Priming now at 3060 @1.58v - ran 6hrs+ last night

Do you remember batch on it? ( got 2 with same stepping here soon untested )

Sorry, did not record the batch info.

Okay I reapplied AS5 so I had the chance to look at the stepping.

CCBBE 0617EPMW

hope that helps.

This cpu has a default vcore of 1.35 right? why cpuz read 1.296? is it possible that my PSU is undervolting that much?

don't trust software voltage readings. they are wrong 99% of the time...

Thx for info...

I tested one of my new Opterons this day...and i did get very happy with it so i saved they another two to test tommorow.

What stepping do you think this have then? :P

So can we assume the auto voltage is setting 1.35V correctly? My bios reads 1.41V. The Epox software reads 1.41V at stock, though it drops under load to 1.38V, and goes up to 1.45V at idle.

I can't top around 2.50 GHz stable at stock voltage, and even with + 0.125V I can only hit around 2.6 GHz. (dual prime95 testing). Temps are like 48C load, though CoreTemp reports like 54/58C.

Is it the ram divider? I'm forced to use DDR300 or DDR233. I've tried to avoid fractions in my ram clock speed, but that doesn't seem to help.

My motherboard is an Epox 939 Ultra (9NPA3 Ultra), which supposedly is a great overclocker according to Anandtech. I can run 300 FSB fine if I set CPU to stock speeds.

probably a silly question, but did you remember to change the LDT multi?

Hi I'm runnin:

DFI Ultra-D latest bios
Opty 165
Corsair pc3200 TCCD capable of doin 250ish
7800GT stock
2x250Gig Raid 0

Cpu, Gpu and Mobo watercooled, extra fan over mobo for some cooling on ram and mosfets..

Stability problem seems to be over after reinstalling the dualcore driver with help from the guide.

At this moment I have my system running 300x9 1.35V 9 1/2 hours orthos stable:fact:

Do you mean the HTT? It's at 3X.

The system runs fine at like 300 x 7, so I think the motherboard is stable. Maybe my 165 is just a 2.5 GHz kind of chip.

So you are trying to shoot for 3.0 ghz I guess right? Well most Optys no matter how good the stepping, need at least 1.5 vcore. If stable, keep lowering the Vcore until it gets unstable again to see whats your minimun vcore for 3.0. The thing is try, and try, and try, until you find your best. So don't get dissapointed to quickly, this Optys are good man. So crank up that vcore, set 334 mhz, and check again with orthos (set priority 9). Remember to relax your HTT (3x should be fine) and check your mem settings too. If unstable, could be your PSU, you have a Raid setup, and a geforce 7800 dude, don't espect too much with a 450 watt powersupply. :toast:

I'm expecting my new opteron 165 to arrive the next days. Whats it's default vcore and how much can you recommend with a single radiator watercooling setup? And since this is going to be my first OC'ed DUAL CORE, do I have to run 2 instances of orthos?

No you just need to run 1 instance Orthos can run both cores is same proggy

i forgot to mention a problem i had. when i first got this chip i couldnt get it stable no how! crashes, blue screens etc. i tracked it down to my memory, and i see you have the same stuff! after i swapped my OCZ out with the memory from the wifes rig it ran the way it should! if you have access to different mem, swap it out. i bet thats your prob ... actually, just remove one stick, if i remeber right thats all i had to do. but of course i had to take both out in the end because i needed my 2 gig's ;) seems opty's are picky about there brand lol

Ok a little update. Now the temp is below 60C at all times and I'm finishing testing 2.9Ghz at stock vcore (only orthos left for testing but so far everything rock stable). This CPU was the best $179 I ever spend and will hold me nicely before changing the s939. Sandra is reporting higher results than FX62 is it accurate? What's the safe temp for those things? I'm definitely sure I can reach 3.0Ghz with some extra vcore or maybe even without it...

Thanks man! What ram did you swap in to get it to work? I was thinking of selling the OCZ and buying some DDR500 ram, but they all seem to be out of production. :(

I will try running on one stick though.

i'm using 2 1024 sticks of generic samsung pc3200. i have had them in for about 3 weeks now and its been running fine. 8-4-4-3 1T instead of 6-3-3-2 1T that my OCZ can do, but as far as gaming goes, its makes no diff for me...

take out one stick of you OCZ, i bet it will stablize. mine did after i took one stick out. i'm only suggesting this as a test to narrow things down some.

just wanted to post my results from my first real attempt at overclocking. Used a few different A64 guides to get me thru the process... still not 100% there i don't think but definitely satisfied for now...

Opteron 175
CCBBE O617EPMW

Max FSB got to about 285 on the board
Max CPU i was able to achieve was about 3008MHz on 1.42 - 1.45V

Settled on
265 x 11 (2915MHz)
1.39 - 1.4V
166MHz memory

Orthos stable for a few hours but still testing

Coupla questions though:

HT Link = ??? - I don't really understand this part
Right now it's set at 2.5.

Is that why I only get a 208MHz on the memory?

By my calculations, a 265 with a 5:6 (166MHz) should equate to about 220MHz right?

anything else I'm overlooking or should re-evaluate?

thanks.

Memory dividers on a64 chips are weird, look at the memory divider table in post 7 here:
http://www.xtremesystems.org/forums/...ad.php?t=41595

If you're running an 11x multiplier and a 166 divider so you'll get a true memory divider of 14. So your real memory speed is around ~208mhz (2915/14 = ~208) :D welcome to the A64 memory controller.

As far as HT link goes, that's the hypertransport multiplier - you multiply that by the FSB and that gives HT link speed. The rule of thumb is to get it as close to 1000 as possible but not go over. If you run with an 800mhz HT there's really no downside as the HT bus isn't usually a bottleneck anyway.

here you have very helpful stuff

ahh - ic

halo - maryo - thx for the info...
so ideally, FSB x HT link shoud = or < 1000

265*3 = 795
265*4 = 1060

so i guess ideally at 265MHz, the ideal HT link would be 3 right?
