same problem here, 2933(100bclk) 2 dimm is easy, 3000(125bclk) can boot up only for 1 dimm.
haven't try 3000(102bclk) yet, will reprot it later

4770k+OC Force(F6i)+Dominator Platinum 2800C12 4Gx4

Those aren't the single sided hynix everyone is messing with, they wont hit over 3K easily, the OC Force doesn't have the same OC ability as the OC either, but the latest BIOS shodul have more tuning, let me work on it a little bit with my 2666C11 hynix kit.. Have you tried the built in memory OC profiles for that kit?

Also be sure to first try with lower CPU speed, on the retail CPUs it seems that CPU speed has a big impact on memory OC.

I would try +0.3v on the SA, AIO and DIO, also if you use a memory profile you will need to input the settings if you manually select a divider.

I've tried the preset profiles as well as manually setting bclk either to 102.3MHz with the 2933 divider or 125MHz with the 2400 divider and setting primary timings. I've gotten it to boot a few times actually but 32M is tough. Main kits are Trident X 2666C11, Dominator Platinum 2800C11 and Vengeance Pro 2400C11 MFR.

Can you try BIOS F5s, this BIOS will set your 3rd timings correctly per what you set in case you are setting those, otherwise try increasing those voltages as well as DRAM voltage.

i know those are double sided hynix CFR, but each of the four sticks can boot into windows 3000Mhz 12-14-14-35@1.72v
will try the memory OC profiles later, thanks for the advice

try loosening up tRAS/using all 4 sticks together! lol that is what helps me with these 4 stick kits, using all 4 together gives me higher results than just 2.

also go under 3D power menu and max out the DRAM power settings, set current to extreme and set the overvoltage level to 250mv or somting simliar(250mv shoudl give you 300mv)

Did you also increase your VSA, AIO, and DIO voltages? those help a lot, especially if you have a retail CPU you need to take the IMC out of the equation the best you can, you do this by lowering CPU frequency, uncore frequency, and then increasing those voltages slowly.

From my testing, the board actually OCes my 4 DIMM its better than when those kits are in 2 DIMM configurations, some timing is most likely different(that is how it is on the OC Force for me at least)

[Shiranui Gen-An]

Didn't realize the OC Force wasn't as powerful as its little brother...

[sin0822]

I am not sure how much less it OCes, i was just messing around with it doing some quick tests with 16GB kits(4x4gb) and tried different BIOSes.

BIOS F5s for the OC board and F6i for the OC Force both greatly tighten the 3rd timings, like GREATLY tighten the 3rd timings, for instance:
F6F just set 29.33 and 1.8v and boot:


F6i just set 29.33 and set 1.8v and boot:


But regardless here are some shots, this one is just auto 29.33x divider with F6i and TridentX 2666C11 double sided hynix, F6F would go further b/c the 3rds are looser:



This is F6f also samsung 2666C10 at 2800 9-12-12-25 T1, this I need to greatly tune, i didn't even change the IMC voltages for this and they were at default when i checked, I just don't have time tonight:


Both need to be tuned more on the OC Force, I mean I need to tune them haha. But I think one thing he might be having issues with is the BCLK, which will be enhanced on the OC Force, however ther eis one issue, the PEX8747 greatly inhibits BCLK OC, so he should use the black bypass if he wants to do over 102-103mhz, also set PCI-E 2.0 mode, b/c there is no 4x PCI-E 2.0 slot (which PCI-E clock is always locked on the lanes from the PCH which it is on the last 4x slot on the OC board)

I am still investigating, but i think the OC was tuned much more than any other GBT Z87 board for OCing, however that doesn't mean the OC Force isn't right now it seems pretty capable(with F6i I notice it also goes through different mem training), its memory OC should still be very strong. I will do more investigating with the hynix kit to help him out.

still no luck boot 2 sticks 3000(125BLCK)，but get 3185Mhz with 1 DIMM
http://valid.canardpc.com/show_oc.php?id=2859696

VCCSA+0.3
AIO、DIO+0.25
DRAM power settings to Max settings

will try 4 sticks tonight

Try 4 i think you might be surprised. Also at first don't use more SA, AIO, and DIO voltages, just leave em on auto. I also use the 8x switch on the CPU, this helps, beucase when you get into windows it is interesting.

Also there is another odd trick i found with the OC Force, this is happens on F6f, if you do something you think wont boot, you just need to interrupt the booting. So if it goes to 15, and then hangs on 15 for a long time, press the power button down until the system shuts off(press it down while it hangs on 15) and then press it again to start up and it will boot. F6i has a different training procedure so this might not work, on f6i you can try 102mhz bCLK and the 29.33

So far DDR3-2933 booting with my samsung @ 1.70V (not fine tune yet).

finally touch 3222.6Mhz CL12 with Hynix CFR

[plane501]

PSC 2400CL8

[sin0822]

nice, what were your results with 4 sticks?

[Shiranui Gen-An]

New 4770K can do at least 4.5GHz without so much voltage it burns up, and run DDR3-2933 at the same time.

Yikes, you did that with Samsung memory?!

[stasio]

Hehe,it's Team 2400C9 with samsung ic.

[plane501]

Hehe,it's Team 2400C9 with samsung ic.

2933CL11 with tight 2nd timing+ tWRWR 4= AIDA64 Write over 45G/S

wow nice CPU there, most retails ai see can't do high memory when at 4.4-5ghz, but that is nice.

BTW in case anyone is interested there are a lot more memory enhancements to come soon, even specifically for PSC. I am also trying to have them change the RTL and IO lat to be fixed instead of offset, right now they are offset of the grayed out value(which changes).

[Shiranui Gen-An]

Man you guys have some strong Team LV Samsung. Mine need 1.80V to boot into Windows at 2933 C12 and not even stable enough to run AIDA64 bandwidth.

I needed 1.85VDIMM so I could run this.

[stasio]

This is with 2933 @ 4.5GHz.........

[sin0822]

This is with 2933 @ 4.5GHz.........

nice, so i guess it must just be noobyness i see over on some other forums lol

[plane501]

Man you guys have some strong Team LV Samsung.

my Samsung @ 2933 CL11 tWRWR=4 need 1.9v

[plane501]

nice, what were your results with 4 sticks?

use 29.33 i got 3050 with 4 sticks....still no good

[stasio]

nice, so i guess it must just be noobyness i see over on some other forums lol

Haha.....don't forget I late at least one month,compare to others (retail).
....and atm I have only one 4770K,so must be carefull not to kill.

Edit:
plane501,
nice one........what is other voltage.....
My XMP is 2400c9,but sticker is 2600c10.
Waiting for 2933 ram next week.

[plane501]

nice one........what is other voltage.....

I leave them @auto

Good news
I can boot with 125bclk 3000 dual channel into windows with F6l

Hi ,

First of all i would like to say many thanks to Master Hicookie !

Here my first shoot under Cascade Cooling -107

Same sticks,2800 from 12-14-14 going down to 11-13-13 @1.66V......
