After that I'm not sure what I should start with. I know I should increase something til its unstable, then increase voltage til it is stable, then repeat til I hit max temp, but not sure which order to do things in, Core Multiplier, HT Ref or NB Multiplier first?
My goal is to as close to 4Mhz and stable as possible.
Also, what is he unlock cpu core option in the bios? Enable or disable?
Thanks for the help.
1. Intended Stock Voltages are from 0.825v - 1.40v, most claim that the Core volts should Not exceide 1.55v(?)
2. Order of Ocing....
1. First and best IMO is to find the motherboards Max Stable HT Ref Clk. You should hit a wall around 320-321Mhz. No matter what the voltages. But I found that if you bump it to around 335-338 you may get it to post again. But past that you will need to use the "OC Booster" modes. Mode 1 drops the HT Ref Clk by 20Mhz (or back to 200mhz, whichever is smaller) during post and will jump back up to the BIOS set Ht Ref Clk Mhz about 30-45 seconds after being in the OS (Depending on the BIOS, older BIOS it was about 30seconds after being in OS) (i.e. If you set to 240Mhz in BIOS Mode 1 will drop it to 220mhz during post and back to 240 45secs after being in OS.) Mode 2 will do the same thing but using a 40mhz Difference.
2. Find the CPU's Max freq. not exceiding the max temp on the chip which is 62*C
3. Next you can go with the Max Stable CPU-NB freq.
4. Max Ram freq. and then Lowest timings. (Max Freq. will need Very loose timings/ Lowest Timing will need Lowest Freq.)
4. If you feel so compelled you can find the Max PCI-e Freq. But most leave this alone and some have found better stability bumping the Mhz from 100 to somewhere in the 101-105mhz Range...
Lastly, "Finding the Max" refers to Starting with the increase of Mhz by 5mhz at a time first until you can't post any longer. Then back it down until you can post, then test in Small FFt's mode (Tests primarily the CPU) in Prime95. If you can't find 3+ ( or 24) hour stability keep lower Mhz 1 mhz at a time until you find the Max Stable mhz. Then if you like and fell comfortable, you can add a step in volts and rerun the process. This basically goes for the rest of the system. Timings will be more along the lines of Lowering the CAS First, test, then the tRCD, tRP, tRAS and tRC, testing between each and slowly working down all of the timings.
Hope this helps...

Now this board for some reason I'm needing 1.5v I have no clue why.. it just seems it needs more heat to it I guess lol But at least with stock settings everything in voltage(minus the ram at 1333 1.73v) with FSB 257 x 15, nb/ht x9 2300Mhz I get it 100% stable Prime95 on blend.
Its all about 4Ghz that is acting really weird on this board with my phenom, needing too much voltage I've already tested 1.4, 1.42, 1.45, 1.47, 1.48 and on all of them during any of the stress testings its either shut down BSOD or error during the test, it seems 1.5v is when its happy. I've definitely given a huge beating on that chip, 3 motherboards on all over 4Ghz stable 24/7 usage doing allot of video rendering since last year.
Anyways currently I'm still stress testing on prime the overclock I mentioned(same voltage setting still)... its all good so far I think about 2 hours already... but I still need to wait until 3 hours or more to be certain.
Forgot to mention I still haven't updated the bios since I received it(1.7), should I update/change the bios right now (and continue testing there)... I mean since I'm getting the cold boot with 2800Mhz do you have a specific bios version I should use to not get the cold boot issue.... I feel like I'm overclocking here but not giving its full potential capabilities.
Made the 3 hours on Prime95 blend.
Now I need a fix for the cold boot on 2800nb :/ so that I can go for the 4.10Ghz 2.8nb prime test
Try the 1.10 (1.1A0) for the cold boot fix.... I tested every BIOS including betas from 1.77b to the Current official 1.1D0 and 1.1A0 was th only BIOS that let me Cold Boot at x14 on the CPU-NB Multi....
And as far as this.... I was serious. but I wanted the faces to represent me being polite about it..... K?
[quote]Nowhere I've said that I know more than him so take ur bs somewhere else, I've only been showing my stable on 4ghz with simple settings & he's also helping me... so I don't know what ur talking about.[quote/]
So lets all just forget that it happened and focus on what we love to do and talk about.... Edited by Mastiffman - 8/1/10 at 6:25pm
