I'm getting the same issues as others where a few cards in each 400 series rigs have 300 clocks and don't hash.

UPDATE v1063:
- updated optiminer v1.6.1
- added separate sgminer-gm-nh (nicehash version) 5.5.5-4
Note. To use new optiminer, you need to reload/reboot your rig to start mining on newer version !

I will do this right now !
For sure it will be faster and more updates after i will implement one feature called "service fee"
That way i could spend much more (even full time) on simplemining - so its a good idea to make it soon (first as preferable donation - not to force ans scare people off )

Also guys if you have issues, pleae check if you have the same problem with claymore-eth miner.
This miner is STABLE while ZEC miners (optiminer especially, uis causeing some issues)
So if on eth miner its working well then at least we know something
Also we caould try updating to even newer kernel to see if meaby it will be fixed.

VM_Context1_Protection_Fault_Addr - this happens mostly when there is too much undervolting on custom bios.
Sometimes too much gpu OC.
So for RX470/480 its best to test first on claymore ETH miner at clocks :
core: propably max but you can lower to 4-6 dpm state
memory: first is best to check if on 1800 mhz its working well.
Some of my undervolted rigs and tunned timigs have problems at >1933 MHz (my rigs below on image)
Also XEC is unprofitable right now as calculator says ?
Anywa i find ZEC mining more problematic which ETH/ETC works very nice.

Hi Tytanick,

I know you are busy as a bee on SRR project but do you have timeline to update the miners below:

sgminer-gm v5.5.5-4
optiminer v1.6.1

I need to complete a few projects for my clients within 24 hours, and need to use sgminer-gm v 5.5.5-4 urgently.

Thanks

Solid Mining for over year with RX480s, R9-Nanos, MSI-390s:

1. 66 x Sapphire 480 8GB (Ref) with "480lowenergyOK.rom" from Heliox.
2. 32GB Sandisk USB3 thumbdrives for 6 newer rigs
3. Kingston 120GB/SATA-SSD (previously with Windows but now all smOS)
4. None - did not messed with defaults on ASrock H81 Pro-BTC mobo, except for auto-power-on-bootup. Also, powered molex and powered PCI-USB3 risers for ASrock H81 Pro BTC motherboards.

I don't get IO errors.  I get VM_Context1_Protection_Fault_Addr   .  I am guessing this may be a contributing factor.  The remaining GPU would hash at very good speed.  I don't think this is an issue with USB 2.0 or 3.0 as the rigs either work or they dont abeit maybe choking at some point but they should hash.  I have a RX image rigs few that works with USB 2.0 no issues for ARmor and Red 480.  I've tested on the problematic rigs just now with USB 3.0 as well as SAN disk 120GB SSD so it's not a drive performance issue.  Even test this on Stock ROM rigs.  Seems to play best on R Image.  For RX seems to be more stable on the MSI 480 Armor.  MSI 480 Red is hit or miss.  So far every 470 MSI rigs I've tried would have all the GPU show up but at least 1 or 2 GPU showing 300 and not hashing.  So it sees them, it's just not able to do anything with them which is frustrating.  I've test this on over 20 different RX rigs now, only got 3 rigs to work perfectly but I'm a big MSI shop.  


This is what we need to know.


1) What GPU have been tested to work -  Brand and model
2) What Flash Drive type and speed have been confirmed to work no issues
3) What SSD drive and brand have been confirmed to work no issues
4) Any Caveats or gotchas you've guess seen such as make sure MB PCI is set to Gen 1, Gen 2, etc

What type of 480 and 470 do you have? I can't seem to make simplemining os to detect all of my MSI 480 or 470 4 GB GPUs. Some rigs it will detect 4 out of 7 GPUs (3 would have 300 core or 300 memclock), another rig it will detect all. I am using 16 or 32 GB USB 3.0. Wondering if it is because of low quality MSI GPUs? It does work flawlessly with R9 Furys.

Yeah at times eBay has good deals. I am moving and shifting setup just a bit. Happy so,far with this method.

very good buy this Phil.

m2 storage will be really fast and Linux will love that.

USBs are designed for data/files portability -- so -- its best to go for reliable permanent storage at wire speed.

I got screwed on some sandisk usb 3.0 sticks they did not work well.

I saw the lot of 10 m2 pcie ssds  from kingston 48 bucks  only $4.80 a pcie  they are gold so far

The cheap USBs don't work, many errors mostly IO Linux errors.

Need USB3 type thumbdrives for best results.

6 of my newer rigs Z170s mobo, no SSDs or m2, uses USB3 thumbdrives and runs well.

The other existing 24 rigs - do have SSDs already, I just replaced the Windows with smOS image.

If you have m2 storage, I think its best to use them because cost of small and cheap m2 storage still does its job at wire speed, versus a USB which will need USB3 for speed and decent capacity 16/32GB, which probably is around the price of the m2 storage and USBs if not from reputable brands, have many horror stories usually manufactured in small dark alleys.

Do you use USB sticks?

After many tries I decided  to use pcie images not USB sticks

It appears the issues is mainly with the RX image.  The R image are very stable.  I have tried on over 30 different rigs.  All Furies R image rigs are stable, only 3 out of 15 RX Rigs can detect all GPUs and running without issues.  My RX are mostly MSI RX470 / 480 on stock and MOD bios.  I've upgraded the Beta release and same issue.  If you we see it showing 300 speed, that means that GPU is failing or having issues.  No issues with Windows. Hopefully this will get fixed soon.

Komodo  every day counts (still easy to get those)

Guys if you have overclocking problem please tell me if applying BETA KERNEL if fixing it ?
It should

About optiminer and sgminer, yes i will implement next versions.
Give me little time

yeah  I made about 6 clones so far  and put them in  the biostar  z170s   or into this case  for my no m.2 pcie boards

Phil  I saw you purchased   this set of 10 small m.2 pcie ssds

Do you use them in your four card biostar z170 builds?

http://www.ebay.com/itm/112143250197?

I get it also







I added a mobo and spread cards around working better now.  The room is 93f I am going to open door to cool room down

upon bootup, I see this 300mhz issues once in a while.... but will go away after a while when hashing starts.

I am unsure if this is a kernel issue but its a small issue non-impact to overall mining.

Unless if the rig stays stuck on 300mhz, then GPU or riser could be the culprit (or underpowered PSU). If you are using ASrock mobo with on-mobo molex power, be sure to power that too. And use powered risers especially if your rig has multiple GPUs.

Hi Tytanick,

Can you upgrade sgminer-gm v5.5.5 to latest sgminer-gm v5.5.5-4

The latest one fixed cryptonight issues on Nicehash pool.

Thanks
