4790K & 4690K "Devil's Canyon" Overclocking Thread

[Hazzan]

Devil canyon only better on on air cooling or water cooling. but for ln2 result nothing different with Haswell, still very hard looking good chip for ln2 result

@dpa : seem like good cpu waiting ln2 result mate

No need to up VDIMM at all? That's an awesome IMC.

No need for extra SAV voltage its at stock & boots 3000 at stock which I think is quite good. Reckon performance may benefit from some volts with super tight timings & speed but not going to bother pushing this one.

C-N... set the memory back to 2666Mhz and set tWR to 5 then rerun AIDA64

Do you want this for some comparison?

I already know these sticks can do 2933 tWR 5 its just the timings I ran above are my 24/7 settings so not optimized.

No prob to put a screen up in a couple hours if you want it for comparison.

Edit: Screen for the boss

c-n your bandwidth is off, read and copy are way too low.

[C-N]

c-n your bandwidth is off, read and copy are way too low.

What do you make?

I have seen this sort of problem before firstly comparing different versions of AIDA then only using 2 cores..... even opening CPU-Z before running AIDA makes a difference.

Bandwidth looks ok against HiCookie http://img4.imagetitan.com/img.php?image=8_557.jpg

it's because his aida is 3.00,need to run with same aida version to compare results

[Peen]

Looking good guys, my 4790K should be ready for me after work tomorrow.

[C-N]

L418C133 Slightly better than my L148C134

Stock box cooler!! Cache did not want to run 1:1 @ 48 i.e. hanging 32M even with 1.4v

Will give it a spin @ 5G On the 87 OCF tonight

45 45 4/8 Stock Cache


4.8 45 4/8 1.2 Cache

[Gunslinger]

L352C119

Boots and benchable at 4.7GHz on 1.2V - Geekbench and both Cinebench's
Isn't responding to voltage very well though.
Idle temps ~30C on Megahalems with a Delta, load 65 at 1.2

[Splave]

where did you get it gunner?

[Shiranui Gen-An]

Finally got something to show, this is the L418C169 chip. 4.7GHz is doable though my H100i doesn't seem to do a good job keeping it cool.

[Peen]

My chip arrived today. L418C164

Prime and XTU stable so far 4.8ghz 1.348v, uncore 4ghz

Did some benching 5ghz 1.4v

Core temps are a problem though, seeing 23 degree variance in Realtemp. I'm using a custom Swiftech WC system.

[The|Hunter]

c-n your bandwidth is off, read and copy are way too low.

Yeah its because bios mobo sets certain adv 2nd timings too loose, I see the same thing by me @ 2133mhz CL9 vs 2666mhz CL11, 2400mhz CL10 is now ok since bios v1708

Ie proper bandwidth @ 2400mhz, cache 4.2ghz @ 1.135v


cache 4.4ghz test, gained 1points by multi, lost 1point by single..

4.2ghz cache looks the best balance., so far still very pleased with my 1yr old 4770K, I only wished it had 4790k thermals.
Hopefully I can change this with better cooler ie 280L, 6-7C lower temps would look nicer

[C-N]

Not that bothered about my bandwidth it looks ok to me against others me so im happy. If Charles thinks its low show me what it should be & Ill tune for it but in all fairness what I showed is on a stripped 32m xp os & bandwidth is a couple k better with a 24/7 os. I don't see anyone doing much better so I'm happy.

New chip doing better...

[Sniper]

First tests with L3360107 4790K on Asrock Z97M OC Formula, Corsair H100.

[urbanfox]

Everyone is playing with the big boy chips, nothing about the little G3258

Pre-ordered mine almost two weeks ago from Newegg. Originally 6/25, then they pushed it back to 7/1, sigh.

[Peen]

Let us know how that goes when you get it

[Lastviking]

L418C133 looks like a nice batch many on sweclockers got that ones and all looks like doing around 4.9ghz without trouble.

[Peen]

And Lastviking comes in with the old school BH5 sig, love it

I've settled for 4.8ghz 1.35v, 4.4ghz uncore 1.2v, RAM 2600 11-13-13-32 1T for my 24/7 stable clocks.

[Dumo]

L352C118 @ 1.31V h2o, better than most of my 4770Ks

[PolRoger]

L352C118 @ 1.31V h2o, better than most of my 4770Ks

Stronger than my L329Cxxx batch which BSOD at 49x with ~1.3v (48x is benchable though).

I'm kind of curious... How much Cache voltage to bench with uncore/NB at 48x?

[l0ud_sil3nc3]

L418C169

Default VID on the Z87 OC Formula is 1.208v

no waza so it will need a bit more voltage with waza, but definitely promising, now it just has to scale with cold.

[Shiranui Gen-An]

L418C169

Default VID on the Z87 OC Formula is 1.208v

Same Batch # L418C169, not quite as strong.

[Shiranui Gen-An]

Different batch on a different board, L331C501 on Asrock Z87 OC Formula. This one looks promising.

[asfgbdnf]

Nice chip, are you able to pass wprime 32M @5G with this voltage?
