ASUS P8P67 Pro/Evo/Deluxe OC discussion thread

[kidsafe]

when you guys did the rma did you keep the sata cables or anything else in the box and not get charged for it? im doing a advanced rma and was wanting to know

I only kept the new board, put all the new accessories in my old box and sent them back.

Anyone have opinions on the Digi+ VRM spread spectrum? Asus claims it improves stability, but I think it may just be marketing bs. enabling it requires using standard or optimized Digi+ Phase control (not usable on Extreme), and disables manual VRM Frequency mode

I tried enabling both Digi+ VRM spread spectrum and CPU Spread spectrum, and I'm still 12+ hours prime stable. doesn't seem to make a difference to me compared to Extreme/350MHz but I do wonder how many phases are active in "optimized" mode and what possible effects on stability it might have. although their overclocking guide recommends Extreme/350MHz so who knows. maybe these CPU's are so hard to get long-term stable because of radiation/EMI effecting other components? i swear my last board (gigabyte UD4) was nearly impossible to get stable. (but could have been a bad CPU) so maybe there is some truth to Asus' claims?

[kidsafe]

If you're OCing in the 4.8 GHz range or more, you're going to want your Digi+ VRM power phase control set to Extreme. Use Spread Spectrum and you're making each individual phase work harder occasionally for the sake of insignificantly less EM interference and power.

What's the difference between regular LLC and leaving on auto?

so, say a deluxe with 16 phases may be using 8 or 12 during full load with Optimized? isn't that still a bit overkill?


also, does anyone really know the impact of using the EPU chip?

[LeetMiniWheat]

warning to anyone using EPU, the "Quite" option for fan control seems to turn off the fans entirely. I had this option enabled for "Max. power saving" and it made my computer overheat and shut off twice. maybe it's fine without an overclock, who knows.

also I'm pretty sure on "auto" it switched to max power savings during gaming since I had an incident where the cpu fan stopped in the middle of a game. so the "auto" EPU option doesn't seem very smart at all.

I'm going to guess that auto settings will allow you to change it in windows. But I could be spreading FUD, since I don't have that board. I've never seen an auto setting for LLC that actually enabled it...

B3 Deluxe on 1305





the memory was on stock volts as well (1.65)

[cstkl1]

i am sometimes curious about the claim of cpu overvoltage protection.

ran 1.48v close to 85 c on linx with it on.. nothing happened.

[fasterklander]

I'm with ASUS P8P67 EVO with BIOS 1305 and can't boot 1st time. I tried to change PCI-ex vga boot sequence and I have to turn on 2 times to start the PC ¬¬
Now I'm for 24/7 on air with 1.30v set on BIOS. On load I have 1.288v or 1.296v
This is a picture that is running BOINC 8h



My 2600k scales some well I think:

4500 Mhz at 1.30v
4600 Mhz at 1.33v
4700 Mhz at 1.36v
4800 Mhz at 1.39v
4900 Mhz at 1.41v
5000 Mhz at 1.44v

It runs Linx at every speed, but for long BOINC calculations I think that is better at 4500Mhz
The memory is running all in auto at 2133 Mhz
Can anyone help me to solve 1st Boot failure and don't reset system on every Boot?
Autoanswer--> On BIOS... Advanced-->APM-->PPower on by PCIe-->Enable ( I wil try this tonight ^^ )

Regards!

Scales better than mine. Add about .04v to all of those and that's mine. Can't wait for Ivy B.

yeah that is real good. mine curves up higher in the 4.9/5.0 range though. I think for 5.0 I'd need 1.475-1.5 which I'm not comfortable with. but 4.9 is stable around 1.43

does BOINC have any error checking like prime? maybe you're sending in bad work units? I've always wondered that.

in my experience that's usually something to do with RAM or memory controllers. my old sandy began to degrade after torture testing for 2 months and she wouldn't even run 2133MHz at stock anymore. I would try downclocking mem to see if it's really mem or not. then if it is, you could try adding more VTT, vdimm, or loosening some timings.

Edit: I see you're running Ripjaws X, I have those too. aren't they rated for 9-11-10-28 1.65v? you seem to have them 9-11-9 1.6v, maybe that's the problem? I didn't have much luck tightening mine anymore than default. even if they pass memtest they fail prime blend or IBT.

Thanks for the quick reply.

My kit is this F3-17000CL9D-4GBXL which is rated 9-11-9-28-2N @ 1.6V here

[fasterklander]

I just run linx at 5Ghz on air set 1.44v on bios.
On idle it has 1.43v and full has 1.45v

See the picture



It has nightmare temps xd

Try testing linX with more memory - click on the all button by the memory about 3-5 min after you boot up to et at least 2.5gb...
Try switching to 1T command rate too.

oh, right. my mistake. my 8GB kit is 1.65v and your 4GB is 1.6. interesting. either way, I would mess with VDIMM or VTT to see if it makes a difference. with high overclocks it does produce more memory bandwidth and may pull the rams slightly out of intended spec. or maybe you got a lemon of a stick, it happens. G.Skill forums are also very helpful.

When will we be able to RMA our boards for the newer ones?

[babalouj]

I have already RMA'd mine and got the new one installed.

Try some Prime95 Blend? Here's my 30min test. 1.38v from bios..
Memory @ 2133MHz 9-11-9-27 1T.

Happened to me as well.
Linx avx and prime95 small ftt was passing on a given vcore but not blend.
more vcore solved it.
I know it sounds weird but i'm not the only one.

hmm, if this is the case... then my suspicions about larger FFT sizes stressing the decode engines harder may be true. 1024KB FFT's seemed to fail the most on me. and if I'm not mistaken, this is why we stress with prime95 because the decode engines are the weakest link on these new chips while LinX/IBT mostly stresses the FPU.
