3000+ Venice OCing

[Mazumo28]

Well, I was wondering if I can hit 2.7GHz on an AMD 64 3000+ Venice with my future rig. Here's what I plan to do:

2700MHZ = (9 x 300) at 1.55 vcore (do I need higher?)
Put RAM on a 3:2 FSB:RAM divider to run at ~192MHz (stock of 200)
Lower HT to 3x

Here's my future rig specs:

Epox 9NPA+ Ultra
AMD 64 3000+ Venice
(2 x 512) Corsair VS
XP-90 w/ Vantec Stealth 92mm

Is my setup good for this kind of overclock?
Do I need higher vcore?
Do I need to do anything with RAM timings?

Thanks for your help

probably not that speed stable with a newer (E6) chip, no
but it's certainly possible depending on the chip

some of the newer ones can't hit 2.4ghz

 

[Mazumo28]

I thought E6 stepping was better. Oh well
What about a 3200 at 2.6?

 

[the cobbler]

you just never know, every chip is different

luck of the draw 99% of the time unless you know a) exactly what week/stepping/batch codes are the best and b) that any of them are available and c) that you can find one

likelihood of those three things coming together is not too great, especially considering that the best OCing Venice were the first few weeks really and for the most part those are long gone

and even if you do find one, it may be a crap overclocker

that's what makes this so much fun


I looked long and hard for mine, paid too much for it and it still didn't do what I had hoped, lol

OC is always a gamble, even if you get a so-called "good chip" since each chip really is different. You may very well get a E6 that can do 2.7 GHz. Those do exist but likely you won't. Just keep your fingers crossed. Otherwise just wait for the Opteron 144/146s to come in stock . . .

I'm one of the "lucky" ones I suppose. I got my 0519 for cheap ($110 shipped) and it 2.7 GHz . . . you may not be so "lucky" . . .

I just built a 3000 E6 with MSI K8N Neo2 Platinum and this GIGARAM MACH 1000 2x512. They are $125 but are pretty nice for the money and they have TCCD chips.

Both FSB and memory running at 250. Currently have timings at 2.5-4-3-7. Still adjusting timings as I can get MEMTEST to run fine but PRIME95 will give random " got .5 and expected .4 or less" error and stop. This happens anywhere from 1 to 5 hours.

First OC so I am pretty happy with it so far.

get better ram. dont expect anything fancy with value select.

value select is just fine, use a divider. It certainly won't limit your overclock or have a massively negative impact on performance, if that's what you're getting at. Just keep it between 200-230mhz

See? nothing wrong with value ram, even the junky chips:

SuperPi 32M

SuperPi1M

it's no TCCD or BH-5, but it works if that's what the wallet allows

Yup I was running 1GB of PC4800EL Plantinum OCZ fancy stuff on my 3000+ @ 2.6 Ghz. Now I've "downgraded" to 2GB of PC3200 OCZ value stuff (2.5-3-3-7) at the same 2.6 Ghz. You don't need good RAM to overclock on A64; memory dividors are just fine and performance doesn't die if you're not on 1:1 like on the P4. The onboard memory controller is to thank for that.

I can find some 3000+ processors at have E3 stepping.
Would that at least be better?

 

[Muggy]

Can u actually go to a shop and see the stepping and buy it ? If so, u will be able to select the chip. If ur buying online, then its a gamble. Try to get ur hands on this one : ADA3000AA4BP ( Venice ) and the stepping : LBBLE 0531 *PAW.

If you can find them, buy them. My 3000+ Venice E3 hits 2.8 GHz, but I run it at 2.7 GHz.

You're probably better off looking on Ebay for a early E3 Venice (i.e. 0517) Yeah Week 17 are rare but I've seen several of them on Ebay in the past few weeks . . . otherwise the E3 Venices you'll find at retail stores will probably be week #0s and those aren't exactly great OCers . . .

Like I said, if you can wait a month or so, get a Opteron 144 . . .

 

[Mazumo28]

Well, I've found something that may be an E3 stepping on ebay. It doesn't exactly say, but heres the "markings" on the cpu.


AMD Athlon 64

ADA3200DAA4BP
LBBLE 0518DPCW
Z646696E50174

What do you guys think?

EDIT: I may get an Opteron 144 like some of you guys suggested.

Do you think the price on the Opteron 144 will fall in time?
How do you think it compares to the AMD 64 series?
Will AMD develop these with different steppings or revisions that could be bad for overclocking?

Thanks

get an Opteron 144

if not, I can get you in touch with a broker who can get you as many new 0517APAWs as you want (40 last I checked).

BUT, they are a whopping $219 = lot of cash for a 3000+ Venice to put it lightly.

in all fairness, I looked for a NEW 0517 for several weeks before finding these, and I definitely feel like $219 was a bargain for near- FX-57 speeds. But if you were to buy one of these and it was a crappy overclocker, I would feel like a real jerk for recommending you spend $220 on a chip you couldn't gotten for $125.

Wow, that's a lot for a 3000+ Venice. I got mine for $110 and it does 2.7 GHz . . .

The Opteron 144s aren't that expensive (in the $150 range) and once they get into stock (which should be soon) they will drop in price a little. But still $150 for a chip that is basically a locked FX chip is well worth it IMO . . . 2.8-2.9+ GHz @ stock vcore is no joke . . .

The 939 Opterons are basically Athlon 64 San Diegos under a different, "professional-grade" name. The fact they are workstation and server certified chips doesn't hurt either.

$219 for a Week 17 Venice may be worth it if you can get it to do 2.8GHz but just wait a few weeks, and you will likely be able to get an Opteron that does that at stock vcore and with 1MB L2 Cache to boot . . .

Agreed.
