linkin was that on air cooling? IF SO SICK

Ya, with Artic Cooling Freezer 7 Rev 2, cooler 20€ not bad :D


http://www.arctic-cooling.com/catalo...ro_Rv2_l01.jpg

AC Freezer is a good and cheap cooler, i got the Freezer Xtreme Rev.2 for ~22€ and this can handle my i5-750 @ 4.1Ghz (prime!) :)

I had bad luck and the CPU i tested was a bit rubish. The most of them makes 4.0Ghz with 1.32 - 134v , mine only does with 1.379v, it can also be due to the motherboard but i doubt it.

200 x 20 =4ghz
Temps: 79º\80º Prime
Same cooler

yeah, i had now 2 i5-750...

1.) 4Ghz with ~1.29v / 4.1Ghz with ~1.34v
2.) 4Ghz with ~1.37v (not more tested)

i get later 2 new i5-750, hope they´re good as my first i5 :D

Nice CPU the first one, which was the VID?

good question, i think stock vcore was ~1.22v

Nice thread :up:
Just starting up with mine today Default Asus P7P55D Deluxe Living Review just benched at 3.8Ghz

Hey guys :up:

I managed to find some time at my work and test the Gskill 1600Mhz CL7 RipJaw.
This rams are awesome, i didnt have much time, so i didnt test them at 2200mhz, but i´m pretty sure that they can handle it, tomorrow if i have time i will test it.
The good thing is that they can achieve 2000mhz with only 1.58v, i didnt tested with less voltage since i had only 1 hour avaiable.

When compared to the other RipJaw series product, 2000Mhz CL9 1.65v, this one do the same but only with 1.58, and they are 1600mhz stock.
The 2000mhz CL9 Rams also should do it with less voltage than stock but i haven´t tested yet.
I also tried 2000mhz CL8 (1600mhz CL7 1.60 stock) with 1.65v but without sucess. Well, enough of theory:



DDR3 2000Mhz 9-9-9-24 1.60v

DDR3 2000Mhz 9-9-9-24 1.58v

DDR3 2100Mhz 9-9-9-24 1.65v
http://img40.imageshack.us/img40/585...2100cl165v.png

Nice one, will try that with my own set of ripjaw, thanks for the tip.:up:

Got 4Ghz earlier today. All bencheable, have been on it ll day without mishap, though it's not stable in OCCT or anything yet.

Nice result. I will run some tests with wprime and everest as well. I can see that i was the only one to have badluck on the CPU. It can only do 4.0ghz with 1.378v in cpu-z :rofl:

yes luck of the draw :shrug:
I did a couple of runs on occt up to around 1.36v (bios) but not stable yet, so to get any greater stablility may be joining you around 1.38v :shrug:

Hi guys,

Which "Clock Generator" do you use on those motherboards?
I've one here and i'm trying to use SetFSB :)

Thanks in advance

this is the clockgen on P7P55D Deluxe

http://www.awardfabrik.de/images/sto..._p7p55d/17.jpg

But i use TurboV Evo, works good :)

Thanks for the info Chri$ch and for the nice tip :up:

somebody can confirm that there is Back-to-Back Cas Delay option in bios?
i think i saw it in pro bios but not in deluxe?

thanks for your time and support

No B2B Cas delay option in Deluxe Bios ;)

But you can change it with CPU-Tweaker if you want.

Btw a short BCLK/Memory test with my Board...

http://www.abload.de/img/3.6ghz-32m-4jfvx.png

Aircooled Rams?

yes, its all air cooled ;)

short CL6 test

http://www.abload.de/img/ddr3-2100-cl6-1m6arr.png

no tweaks.

Switched to water today to see if i could get 4Ghz stable didn't work :)
So that's still a work in progress.
It's still benching nicely though :-
4130 20x206@x8 1,648Mhz 7-7-7-19

Have done a Bios Template as well, though it's for the bios it shipped with not the 0504 that LinkinParkBoy was kind enough to provide :up:

thanks chri$ch for your answer.

got retail 860 (L926B436).
expected little bit better than i920.
with ht=on over 4,2 is hard
with ht=off over 4,3 is hard
ram is ok till 2300 cl9 with 1,40v imc.
i think i got a bad chip and the story with good and bad goes on like with i7920.
this would all be ok if the 860 would be cheaper then 920.

New Bios :P

Cooler Master Hyper 212 plus does support on LGA 1156 $30 USD
About P7P55D Pro, it does support SLI however doesn't come with SLI bridge cable...there is no SLI bridge cable you can buy in the market except some used in ebay.
and P7P55D crossfire mode is x16x4 instead of x8x8

Seems like no one will review the P7P55D LE :<

It has been a while since it was released & @TYCUN i am sure the P7P55D crossfire mode is 8x8x and P7P55D LE crossfire mode is 16x4x.

You're right !
I just dowloaded the manual on Asus Website (new version, more beefy but was expected ...) and the specifications tells 16X/4X on Xmode.

IMO, it really sucks ...

I am totally agree with you, for the same price there is a Asock x58 extreme(best rating in newegg), that is why I got a economic version.

I'm thinking about getting the P7P55D "vanilla", can you recommend this board for overclocking? Or is MSI P55-GD65 the better choice?

I7-860 wasn't great but at least I5-750 is reasonable both at 1,600Mhx & 1,900Mhz:-
At least managed a sub 9m Pi 32m:)
I5-750 4.2Ghz 21x200Mhz Ram x10 1,900Mhz 8-8-8-22

Hi peeps im having real trouble trying to figure this out. im on stock cooler. When i power on. Fans move a little, leds flash then switch off every few seconds. When i push the onboard switch just at the right time sometimes system will boot. At first i thought it must be due to old bios...i managed to get in bios quickly flashed to latest bios 0606..I thought maybe its the memory so i tried some OCZ which are in the QVL...still same issue. I can boot but it takes forever.

I even got as far as installing Vista x64 everything working BUT when i shutdown windows & try and switch on again. Issue remains the same.. has anyone here had any similar experiences?? id really appreciate any input.

Once the system is running all is well it only happens when i first start the pc or after shutting down.

leds are a post procedure (diagnostic), you can disable it from bios, onboard switch is for memok test, manual sais 30 sec it last

My OCZ 850GXS PSU was the culprit. I used my Tagan U33 880Watts everything booted 1st time. Currently running i7 860 @ 4.1Ghz 1.35V DDR3 1530 CAS 7 7 7 24 1T

Temps are quite hot I need a good cooler im thinkin of gettin Corsair H50 when the 1156 bracket comes out.

Any other suggestions?? anyone using the Artic freezer Rev2 ? any good?

that's a bummer re PSU.
860 runs pretty warmish, i've been using aNoctua NH-U12P see link for more info Air cooling section. A bit dear but worth it espedcially as it comes with 2x fans which ratail themselves for around £30

I just installed my P7P55D, together with my new i5 750, and what can I say?? I am amazed!! Set Bclk to 200 in BIOS, changed multi to 20, RAM to 1600, saved and it booted right into windows, everything else is on "Auto"!!

I'm using the PC for over 2 hours now (Internet etc.), no problems so far, will run some Prime tomorrow to check stability!

nothing screenshot worthy yet, just a low voltage run to check out the turbo with C-STATE enabled and set to C6.

Prime95 Stable
Super PI 1.5XS 1M: 12.339s C-STATE disabled, 21x max multi.
Super PI 1.5XS 1M: 10.920s enabled at C6, 24x max multi.

Idle temps dropped from 38C to 32C with C-STATE enabled.

Can someone post the Bios settings for Manually Overclock a P7P55D Deluxe.

Please post a form with the settings of the Bios which i have to fix manually and please tell me which Voltages i have to screw for overclock.

TNX

Surprisingly, with my i7 860 and ASUS P7P55D I just upped the BLCK to 180 and set the multi to 20x and left everything else on Auto (though I disabled Turbomode and the likes). I was left with a surprisingly stable OC for a full 12 hours of benching.

I'm now tweaking it to find the sweet spot that I'd like to run 24/7. I'll edit this post later with my detailed BIOS settings.

While I'm browsing this, quick question for those of you out there who OC their memory (something which I haven't done in the past). I have some Corsair XMS3 8GB DDR3 1600 which is currently running @ 1480 @ 1.63v. I'm going to bump it up to the 1600hz should I be leaving my voltage at ~1.63 or 1.65v? Or maybe even drop it down a bit to 1.6 or 1.58?

I would try 1.65v & raise IMC (1.25-1.3) and PCH 1.15v if your using 8GB
also what are temps like with that zalman cooler? I was using vista x64 and i could clock upto 4ghz on my stock cooler and now ive just finished win7 x64 install i cant get it to 4ghz anymore. I need a better cooler ive purchased a Zalman CNPS9500A LED just waiting for the 1156 bracket to be released or i might go with corsair H50.

Thanks for the response, I'll try what you suggesting and see how stable I can get @ 1600mhz.

As for the Zalman, I love it. I've had a TRUE 120, MUX 120, and honestly I like this cooler the best. By far, at least in my opinion anyways, Zalman has the best mounting brackets and imho provides better/quieter cooling because of this. I always had trouble getting a good mount on my TRUE and MUX120.

As for the temps, my brother and I both have a Core i7 860, though he has the Intel DP55KG. Both of our stock temps hover around 29-33C and this is in a room where the ambient temp is between 70-85F (California). Overclocked @ 3.6ghz my temps are stable at 38-42C idle and 55-57C max under load which is quite nice. 3.6ghz has been my 24/7 OC for my past 3 rigs now, but it may be 3.8ghz since the temps are so manageable and safe.

Here's some benchs @ 3.8ghz:

Have a look at the voltages when on "AUTO"!! I found out, that my board gives 1.5V to my CPU on 20x200 when voltage is on "AUTO"!!
I also was happy that it was that "easy" to overclock with that board on "AUTO", but I don't want to fry my CPU ;)

Yes the voltages really get bumped up when using Auto. I'd done 3.8Ghz asa first clock on my 1st I7-860 with ram at 1600Mhz , auto used 1.36v i think it was :lol:

That's about 0.14v more than the max i've needed :-

damm, i have P7P55D mobo, and i7-860.
at stock speeds computer works about 1hour, then it totally freezes, and red cpu led starts shining after reseting.. sounds pretty weird. i have 2x1gb a-data 1600+ extreme edition memorys and i hope those memorys are reason for that problem?
It does same thing, if i have only 1module installed. dual channel or not, it still freezes.

How about that memory controller, what is integrated in cpu, is it possible that it is broken?

That's pretty rough 0lta, what settings ate you using? chances are your ram defaults to 1333, unless you have over ridden ram multi ?
Yes memory controller is on cpu.

well, default settings by bios. After that red cpu led started burning, i cant get my system up again, i have to clear cmos, and wait about 15mins.. then it boot up again.
Well, i will test those 1333 settings next, what u told me to do, and i will inform u later did it help.
I ordered new gskill ripjaws memorys today and i hope i get those on next week, so i can test my setup with those different memorys.
I hope i can test my cpu on my friend's mobo, same kind of board that what i have, so then i can be sure if that problem is on my cpu. (and maybe i test my memorys witht that mobo too)

But, let's see what we learn.. :rolleyes:

aye well hopefully , it's just you ram that's the issue. That would be best result.
Yes the Ripjaw is great, i'm running with 2 sets of it, great stuff . :)

It is known that the board has some issues with some Rams and will hopefully fixed soon..

I have this 4GB kit Gskill Ripjaw F3-12800CL7D-4GBRH Ive somehow managed DDR3 1920 @ 1.65v Cas 9 9 9 28 1T

Damn i wish i bought 2 kits now this memory is awesome. Works great on Asus. I bought it for £69 now prices have gone up:mad:

Yes they play really well, best ram i've had for a while. I got the 2nd kit as i've got used to runnning with 6gb on my x58 & windows 7 64. So it made sense to go to 8gb. Not pushed on to 2000yet though on 8gb.

I'm going to like my P7P55D, 20x200 was very easy on air:

nice one looks like you may have a decent chip there:up:

Well, I think the Vcore is a tad too high...I'm still looking for the right settings, but 4GHz out of a 2.66GHz chip ain't too shabby on air (Thermalright Ultra120-Extreme)...
Here are my other voltages for 20x200:

IMC-Voltage: 1.25
DRAM-voltage: 1.65
CPU PLL: 1.80
PCH-voltage: 1.05
CPU-Differential Voltage: 1000mV
CHA DATA: 0.525
CHB DATA: 0.525

Just in case anyone cares ;)

a quick note about BIOS 0606. Manually setting the CPU multiplier to 21 is the same as enabling Turbo. The option for Turbo disappears in the BIOS, but if C-STATE C6 is enabled the multiplier will still increase to 24 during a Super PI run.

So at this time there appears to be no way to enable C-STATE C6 and also use the 21 multiplier without it still increasing to 24.

where's that turbo option anyway? I haven't seen it on my vanilla P7P55D...

if you have manual selection of the CPU multiplier, turbo is hidden from view.

If the CPU multiplier is set to Auto, turbo will increase the multiplier to 21 or up to 24 if C-STATE C6 is enabled.

If the CPU multiplier is manually set to 21, turbo is enabled automatically, which is not an issue unless you wish to use C-STATE C6 and not have the multiplier increase to 24.

new bios 0711

update
so far
B2B cas delay option
fixed 21 mutli cpu speed at post
some crap settings for turboV evo.

Thanks for that info!!
But I think will stick with manual multi at 20x200 :D

just cast my eyes over 0711
has less options than 0606

Supershanks, are you running the ripjaws on your 1156 rig? you mentioned 2 different kits in your thread. the timings you have are tighter than what mine default, did you trial and error those, or were they recommended?

I'm getting ready to work on tightening up the memory at 1.60V, and was looking for some shortcuts :)

yep running with two kits :)
I'm running 8-8-8-22 which is the Jdec#3 SPD you can see below
http://www.images.clunk.org.uk/revie...clocks/spd.png
If you use everest Motherboard SPD Tab, there is more info on sub timings, I just manually enter the timings into bios, that's also why i put the long and short timing names in the template, it helps keep track :). I tend to start there as a rule, with most ram, but these didn't need any tweaking just run at that . Which means they could probably be tightened a little more?
Not got round to it yet :)

http://i869.photobucket.com/albums/a...uggler/SPD.png

Page 4 of your thread had a run with 7-7-7-19 timings and different subtimings than what I have, I was wondering where those came from. Are those the ones Everest shows for the G.SKILL F3-12800CL7D-4GBRH? Maybe I'm thinking of a different thread, but I thought you had a kit of those too.

yes was running at 1520 so i tightened tras up a bit i think.
difference in spds is down to rating , my kit is 2000.
this is spd per everest

Hey guys!
Are these voltages safe for 24/7 use?

CPU speed: 20x200
cpu voltage: 1.384V under load (idle = 1.472V => how to reduce this? enable Speedstep in BIOS??)
IMC voltage: 1.25V
DRAM: 1.65V
CPU PLL: 1.80V
PCH: 1.05V
CHA DATA: 0.525x
CHB DATA: 0.525x
CPU Differential: 1000mV
Clock skew: 200ps

These settings are Prime-stable, but are they safe to use 24/7?
Temperatures (air cooled) are about 70°C max. under load...

What do you think? Any hints on how I could reduce CPU voltage?

You may be able to lower your vcore a little by bumping up the VTT/FSB voltage a little, test it with Prime blend again. Another option is enabling LLC (if the board has that option) that will stop the vdroop and lower your idle vcore.

For those running 860/870's, are you leaving hyperthreading enabled?

I will test that later, but I allready tried a lot of different settings, I bumped up the VTT( "IMC" ) voltage to 1.40V, but it won't run stable...it seems like my CPU "loves" those volts.. :D
I also tried to that "Speedstep" - it works just fine, it reduces the multi, but not the vcore...:(

And I will try with LLC, too...but I read a lot about that LLC, and that it's not recommended to use it (because of intel's specs?)...

But thank you for your help!

Leaving it enabled, if you turn it off all you have is an expensive i5-750:shrug:

If you're running your 870@3.5GHz, just keep it enabled.

QFT! I'm looking at i7-860 and the Asus board now! If my trade goes through.

Yeah, it's an 860 at 3.5 for now, 21X167. Just not enough time for now to push higher, but that 3.5 was super easy. 1.25 volts, most everything else auto, but I did check that none were stupidly high.

edit: LOL

few updates:-
1) 170bclk Turbo mode using vcore offset:-
http://www.images.clunk.org.uk//revi...s/IMG_9194.jpg

Unfortunately not manged to get much higher than 170 and stable. would like to get a bit higher for a decent 24/7 clock, that ticks the boxes power wise.

So went back to brute force :)
4.11Ghz 22x187Mhz 1,870Mhz 8-8-8-22

Just to confirm that Noctua Noctua Noctua NH-U12P is ok with 4x ripjaw:

Not bad!
I'm running my 750@200x20@1.3500v, no errors with prime and OCCT 8hrs.
However, if I need to pass Linpack, I have to increase voltage to 1.375 and disable VT.

disabling Virtualization Tech made a difference? I was under the impression it had no bearing on overclocking. I usually just disable it because I don't use it...

also what IMC voltage are you using for that 20x200?

yup, it's either on if running turbo, else offf any other time.

IMC will be 1.225v... I also enabled llc, some ppl said it's bad to enable it, but looks like it's better for me to enable it.

hi folks, i noticed from some friends that there are huge troubles with some PSU like the LC Power or the Cooler Master Real Power m520 ... the boards simply don't starts ... someone have this troubles too?

first time for me to hear that, everything works perfectly with my Tt 600W.

Finally i got my new mobo, (deluxe) and new rams, (ripjaws 1600), i've made some quick tests, and looks good for me.
