I have two new Sapphire Vapor-X 1gb 4890s in CF and whenever I try to overclock the memory speed in catalyst (version 9.8) my screen turns black with white spots. My core speed oc’d fine and the fan control works. The same thing happens when I do auto tune aswell.
Looks like the only solution is to give it to me. Sorry buddy.
Seriously it looks like either it’s too hot or you’re just pushing it too far.
This now happens whenever catalyst starts up for the first time after loggin. It only works when I start it up after a reinstall.
That just means Catalyst remembers the values you try to set on your card. The solution: Don’t try to overclock too much your card. GPUs are not made to be OC’d.
I did a clean install and didn’t touch the values and it still happens when i restart.
Does it happens before or after Catalyst starts?
It happened when catalyst started, but unfortunatly they just died on me. They beeped during startup and then died.
FML
Yeah looks like you killed them. Sorry man.
Just ordered some xfx ones to replace em. Looks like they got better reviews, but they also cost more…
I have to ask, Why overclock hardware? My rig has a Core I7 d0 stepping 2.66ghz CPU and also a HD 4870 X2 GPU.
I have OC’ed the CPU to 3.5Ghz to see if I could do it and it was simple but the thing is, the stock speeds easily play crysis on all very high settings.
Im not here to brag but to make a point. When you spend the amounts of money we clearly all do on PC hardware why OC it and take the risk of breaking them?
I read Custom PC mag its my bible and they gave the vapour X an awesome review in fact I was gonna buy one, they look cool too…
If I “could” wait a few months Id buy a DX11 card as theyre only around the corner.
Well Hydroz0rz, unless you are a moron overclocking gives added performance with no cost other than your own time, with next to no risk to your hardware. People who screw up their hardware when overclocking aren’t doing it correctly, or intelligently. I’ve been overclocking hardware for years, and I’ve never killed hardware because of it because I research, monitor, and test. I never buy top of the line hardware. I buy gems that have a lot of overhead for lower cost. This allows me to get great performance without paying a premium.
Crysis isn’t a benchmark program, and doesn’t show gains based on typical hardware performance. I have no idea why you mention it at all. Encoding programs and highly CPU intensive tasks are why I overclock my CPU. Games are why I overclock my GPU. There is little to challenge my video cards, but there is some, and the extra bit of overclocking allows for either slightly smoother frame rates in some games, or allows an extra visual feature to be turned on without decreasing the performance.
That’s why people do it, and none of what you said makes any sense.
Such an agressive reply.
I dont quite think you grasp what i am saying. It does not matter if your intelligent when your OCing because basically when you go higher than default frequencies the hardware can go BOOM. Im not saying it will Im saying it can. So yes there IS risk to your hardware.
Crysis is the most difficult game to play to date on all very high settings with custom CVARS to make the game ultra high detail. So it IS in fact somewhat of a GPU Benchmark.
Crysis is a benchmark of sorts, as in you can run it to compare how well your computer runs now versus previously, but it’s not a very good one. A real benchmark program actually gives you numbers and such to let you know your performance down to each individual piece of hardware, which is a much better tool then running a game and saying ‘yep, this sure looks better then before’.
You can use pretty much any new game to benchmark, so saying that crysis is the best, or even a good one, is flatout wrong.
I didn’t break em cause I OC’d them. That particular model from sapphire had a defect that causes it to die during startup, but the screen freezes and crashes when catalyst started might have been because of me trying to OC them. The card came at 870/1050 and when I first tried to OC em I brought them up 930/1120. The highest I could’ve brought them would be 995/1195 (wouldn’t dare even trying to bring em 1000/1200). My new XFX ones are coming today so im hoping nothing goes wrong.
I personally cannot think of a DirectX 10 game that punishes a GPU like Crysis.
I never said it was in fact a benchmark, theres loads of progs for that!
Crysis IS NOT an accurate tool to determine performance increase or capability comparison as increase in hardware performance or power doesn’t correlate to increased performance in Crysis. How much it punishes hardware is irrelevant. If you throw a lot of processing power at something and then less with no realized difference, that means as a metric it is not accurate.
There is a risk that stock clocked hardware, or less than stock hardware will ‘go boom’, as you say. However with proper understanding of the hardware involved, and understanding the operating specs of the components, proper monitoring leaves the risk involved with overclocking at about zero increase over risk at stock. This is, again, assuming that there has been no ill advised maneuvers along the way.
I think it’s a good thing that you killed your cards while still on warranty, they might have failed eventually if the ram was so sensitive.
The two new XFX ones preform perfectly. Got them to 945/1120 without a hitch in catalyst 9.8, the preformance increase over my two old 4850s is insane. The only problem I have is that when the fans are at 50% or higher they get really, really LOUD!
then buy a Watercooling system
Why would you want to overclock a 4890, i’ve got one and it runs fine, it only slows down at times because you’re stressing it out, like playing crysis.
