Can i 16 * 4670 + 4 * 4670

[myowaiwin]

finally i got 2 gigabyte 4670 1 GB ddr3 for 2 pc (after very long condieration with the help of Tom Hardware advices)

my mobo is H55S2H Gigabyte with 16 * pcie + 4 * pcie CF (software only)

so i have a chance to test CF (i have never been)

so, plz let me know how to make software CF? (i detail step please, as i've never used 2 card in one pc)

and will it be benefit for me to have with 16 + 4. (i read some post that 16+4 is not suitable for CF but i just have 16+4) or just 1 card is better than 2 cards?

thanks to all

You should be fine for crossfire..the 4670 doesn't need that much bandwidth. For software I'd assume you install the drivers from AMD/ATI with both cards inserted.

 

[myowaiwin]

what do u mean by bandwidth and what should be the optimal value.
where can i look at ?

thanks

 

[dubstep]

Bandwidth is whether the pci-e slot would be able to transfer all the data back and forth to the graphics card without a bottleneck. There are loads of guide on the internet of how to set up crossfire just google it as with most things. I cant say for sure but seeing as u have both the cards you should experiment as thats where the fun lies usually. If you dont notice a performance increase just take the extra card out.

Your motherboard is PCIE 2.0 so a x4 really shouldn't limit an HD4670 I would think. Just install both cards and enable crossfire in the Catalyst Control Center.

Yeah, it should be fine. Either way nothing wrong with running a bench test before and after.

You really should see a vast improvement though and I don't see why you wouldn't.

 

[myowaiwin]

with CF of two 4670, i see little improvements (about 15-20% increase FPS)
it's less than my expectation (it should be 100% imporvemnt right?, and may be above 50% will be acceptable for me.)

so it's better to stay with single card alone.

thanks

 

[jyjjy]

Is it really that low? You should be getting around a 70% increase I believe. What did you test with?
Also what processor do you have and what resolution are you using?

 

[myowaiwin]

i played with WOW dota with max resolution and all high setting.

so i'm wrong on CF. i just make in CCC.
or WOW have just low graphic requirement for even 1 4670
or my 4* PCIE is bottling neck my both cards?
or my FRAP software is just wrong with WOW?


thanks for ur reply.

 

[myowaiwin]

my current PC is

i3 530 3.3 OC
2GB ddr3 kingston
500 gb western digital
h55 mobo

i'll just use 1 card for my pc, 1 for my bro. i'm just testing how CF work for future upgrade

 

[jyjjy]

From what I'm reading WoW does not really use Crossfire effectively. If that is the only game you play then it isn't worth it.

 

[myowaiwin]

my current games are

WOW
COD 4 : MW
COD 5 : world at war
N4S : undercover (i'm not sure, it's version before shift)
counterstrike 1.6

and my monitor is 1440*900

so i think i should ok with one card only.

may be i'll buy some higher graphic card with some more modern games

i'm little tight budget these times

 

[jyjjy]

Two cards should help you much more in the other games.

 

[myowaiwin]

finally i manage to get sapphire 5670
so i'll give my 2 * 4670 to my bro
think, which will be better between 1 5670 512mb ddr5 and 2 * 4670 1Gb dd3.

thanks for all

The HD5670 will probably be better in WoW and other games that don't really use more than one card. The 2 HD4670s will be better otherwise.
