My Opteron 148 OC Experience

**Modulok** · 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.

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. Rolling Eyes

Yeah, the ram should be able to do 300mhz, new bios has this cool thing where you can run ram mhz FASTER than the cpu mhz.

What are you at now with yours Asylum?

With my new ram I was able to get my Opt stable at 2800 (255 * 11).

I run it at 245*11 though Grin

I stuck it at 300*9 and gave up. I've been too busy lately to even mess with it.

Mine is all base, except for the ram. The ram is at 2.84, where suggested is 2.8, DFI expert put it at 2.64.

The ram is originally rated for 2.5-3-3-8, I took ram to 3-3-3-8 allowed me to get it up to 255 stable.
