The Official Opteron 939 Overclocking Thread

[gundamit]

Where did you guys get these things? I want one! Are they out already cuz I checked Fry's already and they dont have any.

Very nice oc's guys!!

Thanks. Wish I had more time to tweak during the weekdays. I'll try to do as much as I can but I expect by Wednesday they'll be another big group testing the same CPU and much more info available. If you read through the threads you can see who we're getting the CPUs from. Apparently he's swamped with orders now so I'm not sure if he wants the source advertised openly.

@dogsx2 - Rumor has it you have a 146 on the way. Do you have another board to test on?

i want someone to pop the ihs off, and see if there happens to be an 's' on it like some fx's we've seen, just outta curiosity

As hot as they're running, someone will take a blade to it soon I'm sure. So what would the "S" be an indication of?

No, not sure what I'm going to do. Yes, i have a 146 coming this week. If Team Japan is any indication of how it will do, it looks like about the same as the 144.

Good job on the 3000MHz.

[dogsx2]

Still on single channel but can't quit playing with it.

@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.

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.

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.
