The Official Opteron 939 Overclocking Thread

[gundamit]

@dogsx2 - I'm guessing the 3ghz 32M SuperPi stable club will be growing pretty big by Wednesday. Congratulations on that mark on air! I have a Thermaltake Typhoon I'm going to use to try to do the same.

I have a 146 coming too. I thought I might need it if I had a problem with the HTT crapping out too low. Doesn't look like that'll be a problem now though.

I did the same thing, I figured between the two of them, one should be OK. I also bought a BT for the x2 but with a s cat fan on my Hyper 6,not much diff. I hate to buy another board with all the new ones coming out soon but will have to rma this one and don't have another.

I think this should put to rest the thought that the opertons 939's are just a sd .

Once we get a look a Optys outside of the initial production weeks we'll really be able to see if they can separate themselves from their SD brothers. In the meantime we need to push on the memory controllers (more bandwidth) to see if we can get FX owners to flinch just a little.

Hello,

I just got my new CPU and want to start overclocking.

some specs...

Asus a8v deluxe
2gb corsair TWINX2048-3200 3-3-3-8
Antec 480W True Power
Thermaltake Tsunami Dream Case

some stock non overlclocked settings

2:1 DDR 400
bank interleaving AUTO
Burst Length 4 beats
CAS 3
TRAS 8
TRP 3
TRCD 3
TRRD 2T
TRC 11T
TRFC 14T
TRWT AUTO
TWCL AUTO
TWR 3
aysnclat AUTO
read preamble setting 5.5ns
2t command DISABLE

CPU FSB 200mhz
CPU mult 10x
CPU voltage 1.350v
agp/PCI 66.66/33.33
vdimm 2.8v

Seems that the ram and cpu combo are a little sensitive. Any suggestions on how to relax the RAM timming so I can get a decent overclock and still get past system post.

Nice chip under water

3GHz@1.39V under water

[knopflerbruce]

New Opty 152 has arrived!!

I will do some more SERIOUS testing on this one as soon as I can get some better cooling (TEC etc), I have a strong feeling it's much, much hotter than what core temp says.

In fact, the temp DROPS by 1 degree when I go from idle to orthos lmao. Just can't be right, even if it's a naked core on water.

[[ITA]SEREUPIN80]

nice cpu

I don't think I ever stop fiddling with my overclock lol

When winter roles around again I'll be back on 3ghz and I don't think I ever push my memory enough despite how long I have had this setup

i'm wondering if my mobo is lame.. and that's why my results are so much slower than you guys

[gundamit]

Did you ever move off your stock cooling? dogsx2 has some pretty good air going. I'm on water. Might be the CPU (luck of the draw) since I think we had a little less voltage for the same clock speeds than your chart indicated. Still, way too early in the testing to draw any conclusions. When we have the next batch in the hands of more users, the truth shall be revealed.

[ozzimark]

yeah, i'm using water right now. takes about 1.6v to get 2942mhz sPI 1m stable, where as you guys are doing 3ghz with 1.4-1.5v

it could be that i simply have a bunk core too.

Looks like u gonna have to test tht chip on another mobo 4 sure, you know anybody who can test it for you? Cos u got a new mthbrd also (i think i remember u sayin it was new) you dont know how tht mthbrd performs.

Im sure i dont need to mention this but I will, LOL try to take pieces out of the equation, i leave my explanation at tht,

heheheee

my thoughts exactly. i'm gonna try to get another one just to find out for sure
