venice on ice 2850mhz 1.38v -40°C

Still No new from VENICE ? ? ?

[mcnbns]

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).

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.

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.

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.

holy !

EDIT: please dont post huge complex posts like that thx

Don't be so quick to judge, you haven't seen anything yet

hey all, im new around here...i have just made the switch from intel to amd and purchased a new system....BUT WAS COMPLETELY UNAWARE OF THE 4 DIMM ISSUE AMD CPUS HAVE. What an idiot.

i PURCHASED A DFI SLI DR MOBO WITH 4X512 OCZPC4000 VX.

I havent purchased a cpu yet thank god cuz i didnt know what i wanted.

Did i just waste my money OR can the venice core save me? Will it oc with 4 dimms, or should i try and return the memory?

Where can i get a venice 3500 or 3800+? I live in canada.

Im not a noob but this post sure sounds like I am , haha.

You will be able to use 4x512, but only at 2t

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 ?

[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:

"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."

, 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.

Yeah, but the problem is that im a web designer, and my current intel system just died on me...

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.

tee hee

oh ya hey guys no swearing on these forums i got in trouble already.....

the dutch guy a.p. versteeg has a San Diego that does 3300MHz at 1.45V,
cooled by a Vapochill LS.

Looks good to me

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

[mcnbns]

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.

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.
