News... there are currently (as of 31st August) serious problems with compatibility. Majority of boards won't POST with Opteron. I just know Abit AN8 works OK. And the CPU can OC like Venice does, one guy got 65C TCaseMax part and was able to pull 2750 MHz at 1.45V of it (but had no time for intensive stability tests yet).

Where are people buying and clocking these parts? I can't find anywhere to buy one :shrug:

Must be an engineering sample or those cpus handed out to testers. They are still not available for sale AFAIK.

Petr · Sep 1, 2005

They are available for sale in our country - here. It's not an ES.

OC Detective · Sep 1, 2005

Petr have you contacted them directly to confirm they have stock?
The price, is it in czech koruny? If so it equates to around USD161 for the 144. Does the czech republic have any form of VAT?

c627627 · Sep 2, 2005

Plus aren't they in EU, shouldn't it be in Euros?

OC Detective · Sep 2, 2005

They are not adopting the Euro until 2010 and VAT is 19%. So the price for US users will be quite similar to those shown on the AMD site.

Petr · Sep 2, 2005

The price without VAT is 3790 CZK for Opteron 144 tray what is about 155 USD. Considering it is limited number and not AMD's pricelist's 1000 units, it quite typical price. Shortly after launch, it was 3360 CZK (= 140 USD) but then AMD raised prices (without changing them in the pricelist). I was told AMD wants / wanted to adjust prices so that Opteron wouldn't have that excelent price/performance ratio.

We are part of EU since 2004 but we are not adopting EURO until 2010.

They received first batch on 30th August. Few people ordered them and now they have them. If everything goes well, I should receive one for a review from them today. But as I was told there are those problems with compatibility, we'll see if it works in an Asus motherboard or not.

OC Detective · Sep 2, 2005

Petr, look forward to seeing your review.

The review comparing Opteron to Athlon 64 is now online - link here. Opteron 144 OCed from 1.8 GHz nominal frequency & 1.4V nominal voltage to 2.8 GHz & 1.5V. Motherboard used was ASUS A8N SLI with 1011 BIOS.

Vey impresive. Did you try pressing it further than that? It seems like that chip should still ave alot more headroom. I bet it would easily it 3ghz with more voltage and perhaps better cooling.

The motherboard wasn't capable of running more than 313 MHz. At 315, it couldn't even boot to OS while at 311, it could do that at 1.40V (but Prime95 failed instantly with this voltage). I used BOX cooler supplied with Athlons 64 FX and X2 - it has copper core with four heatpipes and a 3000 rpm 70mm diameter fan. The temperature was quite high when OCed - 63 degrees. Maybe with better cooling, it could do more. This chip has 65 degrees TCaseMax !

An impressive overclock petr, hopefully soon some US and UK resellers will wise up and start selling these. I'm sure whoever has them available first will get cleaned out. How is compatability on DFI's s939 line?

Petr · Sep 4, 2005

It was confirmed it works on at least one DFI motherboard.

Back to ASUS - the only problem I encountered was that PowerNow! didn't work. I doesn't matter that much as in idle it is very cool CPU, though.

OC Detective · Sep 4, 2005

Well over 50% overclock - a 2.8GHz cpu with 1MB of L2 cache for only around worst case scenario $150 bucks (perhaps less).
I notice cpu-z needs updated to recognise these processors - reasonable maximum case temperature too!

c627627 · Sep 4, 2005

1. So these are not on the horizon as being available in the US as of now, right?

2. What would you expect a most recent revision, most recent dated Venice to do as of today please? I saw they're down to $120 the other day but it was ewiz, not sure if it's a repuable retailer...

Petr · Sep 5, 2005

Opterons have better cores. Even AMD itself says they have stricter testing procedure for Opterons and that the silicon is better. Therefore Athlon 64 should, on average, OC worse than Opteron.

c627627 · Sep 5, 2005

Thanks, I guess I was just trying to separate old Venice average overclock expectations from new revision E6 ones and put clear price tags to match.

For the record, Venice E6 revisions OEM lowest prices today appeared to be

Athlon 64 3000+ $123.09
Athlon 64 3200+ $138.53

This is the low price range retailers may be heading toward in the coming month.

Dont' forget that the Opteron (E4) 144, 146, 148, ... are having 1 MB L2, and should be compared with the SanDiego (E4), and this makes the Opteron 144 a good buy for price/performance.

144: OSA144DAA5BN 1.35/1.4V (SH E4 rev, 00020F71h) SanDiego, 1 MB L2, 1.8 GHz, x9, 67 W
146: OSA146DAA5BN 1.35/1.4V (SH E4 rev, 00020F71h) SanDiego, 1 MB L2, 2.0 GHz, x10, 67 W
148: OSA148DAA5BN 1.35/1.4V (SH E4 rev, 00020F71h) SanDiego, 1 MB L2, 2.2 GHz, x11, 85.3 W
150: OSA150DAA5BN 1.35/1.4V (SH E4 rev, 00020F71h) SanDiego, 1 MB L2, 2.4 GHz, x12, 85.3 W
152: OSA152DAA5BN 1.35/1.4V (SH E4 rev, 00020F71h) SanDiego, 1 MB L2, 2.6 GHz, x13, 104 W (?)

3700+: ADA3700DAA5BN 1.35/1.4V (SH E4 rev, 00020F71h) SanDiego, 1 MB L2, 2.2 GHz, x11, 89 W
4000+: ADA4000DAA5BN 1.35/1.4V (SH E4 rev, 00020F71h) SanDiego, 1 MB L2, 2.4 GHz, x12, 89 W

A64 940, 754, 939 CPU Models, OPN code, rating (post 5)

Petr · Sep 5, 2005

There are mistakes in those ratings. Model 152 is 104W. You are missing model 154 that is also 104W.

A64s 3700+ and 4000+ SH8-E4 have TDP rating of 85W. 89W was for 4000+ SH7-CG.

hitechjb1 · Sep 5, 2005

These two links from AMD quote the thermal power spec of the SanDiego 3700+, 4000+ as 89 W (but they may have new spec with slightly reduced power for Opteron ?).

http://www.amdcompare.com/us-en/desktop/details.aspx?opn=ADA3700DAA5BN

The Opteron 152 and 154 are similar in terms of frequency, core, revision, to the FX-55 and FX-57 respectively which are rated 104 W in thermal power.
