Memory + FSB + s754 Question

Hi, i am willing to sell my a64 3000+,msi neofsr,1024value selectram to a friend,
to upgrade to a s754 a64 3000+ (2.4ghz 512kL2), DFI nforce3

I want to OC my cpu to 2.8ghz so its a 400mhz OC, what is the best ram should i get.

I think a pc3500 low latency is a good choice. help me.

and BTW, is it dumb to still be on 754 when the 939 offers the dual channel ram. can i still have a dual channel ram on s754?

IF i want to keep a 1:1 ratio, i would need to OC my Ram to 280mhz ? = 560mhz

Would it be safer to get pc4000 so it would be a smaller OC?

Im lost, help me plz!
 
First of all, the 3000+ on any mobo is stock at 2.0ghz. Second, the multiplier is set at 10 stock, and you cant make it go higher. Third, if you want the best performance, you want a memory that is based on samsung TCCD memory chips. (Examples - ocz 3200 platinum edition rev. 2, Geil Ultra X 3200, PQI Turbo 3200(make sure it is the chip that has 2-2-2-5 at 3200), and G. Skill TCCD) Those are some, I think there are more out there. Fourth, 2.8 is an insanely good OC for a 3000+, most get to around 2.4-2.5 stable, if you get a good chip and have good water cooling then MAYBE 2.8. Also, a note on the ram thing, the TCCD will get you to DDR 300 with one stick in there, but two sticks I believe the best you will get is around 280-285, and no, you cannot have dual channel on a 764 mobo, but dont worry its not too much of a performance hit.

I hope that answers all the questions, and good luck, I am planning on getting the same setup.
 
Sorry ive made a mistake, i will not get a 3000+ but rather a 3400+ at 2.4ghz that i want to OC to 2.8ghz.

The thing is, if i want to OC my CPU, the only way is to raise the FSB, then my Memory Speed has to be the same speed then my FSB right?

So if a 3400+ is 11x218 or 10x240 ?

To keep the 1:1 ratio, i would need to OC a 200mhz DDR ram (400mhz) to 218mhz or 240mhz so it would make it 436mhz DDR or 480mhz (Thats quite high isn it ?

So, to keep the 1:1 ratio, even if my cpu is stock speed 2.4ghz, i have to OC my ram ?!

Woah im lost
 
Yes, faster memory will help immensely with your OC stability. Also, you should probably go with socket 939 as AMD is making that its primary desktop platform, and in addition to dual-channel, you'll increase your long-term upgradeability.
 
yes memory is a major help, kind of, the A64 doesn’t really need good memory because you can run a divider... and it doesn’t really hurt....but i still say get the best you memory you can...

You seem to think that a overclock is guaranteed..... but 2.8 is kinda outrageous, even if you fork out 279$ for a 3400+ (stock 2.4Ghz) it will probably only clock to 2.5-2.55, maybe 2.6Ghz

But it really depends on your cooling, with basic water cooling system; id say 2.6 with a 3400+ is feasible, but the same overclock is feasible on a 3000+ with the right motherboard…

2.8Ghz, ROLF
 
well, my stock coolign on a 3000+ 2.0ghz and a cheezy no agp pci lock msi neo fsr board was able to run 2.3ghz stable... its a 3000mhz OC, so i took for granted that a 400mhz OC was easy to do with the proper RAM/MOBO
 
if i run a 5:3 divider on my Corsair XMS 3200XL ram i can run benchmarks on my 3500+ @ 2.625 ghz

10.5 x 250
HTT = 1000mhz too

haven't determined if this is 100% stable yet, but I'm gonna do that tonight :D

i've had it @ 2.7 ghz, but it wasnt stable :( still not bad on air :D

wow 3000Mhz, OC, ....hehhehe...

Well, the reason most people but the lower end chips (ie. 3000+ 2800+) Is becaue there useing the same core as the 3400+ or mabey higher. So the 3000+ may have the same top out point as the 3400+. So why spend the cash on the 3400+ if the 3000+ will do the same thing? Alot of times the higher end chips are closer to the roof of there clock capibilties. so a lower % overclcok is to be expected. This is not allways true, but offen is. At least with the 3400+ your garenteed 2.2Ghz or 2.4Ghz (the 1mb clawhammer core is 2.2Ghz, the 512k newcastel core is 2.4Ghz) But if you get the 2.2Ghz Clawhammer and clock it up 200 Mhz to 2.4 you get a 3700+ :)

but i still say you wont get past 2.55Ghz with air cooling, mabey with the extreme air cooling (50$+) Thermalright or swiftech
