Afternoon pack,

About at the point where I run out of ideas and come for some advise!

I picked up 4 x 4GB of that HyperX Beast 2400mhz C11-13-13-30-2T, running 2 x 4GB is fine, throw in the other two sticks and things start going south.

4x4GB gives me BSOD's galore, no particular one error springs to mind, I must have had 5+ BSOD codes in the space of an afternoon.

4x4GB fails memtest hard with 20+ errors.

2x4GB - both kits - run flawlessly alone and pass memtest without a single error.

SO the dimms are perfectly fine.

Must be the motherboard or me?

I've set DRAM voltage to 1.7v, SA/IOA/IOD/PCH all to 1.2v no joy, still errors.

Currently working my way through bios revisions to see if thats the problem, even though the kits are listed on Gigas QVL.

F06 - Boots into XMP fine, BSODs and memtest fail
X02 - Fails to post, on anything other then 1333C9
X07 - Fails to post on anything other then 1333C9
F08 - just about to flash now and will report back

At the moment its looking like yet another absolute top notch gigabyte board, ruined by some small problem.

Googling around suggests the problem is not just limited to the OC but other giga boards on Z87 suffer the safe fate with 4 dimms.
 
Didn't realise x08 was out will try that too, f08 is out of the window just now, @BIOS doesn't want to install.

Have around 6 kits now :p

Will try at 1.25v too though its a little drastic just to get xmp speed and timings running.
 
Ahh app center may be what I'm missing!!

Just letting memtest finish up on f07 and I'll give it whirl thanks ;)

Edit: F07 still bringing up the odd memtest error with all ram banks populated.

Sigh.

Ok APP center installed, is there anyway to tell what version of @BIOS comes with it? As I installed latest from gigabyte UK, then it asked me to update, so updated that and the above linked @BIOS still just opens install shield, then closes its self inside a few seconds. The only change is it now asks to close app center before it closes its self :confused:

dot net 4+ is installed.

Win 8.1 update 1 x64

Edit: nvm, hold mouse over @BIOS icon reveals it is the version mentioned above! :)

Ah well was worth a shot. To break down bioses so far:

F06 - BSODs & ~20 memtest errors
F07 - Single BSOD & 2 memtest errors
F08 - FAILED POST @ XMP, 1.7v, 1.2/1.2/1.2v
X02 - As above
X07 - As above

Do I have grounds for RMA on this as the memory IS on the QVL yet refuses to work with all banks populated?
 
May be a point, running memtest now on profile 2 (2133c11) and everything's coming back clean.

Guess I'd taken my IMC for granted as with 2 sticks I've had no problem running 2400c7 & 2933c12.

First time I've used 4 sticks since 775 & ddr2:p
 
I'm still going to do some testing as it makes no sense that F06/7 will post fine at 2400 and occasional BSOD, but F08 flat out refuses even if I manually slacken the timings out to 12-14-14

Edit: x08 ain't happening, the new qflash is stopping it as the bios is older then f8. Magic.

Edit 2: F8 is complete junk, it posted and checked out in memtest fine at 2133, untill I checked the timings it managed to post at...11-15-15!! The timing range probably doesn't go high enough to let it post at 2400 :p

Back onto the other bios switch to F06.

Now firing out errors at 1333, 1600 & 2133 while all populated. I'm out, done, whatever, memory is going back/MM its a hassle I can do without. Starting to think it might not actually be on the QVL, as it lists KHX24C11T3K2/16X not the KHX24C11T3K2/8X kits I have.

Either way, lesson learned, stop buying gigabyte motherboards and kingston ram. Asus and Gskill only from here on in.

Final test of any chance of stability was:

1600
9-9-9-24-2T
DRV = 1.7v
SA = 1.25v
IOA = 1.25v
IOD = 1.25v
PCH = 1.25v
PCH IO = 1.8v

CPU at stock, still fires up 20+ errors on memtest.


And to top it off, what ever this ram has done to my system I now need to re-install windows as it takes about 10 mins to log in regardless of what ram is in and what slots are populated.

Paul, if you want a shot of another board or another set of ram just let me know, i can easy drop some off or let you pick some up. (Kingswells).

Shouldn't need that much SA/IOA/IOD btw….In fact everything should be on auto for running cpu/mem at stock/xmp.

Not a great idea running 2 kits of 8gb to get 16gb.

Top tip, get a second ssd/hdd with fresh install for playing about with ram, likely hood of corrupting os whilst tweaking is quite high.

Sounds very helpful Doug, are you on steam/origin? If so add me (pgi947) and we can talk further :)
 
Will get them up as soon as I get home from work (on my day off too!!!!).

I didn't go as far as checking seconds and thirds, just primaries and trfc which iirc was around 216.
 
Urgh FML.

Now refusing to post at 2400!!

Strangely enough, my bios is now reporting to be F03, I could swear it was F06 yesterday :confused:

maybe trying system performance enhance on standard might help,that setting tightens/loosens 2nd/3rd timings

I just tried this out of interest, setting the highest profile 'extreme' gives me a 4.7ghz CPU clock and sticks the ram at 2133 9-14-14-36-171-2T

Sounds like you've got different ICs to me if you need over 200 tRFC :S
Click to expand...

I had looked into this, both kits report the same manufacturing year/month so I would presume they are all the same IC.
 
Ahh sorry I misread your post :p

God knows whats happening now, regardless of bios it now refuses to post at 2400mhz with ANY timings.

@Pack, XMP reported 2400 profile (managed to get that by flicking to F8) for tRFC is 192 and tREFI is reported to be at 9400.

Does this board have an option for OC re-try? If it fails to post once it just says OC failed and go's back to default, iirc on my MSI X79 board you could set re-try count and force full start up memory training.
 
Cheers roff I just tried those, even then flat 15 timings won't post.

Something's not happening as it should at 2400mhz, at 2133 its letting me tighten up like crazy without adding volts to anything yet 2400 won't post with pointlessly slack timings and silly volts :(

Edit: also no option at all to change CR on this:confused:

Paul go back to original bios you had at the start of this!! The one your at least familiar with the OC behaviour and work with the timings.

Will do, tbh there isn't much difference (option wise) between F3 and F8.

I found CR, was tucked in with the seconds.

Crazy it won't touch 2400mhz yet I can do this at 2133...

Lol this things a laugh a ******* minute.

Take bios screens, nice and easy yeah? Nope not for gigabyte, pressing f12 causes the system to hard lock

Hard locks on F3 and F8. So bios screens atm are out of the question.
