Has anybody tested 2x38x0 cf on the p35?
How big is the performance impact comparing to normal PCI-E lines (8/8 or 16/16)?...
I know that anandtech doesn`t recommend CF on the P35 due to performance loss (x16/x4 and immature drivers) but the tests were done with 2900XTs... and what`s the situation with 38x0s and current drivers? Has something changed?
any info?
Hmm.. 7.11 drivers are out, but no mention of crysis or cod4??
edit: just found this on techspot..
AMD has released an update to their Catalyst software suite, bringing the package up to version 7.11. This latest update focuses on stability rather than performance enhancements, according to AMD, fixing bugs in BioShock, Call of Juarez, Enemy Territory: Quake Wars, Hellgate: London, and a handful of other titles.
The new drivers are available for Windows Vista 32-bit, Windows Vista 64-bit, Windows XP 32-bit, Windows XP 64-bit, Linux 32-bit and Linux 64-bit. AMD does advise, however, that Crysis players should stick to the Crysis Hotfix drivers released a few days ago.
Yes, was posted yesterday.
But can't be posted enough. :)

ATI Set to Launch Offensive with ATI Radeon HD 3000 Pricing.
ATI Radeon HD 3000 Has Enough Pricing Flexibility – Sources
ATI, graphics product group of Advanced Micro Devices, may lower the pricing of its ATI Radeon HD 3000-series graphics processing units (GPUs) in weeks after the introduction in an attempt to recapture the lost market share from the No. 1 discrete GPU supplier Nvidia Corp. The decision will allow add-in board manufacturers to decrease the prices to end-users.
“Two weeks after the launch, the ATI RV670 drops the price,” a source familiar with the matter told X-bit labs.
The ATI Radeon HD 3850 with 256MB of GDDR3 memory begins at $179 manufactured suggested retail price (MSRP) and the ATI Radeon HD 3870 with 512MB GDDR4 memory from $219 MSRP, available from AMD’s selected graphics products partners. Unfortunately, not all suppliers of graphics cards could get the new boards on time from AMD.
Price reduction of the already not very expensive ATI Radeon HD 3800-series boards is likely to help AMD to capture attention of many end-users seeking for a new high-performance graphics cards for Christmas. Since the new lineup of graphics solutions support both DirectX 10.1 and high-definition video playback, the features demanded by end-users this year, the novelties truly have chances to become popular this holiday season.
http://www.xbitlabs.com/news/video/d...0_Pricing.html
Looks like the 55nm manufacturing process is turning out quite nicely for them
Well certainly. I'm still hesitating: shall i wait for the X2 version, or buy 2 x 3870 and be happy now. BUT it is not even available at Komplett!!!:mad: Yeah, they had a few at launch date, but now they say availability January! :(Quote:

To not even mention the shops in my town, not one has the 3780 in stock...
Lowering the price is nice, but p[lease AMD/ATI: deliver the card asap! :(
they're hitting newegg here and there... but they're gone faster then they came!!!
new egg isn't getting any in it is the morons who put them in their cart hoping to talk mommy into buying them , then after 72 hours when the cards aren,t paid for the egg returns them to stock. that is why all the new stuff sells out so quick ...they never even leave the warehouse.Quote:

I'm glad I've got 2xHD3870 for 133 pounds each but looks like shortly they will be even cheaper! :)
i think next week lot of them in shops :up:
regards
will next weeks version be shipped with the latest bios (not that it matters just quite interested)
More than likely. I think I read some where that all new cards will be shipped with the new BIOS update. Considering all the cards are sold every were, the new stock must be the new cards + BIOS update.Quote:

so it only read
'full directx 10'
is there an issue with this? or is it just done because the .1 isnt out yet

My first post in this thread...but here is what I've got so far...
Q6600 G0 @ 4.0Ghz (445FSB)
2GB G.Skill DDRII @ 890Mhz 4-4-3-5
2 x Sapphire Radeon HD 3780's (stock clocks)
My CPU and both cards are liquid cooled. The cards are idling at 29C and 28C so I should have plenty of room for overclocking. The BIOS are flashed so I can surpase 860Mhz for the core. Catalyst 7.11 installed.
Starting Point - 3DMark06 - 19,796
For those of you that is not using the stocking cooling solution, how are you guys cooling the digital pwms on these things?
great scoe for Crossfire Default :up:Quote:

A crossfire HD 3870 system spends same as a 680i + single 8800GT.
^^Interesting indeed.
Finally a review with 2 different mbs. The results make it pretty obvious why all reviews should use this method (if they can).
This also puts into prospective the cost factor of 2 3870 vs 2 GT and the performance associated with them.
Where is my second HD3870?? :D :D
I really love the power consumption.
nice :D
does the zalman vf900 fit on the 3850 or 3870?
awesome!
Any that fits the x19xx's works i believeQuote:

That is huge improvement under load, but idle is amazing too! It's better (lower) with two cards than what it was with ONE HD2900Pro(XT) :up: !
Me getting my Sapphire HD 3870 in few days, Play.com finally shipped it to me.
Hehe I´m also monitoring power consumption with my Gigabyte Odin (yes I know, weird system, and inaccurate) but my system with the 2900XT idles at 150W, with an X800 at 100W, and with 3870 100W too! Impressive. And loaded, 2900XT 330W, 3870 only 235W!! More impressive. In a few days I will test 3870 CF.Quote:

in single card set ups. Xfire gives more benefit than SLI atm, however, and shifts that list more towards ATI's benefit in multi GPU set ups.
I'll agree with that for the most part, except for your last comment.Quote:

Scaling looks pretty good from the Radeon HD 3850, however it's still not as good as what NVIDIA is able to achieve with the 8800 GT. NVIDIA consistently achieves about 11% better scaling from one to two GPUs than AMD.
Its comparing the 3850 to the 8800GT a little like comparing apples to oranges. A better comparison would be to use two 3870s, which from what I've seen just on this forum, the 3870 in crossfire out performs the 8800GT in SLI. Have to be impressed with these scores.

I could be wrong. I was relying on the following:Quote:

which is more extensive than the Anand testing and seems to show the CFed 3870s more competitive against the SLI GTs than the single card comparison. Drivers and i780 could certainly change that though.
That was going by scaling percentage, NOT performance percentage.Quote:

Also, have we still not learned that 3dmark scores don't always translate into gaming performance? :confused:

Now that doesn't make any sense. The 8800U somehow becomes 20fps faster when going from 1280x1024 to 1680x1050? And there is no way that the GTS320 will be beating the GT512 in any benchmark. I have to question that review, those results don't look right at all.Quote:

More intresting performance comparisons...
Computerbase - updated article
If there was any flaw in 2900 AA or AF performance it's been magically (and completely) repaired. And 3800 improves that a little. ;)
Driver version or source thanks? :) Only if it's the latest beta I won't directly write "biased" all over it. I don't think it's possibly to fix it by drivers though but that would be nice. Too bad for ATI though if they've had to sell 2900XT this cheap only since they hadn't gotten out a decent driver in time...

All the charts are flawed in their design when you use a percentage from the original value.Quote:

That 2600XT score is weird so im not sure i trust that review, but if true i got lucky that i picked the hd3870. Why would the 8800 series have such trouble displaying content at 1680x1050 though?
Well almost all 20'-22' TFT monitors have a native resolution of 1680x1050. Thats currently a rapidly growing market and i really think reviewers really need to give it more attention. On the other hand 1920 and above resolutions are quite rare still and flat panel monitors that can display them cost $600+ so they are not going to become mainstream anytime soon.
Umm.. i think 1920 x 1200 is the rapidly growing market. 24" widescreen is becoming affordable. IIyama 24" Wide ProLite B2403WS-B1, Zwart, DVI-D/HDMI/D-sub, 2000:1, 3ms € 413,00 but €399,- already in shops in my town. If i were to switch to a flatpanel right now it would be that one.
So? I wasn't directly comparing the two - I was giving an example from possibly a more legitimate source.Quote:

Hey guys I have a question I just jumped into the post that seemed close to what im looking at. I have a p5e (x38 chipset), e6600, Plus I just purchased and recieved 2 3870's for crossfire. I have 3 monitors. what is the best way to configure my setup. i want to use the crossfire of course i also want to use my third monitor can anyone help?
Hi guys
what you think
2x HD3850 512MB PCS edition (720/1800) with samsung 1.0ns and cooler (Today )
>> http://www.powercolor.com/pt/product...ProductID=1660
or wait 5 more days for 2x HD3870 ??
i think the HD3850 512mb PCS edition +- same thing ............ (less 2-4 FPS in games than HD3870 )
:up:
You tell us. YOU have the cards, so also 2 versions of manuals with them, a paper and a software version, plus the CCC...Quote:

done
tomorow 2x HD3850 256mb just for 5 days then :
2x Powercolor HD3870 PCS Edition >> http://www.powercolor.com/eng/produc...ProductID=1647
jan/Feb change for HD3870X2
:D
:up:
Are you mad? and/or filthy rich? and/or joking? :eek:
Well, you test them then while i watch and wait! :clap: (and save!)

I look forward to seeing how the Powercolor cards run with the 3rd party cooler. I'm not finding the 3870s to be hindered by the stock cooler. Maybe on the memory side but not on the core.

So I'm using 2 3870's on a p975 chipset. So far my 3dmark06 scores almost hit 16k with an e6600 running at 3.6. I see also higher framerates in every game at 1920x1200 than a 2900xt. How much more performance increase am I suppose to see with a x38 chipset?

:up:
Yes, that would be very nice, I just wanted to see if anyone was using the same configuration but swap out the board to an x38. I love the cards, they are blazing fast!
The dilemma I have is that I have a few Q6600's ready to go but I read that the 975's can't handle the quads very well. Wondering if I should just sell them, make a few dollars or 2 and wait for the penryn's or upgrade the board now. If the 3870's are much fast on the x38 then that makes my decision a lot easier. :)
Ditto.
I get them in two weeks as well
nice, just curious what's the availability on these cards nowadays?
I think the wife ordered the 3870's through Frys @ 224.00/ea w/ 20.00 rebate. Availability is 2 weeks- or so I'm told
Any problems running CF guys? All the games you can try actually take benefits of CF?
Waiting your results mascaras. Also, when you have the cards, some 3870+3850 would be nice :D
I can tell you that running these cards in CF is a big improvement over a single 1gig 2900xt in all games I play, cod4, crysis, the witcher, etc...
Have you tried OpenGL games?
