New topic : low oc temp 4670k@4.5(60c on latest p95), and low gflops on IBT

chromic · Sep 17, 2014

1st time OC'ing (and owning) an intel based system.

Its seems so much more complicated than AMD..
Here is an amd oc guide :
turn off powersave stuff, turbo etc.
set digital voltage settings.
then simply increase voltage & multi.
stress test..etc..

Now to intel...Cache ratio, cpu ring freq, CPU input voltage, i dont understand 1 bit of these.

Scroll to bottom for new topic.

4670k + MSI Z97 GAMING 5

don't need all that ring bus and stuff like that.

just up multie and vcore manual and that's it, depends how high you want to go.

TheGoat Eater · Sep 17, 2014

yep, all you really need to do is to increase the core voltage and up the multi... It is very simple, though the bios can be intimidating for sure sometimes

chromic · Sep 18, 2014

what about digital power options? LLC..etc?

mastergup · Sep 18, 2014

depends you have to try it, my I can leave at auto with no problem.
my settings for 4.7ghz are cpu current capability at 120% and power phase control optimized.
multi 47 and vcore 1.255v
cpu cache ratio 4.2 and 1.2v
rest is auto.

Did a quick test 4.5ghz @ 1.24v (cpu-z 1.264v)

P95(28.5) smallfft temperatures max :
1core 60c
2core 60c
3core 63c
4core 59c

delidded, mx4 on "every" gap.

Info: Clean win7Ult. installation with 0 drivers/updates

only g.chrome/cpu-z/prime95/IBT/hwmonitor

IBT gflops were only 48 tho...@4.4

mastergup · Sep 18, 2014

What kind of cooler you have, because that's a very good temp for that vcore using the new prime95 , I never use prime for haswell, its not the best stress test.
even with my cpu at 4.5ghz with only 1.170v I go way higher but my is not delidded.

Antec h2o 1250 AIO cooler (about same/few degrees better than H100i)

mastergup · Sep 18, 2014

how long did you test then????
because the new prime95 jumps right into the 90,s what I have seen.

chromic · Sep 18, 2014

around ~10 mins, temperature jumps straight to 55c and starts to increase veeery slowly after that.

mastergup · Sep 18, 2014

that's nice then, and with itb????

but the gflps I don't now, it should be higher even at standard settings.

chromic · Sep 18, 2014

~5c lower (53-57 cores)

Ill download and update drivers and test again later

chromic · Sep 18, 2014

cinebench 15 is quite normal score...666

chromic · Sep 18, 2014

Now ive noticed why its so low, SP1 package was missing in windows.
downloaded & installed.
Temps are now :

P95 smallfft ~75c max
IBT 68-70c ~105 Gflops
Linx 0.65 +~120 Gflops

mastergup · Sep 19, 2014

hahaha yes service pack 1 is necessary.
but still very good temps

chromic · Sep 19, 2014

with mx4 paste.

Liq. ultra arriving today i think.
will re-post temperatures after that.

mastergup · Sep 19, 2014

oke, but why do you need that stuff, are you a somebody how whant to clock as high as possible.
its not good stuff to remove.
it is already cool enough as it is right now, so why do you need it.
