btw i bought the 2.4C9 BFR from owikh.

Now must get some samsungs and mfrs.

samsung 2666 C10 seems hard to get.

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

Your ram voltage at 1.864v?

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

I see. Only samsung-based RAM kits, high-performance kits or DDR3 in general?

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

2.25v!!?! Wow! Nice!

My rams rated 1.60v 2133mhz and I don't dare go above it.....

According to nickshih,
hynix bfr/cfr double sided sticks is impossible to do 1t on z87 ... It is platform limitation .
I still keep my bbse 8-9-8 and one more 2x4GB ripjaws 9-11-10 (samsung ic).

Did u see owikh running 1t up to 2600 on 4 sticks of bfr.

Hmm,maybe atm on the ASRock......

Btw,fast test.....4.5.......

nice

but here is a hint
linx/intel burn test will accept 0.05v to 0.1v less. but not prime
ure realy vcore up to 44 is the same as ure uncore..

meaning try running ure vcore and uncore at 44 both at the same voltage.

thats ure vcore. after that uncore gets tricky but vcore still can scale

btw i found the issue. running 2.4k C9 1T now.

No way u can do this on any other board. Sham RTL guide and bios 031.
Although it was a bit off... 4x4gb is different...

4.5.......LinX 10.3.12......fast test (still not trimmed)



IBT.......

@cstkl1,

Since you had killed so many proc , mind telling me the vcore when the proc died? You were saying that they died when vcore was low right?

What was the reasons they died or in other words, what not to do when overclocking Haswell?

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.

all low. 1.2-1.25v. procs died because of mem. I think those procs were weak. current proc has reached 78 code before a few times but will bounce back on full bios restart.

hmm its the rtl and the difference with the new hynix profile and auto is also rtl. new hynix its lower. my the 2t=1t in auto.

Me loving the rtl again.

yeah his answers are one liners and so far on the wrong assumption.

Yea,sure will try later.
This is with 2933 @ 4.5GHz.........

I see.... will try OCing the rams one day then.....

That low huh? I suppose you mean weak because of the weak IMC?

Nice . Are you using adaptive or override for CPU voltages? I can't seem to get C-states on override on my ASROCK....
