These Venice Core Type things

[alexander]

Hello, thinking of moving to a Venice core from my 3500+ as It takes up lots of power and runs fairly warm.

I am just wondering what these are:

ADA3500DIK4BI

ADA3400AEP4AX

ADA3500DEP4AW

ADA3000DEP4AW

ADA3800DEP4AW

ADA3000DIK4BI


How do I work out what is Venice and what isn't?


What sort of temperatures will I be seeing when Idle and at full load?

What sort of Power Consumption will it be against my current 3500+ Newcastle?


Thanks, Alex

Have a look at this, http://www.lostcircuits.com/cpu/amd_venice/

i woulld not upgrde from a 3500+, there is not much difference, deff not worth it IMHO

Hi, the speed isn't really a concern.

I aim for my PC to be as quiet as possible, this means that the PSU should be outputting as little as possible, this means that the fan will turn slower and so quieter.

The Heat thing is also related.

So I was just wondering what sort of percentage power it takes up to the Newcastle?

Thanks, Alex

[nvening]

it really is not much different

Hello, thinking of moving to a Venice core from my 3500+ as It takes up lots of power and runs fairly warm.

I am just wondering what these are:

None of those are Venices I'm afraid.

ADA3500DIK4BI

That's a S939 Winchester at 2.2GHz

ADA3400AEP4AX

Erm....that's a socket 754 Clawhammer with 512KB cache at 2.4GHz *I think*. The AX suggests that it's a Clawhammer with half its L2 cache disabled, it'd be AW if it was a Newcastle core.

ADA3500DEP4AW

Socket 939 Newcastle at 2.2GHz.

ADA3000DEP4AW

Socket 754 Newcastle at 2GHz.

ADA3800DEP4AW

Socket 939 Newcastle at 2.4GHz.

ADA3000DIK4BI

Socket 939 Winchester at 1.8GHz.

How do I work out what is Venice and what isn't?

Well, there are two things that tell you what an A64 is (basically). First, the number after the DEP/DIK bit, this denotes the amount of L2 cache- in your case it's 4 on all of them since they're all 512K cache chips.

1 = 64KB (No K8s have been made with 64KB AFAIK)
2 = 128KB
3 = 256KB
4 = 512KB
5 = 1024KB

Then the bit after it AW, AX, BI etc. is the actual core type. I don't know all of them but I think AW = Newcastle, AX = Clawhammer, BI = Winchester, BA = Palermo (Sempron), BN = San Diego, BO = Paris (Sempron), BP = Venice.

So, if I saw a code like DIK5BN I'd know it was a San Diego.

What sort of temperatures will I be seeing when Idle and at full load?

Depends on your cooling.

What sort of Power Consumption will it be against my current 3500+ Newcastle?

At equivalent speeds, between a half and 2/3rds of what a Newcastle does. That's only the CPU though, the rest of the system isn't affected obviously.

Rave, if you did all that off the top of your head, im personaly going to slap you for not getting out more, before buying you a pint

[nvening]

thats wat i was thinking, i fell bad for my pathetic posts (no comments please)

[Rave]

I did, I'm afraid to say, do it all off the top of my head. As for the getting out more though....I'm married, that's my excuse.

[alexander]

Hello, thanks for that.


I am going to buy either a Venice 3800+ or a San Diego 3700+.


Basically I want the coolest (in Temperature) and the one taht consumes the least power.

Which one should I choose?

[Rave]

There'll be sod all in it TBH, literally a couple of watts one way or the other.

[alexander]

So you would recommend the ******* in terms of performance/temperature?

I won't be overclocking


Thanks again, Alex

[Rave]

Well, I reckon that the product ratings are about right, the 3800 Venice should be a smidge faster than the 3700 in most apps. It'll also probably produce a tiny bit more heat thanks to its faster clockspeed, but I mean tiny- we're talking 2-3W, which translates to an extra1-2 degrees with any half decent cooling system.

Why won't you be overclocking out of interest? If you just want a chip that'll run at 2.4GHz, you'd be so unlucky if a 3000 Venice didn't manage that as long as you've got a decent NForce3 or 4 board. It's £150 or so cheaper than the 3700 or 3800; that's money you could spend on (for example) a Zalman Reserator or an upgrade to kick-arse graphics card.

Overclocking is not just for performance nutters. For the last three years I've always run a system which is within 80-90% of the manufacturer's top of the line product (CPU wise at least), and I've not spent more than £50 on a CPU in that time. Even now my 2.3GHz Athlon XP is realistically within 25% of a stock FX55 in nearly all real world benchmarks and it cost me £20 secondhand.

[alexander]

Hi, the reason I don't overclock is because I don't know how to.

I think it will increase my temperatures and so my noise (My PC is aiming to be silent)

I don't think that my system can be upgraded hugely:

6800GT 256mb with VF-700Cu
3500+ With Freezer 64
Dual Samsung Spinpoints (Suspended)
MSI Neo 2 Platinum



I know I can make small improvements but I'm quiet happy as it is, its just the CPU temps that are bothering me and the power bills.

If you were to buy a 3200 Venice, there's IMO a 99% chance that it'll run at 2.2GHz with stock volts, and a 90+% chance that it'll do 2.4GHz, also at stock volts. You can make sure that the rest of the system will cope by doing a quick overclocking check now. This will make sure that the motherboard and RAM can cope. There is a risk attached to this, but it's very very small- there's an absolutely tiny chance that you'll actually break some hardware, and a slightly greater but still very small chance that you'll corrupt your OS install. You can pretty much nullify that risk by backing up your data before you start. I stress that the risks are small, I wouldn't even think about them personally, but it'd be wrong of me to tell you to do this without warning you.

So, if you're happy with that, do the following. Go into the bios. Set the RAM to run at 166MHz instead of 200MHz as it should be now. Adjust the CPU multiplier from 11 to 9. Set the HT multiplier from 5x (or it might be 4x) to 3x. Then adjust the LDT (FSB) speed to 245MHz.

That will get the CPU running at pretty much stock speed, but the rest of the system would be running at the speeds they would need to be to overclock a 3200 Venice to 2.4GHz-ish. Run Prime95 torture test in Windows for a few hours to verify that all is stable. If it is, you're pretty much set. A 3200 Venice cost about £120 the last time I checked, and you'll probably be able to sell your current processor on for something close to that. The Venice will run cooler and use less power, and the whole upgrade will have cost you very little. You could just buy a 3800 Venice for the same result, but for the sake of a little experimenting you stand to save £100 or more.
