90 nm A64 for S754, FINALLY!

Anodyne · Post by **Anodyne** » Thu Jan 05, 2006 7:12 pm

Any socket 754 users out there have enough experience with a 3700+ clawhammer to tell me if it would truly be worth upgrading from a 2800+? Those are drying up in the online marketplace (but still available for +/- $200 in places)...When I originally bought my parts, I anticipated eventually being able to upgrade to a 3700+ to prolong my system's lifespan - My 2800+ doesn't feel particularly slow to me yet, but I worry that if I wait much longer to upgrade there won't be any 3700+'s left!

oh my gosh.

you will see lightspeed vs mediocre speed.

the 2.4 1meg clawhammer runs as fast as a 2.2ghz 1 meg 939 chip. sometimes in games faster.

Only downside to the Clawhammer is that it's 130nm, which will make it harder to cool. With an undervolt I bet you could tame it, though. Not sure what to expect for a Clawhammer 3700+ at stock speed, maybe ~1.35V, which would reduce heat output by about 25%.

Thanks - I have browsed the CPU charts on Tom's Hardware, but I always take those benchmark charts with a grain of salt. Finding a 3700+ S754 Clawhammer is kind of hit and miss right now, but I have seen them around...Newegg has them in stock but $325 seems too pricey... they also have the 3400+ S754 Clawhammer still available for $199, that's probably a good alternative ($200 is about my limit for a CPU upgrade).

Newegg had the 3700+ on sale for about that much before Christmas, and I could kick myself for not grabbing it then.

frostedflakes · Post by **frostedflakes** » Sat Jan 07, 2006 1:05 pm

Yeah, for $300+ you have much better options that the 3700+ Clawhammer. Your motherboard has pretty good support for mobile processors, I'd look into a higher-end Turion, Newark, or 3400+ Venice (if it ever makes it to the market) if you were going to spend that much. All are 90nm and should be very easy to cool.

But if you can find one for around $200 that's a different story.

~El~Jefe~ · Post by **~El~Jefe~** » Sat Jan 07, 2006 3:48 pm

hey um newark. can you explain them and what boards can they run on?

I am assuming my abit KV8 Pro cannot.

right?

frostedflakes · Post by **frostedflakes** » Sat Jan 07, 2006 4:59 pm

Newark are the non-Turion64 mobiles, replacement for the old 130nm Newcastle and Clawhammer mobiles. They are part of the Athlon64 Mobile line, but use the same silicon as the Turions. Default voltage is 1.35V (the same as a 35w Turion) and they are available up to 4000+ (2.6GHz).

Generally they are a bit cheaper than a comparible Turion. Not sure whether your K8V Pro would support one or not. You might want to check the Turion compatible motherboard thread at the top of this forum, it has a site which lists boards known to be compatible w/Turion. If the board works with a Turion, chances are it'll work with Newark.

This is what I don't understand, what are you talking about??
Who calls it a Sempron?

~El~Jefe~ wrote:WHERE IS IT TO BUY !!!!!!!!!!!!!!!!!!!

Patience, my friend!
Newegg seems to have the 3000+, but you want a 3400+ which doesn't even have a retail code (yet), seems like its OEM only so far. Who cares. The problem is that it may be harder to find since it's OEM only. Ask your local dealer if they can get it, just give 'em the code: ADA3400AIK4BO

Hm, what do you mean in terms of "dealer" ? eh?

I wouldnt know what type of dealer could get stuff on request and not just say "whatever is in stock, um. duhhh.." any suggestions?

I would be satisfied for a year with that proc. 130nm is much hotter than 11 watts

~El~Jefe~ · Post by **~El~Jefe~** » Mon Jan 16, 2006 2:53 pm

Bah. looks like no one on earth knows where they sell this. (not the 3000, but the 3400+, the uber speed one)

frostedflakes · Post by **frostedflakes** » Mon Jan 16, 2006 9:03 pm

If you're really serious about getting a 3400+ Venice send me a PM. I can give you the contact info for a guy who is able to get hold of all kinds of AMD products. He's actually the one who got me my Turion64 right after they were released and months before any online stores were carrying them. He may be willing to order one for you. Although he would resell it at cost, you may end up paying slightly more than MSRP because his vendor charges more for small-quantity orders.

For anyone in Europe still interested in these CPU's, Komplett has them:

Doubt they give much extra performance over a Sempron 64, but they are at a great price.

~El~Jefe~ · Post by **~El~Jefe~** » Tue Jan 24, 2006 6:54 am

grr. im going to stab someone in the eye if I see another 2.0 ghz chip.

ever notice that just about every chip talked about is 2.0 ghz? whether it is dual core, opteron, 754 or 939 single core?

Bah. well, hopefully the 2.4 comes out in the 754 in some sort of retail /oem purchasable thing.

I have a question about this new cpu. I have a chance to buy one (box Venice E6 3000+) for 140$.
Now I'm using an Asus K8N mobo 1006 bios with 3000+ CG stepping CPU and Geil Value DC. kit 2*512MB DDR 400MHz memory.
I have read there are problems with the new versions, they are run the memory at only 333MHz if you have two double-sided (dual rank) module. (because of the AMD specifications)

Do you have experience with this new processor & K8N motherboard?
If I update my bios to the newest and change my cpu to venice, it's will be possible to run my memories at 400MHz?

~El~Jefe~ · Post by **~El~Jefe~** » Tue Jan 24, 2006 9:34 pm

er hm.

default vs forcing it to run is two different things.

the rumour is the default setting. I currently have 1 T timings on 1 gig chips, two of them on my kv8 pro Abit board. now it isnt supposed to run them that way with a clawhammer, but I can even reduce their timings if I want on medium speed ram, Centon, and still be stable. that's not supposed to work for me. shrugs.

I cannot undervolt my cpu though on this board. tragic.

anaqer · Post by **anaqer** » Wed Jan 25, 2006 7:52 am

I'm curious, what sort of OCs do people get out of these chips (mainly the 3000+) ? I've got one and no matter what I do, it won't really go any faster than 2300-2350MHz which is barely any better than what my Newcastle 2800+ did. So I'm wondering - is it the norm or did I just get a bad one?

~El~Jefe~ · Post by **~El~Jefe~** » Wed Jan 25, 2006 8:44 am

yeah that's not good. on a few sites I have seen 2.5+

Sounds like something is holding you back, I'd expect a bit more, but maybe you weren't that lucky. Lucky.

3 ghz on air would be the definition of lucky

I'm guessing it's the motherboard, but in an extremely quirky way. A Newcastle 2800+ ran (and still runs) at 9x250 with zero problems, but the Venice won't go over 236 FSB no matter what (240 FSB will boot but BSOD on loading Windows). Latest BIOS, extra voltage, lower multipliers, super relaxed memory timings - I can throw anything I have at it and it won't make a damn bit of difference. Quite frankly, I'm at my wit's end.

Mats · Post by **Mats** » Fri Jan 27, 2006 9:51 am

Well at least you've got a higher overclock! 10x236 is better than 9x250.
What mobo are you using? Can you get higher HTT in Windows with ClockGen?

Mats · Post by **Mats** » Fri Jan 27, 2006 10:11 am

~El~Jefe~ & frostedflakes: Could frostedflakes help you with getting that CPU? I guess you're talking about Vandi423 from the XS forums.

True, but not $60 better (which is how much the 'upgrade' did cost).

The board is an Asrock K8NF4G - it's a rather plain budget board, but even so many on the ocworkbench forums reached near (and even above) 300 HTT speeds... I'll have to give clockgen a whirl though.

frostedflakes · Post by **frostedflakes** » Fri Jan 27, 2006 11:42 am

Yup, it's Vandi423. But so far it doesn't look like he'll be able to get his hands on a 3400+ Venice.

I've read someone got higher HTT by keeping the integrated VGA enabled even though you're using a graphics card. Also have a look under the chip heatsinks and see what they're putting under those.

The LDT speed can be a limiting factor.
One difference between your old and new CPU is that the 2800+ runs at 4x HTT, and the 3000+ at 5x HTT. The board is made for 5x200 = 4x250 which you used for your old CPU (coincidence?). 5x236 = 1180 MHz, which is a lot. I don't know if

anaqer wrote:lower multipliers

includes HTT multiplier.
If you haven't tried, drop it to 3x and try again.

Mats · Post by **Mats** » Fri Jan 27, 2006 3:06 pm

No I was wrong, they both run at 4x200 according to AMD, but you'd better try it anyway.

There are now four S754 A64E. The fourth is this one, 3400+ BOX. Though it says it runs at 2000 MHz (another typo, like for the 3200+) and it got 256 kB L2 cache (one more typo?).

If there are two typos, then maybe ~El~Jefe~ is one step closer to find one.

~El~Jefe~ · Post by **~El~Jefe~** » Fri Jan 27, 2006 3:33 pm

*screeching brakes!*

hm. i see it has a box number!? it didnt have one a week ago !

What do you mean about typo's? What was mistyped?

That's a miscategorised Sempron 3400+ (notice the 'O3' instead of 'K4' in the OPN).

(Mats, I tried both with integrated and discrete graphics and HTT multipliers as low as 1x - sadly, no dice.)

show me some! off topic yes it is true!

Anyways, this 3400 venice 754 is one darn hard chip to find.

With this new 7800 GS comming out next week about, agp could have a long life. I mean that card could be a card for the next 2 years for myself, definitely so. my 9800 pro now works great on high settings for BF2 in big games. (I even have AA on x2!!!) 1152 x 864 is my settings with high detail. SO, my system doesnt really need a swap to 939 if I can both A, land this, B, land the 7800 GS (or the new x1700 agp for cheaper, based off of 580, not yet released, would be a nice all-in-wonder though)
