parroty Posted April 25, 2007 Share Posted April 25, 2007 Hi, Just a general question. I've just completed the build of a PC: AMD2 5600+, XFX 7800GT, motherboard: ASUS M2N-E and Corsair 2 x 1GB (TWIN2X2048-6400C4). The Corsair memory (TWIN2X2048-6400C4) is rated 4-4-4-12-2T on the http://www.scan.co.uk and corsair website. The M2N-E motherboard (Nvida 570 Ultra MCP) has been flashed to bios rev 802. When looking in the bios (Under CPU Settings -> DRAM Settings) or in memtest+ V1.70, the CAS is: 5-5-5-18. I'm new to this, i know EPP is available on the nForce 600+ chip-sets. I've also read that to get 4-4-4-12-2T as advertised by corsair, you need to change the memory settings in the BIOS. What do i need to change in order to get the memory to register as 4-4-4-12? I had a play in terms of changing settings, but the system wouldn't boot when set to: Mem Clock Freq: auto (left default) TCL: 4 TRCD: 4 TRP: 4 TRANS: 12 1T/2T timing: 2T I even changed the memory clock frequency to: from auto to DDR2 800 and still the same problem. Both sims are located in the yellow slots (dual channel 1). The system booted to logo screen and hung, in some instances it would go into a reboot cycle. Cleared BIOS, booted ok under default: 5-5-5-18-2T I popped the simms out and swapped them over and reseated them, the system booted under: DDR2 800 4-4-4-12-2T Completed the first 4 tests on memtest+ V1.70 and failed 95% in on test #5 and fails throughout test #6. Yet if i reset the mem settings to auto (5-5-5-18), test #5 completes successfully. I did notice one of the simms was a hot and the other cool. There are lots of additional memory config options below the high level settings. Is there something that needs to be changed? The ASUS manual is available here (Under Section 4.4.4) http://dlsvr03.asus.com/pub/ASUS/mb/socketAM2/M2N-E/e2630_m2n-e_manual.pdf Memory specs: Spec 1: http://www.corsair.com/corsair/products/specs/TWIN2X2048-6400C4.pdf Spec 2: Supported for my motherboard (see Performance Reports available for this motherboard): http://tools.corsairmemory.com/configurator/product_results.aspx?id=5233 Are there other settings that need to be made (V2.1 voltage??) I've found a setting in the motherboard manual.. DDR2 Voltage Control. Options: [auto] [1.80V] [1.85V] [1.90V] ~ [1.95V] I can't find 2.1V, spec 1 says 2.1V however, spec 2 says 1.90V. Any help would be great, just in case there is a fault with the SIMMs. Link to comment Share on other sites More sharing options...
