Nice post^

Does the VT1165MF need to be cooled?

If it can be, then YES!

[CHRIS_666]

My result: Intel Core I5 750 2.66@ 4.546,5MHz + ATI 5850 (GPU: 1020 / Mem: 1300) = 19554 (3D Mark Vantage)

Hey can u tell me how to do that? I cant seem to figure that part out.

See here

[KoHaN69]

overvolting seems absolutely useless on air.

the performance gain is minimal:

Anyone know if the MSI GDDR5/ATI HD5870/Military Class 1024MB / Extreme Design Lightning II R5870 Graphics Card is compatible for HD 5870 CrossFireX Asus standard - the standard XFX.

Thanks for the advice, is that I have two HD 5870 and a friend wants to buy two HD 5870 MSI Lightning II

Thanks

Is this thread alive?

I can't pass 1055MHz on core with the spitfire installed, i don't know if is a problem with the BIOS, vCore :S...

[zpaf]

Added 3rd 5870 in my system and this is the result with 1.3v

[demowhc]

nice score, I just broke 36k with 3 x 5850

[Gaul]

My ASUS 5870, just need Vgpu 1.187 for 1 GH core

[icetink]

xfx 5850 xxx edition
memory sucks - can't go higher than 1160MHz

[situman]

So SCII on ultimated settings at 1680*1050 res brought my system to its knees. My system says low on ram. You guys think its a vidcard not powerful enough or I need more system ram? 4gig + 1 gig on 5870.

my single 5850 asus 1,28V on air but EK is comming

not really sure what's going on there. my laptop with a 4870x2 card and a Q9300 OC'd to 3ghz and 6gig ddr2 800 mem runs SCII on full everything @ 1920x1080 without issue... and my tower, well it just laughs at SCII's highest settings so... could be a driver issue maybe?

This is a full AMD platform. Specifications are in my signature.

Need more ram supposedly, at least thats what window tells me. My ram is low.

3 gigs is needed to keep from using the Pagefile.
Running 4 gigs here.

I have the unfortunately not software overvoltable Gigabyte 5850OC, but despite that I seem to be able to run 925/1300 stock. I guess that's good enough. Running furmark for stability. I find it unusual that the RAM can clock so high, but I can't see any performance drop that would indicate ECC kickicking in. It just keeps going up. I wonder if there's a hardware voltage mod for this board? Be interesting to see what it can do with some extra juice.

UPDATE: At 925Mhz core I got rare GPU crashes, but 900 is flawless so far.

[zalbard]

Is anybody using this BIOS? And how is it working out for you? Seems to be the latest revision available, unlocked also...

nice, reference or DirectCu?

Xfire 5850's w/stock cooling.

haven't tried it. any testers? I'm still on the last one that we had from many moons ago.

Well, I finally got my 5970 crossfir system watercooled.
So, I can't get it any higher than this, with a combination of the ati overvolt to set the memory to 1.15V and msi afterburner to set the gpui voltage to 1.25V.
Temps are good (max 45C on the GPU and 80C on the VRM's with furmark)

When I set up this system at first on air, I was in the top 60 on Vantage...it took me a while to get the watercooling going and even though I am lots faster, I';m now in the top 80-90! Oh well....

Here's the results:

[Dahaka]

Finally pass de 1060MHz wall

[Loque]

gotta spread the word..

there's a "new" tool from sapphire called trixx for 68x0/69x0 cards that works on non reference 58x0 cards, can finally increase voltage !

saw this at tech power up, link for app:
