first off my computer:
DFI Lanparty Sli
3200+ winchester, with a Venus 12... runs at about 27C idle
2x1gb supertalent 3200, 3.0CL
7800GT
500W ultra-xfinity PSU

I wanted to get the CPU up to 2.2Ghz 220x10 multiplier... I put the ram to a 6:5 so it would hit apporximately 200 still... I put the HTT to 4x so it wouldn't go over 1000... I can't get the bios or windows to boot with the core voltage of 1.36v or when I up the voltage to 1.45v.. what do you think is holding it back?

Also I never really touched the CPU vid control.. I just adjusted the CPU VID start-up value to try to get 1.45v
 
Just a question, if you knew you were going to overclock, why did you get that power supply?
 
First thing you should do when you get a new rig and want to test overclock..

Drop ram to 266 divider (133, or 2/3's) want ram loose (8-4-4-3 2T).

Drop HTT to 3x

Give 1.40v to cpu ( i had to run 1.5 on my 3200 winnie to get it to 2.4)

Leave chip at 200 and start going up slowly...1-2 FSB a time.

NOW this is going to take a LONG LONG TIME, days if not weeks to get it. If you dont want to take the time then its your system. However, this this be done to test stability. The more shortcuts you take here, the more you will wonder why its not overclocking.

Now you have this setup you know that the ram will not be a issue, your cpu volts is around what you want. Each time you move up your FSB, remeber to make SMALL Jumps, no more then 2-3 FSB per jump, i do 2 myself. Once you change the setting, go into windows and stress test. I use Superpi for quick checks, i do a 1-2-4-8m Superpi in a row, if that passes, its on to PCmark2005. If that passes, on to SP2004 (Stress Prime 2004, by Johnny Lee. If you dont have this go get it, its free). SP2004 is the same as Prime95 (code is exactly the same). However, SP2004 has alot more info to offer. If you cant SP2004 you machine at least 8-10 hours, then i would drop it down 1 fsb and start from SP2004.

Now when you reach a wall, move up the cpu volt 1 notch a time and retest, if it gets farther and your temps ok, then you should be good, if it fails still, but gets alot farther..maybe 1 more notch up. THIS IS UP to you what to run at. I was at 1.5 and around 50-52C on load. However, i would NOT go any higher then about 1..55-1.6v.

Once you cannot prime anymore any higher then what you are. You can start testing the ram. For that:

Keep voltage at what you found to be stable from testing CPU (see above)

drop your CPU MULTI (not LDT/HTT) to 3-4-5x, you choice

change your ram to run at 1:1 ratio and timings at 8-4-4-3 2T.

Voltage will be stock for now.

Start your FSB at 200 with the ram running at 200.

Boot up and start testing....moving up 1-2 fsb each time, stress test again. Once you reached your max. Start off with timings.

If you decide to test more on your ram its up to you, testing with ram @ 1:1 loose timings, vs ram at 5:6 tight timings. Just make sure that you make adjustments 1 at a time and stress test in between.

Once you have found where you can go any higher, then its time to blend your test results and find a sweet spot.

Like i said before, this will take a LONG time...however you just looking for the max stable overclock on each cpu and ram. By doing each peice single, you know that the other isnt a issue.

Totally agree, thats not a very good PSU and you probaly better off with something better if you going to overclock.

do you know the stepping? the later winchesters sucked balls, and could barely do 2.4ghz. you might want to consider using a bit more than 1.45v... barely a 3.5% overvolt :p :D
 
gotcha .. i have a Thermaltake Silent Purepower 480W around.. I guess that might be better.. but I though the Ultra-x-finity was a more than enough for a little overclocking

also I overclocked in 2Mhz intervals... and I just tested it by running games...
 
I'd say that a Thermaltake PSU wouldn't do anything good for you. I'd never trust one in any rig of mine.
And what's wrong with the Ultra x-finity? I have an Ultra x-finity 600 watt and I love it.

from the bios or with clockgen?
 
I was stable at 2.77 with the Xconnect PSU.

What am I missing? I hear alot of people bash the X-connects for stability... But with a multimeter I've never seen anything more than 4% over spec on mine. (I've never seen anything even 1% under spec either).
 
I use the bios... but the lan party bios is pretty complex ... I'm probably missing something

the guide in my sig should be a good start then :p
 
Why 2-3 Mhz bumps? My first was +50 .. because i have ddr500 soo

Code: 
                              stock          OC

HTT                        200             250
HTT mult                 5                4
RAM                      200(1:1)      250(1:1)
HTT freq                 1000           1000
CPU                      1800           2250

I did this because i was confident my system would run stable.. ram is not OCed.. HTT is exactly at 1000 .. now for more i would increase +5 or +10. Is there anything wrong with doing increments of this much? I'm new to OCing my self :p
 
I think the problem is my ram... can some ram not work on wierd divders like 5/6?

I have CL 3.0.. 3-3-3-8 at 200mhz ... so it's pretty loose timings to start .. when I set my bios to default it works perfect... when I change the ram divider to 5/6.. it doesn't even boot to the bios... then when I return to defaults it works again.. so I guess my rams the problem.. but I'm not running it over 200mhz .. so I don't understand why it would be the problem.

I guess Ultra changed their attitude. My bad, I thought that ultra was still into the whole looks over performance thing. They sure changed. If they keep it up, I might see them as a serious company.
