What was your cpu/nb voltage? That's the important one to look at. It sounds like you've left this voltage stock as 2.2Ghz is able to be run on the stock voltage, but going over that most times requires a bump. That depends on the board and processor of course. With the 955 I have now and the 790GX board I used to have, I could run 2.4Ghz @ 1.1v stable which is the stock voltage.

Kei

NB and HT Voltage stocks on the 790GX-M2RS are 1.2V.

Dude look at my CPU/NB volts.... I assure you that if the manufacture did not intend the volts to ramp up this much on the cpu/nb there would be heaps of returns to AMD.... Your thinking old school Kei.... bump the shit up bro!
My 79-T was on auto running 1.4ish 24/7 with out any problem.... This mobo in auto ramps up to just over 1.5v when clocked up over 4.1GHz.... times change bro, so you need to also lol... trust me, It can handle it with out any problems!
Listen to the man of Iron for once !!!!

I know I'm being cautious with my voltages, but you know that's just how I am.

The range from AMD that's 'safe' (I use that term loosely) air cooling is 1.35-1.50v obviously the lower side of that range is the 24/7 type of stuff. For water cooling it's a bit higher at something like 1.40-1.55v or so.

I just don't run voltages that high because I never run my system OC'd 24/7 because it's something I just don't need really. Stock is already more than enough speed to do anything so I focus more on using as little power as possible.

With the northbridge though I do like running it higher than stock rated speed because it feels really nice and depending on the speed doesn't take a lot of volts. I don't bother with 3Ghz clocks 24/7 because it takes tremendous voltage compared to any other clock, and it's just not worth it to me. This board isn't quite as easy to clock the Northbridge, but on my two other boards I used to use it made less than no sense to need 1.37+ volts to get 3Ghz when 2.8Ghz needed only 1.25-27

2.6Ghz could be had as low as 1.16v which makes the 3Ghz clock even LESS appealing to me. If I could rock 3Ghz @ 1.25v or so I'd be all over that! Sadly I've only had 1 board that could do that, and it wasn't 100% stable at that speed.

I don't remember the max voltage the cpu/nb can be set at on this board, but I know it's something out of this world high like 1.7v or so. I remember the cpu volts can be set to 1.9+ volts...I do wonder who did the bios on this 'budget' board lol.

OK. I've been out of the loop with AMD for about a year, and wanted to see if I lost my touch with these chips. So far, not bad.Obviously just a short test though. I'm looking for 4.0 before I go to bed.

Good job so far Paul. 4Ghz is right withing reach bro, just keep at it

Respect bro! I wasn't shitting on your parade!

I run 3.89 + NB at 2940MHz @1.3875v with memory timings of 7.7.6.15.25 1T @1.669v 24/7

Cpu/NB volts?
I wouldnt think twice of running 1.48v 24/7 as long as air flow is good.... Im looking at my NB temp with the side on and she's running 34c top

Post a shot of AMD OVERDRIVE to see the voltages so we may be able to comment on a stable setting please

Paul post a shot of the "performance" tab of AOD overdrive. Look at my screenshot for example.

 

[Chicken Patty]

Let's see how this works for me.

Very loose run without shutting anythign down, RAM at 1066.

Testing at 4.06ghz. Here's my performance tab. It doesn't look like yours.

I'd thank you, but see.....here's the thing

201Mhz HTT speed

Try again and we'll acknowledge your awesome with a song on the mountains.

I won't try bus speed with this RAM. causes instability, I don't even know if this damn thing runs stable at 1066. This RAM really sucks on an AMD rig. Don't worry though, when I have a bit more time I'll bust out my secret weapon and show you'll pansy's how it's done

 

[PaulieG]

Here we go with a quick wprime run. I'm off to do an OCCT linpack run now.

 

[Chicken Patty]

Good run so far Paul. OCCT will really tell you if it's stable or not. Wprime is misleading at times.


BTW guys, running RAM at 6-6-6-20 1T. How do these #'s look. Remember it's running at DDR3-1066.

Im running I7 ram bro! Its Triple channel OCZ rated @1600MHz stock @ 1.65v
your running D9's.... you haven't got something set right in the bios bro

Me D9's? I wish. Yours is rated at 1600 stock, mine is rated at 1066 stock!

Kinda slow bro for running tighter timings with similar clocks bro....

What?
I swear your using D9's that CD recommended? what slots the sticks in?

I think you should look at mine again

Your memory Latency is obviously much quicker since your RAM is running at 840 MHz, mine is running at 547 MHz.

Our L1 and L2 are identical, my L3 is slightly quicker. at 5.5 ns

What?
I swear your using D9's that CD recommended?

Naw, these are not D9's, not that I know off. Even with the i7 they didn't clock that good.

 

[PaulieG]

OK. I'm BSOD at 4.12ghz at on OCCT only a minute in, with the settings as listed above. This is where my bad memory and lack of recent AMD experience comes in. I'm thinking that it's not a vcore limitation, but I'm just not familiar with the more subtle stuff with these chips/boards. Thoughts?

not quite bro, look at the copy speed! it's quite a bit faster even though its a tad slower for time

You mind posting some of the settings in the BIOS and we go from there?

 

[erocker]

You'll be very hard pressed to get anything over 4ghz OCCT stable. I can get 4.2ghz.. well 4.19ghz bench stable and that's it. With a 32bit O/S it may be possible. I have yet to try that out.
