markiemrboo Posted February 10, 2005 Posted February 10, 2005 I got a A64 3000+ CBBID 0451APBW. Just now read that the CBBID's are really bad overclockers *sigh* I'm reading 1.65v for 2.3ghz and it aint stable... Do you think maybe I could ebay it after testing it out and hope I get lucky the second time around? I don't want to sell it without testing it because, well, there's a slim chance it's faulty (may I remind you my luck isn't going to well lately) and also I really want to get this A64 setup and running to see if my new RAM is faulty or if it was just the NF2 being dodge. There'll be somewhere out there who doesn't overclock and just wants an A64 system, right? *cries* Quote Share this post Link to post Share on other sites More sharing options...
r_target Posted February 10, 2005 Posted February 10, 2005 Did you try dropping the RAM speed way low, just to eliminate it as a variable? Initially, the prevailing wisdom was that the later the week, the better the OC. But from what I've seen, every week of production has had some diamonds and some dogs. Also, I see the production week cited more than the actual stepping for A64's. Yours is a week 51 so it seems like it shouldn't be a total dud.

markiemrboo Posted February 10, 2005 Posted February 10, 2005 Well.. yeah I got sent the wrong board so I can't actually try it out yet. It's sitting on my desk staring at me.. and i'm sitting on my chair staring riiight back at it I have tried lots of stuff trying to get the RAM to run on my NF2 and it don't wanna work. I think the duds are probably the CBBID ones I've yet to see someone with a CBBID chip and a good overclock! I'll just have to keep my fingers crossed that mine is the exception, I guess... what actually is the CBBxx part about anyway? That is the stepping bit isn't it?

swifty11212 Posted February 10, 2005 Posted February 10, 2005 i dunno but i hope my 3200+ 64bit that should arrive here tomorrow isnt a bad one. i screwed up getting a non tccd corsair xms lol, i just hope my processor is not a dud.

r_target Posted February 10, 2005 Posted February 10, 2005 ... what actually is the CBBxx part about anyway? That is the stepping bit isn't it? 415999[/snapback] I believe that's the stepping code, but I'm not positive. But the word around the campfire is that the week is more crucial to OC possibilities than the stepping. Mine is CBBFD, and it's a week 37, which I thought was supposed to be not so good, but it's humming right along at 2.6 Ghz right now. There's always a big week/stepping discussion going on at Xtreme Systems, and those guys always put their CPU specs in their sigs, so just browsing over there you can get a general idea of what's going on.

markiemrboo Posted February 10, 2005 Posted February 10, 2005 Yeah I have been looking at xtremesystems Problem is: that's where I found out the CBBID is supposed to be the worst of them all I read about the earlier weeks failing Prime95 alot of the times. Seeing as yours is a week 37, does yours always fail Prime95, even at stock? Quote Share this post Link to post Share on other sites More sharing options...
r_target Posted February 10, 2005 Posted February 10, 2005 Mine does alright on Prime95. I ran all three tests for twelve hours each at 2.5 Ghz. My problem was that I couldn't get [email protected] stable until I started giving it more vcore. Wierd, huh? It's possible my motherboard factors into the equation too, but since this is the only A64 mobo I've ever had, I've got nothing to compare it to. EDIT: So wait a minute, has this chip even been in the mobo yet? Quote Share this post Link to post Share on other sites More sharing options...
markiemrboo Posted February 10, 2005 Posted February 10, 2005 Ah! The A64's all seem pretty random to me. You must be a lucky one I just found a [recent] thread on google saying that the CBBID's are supposed to clock better?!?! That half got my hopes up, but then I also found some dutch shop type review saying he'd got two CBBID's which were pretty crappy The chances are this BH-5 will only manage 250MHz max probly becauuuse it's two sticks of double sided 512MB (and the whole luck thing) So that'd work out at 2.3ghz ish with a 3000+, at 250MHz FSB/HTT thing. EDIT: No, they sent me a 754 board by accident :mad: .. stock mix up apparently Quote Share this post Link to post Share on other sites More sharing options...
r_target Posted February 10, 2005 Posted February 10, 2005 Oh, OK. I remember the 754 mixup, but I thought you'd have the new board by now. Anyway, I was a little bummed when I first saw the week of my CPU, and a couple people told me not to sweat the week so much and just see what the chip can do. They were right. I just did a little quick googling myself, and I don't think you have too much to worry about. Also, you can run a divider on that BH-5 and run it 2-2-2-5, max out the CPU and still get decent memory bandwidth. Quote Share this post Link to post Share on other sites More sharing options...
markiemrboo Posted February 10, 2005 Posted February 10, 2005 No, it took me a couple of days to get the whole mess sorted out and now I have to post that board back before they send out the new one.. I think. Well, I guess that's what they're waiting for. They've added it to my account orders but it's been in the "confirmed" state for the whole day, hasn't moved to picking or shipped or anything Cool beans! You're right about the divider, I was reading earlier about how the divider doesn't affect performance or anything like on the A-XP's and whatever Good idea! If did that on a 5:4 then 300MHz FSB would be 240MHz for the RAM? 300 x 9 = 2.7GHz ... ut oh! Quote Share this post Link to post Share on other sites More sharing options...

Besides with BH-5 timings you'll be in good shape at 220-240 HTT. In other words, maybe it's time to start cheering up. Think positively, clock excessively.

markiemrboo Posted February 10, 2005 Posted February 10, 2005 Think positively, clock excessively. lol I like that one! I'll have to do some testing at the highest I can get the BH-5 vs the highest I can get the CPU with a divider.. type thing That'll keep me busy and away from Uni work for a while I'll probably be back asking for help soon Might take another week if they're waiting to recieve the board back.
