youre still having problems, and after three, the problem simply is not the card
August 22, 2008 4:41:50 PM

Then it could be a rev. design problem or a chip choice from Sapphire. Try other manufacturer and see how it goes.

Did u get the 500w PSU? I mean, it could also be that your current PSU is damaging the cards at some extent :p

Then u have your answer there.

U can wait for a second rev of the card or just get another Vendor... Remember they ship in groups also, so it can be that particular group that got a manufacturing problem. Don't blame it hard on Sapphire, cause it is one of the best manufacturers for ATi out there. Just bad luck on this one.

And yeah... Remember getting that PSU, so u don't have problems =)
