Dual Core Opteron Thread #2

[vws]

PS
They seem to have changed the design of the oem heatsink a bit.Will try and take some pics.

Thanks SMIFFY for your result posts, and do keep more coming!!!

I've taken a couple of shots of the two kinds of Opteron stock HSF, so you don't have to.. Which one is the one that came with your box, the right one or the left one?

[Smiffy]

Hi All

The one on the left.Noticably more fin area and larger but a smaller fan,seems to be 70mm on new against 80mm on old.
Popped it on my Opteron 146 running 3Ghz in the DFI RDX200.

Back again
Testing stability at 2800Mhz still on 1.3v
Been running Prime 95 dual core test 1 hr so far.

Hi All
Fine at 2.8Ghz.Testing 2.9Ghz on 1.325v

Update on the OC of my Opty 185 -

2880 (240x12) @ 1.40 - Orthos and FAH okay
2940 (245x12) @ 1.40 - Orthos and FAH okay
3000 (250x12) @ 1.45 - Post and CPUz but Orthos failed.

[Smiffy]

Up to 3GHz but needed a bigger jump on voltage.1.425v

But Orthos dont fail with 1.425v?

Hi all... I'm a happy owner of a Opteron 165

Rock stable @ 1.35v on a DFI NF4 Ultra-D. I've tried boot at 300 of HTT with 1.425v, but I got a error in a windows vista file (corrupt file).

My results:

9x289 = 2600 @ 1.30v -> Freezed after a while using Folding@Home
9x289 = 2600 @ 1.35v -> Rock Stable with Folding@Home 24/24
9x300 = 2700 @ 1.245v -> corrupt file in windows while booting

Please tell me somethings:

1. Do you think I can go a little higher?
2. Could it be a problem because I'm using Vista? Maybe with XP Pro I wouldn't have this problem?

Here's the stepping of cpu:

Here's the stepping of cpu:

you sure can go higher, well providing your temps are in check. put 1.45v to her and see how far you can go. imo 1.45 is fine for air with good temps. hell if you have real good cooling i would even go as far as 1.5v

[BRSG]

Ups... forgot to leave here that info and need to correct one thing:

9x300 = 2700 @ 1.425v -> corrupt file in windows while booting

I have a Scythe Ninja heatsink with a SILVERSTONE FM122 120MM fan.

Unfortunately, my currents temps are a little bit high... I need to put some new Artic Ceramic on my cpu.

With cpu fan @ full speed:

Do you think it might be trouble with your RAM? If you are stable at 2.6@1.35, 2.7 should be almost stable with 1.425, if we apply the .1v:100MHz rule that nearly all of these seem to follow. Try 1.45 and maybe play with some dividers and RAM settings

[BRSG]

I have 2x1GB G.Skill PC3200ZX and they are already with the 140 divider, which means that they are at their default speed. I'm giving them 2.7vdimm, but my DFI overvolts them at almost 2.8v.

RAM settings? Eish... don't understand anything of that in these boards Don't know what to change... too confusing

[Repoman]

I have the same RAM, try lowering voltage to 2.6 or even 2.5v (the sweet spot for mine). We'll make it easy, post up an A64 tweaker screenshot so we can see if there's any changes that might help you out

[WoutZoR]

@ BRSG:
I also have the same RAM. Please take a look at this thread about the ZX: http://www.xtremesystems.org/forums/...5&page=1&pp=25

But Orthos dont fail with 1.425v?

Haven't tried Orthos yet but fully stable on OCCT and F@H and 12hrs of Prime95.

Repoman, thx for helping me

WoutZoR: I'll check that thread, thx

Meanwhile, here's a screenshot of A64 Tweaker (I have everything at auto in bios)

No problem. But, your A64 Tweaker SS is screwed up. Keep hitting "Refresh" at the bottom there until the numbers change to something a lot lower, and until the asterisks go away.. you'll know it's right when "Write CAS latency" is 1, that's the only number that works with DDR memory. A value of 2 or above will make the system not boot, or if set in Windows, freeze immediately

That thread basically gives you good starting numbers though. I was gonna give you numbers that I've found myself to be the best, most are the same as in that thread (a few of mine are a bit tighter).

Tried that, but still the same numbers... could it be because of the odd memory divider (140), or maybe windows vista is causing this?

Don't know, but there is another AMD tweaking program (whose name escapes me at the moment) that a member here wrote.. it does the same thing as A64Tweaker but doesn't get messed up.

For now though, you can try the numbers in the thread that WoutZor gave you

[BRSG]

OK, found out that it's a problem with A64 Tweaker... look at this screenshot from Central Brain Identifier

[fanatic22b]

Real quick question.

When overclocking, do yall set the PCI clock synchornization mode to 33.33mhz? I just realized I've had mine on auto the whole time, and have been stuck at a wall at a little above 2.5ghz (278fsb), and my stepping is suppose to be one of the better ones. I've messed around with memory settings, I'm almost positive I can rule it out (OCZ platinum that's underclocked to 180mhz).

[spikespiegel]

nice score!!!

[luismenendez]

I am not very lucky with my opty 170 CCBBE 0615 EPMW

I am getting only 2740 Mhz from it at 1.41v

I tried 2750 with more volts (up to 1.47v) but fails orthos and pi in a few minutes. I tried before with an AsRock dual sata and now with an Asus A8N32 Sli de luxe and still not able to clock any higher. Temps at full load are around 55C.

I though the chip could reach 2.8 - 3.0 but not luck here

I guess my opty doesn't like volts (Tcase by core temp is 59C)
