Venice OCing thread!

[Frown66]

Does anyone reinstall windows after you?ve been tinkering with your BIOS / overclocking settings a lot? Mine ran fine for a while (2.7ghz, prime95 stable for 13+ hours, stopped it to play games), but now it randomly reboots 5-10 minutes into Windows. I?m thinking my windows install is all jacked up now. I know when I bumped it to 2.8, it said I had corrupted system files on bootup, but when I backed down to 2.7, I got back in fine. I wonder if the damage was already done to some system files when I bumped it to 2.8.

I'll most likely reinstall.

Where to buy the ABB cores?? Im building a new system soon. Sometime early June and Ive waited since October for my funds to build. I cant wait and afford the X2s, so Ive decide to get a Venice and be happy with at least 2.5ghz for a while until the dual cores come under 400 or so. Might be a while, but Im upgrading from a XP 1700 Palamino so itll be a huge jump anyway.

Where to buy the ABB cores??

I *think* they were mainly test / sample cores. Only people I've read about that have used these cores were review sites with early samples. Most of the Venice cores appear to be LBBLE (3200's, like mine) or CBBLE (3000's). Recalling this from memory, so good chance I'm off.

I'm CBB and I'm rock solid at 2.805 GHz.

I'm CBBLE and I think I have more room but my Memory is holding me back!

 

[brentpresley]

Yeah, at 295MHz, that might be your bottleneck. LOL!

 

[Nil Einne]

There are def 3000+ LBBLE and 3200+ CBBLEs. I haven't see anything to indicate one is more common to the other but it's possible since LBBLE are the better ocers so it's more likely they'll be in the higher speed chips

is there any difference between retail and oem? which one OCs better or they are the same?

Just the warranty and the retail HSF..

Only problem is, you can't get a retail 3000+ from newegg.. You can for the 3200+

yes both the same, OEM = no warrenty and no fan .. retial is everthing

 

[Snowice]

thanks guys. i knew they are they the same. sorry about the question... should have made it clearer. my concern is that if they OC the same. i dont know why i always have the impression that oem chips are better OCer, but i want the 3 yr warranty.

A retail chip for instance with the stepping of : CBBLE 0516 will overclock essentially the same as a OEM CBBLE 0516

It's just different packaging, and warranty.

 

[Snowice]

cool, that explains it.... thanks bjc!

Alright...finally. After having my Venice rig staring at me from my desk for a week, I finally have gotten it up and running, despite being unbelievably busy working. I haven't placed my Zalman on it yet, so I've yet to see my production/week code, but I was so eager to start overclocking it that I decided the stock HSF Monarch gave me would do for now. Rig is as follows...

AMD Athlon 64 3000+ Venice
DFI Nforce 4 Ultra-D (4/14/05 v3 BIOS)
2x512MB Mushkin C2 UTT (Brainpower)
Leadtek 6600 PCI-e
Enermax 460w 24pin PSU (33A 12v line)
60GB 7200RPM 8MB IDE Deathstar
120GB 7200RPM 8MB IDE Maxtor
Crappy case
Crappy opticals
Crappy airflow


(I'm waiting on my CM Cavalier to solve the third to last and last items)

Preliminary exploration....

Settings...well, I immediately set my LDT to 4x, and flashed to the 4/14/05 v3 BIOS.
Memory settings at 166 divider, 2-3-3-6, DRAM drive strength at 8, Command per clock enabled, dual channel enabled. Onboard SATA, ethernet, firewire, raid, all that crap, disabled. Who needs features?

Sandra seems to tell me that a TRAS of 6 on my memory (UTT) suits me best with this board. I tested 6, 8, and 10. Subjectively, 6 also feels slightly more responsive, but that's probably my imagination. I'll tighten my other timings later on (I know my UTT is good for 230FSB 2-2-2-10 @ 3.1v from my DFI NF3, even with weak DRAM Drive strength in retrospect, which is suppose to hinder UTT/BH-5/Vx overclocking)

Stock voltage (DFI undervolts to 1.38v according to BIOS, speedfan). Sitting at 250HTTx9 = 2250mhz not a single issue to speak of. Small FFT load of 45C after 30 minutes of priming, with an idle at 36C. I'll keep going with this HSF until I hit 45C idle. That's my comfort zone. Time to go OC some more.

2340mhz @ 1.38v, yum. LDT at 3x now to ensure stability. If I can breach 2.5 on default voltage, I'm going to be excited. I may hit the lucky 2.8 that I've been hoping for.

2430mhz @ 1.38v
I'm going to skip P95 and go do some gaming. Haven't gotten to game in a while.

Prime just ran great all night over night at 2.43, so that should be a sufficient burn in to continue with today's boost

Just as a side-note, CnQ doesn't appear to be working with my chip, even with the newest BIOS, which really sucks. Ah well.

2520mhz @ 1.41v (1.45v selected in BIOS, but this thing is starting to undervolt very heavily) and priming strong.

keep on increasing it by 5-10 mhz each day to "burn in" properly, and maybe by christmas you'll hit 2700 mhz. I guess your sources say that if you go any faster your chip will fry......spare us the 1 mhz updates and come back when you find the max, hopegully before christmas

Greetings all, first time poster, long time reader.

Recently got my A64 system up and running. I tried my hand at overclocking, and here are my results in the time I was able to spare tonight.

Athlon 64 3000+ Rev. E
ADA3000DAA4BP
LBBLE 0516 CPBW

260x9 > 2340Mhz @ 1.38v (1.40 in bios)
280x9 > 2520Mhz @ 1.42v (1.46 in bios)

LDT: 3x
RAM: 2.5-2-2-6, 166 Divider, Dual Channel, 2.6v

Same experience as Avalon stated with under volting. I took it as far as I could without any major voltage increase, according to the bios on my DFI Ultra-D the cpu temp was 28C using a Thermaltake Venus 12. Prime95 stable for 24 hours, feel more comfortable running at 2.34 on a 24/7 basis until I really feel I need the extra performance.

System:
Athlon 64 3000+ Rev. E @ 2.34Ghz
Thermaltake Venus 12
DFI Ultra-D nF4 (3/10 Bios)
1GB OCZ Value VX
ATI X800XL

 

[user1234]

can't understand why you people seem to be afraid to increase the voltage ? isn't that why you got a dfi board in the first place ? 1.6 Vcore is perfectly fine, I've had a winchester running like that for months. It's almost as if you're tryint to protect a crown jewel, worst case scenario it will die and you get another one (but that won't happen anytime soon as these CPUs can easily handle 1.6V). 2.34 Ghz is reall wimpy even for a winchester, why not go for 2.8 ?

 

[Painman]

Waah, waah, user grows impatient. user demands RESULTS, according to HIS specs and tolerances, and NOW!

Cool your jets, bub. Have a on us while you wait.

I'm sure this is just a beginning as I haven't pushed the system yet. I wan't to get more familiar with the bios before attempting more aggressive overclocks. For kicks I did manage to boot in Windows at 9x300 and failed at 9x310.

Fvck off. Your exaggeration just shows your immaturity. I'm not "burning it in". I have a life, unlike you, so I don't have time to do this all at once. Hopegully my max will be as good as the previews. Where's your chip?

2.7ghz @ 1.575v...big voltage jump needed.
Prime keeps dying within an hour...I've tried using a 2T command rate, raising my TRAS, and disabling CnQ, not that it was working to begin with. Still not helping. My BIOS says I'm idling at 40C at this temp. My load shouldn't be any higher than 55C, so I wouldn't think it was a heat issue...unless my system is misreporting. I'll have to throw on my Zalman and get this crappy little aluminum thing off.

Will finish up later tonight when I get back in.

*Edit*
Some like to see the process, so they get a better understanding of how it works. Unlike you, I actually try to be helpful.

 

[SergeC]

Well, I certainly appreciate it, Avalon. I'm getting my Venice in tomorrow, and reading things like this is thoroughly helpful (not to mention encouraging!)

 

[Avalon]

I hit a huge voltage curve after 2.53ghz, and can't really get anything stable above that. I'm only using 1.41v at that setting, and it primed for 6 hours fpu burn in just fine. Once I take a jump to 2.61ghz, I can throw 1.55v at it and not be stable. It's probably my motherboard.

 

[user1234]

but isn't your motherboard the dfi ultra-d ? I thought that was the best overclocking mobo. btw, are you sure it's not your memory ? to rule that out you can run it slower with a lower divider, such that it runs close to 200 mhz. Also please try increasing the vcore to 1.65V.

You know as well as I do that there can be duds out there, plus there are no guarantees. I'm positive it's not my memory, since I'm already running a 133 divider on it which puts it below 200mhz, and my timings have not yet been tightened (2-3-3-6). I'm not willing to run an air cooled CPU at 1.65v, thanks. It's either the motherboard (or memory controller, however you want to look at it) having a hard time keeping up with the high HTT, or my CPU is actually overheating and my temp sensors not reporting this. I'll find out if it's the latter when I slap on my Zalman. Other possibility is that my chip just simply hits a wall after 2.53 and requires exponential voltage increases, although I've never experienced anything that bad with any of the dozens of chips I've played with.

 

[Duvie]

Have you tried a 100 divider?? What divider are you running??? I have noticed in my recent testing that 200 divider works fine up to 2.44ghz (w/ default 1.4v) but withn that range I cannot hit 2.5ghz with 1.5v.....YOu better start steooing down the divider as you climb and dont be afreaid to be running 133 even if your ram wont be doing 400ddr at those HTT levels....

It was holding BJC back and I have seen it many times....forget what your ram says it will do....what vdimm have you been applying so far.....That wall is likely a memory issue....Every time I have seen someone have one like this they eventually got past was due to memory.....

 

[TrueWisdom]

Avalon--try dropping your timings to 3-4-4-8, and make sure it's at 2T. I haven't gotten to your speeds yet, but to get to 2.4 I had to crush my memory timings. Because the memory controller is on the die, making sure your RAM is low plays a much larger part in overclocking than normal.
