yea its alright iam happy with it, so what do u think of the el cheap board?

i have made good and bad experiences with biostar boards, they mostly overclock pretty good tho

 

[Corduroy_Jr]

i am happy with it have it 4.2ghz now about to hit a game of bf3 see if its stable enough

Hey everyone. I can finally join now. Woohoo. I just picked up a Ph II X4 940 be, upgraded from a Ph X4 9600 be. I'll be lookin at oc'ing it eventually. I did get it to 3.4GHz but my pc kept shuttin down on me randomly. I did a little research and found out after the switch the bios set the cpu volts as high as they'd go lol. So I reset to auto and running smooth now.

Anyone got any tips or similar sys to help me push it some? I'd like to get a lil more out of it for WCG.

MSI K9N2 sli plat
AMD Ph II X4 940 be 3.0GHz under a CM V8 at moment
OCZ fatality 2GBx4 1066 running at 800.
everything in my sys specs.

That chip should hit 3.6ghz but you may want to set it 3.4ghz and play with the NB to get the most out of it^^
I have this chip in my back up rig atm.

 

[popswala]

What all benifits am I gonna get out of this chip? I know there better then first gen Ph's and is much faster then what i was running before. Do I just wana up the fsb or pair it with the multiplier also? or use the d.o.t iirc. I haven't done any oc'ing for a while now.

 

[catnipkiller]

U dont need to move the "fsb" just keep it 200x and try to get your NB up for more ram banwith and try to keep yout HT click locked@ 1800 or 2000. Maby try 5-5-5 15 for timmings@800 ram speed

 

[Velvet Wafer]

Valid at 3.4ghz NB... it isnt stable, but amazing, how high i can go with the NB on this chip!

2000 mhz also work, but arent stable.... the IMC does like NB clocking much more than ram clocking

See your L1 write & copy? Try to get those in sync while maintaining a Memory read as close to 11GB/s as you can. 3.8Ghz on cores, anything above that is bonus!

Higher NB speed ~2800 MHz with 1333-Dram 7-7-7-21 or 2000MHz NB with higher memory and slower timings ? Now testing PhenomII-C2 with High HTT 2600+ and results are about the same as with HTT2000.

Tried to get my 960T to 4.0 Ghz.... didn't like it (blue screen on startup) tried upping the voltage a few times with no success

Backed down to 3.8Ghz @1.40 and still running fine at that speed

Will do some more checking around and will try again in a day or two.

Higher NB speed ~2800 MHz with 1333-Dram 7-7-7-21

This would give you more of an overall "snappier" feel. Now say if you could get closer to 1600 dram that would be good.

that are mere Benches, JR, as said, nothing stable.
The 4.2 are pretty easy to keep stable, so that is a good base
currently running these clocks, not sure if perfectly stable,but there was no jerkyness during general use, which usually is the case with instable settings on this rig, due to me going for 6-7-7 when 6-8-7 is stock at 1440 for these modules

when 6-8-7 is stock at 1440 for these modules

Well snap, go for that then with a nice 2.8Ghz nb frequency.

why 2.8?
3.0 are more than stable with reasonable volts, at that low memclocks

i wished my chip had a better imc like your chip with my high clocks then i would be set

for an unlocked proc, yours is already pretty awesome
unlocked,major clocks, not even bad NB and only c3 stepping!

The history build is complete!

Hi. This is what i have done so far: http://valid.canardpc.com/show_oc.php?id=2242274

My point is i had to put my memories auto to get that far. How i get them work like they should be or should i just leave them to auto when try break 4.7Ghz with air? ( i actually done that already but forget take screenshot. Window open and out side was -25C )

No way; that cpu should do 4.3Ghz easily.

Very nice clock. Your CPU voltage is 1.59 in that validation, its a bit high for 24/7 usage. The chip is only safely rated to run at 1.55, and 62c. Above that voltage and temperature potentially is causing damage to the chip. But it looks like your probably fine on temps for now with your window open.

What is the rated speed of your memory? because if you just want to overclock the CPU and not change memory and northbridge speeds just use the multiplier, and leave the FSB at 200. For 4.4, multi would be x22 with FSB at 200.

Hope some of that helps.

Edit: I looked at your system specs, and your RAM is rated at 2000? So now I'm confused. Because in the validation its 1366, (682X2) so your RAM is underclocked?

 

[de.das.dude]

4.7 should not be very stable on that chip.
anyways you have -25C temps
so worth a try

 

[catnipkiller]

New power unit and new bios^^

Yes they are, and that´s the problem. I cant reboot even to desktop if i try push over 4.2GHz cpu with manual OC memories so i have to leave them auto. If i remember right, in bios the setup was: cpu/nb freguency= ~2800Mhz, cpu/nb voltage=1.3V and NB voltage 1.2V


This clocks is only for Marks, not to 24/7

4.7 should not be very stable on that chip.

Yes i will try run 3DMark CPU test when cold again. Now it´s only -5C

New Results...
I guess from here on i wont see any big gains without buying low latency memory that runs about 2000 at cl6 or cl7, or going subzero, with a chiller,peltiers, or a phase.
If im able to get this thing to just even 4.3, without giving it more than 1.5 under load, and/or more than 3300 NB without giving it more than 1.45v NB, i gonna have to pat myself on the back, because that is something, i dont deem possible at the moment!
