 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.

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
Passed: 262,263,264
Failed at 265
Bios: FSB 264 & 1.45v
Try 265 again...passes
266 fails
Bios: FSB 265 & 1.475v
Try 266 again...passes
267 fails
Bios: FSB 266 & 1.5v
Try 267 again...failed
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.
266x11 @ 1.5v*104%
Failed SuperPI 32M
265x11 @ 1.5*104%
Passed SuperPI 32M - 28:40

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.

Didn't make my 8hr mark but I figure it's some little timing I'll have to fix, maybe not when I am shooting for 290FSB.
-----------------------
FINAL OVERCLOCK
-----------------------
Changed FSB to 290 and multi to 10x...gave dram a little more volts with 2.7v.

Passed SuperPI32M, OCCT, 3DMarks.

So close to my 8hr mark again...I figure the ram can handle the 290mhz so I tweaked the vcore. 1.4*110%.

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 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.

With my new ram I was able to get my Opt stable at 2800 (255 * 11).
I run it at 245*11 though  |

nice, that's also what I'm hoping to settle at..but 300x10 would be nice
how many volts to your cpu? |

CPU is stock @1.4V (1.37V actual)
NB 1.6V
RAM @ 2.8V
Running at 22C idle 30C load on water.
