Hi, does anyone here have experience OCing on Intel DZ77GA-70K? Might be getting a 3770K + mobo + SSD combo as replacement for my trusty Conroe system. I'm hoping it's at least good enough to get the proc up to a range of 4.4~4.6GHz

Sad I have to buy 3 items together as a package. Oh well, never mind I guess... Shall be the first here to OC with Intel mobo

May I join? Just finished setting up my Ivy system last night.

Adjusted the multiplier to x45, LLC to high, HT to off, everything else on stock. And I can bet I'm the only one here with an OCed i7 on Intel-branded mobo

You mean should turn on HT? Because I read from OC guide somewhere to turn off HT

Now 2 hours liao and still running strong, gonna try with 4/8 cores afterwards. Surprised that the temps are around 80, I'm just using Hyper 212 Evo and not some big hsf or wc...

Added on August 1, 2012, 11:07 pmWeird. I turned on HT but GFlops dropped to ~60 only Must be something wrong somewhere, or is it due to my RAMs?

IBT gave ~99GFlops but LinX only ~62GFlops. I thought they are essentially the same, but why 40GFlops gone with LinX

Thanks for the tips and advices, now my LinX also can peak at ~100GFlops Tried 4.6GHz just now, but BSOD after 30mins

Nothing magical I'm afraid ... Just downloaded the latest LinX version s provided by stasio

4.738GHz with +60mV to Core Voltage... 4.6GHz needed +40mV to remain stable while 4.8GHz +100mV (but no go as temperatures reached TJ Max within minutes ). So this is obviously the sweet spot, still amazed at how well CM Hyper 212 EVO performs despite costing a reasonable RM107

Thanks Mine is batch 3219B951, I guess chips around 32xx clocks quite well

Made a few tweaks to my 4.5GHz OC:
1) LLC dropped from High to Low (for lower VCORE under load as my board doesn't support under-volting )
2) BCLK returned to stock (was causing random issues when waking up from S3/S4/S5 state)
3) RAM upped from 1600MHz to 1866MHz (Trying to learn about timings, but those sub-timings are driving me )

For 4.5GHz you're gonna need a new cooler... The stock HSF is simply too "thin" for the job But still, nice clocks for 1st attempt

For RAM, is it better to go with high clocks or tight timings? And is 1.65v considered a safe (because my G.Skill default is 1.35v only )? Applied 1.5v for 1866MHz atm and can't seem go higher without extra juice...

Nice! Gonna try with 1.65v later, now downloading anime What about System Agent Voltage (VCCSA)? This one inside processor, worry a bit...

Thanks! Have been looking for a guide like this which teaches how to calculate/set appropriate values

You guys dare set so high for VCCSA? In post #1 stated max is 0.971v nia But what I find weird is when using Intel's own OC Assidtant for RAM overclocking, the BIOS will auto increase VCCSA to 1.050v, don't Intel know their own spec

Today's attempt: 4.8GHz

But temperature is close to kissing tjmax in an air-conditioned room

Gonna try tonight... Full RAM selected takes a long time for 1 loop and I was already in "sleep" mode, lazy to wait

That CLU TIM (not interested in removing IHS ) seems quite interesting, price is not cheap though.

Re-stressed with more RAM used, seems stable and not much changes in temps.

You have TEC which moves heat away at an exceptional fast rate, so the improvements a good TIM like CLU can bring for you is definitely significant. Me... Air cooling with a lowly Hyper 212 EVO, maybe 5 degrees at most

Already quad-TEC still wanna upgrade summore, and fuh... 12x Typhoons

Hmm... I wonder if H100 will do for 5GHz. Customs are a little too costly for me (although I did consider them once before ), and H100 is way easier to install

Seems like most air coolers perform more or less the same, apart from D14 But never really like big fat coolers, hard to swap RAMs (although I don't do that much )

Hmm... RS240, with compression fittings it'll come to roughly RM600.

Yo, anybody know where/who got sell Samsung Green DDR3 (30nm LP)? I found a few sellers on eBay, but shipping will take quite some time

Wanna try OCing RAM to at least 2133MHz but my G.Skills are kinda limited.
