Anyone have a Week 51 A64?

[govtcheez75]

If anyone has one, how was your overclock? I've read too many conflicting threads about what's a good overclocker, and what aren't regarding steppings, and weeks.


I JUST received this 3200+ from ZZF yesterday, and am waiting on my Epox MoBo to put it in. The exact week code is: 0451FPGW.

I haven't read any posts stating that anyone had anything newer than a week 50 chip, and it does "generally" seem to get a little better, but some state that it's the letters that matter.

I have a 0451, and I have to say that I'm generally disappointed in it. I can only seem to get 2200 fully stable. I managed to get 2300 for a day on Prime95, restarted and came back and it was unstable for some reason. I can boot in with 2500, but no more than that. I'm very confused too since my temps are very low, I go from ~20 idle to ~33 tops with full load (Prime95/SuperPi) o/ced to 2200 with 1.6 Vcore. I'd say that weeks/steppings are meaningless measures. It just so happens that some people get lucky and others (like me) don't.

someone on another forum claimed similar results with this processor.

....I hope mine doesn't suck too.

 

[Ackbar]

I don't think that week to week variations are significant, I bet you have just as much chance of having a good one as anyone else. Give it a whirl.

 

[gobucks]

it could always be a chipset/bios issue. I had all sorts of stability problems and they were all because the bios sucked. Now my PC is rock solid with the new bios. Of course, I'm not exactly cranking up the CPU too much, but still my CPU doesn't seem to be breaking a sweat at all, and i plan to push it further.

I have the same mobo as you. I'm using the previous beta bios as the newest one didn't seem to be working very well. Which bios was giving you problems? The previous beta or the stock one?

I just got a week 51 3200 from monarch along with a K8N Neo2.

It doesn't OC for shit. Can't even get to windows overclocked.

Downclocked the memory too.

Running 3200VX with the booster.

set the divider to 8 and the fsb to 250 and the RAM does 2-2-2-10 1T 1:1 no problem.

downclock the RAM by 50% and try upping the FSB even 10 MHz and I get problems.

I am going to swap in a 3000 (not week 51) I have that hits 250 in my other board and we will see what happens.

Makes you wonder if they did *something* to limit clocks. Typically CPU production and yield just gets better the later date thus better clockers, not here.. seemed to peak at week 48 here. But that's not as strange as going from 2700Mhz on default core all the way down to ~2200Mhz.

Wonder if it's possible that they started experimenting with Strained Silicon.

 

[Painman]

Sorry to hear you guys are having such bad luck with week 51. Seems like Zebo might be right about 0448 being some kind of peak. I got an 0450TPGW and so far it seems to be a decent, not mind blowing OCer but I have a lot more work to do on it.

how much?

 

[govtcheez75]

I just pushed the week 51 chip onto my brother who won't be overclocking. I'm going to order one more new one, and see if I get a week 1/05' or newer.

....I'm trying to get a chip that will do at least 2.5-2.6 stably. I may just have to buy a used 3000+ instead.

 

[PClark99]

scratch my last comments. I switched the 3200 to my wifes machine. It is the same board but using OCZ 3700 EB instead of the VX.

I easily booted into Windows at 2500 at 1.45V core. I have to confirm stability, but I bet at that voltage or higher I will be good to go.

Now the $64,000 question is, I have this 3000 that I know does 250 fsb. I will try it in this machine.

If it doesn't work I will take the RAM from the other machine. if that doesn't fix it, then it has to be this board.

 

[PClark99]

Well,

slipped in the 3000, set the fsb to 250, RAM running 1:1 at 3.4V OCZ DDR booster. with 2-2-2-10 1T.


This board undervolts big time, I have to add a little voltage.

Its stable in Windows at 1.4V core actual.

I will bump it to 1.45-1.5V just to be safe.

Must be something about the memory controller on the 3200 chip that the RAM doesn't like maybe?

 

[Markfw]

My 3000+ and Neo2 from Monarch was stable at 2400 (sort of) but wouldn't finish superpi until I went down to 2295. Still having problems with F@H at 2250.

Lots Basically all I have so far for the new rig are the CPU, the K8N Neo4 Plat. and an XP90/Panaflo H1A that's clamped on to my Northwood for the time being. Only preliminary testing so far using stock HSF, Antec SL350 PSU with a spindly 16A +12v rail, single 512 Samsung original PC2700 CAS2 stick and a PCI Riva 128. I played around with 270x10 briefly, the chip will hit it, it booted into windows but I was at 1.675 Vcore when it did so. I wasn't about to play around at these speeds and voltages on the stock HSF for long, this was just a sneak peek at the chip's upper limits. The board seems to be rarin' to go, I tried 333 6x multi 3x HTT and she fired right up.

I'll wait until I have another compatible PSU and more RAM on hand at the very least to do any more testing, then I can do so without having to steal the Northy rig's guts. And I'll have much better power and cooling. Nonetheless... committing to that mid-high 1.6v territory on a Winnie to reach 2.7 makes me uneasy, I don't usually gank chips that hard. 2.5-2.6 on 10-12% overvolt might be what I finally shoot for.

I just got a week 51 from new egg.

0451PAW

My max comfortable overclock is 9*292 = 2628 on 1.522v 46% OC
idle = 31C max load = 44C Prime95 stable overnight
on an Epox 9NDA3J with a thermaltake A1838 cooler.

It is prime stable overnight at 9*300 with 1.546v, but load temps ~ 48C - 49C and that's a little hotter than I'd like until I find out how these things take heat. 50% OC :Q

Right now I have it at 9*282 at 1.471v and idle is 30C load is 39C 41% OC

 

[Jhatfie]

I just got a 0501 from Newegg. But it is a socket 754 DTR 3000+. Still, it is a pretty excellent overclocker for a clawhammer. Right now I've got it stable at 2.7ghz (300x9 : 9/10 memory divider) @ 1.65v on my DFI NF3 250GB. Not to shabby for $145.

 

[Idleuser]

Primestable over night but how long green man? Mines died at the 9th hour at 2.6ghz while at 2565mhz i am able to prime stable 24 hours... big differences being able to prime overnight and being able to prime for a full day.

 

[Jman13]

I have a 0451, and I've got it running at 9x256=2304 right now, but what's limiting the overclock is my RAM at the moment. The 133 divider on my 9nda3+ doesn't work above 245 FSB for some reason, so I'm running 166 divider (RAM at 209MHz). beyond that, it gets unstable after a while. At the current speed, runs Prime95 all day without errors and finishes SuperPi 32M in 32min 29sec. I booted into Windows above 2400 with this chip with the mem at 100, but it became unstable at 2446 (272 FSB). That was with stock voltage. I didn't bother to raise the voltage to 1.5 or so because I'm not going to bother going above 2.3GHz if I have to run my RAM that slow. I have a feeling with extra voltage, the chip will be stable at 2450 at least, perhaps 2500. Above that is probably sketchy.

 

[Jman13]

Hey Paul...you didn't go to high school in northeast Ohio did you? I went to school with a Paul Clark.

 

[PClark99]

Same name, different Paul, I went to perennial football power Rutgers!!!

 

[bersl2]

Sounds like I'm waiting a week or two more...

 

[PClark99]

Well I have had a little time to play around.


Seems like my K8N Neo2 did not like OCZ VX 3200 memory, especially when I try to hit 250 FSB at 1:1 with 1T timing.

So I dropped in some OCZ 3700 EB, and I got the week 51 3200 to 250X10 at 1.5V core actual.

Idle temps around 35C with a Swiftech mcx64V cooler.

I purchased this chip new last week from Monarch.

The markings on the chip are:

ADA3200DIKBI
CBBID 0451BPEW
1173667A50427

It games stable and thats what counts. If I run into any problems I will post them because problems seem to always crop up later.

 

[Amaroque]

I just recently installed a...

ADA3500DIK4BI
CBBID 0451DPBW
1174045A50080

Booted straight up to 2.6GHz w/o even any type of burn in. I installed it, and had it at 10*260 4x HT within the hour. I still haven't pushed it yet.

Prime95 has ran for over 24 hours straight w/o as much as a hiccup.
