Of the new gaming rig? 130w idle, huh? I'd think you could get that down to 110w even with the dual 5870s. What is it? The high-speed fans? The fancy lights? The jet engine???

sorry I replied to this but I guess I never submitted the post "p

from what I can tell 50w+ is the 5870's idling.

I got some more stuff in the mail yesterday to complete the setup. hopefully tomorrow I can get it 'set up' nad get more pics

Actually, you did post, and I read it, and now the post is gone. Spooky! Either that or I was reading your mind somehow. Even spookier!

You said the 5870s idle at 54w, and that you hadn't worked on the idle power use yet, and that you were getting some more stuff later in the week (and now you have it!).

Wow, I think I can see the future. 🙂
 
I decided to see what I could get out of my HD5850 overclock, and I thought some of you might find this interesting. I have a lot of data here, and I think this may be of help both to those who are overclocking their HD5850, and to those who are generally interested in scaling with core/memory speed, voltage, and power use.

Test was at 1920x1200/4xAA/16xAF/HBAO, in a single-player game (for consistency).

725/1000 Clock
50.8fps
1.0v core/232 watts (undervolted for the heck of it - doesn't save much)

755/1125 Clock
53.8fps, 6% higher than stock with 4% higher clock and 12.5% higher memory
1.087v core/238 watts (2.5% higher than stock)

850/1200 Clock
59.6fps, 17% higher than stock with 17% higher clock/20% higher memory
1.087v core/267 watts (15% higher than stock)

925/1200 Clock
62.2fps, 22% higher than stock with 28% higher clock/20% higher memory
1.15v core/292 watts (26% higher than stock)

935/1225 Clock*
63.6fps, 25% higher than stock with 29% higher clock/22.5% higher memory
1.15v core/296 watts (28% higher that stock)
*FYI - I ran a 37% fan with my reference cooler and leveled off at 71C at these clocks. I had one crash at this speed, however, so I've backed it down to 925 core.

Because I'm adjusting both core and memory, you can't do a straight core clock analysis, but I think you can assume that if you increase both the core and the memory proportionally, you will get at least 75% scaling with clock increases. That's pretty amazing, I'd say. Sadly, I've run out of memory headroom, even if more voltage would up the core clock (I don't want to go higher actually, for power/temp reasons). The system power draw is almost proportional as well, with spikes as I change voltage. Keep in mind this is for the system as a whole, so in fact the FPS is not scaling directly with VGA power. You definitely pay a penalty in watts as you go for higher FPS. I might post this to the VGA forum, but I thought I'd show people here first, since I did this all to get more out of BC2.

Big shout out to MSI Afterburner, which allowed me to assign my five tested settings to hotkeys - very helpful!

Kudos for the research :thumbsup:

I turned 2 of my settings from high to med(2 texture detail settings) and holy crap. I tried to see the differnce playing MP and I cant, but the FPS bump suuuuuure is nice. I still havnet done a shader unlock on the 6950, or an OC
 
I might have said this before but I'll stress it again, the class specific weapons for Vietnam aren't very well balanced, there's a clear cut "best weapon" for each class even though there are only 3 unique weapons per.

Assaults: AK47 - assault is really the only class where the weapons are close to being balanced, but the AK47 really is the best overall. The M16 is just too weak at long range and the M14 is too unreliable at longer ranges and is really crippled by its 20 round mag for engaging more than 2 targets.

Medic: XM22 - 200 round mag (vs. 100 of the other LMGs) and rate of damage is much higher than the other LMGs, its no contest here. It almost makes me laugh whenever I see someone express the idea that the M60 is the most powerful or is somehow overpowered compared to the XM22.

Engie: PPSh - not even close here, the PPSh outputs a ridiculous amount of damage, especially at close range (but higher across the board compared to the M16), and thus actually competes very well with the assault rifles but is also an excellent hip fire weapon because its an SMG, it really is a pretty OP weapon as it can make the engineer the ultimate skirmish class instead of a support role.

Recon: M40 - the auto snipers are just about useless for anything but anti M40 sniping or engaging Hueys - they'll rape through a helicopter as if they're a wet paper bag. Problem is that the M40 is just so much better against infantry its hard to justify choosing one of the auto snipers over it.
 
In case anyone was curious as to the differences in the sniper rifles in Vietnam, particularly the auto snipers considering they handle identically and put out the same exact damage, the only difference between the two auto snipers is their scope. Aiming from the same spot at the same target we can see clearly the difference as I rank them in order from least zoom to greatest.

M21 -> M21 + 12 -> SVD -> M40 -> SVD + 12x -> M40 + 12x

2m2112x.jpg

5svd12x.jpg


6m4012x.jpg


So as we can see, it would be pretty silly to take the M21 + 12x when the SVD is nearly the same thing (it actually provides MORE zoom) and thus an alternative perk such as light weight pack for faster movement or extra ammo (particularly useful when considering the auto snipers will quickly chew through their ammo) could be paired with the SVD to do the same job as the M21 + 12x, although the M21 does allow for greater peripheral awareness, and I do prefer its sights

Did anyone with a 5xxx series card notice input lag when upgrading to cat 11.2? When I upgraded drivers and turned on MLAA, there was *noticeable* input lag from the mouse. Even just standing still and spinning around has a noticeable lag.

Anyone have suggestions?

There were two unoffical Anandtech servers, but both have since been taken down, due to the cost of running them and low player counts, I believe.

Maybe we should resurrect one? I'll put one up if people from here will populate it.

What's the best company that has hosting?
 
branzone and hypernia seem pretty good.

I would wait to see if homefront is any good though since its only like 3 weeks away 😛
 
Yeah, after finishing platinums on the M60 and RPK, those two LMGs are actually relatively balanced, the RPK's higher ROF and slightly better accuracy and iron sights make up for its lack of damage relative to the M60, but the XM22 is just super OP in comparison to both, I'm glad I can just whore the XM22 now that there's no more medals to be won when I'm playing medic.
 
I've gotten so bored with this game. I only played Vietnam for like 3 hours in total since it came out. I don't know why but it's just not fun to me.
 
Hey guys, I just upgraded to an eyefinity setup and finally had to move off my old reliable drivers to Cat 11.2. Never had any ctd problems before, but now I'm consistently getting ctd after 5-10 mins of game play. Any suggestions? I'm running a 5870 1GB right now fwiw.
