[GSKILL TECH]

For those who have problem withs G.Skill F3-17600CL7D-4GBPIS with Gigabyte P55 UD6 / P55A UD6 / P55A UD5, please download the BIOS below and update.

They are beta bios from Gigabyte and fix some memory compatibility issues with DDR3 2200 CL7.

gigabyte p55ud5 w/i7 860 +4gb PIS/2200 CL7 +W7

i too have been having some difficulty with this new gigabyte/gskill configuration. so far i haven't been able to get to 7-10-10-28 even after upgrading to the newer F6 bios. difficulties include: occasional bsods, more often there is difficulty booting into W7 and subsequent startup repair somtimes works and sometimes doesn't, these at stock clocks and voltages, i.e. no overclock. also overclocking has become somewhat problematic. prior to updating bios and upgrading to faster ram my ripjaw 1333 were able to overclock up to 3.8 prime stable. with the new PIS i'm lucky to get to 3.6. this morning i booted with the W7 disk and used the startup repair feature which seems to have had some positive impact on the system but i haven't been able to do any testing of it as yet. furthermore i did see the p55 "a" ud5 bios listed on the product page but i'm a little bit afraid of what might happen if i use this bios and the p55aud5 turns out to be wrong for my system since i don't have an p55"a" mobo.
will the system fail with the "a" bios or will it still work with my mobo ? and is there any indication of when gigabyte will bring forth their newest bios revision for this ram ?

thanx

Links fixed, sorry about the inconvenience.

Crap, it's even faster memory with lower timings than mine!
Maybe the will fix my issue?
I was trying to contact GA, but they just don't listen.

[GSKILL TECH]

What is your issue? Just make sure you have the latest BIOS, it should be best.

Thank you

This one of course, aka '4Gb issue', it doesn't matter what i set and how, how overclock etc, i have tryed everything.
But it works 2133mHz 8Gb QPI/Vtt lowered to 1.335V super-stable, never crashed.
Just as with 1800mHz 12Gb with higher ratio of NB + QPI/Vtt 1.280V - same amazyingly stable.

But i totally can't get 2133mHz 12Gb work together
I'm sure it can, since all listed is stable, and much more compareable to each other, but limited through bios...
Default bios was FB, i have tryed FC for a long time, then FD8 beta and FD9 beta (it claims to be compatible with much more hardware, but seem not with my memory)

Please, ask them to test compatibility...
Support of GA just spit in my face, without answering even.

[GSKILL TECH]

It can be very difficult for 12GB full slots. What is the highest QPI/VTT you tried?

Thank you

Let's say i don't afraid of such kind of dificulties)

I think it was 1.48V, but notice that most time i doesn't overclock my CPU at all, bclk is 133mHz.

[failure13]

So, what about it?

[GSKILL TECH]

Did you try working your way up to see what it really needs? DDR3-1900, 2000, 2100, 2133, ....

That way you know exactly what QPI/VTT should be, otherwise it may be too much or too little.

If you can, post up some BIOS pictures. I can check to see if anything is incorrect.

Thank you

Well...Just tested.

My test is based on everything about CPU and memory set on AUTO, but manually set base timings 8 9 8 24 2T and of course memory voltage set according profile to 1.65V (at my mobo gotta go to 1.68V to achinve this).

So by changing bclk i can achive a really accurate steps.

Ok, everything lower than 2000mHz works very good and stable, even with QPI/VTT set on auto.
2002mHz is last memory freqency that i could achinve and it sees 12Gb of memory, QPI/VTT auto setting to just 1.2V
Next i add just 1mHz to bclk, so memory set to 2016mHz - but it start to see 8Gb, and i have tryed to raise QPI/VTT step by step from 1.175V till 1.6V - nothing changes, still sees 8Gb.

If i'll add another 1mHz higher to bclk - it starts to see already 4Gb, raising QPI/VTT from 1.175V till 1.6V still do nothing.

This is fair enough test, and since it works very good and stable on 2002mHz wihout overvolts, i would highly like to achive 2133mHz, coz it performs much much more better on my system, than 2000mHz. Just don't see more..
And strange thing is that actually BIOS sees all memory, but it shows the enabled columns with only 4 or 2 sticks.

Please, try to contact Gigabyte support so they could update current beta bios compatability for my memory, i'm sure it's much more easy to you, they just don't answer me at all

That's how it looks

[GSKILL TECH]

Try 8-10-8-24, or 9-9-9-24, it may be too difficult for the three kits to work together at those frequency and timings. You are having more luck than most people, it is extremely difficult for three high performance kits to work together.

Thank you

Yes, and no...If it would be 4mHz quad channel, i would mind...but

Anyway, timings doesn't affect nothing here...

Not timings, not voltages nothing, but correct me if i wrong, now motherboard doesn't even try to boot it up actually (according to my screenshot)

I mean, in previous days with core2duo system, i have tested out 8Gb 2000mHz CL9 memory when it was close to it's death, to go further...
Bios and motherboard allowed me to but up even 3000mHz without having problem to detect it.. (funny right? )
And i'm sure it could go any further.

But this motherboard bios is surely jsut limit amount of memory, which actually detected.

I'm asking you hardly to talk with Gigabyte about this memory compatibility (limitations), coz i'm pretty much sure that it actually can run (maybe even without bsod or having heat trouble), we got a real chanse to fix it now (since they are in beta-bios phase), and this will make a lot of people happyer!

P.S. I wouldn't ask if it haven't boot 2002mHz CL8 12Gb, which is amayzing result surely, but i'm sure it actually can add 131mHz more, and run wihout any trouble,
