Help my Opteron 165 reach at least 2.8Ghz

I have an opty 165, a coolermaster aquagate mini r120 (which for some reason my proc does 38 when idle) and an asus a8n32 sli board. My ram is gigaram mach1000 ddr500. To get to 2.8 i need dividerss. I ve tried setting it to 166 and it doesnt boot. Yes my htt is at 3x, multi is 9x and htt is at 300. But it wont boot. Help please.

uhh, what is your voltage? My 165 needs 1.45 volts to do 2.8ghz.

What was the highest that you had it stable?

My point was we don't know where he was at when it got flakey? Did he go from stock to 2.8? That isn't very smart....

I meant the original poster.....sounds like he took it out of the box, put it together and went for 2.8.......ya know that's a bad idea! But that's how I read it.....

I run a 2/3 divider on my ocz 2gig set, so I can run @ 2-2-2-5 @422ddr. You really dont need to oc your memory on a a64/opteron setup, because of the on cpu memory controler(vs the old p4 and athlon xp and lower with the northbridge setup).

My opty 165 only went to 260 (2340) stable. Even higher voltages wouldn't coax it to do 270 let alone 300.

I have since backed it down to 250 which lets me run my ram at a better divider (and cl2). that with 4x HT gives me slightly better 3dmark scores.

My understanding is that the dual cores are easier to damage with high voltages, so be careful.

BTW, I am running RightMark to back off multiplier and voltages and keep it nice and cool even though it's overclocked.

stay under 1.55volts with a cpu fan, and watch your temps on the core. Stay under 50c full load (amd says stay under 60c) and your good. I dont really think 200-300mhz is a big difference after you hit 2.2ghz, but when you get to 2.6 or 2.8 you will notice faster performace (and if you multitask you will really see a difference).

chances are it wont reach 2.8ghz - its the luck of the draw, dont expect miracles.

Chances are you've never used an Opty, it's the luck of the draw. Don't expect miracles (like you actually knowing anything about computers =/).

@Topic: I can reach FSB 290 w/ 1.328v on DFI LanParty nF4 Expert w/ Opty 165, I recently bought it and I would surmise you should be able to get it higher. My idle temps are as low as 18c (Thermaltake Tower w/ 2 Vantec Tornado's) and less than 30c full. Your WaterCooling setup sucks, water is a waste anyways, grab a nice Heatsink and some Tornado's.

My Opty 165 is @ 2.7 (300x9) @ 1.4v.

I'm happy with my P4 doing 3200MHz, which is the stock speed.

Good advice. I wanted to double the speed of my old P4 1.6GHz Williamette core. So I got a whole new computer

At 40 C idle you want 2.8 GHz ?

Try 10 C idle, that might work.

Some Opterons will only reach 2.35 GHz before giving up, others 2.5 - 2.6 GHz. Overclocking a lower end Opteron to 2.7 GHz is asking for problems, as you no doubt have noticed.

Woah, that's a bit bad. I have mine @ 290x9 @ 1.4v and I am 22c Idle and 30c Load, I have the Thermaltake Tower w/ 2 Vantec Tornado 92mm though.
