3800+ Venice Screenies (Post #1 = FAQ)

[DrJay]

but winnies still arent that bad if you dont mind losing 200-300MHz performance, better ondie, sse3 and higher IPC but cant wait!

?

why would a Venice have a Higher IPC then any other AMD 64?

My thoughts exactly. Geforce, where did you hear that. I dont think SSE3 support and optimizations = IPC.

[Ad Rock]

Okay ill think ill be getting rocks thrown at me but i really dotn see what the big deal is.
First, its already a 3800+, a 450mhz overclock (and thats only superpi 1mb stable) isnt anything to write home about. Hell if it stops at 2850mhz (he said it didnt finish a 2900, so thats less than 30 seconds of stability), a good 3000+ can already do that.

Then 3000mhz at -47? Sure he didnt throw 1.70volts at it but im not sure these will even TAKE 1.7v, theres always a threshold where upping the voltage actually does anything, and if the stock voltage is lower, then the upper voltage will follow.

I guess im gonna have to see what a 3000 or a 3200 can do cause a 18% overclock (that we dont know is stable) on air isnt really blowing my pants away.

I think the point of that last screenshot that he showed us was to let us know that the Venice core can run stable in the -'s. Seeing as how the Vcore is so low he has not pushed the chip yet, just simply showing us that it will run with the superlow temps.

So, phase change only got you 100mhz? or maybe you haven't finished pushing it...I hope

I don't see any stability?

The E revision chips have a redesigned memory controller and erreta fixes that increase the performance.
The erreta fixes usually increase performance in any application that needs raw CPU power, but the affect of erreta is really negligible. But apps with need for memory bandwidth and especially games will probably see a gain of a few % when comparing Venice and Winchester at the same speed.
Its the same story as it was when we went from NewCastles to Winchesters, there was a very little, but consistant increase in performance on the Winchester.

woooot!! can't wait for san diego on ice :banana4:

Right. Very little because they were optimizations, which is what you are speaking of. I'm not an expert in this field but to the best of my knowledge, to change the instructions per cycle, you'd need to alter the architecture of the cpu.

[TysonM]

is that like 24 hours stable? cuase it seems a bit low compared to 2.9 on stock air

24 hours??? Lol. We've all been jumping on him to check out phase change every few minutes, we certainly haven't given him 24 hours to play with!!!

I see that he can reach 3gig with lower volts than he needed on air...

-47c? I don't see no cold bug here!!!!

Things are looking gooooooooooooood...

S7e9h3n... THANK YOU!

Yeah, you're right. But its not optimizations, its errata fixes. Errata is basically a bug in the CPU, so when it gets fixed, performance increases by a small margin as the CPU doesn't have to deal with the consequences of these "bugs".
In the first post I wanted, but forgot to say "He (Geforce4ti4200) probably meant increased performance and not actually higher IPC".
errata fixes increase the efficiency of the chip, they do not increase the IPC of a chip.

Hello all,
Man it's been a long night with this Venice. ,,,, It's almost 4:00AM here and I need to get some sleep for work tomorrow. I know you all are wondering what's the deal with venice and sub zero....well here's the answer:

-47C on stock Mach2 Display
-31C from Type K Thermocouple mounted to the side of the IHS

Move over Winchesters, cause Venice has arrived......

No cold bug Now the only Q is how the mem controller tweaks do.

Thank you s7e9h3n for your efforts!

3 GHz @ 1.36 V

nice, test it more, we wanna see moore
and remember to test 4x256 MB RAM 1T and your other Venice

[[XC] leviathan18]

come on friday arrive soon plz so our friend s7e9h3n can play with that cpu and show to us how far can OC it with sub 0 temps (give the poor man a rest 4am and his awake)

that clock per clock advantage of the Venice should be true considered the new SOI process the venice has, i doudt it's because of the SSE3 support

[[XC] leviathan18]

venice has sSOI process? or that is just reserved for the fx 57?

[WiCKeD]

24 hours??? Lol. We've all been jumping on him to check out phase change every few minutes, we certainly haven't given him 24 hours to play with!!!

I'd settle for 10 minutes on Prime or maybe even a 3DMark run... I want to know what these things can actually run at.

[krille]

hey, what time is it over there in Happy Land?

I wanna know how long till WEEEK-END!!

Well your not gonna get 3D from him soon.... he only has a crappy PCI graphics card.

I think thats what I read.... Way toooooo much info in these threads.

[Snowman89]

is the venice gonna be cheaper or expensiver than the winchester?

[[XC] leviathan18]

yes he has a 9800 pro

[krille]

is the venice gonna be cheaper or expensiver than the winchester?

Most certainly the same MSRP from AMD. Then the retailer can of course gauge the price quite a bit, if he finds fit. Pretty soon, though, prices will be as relaxed as they're now on the winchies. All speculations though.

[Sentential]

Very very nice Glad AMD worked the bugs out

As am I... I just "inherited" 4 air conditioners...

I really don't see any negatives with 3 Ghz at only 1.36. Thats very impressive to me - even non stable - give the guy some time to post his results! A bit of patience. Thanks for your efforts s7e9h3n

BTW - my winnie is suprisingly robust as far as vcore is concerned. I accidently left it at 2.60 on 1.8vcore. Using water cooling. I was running F@H. I came back 8 hours later, and it was still running at a CPU temp of 64C - this was also putting 3.6v through my BH6. I mention this just to illustrate than my winnie isn't a fragile little flower, so I hope the Venice isn't either

[Levish]

good job!

holy ba jeebus

Well, someone had his FX-55 running for weeks with severe condensation problems - there was water all over (he realized this when he checked twice, but fortunatley had been using dielectric grease on the pins). The system got quite unstable at times, but the mobo and FX-55 survived. That's what I call robust.
