    DreamCatcher's Opty 165

    Now that DreamCatcher
    is together it is time to try some overclocking.

    The primary parts:
    MOBO: Biostar Tforce 6100-939 (Bios CU51M811RH2*)
    CPU: AMD Opteron 165, CCBBE 0610
    HSF: Zalman CNS9500
    MEMORY: g. skill F1-3200USU2-2GBHS (2 x 1024)

    The settings for the 6100-939 were acquired from rebel haven* http://www.rebelshavenforum.com/sis-bin/ultimatebb.cgi and StompinRound’s thread @ amdmb http://forums.pcper.com/showthread.php?t=417506. Won’t show all the bios settings, but I can list a more detailed version if requested. Basically I followed what was recommended at the above sites. Memory “timings” were derived from several sources and ended up being a hybrid. The following has become my “fixed” settings:

    Vcore: 1.500V
    Memory Voltage: 2.80V
    CPU Frequency: 250
    Hammer Fid Control: 9X
    HT Frequency: 3X
    PCIE Clock: 100
    Memclock: 166
    1T/2T Memory Timing: 1T

    DRAM > Tcl: 3, Tras: 8, Trcd: 4, Trp: 4, Trrd: 2, Trc: 7, Trfc: 14, Trwt: 3, Tref: 166 @ 15.6, Twtr: Auto, Twr: Auto.

    When all was said and done this gave me 2.25 GHz with a stable run of 14.5 hours using Orthos for a dual core test. Supposed core temp(s) were low to mid 50s C.



    Now on to ClockGen and SuperPi to see what the “top” will be! Not sure if this is meaningful, but it sure looks impressive…….. 2.91 GHz ad would run SuperPi all day long.



    On to the “stress” test, for me this would be getting closer to the “real world”. On a side note it seems Orthos will not run at the ClockGen settings so at this point I went with a dual core setup for Prime95 that uddarts provided me http://www.diy-street.com/forum/showthread.php?t=16446. It is right simple to set up (has to be for me!) and I know for sure that it is affected by the ClockGen settings, as it would defiantly crash! As per instructions one thing to really, really remember..…split your memory because it will try to use the entire amount on just one core. As I have 2 x 1024, I set the (in options) memory to 800 each for a total of 1600, leaving spare for “other stuff”.

    BTW would anyone have an idea if I were to bump the memory split up to say, 925 each this would improve or degrade what I’m doing?

    Well different numbers, but they appear to be good……… 2.67 GHz, with my usual impatience stopped the test at 3.75 hours.



    The temps again would run mid to upper 50s C, even though SpeedFan showed low 60s. However my system shut down in bios is set
    at 60C so I kinda went with MBM’s 57C. Also as another side note you will see in the screen shot that MBM and WCUPID would only show the boot setting of 2.25 GHz

    So there you have it my 1.8 Opty 165 does 2.25 in everyday mode, and with ClockGen it will do 2.67 in Prime95 and 2.91 with SuperPi……. so wada ya think? And yes I need to keep the side panels and top off the MicroFly or she will do an overheat shutdown when running above 2.575.

    EDITED FOR PIC SIZE

    Re: DreamCatcher's Opty 165

    That's OK I guess.

    My 165 Opty has been running like this since early december at 100% CPU util folding protiens.

    Vcore: 1.35V
    Memory Voltage: 2.70V
    CPU Frequency: 300
    Hammer Fid Control: 9X
    HT Frequency: 3X
    PCIE Clock: 100
    Memclock: 166
    1T/2T Memory Timing: 2T

    DRAM > 2.5 3 3 7

    My opty 170 has been doing the same for about 3 weeks.

    Which Piano should I buy if I want to play like Mozart?

    Re: DreamCatcher's Opty 165

    Okay played around a little bit and these are my max "bootable":

    293HTT @ 100 = 2.64 GHz with dual Prime95 test for 4+ hours
    294HTT @ 133 = 2.65 GHz currently running the dual Prime95 test.

    With the case open SpeedFan shows core temps of 58 - 61C (MBM in mid 50s) and bios shut down of 60C

    Buttoned up the case and core temps in SF showed 60 - 64C (MBM upper 50s). Case temps were in the low to mid 30s, so finished the testing with the top panel off.

    typo "later today"?

    so you got past that brick wall of htt 250. good!


    it may well exist with your msi board. with the 175 you shouldn't run into it with the higher multi. my neo-4 platinum has it when using the 9 multi.

    Re: DreamCatcher's Opty 165

    Hey Jedihobbit, I have the same mobo and cpu as you do and am able to run it at 2.8 ghz (311 fsb) all the time. I think my mem clocks at 166, but it might be set to 133. Nevertheless it runs at around 207mhz, I'd check for sure but I'm not at that computer right now. My voltage is at 1.42. Temps are around 50C load with a Thermalright SI-120 and low speed Arctic Cooling 120mm fan.

    I'm using the stock, crappy Biostar NB cooler, the one with the smaller fins no less. This is with all case fans set to low speed. My case has excellent flow though. I heartily recommend the Antec Nine Hundred. It's easily the best case I've owned.

    Re: DreamCatcher's Opty 165

    kbohip, checked your system and noticed you're running Patriot mem. I believe this mobo prefers that brand from what I've come across. However you say you can boot up at 2.8 and game, yada, yada? Me hat's off to ya!

    Re: DreamCatcher's Opty 165

    Yea, I've been playing a lot of Test Drive Unlimited lately. I tried Stalker but I just don't like it. I did have one crash in Stalker but I think that was more the game than the system as TDU runs perfect. I've also 24 hour Primed this oc and it ran it fine. As for the memory? I guess I got lucky as I just bought the Patriot as it was the best priced high performance memory at the time.

    Re: DreamCatcher's Opty 165

    With limited time decided to tinker with ClockGen using the 133 Memclock setting as it had the “highest” bootable OC.

    The best Prime95 tested (5 hrs) ClockGen setting was 317 HTT for 2.85 GHz
    The best SuperPi ClockGen setting was 331 HTT for 2.98 GHz

    So to kinda cap off my first foray into overclocking the 939 I have the following:

    “Bootable” settings >>
    200 / 200 = 1.80 GHz = stock
    293 / 100 = 2.64 GHz = 146% increase
    294 / 133 = 2.65 GHz = 147% increase
    250 / 166 = 2.25 GHz = 125% increase

    ClockGen “Stable” >>
    xxx / 100 = Not Tested
    317 /133 = 2.85 GHz = 158% increase
    296 / 166 = 2.67 GHz = 148% increase

    ClockGen Super Pi >>
    xxx / 100 = Not Tested
    331 / 133 = 2.98 GHz = 166% increase
    323 / 166 = 2.91 GHz = 162% increase.

    Sadly, after my first foray into overclocking the 939, I’m still somewhat (mostly) clueless about what I’ve done and its usefulness. Lord knows ud has tried to explain! My take so far is this - CPU power goes up at the expense of “degrading” the value of the memory. It would also be my understanding that this performance “cap” could well be the memory itself.

    Soooo…….
    1. Which one is really the “best - real” performance increase? Guess need to run something like Sandra or PCMarks at each setting?
    2. Does this mean I can set the ClockGen “stable” value each time I want to run a game to get max CPU performance?

    Re: DreamCatcher's Opty 165

    05/03/07

    Took some time today to compare “performance” of the values I’ve come up with. In other words try to answer the prior Question #1.

    I ran PCMarks ’05 for the “full function” issues and then 3DMarks ’03, ’05, & ’06 for funzies. I ran the original value of 250 HTT @ 166 Memclock = 2.3 GHz, my highest “bootable” value 294 HTT @ 133 Memclock = 2.65 GHz, and finally my highest “Prime stable” ClockGen value which is 317 HTT @ 133 Memclock = 2.85 GHz.. The highest value between the three will be noted in red. While it may or may not affect the 3D scores, the 1950 Pro was running my del 24” at its “native” resolution.

    250 HTT @ 166 Memclock = 2.3 GHz

    PCMarks ’05 = 2132
    3DMarks ’03 = 15486
    3DMarks ’05 = 9686
    3DMarks ’06 = 4760

    294 HTT @ 133 Memclock = 2.65 GHz

    PCMarks ’05 = 2084 (1197)
    3DMarks ’03 = 15939
    3DMarks ’05 = 10037
    3DMarks ’06 = 4930

    317 HTT @ 133 Memclock = 2.85 GHz

    PCMarks ’05 = 2924
    3DMarks ’03 = 16071
    3DMarks ’05 = 10216
    3DMarks ’06 = 4997

    Okay no surprises here in that the 2.85 GHz ruled. Still not convinced that “degrading” the memory values to get GHz was a “real” increase of “power” I looked at the percentage of increase and……

    2.85 vs. 2.3 = 24% increase
    PCM ’05 = 37% increase
    3DM ’03 = 4% increase
    3DM ’05 = 5% increase
    3DM ’06 = 5% increase

    But in the realm of “real life bootable” you have

    2.65 vs. 2.3 = 15% increase
    PCM ’05 = 3% decrease
    3DM ’03 = 3% increase
    3DM ’05 = 4% increase
    3DM ’06 = 4% increase

    Very interesting…. I ran PCMarks twice to make sure I wasn’t seeing things. Before I make any “final” conclusions I think I’ll run PCMarks ’05 on my highest “bootable” 200 Memclock value. Also it is very obvious that 3DMarks is a primarily GPU driven and is a non-factor.
