939 MB / CPU Combo Suggestions for OC

Ok, here is my situation. I am currently running a P4 2.533GHz. It is OCed to 2.85GHz. To do this I underclocked my RAM to DDR355 (177.5MHz; I have an Asus P4PE MB) and then OCed the FSB from 133MHz to 150MHz (~12.8% boost). This brought my RAM to 200MHz and my CPU top 2.85GHz.

But now I am looking to move on. I built my brother's AMD64 3200+ and it is very snappy and <b>quiet</b>. In comparison my P4 is a vacuum. I have on occassion mistaken my P4 for a vacuum (I am not joking... love the system, but the noise is too much).

I decided since I have a 6800GT AGP and it looks like the X800XL will take a while to hit $300 there is no point trying to go the long way of selling my 6800GT to get a X800XL to get a PCIe MB. The 6800GT should do fine for a few years if no other quality AGP GPUs come to market in the future.

So I am looking to get on the AMD64 / 939 platform and since I am sticking to AGP I am hoping this can be a reasonably priced upgrade. <b>My goal is <i>quiet</i> with stock cooling and overclockable. 2.4GHz with a 90nm AMD64 would be my base goal.</b> I already have 1GB of solid RAM, so I am not looking to upgrade my RAM for the overclock--I would like to do something similar to what I did with my P4. Set the RAM at a lower setting and the OC the system.

So, the questions:

1) What CPU? 3000+ (1.8GHz) or 3200+ (2.0GHz)? There is about $50 between these two. Getting from 1.8GHz to 2.4GHz is a bit more than 2.0GHz to 2.4GHz and I am not totally sure how the memory plays into this. Assuming that the AMD64 with HT works like the P4, a 3000+ would take a 150MHz RAM setting and a 33% OC for the CPU/RAM to get a 2.4GHz/200MHz. The 3200+ would be setting the RAM at 166MHz (DDR333, pretty standard) and then a 20% OC to get a 2.4GHz/200MHz CPU/RAM setup. So if I went with a 3000+ it would appear that I would need a MB with quite a few settings to accomadate what I am doing because 133MHz (DDR2100) is too big of an OC (50%) and 166MHz (DDR333) would be only a 20% OC when bringing the RAM up to 200MHz. Am I confusing the P4 with the AMD64 too much? What CPU would you guys suggest?

2) What MB? At least 8 USB 2.0, SATA (at least 2), ATA100/133, Gb-LAN. Firewire would be nice, as would 4 DIMM slots. Sound is not necessary. Something that allows the AGP slot to be locked for speed is a must. I want something that is OC friendly but reliable with solid drivers. Some flexibility with the memory settings will most likely be necessary.

3) What is a proper temp range on a AMD64 90nm at load?

Remember: Quiet, Stable, Stock Cooling, and Stock RAM (DDR400 Corsair Value Select). Affordable is also important, but a total of $350 for MB/Processor would be a good investment. I am also looking to get a quiet fan.

Also a link to a nice concise AMD64 OC guide would be nice :) Sorry this was so long, just wanted to give all the relevant info.

Ps- Current System is as follows. Note that I am only looking to replace the CPU/MB.

CPU: P4 2.533GHz (OCed 2.85GHz) with loud Areoflow fan
MB: Asus P4PE
RAM: 1GB (2x512MB) DDR400 Corsair Value Select
VID: eVGA 6800GT
Sound: SB Aud 2 ZS
2x HDD: 74GB Raptor SATA and 80GB Maxtor ATA100
DVDRW & DVD_CDRW
FDD
WinXP SP2

I would go with the athlon 3000(1.8ghz,90mm). those chips are excelent overclockers. People have been getting those babies up to 2.4ghz speed. those chips run almost artic to.

I've seen good reviews on the Epox 9ND class of mobos.. can get the 9NDA3J for $99, and the 3000+ is apparently the sweet spot for 64's now.

From what I've been reading, the memory you choose is going to be your main decision.

I'm currently looking at the 3000+/Epox/G.Skill LE combo. High FSB with nice timings at 1T, decent multiplier... seems to be the best price/performance out there.

First off, I have water cooling, but without increasing the voltage any, I got up to at least 2400 MHz with my 90nm 3000+.

MSI K8TNeo2-FIR
A64 3000+ 90nm
OCZ 512MB DC PC4000 RAM (2.5-4-4-7)
AGP GeForce 6800GT OC (BFG)
RAID0 Seagate 80Gb 7200RPM SATA's

Here are my current settings (had this baby running for 5 hours now, new rig)

CPU Speed: 2520 MHz
FSB: 280 MHz
RAM: 560 MHz DDR DC CL3-4-4-7
VCore: 1.60

I have yet to play with my RAM timings yet.

I'm rather bummed however, I can;t make this MOBO go any higher, the FSB selection maxes out at 280, and the multiplier is of course locked to a max of 9x. I know it will go faster, I just need a higher FSB or Multiplier......

I too once had money, then I got into computers...

I can get 2.5ghz @ 280x9 out of my 3000+ and Epox 9nda3j with Patriot XBL Pc3200.

2.5,3,3,6 timings 4HTT 1T, 1.45v on the cpu, and 2.7v on the Dimm.

Prime stable 3,3,3,7 280x9.

Prime stable 2.5,3,3,6 at 275x9.

with 2.7v at the Dimm on both, I havn't even begun to really push it yet.

This board is quite solid though, no problems as of yet. Need a higher multiplier, got a feeling this chip could easily do 2.7-3.0, depending on the ram and multi.

Yeah, looks like the most I can squeeze out is:

275x9 at 5HTT 1T 2.5,3,3,6 x9 2.7Dimm 1.45Cpu

Prime is good. SuperPi comes back 34s.

Weird cuz I did a 32s run earlier.. maybe better to tighten the timings a bit and run at 260 or so.

Definately should have gotten the 11 multi.

Ok guys, probably the wrong section to ask this but,

I'm prime stable at 275x9 2.5,3,3,6 3HTT (becuase I hear it's bad to push past 1000mhz HTT).

But I can push to 310x9 3,5,5,11 3HTT.

Is it better to have tighter timings, or loosen them and go for the mhz gain?

Just a thought.
