Overclocking the Venice 3200+..

[Taejin]

I overclocked my venice 3200+ to 2.65ghz on stock voltage and 24 hours prime95 stable as well as SuperPI Mod 32M stable.

I was wondering what kind of overclocks other people were getting in order to see if juicing a little voltage to my processor would give me any significant gains.


For those that are wondering, I'm using a
DFI Lanparty UT Ultra D
OCZ Powerstream 520W
2x512 OCZ Value VX
Stock heatsink/fan
Cooler Master Stacker



CPU temps are 32-34 idle and 49-50 on load.

EDIT: I figured case might be important too.

My chip goes to 2.5GHz on stock voltage. Getting it to 2.6 with a slight bump in Vcore and Is currently priming at home to test stability.

 

[imported_g33k]

Maybe I didn't get a great chip like you, but I couldnt get to 2500mhz without bumping up vcore to 1.5 volts. I was able to get to 2.6ghz with 1.67 volts.

Specs are:

DFI Ultra D
2x512MB OCZ VX PC4000
Seasonic S12 500W
Zalman 7700cu
Lian-Li PC 60

oh, so 2.65 on stock is on the higher end? I was under the impression that it was average.. but I wasn't sure, thus the creation of this thread .

 

[imported_g33k]

Well from the info I've been getting, 2.65 volts is on the higher end. My chip is an LBBLE 0519. At stock voltage, I was able to reach 2450mhz. I had to dial up to 1.52 to reach 2500mhz and to reach 2600 mhz I had to go all the way up to 2.67 volts!

I'm not sure with 2.7Volts that I will have any longevity with this chip. I wonder if Venice can handle higher volts, than Winchesters?

 

[blckgrffn]

1.55 volts for the frequency in the sig. Kind of disapointed, but hey, 500 free mhz, not to shabby, eh? 1.55 is all my mobo allows, but it needs it all, I think with a little more I could hit 2.6 based on how long prime takes to bomb out, but is that really worth it? For the record, I have the really huge zalman 12cm cooler.

I have a week 12 CBBLE chip from newegg.

2.65ghz on 1.58volts. I can hit 2.7, but my vcore will be 1.61-1.62, so I backed down.

I can hit 2.5ghz on stock voltage, but I'm not sure how stable it really is. I was only doing 10-15min prime95 tests when trying to find the ceiling for the Venice. After 2.5, it seemed like a rough a .25 to .35 voltage bump for every 50mhz.

Taejin - Were you able to run your ram at 1T? I'm using OCZ gold vx (which is essentially the same ram as yours, minus the testing and the warranty to 3.5v's) and I can use it for a while before a hard reset. Putting it at 2T fixes everything.

Yeah, I run my ram at 1T. I didn't really want to go through the trouble of finding all the settings for my ram, so I actually have it on loose timings 2-3-3-8/all other options auto. my FSB is a 265 with a 5/6 divider (don't want to do the math just now).

As far as I've read on this board, people seem to say the timings dont matter *too* much, so I'm not really concerned. All I really wanted to do with this computer in terms of overclocking was to hit 2.6ghz on air.

With adequate cooling, what's the maximum safest voltage setting?

What does the warranty say?

 

[Taejin]

For what, the CPU? I'm just a college student. There's no way I'd push my CPU past 1.55v, period.

As for RAM, the guys over at dfi-street hit 3.4+V when they're dancing on the edge *i think*. I have my ram set comfortably at 3.0V.

One more question What DFI bios are you using? I'm using the official 3/10, and it doesn't seem to like 1T no matter what RAM I put in it. Your ram is running 220mhz at 2-3-3-8. I think I might put my ram at that setting. Its running 200 at 2-2-2-8 right now, but I'm not sure if your setting might be quicker (granted... its very marginal at this point)

 

[Yanagi]

granted mines a 3500+ But they're basicly the same anyway... My chips seems to be average. Priming @ 2.65Ghz still. No errors. VCore is set to 1.54. I dont intend to up my Vcore more so I just have to find the highest stable overclock from here. Also I dont want to turn my fans up but right now my CPU wont go over 46C which is still very fine imo.

I'm plenty happy with 2.65GHz from this chip. Tomorrow I'll try priming 2.7GHz and see what I get. It would be really sweet! FX Performace for 1/3 the price

exatly the same here lol....LBBLE 0516EPEW (newegg)

Hmm weird.
1) I have the 3/10 bios, I'm not using any modded BIOS from dfi-street.
2) I took off the RAM timings from my friend. But he had two mismatched sticks (didnt report as the same in CPU-Z) so he's got an RMA. Previously I was running at 2-2-2-7. However, memtest showed no errors, but I still got BSOD's when booting up. I figured this was bad, and I was honestly too lazy to get my own timings and tweak them, so I simply set it all to stock and 2-3-3-8.

:b Am I special or something? Maybe my de-magnetic personality messes with the hardware or something..heh.

Uh. I don't know .

Everyone says that for maximum CPU voltage w/ air cooling, it is STOCK VOLTAGE * 1.15.

So that's ~1.63V. I would never push my CPU like that though. I dont have the money to cover another expense, and I'd like my computer to last years and years. That's why I just did the highest overclock I could on stock voltage.

My Venice 3200+ is stable @ 2.6 GHz (1.55V) on everything (Prime95, SuperPI, Memtest, 3DMark 01/03/05) except UT2k4 :|

Since i play UT2k4 like every couple days, i've had to drop my OC to 2400 MHz, since i'm not willing to put more than 1.55V into my CPU.

 

[imported_g33k]

It seems venice likes vcore. You may get to 2500mhz on default vcore, but to get to 2600+ you are going to need to bump up vcore. OF course their are always exceptions. But I think that what I'm stating is the about the norm.

 

[Taejin]

[unwhippable]

my venice 3200+ (monarch.com) is stable at 275X10 in everything, prime95 stable overnight, superpi 32M stable, counter-strike stable... although my vcore had to be bumped up pretty high (look at my sig), with my HSF, the temps are nice so i'm keeping it at that vcore.

[blckgrffn]

I did some more checking, and basically with higher ambients, I am stuck with 2.4 at 1.47vcore. I was hitting 58C and then bombing Prime with ambients in the 80's... sigh...

I have just got a Venice 3200+ on stock (getting a Silent Boost soon), crappy 2x512 mb 3-3-3-8 ddr400 RAM ( I know, I know, once I have some money I'll get Geil or something) and 6800gt stock. All running stock voltage.

I have gone up to 2500 MHz (10x250, memory at 166 MHz, htt 4xfsb), when I hit a snag. Priming is very stable, sandra burn in is good, 3d mark 2001 is also OK. But 3d mark 2003 always bail out at the planes CPU test. Tried running the memory at 133 MHz at 2T with the same issue.

My question is:
Running the memory at 133 MHz, means that its effective running speed is (2500/2000)*133 = 166.25 (well below SPD) But do you think lowering the timing would help?say 3-4-4-8
Or do you think this is a limitation of the CPU at stock voltage?
I would have thought that memory timing wouldnt matter as I am running within SPD with a divider anyway...

Thanks

i have a lbble 0519 but it doesn't like voltage, right now i have it set to 1.35*1.10=1.485 (1.44 in readings from bios and mm5) 8 hour prime95 stable and superpi stable at 2600, venice's on air as well as other 90nm amd64 chips aren't really supposed to have more than 1.55 volts roughly
