Topic: [XMR] Monero - A secure, private, untraceable cryptocurrency - page 1304. (Read 4670643 times)

I have noticed a few people asking recently why an anonymous concurrency is even needed. I know I have seen several good articles/write-ups/posts explaining the need but cannot remember where I have seen them.

Here is one article I found:

http://www.coindesk.com/how-anonymous-is-bitcoin/

Do you know of any others?

Correct because I never mined XMR.

I was relating my experience on my system hoping it would help others. I know increasing VM on systems with low memory helps.

There has been a series of users having their bitcoins stolen when using their bitcoin wallet through tor. Tor's exit nodes can see your data. It's explained in the article.

Can anybody located in between meddle with transactions? I think not, due to lack of keys.

Luxembourg, Luxembourg ... thinking don't got to comment on that 

http://www.coindesk.com/bitcoin-tor-anonymity-can-busted-2500-month/

"Using bitcoin over the anonymity network Tor leaves users at greater risk of having their identities revealed, according to academics at the University of Luxembourg."

"Such an attack could expose the identity of a bitcoin and Tor user, and allow the attacker to meddle with the victim's transactions, they said."

No question bitmonerod does use a log of RAM (gigabytes) so that plus other applications could certainly run out in 8 GB.

A good solution is to enable virtual memory as explained in the post after yours:

I run bitmonerod/simplewallet on a windows laptop with 4gb ram - and have no problems whatsoever, even when i have not run the daemon for a week and need to resync the blockchain i have no issues. i also have browser open and irc client and all functions fine.

Apparently no one read the recommendations here:

Supported coins:
XMR/QCN/BCN/FCN/Aeon/Duck/Dash/OEC/MCN/ORION.
=========================

CPU version is here:
https://bitcointalksearch.org/topic/claymores-cryptonote-windows-cpu-miner-v40-647251

Current version: 9.1:

- Improved pool-related routines: less disconnects, more hashrate on some pools.
- Fixed issue with some old 6xxx/5xxx cards ("lowDifficultShare" error).


Previous version: 9.0:
- Improved speed by 5-15%, depends on card:
   About 810 h/s on stock 290X (Hynix memory).
   About 710 h/s on stock 290X (Elpida memory).
   About 690 h/s on stock 290  (Elpida memory).
   About 550 h/s on stock 280X (Hynix memory).
   About 440 h/s on stock 270X (Elpida memory).
   About 410 h/s on stock 270  (Elpida memory).  
- Reduced dev fee, now it is 2.5%.
- Improved "-li" option, Windows freezes even less.
- Best "-a" and "-h" values are set automatically for 290X,290,280X,270X,270,6950_2GB cards.

This is POOL version.

Catalyst 13.12 is required for best performance and compatibility. Catalyst 14.x is supported as well (usually 14.x is about 1% slower than 13.12).

Set "GPU_MAX_ALLOC_PERCENT" environment variable as "100".

For multi-GPU systems, set Virtual Memory size in Windows at least 16 GB:
"Computer Properties / Advanced System Settings / Performance / Advanced / Virtual Memory".

This miner is free-to-use, however, current developer fee is 2.5%, miner mines 39 rounds for you and 1 round for developer.
If you don't agree with dev fee - don't use this miner, or use "-nofee" option.
Attempts to cheat and remove dev fee will cause a bit slower mining speed (same as "-nofee 1") though miner will show same hashrate.

This version is for recent AMD videocards only: 7xxx and 2xx, also 6xxx and 5xxx. No nVidia support.

This version is for Windows x64 and Linux x64 only. No 32-bit support.

Linux version also requires AMD APP SDK installed. Linux version has been tested in Cent 6.5 and Ubuntu 14.04.

Do this and you will not have problems, and blocked with 2 GB of RAM!

My win7 system with 8GB froze several times when syncing if i was doing other stuff. It was ok if i left alone during sync. Once synced, I could then use normally. Problem went away when i upgrade to 16GB.

Ok I set virtual memory higher and my system is stable. I took it off the set number and checked the box that allows the system to automatically set the virtual memory size. stable now, thanks. End User Error

i checked mine also. on 8gb ram uses 4.4gb. seems same as Quicken.

akula999, i answered your question. did i not? i did not said you are FUDIng, i said, it seems we have newbie FUDing attack again. lol are you newly made account?


If  crashes started happening last 2 days, then think what you changed last 2 days and try to put it as it was before

I think the answer is no but can you be more specific what this would include?

I'm with 4 GB and for me everything is fine, but very slowly

Hmmm... first post on the thread. Could you post a screenshot/snip of task manager (if using windows) or top (in linux) to demonstrate this?

Do you know how to access Task Manager? Control Alt Delete, then select from menu. List the items by increasing memory usage, and monitor the top entries on the list while starting the daemon.

As I posted earlier, on my Windows 8 system bitmonerod uses less than 4.5 GB RAM throughout sync and when fully synced (as now).

It is down to 38% now. Not ideal, but not terrible either. Also, don't forget that the numbers can often be misleading because network hash and pool hash use different methods of measurement.

As others explained it will use RAM that is available but it doesn't need it. If other apps want the RAM or if the computer doesn't have as much RAM, less will be used. I can confirm that 2 GB hardware RAM on Linux works (a bit slowly) and 4 GB hardware RAM on Linux works great. Others have reported 4 GB on Windows working fine.

Not sure what is causing your crashing but it isn't lack of RAM.

It's called Virtual Memory in Windows and appears under advanced system settings.

I'm sorry you feel my post if FUD. Hopefully not all questions in your minds perception is equal to FUD. Maybe you're having a bad day. But, if feel i'm trying to spread FUD, then I feel sorry for you. Unlike most people here, i'm not in the tech industry. I'm just having an issue with my one PC which has bitmonerod running on it (nothing else, windows 7 w/ 8gb ram).

@akula999

Yes, from what i read here what people posted in past, that more RAM you have more it gets used. Least i saw someone said, run it on 3gb RAM.


It seems we have newbie accounts FUD attack again

No, daemon uses same RAM as it did back in May to me. And devs spend quite of some money to support what they do, not to mention they do it for free.
