ram extension

[pascal_bidouille]

Mother board Gigabyte P55-UD5
RAM 2x F3-16000CL9-2GBRH
Processor : Intel Core i7 860

Hello,

I want to extend RAM but I cannot find anymore F3-16000CL9-2GBRH in any shop.
Can I extend using : F3-16000CL9D-4GBRM ?
Timings are slightly dirrefrent :
9-9-9-27 for F3-16000CL9-2GBRH
and
9-10-9-28 for F3-16000CL9D-4GBRM

What timing will MB affect to memory when I put both ?

[pascal_bidouille]

or would it be just better to change it all to go to F3-17000CL9D-8GBXM for example ?

You could try, but anytime you mix sticks from different packages, even of the same model it can be problematic - especially with high freq DRAM, sounds like you are looking to go to 8GB so with your mobo I'd suggest a single set of 4x2GB or (preferably) a 2x4GB set. If you OC at all (imagine you do since running 2000 sticks now) would suggest a 2x4GB 2133 set like the SnipersF3-17000CL9D-8GBSR or Ripjaws X F3-17000CL9D-8GBXM, there's also others available

ram extension F3-17000CL9D-8GBXM on P55-UD5 : problem

Hello,

Following your advice I got some F3-17000CL9D-8GBXM.
Tried them on my system (replacing my old one).
Result : blue screen and reboot each time I try to start windows.
I checked bios settings :
I can see 2 XMP profiles :
Profile 1 : 2004 MHz
Profile 2 : 2136 MHz
Tried both without any luck.

Even windows safe mode starts but fails quickly when I try to run any tool.

Any Idea ?

Thanks

I forgot I have bios version is F11b (can be usefull)

[Tradesman]

Looks like they updated the beta BIOS to F11C, might try that w/ XMP

[pascal_bidouille]

Hi,
I just tried it loaded F11C and for sure with XMP.
Same result.

I also did a memory test with memtest86 booted on USB.
Test runs without error.

I have win 7 and dual boot win8 consumer preview.
When I start on win7 : I get failure more or less when desktop start to appear.
Wehn I start on win8 : I can get to desktop, start a few application (like two browser before it fail.
Seems like the problem appears when memory fills a bit over 1Gb.
Bad luck I don't have any more linux to try...

[pascal_bidouille]

Also, just for test I tired with only one RAM module (thus only 4Gb)
Same result

P55-UD5 and F3-17000CL9D-8GBXM

One more tests : boot on ubuntu (on USB) :
No any better, PC get stuck before unbuntu finish to load.
(for sure I tried my usb with ubuntu with original memory : woks fine...

Conclusion : I do not have a clue :
As it doeas not work with Win7, WIn8 and Ubuntu I would tend to exclude any driver problem.
As memtest does not find any problem I would think it proves memory works fine on my motherboard.

Any idea ?

[Tradesman]

Might try at 1600 just as a test....then we can go up from there...Also what type of OC do you have on the CPU, since an OC will be required to run at spec

[pascal_bidouille]

HI,

I tried with memory multiplier x10 so speed 1670. result NOK
No OC at the moment, came back to default (almost).

Any idea ?

[Tradesman]

What does XMP set the sticks to? Should be 9-11-10-28 2T 1.65. At 1600 can try 8-8-8-24 or possibly 7-8-7-24 prob down to 1.6 or 1.55

[pascal_bidouille]

yes with XMP I have 9-11-10-28 2T at 1.65

At 1600 I think I had 8-8-8-24 at 1.5

[pascal_bidouille]

1600 ok

Hi,

I got it to work at 1600 :

SPD Ext. EPP

Not quite sure what I changed from previous tests as in both case timing are defaults.
(so I was wrong in saying 8-8-8 in prev post, that's in fact why I checked tonight)

HAve to make it go faster now ...
