Anyone know how to help speed up transactions.

My wallet is upto date and has synced (although that took some time)

I've transfered some coins about 2 hours ago and not 1 confirmation yet.

I was looking to start mining it to help speed things up but as it's POW is that still possible?

Do you have to do anything with your client to allow it to help process transactions or does it do it automatically when open?

I've just bought a 3GB Gigabyte Radeon HD 7950 Windforce 3X and am loving it.
I can over clock it to 1150MHZ easy and that puts out about 645KHs at I 18

Not sure about the others, when i was looking it came down to the Sapphire and the Gigabyte.
Either of those is probably good a good choice.

I too have not hear good things about the MSI ones. I think my choice was swayed by the noise. My card is nice a quite and runs at ~70C
If you get the gigabyte version the CGMiner like to keep the fans up higher than needed so i would recommend using the overclocking tool to control the fans on the card.

Good point ssateneth.

I use my machine for a lot of things, mining is one of them. Whilst i'm not at the PC i put the intensity to max.

My main reason for taking out the 6850 is I only get 200-218KHs out of it and when mining with the pair both monitors stopped displaying. I jumped to the conclusion this was related to power and after a few minutes i turned off the PC removed the card.

I'm tempted to get another 7950 but will wait till the 9 series comes out as it should either price drop the 7950 or the new ones will be worth buying.

In theory i can probably run both cards ok but i didn't think it's worth the risk.


RChevalier point about the PSU is a good one and makes me think about getting a better rated PSU as mine is only a bronze.
My old PSU will be used for a mining rig with the 5850 and the 6850 in it.

Looked at Gold and above for PSU.

Which of these would you recommend?

1000W

Hi all

Anyone know a good place to buy risers in the UK and what is a good price?

I've got an old machine and some spare cards.

Hi all

plugged in my 7950 and my 6850 and it worked. I was measuring wattage from the PSU and mining with both put it very close to the limit.
I could turn down the intensity but in the end i took out the 6850 as it's only getting 218KHs at I17 and overclocked as much as possible.

Might get a new PSU and another 7950 then setup a separate rig with some old components and the 6850 and 5850 with my current PSU.


What would people recommend for a PSU for 2 7950?
750W or 850W

I was looking an an XFX 850W PSU but wanted to know if they are any good. Looks like they are made by seasonic like Corsair ones are.

Any recommendations?

Thanks everyone. Some very mixed views on here.
According to eXtreme PSU Calculator my setup will only use 451W at full load (Assumes no overclocking)
I'm not convinced by this.

The 600W power supply will at least take the 7950 on it's own.

I'm tempted to put the 6850 in but not mine on it for now. what do people think?

I would like to get another 7950 at some point and would need a new PSU anyway, what would you all recommend for the PSU?

Thank you,

Looks like i need a new power supply then.
What would you recommend?
I may put another 7950's in later on so with that in mind i may as well get a PSU which can handle both.

What's the easiest way to monitor how much power you are drawing?

Hi there

I'm currently running a 6850 and a 5850 on a 600W Corsair PSU in:

Corsair 600W CX Builder Series 80 Plus PSU
Core i7 2600k
Corsair Vengeance 8GB (2x4GB) DDR3 1600Mhz
Gigabyte GA-Z68X-UD3-B3 Z68 Socket 1155
Arctic Cooling Freezer 7 Pro rev 2 Socket 1155
1 SSD
1 HD (7200)
3 120 MM fans
1 140 MM Fan
1 DVD RW

Will i be ok to replace my 5850 with a 7950 and keep using the same PSU or am i going to have issues?

Also what happens if you draw too much power from your PSU does it shut down or blow?

Anyone know how to access your stats for this pool via the API. The link the pool provides returns a 404?

I mined on this pool yesterday for over 12 hours at 535khs and got a total of 0.3796 ftc

was something up?
i switched pools after the difficulty change as the blocks were not returning.

Good point I forgot to mention my power supply.
It's a Corsair 600W CX Builder Series 80 Plus Bronze

I'm also mining scrypt so i'm guessing the 3GB cards would be better than the 2GB ones?

Hi all

I currently have a 600W power supply running an I7 2600K, 8GB memory (2 sticks), 1 120MM case fan and a 140MM case fan with a 6850 and a 5850

I was wondering about putting in a 7950 but am thinking that my PSU will need an upgrade.

Can i put in a 7950 to replace my 6850 without changing my PSU?
Would be able to put 2 7950's in place of my current cards?

Thank you

I'm very intrested in this as well. I'm a software developer by trade but I have a firm interest in the electronics side of things. My father runs an uk electronics business with machines which can make boards. He also has an office in china for supplies and may be able to get deals on large volumns of chips.

Pm me if intrested.

Wow didn't think it would spark such a debate.
I'm gonna give water cooling a miss but did anyone have a suggestion about the fan arrangement. 

Hi all

I have 2 Gpus in my rig and I wondering about cooling. I have two case fonts at the top on blowing up out of the case and one at the top back blowing out.

Would I be better moving the back fan to the side panel and blowing air in over the cards?
Or should I just buy another fan?

installed the 2.8 drivers and it's back up and running. i'm now getting 322 out of my 5850 at I 18

Ok now I'm stuffed. Uninstalling the drivers and putting 12.8 on has messed things up completely. Installing 13.5 does not help either.

Help.

After installing 12.8 drivers i get the following from GPU-Z
---------------------------
GPU-Z
---------------------------
ATI OpenCL driver bug detected, skipping OpenCL detection.
Uninstall the AMD Stream SDK / OpenCL driver to re-enable this functionality.
---------------------------
OK   
---------------------------

any ideas?

I have the AMD-APP-SDK-v2.5-Windows-641.exe should i instal this as well?
