yeah tried load up the PSC 2400 1.65v preset, LinX failed to proceed for the 2nd loop.
Bumping up vdimm, VCCSA, VCCIO, VTTDDR, loosening tRDRD etc don't help even at 2T.

I'd say the importance of core > uncore = memory

So, either one first should be fine.

The Uncore speed affects the speed of the L3 cache which will benefits some memory intensive benchmarks.
L3 cache is designed for the memory subsystem in machines these days for latency compensation.

Uncore 3.9GHz:


Uncore 4.5GHz:

Retail MVIE

BCLK 200.7MHz:




Memory OC 3086MHz:

^ side note is LinX generates more heat than Prime95.

4.6GHz 1.325v LinX is as hot as 4.6GHz 1.44v Prime95

The latest BIOS 0031 is amazing. Hynix BFR is now working great and finally overclockable.

Bought myself the ASRock OC Formula Z87 from hikari85. Very powerful, fast boot, brilliant BIOS; yet worth the money.



Saw a lot of extreme crunchers playing with Samsung based RAM kits on this board so I'm not excluded.

G.Skill TridentX 2666C10 @ 2800 9-12-12-25-1T


Team Xtreme 2600C10 @ 2800 9-12-12-25-1T

Give it 2v+ it's not gonna kill these baddass.
Remember old timer Reaper rated 2.2v?

Samsung scales well with voltage.
2.25v on air is possible.
Not for 24/7 of course I hope everybody can understand that.

Impressive. Obviously it is a BIOS issue since Z77 I couldn't run the same kit at rated specs even at 2T. That's why I said 0031 is amazing.
As for OCF, I think nickshih's reply is not satisfying because the same kit worked on MVIE at 1T without any issue and no insane overvolting has been done.
Something wrong with the BIOS for sure.

Nice
Now everybody is playing with Samsung @ 2800+ 9-12-12.
Would you try that on your Z87-OC?

It is okay bro don't worry RAM is durable and life-time warranty
I've never killed a RAM, except for one module of RipjawsZ 2400C9 which was running at stock 1.65v.

PSC on OCF

2400 7-11-7


2600 8-12-8

Can't recall but should be 2800 onwards needing me to up tRDRD to 5.
I don't have any CPU to play with right now waiting for Costa batch lol.

Looks like bro you need CFR/MFR/Samsung for 2800+
wahh just noticed there are a lot of new 2800 kits listed in newegg.

Still waiting for nickshih to fix the 1T bug on CFR.





MC this whole week so will be free to test that little beast LOL

Posting on behalf of my best friend kelvinchen

Team Xtreme 2666C11 2X4GB MFR @ 3250MHz 12-15-15-1T



This shows the power of MFR on Haswell.

According to kelvinchen master the vdimm is not more than 1.9v. The damage is $300 usd (market $150).

Hynix ICs are separated to 3 common chips, which are BFR (cstkl1's kit), CFR (owikh84's kit) and MFR (kelvinchen's).

Normally MFR has tRFC > 300 and can go 3000+ with no sweat. The best MFR atm is tge GSkill 2933c12 kit which is able to do 3400+ C12 on air.

ASUS Maximus VI Impact in the house...



Review is coming soon. Stay tuned.

Not mine...

Limited and unreleased PSC based 2600 C8

Weird by rights, the i5 4670 turbo clock is supposed to be 3.8GHz.
Enabling MCE will make all cores running at 3.8GHz under load.
What's your max temp during load? Did you hit 100C? Update your bios already?
A screenshot of RealTemp and CPU-Z will be helpful.

Can't predict how much is the SRP for M6I in Malaysia but should be slightly more expensive than Hero.
FYI, initially M6E SRP was expected to be sold at RM1499 but later ASUS MY decided to slash our heads for RM1818.
If you feel that 4.0GHz is still slow then why not matching his clock @ 4.3GHz?
All Haswell chips can do this very easy, provided your cooling is able to handle the heat.
