Overclocking my Opteron 146

Milz · 9 Feb 2006 at 20:18

Hi ^_^

I have an opteron 146, CACJE Stepping, I dont know the batch numbers :S
My Entire spec
AMD Oppy 146 (using the Zalman 9500LED)
G.Skill 2GB DDR HZ PC4000
Gigabyte K8NXP-SLI Motherboard.
7800GT 256meg Leadtek
250gb Western Digital
Pioneer DVD-RW
Tagan 530w PSU (Silent Modular, Dual rail)

Okay, Ive established that I can run stable at 2.5Ghz @ DDR500. with a 2/2 divider. Now when I go to 2.75Ghz @ DDR500. My games run fine, windows boots, I can play BF2, CS Source for hours on end and yet, when I run prime 95, I either crash within 10 seconds, or 6 minutes. Rounding Error. Ran Memtest for 6 hours with no errors.

Ive set my CPU Voltage to 1.55V. RAM at 2.8V Timings 3-4-4-8. Using the divider as 2/1.83. Chipset upped by 0.2Volts.

Is there anyway to make my computer more stable? I would really like to hit the 2.9~3Ghz barrier.

Is it something im doing wrong :S. Thanks for the advice in advance!

try putting the memory divider as low as u can, make sure that the HTT frequency is set to x3 and see if that helps.

Oh yes soz forgot to post the HTT is set to 3x

2.75 might be the fastest your cpu can go, i havent seen any CACJE steppings that go higher than that prime stable. remember that many of these 2.9 - 3 GHz screenshots you see of later batch 146's are probably not prime stable

My opty 144 (cacje)will do 2800mhz so surely the 146 would do more, or does the extra multi not always give the advantage?

the only thing the higher multi will do is let you get as high but without putting dividers on ram as much. wont effect how far you can push it, just how much you have to lower your ram.

I think you should try on a 166 divider; I initially did'nt want to try this as concerned about performance hit but finally did and have noticed no performance hit at all.

Now at 300x10 at 3-4-3-8 prime stable at 1.52v CPU and 2.8v memory with just over 86, 000 in Aquamark so can't be bad.

Okay that didnt work

Buttttt :S

It didnt work so......I i messed around with it, made the Core Voltage 1.65v

Then kept everything the same

Booted then restarted.

BEEP BEEP BEEP, WARNING BIOS CHECKSUM ERRORS

o__o; I **** myself :S It kept doing it till i reset the bios and it automatically backup. It kept failing so I eventually did it after resetting clockspeed settings, then I got into windows on stock, rebooted, CHECK SUM ERRORS again, so I totally reflashed the bios in windows the second time :S.

Ekkkkkkkk, I think i need a DFI

No swearing.
