1  Other / CPU/GPU Bitcoin mining hardware / Slow down of GPUs (85% usage) on: June 24, 2011, 08:58:24 PM
Hi there,

For today my problem is:

When running two GPUs they cant be set with argument -f0, because GPU usage drops to around 80/93%. Im wondering, if there is something wrong with my rig or its common problem.

XP sp3
C2D E7400 @2.8GHz
Gigabyte P31-ES3G
CC 11.4
SDK 2.1 (same problem with 2.4)
poclbm (poclbm with phatk,phoenix got this problem even bigger)
GPU1: 5850 Xtreme
 -f30 -r5
currently avg 380MHash while both cards running, solo 387MHash (on same '-f')
GPU2: 5870 Vapor
 -f2 -r5
currently avg 419MHash while both cards running, solo 435MHash (on same '-f')
2  Bitcoin / Mining software (miners) / New POCLBM compiling request on: June 23, 2011, 10:44:25 PM
As I found out there is new poclbm version (17 June).

Whats new:

Supporting backup server (YaY). Thing is, that this version is not compiled. Can someone write little tutorial how-to ??

New poclbm is available at:

Just making big advertisement of it. Grin
3  Bitcoin / Mining support / Not fully working cards (only 70%) on: June 19, 2011, 09:48:31 PM
Have new problem.

Added second card to my rig. Now have 5850 on PCI-e 16 and 5870 on PCI-e 1. Cant change places of cards, cuz getting lower hashrate if 5870 is in higher slot... Even now I have to use higher -f values (-f40 for main card and -f2 for second one), cuz otherwise main card is working at around 60% and other around 90-95%. Any idea how to solve it?

4  Bitcoin / Mining support / Problems with router settings on: June 16, 2011, 07:52:04 AM
My router recognises pool messages as some kind of attack and blocks incoming data as blacklist defense. I turned off whole blacklist thing, but suddenly other messages came, like "policy migration" or "not sufficient data". After all I think its better to change rules for blacklist than to handle new problems all over the time.

Settings are:

                      IDS Enabled: true
                     Use Blacklist: false
             Use Victim Protection: true
         Dos Attack Block Duration: 1800
        Scan Attack Block Duration: 86400
  Victim Protection Block Duration: 600
    Max TCP Open Handshaking Count: 100
                    Max PING Count: 15
                    Max ICMP Count: 100

Also I cant disable IDS (no such option via telnet or www GUI).

Forgot main idea of this topic... Please tell me what rules should I change so pools wont be blacklisted...

Also what is strange - when ip is blacklisted I cannot see website or get share data. But now it blocks in some way, that GPU are getting connection problems one by one (ex. now at 2GPU rig only first one is hashing, other has connection problems (passed out 30minutes after PC and router restart...)
5  Other / CPU/GPU Bitcoin mining hardware / Problem with 2xcard rig on: June 13, 2011, 04:14:10 PM
Today arrived second card for my rig. After checking, if new card is fine I cut PCI-Ex 1 slot, installed there card and checked, if slot is working. Everything was fine till then. Next step was to instal both cards. PC booted, windows recognised both cards, but it "cant run the device", dunno why. Tried rebooting, but still nothing.

Both cards are connected to monitor, both are 5850 by Sapphire (1x Vapor, 1x Xtreme). Any idea whats wrong?
6  Bitcoin / Mining / Multiple cards with PCI-E-x1 - newbie question on: May 31, 2011, 08:19:57 PM
Befor I start to destroy my old MOBO I wanted to ask - will 2 cards work on MOBO, which chipset (P31) doesnt support crossfire/SLI. I'm not going to crossfire my radeons, but just wondering, if it will work.

PS. Any advices how to safely cut back of slot?
7  Bitcoin / Mining / SDK NOT important on: May 26, 2011, 10:10:21 PM

I've made few researches. (damn, sorry for misspellings but little drunk...) People here on forum are telling, that one some SDK U'll get better results, on others worse. Its TRUE. BUT, power, consuming by card will also increase, same temperature.

Been doing 380Mhash/s on 2.2 SDK or 2.4 SDK. Changed to 2.1 SDK and 395 MHash/s. But also was using 15 W more, as well as 5C more with 100% fan (74C @ 75%fan vs 79C @ 100%)(same clocks). After calculating additional profit from hashes - additional cost of power = the same. The adventage is lower temps on card, which means it will last longer.

Could some1 exacly explain to me what should I get, in which way insert to pendrive and how to setup BIOS? Once I tried it, but after 4 -5 failed tries I gave up.
9  Bitcoin / Mining / which CPU miner for C2D? on: May 17, 2011, 09:34:07 PM
As topic says, looking for good CPU miner (when u dont pay bills, u want to set everything whats possible).

With the one added to Guiminer got only 1.7 Mhash at C2D E7400 @3.5GHz, which comparing to wiki comparison is little poor.
