Alternate cryptocurrencies / Mining (Altcoins) / Re: Custom RAM Timings for GPU's with GDDR5 - DOWNLOAD LINKS - UPDATED

on: April 15, 2017, 09:06:51 PM

Hi I have tuned some RX480 with 8GB Samsung memory. Finally i used this custom strap: Code: 777000000000000022CC1C00106A5D4DD0571016B90D060C0060070014051420FA8900A0030000001011333DC0303A17 I use it on three different cards. - MSI Armor - Asus Strixx OC - Powerful Color Red Devil On both, asus and msi i get already memory errors above 2000MHz, a few, about 1 of 15 run without memerrors at 2100 over 24h. On the red devil all runs 2100MHz without any memory errors over 24h. So on the red devil 30,5MH/s, other only 29MH/s. Are there different Samsung memory chips? Original straps here: Asus Strixx RX480 8GB OC Code: 1500 555000000000000022CC1C00AD595B41C0570E14B00B450A0068C70003011420FA8900A003000000170E2B34A42A3116 1625 555000000000000022CC1C00CE616C47D0570F15B48C250B006AE7000B031420FA8900A003000000190F2F39B22D3517 1750 777000000000000022CC1C00106A6D4DD0571016B90D060C006AE70014051420FA8900A0030000001B11333DC0303A17 2000 777000000000000022CC1C0031F67E57F05711183FCFB60D006C070124081420FA8900A0030000001E123A46DB354019 MSI Armor RX480 8GB Code: 1500 555000000000000022CC1C00AD595B41C0570E15B00B450A0068C70003011420FA8900A003000000170E2B34A42A3116 1625 555000000000000022CC1C00CE616C47D0570F16B48C250B006AE7000B031420FA8900A003000000190F2F39B22D3517 1750 777000000000000022CC1C00106A6D4DD0571017B90D060C006AE70014051420FA8900A0030000001B11333DC0303A17 2000 777000000000000022CC1C0031F67E57F05711193FCFB60D006C070124081420FA8900A0030000001E123A46DB354019 Powerful Color Red Devil Code: 1500 555000000000000022CC1C00AD595B41C0570E14B00B450A0068C70003011420FA8900A003000000170E2B34A42A3116 1625 555000000000000022CC1C00CE616C47D0570F15B48C250B006AE7000B031420FA8900A003000000190F2F39B22D3517 1750 777000000000000022CC1C00106A6D4DD0571016B90D060C006AE70014051420FA8900A0030000001B11333DC0303A17 2000 777000000000000022CC1C0031F67E57F05711183FCFB60D006C070124081420FA8900A0030000001E123A46DB354019 I have marked the difference in 2000 straps.

I see often some connection problems, is your server good up and running? I also have one rich (similar to others in software and hardware) bur not showing the temperatures of cpu and cpu, no fan speed, only hasrate and graph. Sometimes i have deep drops in hashrate, but can't find confirmation in the log's. How to troubleshoot the temperature/clock/fan issue?

Quote from: c1oud on April 14, 2017, 11:02:34 PM Guys, this rom works with Asus Strix RX 480 O 8GB? tryied to play with bios my self but do have interesting results under ethos - few cards at 28-29 and other at 18-19 all cards are same with samsung chips (Ellesmere). Maybe any1 can comment on that or share a rom wiht undervolt included (not sure how to undervolt rx480 under ethos)? Thx in advance for you idea/roms/solutions My Custom Asus Strixx RX480 8GB Samsung. http://wikisend.com/download/348864/Strix_Kuna_v9.1.rom I'm running 1150/2060, of course You can go up 2100 and more. Set memory voltage to 950 with some tools. GPU voltage is automatic from P5 level.

Actually, which memory strap are you using as best for samsung 8GB? Do You care about memory errors and clock down until the errors are about zero?

Asus STRIX ROG 8GB OC I have several cards, some have 256k bios, some 512k. Posting both. https://ufile.io/51702 https://ufile.io/c50db1

Alternate cryptocurrencies / Mining (Altcoins) / How to you find the undervoltage limit RX480

on: April 04, 2017, 08:47:00 PM

How are You doing it? Is there a method? For example one card at time, down by 10mV pro minute, find the point it crashes, up 50mV, done?

Quote from: JustFormat on April 03, 2017, 01:37:58 AM Sadly no. I tried with more power (core and power limit) and tried mem 2250. Can't get past 28 on all 4 cards Which memstripe? Try upping the clock slow from 2000 up in 25 steps. Watch for memorry errors with hwinfo.

Quote from: Walrusbonzo on April 03, 2017, 07:30:04 AM Quote from: bitkuna on April 03, 2017, 04:56:34 AM Tired of setting each card voltage? Offset not availible in Your bios? I lowered the voltage by setting the top gpu voltage to P4 or P5 (65286 or 65285) in polaris. So You get automatic a low energy high hash rate without too many try and error per card. Polaris GPU table: 1000 65284 1050 65285 1075 65286 1100 65286 1125 65286 Set memory voltage in WattTool to 900 or lower as the low limit for VDDC. Gives 1060W from the wall for a 7x RX480 rig @204MH/s. More MH by tuning each card's clock. You should be able to do better than that. I've got a 7 RX480 rig pulling 207mh/s, each card at 1125/2050, pulling just 940w from the wall. I haven't even tried lowering the memory voltage. Good, which memory? Paste Your mem strap pls. and what voltages are You running (VDDC)? Thx

Actually, what You see in WattTool as memory voltage is MINIMAL GPU CORE VOLTAGE FOR THIS MEM FREQ. So if You set: GPU 1120 @ 850mV MEM 2050@1000 mV You will get a GPU voltage of 1000mV.

Quote from: JustFormat on March 29, 2017, 08:15:12 PM I get 27-28 also on 4 card. I just did the strap MOD 1750 -> 2000. Core 1266 and mem 2000. It does not go faster at mem 2250. If anyone else has info to squeeze more juice out it would be appreciated. With the 1750 strap, 1150gpu and 2100mem you should get stable>29MH.

Hi. Great tool, where does it take info from? miner log file? I am getting NO MINING INFO FOUND, If the miner just start wait ultil it is initialized I moved my logfiles by miner config outside the miner directory, because i'm syncing the miner directory to dropbox for easy sync and change, but don;t want my logfile sync'ed (traffic). Can monitorig look in some tther directory for the logfile??? Thx Will donate
