Have you had to tweak IO and SA voltages much Virus?
Click to expand...

not much no, i just bumped them up without testing if they need bumped or not, but its generally important to bump those up if you are overclocking your memory to gain stabilization.

so without testing i just bumped them up when i went from 47x to 48x on the uncore, figured it cant hurt :) lol
 
1.18 here on IOA/D and SA when i clocked my 4770k, (4.5ghz) and my first 4790k. The latter chip was benched at 4.8 on 1.3200v but not game stable. 0x124 bsods, i had input voltage at 1.88 so this may have been a cause. I cant test with p95 etc due to temps getting too high.

Vrin/input voltage is the key with haswell.....
if i had also known this with my previous 4700k i would have gotten it higher to :D
 
Testing GPU overclocking-
Crysis 3 - 1 hour 30 minutes - 1150/1650 1 single slot card 62/66 temps. :)

--------------------------------
@ 4.8ghz 4.8ghz uncore - STABLE.

Thought i would post some system pictures i took today
though i need to get the dust buster out lol, also took pictures of my rad at the back side of the case using as external :D
its pretty effective for me and its right beside the window as well cant wait for the pure winter to kick in hehe :D

--Warning pictures are pretty big you might need to resize them *samsung galaxy s5*

Well i got 4.9 stable as a rock with 4.8 uncore.
but the heat is starting to get to my watercooling system lol, and the voltage i dont think i would be happy with it running 24/7 @ these voltages even though its rock solid

but its taken 1.350v to get to 4.9ghz stable with a 0.03+ voltage variance between loads.
low 80s aswell thats pretty good as no other stuff will get as high as that apart from prime95 new version... add +3-5c onto those temps and you get the prime95 AVX results, stil well within safe temps but anyway , just to show you guys im full stable @4.9C/4.8U

Even though i am running my fans at silent speeds i could probably get under 80c with them cranked up a little more but i like silent :D
 
Yes like it, It`s great when you get the 1000 mark on cinebench. your volts are a bit on the high side, was your DC a L42 if so you should find they can do higher clocks on lower volts and do find that F7 bios stable. You must be a happy man now virus2k.
 
My 4790K overclocks to 4.7ghz with 1.24vc it will run cinebench/realbench. Where it falls short (for me) is requiring approx +0.040 (1.28~vc) in order to be stable for Handbrake.

Just don't think 4.8 going to happen with this chip due to temps, and just don't want to delid.

Can be stable for cinebench, real bench, aida, but bf4 requires me to add a lot to vrin and up the vcore to around 1.37v

Those levels just start to push it above what I am happy with voltage and temp wise.

Aida a no go at the settings required for bf4 to be stable.

Very ;)
though i cant make my mind up 4.9 24/7 or 4.8 24/7 lol
 
decided on 4.8.4.8 uncore with a variable voltage offset fix instead of static :)
now voltages are read correctly in windows and cpuz ;) could go 4.9 stable though whats the point lol anyway i have that choice if needed.

1.320v under IBT
1.344v under avx prime95 new version
0.0120 set in bios ;)
bios voltage reading 1.318v
-------------------------------------------------

Some strange reason you gain slightly better temps with offset instead of static/ variable between 2-4c lol or that could be a placebo and i am seeing things :)
----

dont know why i am doing all this testing and stuff when im a gamer haha
and will probably be going x99 anyway though i can point someone to this thread when i go to sell my z97board and ram and cpu ;)
