Bitcoin / Mining / Re: Does video memory matter?

on: June 02, 2011, 02:14:37 AM

Are you talking about the 6950? If it is, I would get the 2GB (reference) so you can unlock shaders. If not, and the card is purely for mining (e.g. no gaming) I would save the cash and get the 1GB. More details will help.

Did you guys have to do anything special? I can't get my 6950 and my 5970 to play nice together. BSODs and other issues. Who's running linux?

Quote from: RyNinDaCleM on May 30, 2011, 01:12:50 AM I didn't know Mushkin made PSUs! Is your CPU OCed? Do you have PCI-e in the BIOS set to 100MHz? GPU Temps? MSI AB should OC multiple series GPUs. Just make sure the synchronize GPUs box is NOT checked, and you set them individually. Change to the GPU you want to adjust through the settings. On that chipset, you prolly have what... a 4x slot for your second card? And, your first slot probably drops down to 8x. Doing this kind of work, you are probably saturating these slots. Additional note: Install each individual driver for each card. Thanks for the synchronize tip. CPU is not OCed, temps are 72, PCIe is at 100Mhz. Actually mining is not memory intensive. That's why people here can use 1x extenders without a problem. Quote from: TheShoura on May 30, 2011, 01:30:05 AM I found that my 5970 would not run with any of my 6870's installed. However, a 5970+5870+5870 work just fine Just my two cents, but seems mixing isn't good. That's what I was afraid of... I'm downloading LinuxCoin right now. See if it runs in there.

Bitcoin / Mining / 5970 and 6950 crashing, slow speeds. Can't mix series?

on: May 30, 2011, 12:38:39 AM

So I got a 5970 to put in my mining rig which already has a 6950 in it. However I can't get all three GPU's to all mine. Either one slows down, crashes, or BSOD. When the 6950 is primary, none of the 5970 cores show up as CL devices. When the 5970 is primary, it BSODs right after the desktop loads. I've tried driver sweeper and reinstalled everything, now it BSODs when I have both cards in. One interesting note, when I have the 6950 as primary, under Catalyst, it says the second core of the 5970 is disabled. Anybody else having these issues or know how to fix it? I would really appreciate it. 2 monitors, one on each card 6950 unlocked 5970 800 watt Mushkin psu Catalyst 11.5, SDK 2.4, MSI Afterburner Win7 x64 Other stuff Q9300, Abit IP 35 Pro, 4GB ram Another side question, can Afterburner support multiple GPUs of different series at the same time?

I'll take the other two.

They seem to be in the $700's. for $700 you can find OC-ed 6990. 5970 was under $550 for months and nobody wanted it :/ :/ missed out on that lol. Though the 6990's are on back order. Newegg's sold out and Amazon says 1-2 months wait. By then who knows what the mining scene will look like by then...

Yeah, all those are a bit outdated. Thanks for the help guys. I guess I jumped on the boat too late. Everybody here is talking about buying now rather than mining.

This is making me not trust the wiki and makes buying hardware trickier. majority of people don't overclock (or they doing whatever ccc let them - which is usually 5-10%) default 6950 have 900/1250 and 1408 shaders now, you adding 10% in shaders, 15% in gpu clock and you wonder why your hashrate is 410 instead 360? That's what I thought initially but looking at the wiki there are people running unlocked shaders around 325 and one 295. There's even one guy is at 970 core pulling 360.

That is true. Though this makes picking new hardware a pain.

Bitcoin / Mining / Unusually High Hashing rates?

on: May 26, 2011, 04:46:25 PM

Hi I just got started into mining for Bitcoins a few days ago at btcguild. I've been tweaking my hardware and trying out different miners on my 6950 2GB. Now according to the hardware wiki (https://en.bitcoin.it/wiki/Mining_hardware_comparison) my 6950 should get between 295-360 Mhash/s. I have my 6950 at 960/700 @1.2V with unlocked shaders. I get about 405-410 Mhash/s. Is this weird? The other 6950's on the wiki are clocked higher than mine and get lower hash rate. I've tried poclbm.exe -w 64 -v phoenix with -q 5 -k poclbm VECTORS BFI_INT FASTLOOP=false AGGRESSION=13 DEVICE=0 WORKSIZE=64 They both give about the same results. I'm thinking about expanding my mining operations and getting another 6950 and maybe 2 5830's. Do you guys think that's a good idea? Thanks, awesome forum btw!
