no news??? try benching on air or water if really low temps wont work :stick:

Hi yall, this is my first post.

That is some impressive stuff. My clawhammer doesn't scale well at all at default voltage. Have you all tried the new relece of CPU-Z? It didn't mention if it had venice RAM corrections...but you never know.

Looks like the venice mem controler is REALLY spectacular, I bet the FX is jelios :). By the way, alot of people are speculating that AMD put an over clocking bug in there on purpose to hinder over clockers. Using the logic of Fixed multipliers as proof that AMD does not like over clockers. The fact is, the reason that the norm A64's are locked is so that people don't get chips that companys sell low speed parts as high speed parts. Remember hearing about the 1 million XP cpu's that were getting marked. Personaly, I think it is an error with an absolute value sign in the boot up cycle. As a programer, sometimes we get a little crazy to aviod math errors like dividing by 0 and like wise by just some code trickery. What happens is things like the negitive temp bug. Lets say the cpu is running at a core of -70, well, the MB would see 70c and respond acourdinly. That might not be the exsact problem mind you...but I do think it is a bug and not an intentinal attemt to hinder enthusiests from over clocking their own chips.

I must agree with you that it isn't very likely that the bug was made on purpose, but I don't think that AMD willl rush to the drawing board niether. Because there like maybe 10000 people atmost that have the stuff to get thier CPU to minus XX degrees.

I hope that the San Diego's won't have this problem because I'm gonna buy 1 and probebly put it under YoupY's cascade.

Seems goods this Venice, but with CPU-Z 1.28 there are bugs too ? :cool:

This chip has been tossed around for what... 4 days and noone has bothered to test 4x512 1T yet?

Its the burning question we all have. :stick: :(
4x256 BH5 was tested and it wouldn't boot

[derubermensch1]

I can't wait to see how far back in bios revisions on the DFI this chip will boot from ; )

I think that air and water are more important cause there is no real use for running these under extremly low temps (-70+) cause u cant use them 24/7.

Most people run on air / water.

[chefnr1]

:)well i just have to by a 3500+ venice

[saaya]

wat is sSOI?
ive only heard of SOI (silicon on insulator) SS (strained silicon) and SSDOI (a combination)
winchester doesnt have SS so that theory doesnt work :)

i talked to amd on cebit, and yes, all their 90nm cpus are built on soi and use SS. at least thats what they told me.


The FX-55 is and always has been strained silicon-on-insulator or sSOI, AMD publicly declared that at launch :up:

As for the cold bug - there are a number of theories but I personally believe it has something to do with the thermal diode reporting incorrectly, not inherent limits of the chip - AMD changed the diode with Winchester, they changed it again with Venice AFAIK and since we haven't seen new BIOSes for the chips yet (they haven't been officially launched, go figure) it's quite possible this issue could be resolved for all Venice core CPUs.

I remain optimistic! :rehab:
hmmm good idear matt! maybe the new chips need an updated bios as well to get rid of the cold bug completely... could be possible as well...

but from what i heard the temp probe hasnt changed in venice, it only has been changed in winchester and rev E4 aka san diego, wich is why they both needed a new bios to boot while venice doesnt need an updated bios.


yeah i didn't think about that... hmmm, well its gotta be the diode, i wouldn't be surprised if this cold bug is an anti overclocking issue made by AMD. it would make sense becuase they designate the FX line as their enthusiest proc and conveniently(spell?) it has no cold bug... similarily as we all know its mult is unlocked
but if this where true if then logically there would be a specific temp in which the procs would stop working and all would have the same bug, not just some :shrug:

lol, funny theory, but no, i really really dont think amd tried to limit ocers by making their chips unstable or not bootable at low temps. if they did then they did a really bad job since many chips seem to still boot at -40°C or even colder...

and i dont think amd would change their cpus just because 0.01% of their cpus get supercooled and overclocked, wich helps them marketing and selling their cpus...


Those 256MB sticks might have had chips on both sides of the memory module
but are in fact single "banked" alot of people get confused between double banked and double sided DDR SDRAM...

To test the memory controller they will need to use 4x 512MB ram modules, these will be double banked.
there are also DS SB 512mb sticks, but very few.
pc ice said he will use 4 512mb sticks of tccd and see if they run at stock with 1t and how high he can get them :)

hey MsB, welcome to XtremeSystems :toast:


Kinda off topic... but I just want to say that Saaya has been doing a good job of posting this topic to other forums! I'm sure a lot of people in other forums that don't post on other forums are VERY interested in the happenings of the Venice and don't always know where to get the best info. :toast:
thx :)

many news sites i sent a link to the venice preview didnt want to post about it because they or their partner sites will have venice reviews ready soon and fear that less people will read the review if they already saw a preview :rolleyes:
so i thougt i will just bring the news to the people directly then :D


This chip has been tossed around for what... 4 days and noone has bothered to test 4x512 1T yet?

Its the burning question we all have. :stick: :(
pc ice hasnt picked up the chip from opp yet, and opp can get it to boot under his cascade...

welcome to XtremeSystems Gsus_Freak :toast:
and im sure amd likes ocers, if they wouldnt then they would not sell a chip like the fx with all multipliers unlocked, and they would have locked all multipliers on all a64s and not just the higher ones ;)


4x256 BH5 was tested and it wouldn't boot
this sounds more like a bios problem to me though, since bh5 only comes in 32mb/ic sizes wich means 4 256mb sticks bh5 are pretty much like 2 512mb sticks bh5... of course there are other differences, but whether its 4 256mb sticks or 2 512mb sticks, its still 32 memory chips to address either way... so kinda weird the one works but the other doesnt?


s7e9h3n: Did you test how high the FSB did go with 4x512 and 1T timing? cus im going to order 4x512 TwinMOS Speed Premium & A64 with Venice core soon, and would like to know.
please read some posts before you ask something, in every page of this thread this question has been asked at least once and at least been answered once as well :D

[metro.cl]

amd wouldnt block the procesors for -100°C people that have that equipment is like 0.000001% of the market and limting the procs. because of them would be expensive

that would be bad for marketing couse most of us come here and see pc ice, fugger, macci, opp, opb, etc... and go and try to buy the procesors and all we can buy to reach the same level of oc (thats insane but hope is the last thing you loose)

p.d. sorry for mi english it sucks :(

[Lidocaine]

I have been communicating with an AMD Technician over the past several weeks over various issues, and hopefully this will clear the air in regards to filling all 4 DIMMS and running 1T CMD rate.

I asked this:

Will the Venice and SanDiego CPU's resolve this
issue.........meaning will these cores allow all 4 DIMMS filled with
double-sided ram on s939 boards to default to DDR400 and 1T CMD Rate
instead of DDR333 and 2T like the Winchester/NewCastle/Clawhammers
currently do?

His reply was this:

As you have perceived, the Venice and San Diego cores will alleviate
this problem. AMD has revised and improved the memory controller
within the chip to eliminate the issue.

Hope this helps. If you have any other questions, please feel free to
contact me.

Regards,

Quit stressing..................it will work. :D

[LowRun]

Thanks Lidocaine, damn good news, my 4x512 sticks should be here in 2 days so i'm a happy camper :D

[SLaY3r07]

Thanks for the news Lidocaine :banana:

[saaya]

thx for the infos :)

hmmm in case the 4 512mb sticks DONT work with 1t on pc ice' rig, then this means either your amd guy misunderstood you and meant they will default to ddr400 2t and not ddr333 2t like they do know, OR the boards need a bios update to not force 4 512mb sticks to 333 or 400 2t, wich makes sence as well....

if we're lucky it will work with the current bios :D

[winston64]

is it me or has it been almost 6 hours since PC ICE's post :stick: :rolleyes:

[Fzero]

I CANT WAIT FOR THEM TO SHIP ON THE 4TH :p:

there is one thing that bothers me tho everyone says the cold bug is the chips fault me personally think it is a mb issue that a simple bios flash will fix like how every one has to flash there bios to be able to use the venice.

i just dont see why AMD would not work on this issue more other then pass it down to a nether core well hopefully they will get it all sorted by the time i get mine because i wouldnt mind putting it under a ps unit.

It's because there essentially is no demand for a cpu that functions sub-zero. Only a small (I mean real small) percentage of users put cpu's under phase-change. ;)

[mcnbns]

About the temp issue... everyone keeps saying only the E4 (San Diego) CPUs had an updated thermal thingy. The E3 (Venice) remains the same (a la Winchester cold bug).

Therefore, it is my hypothesis that AMD redid the temp problem for their E4 90nm stuff so that people will be able to phase change cool FX-57s for some bad ass overclocking. We poor losers that have to get Venice CPUs (E3) will be relegated to -90 C or higher temps. :) (I use -90 C because that is when Opp said the Venice stopped working under his cascade.)

Remember, AMD is far more concerned about enthusiasts than some other CPU companies. Being that the FX-57 is an enthusiast-oriented CPU, it is to AMD's benefit not to thermally cripple it.

[saaya]

from what i heard it didnt stop working at -90°C, it didnt work at -90°C!


so far we only got confirmation of it working at -40°C and not woking at-90°C afaik, somehwhere between that it stops working, but who knows where...

and yeah mcnbs, about the temp probe rework and the fx57 thats exactly what i think, they re-did the temp probe so their enthusiast cpu is ready to reach some nice numbers.

this sounds more like a bios problem to me though, since bh5 only comes in 32mb/ic sizes wich means 4 256mb sticks bh5 are pretty much like 2 512mb sticks bh5... of course there are other differences, but whether its 4 256mb sticks or 2 512mb sticks, its still 32 memory chips to address either way... so kinda weird the one works but the other doesnt?

But wouldn't signal quality decrease when it is split between 4 banks instead of 2 banks? If what you say is true, then we would be able to oc 4x256 to simliar frequencies reached with 2x512. Who knows, maybe we can and nobody has tested...but I'm pretty dern sure it would take extra voltage. Nonetheless, it could easily be a bios problem.

[saaya]

i dont know tbh, i have always been under the impression that the chipset pretty much treats 1 512mb stick like 2 256mb sticks in the same slot (unless its a dual channel memory configuration :P)

[redgoo]

Wow, amazing results. I'm really looking forward to the water results as well.

Only 7 more days... plus shipping :)

[metro.cl]

i dont know tbh, i have always been under the impression that the chipset pretty much treats 1 512mb stick like 2 256mb sticks in the same slot (unless its a dual channel memory configuration :P)


Thats exactly what it does, is a per channel thing, slot 1 & 2 together become 1 channel that is why you can run dual channel with 2x256mb and 1x512mb (2x256mb on the first channel = 512mb, slot 1 & 2, and 1x512mb en chann2l 2, 3rd slot)

[STEvil]

i dont know tbh, i have always been under the impression that the chipset pretty much treats 1 512mb stick like 2 256mb sticks in the same slot (unless its a dual channel memory configuration :P)

It depends how the traces are laid on the memory stick.

2x256 DS can have the traces to each side so its actually still only "1 bank" per stick or could be done so its "2 banks" per stick... the number of chips on each side doesnt mean much.

With 16 chips per stick you've got no choice.

[sandybeach]

The 940pin chipset supports well doesnt suport, but will run 4x512 at 1t command at ddr400. All the 940 ads really is an extra pin for ground termination and an extra few wait states If I remember so I can't see it being all that hard to adapt it to 939.. But then again for some strange reason maybe its impossible, lol.

Maybe its the 940pin's thick arse PCB that can help with this as it uses a 6layer the 939 on a 4 layer. maybe its a combo of design and low noise that can allow the 940 to do it. "confused"

the extra wait states are through the reg memory afaik, right?
it works pretty much like adding an extra cycle of latency, but with memory interleaving the performence impact is pretty small it seems, as the first 940 fx cpus with reg memory scores almost the same if not better than 939 unreg memory systems at the same settings.

and stevil, are there really ram makers that put 8 chips on a 256mb stick and wire it like its 2 banks? wth are they smoking? :lol:

i wonder what micron thougt as well though when they made this 256mb stick with 4 memory chips on one side i have here :stick:

bad news btw, pc ice hurt his back trying to lift his cascade (dont try that at home kids! :D) and he has probs going on with the testing it seems since his back hurts a lot.
and he said he has the water and air results on a raid array he has problems accessing now but will post the results asap.
lets all wish him to get well again soon :toast:

[sandybeach]

Ive got a few vicoden he can have if it helps testing? ;) lol

as for 940 yeah the wait states and so on don't seem to hurt performance at all. It was more the HT sped gain from 939 over 940 and that the newer chipset nf3-250 - nf4 where at the time all 939.

I would like to see an nf4 Tyan with a single 2.6ghz 252 opty at 2-2-2-5-1t and twekaed with a64 tweaker and then compared side by side an fx55+dfi nf4 at same settings ;)

cant wait for the results! :D

[S0nic]

is that prime stable?

many 3500+ clawhammers are able to do 2.8 on water with a bit more voltage prime stable, some can even do it on air..

[Cpt Twitchy]

I hope your back starts to feel better soon pc ice. Take it easy as your health is more important than some oc'ing although some may beg to differ.

stock volts + water @ 2.8Ghz = :slobber: Once you get better keep up the great work.

i dont think pc ice wasted the few days he could play with this cpu running prime to see how stable an oc was ;)

and this is the first time i hear that many clawhammers do 2.8ghz stable on water... i have seen SOME few, but its def not normal afaik.

and again, it did 2.8ghz stable for all benches with STOCK vcore, so im pretty sure speeds above 2.8ghz can be obtained prime stable with more vcore.

[bachus_anonym]

keep going, dave....

[bachus_anonym]

Dave... Did you have a chance to see what was the max 3D or SuperPI benchable for 3500+ with max voltage neccesary? Did upping voltage give any gains? Were the 4x512MB sticks all same brand-speed rating TCCD?

[situman]

odd so it didnt respond to higher volts under water cooling. Bummer, so its either stock volts or nothing.

[chunkylover77]

the tccd's were very close to being the same..i do beleve if i have 2 more 512's of the same stuff then it would have worked..or mabey just a little bio's fixing..

it seemed as far as voltage went the chip didnt want any more voltage...but i was playing it very safe as it was not my chip. :) i tried 1.6v and there was no difference..

the PI was 33s @ that speed no patch.

i would realy like to have a chip like that in my gamer..

Now that is what I wanted to hear. :D

[cadaveca]

woah..let me get this straight...no gains at all from voltage?

[bachus_anonym]

it seemed as far as voltage went the chip didnt want any more voltage...but i was playing it very safe as it was not my chip. :) i tried 1.6v and there was no difference..
that's exactly what I was affraid to hear :(

2.8GHz is not too bad but unfortunately, not great either :( there are many 3000+ Winnies that are benchable on good air/water around 2.8GHz...
also, SSE3 extensions are not really that usefull at this very moment, besides the fact that SuperPi could be run with a patch now :D

it might seem that if one has 2.8GHz 3000+ Winnie, then be very carefull and do not sell it before you actually get Venice and test it...

~$300 for 3500+ Venice vs ~$150-220 for 3000+/3200+ Winnie..... hmmm

EDIT: I know, I know... latest Winnies are crap... :D but I had those that already have great clocking Winnies...

thing is they dont seems liek they scale well with more voltage (:

[shuRe]

i hate to say it but i knew that everyone would be disapointed, they arnt that better than what we got atm.

Got any air results?

[Squid_Spit]

I sure hope they respond to voltage while 2.8ghz on water is good but not great, i wanna see 3ghz on water.

[AMDnewbie]

A little disappointed now but hope its just afew that behave this way

[gundamit]

every chip is different..im not taking any of these result's as a influence on the next venice chip..i bet the next one will love the super cold and more voltage.. and 2.8ghz on 1.4v is no bummer at all. I like you're attitude. Stay positive. Under the same circumstances I'm sure some members would be wondering why God hates them so much and talking to their local suicide prevention hotline workers about how they think they'll never reach 3ghz. :hehe:

Great stuff BTW. Keep it coming. I'm going to wait at least a month to let the dust settle from the general retail channel release, and then decide if I'm buying in. 2gig (4x512mb) 1T for EQ2 would be too tempting to pass on.

[JDizzle]

Oh, and I forgot to say....for those that are wondering if these cpu's scale with voltage: They do scale, and very well if I may add.

So the 3500+ doesn't scale and the 3800+ does according to what pc_ice and s7 have said.

[gundamit]

So the 3500+ doesn't scale and the 3800+ does according to what pc_ice and s7 have said. I think PC_Ice is also saying we shouldn't be drawing any conclusions froma couple CPUs. This is just a preview. Who knows how things will really play out. A good picture should start to emerge when the early adopters (and the guys who shown a lot of discipline passing on the on the Winnies and Clawcastles/NewHammers over the last few weeks) start posting their results.

aMEN.
what seems to be the temp threshold here? what are the chances OPP and pc_ice can swap cpus? I am planning on running one of these on my single stage, so scaling is really the issue for me personally. My winnie was only about 100mhz better on phase. it would be nice to just crank her up and get a 1ghz oc but I think those days are over. :(

[mcnbns]

I, for one, am not disappointed with these results at all. As PC Ice said, 2.8GHz AT STOCK VOLTAGE is nothing to complain about.

If I can get a 3000+ and run it at 2.8GHz under water cooling I will be happy, and it looks ilke I might be able to do just that.

Thanks for taking the time to test this stuff, PC Ice! :toast:

[situman]

True different cpus will react differently to volts. I remembered the old 3.0c SL6WU didnt respond to volts at all, while the 3.0c SL6WK responded nicely to more volts. So we will just have to wait and see.

[s0ck]

Really need some air results chaps so the rest of us can work out what kinda oc we can expect.

Same here. But what concerns me is the 4x512 ram stuff 'cos right now i'm facing 4x512 of TCCD (just landed) that i expect to play nice with a lil' Venice, so really hope this will be sorted one way or another.

i agree, these are the most important seeing as there are more air coolers out there than water and phase put together

If you have an XP90 equivalent or better water cooling won't help with an overclock much at all, so these results are just about as good as it gets.

Water cooling doesn't give you that much better temps than air, but it has a higher capacity for cooling (it can deal with more heat better).

[s0ck]

I'd disagree there...



Water cooling doesn't give you that much better temps than air, but it has a higher capacity for cooling (it can deal with more heat better).

Exactly my point... it makes it difficult to gauge the results, especially when water has such a massive cooling capacity in comparison with air, despite the temps being very similar.

[mcnbns]

What I mean is, in this case, since a good air cooled setup will be able to deal with this amount of heat that water doesn't have an unfair advantage.

In either case, these results are a lot more informative than we often see for CPUs that aren't even released yet.

[saaya]

I'd disagree there...

xp90 and xp120 and other heatsinks with a high cfm fan get very very close to watercooling, and only top notch good watercooling setups can get notably better temps in my expirience.

does anybody have any reservations about buying one of these venice chips and it might not work on phase change? i know i do. i been looking for a solution incase my winchester doesnt agree with the chilly1 phase change cooler that hes making soon, and well i know it wont reach -90c and -40c might be more reasonable but who says all venice chips work like this one. i guess we have to wait till they are released for some solid feed back on subzero compatibility, besides one chip.

Well.....so far it's two outta two that work with single stage. Both the 3800+ and the 3500+ didn't have a problem at sub zero. The coldest I could get the 3800+ was ~ -35C. Also, the 3800+ was able to run benches @ ~2.9G on a stock hsf:
http://img57.exs.cx/img57/5968/10x2909pv.jpg
Personally, I think that these cpu's do scale with voltage. It's just that the range of vcore is smaller that what we're used to. The 3800+ stopped responding to bumps in Vcore at around 1.65V.

[saaya]

you mean you couldnt get the temps to go lower than -35°C because the mach2 didnt get the cpu cooler, or do you mean the cpu crashed when you reached temps below -35°C? evap temps or cpu temps read by the internal diode?

hmmm did you play with the 3500+ on air or phase change steven?
did it respond to vcore? dave said the 3500+ didnt respond to vcore bumps AT ALL and he tried up to 1.6v :confused: maybe its a problem with his board? :confused:

[s7e9h3n]

Hey saaya,
All temps I noted were read on a uei dt200 from a thermocouple attached to the side of the cpu. The -35 was just the limit of the cooling, not the 3800+. I don't think my unmodded mach2 could have gone any lower with this cpu.
Nope, I never even considered testing the 3500+. I needed a break after the 3800+ and put my fx55 back. I actually had spent more time testing the 3800+ with the mach2 than I had with the fx55.
In no way am I questioning PC-Ice's results with the 3500+, but there probably is a problem with this board or something of that nature. I have yet to see a cpu which didn't respond at all to bumps in vcore. The Venice scaled as well as, if not better, a lot of cpu's I've seen. It's just that the way it scaled was a little different. It seemed as if bumping the 3800+'s Vcore didn't have a large affect on the cpu's temperature. I don't think I recall the cpu temp ever idling in the 40's, even @ 1.70 Vcore. Basically, the cpu just stopped responding OC-wise beyond ~1.65V.

Damn, that sux pc ice. Lets just hope it's just your Venice that doesn't like volts.

Could be that they're now using the "crappy" cores for s939 512kb cpu's, and the good ones for the 1mb cache mobiles (turion) on s754 that have a lower wattage rating (around 35w?). this is however just a theory...

i dont think so, even average winchester cpus are able to work at the frequencies and voltages of a turion, i dont think that the turion cpus are the best a64 silicon amd can make, i think the best is used for fx chips, then high end a64 chips and opterons and then they test wich of the remaining cpus works good with low volts and make them turions or mid to low end a64s...

hmmm im going to ask amd about this, it shouldnt be a big secret they wont tell us :D

hi raul, welcome to XtremeSystems :toast:

Could it be possible that Venice and San diego has some kind of overvoltage protection ?

[Ackbar]

Oh, and I forgot to say....for those that are wondering if these cpu's scale with voltage: They do scale, and very well if I may add. My 3800+ could take up to ~1.75-1.8V and didn't explode. But upping the Vcore didn't help beyond somewhere in the range of 1.65-1.7. Than again, you never know what a cascade could do with these Venices :)


more than stock vcore barely seems to do anything to this chip

As I said before, you can not just assume that CPUs scale with voltage. My Clawhammer gets to 2.6 with near stock voltage, but it is entirely unachievable to get to 2.7 at ANY voltage with air (XP-120). I also do not believe this is an "overvoltage protection" issue since on the 3500+ Clawhammers this phenomena has been seen on most CPUs. Since the Clawhammer is much older than the Venice, I think this implies that this is just a result of the CPU itself and not a new "feature".

Like mine winnie 3000+ i could run on stock and up to 1.8v vcore and when it was going at the best it run 2840mhz, but my 3500+ winnie just like stock and up to 1,6 over that it doesnt happen anything it run as best on water 2870mhz cold water..3500+ did on stock 1.4v 2800mhz right out of the box :)

[Jasonhk]

possible the San Diago somehere got to use was Stable to 2850 Mhz then just dies of doesnt scale well at all to more voltage.

Um......I'm not sure where I stated that there was an "overvoltage protection" "feature" on these cpu's. :confused: And, unless your clawhammer is able to get to 2.6 AT default vcore, then it would be considered scaling -albeit minor- if you acheive a higher clock with increased voltage.

Sorry, I wasn't answering you about the "overvoltage" but I quoted you kinda as to show that there are two sides to this story. Sorry for the confusion! :D

I'm able to get 2.6 at ~1.55V (default is 1.5V). So you're right, that 0.05 V helped. But no, nothing after that really did anything. Don't get me wrong, voltage helps, by no means am I able to use anything below 1.55V to get to 2.6 GHz. That's obviously not the point though, the point is that after a certain point, the the voltage to clock curve reaches a point where it is no longer well-behaved (ie. it blows up and becomes infinite for all intents).

[saaya]

here is a nice peek at the short preview/review oppainter wrote with the 3500+ to get you all excited :D

because what we had not mentioned so far is that venice is faster clock for clock than a winchester ;) :D


Specs:

MSI X800XT 520/560
OCZ 3700 2.5-4-4-8 @ 300

From anandtech's talk with AMD...

Much as we suspected, all of the power optimizations that went "into" Turion 64 are all transistor level optimizations. Basically, selecting transistors that provide better thermal and power characteristics at the expense of lower switching frequencies.

Top story there today... the talk with AMD. There is more to it than Turion.

[LowRun]

Hehe, this answers all the "Why should i need a Venice" threads and posts.

[terrace215]

True, all these folks thinking they are going to overclock Turion to 3GHz + are sadly mistaken. AMD has traded transistor speed for lower power.

The parts to overclock are the Venice/San Diego parts.

[terrace215]

That's a 1% improvement over Winchester in that benchmark... not exactly thrilling, but better than no improvement at all.

[Orthogonal]

terrace, I think it was also done on fewer volts too.

[s0ck]

That's a 1% improvement over Winchester in that benchmark... not exactly thrilling, but better than no improvement at all.

Exactly.
I don't like graphs like that 'zoomed in' they are misleading and at first glance, performance looks to be over 100% increase.

[LowRun]

I think that what OPP wanted to highlight is the fact that the Venice is spectacularly closing the gap with the FX53.

[p00 p0wer]

must have venice. it sucks my winnie doesn't like the cold

[_Eduard_]

In a graphicly limited benchmark.

GT1, which is the only test it will affect, is only worth 7% of the overall 03 score. ;)

just wanted to say that... to measure cpu performance please don't use 3dmark03 or 05, use 01 or pifast etc...

anyway this shows that even with 512kb cache less the venice makes up the speed in some way...

[saaya]

:slap: the cpus were all running at the same clockspeed!

Top story there today... the talk with AMD. There is more to it than Turion.

yeah yeah, i know, amd told me the same when i talked to them at cebit, but i dont really buy it... i dont think they have an independant line of cpu cores for their turion cpus...

[Orthogonal]

3Dmark 2003 doesn't interest me as much as 3Dmark2001 or SuperPI.

How does the performance differ in those benchmarks. I'm interested in performance gain with the same clocks and voltages on venice over winchester. 3Dmark2003 always seems to be rather CPU limited.

EDIT: I meant to add also, a 1% improvement is also very promising when run with the same paramaters. What else do you expect from AMD basically respinning the same chips with a few upgrades. 3Dmark03 obviously doesn't support SSE3, so the only thing that can attribute to the gain is the upgraded mem controller and the few misc bug fixes. That to me says a lot.

[Opteron96]

Damn this venice makes me go :banana:
I sure can use some more CPU power to fill the memory busses

[S0nic]

:slap: the cpus were all running at the same clockspeed!
I know that, but since the venice is faster than the winnie clock for clock I was wondering where the clawhammer 3500+ would fit in, is it slower than the winnie clock for clock?

IMHO those are both kick butt speeds. Like arguing over a s2000 or an rx8 :)

What is getting my goat now is that the FX can boot under a multi-cascade situation but the a64s are having problems. Quite puzzling. It has to be a BIOS glitch. It makes no since otherwise why a claw hammer and a newcsl core can go under heavy cascade, but the new 90nm stuff can't. Even the pres'hots' can go under cascade and the are SOI and SS. hmmmm. ARGGG. Would AMD even answer us if we asked? Like sayya said, us super overclockers are about .001% of the computer world. Does AMD or Intel really care if a chip doesn't boot when exposed to temps that would kill any living thing it touched? :? I just dont know

it is demanding when someone says, id like to see the graph start from 0, thats a demand, and then when they say is that too much to ask? well, from my personal expierience most ppl say that last part harshly when actually speaking anyways, when is opp's post gonna be up?!?!?!

Hey I dispose of $400 at the moment, do you think that would get me a 3800+ venice? because the newcastle is at $373 at newegg or only a 3500+ because of the initial price raise? :stick: im not much of an economist :hitself: :stick:

Could someone with a Venice run Prime95 benchmarks and post the results here (from results.txt or as screenie)? I'd like to find out, if AMD did something with SSE2. Together with the memory controller improvements this should be good for several % of increased performance.

hey, welcome to XtremeSystems :eleph:

the venice isnt out yet, only 2 people here have a venice :D
the xbitlabs article is already out, they have a load of interesting results :)
amd didnt speed up sse2... i think thats what you meant right?
amd improved the imc and enhanced the data prefetch logic.
according to xbitlabs they also increased the write combining buffers from 2 to 4
(i thougt that was done in winchester already? :confused: )

and they only mentioned amds stretched silicon now for the first time, but amd has been using it for their 130nm cpus already afaik :confused:

What I'm looking for is if AMD changed something in the decoders so that they can decode SSE(2) loads in a way, that the 2x64bit access µOps can be executed by two different units in the FPU, not only one as it seems to be the case since first K8 (see
http://mersenneforum.org/showthread.php?t=1072&highlight=bottleneck and all the cache benches with 128 bit accesses).

And about strained silicon: DSL is a further improvement. They had simple strained silicon at AMD for 130nm.

damn i see buying me this holy piece.
seems to do well under sub zero (hope will do ~-50°C) and this is rather interesting. my prometia has to be repaired and so my winchester on air suxx @ +50°C...will see what he does and then look if i get my nc 3500+ back and then this one - good plan -.-

Wow, awsome results, and I was just getting settled in with my winnie, LOL... Out with the old, in with the new... Great job guys..

[Gsus_Freak]

xbitlabs has a preview of the venice core as well. They show a break down of the +3800 and the +3500 for all the differnt cores; clawhammer, newcsl, winnys, and veince. I know someone was asking about a comarison of the differnt cores and there you have it...less than a 1% differnce. Like the thermal specs too. For a non-OCed chip, we are talking about some low wattge. In fact, thinking of building a server box on the venice, or sould I get a hyper threaded p4 (sacrelig I know, but every processor has its streghs and weeknesses).

Edit...wow never mind...the venice is kicking the newcsl's butt....go venice

[Gsus_Freak]

ok guys. I have been reading up on the termal diode for the FX chip. There is a different programable value to control the boot of the processor. It seems that you can only program this at the factory. What that means for us is that the cold temp bug is not a bug at all, it is a direct result of factory programing. However, all is not lost. After looking at the power diagram, the diode has a negitave logic design. In other words, power when there is a problem and no power when when everything is fine. This means that a value of the termal temp waring boot diode has to be a vaule of 0, X, or Z to enable boot up. The thermal variunce has to be that of 100moh. What that means is if we can impeed the thermal probe, or just disconected it (remove the pin), that means no more cold start but.

I will also look into reprograming the Diode. This will be hard since that has to be a trade secret and AMD will not relece such sensitve information cause haxers could do VERY bad things if they had that information (like cause your computer never to boot). On the other had, all the information I need is in the pin plot they have availible online. However, it will take me actualy getting a venice and a FX chip (or a winny) to actualy test my results. That wont be happaning any time soon. I will locate the Pin shortly, so you you want to impeed the pin I find and find out, that would be fun, but i warn you, I am not at fault if you screw it up and take out a ground or power pin.

Table 29. Thermal Diode Specifications
Symbol Parameter Units Min Typ Max Notes
I Sourcing Currents µA 5 500 1
TOffset Temperature Offset °C 0 52 2, 3, 4, 5

1. The sourcing current should always be used in forward bias.
2. The temperature offset is used to normalize the thermal diode measurement to reflect case temperature at the worst
case conditions for a part.
3. This diode offset supports temperature sensors using two sourcing currents only. Single sourcing current
implementations are not supported by AMD.
4. The temperature offset is unique for each processor and is programmed at the factory. The diode offset value is found
in the Thermtrip Status Register described in the BIOS and Kernel Developer’s Guide for the AMD Athlon™ 64 and
AMD Opteron™ Processors, order# 26094.
5. TOffset should be subtracted from the temperature sensor reading. If the temperature sensor has an ideality factor
different from 1.008, a small correction to this offset is required. Contact your temperature sensor vendor to determine
if additional correction is required.

[Gsus_Freak]

btw this is what I am looking into

3.6 Thermal Diode
The processor provides an on-die thermal diode with anode and cathode brought out to processor
pins. This diode can be read by an external temperature sensor to determine the processor’s
temperature. Refer to the AMD Athlon™ 64 939 Motherboard Design Guide, order# 30474, for
details on connecting the thermal diode.
3.7 THERMTRIP_L
The processor provides a hardware-enforced thermal protection mechanism. When the processor’s
die temperature exceeds a specified temperature, the processor is designed to stop its internal clocks
and assert the THERMTRIP_L output.
THERMTRIP_L assertion is only valid when PWROK is asserted and RESET_L is deasserted.
THERMTRIP_L assertion indicates the processor die temperature has exceeded normal operating
parameters. PWROK must be deasserted in response to a THERMTRIP_L assertion to enable proper
processor operation.
Once asserted THERMTRIP_L remains asserted until RESET_L is asserted.
If the processor’s die temperature still exceeds the thermal trip point when RESET_L is deasserted,
THERMTRIP_L will immediately be reasserted and the processor’s internal clocks stop.

[Gsus_Freak]

so in other words. If silly MB manufatues use ABS(thermal probe) and see -90C as 90C then they send thermtrip_L signal so stop the clock (precived at a lock up). So we have to stop the MB from sending this input when a large negitive temp is sent.

nooo not again :shrug:

why do üpeople keep using that site? i hope it finally dies off... those roadmaps are based on pure speculations and have been totally off over the last years...
they claimed amd would go for an fsb of 250mhz (or was it 266mhz?) in early 2004 or something...

please ignore that site! :D

Gsus_Freak there are two low temp bugs, the one related to the temp probe reading has ben fixed by some mobo makers already afaik (see kevins fx55 shows a temp of 3xx°C reading the temp probe) the OTHER low temp bug however is related to the imc afaik and the drive strength of the memory wich increases the lower the temp goes. :)

[Gsus_Freak]

darn, thought i was onto something. O well, not many of us own a casscade anyway :) none the less a multi casscade setup (you guys got some cash flowing man). Not farmilier with the acronim IMC related to proccesor interface. I have heard of it refered to as integral multiplexor channel for IO and such (like a decade ago on some motrola chips), but I dont think that is what you are talking about is it? Anyway, nice score anyway, keep up the good work.

'Cold bug' my ass. Fantastic clocks Dave! :toast:

Lets see it put some of that power to the ground now, so to speak. :)

[matt9669]

Then the secret is out!

For the record, apparently the 3800+ isn't bothered by the cold, while the 3500+ would boot at -40C but not -90C, doesn't seem to be related to the BIOS revision either :confused:

Also, the ~3.85GHz screenie is not benchable at present.

[sandybeach]

Whats 3.8ghz tho if we cant run 3d/2d apps at over 3.6ghz?

Come on Ice lets see some real world benches not that screen shot sh*t..

If you have it running enough to take that CPU-z and verifiy it you have enough time to run a 2d 1m or pifast benchmark..

enough of this Sreenshot crap!!!!

Just an FYI Gsus... the thermtrip_L signal is an output from the CPU, not an input. Other tidbit, it's function can be disabled.

Peace bro :D

Peace bro :D

ya your right. The output of thermtrip_L is a signal when 125C is reached. And when reset and thermtrip are active high signals then CPU goes into a halt state untill thermtrip is active low. Reset has to go to active low signal as well but gets reset by powc(or something like that, it checks Vdim and VDD and HTT links to make sure everything is ok).

[ZeroHero]

that's great, 3.86ghz :D what vcore whas it done on?
Then the venice will be really good for xtreme cooling too at least if many chips is like this.
It would be cool if the venice would do be the first AMD to take 4ghz. :banana:

Guys, give PC Ice a break. He'll post results when he has them. Not everyone can spend their entire life in front of a computer.

[Gsus_Freak]

it is crazy that the k8 is now getting as fast as net burt. With a shorter pipe and low latency ram, though, the k8 is a sure fire winner. I would like to see how fast that 3.8 can crank out number. Maybe it will be my new server box? Not gonna have 3.8 OP for awhile I bet. Only thing is you can't really multi-thread with a single venice. With the extra HTT interface disabled, it is imposible to dual chip them as well....sigh. Has anyone ever tryed to OC an OP? I wounder how good that would go. Basicly the same as an FX i would hope. Only thing I fear is that the Mem controler might not be as strong for OC'ing as the rest.

Anyway though, I envy you guys getting those chips so high. Never though I would see a .90nm k8 would do that, was thinking that the 45.nm stuff would. Anyway, hope to see some benchmarks soon enough. Hope your back is feeling better ice. Good luck hunting down the Low temp bug. It has been sugjested to me that by my Dad (he is an Electricl enginner) to have the chip running at a stable temp (in this case -40c) and gradualy lowering the temp. He said that on some of his old planes, they wouldn't be able to turn on the computer till it heated up. Electricity doesn't flow as well in cold, so maybe heating up the core and then droping the temps down will be a way to by pass this. Just a sugjestion, I don't even know if you have much control over your cascade. But if you do, you might want to try it out (though you might of already since you know around -90c it stop working).

[mcnbns]

People have overclocked Opterons before. Do a quick search and you'll see some results. The main problem is that most boards require registered/ECC RAM, and that stuff usually comes with higher latencies than regular stuff.

[Orthogonal]

Electricity doesn't flow as well in cold, so maybe heating up the core and then droping the temps down will be a way to by pass this.
Actually, the colder it is the better electricity moves because there is less resistance. The reason the cold can sometimes have negative effects is because the electricity moves TOO well, and it can cause raise conditions and have signals get to places faster than they were designed too. :eek:

[sandybeach]

Remember this Guys you can tune a cascade just like stacking pelts.

So the base temp is low as hell but can't remove any real heat..

a 3.8ghz 90nm cpu at 1.75v =200w+ load easy sure, but Idle for a 2sec SShot maybe, maybe 100w 50% of the load wattage.

Also a -130c 3 stages oil will clog in seconds and drop evap temps as the load is put on the evap thus casuing the 3rd stage to fail..

So this isn't just a suicide SreenShot Its something thats just way out of stable lanes.

A 1m at 3.6ghz is 100x's as impressive..

Thats what makes Opp so great as when you see his max cpu clocks they are displayed in his result brower on the 3dmark orb.. Unreal Cpu clocks/Unreal Gpu clocks all done in sync as a Team always..

Now don't try to say Im flaming him as a person, as he's a great, great Cooling,overclocking, and tweaker we just really need to end these SreenShots that the max benchable speed is hundreds of MHZ less in real world app's..

There Is just no point..

Im happy he showed the world there is no Cold Bug as for that I praise him, but for the SShots "yes I will keep mentioning these" please put an end to it.. Its pointless. :)

NCIX.com is a good place to pre-order Venice.

Also, I thought it was a BIOS issue that 4x512MB can't be run at 1T with Venice yet. The CPU's mem controller is capable, but mobos aren't up to par. Wait for DFI to release a BIOS update before getting too upset.

[AMDfan]

:( No VENICE yet ? :( :slobber:

[trakslacker]

^ no. You'll know when it hits.

[bugeyes]

dsumanik ...
Getting 4x double banked dimms running beyond 200MHz is going to be tricky even for Venice, to ask if your VX will be compatable with a centain mother board and with an unavailable cpu is beyond prediction.

[dsumanik]

Well should i just return 1 gig of the memory then?

I guess i could always buy it later once we find out whats going on with the 4 dimm situation?

Its too bad i cant get my hands on a venice...id be willing to be a test mule and find out once and for all. I am sure there has to be some others out there who want this exact config im running....

[dsumanik]

Looks like i found the answer for myself:

From xbitlabs review (http://www.xbitlabs.com/articles/cpu/display/athlon64-venice_3.html):

"Athlon 64 processors based on Venice can work with four single-side DDR400 SDRAM modules without any limitations, and if there are double-side DDR400 SDRAM DIMMs installed, they can work at 400MHz with 2T timing."

:banana::banana::banana::banana:, looks like im going to be using 1 gig. Pc4000 VX is double sided im pretty sure.

[bugeyes]

My point is don't assume compatibility.... If you can't get 2 gigs of VX ram to work at your desired frequency/latency.... then sell the spare gig ;)
You just can't predict configuration compatibility with new hardware, wait for the early adopters to finish their beta testing.

[chunkylover77]

dsumanki I have a great idea. Send me those sticks of ram and I can test if it works for ya. I'll send em back I promise.

i need a workstation up and running asap, every day is costing me money.so im in a hurry and unfortuntely at a hardware transition phase in the amd universe and i have money but no clue how to spend it. Im not worthy....

i used to have a
2.6@3.6 ghz 478
ic7 max3...which im sure is the culprit
gig corsair pro pc4000

i crappin my drawers cuz i had a bunch of recent work on a raid 0 array that i hope i can recover on the dfi.

i dont know if i should sell or hang on to the pc4000 I bet it overclocks nice at higher voltage...

on a side note, i have a "vtt fix" chip for an ic7 max3 i never got around to installing if anyone needs one out there. It offsets the improper vtt tracking above 2.8vdimm.

anyone who wants to have my ram ill trade for another evga 6800gt so im sli capable.

Nice... why is everyone hanging around 1.4v~ though, aren't they scaling with volts?

Why don't some Pentium 4s like volts? It doesn't really matter, because they scale pretty well at low voltage, just like Venice seems to be doing.

[Wayway]

nice overclocks do u think the fx-55 will still be good enough until the fx-57 comes out and will it be worth the upgrade too.

[s7e9h3n]

Looks like i found the answer for myself:

From xbitlabs review (http://www.xbitlabs.com/articles/cpu/display/athlon64-venice_3.html):

"Athlon 64 processors based on Venice can work with four single-side DDR400 SDRAM modules without any limitations, and if there are double-side DDR400 SDRAM DIMMs installed, they can work at 400MHz with 2T timing."

:banana::banana::banana::banana:, looks like im going to be using 1 gig. Pc4000 VX is double sided im pretty sure.
Ummm, didn't I just say this?? :)

[mcnbns]

I would say tentatively, yes, assuming you have to have the top-of-the-line CPU and you have the money.

Right now we're all pulling these answers out of our behinds, because we haven't seen any FX-57 results.

[terrace215]

Ummm, didn't I just say this?? :)

No, you said 4 DIMMs means 2T, but that's not the case if the DIMMs are single-sided. :)

This is my :banana: SanDiego 4000+ on almost stock voltage :D 3300MHz and still plenty of room to play, tomorrow I will try to go as high as possible with more Vcore and other memory.

omg impressive, how many cost? and where do you bought it?

cost? nothing> direct from AMD :D

[winston64]

hmmm, how come the CPU-Z recognizes San Diego and not Venice :stick:

By the way what cooling are u using there :confused:

waww.... and cooling? MachII? i wanna see results on air :(

[Cpt Twitchy]

It says San Diego because in has 1024kb of L2 cache which makes it a San Diego while a Venice only was 512kb of L2 cache

On cooling I'm guessing he is using his Mach 2 which is in his sig.

why amd dont send me an fx57 ?????

[winston64]

why amd dont send me an fx57 ?????

for the same reason that they dont send you two FX-57s :slap:

:rofl:

nope, a Vapochill LS ;)

How does San Diego compare to Clawhammer (clock for clock/ipc wise)?

Newcastle -> Venice was a very big increase (where the biggest was the move to Winchester and 90nm), so following the same logic, shouldn't the new San Diego core show at least a few percent performance increase vs a Clawhammer (both clocked the same of course)?

Thoses Venices don't want to hit the streets or what ? :confused: :slobber:
still can't find them nowhere :(

AMD FAN,
I can see your eagerness to lay your hand on Venice. Check this thread and ask the guy where is the local retail that have it in stock. http://xtremesystems.org/forums/showthread.php?p=804819&posted=1#post804819

Thank you for your kindness, I have asked the guy for his local store address or phone number, but I din't get any reponse yet :( I want it and I want it now :mad: :slobber: :slobber: :slobber: :banana: :banana:

I want it too, I'm waiting for Venice to switch to s939 pci-e.

Relax and be careful. Don't go and send money to any phony place claiming to have venice. Be patient and I beleive the CPU will be everywhere by April 21st during AMD launch of Dual Core.

Thanks ! I will keep it in mine ! :)

should be faster, like 3% on average, and maybe up to 10% faster in sse3 apps at the same clockspeed :slobber:

[kamaleon]

dualcores are launched this month also?? lots of new cpus to choose from.... if only i had the $$ got to settle for a 3000+ or 3200+ venice.

edit: by the way in sor of new... been readign for a while and just did my first post... nice site, lots of info. :clap:

[J-Pak]

Oh god the Venice comes in and just blows away the winnie :D

[ZhaoYun]

I definitely want one. :slobber:

hi guys - so what is the final word on cold bug for venice? would an R507 modded prommy definiltey cause the cold bug? if so, is there anything I can do to stop temperatures going THAT low?
