CPU V-Core

 So I received my computer about a week ago now and have enjoyed it quite a bit. Massive improvement from my old PC by leaps and bound. I am worried about one thing though.

DS was able to overclock my computer to 4.7 GHz but my V-Core is very high even when I first start up the PC at 1.48. From what I have read that is high even under full load and I have got that at idle. I really don't want a dead CPU in a years time. Would this be something I would need to call DS about, or is there anything I can do on my end?


Thanks

i would call like dst said. For reference you should be able to hit 4.7ghz at right around 1.375V

Originally posted by DST4ME Ya tho its different from cpu to cpu I have also seen lot of 2600k with around 4.5Ghz - 4.7Ghz at under 1.4 vcore.

i completely agree each cpu is different but that v-core is way to high even if its a bad chip. Almost as important as v-core is your line load calibration(v droop). If its set to low and allows the v-core to droop your gonna have to put alot more voltage into it to stay stable. Higher line load calibration will allow you to run lower v-core. my chip is at 4.5ghz stable at 1.35V =)

 So I ran LinX and these were my results I got after running it for just 5 minutes. Those temps seem pretty high.

did you call them to ask about your v-core. If you wanted me to help you i can also help if you cant call do to work or what not.

I'm a bit confused, didn't you ask them for the highest oc you can get with the vcore staying under 1.4? only load numbers count.

I mean it looks like you had a 4.7GHz oc with 1.45vcore, now you have a 4.5Ghz oc with 1.48 vcore? thats worst of both worlds, lower oc and higher vcore.

the point here is to lower the vcore and try and keep the 4.7Ghz oc, if not then say vcore of 1.39 and the highest oc that can hold, which should be around 4.5 to 4.7Ghz.

@ DST
 I did ask them for as high of a oc that I could get below 1.4. We tried twice changing the voltage from 0.120 and then to 0.110 but it didn't change my vcore much. I am thinking though if I gave it a little bit more time I would have saw it lower at 4.7 but I didn't give it enough time looking at cpuz.

 The tech said to give it a week to see if my performance lacked at all with the new voltage but I am still not happy with the way the results came out. The only plus side I got out of it is my PC no longer stays at 1.45+ but lowers to 1.1 when I am not doing much to stress the cpu.

Temp wise I am also puzzled about because my room temp is usually 64-68 right now yet my temps when I run say LinX are jumping up to high 80's and low 90's in less then two or three minutes.

@Rice

Here are the values I found on my OC:

Internal PLL Overvoltage - Enabled

Load Line Calibration - Ultra High

VRM Frequency - Manual at 350

Phase Control - Standard

Duty Cycle - Extreme

Cpu Current Capability - 100%

Offset is set to plus

Cpu Offset Voltage - 0.110

Dram Voltage - 1.65000

Thank you both for your help and replies.

When the tech helped me with the same problem, my offset was changed from 0.120 to 0.065 and that gave me a load vcore of 1.37 at 4.5ghz oc.  Ran prime95 and it was fine.

 So I changed my Cpu Offset Voltage to .020 like you said and ended up with a higher voltage at 1.47 which doesn't seem right. Is there something else I am supposed to be changing other then that because lowering made it worse not better. I still would have liked to try a higher OC but it seems I am going to have to go even lower then 4.5 to even lower the voltage in which case I would say why did I even bother paying the extra for stage 2 to begin with.

I lowered the Load Line Calibration to high and it took my idle to 1.096 and on full load I was switching from 1.416 and 1.424 so that got a bit better there.

CPU set to Auto

Enhanced Intel Speedster Technology - enabled

Turbo Mode - enabled

Turbo Mode Parameters

Long Duration Power Limit - Auto

Long Duration Maintained - auto

Short Duration Power Limit - Auto

Primary Plane Current Limit - Auto

Additional Turbo Voltage - 0.008


Thank you again Rice

if your v-core doesn't drop you could raise the line load back up to high and reduce the offset.

After you try whats in my last post.

:D thanx man lol

when your comp is under full load is the v-core rising or is it drooping down. So for example when linx is really stressing the comp its sitting right at 1.36 and then rises a bit as load goes down?

Alright so just finished running 10 passes of Linx. I ranged from 1.372 - 1.431. It only stayed up at 1.4 for about 20 seconds or so then it went back down

if normal makes the voltages stay in line a bit more we can play with the offset.


out of curiosity what power supply and model asus motherbaord do you have?

1050 hx psu and motherboard is Asus p8p67 deluxe.

So far I have gone from 1.344 - 1.40 so it is just jumping around a lot still. Don't have anything running except CPUz and hwmonitor

Isn't jumping as much but still is ranges from 1.33 min to 1.40 max according to hwmonitor. On CPUz it still mainly switches from 1.336 - 1.360 mainly but still get spikes

It might just be hwmonitor because I reset it about 4 passes ago and it is now saying 1.33 min and the max being 1.37.

I would probably be fine putting this back on manual since when DS sent me this system it was on manual and the tech had me switch it to offset. I guess my only concern is running it at a constant v core, will that kill the CPU quicker?

Those numbers to set it manual when you say 45 and 47 those would be the ghz numbers I would be changing right? Also with all the changes we made for offset will they need to be reverted back to the way they were if I went back to manual?

Thank you again for your help tonight. I am sure you probably have better things to do but I sure appreciate it.

Edit: I think I found the culprit for the high spikes. It was my Norton 360 which starts background tasks when the pc is idle after X amount of minutes.

Cool I'll give manual a go again. I am going to see if I can keep this offset profile and save a new manual one to the 2nd slot.

Thank you again for your help tonight Rice. They really should pay you guys since we have been at this now for 3 hours.
