Hi,
I have a very old mainboard with only 1 PCIe-Slot. And only a ATI Radeon HD 4350. The hash rate is very weak. 7.5MH/s.
Most of the good actual cards are 2 Slot-Cards. I can´t install them in my old shitty computer.
But I found a ATI Radeon HD 5770 Single Slot card. Have anyone installed this card?
How many MH/s?

PS: I´m only 14, and german. Sorry for my english.

I have this exact card. I get 180-200 MHash depending on overclocking. Performance will be the same as for a dual slot card so I recommend it.

Thanks. I´ll buy it ;)
Have you overclocked your card?
Nils
*facepalm* Anyone who can read is a clear advantage.

I get 190 MHash at the stock speed of 850 MHz, and overclocking to 930 MHz gives about 205 MHash. Both of these figures are using my GUIMiner program (shameless plug).

It's summer where I live so I don't want to push it more than that for heat reasons >_>

I´ve got another Windows PC with GUIMiner. It´s very cool.
In Germany it´s summer too. 205 MH/s, that´s 1.79€ (euro) per day. Not bad.
Nils

gui miner is a very good program makes mining simple. I am getting 212 out of a 5770 right now. But I will be surprised if the card lasts another 2 month :) as I do plan to push it harder its running at 950 atm I did manage to get it to 980 but it was a little unstable so going to up the voltage a little and see if that helps

I concur. Decent for gaming as well.

What´s the power consumption?
I´m convinced of buying this card. But I can´t find information about the power consumption.
Nils

Good news. I also have ordered a 5770...

You do know that "2 slot" cards only plug in to 1 PCI slot, it just hangs over and blocks the 2nd connector.
or do you somehow have an old ITX case with only one card slot cutout in the back ??

Yes and no.
My slots are build so, that the only PCIe Slot has only 1 "Output". This Thing, were VGA and HDMI from the card shows out of the case, you know?
The 2 SlotCards have the second "Output" above the first Outpout. And there is no exit.
Nils

The 5770 is a nice card. I'm using one with the GUIMiner and getting 209 Mhash/sec (core 950 MHz and memory 350 MHz).

And your English is fine  :D Welcome to the forums  8)

*facepalm*x2
I can simple take out the mainboard and power supply out of the case.
And then, I haven´t any restrictions for cards.
I don´t need CD-Rom and HDD, too, because I use Linuxcoin
For 60€ more, I can buy a ATI Radeon HD 5850
The only thing that worries is the power consumption.
I only have a 350W power suppy. Is that enough for an Intel Pentium 4, which isn´t used when mining and an ATI Radeon HD 5850?
Nils

The 350W PSU will most likely not be enough. If not lacking watts, then lacking amperes for sure.

I´ll try. If it´s not enough, I must by a new one.
that´s life
Nils

I would be sufficient, if it´s a very good power supply with 80+ gold or something like that and if you make sure the CPU "idles" while mining.

Double-slot cards don't use two PCIE slots - they just need two slots of space in teh computer case! :) (Based on what I'm interpreting oyur issue to be... :P)

Yes, and I have only one of the slots in the computer space.
Because that, I like to take out my motherboard etc. out of the computer case.

I would prefer 5850 ATI for a little extra budget. You'll like it in a long run in terms of efficiency.

What sorts of speed are you getting out of a 5850?

Read the Thread and google a little bit may helps?

If you are looking to buy a 5850 i might be able to sell you one if you want (currently pulls in 333mhs at 830/300mhs clocks at AGGRESSION=9, temp at 60c) for about €130. Also have an unused 430w corsair psu that i could throw in for about €30, should be able to run your setup without problem (my 550w runs 2*5850, i3 processor and 2*1tb hdd's without problems, but i believe it's really at the limit and that i am lucky it actually runs it all). The card has been used for 3 weeks about 8-9hours each day, it's an Sapphire ATI Radeon HD 5850 Extreme. Depending on where you live shipping might end up costing almost as much as it would cost to get everything in new condition though.

Anyways, what you should expect to get from this card:
with bad airflow in case, wanting to use the computer for other tasks such as watching videos and card at about 60c: 320-340mhs
with bad airflow in case, not wanting to do anything else with the computer and willing to go up to about 70-75c: 355-365mhs
with good airflow in case, wanting to use the computer for other tasks such as watching videos and card at about ~55c: 330-350mhs
with good airflow in case, not wanting to use the computer for other tasks such as watching videos and card at about 70-75c: 360-400mhs

The good airflow numbers are kind of speculation since i don't have good airflow in my case and can't tell for sure), looking at the mining hardware comparison chart on the wiki is also recommended, you'll be able to get about ~3-10% higher mining speeds due to improved miners + small tricks to speed up mhs though.

Thanks for your offer. But I´m at holiday next week, and so, I don´t buy anything now.
And the airflow:
I won´t have a case. I´ll take the mainboard out of the case.
Nils

I believe you can get around ~350-380 mhash at around 70c temperature on the card which isn't really much, i think alot of people go to 80-90c without problems (yet) with the mainboard outside the case (doesn't really help airflow much to now have it in the case).

I think you should go for a 5850 and not 5770 personally, what i have seen it's only around €40-50 more than 5770 and it delivers almost twice the speed, have better resale value if you'll ever think about selling it. Shoot me a PM if you're interested to buy in the future since i probaly won't get rid of the card for some time, not really in a hurry to sell it but if a good oppertunity shows up i'll probaly get rid of it since i won't be using 2 cards in the future anyway.

You can PM me if you're unable to get those speeds (even if you end up buying from store/someone else) and i'll happily help you if i still visit the forums by then.

I changed the title.
Because I´ll buy a ATI 5850 after holiday. I´ll install is, and take the mainboard out of the case.
The only creepy thing is the power consumption.
I don´t think, that a 305W power supply is enough for this card and an intel pentium 4
Can anyone please post any advices for the power of a new power supply?
Nils

Make sure your AfterBurner.cfg file looks like this

[ATIADLHAL]
EnableUnofficialOverclocking = 1
AccessibilityCheckingPeriod = 0

After restarting afterburner, go into settings and tick "unlock gpu voltage control"

Corsair cx 430w seems to be the best choice of good quality psu with a low pricetag, the 350w might be able to run it depending on the quality, but doubt it will.

Strange: everyone seems to get around 200 Mhsish or more with their 5770, but mine (overclocked at 900) does not go beyond 178-180 Mhs with Phoenix miner, patched phatk, using this script: -k phatk DEVICE=0 AGGRESSION=6 VECTORS WORKSIZE=128 BFI_INT FASTLOOP=false.

Any advice?
(More aggression does not increase much the performance and it hogs too much my puter, while at 6 it stays fairly responsive as I need.)

BTW: with this setup temp is at 75-76 C. Should I change termal paste/ increase ventilation, or that's fine?

Perhaps that is not sufficient, you may need this lines, too:

UnofficialOverclockingEULA   = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it
UnofficialOverclockingMode   = 2

256 Worksize, downlock memory to 300.

Overclock MORRREEE!!!! IF you hate long-living cards you can get 1080MHz core
