Ga-ud3p-ep45 + f2-8500cl5d-4gbpi-b

[mongoose00318]

Hello,

I have a Gigabyte GA-UD3P-EP45 Rev 1.6 paired with a Q9450 and 8 GBs of RAM.

My ram is 2 pair of F2-8500CL5D-4GBPI-B. I actually had 1 pair of F2-8500CL5D-4GBPK before this but I had to return it because no matter what settings I used (I THOROUGHLY searched this forum and many others). So now I have this.

Again, I have thoroughly searched around for existing threads on getting 2 pair of this type of G.Skill memory working right with this board but I haven't found anywhere near as much information as I found with the 4GBPK.

Anyways, no I'm out of rope and I need your help G.Skill and G.Skill community please.

Here are my settings at the moment.

>>> CPU Settings
CPU Host Clock Control - Enabled
CPU Host Frequency - 333

>>> DRAM Performance Control
Performance Enhance - Standard
Extreme Memory Profile - Disabled
MCH Frequency Latch - Auto
System Memory Mulitplier - 3.20B (1066Mhz)
DRAM Timing Selectable - Manual

>>> Standard Timing Control
CAS Latency - 5
tRCD - 5
tRP - 5
tRAS - 15

>>> Advanced Timing Control (submenu)
tRRD - 4
tWTR - 4
tWR - 8
tRFC - 80
tRTP - 4
Command Rate - 0 (I tried 2 and it became really unstable...meaning more than it is now)

>>> CPU
Load Line Calibration - Disabled
CPU Vcore - 1.36250V
CPU Termination - Auto
CPU PLL - Auto
CPU Reference - Auto

>>> MCH/ICH
MCH Core - 1.400V
MCH Reference - Auto
MCH/DRAM Reference - Auto
ICH I/O - Auto
ICH Core - Auto

>>> DRAM
DRAM Voltage - 2.040V (this seems to be the most stable..any lower it freezes, any higher it BSOD)
DRAM Termination - Auto
Channel A Reference - Auto
Channel B Reference - Auto


I need your help! Thanks so much in advance. Go G.Skill!

Sincerely,

Mongoose

My cousin and I have been tweaking the bios settings to no avail. But, we are still working at it. Can we get some help here?


Thanks everyone!!!

Might try CR at 1T, tWTR 5, tRTP 5, tRFC 90 (and with the other timings might also try CR at 2T)

We've been messing around with it since my last post. We managed to get it pretty stable but still not completely stable. Let me show you my latest settings to see what you think.

>>> CPU Settings
CPU Host Clock Control - Enabled
CPU Host Frequency - 333
PCI Express Frequency - Auto
C.I.A.2 - Disabled

>>> DRAM Performance Control
Performance Enhance - Standard
Extreme Memory Profile - Disabled
MCH Frequency Latch - 333Mhz
System Memory Mulitplier - 3.20B (1066Mhz)
DRAM Timing Selectable - Manual

>>> Standard Timing Control
CAS Latency - 5
tRCD - 5
tRP - 5
tRAS - 15

>>> Advanced Timing Control (submenu)
tRRD - 4
tWTR - 4
tWR - 8
tRFC - 80
tRTP - 4
Command Rate - 2

>>> Channel A Timing Settings
Static tRead Value - 8
The rest - Auto

>>> Channel A Driving Settings
Driving Strength Profile - 1066MHz
The rest - Auto

>>> Channel B Timing Settings
Static tRead Value - 8
The rest - Auto

>>> Channel B Driving Settings
Driving Strength Profile - 1066MHz
The rest - Auto

>>> CPU
Load Line Calibration - Disabled
CPU Vcore - 1.36250V
CPU Termination - Auto
CPU PLL - Auto
CPU Reference - Auto

>>> MCH/ICH
MCH Core - 1.400V
MCH Reference - 0.76V
MCH/DRAM Reference - 0.96V
ICH I/O - 1.5V
ICH Core - 1.1V

>>> DRAM
DRAM Voltage - 2.1V
DRAM Termination - Auto
Channel A Reference - Auto
Channel B Reference - Auto

These are the MOST stable settings so far. But again, they are still not stable yet. Tradesman, do you see anything in the settings above that I need to change? The MCH/DRAM Reference has had quite an effect so far.

Tradesman, I am trying the settings you suggested now, in combination with the settings I just posted above.

Mongoose

[mongoose00318]

Tried the settings you suggested Tradesman. Also tried moving the MCH/DRAM Reference - .98V. It ran pretty stable for about an hour and then it froze up.

Here's a link to a screenshot that I took of MemSet 4.1 that shows my SPD values. I hope this helps some.

In case this bit of info helps I was using the FD bios version and now I am using the FFb.

tRFC is at 80, prob need at least 88-90 and maybe upwards of 100 for two sets. COuld also try higher DRAM voltage...however, may have two sets that just don't want to play together

[mongoose00318]

Ya we tried it at 80 and 90 and it didn't get us anywhere else. I will try 100 and let you know. I just hope I don't have to RMA this stuff too. This is the 2nd time I will have done that in 1 month.

[mongoose00318]

Does a G.Skill tech want to add their 2 cents??

[Tradesman]

Will drop him a line to take a look

[mongoose00318]

Still nothing. I tried the higher tRFC at higher settings like you suggested (100, 110 and even 115) and still nothing. WTF??!!!

[Tradesman]

Just got in a bit ago, can drop GSkill Tech another line, though it will be Monday before he's back, will see if anybody I know has any ideas

[GSKILL TECH]

Make sure each kit is installed in the same color slots. Since this is not a 8GB kit, it can be a memory matching problem.

tWTR 5
tRTP 5

DRAM Termination should be half DRAM Voltage

Let me know how that works.

Thank you
