Guest twilight Posted October 14, 2004 Posted October 14, 2004 I am getting tired of playing with my NF2 mobo and 2500+ cpu and have decided to buy a dfi nf3 mobo. I dont know much about the different cpu´s to such a mobo so i need help choosing one, and where else to turn if not here What i can understand there are theese options for me (money based) Sempron 3100+ Athlon 64 2800+ to 3000+ Athlon 64 Mobile 512 cache 2800+ to 3000+ Athlon 64 Mobile 1Mb cache 2800+ to 3000+ Of course i plan to OC, so witch one is the best to OC? Do the AMD 64 cpu´s have locked multipel, or anything else i should know, so i dont buy the wrong cpu? :confused: Quote Share this post Link to post Share on other sites More sharing options...
reject Posted October 15, 2004 Posted October 15, 2004 a 2800+ mobile if you can get your hands on one. coupled with the UT, tht will be a great chip. dont worry you can lower the multi, and with this board you wont need to raise it. is there really a 2800+ CH? with a full cache? well thats your obvioous option Quote Share this post Link to post Share on other sites More sharing options...
Guest twilight Posted October 17, 2004 Posted October 17, 2004 Is a cpu with 1 mb cache generally a better overclocker the a 512kb cache ? Quote Share this post Link to post Share on other sites More sharing options...
New-B Posted October 17, 2004 Posted October 17, 2004 Just something to be aware of http://www.dfi-street.com/forum/showthread...=&threadid=2241 Quote Share this post Link to post Share on other sites More sharing options...
Guest twilight Posted October 17, 2004 Posted October 17, 2004 Ok....No mobile then...... maybe a 3200+ 1mb cache then ? Is that a good OC CPU? Quote Share this post Link to post Share on other sites More sharing options...
Popcicle Posted October 17, 2004 Posted October 17, 2004 .... get yourself the A64 3000+ (non-mobile) NewCastle as it wil be the CG core. Overclock the pee out it and never look back. It will have 512MB L2 Cache but you overclock it 200 Mhz and performance wise it will equal a chip of equal PR that has 1MB of L2 Cache memory. All for less $$.

Guest twilight Posted October 17, 2004 Posted October 17, 2004 Ok....that sounds good, but just to see that i get this right with the different cache sizes.....a cpu with 1mb cache outperformes a cpu with 512 mb cache if they both runs at 2000 mhz, is that right? If so....then a 1 mb cache cpu should be better to OC...IF they also are OC friendly, are they? I have also noticed that among mobile cpu´s the ones with 1 mb cache is at 62 w and the 512 kb at 35 w at the same speed, does it mean that 1 mb gets varmer?

Popcicle Posted October 17, 2004 Posted October 17, 2004 With the everyday apps that we all run the 1mb Cache chip will only give about 5% increase in performance. If a guy is into heavy graphics work such as photography etc then it's a different game. The 1MB Cache chips that are available today are of the CO stepping ( for the most part) and they don't overclock near as well. I only know of one vendor that still has a few of the original CG core desktop chips that carry 1MB Cache memory. These are very hard to find. So what it comes down to for overclocking is shoot for a CG core chip for best results. And leads you to the NewCastle model which carries 512MB L2. Unless you can pick up a 3700+ Desktop chip. And keep in mind that I'm only refering to Desktop models in all of this. The 62W chip is classed as a DTR ( desktop replacement ) and the 35W chip is classed as a True Mobile. However, the DTR is considered as part of the Mobil family. Quote Share this post Link to post Share on other sites More sharing options...
Guest twilight Posted October 17, 2004 Posted October 17, 2004 Ok....so if a buy a cpu with 512 cache today i probably get the cg core, not the co core ? If thats the case i think i know witch cpu to buy.....i will go for a 3000+ desktop cpu 512 cache, it seems to be the best price/performance cpu. As usual you guys has been to a great help.....many many thanx for your time, and replies. Quote Share this post Link to post Share on other sites More sharing options...
Popcicle Posted October 17, 2004 Posted October 17, 2004 True..... The 512 L2 chips will be the NewCastle model and they are the CG core. With a CG core chip you will have the option in BIOS of running 1T or 2T with your RAM. This is not an option with the CO core. ( because of the way the memory divider is programmed on the chip ). In BIOS.... CPC ( Command Per Clock ) enabled = 1T and disabled = 2T. Performance wise with tight memory timings 1T is the way to go. However, most folks find that using 512MB sticks of memory with high overclocks the 2T setting needs to be used for stability. And 2T hurts performace some. I see around different websites that folks using the NewCastle 3000 chip are getting some unreal overclocks. Good Luck and don't be a stranger to The Street! Pops.
