I currently am running an AthlonXP 1800+ with the T-Bred rev A core in it. I managed to get the thing to 1.837Ghz 100% stable, but I want more. I'd love to get an Athlon64 3000+ and ASUS board, but I do not have the money for thyat. I was looking at a new AthlonXP so I can use my current MSI K7N2 Delta-L (nForce2 Ulta-400 board). My memory can only handle 333Mhz (or just a little bit higher if I'm lucky).
Now I want to make sure I get a RevB core this time. I was looking at one of these three:
T-Bred 2400+. It runs at 15x133. If it is not locked I can lower the multiplier down to 13x and run it at a 166Mhz bus speed for 2.167Ghz. If it is locked I will likely be stuck below a 150Mhz bus speed (likely around 146Mhz). This will heart my performance a bit with a lower bus speed and slower memory.
Thorton 2400+. This is the same as the T-Bred CPU, but is it locked or harder to overclock or run cooler? It actually is about $5 cheaper than the T-Bred core.
Barton 2500+. This one is about $10 more but only runs at 1.833Ghz, but uses a 166Mhz bus. It hjas a 11 multiplier. If it is unlocked I can raise it to 12.5, but that would only give me under 2.1Ghz. If it is locked I likely can not get it any faster than my current CPU.
Is the Thorton and T-Bred unlocked? Will I need a new BIOS update to use the Thorton for some reason? I likely will go for the T-Bred core as it is less likely to be locked or need any sort of BIOS upgrade. Do you think it is really worth spending $75 for about 400Mhz or less extra? Will I notice much differnce in games? Its so much easier when I am getting a new motherboard, CPU and memory as I can target higher bus speed options and such. When I'm upgrading it is harder.
Also will my AthlonXP 1800+ fit in my Epox 8KHA+ (KT266A) that my AthlonXP 1600+ (palimino core) sits in right now? That might make it a little more worth the upgrade as my 1600+ does not overclock at all.
