sazerty Posted June 23, 2007 Posted June 23, 2007 Hi all, I need your help to overclok my new Opteron 185 because i can't get it to run stable (OCCT Auto 30min) at more than 2760 (230x12) @ 1.360V (CPUZ 1.40) you can see my Genie BIOS Settings below: FSB Bus Frequency = 230 MHz LDT/FSB Frequency Ration = X 4.0 LDT Bus Transfer Width = 16 16 CPU/FSB Frequency Ratio = X 12.0 PCI eXpress Frequency = 101Mhz K8 Cool'n'Quiet Support = Disable CPU VID StartUp Value = StartUp CPU Core Voltage = 1.38V LDT Bus Voltage = 1.41V Chip Set Voltage = 1.51V DRAM 2.5V Voltage = 2.87V CPU VID Control = 1.350V CPU VID Special Control = Above VID * 104% LDT Voltage Control = 1.40 V Chip Set Voltage Contole = 1.50 V DRAM Voltage Control = 2.80 V DRAM+ .03V If it's not 3.2V = Enable DRAM Configuration Settings: DRAM Frequency Set.............................. - 200=RAM/FSB:01/01 Command Per Clock (CPC)....................... - Enabled CAS Latency Control (Tcl)....................... - 3.0 RAS# to CAS# delay (Trcd)..................... - 03 Bus Clocks Min RAS# active time (Tras).................... - 08 Bus Clocks Row precharge time (Trp)........................ - 03 Bus Clocks Row Cycle time (Trc).............................. - 07 Bus Clocks Row refresh cyc time (Trfc)..................... - 14 Bus Clocks Row to Row delay (Trrd)......................... - 03 Bus Clocks Write recovery time (Twr)....................... - 03 Bus Clocks Write to Read delay (Twtr)...................... - 02 Bus Clocks Read to Write delay (Trwt)...................... - 03 Bus Clocks Refresh Period (Tref).............................. - 4708 Cycles Odd Divisor Correct................................ - Disable DRAM Bank Interleave............................. - Enabled DQS Skew Control.................................. - Increase Skew DQS Skew Value.................................... - 255 DRAM Drive Strength.............................. - Auto DRAM Data Drive Strength....................... - Auto Max Async Latency................................ - Auto DRAM Response Time.............................. - Fast Read Preamble Time................................ - Auto IdleCycle Limit....................................... - 256 Cycles Dynamic Counter.................................... - Enable R/W Queue Bypass................................. - 16 x Bypass Max........................................... - 07 x 32 Byte Granularity................................. - Disable(4 Bursts) I'am just upgrade the CPU from AMD64 X2 4200+, that run fine 2600 (260x10) @ 1.5V (idle:34°C / Full:46°C) I've no make change on the Ram settings I know that my Ram can run fine until 273Mhz @ 2.80V with this timmings. I have see a lot of opteron 185 get 3Ghz with the same step on air. Why i can't get more with my 185 ? Where i make mistakes in the bios settings ? My aim is to get 3Ghz(250x12) stable on air.

schoolslave Posted June 23, 2007 Posted June 23, 2007 What is your CPU's stepping? Share this post Link to post Share on other sites More sharing options...
red930 Posted June 23, 2007 Posted June 23, 2007 What is your CPU's stepping? It's in his sig, CCBBE 0615EPMW. To me, increasing your voltage would be the most obvious thing to do. Since I don't know your temps, though, I don't know how feasible that is. Share this post Link to post Share on other sites More sharing options...

Since I don't know your temps, though, I don't know how feasible that is. you want to know the temps at stock (2600MHz / 200 x 13) or at this current overclock 2760MHz (230x12) ? is the settings of the memory can limite the CPU overclocking ?

bldegle2 Posted June 23, 2007 Posted June 23, 2007 put your ram on a divider to see what is with the cpu.....you have a good stepping should get more than what to got top end.... and, yes, ram settings are HUGE when it comes to DFI's.... laterz Share this post Link to post Share on other sites More sharing options...
Kingfisher Posted June 24, 2007 Posted June 24, 2007 I may need to adjust my sig to have a disclaimer.... When you change a socket 939 cpu you also are changing the memory controller as it is "built onto" the cpu itself. You will have to re-test your RAM timings in Genie BIOS to check stability.

red930 Posted June 24, 2007 Posted June 24, 2007 I second what King said. And yes, I would like to know temps at 2760. Although RAM may be the total cause, maybe more voltage is needed. It is recommended to keep an AMD processor's voltage anywhere below 1.55v, temps permitting. I notice you have a set of 5B-F chips. I also have a set, and mine were a bit tricky to find the right settings for. Good luck. Share this post Link to post Share on other sites More sharing options...

When you change a socket 939 cpu you also are changing the memory controller as it is "built onto" the cpu itself. You will have to re-test your RAM timings in Genie BIOS to check stability. ok i've tested again my Ram and it work on the opteron 185 exactly like it run on the X2 So the maximum is 273Mhz @ 2.80V with the same settings (first post) It's in his sig, CCBBE 0615EPMW. To me, increasing your voltage would be the most obvious thing to do. Since I don't know your temps, though, I don't know how feasible that is. ok, so i have made all the test with a Vcore of 1.44V (1.425 +104%) put your ram on a divider to see what is with the cpu.....you have a good stepping should get more than what to got top end.... and, yes, ram settings are HUGE when it comes to DFI's.... laterz I make some test with x13 coef and system was stable until 2775MHz (213MHz x 13). the ram is not the trouble cause like i said before it run fine with this setting until 273MHz. where i've make an error on the bios settings that cause this limit of the overclocking ? On this graph you can see the limit i have obtain with the opy and in the colored cell was in the tab is the test i've made (OCCT 30min) : . . i'am so far of my aim of 3GHz :sad: I second what King said. And yes, I would like to know temps at 2760. Although RAM may be the total cause, maybe more voltage is needed. It is recommended to keep an AMD processor's voltage anywhere below 1.55v, temps permitting. I notice you have a set of 5B-F chips. I also have a set, and mine were a bit tricky to find the right settings for. Good luck. i've have made a 10min OCCT at 2760 to give you the temps (see graph below) The 2 core have a really defference of temps, is that is normal ? What is your settings for your set of 5B-F ?

What is your settings for your set of 5B-F ? 1) Yes, wrong BIOS settings can and probably will limit your OC. 2) A huge difference of, say, 10C probably means your IHS is a bit off in terms of contact with the core. As for yours, I don't know how normal that is, I'll let someone else take care of it. My guess is though that your IHS is slightly off (8C difference @ 4 min., 10C difference @ 5 min., etc). 3) Everyone's memory controller and memory chips perform differently, so don't count on mine working for you. You can find my settings in the OCDB section of the forum. Share this post Link to post Share on other sites More sharing options...

(first post) 2) this strange may i will try with an other heatsink, witch one is the best for the 939 ? i dont want to remove the IHS i've got this CPU for less of 10 days. 3)I don't find your post on the OCDB could you give me the link, i ll take a look for see the difference with my settings?* Thx for your help and for the time you pass some to try to help me Share this post Link to post Share on other sites More sharing options...
Guest LookBackX2 Posted June 25, 2007 Posted June 25, 2007 sazerty, In response to your PM I will do my best off the top of my head. I am running T-mods 704-bta bios, so my settings will be a bit different than yours. I have made some changes to the settings in your OP. Try out the major changes and see if it helps. I've found it a bit easier to get high OCs with lower multipliers too, don't know why though. Good luck.

Refer to LookBackX2's post above me first. 2) If you''re going for air-cooling, try the Sunbeam Tuniq Tower or the Thermalright Ultra 120 Extreme. I've heard great things about both. 3) Here's my 165 entry Share this post Link to post Share on other sites More sharing options...
