Title: 4GB RAM not enough to run CGMiner on R9 290x, .. Why?? Post by: msbtc on January 13, 2014, 01:57:12 PM I can't run CGMiner or Guiminer (my first choice) on my brand new mining rig. 4GB Ram appears to be the culprit-
Windows boots up fine runs fine, install CGMiner or Guiminer, check- but then "connection problems" is the error it throws when I fire up the miner. Internet works fine, FF works fine, downloading fine.. so it isn't a "connection problem" obviously. What works.. I replace the 4GB ram stick (yes in the right mb slot) with an 8gb one and presto! mining! All parts are brand new, and I even tried replacing the 4gb with a higher quality one, same thing happens! The ram is nearly identical as far as I can tell but only the 8gb stick works? Can someone please tell me why? The 8gb stick is borrowed from another system and needs to go back to it. I really just wanted the 4gb stick to work. specs: Windows 7 64 ASUS M5A99FX PRO R2.0 AMD Sempron X2 190 4X Sapphire R9 290x 2x Corsair 650 gold rated psu with adapter and risers. RAM not working: CORSAIR 4GB DDR3 1600MHz CL9 Vengeance XMP Memory PC12800, CL9-9-9-24 Ram Working: Corsair 8GB DDR3 1600MHz CL9 Black Vengeance Memory 2x8GB, PC3-12800, CL9-9-9-24, XMP 1.3 any help please...

I had a similar problem - when using some good but older athlon (with ddr2 memory) a while back. When mining scrypt with 7950 it would give me bad numbers, hw errors or would not start at all, depending on config. I moved it to ivy celeron with 2gb of ddr3 and it worked fine. I have a single r9 270x on that celeron now running it's max speed. my 2 cents. Also make a comparison with mining sha256 see how it plays out with either stick.

Because I'm pretty sure it won't, if ram has anything to do with it.
It should say something like this if your TC settings are not right, either because of not enough memory, or you aren't using the right gpu flags http://i879.photobucket.com/albums/ab357/pontiacg5_2010/LL_zps70c8a0b4.jpg Title: Re: 4GB RAM not enough to run CGMiner on R9 290x, ..

Post by: msbtc on January 13, 2014, 02:17:41 PM It only says "connection problems" in guiminer, that''s the error. cgminer just hangs forever- although both cgminer and guiminer work with the 8gb stick.
thread concurrency, thanks I'll try that. old architecture processor, I'm not sure. If I had a way to test a newer one... thanks for any info- |
