Give or take, RAM running at almost 300MHz faster helps all that. What's your NB at?

I'm just happy at how the system runs with such a big handicap. I have some really nice sticks on my QX rig. Those are the ones I plan on benching with when I have some time. This rig will rock with some good RAM

It's completely possible. What is stopping me now is temps. Other than that I would assure you I would be stable at 4GHz without unreasonable voltage. I just can't do it at the moment.

It's a bit higher than 300mhz bro.... look again, NB? just a tad below 3GHz heheh
and thats 24/7

Here's mine. Haven't tried for higher. What voltage does it take for that 24/7 NB clock?

1.3875 Cpu/Nb....I also have a fan blowing cold air onto the NB and SB +mem, It's cool bro, and David loosen up the timings a bit bro! try 7.7.7.16.30 1T at the next higher Ram Div with current fsb and cpu settings.

[Paulieg]

OK guys, these are some of my current settings:

Clock ratio: 20.5
Northbridge:2000
CPU Freq. 200
HT Link Freq: 2000
Memory clock: 1600

CPU voltage: 1.50v
CPU NB Vid: 1.125v
NB voltage: 1.14v
Dram voltage: 1.63v

What should I tweak here? I'd really like to get 4.1ghz stable tonight.

[fullinfusion]

DAVID!!! Take the 3rd stick out bro!!! run 2 sticks and you will be clocking higher bro!!! shit I was scratching my head thinking why your having problems!!! If you like running 3 sticks than change the memory setting in the bios to GANGED mode! at least there you have a chance

[crazyeyesreaper]

forget going for 4.1ghz work on getting that NB speed higher thats where the Phenom II can gain more ground

take your NB up to 2600MHz and set the HT link speed up to 2100MHz.... change the NB /cpu to 1.250v and drop the cpu to 1.4750v... set the ram to 1.67v
That should work great for ya but dont tell any body hehe.... but really It should work better than what your using

[fullinfusion]

For me I find raising the HT up to 2100MHz while raising the NB up stabilizes the clocks.... My cpu hates anything over 1.50v and Chew says He doesn't know a Phenom that will boot at 1.60v Period!

Paul! what ram you running?

Sorry I'm late to the party, when you got your bsod....did it say anything about Pagefile or anything similar to that?

If so...and I imagine that is so...you need to bump your Northbridge speed upwards because the cpu is choking with it still at stock speed. I recommend at the least you try 2.2Ghz northbridge though 2.4Ghz is more like it for such a high clock.

In order to get those northbridge clocks stable you will be adjusting the cpu/nb voltage setting (the memory controllers direct voltage level). In order to get 2.2-2.4Ghz stable you'll be roughly in the 1.10-1.16v range as long as your board can handle it.

If that speed proves to be unstable then feel free to bump it up to 1.20v and it will be stable at those speeds without a hint of doubt. You can also adjust the NB voltage (not cpu/nb) to help with that stability from the stock 1.10v up to say 1.20v or 1.25-3 volts and that may help you get the cpu/nb voltage lower and still be stable at higher northbridge clocks. Doing so may help you reduce temps since the memory controller is in the same die as the cpu...increasing the cpu/nb voltage will increase cpu temps as well.

Hope that quick tidbit helps.

I do agree though that getting anything in the 4Ghz and up range is almost impossible to get stable with OCCT or anything like that without some super cooling. Even if you're not temperature limited it just seems like a wall that shall not be passed.

Hopefully you're the one on the other side of the wall!

It's still entirely possible just very hard.

This is what I use 24/7. 4ghz isn't worth the voltage/performance as there is very little difference for what I do.

One key to a good performing system is having your Memory Read bandwith match your L3 Cache Read bandwith. When this is out of whack be it AMD or Intel, this is when people complain about stuttering while playing games. With AMD systems, setting the correct north bridge frequency is the key. If the north bridge frequency is too high (which results in higher L3 cache bandwith) over that of what your RAM can keep up with in read bandwith, problems (stuttering in games for example) can occur. If the north bridge frequency is too low, bottlenecking occurs. So! The formula for setting the minimun north bridge frequency is (using 1600mhz DDR3 for example):

You want the north bridge frequency to be three times that of what you are running your ram at and more equals a performance gain to an extent. (RAM ~ 800x800 = 1600mhz) North bridge three times that of the RAM ~ 800x800x800 = 2400Mhz







Stock settings 4ghz below. 250 fsb, 1.438v

I 100% agree, as soon as you approach the 1.50v mark regardless of temps it seems these processors almost REFUSE to run. Going over the 1.50v mark has never really helped me to be stable at a super high clock...if anything it makes it far less stable.

On my board right now I can boot and run 4Ghz @ 1.440v....but if I turn the voltage up to 1.50+ it will barely (if at all) make it to or past the welcome screen. On any board I've used so far whenever I start to run into instablity as super high clocks I've found things to run better if I knock the voltage downward instead of upward. 4.1Ghz @ 1.56v was totally unstable on my last motherboard....but knock the voltage down to 1.53v and it would bench no problem...knock it down to 1.50v and it would still run...take it back up to 1.56v and you're lucky to get the welcome screen.

Paul! what ram you running?

Crucial Micron D9KPT's. It looks like I'm going to be 25 minutes OCCT stable at 4.0ghz. That's it for me tonight. Tomorrow I'll play around a bit more as I remember how to tweak these chips. Thanks for giving my memory a nudge.

[Kei]

Well said erocker and I totally agree.

@ Paulieg, these processors have so far proven to be very significantly more stable if you mix the bus speed and multipliers instead of just relying on multiplier alone regardless of the ability to do so.

Turn your bus speed up to say 250 - 260Mhz and put the cpu multiplier back to 16x. That will give you a cpu speed range of 4.0-4.16Ghz and I'm willing to bet much more stablity.

Running multiplier alone I can't really get 4Ghz stable for very long at all, but if I use 250*16 I can run 4Ghz all day long on 1.440v. I'm not alone in this either...give it a go and I believe you'll find it more stable no contest.

Make 100% sure that you keep an eye on the rest of the system multipliers of course. To get everything back to roughly stock levels change the Northbridge to 8x, HT Link 8x, and ram to the 1333 divider which will give you...

4.0-4.1Ghz cpu
2Ghz Northbridge
2Ghz HT Link (go no higher than this and dropping to 1600-1800 won't hurt at all if you have to)
1666Mhz ram

Kei

Edit: Also instead of wasting lots of time hoping for OCCT or LinX stablity you can do a quicker test with wPrime. Just run the 1024M test which will still take a good amount of time, and give you an idea if you're stable at all or not. The 32M test is much too quick and is more like a benchmark, the 1024M test takes MUCH MUCH longer and uses the same 100% cpu. It's what I use when I'm not in the mood to waste 4-6 hours using LinX,OCCT, AOD, Everest, etc.

id say up the multi by 1 and the Clock by .1-.5GHz

I will do some research now that thanks to you I have better insight on fans. I really can't wait. I'm ordering the case an H50 on the 29th!

soooo when you gonna buy it and show me da pics.... i want to see how you set it up.. i could use pointers on innards layout as i'm one of the only people i know with one, and the other 2 i saw here on tpu looked like crap inside

I really like the extra 2GB of RAM. I'll get some RAM soon bro, it's ok for now. I'll try ganged mode better though and see how it works for me.

I think the boys pretty much suggested everything possible. Let us know how it goes.

One thing though, NB speed is where it is at my friend, day to night difference when you clock that.

Bro as much as I think about it, I just did some math today with what I was going to do with my taxes and I think it's going to have to wait a bit. I pretty much got my taxes all layed out and my issue with being broke has been that I can't save up money. When I had the chance I didn't save up, and when I decided I was going to save up some money I was not able to because I needed the money I was going to save.

I'm going to use my taxes to pay off my only debt, pocket some cash to leave aside and get my important things out of the way. Once I do that I'll try to purchase the case as soon as possible. When taxes get here I'll see how things work out, if I got the spare cash I'll order the case. I'll definitely keep you guys posted though.

[exodusprime1337]

it's by far one of the most badass cases i've ever had, and i've had at least 30 different cases in the last 5-6 years, and nothing i ever owned has ever come close to this case, the setup is just incredible.

Just from pics and reviews I believe you. Unfortunate that I have to hold off just a bit, but It's for the better.

[exodusprime1337]

it'll make you appreciate it all the more when you finally get it, thats for damn sure!!!

Soon my friend. Hope is not lost completely for me to order it with my taxes. Gotta get the cash first and see how things go and how much I got left.

currentlybacking up 2 gigs of data onto different locations from extra drives to externals ive borrowed to dvds etc as i get ready for the shift to Windows 7 after which i need to wait for a 965 to drop in my lap anyway ill keep you guys posted on the tedious process
