nkresho: Great blend run, keep pushing.

[andressergio]

I'd say it is.

It hasn't hurt my CPU, neither has 1.7V.

[andressergio]

guys it is safe to use LLC on the UD3R for 24/7 4GHz @ 1.23v?

yes mate no problem here been using since a year and vcore to bench up to 1.6 set on bios

hey Tom stop pushing poor nkresho just started i think we are more anxious to see the results at 4500 than him lol

Cheers mate
Nice OC nkresho

early report for 3.6 is ~1.1v at load to pass linx , i havent look around for similar setups, but seems to me just an average 9650, nothing extraordinary...


O/C curve till now:
3.2 -> 1.008v load
3.4 -> 1.056v load
3.6 -> 1.104v load

PS> temps start to worry me.. if i get 60 C at 3.6/1.1 at (hypothetical scenario) 4.0/1.2+ how high ?:S

yeah mate that's cauz its such a low vid mostly are for water not air but that's just inmo.

Very nice chip mate

after setting 3600 the wolf wakes up slowly slowly :P, eager for more... but have obvious difficulties to raise fsb with 4 dimms on x38-dq6. After trial & error , i found the most stable GTLREf settings for 425 fsb and minimum voltages (VTT +0.1/1.21v, MCH +0.075/1.33v) , to be GTLREF 1 : +3% , GTLREF 2 :-9% , kinda weird ?? , such Voltage Delta between these two , is reported to shorten chip's life? , assuming most ppl use a plain 0.63% (or equivalent, both at -3% in a GB board)
ty in advance again


EDIT : more VTT :s (+0.1)

you will have troubles upping that baby on that mobo mate, best choice for quads is UD3P i had a nightmare on my asus MF2 with GTLS and all that, so simple on the giga...

Here are some quick results@4.5. This obviously is not Prime stable yet(will probably need 1.45V), but so far stable enough for my purposes. Yesterday I was priming at 4.4 and kept getting errors no matter what Vcore. Temps were topping out at 73C. Some of you guys have talked about this issue, Prime failing if temps get above a certain point. I realized my 38mm fan was installed backwards (pull config), switched it to push config and temps went down to 63C top, and no more errors. Im sorta glad I didnt get one of those crazy low vids, as I really am liking my temps at my Vcore.

[nkresho]

Wow, nice clocks viper. And on air nonetheless.

I can't wait until I get to 4500. Soon, very soon.

we are also waiting lol

Great viper wellcome to the 4500 club

[OC Nub]

Great job Viper, congrats.

Thanks, nkresho. I bet you will get there just under 1.3V, lol

[nkresho]

^I hope. Not sure though.

Question for you guys...

When prime runs fine for a number of minutes, then everything freezes up, what is it usually? I have found that with vcore, you'll typically have a core or two fail, but it will keep priming the others. I keep having freezes, not bsod, not cores failing. Wierd. Any advice?

One sec, i'll add my overclocking notes...

I recently was able to accomplish 12hrs of Prime95 blend + IBT with 1.32vcore on a much higher vid chip (1.2125). Those with Turbo Profile and rams at 1200Mhz 2:40B (PL8).


4500Mhz with less then 1.30vcore it's perfectly doable on a low vid chip using slack ram timings like on standard profile and ram's on 1:1 strap.

Nkresto: the freezes you're having are most likely to be ram related. You will probably need more Vmch or Vdimm to correct the problem.

Thanks for the insight.

I'm guessing mch then, as I'm running the same "big boy" gskill pi as ocnub and andressergio.

Here's a copy of the last two pages of my overclocking logs...







trying the ibt stable settings with higher mch and mchref right now... we'll see.

[andressergio]

Agree with Jor, im using 1,46MCH and 2,2Vdimm set on bios for my 24/7 4500/1200 PL8 turbo on tight timmings (jor the ones you stored on my oc profiles lol)

Jor that's a so damn good chip that i dont get tired of lookin' such an impressive low 4500 OC's... i tried on mine and not even at 1:1 wich loosen timming i could go less than 1,392vcore

Did enabling all CE1 states and all that you have enabled help on your OC or you just activate all after stable ?

Cheers
Sergio

[OC Nub]

Very impressive Jor. That is one hell of a chip, I think the guy clocking it has a lot to do with it also. Always nice to see your posts.

The absolute truth right there.

[andressergio]

The absolute truth right there.

truth is no offense

[The Viper]

lol, its gotta be true...

heh sergio can u link me to some of ur Bios settings past 4.5

[papatsonis]

i give up trying any more with x38-dq6 , two afternoons spent for nothing, cant get stable 450fsb , no matter what... (with 1.475 MCH -too high already- get random lock ups..), ill stay at low 9x400/1.1 and be "happy" :S .there is a hope in future if i change my ram to some fast 1066+ so with anything than 1:1 the chipset will be much more relaxed.. , but for now "nisafi"- enough

I know its hard mate but i must tell you that no go with such a good quad on that mobo, sorry to say but lots of us went throu the same, you will have great fun on a giga ud3p and its cheap
