F2-6400CL5D 4 Sticks in GA-EP45-UD3P

[mayan50]

I have been having problems with spontaneous reboots of my system.

GA-EP45-UD3P (rev 1.1) mobo with Q9400
with
4x2GB G.SKILL Dual Channel F2-6400CL5D-4GBPQ (Total 8GB)

I ran Memtest86 v2.11 and get lots of errors on first pass begining at Test 3

I ran Memtest on each stick separately (in slot 1) and they check out fine.

Could someone PLEASE tell me if I need to modify any settings in BIOS, I'm using defaults as I don't want/need to overclock, just want stability.

On AUTO, the BIOS are defaulting to 5-5-5-15, 1.8v which matches GSKILL's suggested settings. HELP?

[Tradesman]

With the 8GB you may need to manually raise your tRFC (60+) RAM Timing setting (and possibly others).
Otherwise at stock settings 5-5-5-15, command rate 2T, and voltage at 1.9

[mayan50]

Actually, I have been trying to troubleshoot this via help from the Tweaktown Gigabyte forum. I have tried raising the tRFC a few times (need to start writing numbers down but pretty sure I've gone well over 60), also have definitely tried the ram voltage at 1.9v. I don't think I've tried the command rate at 2T (what does that do by the way?) In the past day, things have actually gotten worse, couldn't even post last night, so I'm back to 1 stick in currently with Optimized Defaults loaded.

Such a common motherboard this is, seems like someone would have an identical set up.

[Tradesman]

It's basically the time needed between set signal and issuing a command, 1T is considered tight (preferred) and 2T is a nit looser, most Intel chips work well with 2T

[genetix]

-You need 2T in every case.
-No you do not need to change tRFC to anything.
-Run voltage with 2.00v minimum (2.15v even wouldn't be too bad 8GB 4 sticks needs voltage so simply give them that).

I own same board same memory. Works flawless with CL4-5-4-14 on 800Mhz with this set, if not then quote this message and tell me what test fails and with what memory area on MemTest86+.

-Only latency I suggest changing is tRAS keep that between 14T(on CL4) or 17T(on CL5).

[GSKILL TECH]

Never use the default settings, they will have worse results. Set memory frequency, timings, and voltage. Increase NB Voltage to 1.4V. If you are still having instability issues, list the advanced timing values so we can see how the motherboard is taking the memory. Or to make it even easier to troubleshoot, please post screen shots of the BIOS and we will be able to locate the issue.

Also, make sure Performance Enhance is set to Standard otherwise sometimes it will throw the motherboard off.

Keep us posted on the results.

Thank you

And to repeat I'm using 4 sticks of the F2-6400CL5D (dark blue)

[Tradesman]

Sounds like a winner, now if you'd like you can OC the 9400, it's a decent OCer.

[mayan50]

No winner! Can't even boot with the settings that I posted.

I meant to say that I'm still having problems.

[Tradesman]

Sorry bout that, think I was checking another post, on your, from above, might try to the arrowed numbers:

Advanced Timing Control
tRRD......................................3.....: AUTO >4
tWTR......................................3....: AUTO >4
tWR........................................6....: AUTO >8
tRFC.......................................52...: 80 (have tried other lower values) >64
tRTP........................................3....: AUTO >4
Command Rate (CMD) ..............0...: 2

[mayan50]

Tried those advanced settings, and thousands of errors begining on Test #2.

What next?

[Tradesman]

This may be reduntant, but what OS are you running XP, Vista or WIN7 and assuming it's 64bit version?
Are all you drivers up to date...and... do you have any add-on USB devices or a TV tuner..RAID...SSD?

If you can pass that on, in the meantime...you could pull two sticks - leave the two in slots 2 and 4 and disconnect any add on devices. Boot, go into BIOS and set the BIOS to default settings (exception being boot from hard drive. If it boots and runs OK, then add teh other two sticks into 1-3 and try that. If it doesn't boot OK, try the same thing starting in 1-3 then adding to 2-4. Any BSODs along the way write the error message and pass it along.

These mobos have problems between 1-3 and 2-4 as the prime slots. You may also want to try the Beta BIOS F10e dated 7/27/2009 (it's been out a couple of months and I'm sure it addresses some of the RAM issues they have had.

[mayan50]

No RAID, or any other bug spray for that matter.

Running Vista Ultimate 64

Only USB device is/was a Microsoft cam.

F9 Bios running.

I've tested every stick and every slot separately and in pairs, all ok.
