Hi folks,

I just got my Sapphire HD 4850 yesterday, upgraded from a 8800 GTS 640mb.

It's idling at 80 degrees Celsius..

Today I am fitting my Zalman VF900 on it to see how it goes...

I finally fitted my Zalman Vf900 on my hd4850:


I dropped my Low Yat to get additional RAMsinks. I took a couple of hours to get the fittings perfect but it was worth it.

Now its idling at a cool 44c.

I'm running it at about 80% fan speed for now, there's a nice hum to it, not too loud. I ran ATI overdrive and got 690MHz core, 1188MHz memory, with temps reaching a maximum of 57c..


I am one very happy owner!

Hehe....well the overdrive said it passed..

I played The Witcher for a couple of hours at those settings, no problems yet.

Thanks. I'll probably tone down the memory speeds later, but the temperatures were so good I couldn't resist trying.

Yup it's a Sapphire card. By the way this is the first time I'm using an ATi card. My previous cards were Geforce 4 Ti 4200, and the 8800GTS 640mb.

But the 4850 is pretty awesome for the price!

Maybe. But my power supply only has one PCIE power connector and I really don't want to change power supplies, so I had to stick with the 4850 and try to have some fun with it!

I could? Damn!

Anyone want a 4850 with zalman cooler?

Hehe..just kidding.

Significant improvement? Apart from benchmarks, I can't really say.

The 8800gts pretty much ran my games fine, and to be honest I could get along perfectly with that card now.

But I got the upgrade bug, and I found a buyer for my old card, so one thing led to another...

The vf900 costs RM 159 @ All IT

Guys,


Here's a fix for the 4850 temperature issues. I found it at: http://forums.guru3d.com/showthread.php?t=265745



Copied from the page:

if you make a profile in catalyst after turning on Overdrive( make sure clock and memory settings are correct). You can then go to the file "C:\Users\Bretware\AppData\Local\ATI\ACE\Bretware. XML. the xml file will have the same name as the catalyst profile you saved. right click and hit edit.

<Feature name="FanSpeedAlgorithm_0">
<Property name="FanSpeedAlgorithm" value="Manual" />
</Feature>
<Feature name="FanSpeedRPMTarget_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="FanSpeedPercentTarget_0">
<Property name="Want" value="65" />

Change the value to "manual" and Want value to "65"

Save the file then reload your profile in catalyst.

The problem with the 4850 is that the stock fan is locked at like 22% or something.

This mod seems to work for the guys on that thread. Looks good if you don't want to spend money on after market cooling mods.

Glad to help.

Have you tried it?

Try enabling "Show system and hidden files"..

Awesome.

How's the noise like at 54 degrees?

It should. Why don't you try and see?

One of the forummers on Guru3D said 65% had acceptable noise.

hehe..

I don't know why ATi engineers locked the fan speed so low. Is it to keep the noise down?

3rd party Coolers are great if you know what you're doing and have the money to spare.

But hacking the hardware invalidates the warranty, and if you're not careful you could mess things up doing the installation.

BTW, I installed a 3rd party cooler


But the guru3d mod is perfect for those reluctant to mess with things. Oh it saves money too.

It doesn't void the warranty? That's good to know, especially for me.

I really didn't want to spend extra on the 3rd party cooler, but then I remembered that I just paid half price for the hd 4850 after selling my old card, so I thought what the hell man, live a little.

If it comes to that, I suggest you invest in a good pair of headphones!

You think AMD doesn't have anything to do with Israel? http://www.moit.gov.il/NewTamatFiles/1D8E9...1981759DF9.html

No 4870 but here's a screenie of my 4850:

Thanks. I slapped a zalman vf900 on my card. It lets me oc it to 700/1100 for now, and its running stable.

xen0,
I don't know why it doesn't detect my fan, or what's up with all those sensors either.
