what p4 to buy?

ive had it with amd, ive been trying to get it to perform properly, trying to reach the 6 gb/s on the memory but i cant, i just cant. tried 3 memory pairs 3 different brands - no luck. I even drowe 300km today so that i could get my msi neo2 platinum motherboard replaced today and now i just got home and installed the new motherboard, no luck there either. So im not going to try to find the problem again, im switching back to intel, and i want a p4, but ive read so much about amd cpus lately that i dont know what intel cpus that has the best performance, can anyone help me out? thanks alot
 
6 gb/s on the memory? You mean the bandwidth through dual channel? and you must be talking over 400MHz?
 
well i would be satisfied with the 5650 mb/s that i have reached, but it bsods and reboots randomly and that is not something in fund of ;/
 
.. you also got an msi mobo. that's your fault, not amd's. but if you must purchase overpriced intel cpus, the 2.4c (or close to it) 800mhz fsb proc is the current sweet spot. don't bother with lga775, it's a total waste of money. also depends on what you're doing. amd hands down owns in gaming; intel is still better in many media applications partially due to software optimizations.

that said, I have nothing against intel. I just put together a p4 2.4c system for my gf; this is my first intel machine. got it mostly out of curiosity and to see how far I can OC it.

Dual-channel DDR400 = 200Mhz * 2 (for DDR) * 2 (for dual-channel) * 64 bits/transfer = 25,600Mbps = 3,200MBps = 6.4GB/sec. At least theoretically.

What were you using to test, and what were your results? You might not get exactly 6GB/sec. because of processing overhead in the benchmark.
 
sisoft says I'm getting about 85% efficiency, so that puts me about 5.5GB/s. this is with an Abit IS7-E2. I have never seen a system above 6 GB/s.
 
im not just worried, i can feel the difference on my system going from 4900 mb/s when the modules are running 2T going to 5600+ mb/s with 1T memory settings in bios

i WANT those 1T settings to work, a friend of mine has it and he gets 6 gb/s on his memory

only difference between his hardware and my hardware is that he has a 3500+ 0.13nm i have an 3200+ 0.9nm

we both have the msi neo2 platinum motherboard

he has some corsair 2x512mb 2-2-2-5 pc3200 modules
i have ALSO tested my setup with the exact same modules as he has - still problems

i have also tested the setup with my geil 2-512 ultra-x 2-2-2-5

AND some old hyperx pc3200 2x256

nothing will make it run without bsods or random reboots, nothing!
 
I find it unlikely that you will get more memory efficiency out of an Intel setup. The A64's on-die memory controller is widely recognized as being superior to anything Intel has right now. Intel has all but admitted that by perusing its own on-die controller for future CPU's.
 
Probably a bad MB or CPU in your system, especially if you tested with his RAM. The faster CPU is probably making the difference in Sandra (if that's what you're using to test the bandwidth). Did you try memtest86? Or your RAM in his board?
 
yes and im 100% aware of that amd is superior, but look at the problems ive had, it has costed me over £100+ to do this shit, in sending costs and fuel to my car

i dont want to buy something new for this amd and then have problems AGAIN
 
before i bought this amd i had a p4 2.8ghz, my geil ram ran in that computer for 4 weeks without one single bsod or spontanenous reboot so the memory is fine

and i dont think its the motherboard that its the msi motherboard that has flaws, not after i exchanged my 1 week old msi board to a new one today - same problems

but as i mentioned earlier, i do know this neo2 platinum is very picky regarding memory modules, so i guess my last resort before i ditch amd would be to buy another motherboard NON msi!
 
Hey, it's your money and your computer. I was just trying to help.

There's plenty of stuff here on AT about the new Prescott CPUs and how they stack up against the Northwoods. I don't know much about Intel motherboards these days, but I'm sure some searching would find plenty of info.

oh dont get me wrong, i value the feedback i get here alot! im just stating these things so that maybe, i can get to some sort of solution with you guys
 
is the rest of the hardware identical? same psu, etc? maybe your voltage lines aren't as stable and hence the crashes. maybe your other components are sucking up the juice. and even if it were the exact same setup (ALL the hardware is identical, same batches, just difference serial numbers, ALL the software is identical), you STILL wouldn't get the same results just because no two pieces of hardware are the same.

yes im aware of that, and as i said earlier, i would be _more_ than satisfied to run at lets say 5500 mb/s but i cant, it bsods, thats the catch ;<
 
What happened to your p4 2.8ghz that you said you had? It is still a good unit. If you are looking for a different Intel processor - the Northwood line is still preferred over the Prescott by a number of people.
