It is cheaper to get used or refurbished Tualatin ready MoBo or Slot-T + Cu_Mine ready slot1 BX board from eBay ... What's the problem with him using a Slot-T on the motherboard he's got? looks like his board is PPGA only (his voltage regulators can not go lower than 1,8Vcore & only Powerleaps slotket has onboard independent voltage regulator, which tooks current from +12V source, thats why ..= (but these days is stupid to throw money for that, having so much Cu_mine boards for cheap around ...) .. You can almost always get a new motherboard for the cost of a powerleap, regardless of which upgrade type it is. But, without finding his original message, I could swear he said he had checked and his motherboard supported the lower voltages, and that was pa= rt of his confusion as to why they did not officially list it as coppermine compatible. maybe would be good to check that if his mobo can go lower than that with some spare/friends slotket+Cu_mine Cpu ... I would think that his plugging a 733 coppermine in and it working and=20 being reported as a 550E would be a reasonable test. Whether his voltage regulators can handle the current draw of a tualatin = is another matter. On that score, I blew the regulator FET on an original issue BH6 with a 1= =2E3=20 OC'd to 1.46, although that was partly because I let the ambient=20 temperature get away from me (Board since repaired but back to the P-III = 750 OC'd to 930). I also lost a chaintech, VIA chipset, using the exact=20 same tualatin, this time overclocked to 1.5. I haven't tried repairing th= at=20 board yet so I am not 100% sure it's the regulator FETs but that would be= =20 my guess. The FET on the BH6 opened but the chaintech is a dead short, so the sympt= om=20 is not precisely the same. Two other old boards, one a mATX Asus P2B-VM BX chipset and the other a=20 chaintech 815, are running reliably with tualatins at slightly lower=20 speeds, both about 1.35 gig. Although the chaintech blew the bookcase's=20 200W PSU, again due to heat because of the case's lousy ventilation, to=20 which I have since hacked in a 90mm fan, and poor PSU airflow. (here I have a spare semi-dead ms6163pro w/o blue sticker I partially repaired & looking the chips on it it should=C2=B4t work with Cu_mines= , but it posts and goes as low as 1,65 with Vcore for example, so you can no= t be always 100% sure w/o trying...) -- Regards, SPAJKY =C2=AE & visit my site @ http://www.spajky.vze.com "Tualatin OC-ed / BX-Slot1 / inaudible setup= !"

"Q: How do I know that my motherboard could support the lower voltages that Tualatin needs ? A: Check the PWM IC (Power IC) number from your motherboard. According to the number stamped on the IC , we could check the voltage range for you. The PWM IC is usually located nearby SLOT 1, capacitors and inductors. The PWM IC has about 20~28 pins. Most of slot 1 motherboards could support lower voltages at 1.3V except minorities VRM 8.1 older boards( VRM 8.1 voltage range is 1.8V~3.5V, VRM 8.2 for 1.3V~3.5V, VRM 8.2 for 1.3V~3.5V, VRM 8.4 for 1.3V~2.05V). " Hadn`t had a chance to read too deeply but it looks like I dont need the expensive IWill adaptors that regulate voltage,just something to convert the pinouts from 370 FCPGA to Slot 1 so I can use the coppermine Celeron. As to whether the Tutalin will work is something I dont think is worth it anyways. My understanding is that the Tutalin has a 133 FSB. That wont work on my board as a top FSB of 100 is whats keeping my P3 733 at 550.So any Tutalin will automatically be underclocked. Looking at Intel website the top Celeron FSB 100 is a 1.4. My local store has a 1.3 socket 370 for $65 Can. I`ve looked on ebay and a adapter with NO voltage regulation can be had for about $15 Can including shipping. So in my mind is it wothwhile to spend $80 plus tax on something to upgrade this old beast or to get a cheap Duron/ MB combo (was looking at one at Tiger Direct) that can use my ram, case,etc.? The good thing is that this P3 733@550 gives me a bit more time to decide.According to the Norton benchmark (not the best I know but it`s all I`ve run) I`ve almost tripled my speed over my old Celeron 433@488. So like Misfit commented I think I`ll just keep my eyes open in the next few months for a 100 FSB CPU (P3 or Celeron). If not maybe a new upgrade in the fall. |

That wont work on my board as a top FSB of 100 is whats keeping my P3 733 at 550.So any Tutalin will automatically be underclocked. We've all been talking about the tualatin celeron, which is 100 MHz FSB and 256K cache like the coppermine P-IIIs. What you're talking about, at 133 MHz FSB, is the tualatin P-III. Looking at Intel website the top Celeron FSB 100 is a 1.4. Which is a tualatin celeron and not a coppermine. The coppermine celerons top out at 1.1 gig. My local store has a 1.3 socket 370 for $65 Can. That's also a tualatin. I`ve looked on ebay and a adapter with NO voltage regulation can be had for about $15 Can including shipping. If it doesn't say tualatin support then odds are it's a coppermine (or less) slotket and won't work with the 1.3 gig tualatin without modification. So in my mind is it wothwhile to spend $80 plus tax on something to upgrade this old beast or to get a cheap Duron/ MB combo (was looking at one at Tiger Direct) that can use my ram, case,etc.? It always just a 'few bucks more' for the 'next step'. While the Duron is a good processor, an XP1900 is only 10 bucks more than a duron 1.6 gig on pricewatch. But then you'd be hampered by the old memory and need to buy that over again. The good thing is that this P3 733@550 gives me a bit more time to decide.According to the Norton benchmark (not the best I know but it`s all I`ve run) I`ve almost tripled my speed over my old Celeron 433@488. Sounds like it's playing spec games with the P-III having SSE while the older celeron doesn't because 3x is too high. I might buy a 60% increase in basic CPU performance based on finger in the air guessing about 25% for the cache, 13% in CPU speed, and 12% from the FSB increase, but not 300%. SSE would only matter in something that uses it, like games. A tualatin upgrade will give you pretty much a straight linear increase over the P-III as they are the same FSB and cache size, except that the higher speeds don't scale directly with memory intensive apps like video encoding as 100MHz FSB can't keep. So like Misfit commented I think I`ll just keep my eyes open in the next few months for a 100 FSB CPU (P3 or Celeron). If not maybe a new upgrade in the fall. |

Thanks for that David, I wasn't sure (by memory) so said 1GHz. I had the same memory problem, and seem to be missing the last FCPGA celeron spec sheet, so I did a quick check on pricewatch and they list 1.1 gig 128K cache coppermine celerons. Although they've been know to have incorrect listings from time to time. Cheers, -- ~misfit~ |

Tualatin Celerons are excellent CPUs, having 256KB of on-die L2 cache (as opposed to 128KB for the Coppermine) Sorry misread the spec sheet on the intel site. This appears to be the top Coppermine like David said. SL5XR 1.10 GHz 100 MHz 0.18 micron cD0 128 KB 370 pin PPGA SL5XU 1.10 GHz 100 MHz 0.18 micron cD0 128 KB 370 pin PPGA Have to do another search tonite but I doubt it`ll be worth it. Think I`ll stick with my AMD plan.Thanks for straightening me out. Jeff |
