Re: Worth replacing MSI Cyclone cooler?

You could simply replace the fans with slightly larger slim fans that are controlled by either your motherboard or a fan controller. Alternatively, Accelero S1's fit on some GTX460's. You can then attach slim fans to the top card (b/c you won't have much room). You'll also need to purchase a longer ...

Re: Asus E35M1-M Pro: AMD Fusion Motherboard

Excellent review. I have been following the various previews of the bobcat variations with high hopes that they could meet my htpc and/or home server needs. The current iteration doesn't meet my htpc needs but it may serve as a worthwhile replacement for my whs. I have a few questions and comments. ...

Re: Radeon 6850 Undervolting Survey

What is the speed of the fan at idle without software adjustments? I'm getting the same minimum speed - 1070 RPM - but only barely, as it's at 27% now. Fortunately, the card is whisper-quiet up to 36%, so I'm not worried about idle fan speed even in summer. I'm aware of micro-stuttering having prev...

Re: Radeon 6850 Undervolting Survey

Do you have multi-display enabled? When using multiple monitors (or perhaps even having it enabled....I haven't tested either way), the card's downclock is less (300 300, iirc). I believe the standard single monitor downclock is 100/100 or 100/150 (I'm not in front of the PC with the 6850 at the mo...

Re: Radeon 6850 Undervolting Survey

(1) After flashing your card, please confirm that the voltage downclocks while in 2d mode (.945) and then switches to 1.006 for 3d mode. Yes, it does. (2) Fan control no longer works after flashing the bios? Your previous posts indicate you had no issues with fan control prior to the flashing. Soft...

Re: Radeon 6850 Undervolting Survey

I have already flashed my card. The only issue was that WinFlash hangs the PC after flashing, so you have to restart it. :shock: :) Other than that, it worked. I set 3D voltage to 1.00625V. Well, actually, I initially set it to 1.006, but if you reopen the BIOS after editing, you'll see that the ac...

Hey. Having the same issues with the Asus DirectCu as you have discussed in the last few posts. At 20% (and 25% actually) the fan wont go below 1800 RPM. Turning it further down in MSI Afterburner has no effect. Doesn't sound like a rare occurrence at least. Sounds like a card to avoid for those lo...

Re: Radeon 6850 Undervolting Survey

According to that article, the Asus card idled at 1560 RPM (and that's at 38C, so it may be the actual hard limit). Nice catch. But it doesn't explain why Givorg's card will not go below 1900rpm. The article also states that the cards idled at the hard limit of 22% of max rpm. I think you will find...

Re: Radeon 6850 Undervolting Survey

The card will not lower the fan below 1000rpm (or 25%). This is the hard limit set in the bios. Don't you think the Asus card could simply have a different hard limit? I asked for the make of the card for this very reason. After learning the card, I discounted that possiblity b/c of the SPRC review...

Were anyone able to lower the idle fan speeds below 1900RPM? Asus SmartDoctor cannot go below 22% fan speed. Also, at idle speeds (i.e. 2D mode), do you notice any whining noise from the GPU fan? Not sure if "whining" is a correct word, but there is some other sound in addition to the typical turbu...

My Sapphire HD6850 exhibits coil whine, too. It doesn't really bother me because it isn't that loud and only happens under load, so even my open headphones mask it. But, no, coil whine isn't a GTX 460 thing. Agreed, 460's generally do not exhibit coil whine. It certainly was with that particular EC...

After a few laps in Dirt2 I'm getting 65C at 2150rpm with stock settings (voltage and fan speed) and 64C at 1500 rpm with modified settings. Even stock settings are quite tolerable, but undervolting makes things even better. And there is quite a lot of room for adjustments - I could set higher temp...

My fan profile is based on two points: 20% at 40C and 50% at 80C.

But now I'm getting approximately 43% at 70C, and the difference between 50% and 43% is very noti...

Interesting. I figured that such an undervolt in 3d was unlikely (and thus didn't mention it as a possible occassion that would nullify my conclusion).

Re: Sapphire Radeon HD 6850 very silent and not even vapor-x

My primary concern with video card noise has always been the noise at idle. I spend 95% of my time using my PC for mundane desktop tasks. And, if it's quiet at idle, it will likely be quiet enough to be drowned out by sound while gaming. I join fellow members lauding the quietness of the Sapphire Ra...
