GA-EX58-UD3R rev1.0 / 6Gb GEIL Triple Channel Kit 1333MHz 9-9-9-24

[ga-fan 09]

Hi, We recently put together a brand new system

Specs

Code: [Select]

GIGABYTE GA-EX58-UD3R
i7 2.66GHz 920 D0 Stepping
6Gb GEIL Triple Channel Kit 1333MHz 9-9-9-24
Sapphire Radeon HD 4890 1GB Graphics
2x Samsung Spinpoint F1 HD10 Hard drives
1x Samsung EcoGreen F2 Hard Drive
700W CoolerMaster Silent Pro Modular PSU
Samsung & Pioneer DVDR Drives
AeroCool Series S9 Case
2x 12CM ALASKA Silent Fans (Side of Case)
1x 12CM ALASKA Silent Fans (Back of Case)
System seems rock solid now with 1 stick of GEIL 3 chan ram after many
teething  problems, although this doesn't help us as we need as much
memory available as possible.
We came to the conclusion that the board doesn't like
more  than  one  stick  of  ram  from  this GEIL triple channel kit,as
mentioned in the post to CCL, we noticed a board revision on Gigabytes
official  site  to  1.6  and  still  wonder  if  this is why the board
revision was made?

We initially bought 4x sticks of stock 2GB Ram, but CCL recommended we
get a GEIL Triple Channel Kit 1333MHz 9-9-9-24 and go with 6Gb.

At  this  point,  can  you  suggest some settings for the BIOS for this
Triple Channel Kit...or if getting a
Corsair Triple Channel Kit: TR3X6G1600C9 would be a better suggestion.

This is the post on the CCL website after getting no help whatsoever,
in fact they told us we'd invalidated the warranty by updating the
BIOS to F7a from tweaktown.

We  collected  the  PC on Fri (19/06/09) still with F7a BIOS, with the
report  we  posted on the above thread. We immediately flashed it back
to  F6  BIOS  with  no  problems...  we can't understand why CCL had a
problems trying this, they even suggested we get a new BIOS chip?

When we put one stick from this kit in the motherboard, the VCore voltage
doesn't   increase  past  1.18750V,  if we put all 3 sticks in the
voltage fluctuates on Auto between 1.18750V and 1.19375V.

We've seen posts on forums  with  people  increasing the VCore voltage
to get a stable system, this looks like what you have to do when putting more than
one stick of ram in, which is all we want to do, we don't want to overclock in any way.

We've tried other suggestions from posts like disabling
CPU Multi-Threading, CPU  Enhanced  Halt  and C3/C6/C7 State Support, but
Vista64 SP2 with the 6GB just reboots at the initial boot screen, or sometimes gets
to the desktop then BSOD's...

Please help

Thanks GA-Fan

I also had some problems using Geil on Gigabyte mobo but the older model. As i don't have experience with these voltages so I suggest you to change your RAM into other vendor. Maybe this list will be helpful somehow:

tweaktown is really nice place for looking at beta bioses, I have tried it few times and never killed any gigabyte mobo.
Even if you kill the mobo this way and CCL rejects your warranty claim you can always do direct RMA to Gigabyte UK as far as i know.
