The Venice OC DISCUSSION Thread

[alpha0ne]

Just resived my 3000+ venice. It's a 0520 EPMW, and right now I'm running with the stock cooler and stock voltage. So far I have been able to reach 2,9 GHz with stock voltage but then it bluescreened
I'll be testing it futher tonight, and hopefully I'll mount my Vapochill SE tomorrow

So after 4 venice CPUs, I have got a nice stepping...

Hmmmm I have a 3200 0520 BPMW that so far have only been able to get 2400 default Vcore (1.344 in CPU-Z) , still early days though

I have a week 15 3200+ Venice and it has no problem running 2.8Ghz but i would have to agree that it seems to have a weak memory controller. It doesn't like to run high memory speeds so i sold my TCCD.

Yes, week 15 seem to have a very weak mem controller. Didn't allow my BH-5 run with 2T timing @ over 245 2-2-2-5. Is there any BIOS can fix this problem ? ?

There are two things that can help you to solve this problem:

- Disable Bank Interleave
- Sell the processor

Good luck

My venice week 15 can run my Tccd at 290 and my single stick ch-5 at 260 1.5-2-2-5 with 3.4v
My tccd at a claw hammer cpu was able to run at 315 at 2.8 volt....but now with this venice i was able for 290 at 3.1 v and 2.5-3-3-5 (always memtest stable)

[higherøx]

Here with my week 15 I can run 300 FSB 1:1.

E aeeeee Higher!!!


Hi guys,

I was wondering how much voltage is safe to run 24/7 on a Venice 3200? 1.6v? 1.7v?

Thanks!!

AleX

[higherøx]

E ae Alex.. hehe.. blz? :***

I think 1.65v would be a safe bet! In the air I wouldn't go for more.

Good luck!

[ReelMonza]

I would stick to no more than 1.6V for every day usage.

[OverClocker_gr]

E ae Alex.. hehe.. blz? :***

Good luck!

Depending on cooling

If you have air cooling i think that 1.55 its ok
For water 1.65
And on dd 1.75

Have you tried to run tight timing @ 250 2-2-2-5 ? Really disappointed about my 3200 week 15, althought it has impressive OC result

Do you guy have any BIOS to fix the mem controller problem ? PLzz show me 1

So.. yes i tried 260 at 1/1 at 1.5-2-2-5

[vozbidder]

sry bro , i wanted to know about dual , not single stick

[OverClocker_gr]

I think that there will be no difference if the controler cant handle it...

btw with my tccd at 2-3-3-5 i am able to run at 255

[Leverpospade]

I had my vapo SE installede last nigth, but I had a lot of problems getting the 939-kit to fit. After 2 hours I managed to get it to fit, so it could keep an okay temp.

Right now I'm running around 5-10 C idle, but in load it sometimes jumpes up to around 35 C

But here is what I have been able to do so far:

Anyone know how to bring down the PWMIC temp, cause it's seams quite high..

My mobo won't clock over 350 FSB, so have anyone got suggestion to how i can get higher??

Hope you understand my bad english

[SNIPoR]

ok here what i have done ... i changed my 3500+ (CH) to 3500+ ( Venice )
and iam very happy with until i reached with it to 2.65Ghz @1.43V.
the problem is .. During Prime95 CPU Torture TEST to see the Stability .everything seems OK. ( no Errors for over 2 hours)..but when i reach 2.7Ghz Prime95 does not give me any errors..no.. instead the comp hangs without any warnings..

so i think my PSU is the Problem ..right? i have 18A in 12+ Rail.

help plz

[Absolute_0]

It could be, 18A on the +12V rail is kind of low, as i've said before, it's recommended to have 26 or more amps on the +12V rail for AMD64 Xtreme OCing. I have dual 18A rails and they kind of suck, instead of prime95 erroring i get voltage droops under load and reboots. A more powerful PSU would be a good idea.

Reboots or prime95 hanging is caused by low voltage, give it more and it should be fine... but again, i think the low voltage is associated with teh voltage drop under load, my voltage goes down by ~.016 under load, which doesn't sound like much but *perhaps* that's the difference between fully stable and not fully stable.

so what Psu do you recommand me to buy??
i need the Psu to be fully stabilty at very high overclocking.
thank you

[Absolute_0]

I'm not sure, antec550 and powerstream 520 are pretty popular. Can't go wrong with PC Power and Cooling or a high end Zippy though

[SNIPoR]

will antec550 do the job perfectly??

[TheMeatFrog]

Look my 3200 has a new friend I got it earlier today but about 15 mins in I had to step out. Should have some results later tonight!

[SNIPoR]

What PSU you use to get that high of Oc'ing??

[OverClocker_gr]

Your +12v rail must have more than 25amps for stable o/c

[SNIPoR]

can you guys tell me which is the Best PSU for high overclocking for around 170$ ??

and Btw iam running Q&C = Default, the 12+=11.84v and @ 2.65Ghz ,12+ = 11.56v Idle and 11.36v @ load then boom restart

[4rory]

I picked up the Ocz modstream 520watt yesterday it has 28amps on the 12volt and a 12volt peak of 40amps, so far so good, I haven't had chance to test it fully yet but yesterday I tried 1.75vcore in corecenter and it didn't shutdown. So mayne soon When the a/c is on max I'll try some higher vcore, does this board undervolt or what? If i set 1.60 in corecenter i get 1.52 in cpu-z whos right and where can i test with Multimeter?

I just noticed that Now with 1.6 in corecenter I get hihger vcores 1.55 now lol sweet so I can probably low it abit and still be stable, I had 18amps on my old psu looks like it really was a problem.

[SNIPoR]

i found Vantec VAN-520A.. it got 28A on 12+ rail , 52A on +5 Rail and 26A on 3.3V ,,,what do you think?

other than that they got Enermax 600 and 550 watts PSU's and thos is really bad on 12+ rail ,, i know that they got 2x12+ but i dont need it cause they carry out 18A on both of them.
