Re: Haswell Overclocking Guides / Results

Finally Stasio joins the club, about time man....

What ram was that? Team Xtreeem in your sig?

Re: Haswell Overclocking Guides / Results

And the question now is how high can Stasio overclock his cpu with his current 2800MHz memory speed?
Inquiring minds want to know!

so folks is haswell a yay or a nay??

im waiting for skylake

Re: Haswell Overclocking Guides / Results

I am all for haswell. Using ConvertXtoDVD I would say a movie that would take to about 5-10 min is now about 3-5 min. But ivy was at 4.5ghz while haswell is 4.7ghz. Still its all luck of the draw. I could drop in my 4670k and see how I can do on that again now that I know how to overclock a good cpu. Also I never put liquid pro on the cores of the 4670k so I might do better but I doubt it will do anything like my 4770k.

Re: Haswell Overclocking Guides / Results

you need liquid pro on there

I saw 0 difference on ivy with mx4,when I used liquid pro I saw 20c drop,i still don't go over 80c @4.8ghz

Just FYI your pc specs show "i5 4770K".

You guys got all the overclocking figured out and here I sit still waiting to get my new board and cpu. My main rig components are all packed up ready to send out but I have bought some replacement 840 SSD's and another pair of 7950's.
My backup rig is OK, I just miss my "hotrod" with the new tech.

Re: Haswell Overclocking Guides / Results

Ace, sorry to hear that your 4770K's performance is at the i5 level.

Has anyone with a 4700K enabled Hyper Threading with a modest overclock to see how much it raises cpu core temps?
An early Haswell write up said that temps could be 8^o - 10^o (C) higher with HT enabled.

Doesn't it come with HT automatically enabled?

Re: Haswell Overclocking Guides / Results

HT might default to being enabled, but there should be an option to disable it, but only with processors that support HT. With a cpu that doesn't support HT, the HT bios setting will be missing or it will be grayed out and not modifiable.

Re: Haswell Overclocking Guides / Results

Not sure for a 4700k didn't know they made such a beast. As for disabling HT and what temp, Vcore drop you get not sure. I think I tried to disable HT and saw 0 improvement but I was still learning (not that I have finished learning) how to overclock haswell. I could try again since I need to retest settings for new bios came out. A lot has changed since the first "i" series cpus (socket 1366).

Yea......late for a month.......
Yes,team...atm
getting G.Skill 2933 soon...(paid)

Re: Haswell Overclocking Guides / Results

Disabling HT on my 4770k so far with LinX did not try others seems pointless. little to no temp drop and vcore I was able to drop from 1.21v to 1.20v

Re: Haswell Overclocking Guides / Results

Has anyone tried LinX with the newest Linpack (11.0.5.009) on default settings? I get the same crash after one rep that I do with an OC'd rig.

Linpack 11.0.5.009 does make it through when I use the Linpack sample script, but then it stops using 2 cores during the middle of the run, with lower Gflops -- around 100 or so. When I run LinX + Linpack 11, during the single run it does work, it uses all 8 threads at 160 GFlops.

What am I doing wrong?

[ehume]

Re: Haswell Overclocking Guides / Results

Based on some advice, I disabled HT, then ran Linpack 11.0.5.009 from its batch file. LinX with Linpack 11.0.5.009 has been crashing after 1 rep, and that is why I went with the batch file. For now, CPU is at default. Here are the results:

188-189 Gflops is much more than I expected to see.
