Just got 2500k to 4.5

[dan2222]

Ok i just got my to 4.5 but after 6 hours of running prime, worker got 1 error saying FATAL ERROR rounding was 0.5 expected less than 0.4.

Can anyone let me know what this means please.

need slightly more vcore...what volts you running?

 

[dan2222]

Ok firstly this is my first ever build and first time overclocking, just thought id let you know that in case i say stupid things.

Ok i used 1.135 for 4.5ghz

 

[deletedcod]

lol you can safely go up to 1.35v for 4.5 roughly between 1.25 to 1.3v put it on 1.2v and stress again ill assume you have a aftermarket cooler?? or do you have stock cooler??if stock dont go higher that 1.25 volts max and 4.2 most people go higher on stock but they know what they looking for but just to be save dont (imo)

 

[dan2222]

I have a coolermsater 212 hyper plus. Did u say i should go down to 1.2v for 4.5

 

[deletedcod]

no down up to 1.20 to 1.25 some cpu's need 1.30v for 4.5ghz all's not the same

 

[deletedcod]

but 1st set it to 1.20

 

[dan2222]

Ok so basically go down to 1.200v and see if it boots and runs prime and then work my way up if it does not work

 

[deletedcod]

yip thats correct

 

[dan2222]

Ok quick question, i have it at 4.5 on 1.300v now and i keep getting an error for worker 3, i tried the large ftt test or what ever and the blend test and each time i get an error in worker 3

 

[deletedcod]

you do know that you can get errors for to much volts to...do you have a app to monitor all you other volts?? like pll vccio etc??? what voltages are your othe stuff at? auto??
and it's possible that some cpus need more than 1.3v to get stable @ 4.5ghz put it on 1.25 and try again never rush it lol work your way up
if you want to OC you gonna need alot of patience

My 2500K takes 1.325v @ 4.5ghz

 

[dan2222]

No i dont have app for volts. At first i followed a bit tech guide for my board and 2500k to go straight to 4.8, so i made changes to loads of things that they said like system agent voltage and loads of other stuff. Now i just have everything on auto and just changed multiplyer and volts.

One thing that was strange with the bit tech guide was that it told me to change something to ahci or something but it wouldnt boot, so i left it as ide and it worked

 

[dan2222]

Sorry 4ryan6 just see your post, i think mine needs something like that too. Should i be doing anything with my memory, it g skill rip jawsx 1600 or should i just leave it alone.

 

[deletedcod]

oh something i gorgot to mention what is your vdroop setting at not sure what it is on your board...mine shows in % from 50 to 100% some shows different

 

[deletedcod]

leave you memory for now...are use ryans volts and test from there if you happy try lowering the volts till you bsod thing with oc u want to find the lowest voltage for highest oc im showing you the bottom end up or you can go from high to low

 

[dan2222]

No im cool doing the bottom end up way lol, i just looked for vdroop but cant find it and dont know what it is

 

[dan2222]

The error i keep getting is a rounding error which i just reat is something to do with ram, is this correct

 

[deletedcod]

what test you doing on prime?? small fft? or blend??
your ram should be at defalut did you change anything there??
what mobo do you have again???
vdroop is eg when your cpu is underload the voltage drops like if you set it to 1.3v when vdroop kicks in it will be eg 1.25v making ur oc unstable so what ppl would do is put vdroop at maximum depending on oc so the volts dont drop to low to keep oc stable....so idle would be your volts would be what you set in bios 1.25 underload it will be 1.20 so if you cant find your vdroop setting up your volts till you find ur cpu stable,if i was you i's reset my bios and start over,dont touch anything else but your multi and volts when needed,if you find your vdroop settings even better set it to maximum for now

 

[deletedcod]

and use small fft for now to just test ur cpu and please get some monitoring apps...hw monitor is a good free app get it

 

[dan2222]

Ok my board is gigabyte p67 ud4 b3. there is an option that says load optimized defaults, is that what i should select

 

[deletedcod]

YEP thats puts all settings to default

 

[deletedcod]

on google it says that setting is called v-drop???

 

[dan2222]

Ok the only thing i found was 'load line calibration' which says if enabled it will improve vdroop. The interesting thing is that when i enable this, im able to get 4.5 with much lower voltage than when its not enabled

 

[deletedcod]

But is it stable with lower voltage?
