bleach Posted September 22, 2006 Posted September 22, 2006 Well i've tried alot of different things and basically my problem is my opteron 144 cab1e wont pass prime. It passed All 3dmarks, AM3, pi 32M, etc etc. The settings im trying are : - 334 x 9 (3 x HTT) vcore 1.52V. Ram at 166 (280mhz) 3-4-4-8 memtest error free. This setting passes everything except prime. - 311 x 9 (3 x HTT) passes prime. ram 180 (5/6?) - 334 x 4 (3 X HTT) fails prime/ ram 166 - 334 x 4 (1 X HTT) passes prime./ ram 166 -334 x 4 (2.5 X HTT) fails. My settings are as follows: ========== [b]Genie BIOS Settings:[/b] [color=red] FSB Bus Frequency............................. - 334 LDT/FSB Frequency Ratio....................... - 3x CPU/FSB Frequency Ratio....................... - 9x PCI eXpress Frequency......................... - 100Mhz CPU VID StartUp Value......................... - 1.500v CPU VID Control............................... - 1.40 CPU VID Special Control....................... - +109% LDT Voltage Control........................... - 1.30v Chip Set Voltage Control...................... - 1.59v DRAM Voltage Control.......................... - 2.84v[/color] [b]DRAM Configuration Settings:[/b] [color=red] DRAM Frequency Set............................ - 166=RAM/FSB:3/4 Command Per Clock (CPC)....................... - Enable CAS Latency Control (Tcl)..................... - 3 RAS# to CAS# delay (Trcd)..................... - 4 Min RAS# active time (Tras)................... - 8 Row precharge time (Trp)...................... - 4 Row Cycle time (Trc).......................... - 12 Bus Clocks Row refresh cyc time (Trfc)................... - 16 Bus Clocks Row to Row delay (Trrd)....................... - 02 Bus Clocks Write recovery time (Twr)..................... - 03 Bus Clocks Write to Read delay (Twtr).................... - 02 Bus Clocks Read to Write delay (Trwt).................... - 04 Bus Clocks Refresh Period (Tref)......................... - 3120 Cycles DRAM Bank Interleave.......................... - Enabled DQS Skew Control.............................. - Auto DQS Skew Value................................ - 0 DRAM Drive Strength........................... - Auto DRAM Data Drive Strength...................... - Auto Max Async Latency............................. - 10 DRAM Response Time............................ - Normal Read Preamble Time............................ - 7 IdleCycle Limit............................... - 256 Cycles Dynamic Counter............................... - Disable R/W Queue Bypass.............................. - 16 x Bypass Max.................................... - 04 x 32 Byte Granularity........................... - Disable(4 Bursts) [/color] Quote Share this post Link to post Share on other sites More sharing options...
Gothic Case Posted September 22, 2006 Posted September 22, 2006 It seems like a problem with your either your FSB/HTT or your CPU speed... As you said, it failed priming @ 334x3 HTT speed... make sure you can do this before atempting the so lovely 3GHz... Quote Share this post Link to post Share on other sites More sharing options...
dr_bowtie Posted September 22, 2006 Posted September 22, 2006 try bumping the LDT and chipset voltage a bit more... seems funny it will pass with a 1x multi and nothing else..? Quote Share this post Link to post Share on other sites More sharing options...
Praz Posted September 22, 2006 Posted September 22, 2006 One of your problems is DDS/DDDS set to Auto. The Expert is good at picking these values at lower HTT but at 334 you are going to have find the correct values. Quote Share this post Link to post Share on other sites More sharing options...
bleach Posted September 22, 2006 Posted September 22, 2006 Well I didnt bother with DDS/DDDS. What I did do was dump 1.616 volts on the core and now it passes anything, max load temp 47 degrees. Quote Share this post Link to post Share on other sites More sharing options...
Praz Posted September 23, 2006 Posted September 23, 2006 The only reason they're working on auto is because the rest of the secondary timings are set so loose. If you ever get to the point that you want to optimize your system and get the most out of it at the lowest possible voltages you will be manually setting those values. But I guess all that matters is the big 3.0. Not how you get there. Quote Share this post Link to post Share on other sites More sharing options...
bleach Posted September 23, 2006 Posted September 23, 2006 yeah well. TBH, I have no idea where to start with the DDS and DDDS. I tested a few settings and windows wouldnt boot. I will eventually tweak it but im already scoring big in all benches. Dont forget the ram is running at 270mhz so tightening anything might not be possible.

Praz Posted September 23, 2006 Posted September 23, 2006 Dont forget the ram is running at 270mhz so tightening anything might not be possible. My mistake. CPU-Z sure looks like it says 250.5 for the memory in the screenshot. I guess I can't see it clearly. Quote Share this post Link to post Share on other sites More sharing options...
bleach Posted September 23, 2006 Posted September 23, 2006 ahh too right you are. so thats what disabling odd dividers did. I'll prime again tonight at 270mhz ram. Quote Share this post Link to post Share on other sites More sharing options...
Praz Posted September 23, 2006 Posted September 23, 2006 Depending on processor multiplier and memory divider, Odd Divisor Correct will lower memory speed to the equivalent of the next lower divider. Quote Share this post Link to post Share on other sites More sharing options...
