What are your Opteron 165 o/c settings?

Im at 2.5 and failed Stress Prime on core 0... i know i have something set wrong... what do you have everything set at? and memory voltage... whats good for that?

First... give us ALL of your settings.

Open up A64 tweaker, CPU-Z...( 2 instances, so we can see mem, as well)

Thanks.

i dont have a64 tweaker, and i have no idea how to take a screen shot

Here is A64 Tweaker. If you want to take a screenshot than just hit the "Print Screen" button generally found on the upper right-hand side of your keyboard. Go into Photoshop (or similiar program) and paste the image into a new file. Save the image as a .jpeg and than upload to a popular image hosting site like Imageshack.us (it is free). After the image is uploaded to their site, they will provide a direct link address (usually the bottom option in the options they give you). Just take that direct link address and post it here on Anandtech.

The other way is to just take some bios screenshots with a digital camera and upload them the same way you would a normal screenshot.

ok now what do i do

What is your RAM clock? What kind of cooling are you using and what temps are you getting at 2.5 GHz?

I personally have a 165, but I can get up to almost 2.6 GHz at stock voltage. I'm now running at 2.7 GHz (300x9) with a 5/6 divider (RAM is running at 245-250 MHz). My timings are 3-3-3-5 with OCZ El Platinum 2x1024 MB. I would take screen shots, but I am not at home.

You might have gotten a stepping that is not a great overclocker. 2.5 GHz is still not bad at all, but it might be your RAM limiting you. Try to isolate the overclocking of each component individually:
1. FSB
2. CPU
3. RAM

Determine the maximum overclock of each one by removing the other two as variables, which you can accomplish by underclocking the hell out of them. If you want to determine the max FSB, you can set the FSB CPU multiplier to something tiny like 6 or 7 and set the memory divider to 1:2 (making the effective RAM frequency half that of the FSB frequency). Then keep setting the FSB higher in increments (and vcore if you have to and want to) and booting into windows and testing stability with two instances of superpi 32M. When you can't test anymore and you've found your max, move onto the next component. When you've found the max of all three, you can combine them using a memory divider.

Does that all make sense?

Go to www.dfi-street.com and go to the AMD overclocking forum. At the top is a great guide, even if you don't havea DFI board.

Will someone just tellme what you are running as i asked for... Like everything. Memory, cpu, HTT. volts and everything.

2GB G.Skill HZ sticks
Opteron 165
HTT = 311MHz
1.4V
everything = ???

Still tweaking mine a bit. It's a 165 0551 UPMW. 2700 (9x300)is stable @1.500v even on the stock sink with memory at 9/10 (270) 3-3-2-0-1T (Mushkin XP4000 Redline 2GB kit).

Right now I'm working on 2835 with a Swiftech Apex Ultra. It seems to be pretty good at around 1.6-1.65v. I haven't re-tweaked the memory yet. HTT is at 3.0x but I'm pretty sure 4.0x will run fine as it does at 2700.
