the price may not drop soon, cos it was dropped in last week or something like that.
your psu will handle that easly

Thanks, yea you're right. I totally saw that price drop, and my hopes are high for another in the next few months. All I can do is hope hahaha.

Hi, just wondering if anyone else has a Gigabyte 6870 Windforcex3 (with the 3 fans), and has it overclocked?
Also would there be a good gain if i did get it up. Idle temp atm is about 32, Load goes up to 60 on 3dMark Vantage. Though Ambient temps are about 16-17 atm.

The limiting factor on my system I think are the Harddrives. Do they bottleneck performance in any way?

hard drives can only delay the start of something. loading times, system start up. they dont have such big influense on computating itself.

The ECC memory kept working fine, and they don't seem to test memory overclocks well enough (even OCCT doesn't). For some reason, being in a game that constantly had to update what was stored in the vRAM caused huge stuttering at times that I eventually put down to a vRAM problem after a half hour/hour's stress testing followed by benchmarking in the Heaven Benchmark at different overclocks.
I did say 30 minutes. And yeah for memory sometimes games are necessary for checking performance decreases with unstable clocks. Atleast it is easy to figure out what is happening when your being throttled.

Just waiting to see if they 6870s drop a LITTLE more in price before swooping the 2nd =P
I have been told several times by reputable members that my 650w will be enough for 6870CF with my build and your 750w should be abundant.

no your hd will not bottleneck you at all. those are good temps too. like i have said, the windforce card is awesome...would just be sooo much better with voltage control.

Hello everyone:

I just bought a pair of this babies Sapphire Radeon HD 6870 And no matter what I do I cannot overclock the memories past the default 1050 Mhz.

I'm wondering if it is because there are certain speeds that the memory won't support and I have to go further or if it is because this card (not being a refference cooled car) just won't admit memory OC??

Or is it that you have to up the GPU voltage to overclock all the values GPU and Memory?

Any help will be appreciated.

Martin.-
