Posted: Tue, 04 Jul 2006 22:28:43 Post Subject: My Opteron 148 OC Experience
I decided to start a thread that I can log exactly which steps I took to OC my new Opteron 148 on my DFI LanParty SLI-DR motherboard. I also want to share this here for any comments, suggestions, questions, etc. I will update this post as I go along.
My setup is the following:
DFI LanParty NF4 SLI-DR [official 04/06 bios]
AMD Opteron 148 2.2Ghz [CACJE.0604]
Thermalright XP90C [Copper CPU Heatsink]
GSkill Extreme Series DDR600 TCCD [2x512mb]
eVGA 7800gt co 256mb
Hitachi 80gb Sata II
OCZ Powerstream 520 watt
Pioneer 16x Dual Layer DVD Burner
For testing stability and benchmarking I used the following programs:
SmartGuardian
CPU-Z
Clockgen
A64 tweaker
Aquamark3
3dmark03, 05, 06
Everest Home Edition
Sisoftware Sandra 2007
Memtest [Windows version]
Super PI
OCCT
Prime95
The first thing I did was test the system at stock speeds. It was kinda a challenge at first because the GSkill timings that had worked at ddr600 with my old A64 Venice weren't working with the Opty148. After some searching on DFI-Street and XtremeSystems I found some ram settings posted by the GSkill Technician for the exact motherboard/ram I am using. With these settings in place I did a fresh install of Windows [XP Pro with SP2] and installed the necessary drivers and programs.
FSB: 200
LDT: 5
Multi: 11

Time to test the stability of the ram; which is the reason for problems I had with stability. I run memtest in windows for 20mins without errors. [previously I got errors within a minute]. Then test 4M Super PI, which causes the program to not respond before, it passes the 32M test as well. Passed OCCT and all Video benchmark tests [Aquamark3, 3DMark03, 05, 06]. Primed 12.5hours.
OK, I have found good stable stock settings. Now I will start to find max mhz for the Opteron 148.
-----------------------------
FINDING MAX CPU MHZ
-----------------------------
I make a few changes to the stock settings in the bios. Changed LDT from 5 to 3; dram from 200mhz to 100mhz.
Start CPU-Z,ClockGen, SmartGuardian, task manager and OCCT. I keep an eye on temps with SG and overall mhz with CPU-Z, watch the 100% load on task manager, start OCCT test. Once I get a 100% load I start upping the FSB/HTT on Clockgen 10mhz at a time and wait for OCCT to not give me an error for at least 30secs. [I chose OCCT because it seems to fail more than superpi and also has a timer already counting for you]
FSB Listed passed at least 30secs of load unless noted:
210
220
230??? -restarted system [maybe it didnt like the big jump]
225,226,227,228,229
230,-239
240-249
[Temps still good, between 38-41 with load]
250-259
260,261
262=froze pc
Restart, Change bios FSB to 250; Boot into windows at 250x11 & Resume testing
Upped FSB to 261.87...fails OCCT...looks like max is 2872mhz @ 1.4v [261.1x11]
Restart, Set Bios to 261FSB & 1.425v
Load windows, set fsb to 262 and run OCCT
I don't want to take it pas 1.5v because I will not run it daily that high. Temps are still decent around 40-43. As of now my max cpu mhz is roughly 2930mhz.
--------------------------------------------
MAX CPU MHZ = 265X11~2915MHZ

Made a few changes in bios. Started CPU-Z and SG for monitoring, then ram memtest for a few mins. No errors yet. Up FSB up to 305 and I start getting errors. Since I don't plan to use DDR600 with my max cpu I figure max is somewhere between 300-305.

EDITED
---------
July 5 6:55am - updated stock benchmarks and prime length
July 5 6:15pm - updated full stock settings & added finding max cpu section
July 5 10:45pm - testing max stable cpu mhz [SuperPI 32M Passed] currently at 265x11 @ 1.5*104%
July 6 8:40am - updated end of max cpu mhz, found max cpu at 2915mhz
July 6 8:30pm - started max ram section...Testing DDR600
July 7 8:55am - Ram stable at DDR600 2.5-4-4-8 1T...prime test started
July 8 12:00pm - 8hr prime blend test failed at 7hr 8min. Lowered vcore to 1.4*110%. Currently doing superpi, occt, prime.
July 8 9:00pm - Found stable OC of 2900mhz DDR590 - Updated final benchmarks and final OC settings _________________

Nice I'd like to see where this ends up. I got my opteron 148 up to 2.7Ghz stable and kinda gave up cuz it wouldn't do 3Ghz so i quit. _________________ There is a very fine line between "hobby" and "mental illness."

I stuck it at 300*9 and gave up. I've been too busy lately to even mess with it. _________________ There is a very fine line between "hobby" and "mental illness."

nice, that's also what I'm hoping to settle at..but 300x10 would be nice
how many volts to your cpu?
gonna have to look when I get home, it's been a while and I'm at work now. _________________ There is a very fine line between "hobby" and "mental illness."
