Well I upgraded from my 1700+ to a 2800 Barton. My mobo is a DFI lanparty ultra revison b. My memory is Corsair Xms PC3200 512 dual channel. I am new to the OC'n scene and would like a little bit of help. I don't think my fsb is running @ 400. In the bios I have it set at 185x11.5. thats 2127, but in windows it says 2.31ghz. WCPUID tells me I am running 185 @12.5. system bus is at 370. I dont know much about the voltages and adjusting too much more. I am not sure, but I think right now with my settings, I am not running @ DDR400. Any help is deff. going to be helpful. My temp right is 35c with a load 39c. I am new like I said, but I want to learn all I can. I would like to see if I can get any more out of this, if I turn the clock speed to 200 it doesnt work. I didnt mess with the voltage my stock voltage is 1.60.
Thanks in advance.
 
Your multiplyer is locked, the standard multi on the 2800+ is 12.5 so you are better off setting it to 12.5 in the bios because changing it to 11.5 in there isn't gonna do anything.

Also voltage should be 1.65 but depending on your power supply you could be getting lower voltage then its set to, thus making it so you can't get that last little bit of performance out of the Barton. I would suggest if your on air that you try not to push the proc higher then 1.85 volts. Also if you really want to get the last little bit of Mhz out of the proc that you could loosen the timings a bit.

Temps seem pretty good so just see how far that thing will flex.
 
so I should raise the voltage, what about the clock? Leave it alone @ 185? It runs pretty smooth so... As far as the memory, their 4 spots to choose your timing. I dont exactly know the correct order the timings go. Thanks
 
2.31 Ghz is a nice speed and if you are happy with it running at a 185FSB and by all means stay with it. I would suggest though atleast trying to see what max speed you can get with your rig.

You can raise the voltage all you want, but I would try and keep it under 1.85, or 55* load which ever comes first :)

Now ram, you have
CAS Latency
RAS to CAS Delay
RAS Precharge
Cycle time (Tras)

The optimal memory timings for an Nforce board is 2-2-2-11 respectively, like my ram could only get 2-3-3-11 because it was cheap. The closer you get to the ram speed the better performance you should see.
 
ok thanks man. Everytime I put it the FSB @ 200 though, nothing. I think I am going to try 192 and it will be 2.4. As far as those ram timings they go in order like this in the bios?

11
I dont think these were the correct settings or the best for my memory. @ Corsair they say XMS3200 512MB 2-3-2-6. Maybe those are the regular settings. Thanks a lot though for helping me. Atleast someone anwsered.
 
Yeah some comps just can't do 200 which isn't a bad thing, 2.3 or 2.4 is a very respectable overclock.

The ram timings I can't tell you which order you will see, but if you look at the names of the timings they should be set like...

CAS Latency - 2
RAS to CAS Delay - 2
RAS Precharge - 2
Cycle time (Tras) - 11

The 2-3-2-6 that you have seems like the stock Ram timings, because its so low you shouldn't have any problem getting 2-3-2-11, or you might just get lucky and get 2-2-2-11 no problem. About 2-2-2-11 not being the best for your computer isn't quite correct, people have been messing with the nforce timings for quite awhile and have created a huge explaination of why 2-2-2-11 is the best way to go. I'm sure if you poke around you might find the thread relating to the nforce timings, I'm just to tired to look for it. :)

From just personal experience, when I changed my timings from 2-3-3-6 to 2-3-3-11 I saw a little boost in response speed of my computer when say surfing the web, opening windows, and even at startup.

Just remember though, use what your comfortable with.
 
11-2-2-2 probably aren't going to be the best timings for you at 185fsb. High tRAS settings benefit nforce2 setups only at high fsb, 200 or more I would say. Read this if you are interested in tweaking your memory timings: http://www.frazpc.pl/artykuly_wyswietl/212_en

Regardless, you shouldn't be using tight memory timings when you are still trying to find your max overclock. Find how far you can push your chip 1st, then tighten your timings.

Also changing memory timings without testing them 1st is a good way to corrupt your OS. Use memtest86 anytime you change timings and read up on overclocking the nf2 in general, you have a good overclockers board but it sounds like you might not have all the knowledge you need to really start overclocking.
