michaelzhao Posted June 20, 2006 Posted June 20, 2006 Exactly what the title says. With AMD planning huge price drops on the X2's, I'm wondering what X2's overclock well? What X2 Steppings am I looking for? Also, I do not want to buy a 3800 or 4200 due to the lack of the larger L2 cache. Just this.... pretty simple question I guess... so... uhh... yeah...

ronin688 Posted June 20, 2006 Posted June 20, 2006 Well I can only speak for myself, but I like the OC range of my 3800 X2. I run a daily OC at 2.4Ghz which I know isn't that high, but it's running a 20% overclock at 1.30v which is at the bottom for recommended vcore (1.30-1.35 is AMD spec). I was able to go up to 2.7Ghz at 1.35v and my temps were almost the same as stock due to the small vcore increase. I've only got stock cooling, but I idle around 30-33C and load about 40-45C. I'm sure with good cooling you'd be able to push it much more. I'm happy at 2.4Ghz for day to day and I push it up to 2.7Ghz on occasion for some benchmarking. I don't see much real world performance increase above 2.4 honestly. I'd recommend the X2 series, very happy with mine so far. Like any other CPU it's pretty dependent on stepping. I've seen people having trouble getting over 2.2-2.4, but that's true of any CPU you decide to go with. Share this post Link to post Share on other sites More sharing options...
arklab Posted June 20, 2006 Posted June 20, 2006 Check the Opty threads - I think theres one just for 165's, too. From what I've read there are a few specific weeks that many think OC much better than others. That said, the biggest factor seems to be "Luck-of-the-Draw", just like it's always been with almost every CPU from both AMD and Intel. I once ordered a complete computer from Dell just to get a perticular stepping and week of a Northwood 2.4G chip. Someone had discovered that this chip could do something like 3.6, so I just had to get this "magic chip". I think he was the first to lable a CPU as a "OMG" chip. Yea, mine was OK, but no "OMG" (LOL). And there was a time that the Opty's were priced LESS than the same X2's were. Great idea then, maybe less so now. Some thing to always consider (unless this is just your hobby) - How much is building this rig with very high-end components going to COST? Now, how much is just buying a PC with a chip that is guaranteed to run that fast (or even faster) going to COST? When I've done that calculation, I don't even want to think about how many times I bragged just a little less! Still I had a lot of fun. And it still made little sense (and less cents). Edit: ... what was the question? I seem to have forgotten... Share this post Link to post Share on other sites More sharing options...
michaelzhao Posted June 20, 2006 Posted June 20, 2006 Yeah... I'm reading your post and I'm like... WTF!?!? Basically the question I want answered is what X2 steppings and editions overclock well? I only want a Toledo core because of the larger L2 cache over the Manchesters... I also want to know if any of the X2 steppings match the 165 in terms of overclockability. The reason I want to get an X2 maybe is because of the huge price drop that is anticipated... Share this post Link to post Share on other sites More sharing options...
THunDA Posted June 20, 2006 Posted June 20, 2006 I also want to know if any of the X2 steppings match the 165 in terms of overclockability. IMO.. NO ! I know you said you dont want the 3800 because it lacks the 1mb cache.. But honestly they clock great if you get a good one (close to an opty) and at those high speeds you will never notice the difference without the cache unless your into benching alot.

Guest burningrave101 Posted June 20, 2006 Posted June 20, 2006 Also, I do not want to buy a 3800 or 4200 due to the lack of the larger L2 cache. Well you'll have to deal with it because AMD already discontinued the 1MB cache X2 processors. If you'll go and look for the 4000, 4400, 4800, you will see there aren't any. I suggest going with the the X2 3800+ if you want an X2. Same thing if you're going to build an AM2 rig. It will offer the best price/performance ratio.

cuoficr Posted June 20, 2006 Posted June 20, 2006 don't mean to contradict but.... Linkage = 2x1MB L2 Cache X2's still available at Newegg.com, get em while u can Share this post Link to post Share on other sites More sharing options...

tasr Posted June 20, 2006 Posted June 20, 2006 What X2 processors overclock well? I’m running a A64 x2 4400+ solid at 2.7Ghz 1.350v@113% = 1.50v Vcore (roughly) with the temps at 27ºC idle and 45ºC load on air. I’m dual core prime stable for over 12 hours. So in my opinion this is well. I had it as high 2.75Ghz with a slight increase in volts but the temp rose to 55ºC. This also failed prime just over 7hr and I’m definitely about stability. I’m comfortable at my current clock settings. I may do some more tweaking to see if I can prime stable for 8hr+ at 2.75Ghz. I don’t think I’ll shoot for more than this, because my eye is on an Opty 165 and a Expert motherboard by the end of Summer. Just hope the Chief Financial Officer approves it. Check my signature (Main Rig) for my ODBC post. My stepping is listed there. Any that match the overclockability of the Optys? None, that I’ve seen. Of course that doesn’t mean there's not one that may, just I’ve never seen one. Search the Overclocking Database (OCDB). º¿º Share this post Link to post Share on other sites More sharing options...
Dave_Sz Posted June 23, 2006 Posted June 23, 2006 the newer x2 3800 seem to be hitting 2.7-3.0+ghz. That's why I'll be picking up a few when the huge price cuts come. Share this post Link to post Share on other sites More sharing options...
Guest Kobalt Posted June 23, 2006 Posted June 23, 2006 We have yet to see what the 'huge price cut' will be. Right now, you can get a OEM opty 165 from monarch for around $270 with coupon they list in their forums. I also think that if there is a *huge* price cut, the they will do it also for the opteron lines, or maybe they will just not offer the lower 165/170 models.

Dave_Sz Posted June 23, 2006 Posted June 23, 2006 just so you know, the 2x1mb cache chips will were not announced as getting price cuts. Plus, we saw what the prices will be. 3800 $160, 4200 $220, 4600 $300. So... Share this post Link to post Share on other sites More sharing options...
