Asus P5B (vanilla) Overview

[Timbosan]

Hello All:

I found this page and form about a week ago and it seems to be exactly what I am looking for. I have built my own computers for years but I have never overclocked or changed memory timings, voltage etc before. I have had the P5B vanilla for about a month now and it works great. Now I want to start experimenting a little. I will update the CPU in a few weeks when prices go down a little. Can anyone recommend some memory, CPU and voltage settings I might try with the following hardware?

Thanks
Great Form

I dont have much experience with prescotts. Just keep vcore under 1.4v (air cooled) and keep temps under 60-70, best to be under 60*C.
vMCH - set to 1.2v and if needed increase to 1.45v
vdimm - 2.1v should see 900MHz @ 5-5-5-15 from that ram depending on the version (micron ic's clock better).
Set ram timing by SPD - disable this & set timing manually 5-5-5-15 for about the 900 mhz, test for errors & play with timings.
Lock pic-e frequency to 100 (increase to 101 - 110 if games/vid benches crashing)
Lock pci frequency to 33.3

That should get you started. Post back if you need anything

I got the RAM at 5-5-5-15 now. The SPD had it set at 5-5-5-18. It seems to be working fine with the new settings but I don´t real know what this means. I will buy a new CPU in a few weeks but I am not sure which one. Could someone recommend one with a good cost/performance ratio that would go well with my hardware?

Thanks

What speed are you at so far? There are some good threads in the general memory section that explain memory timings. They instruct the ram how to operate, basically how long to wait before executing a certain command. The '18' on the end is very 'loose', and your ram should be fine with 15, maybe lower. There are also subtimings, so a loose starting point would be (read down the screen):

5-5-5-15-6-42-8-11-12-15 - should be ok for 900MHz ~2.1v

standard timing for your ram at 800mhz is:
5-5-5-12-6-42-3-11-5-14

The higher you push it the looser the timings need to be. For a cpu recommendation, depends what you wanna do with it, but i like the e6300, e6400 as a match for the P5B and some PC6400. The e6400 is probably a better match for P5B & PC6400 as many e6300's can do 500 mhz+ which a lot of PC6400 cant do. 1000mhz+ capable ram isnt cheap.

Thanks for the great answers. Here is some info from Everest. I am looking at 3 different processors:

E6600

I will be doing a little of everything (some over clocking, Games, video editing etc.)

As always, any help would be great.

the e6600 is probably best for you if you can afford to pay that bit more. The e6300 can hit 3GHz + but you need nice ram to go with it. e6320 are nice due to extra cache, but again the ram would probably be your limiter.
With the 6600 you may hit ~3.6GHz, (9 x 400) and with the ram at 1:1 it would be running at 800 MHz. My 2c.

PS -- Good start with system, try running the ram closer to 1:1 (lower its divider & speed) and wind up the cpu it should do much more than that
