Prime95 error-rounding was 0.5 expected less than 0.4

[Alex19961130]

hey I've been trying to achieve stability with my computer for awhile now, it usually passes with intel burn test for 20 runs with the maximum setting but only lasts 2-4 hours in prime. now my temps for my CPU never go above 55c, iv disabled turbo boost and locked my CPU at 3.5GHz.My ram is running on the xmp1 profile, and i set the ram vlotage to 1.65. my cpu vcore is 1.70. any help would be greatly appreciated

increase cpu voltage by 0.005V? try not using the xmp1 profile for memory as this might be forcing an overclock on the memory controller depending on what cpu you have (it'd be handy to know this)

but doesn't 1.75 vcore seem unreasonable for 3.5GHz? and i use the xmp1 profile because it also automatically sets my timing which i don't really know how to do

You vcore is 1.7? I can't think of any modern CPUs that would like such a high number. Sounds like your Vcore is much to high, but without any system info its just a guess.

and still you have not told us 3.5Ghz on what system...

What test were you running on Prime95?

sorry i meant 1.375

i5 2500k with a z68 motherboard

right then 1.65V on memory is too high, 1.75vcore is too high. your chip might already be nearly dead.

set it to default and make sure it is stable at stock. Tell us what happens.

vcore is 1.375 and online everyone says 1.65 is max safe voltage
also even at stock it its not stable, after i upgraded to uefi bios it was stable for a few days then adter i change some basic stuff i starts failing prime 95...

 

[13thmonkey]

well stock memory for i5 2500k is 1.5V 1333Mhz, anything more than that is OC, is it stable like that? Try stock everything.

ok i will ill let you know what happened tommorow

ok, so i ran prime 95 last night (about 9 hours) with ram at 1333Mhz at 1.5 volts and cpu at 3.3GHz with turbo boost disabled and vcore at 1.375. two cores past but the other two were off with no error code. then i bumped up the vcore to 1.380 and ran it for the day while i was at school (about 8 hours) and three cores past and the last one had the rounding error. so tonight i guess ill try with 1.385... i guess my chip wont be a good overclocker if it needs this much voltage stock

Why are you bumping up the Vcore if you got no errors?

because two of them weren't running when i enabled them all

I'm sorry. I thought when 13thmonkey said to run it at stock you were. Can it run with everything at stock? Put everything, including core count at stock. Does it work? For all we know you have a bad core on your CPU.

you mean put vcore and ram voltage to stock? itll fail then, i tried it before. and btw i probably should of mentioned this before but i took my computer into a shop to make sure nothing was defective and they said everything was in good shape

 

[4745454b]

I meant put everything at stock. Voltages, speeds/frequencies, timings, etc. If it doesn't work at stock you have issues.

they said everything was in good shape

Did they even test it? You said there were issues.
