***Offical ASRock z97 OC Formula Thread - Tips / Discussion / BIOS / Tools***

[Anusha]

How good is the Z97M OCF? Anyone got a chance to try it out yet? I cannot find any reviews on the darn motherboard.

For some reason, there aren't a lot of reviews on Z97 boards this time around. Perhaps because a new generation of CPUs weren't released with it.

Holy Grail IMC!

For all the naysayers, it's always been about IMC strength and this further strengthens all evidence that ic quality is equally important as the former.

My 2400 c8's have never been able to do this, EVER and on this chip I can loop 32M, with waza all day. Prime candidate for 2800 c6 I think.

vdimm was set at 1.92v in bios

Nice chip loud,nice time too

Thanks bully

Retested the first G3258 on W7 this time, and dat yellow board efficiency

Before buying the motherboard Asrock Z97 OC Formula, I need a piece of information.

I have just read the manual and it is said that PCI-Express slots 1 and 2 must be used for 2 graphic cards. But page 19, I quote : "PCIE4 (PCIe 3.0 x16 slot) is used for PCI Express x8 lane width graphics cards"

Since the PCI Express 4 slot supports x8 lanes, can the 2nd graphic card be inserted in the PCIE4 slot ? In this case, does it work at x8 ?

It is important for me since I am watercooling 2 290X cards and the PCIE2 slot will be too close from the PCIE1 slot.

[Luumi]

Yeah, you should be fine overclock. I like the asrock z97 board, just need to find better efficiency and get higher mem and 6m can be passed.

Damn,i always tought your mems are stellar bin and should do better than 2666,seems like finding a good imc for psc and bbse on haswell is about as tought as finding a great core....

you can use PCIE 1 and 4 ..... it is fine

then it will be x8 and x8 . So it is no problem support 2 x 290.

Z97 M OCF is capable of memory overclocking also .

I have implemented bios tweaking . It is 4 layer PCB design

It is good enough to do every kind of benchmark on aircooling .

For sure . Z97 OCF perform much better at extreme overclocking .

Played around with G3258 the other day, pretty fun for $70! Board is very efficient of course












Comparison, chip speed to score. Score seems nice and high for the clocks.



Oh and 01 isnt bad either legacy tweak enabled and card on air!

[bullant]

Nice Splave,the board is awesome 3D and 2D super efficient, just waiting on a couple of those Pentium myself and a new 4790k to try then should be able to post some more myself

[aerotracks]

Anyone else having trouble getting TWRWRDR to post (consistently) below 8? I'm seeing this with the two Samsung kits I've got, CMD8GX3M2A2133C9 and CMD16GX3M4A2666C10.

[Splave]

what voltage?

[aerotracks]

Between 1.85 and 1.65V, that's all I tried. Feels like erratic behavior - most times it'll give me an 'overclocking failed' repeatedly. I can make it post by switching back and forth between tWRWR_dr 8 and 4 and but again it will fail after a few reboots without having changed any settings.

Edit: Did this yesterday. Took me a few tries to post tWRWR_dr 4 before running 32m. Right now all I can to is load that very profile set tWRWR_dr 8 and then boot up.

[Punk Sods]

Hi there!

After a few years, just read along here I am also registered here.

The Z97 is now my third mainboard out of line and I'm very happy with it.

@ aerotracks
So we meet again.

Hey guys i know that the Z97M aint for LN2, i still didnt test it, anyone did on water cooled CPU and see how it clocks CPU and MEM ?

Cheers and Congrats for the AWESOME RESULTS

I would try again with your 2666 C10 kit & more SAV, IOA, IOD volts. Have you tested with these values at auto?

[aerotracks]

Raised those values as well as setting them on auto - sometimes it'll post, most times 'overclocking failed'.

[C-N]

Tested tRDWR + dd + dr to 13?

[aerotracks]

Let me check that out. Thanks for helping

Edit: Nope, 13s with tWRWR_dr 4 failed too.

[Splave]

try 1.98vDimm

[Punk Sods]

IMC test with a G3258, 4000 Mhz Core - 4000 MHz Cache, 2x 4GB G.Skill F3-TridentX 2400C9Q-16GTXD. The CPU is water cooled, Ram Air Cooled.

[Splave]

imcs are on average very nice on those CPUs isnt it

[bullant]

Stability testing some PSC cl7 twcl8 fairly tight subs,memory on air 1.89v,was also nearly passing 2740Mhz
CPU used is my gem chip with wounded imc, waiting on new chip to arrive next week

[Punk Sods]

imcs are on average very nice on those CPUs isnt it

Just average, oh.....

I want to try to get a little higher with the CPU clock, unfortunately the Pentiums are require a relatively high Vcore. There is currently very warm here (up to 35 Degrees outside), so I have to wait a bit longer.
