Official GIGABYTE X38-DQ6/X38T-DQ6 Info/BIOS Thread

Got my new G.Skill 8000 PQ 4Gb and I would like to share timings and settings with you guys (with anyone who has this babies at least).

I'm running an E6750 @ 450x8 = 3600Mhz with vcore 1.35v (Everest says 1.34v, CPU-Z flutuates between 1.328 and 1.344)
RAM with 2.40 divider @ 1080Mhz with 1.98v

Everest timings dump:

Memory Timings:

CAS Latency (CL) 5T
RAS To CAS Delay (tRCD) 5T
RAS Precharge (tRP) 5T
RAS Active Time (tRAS) 15T
Row Refresh Cycle Time (tRFC) 54T
Command Rate (CR) 2T
RAS To RAS Delay (tRRD) 5T
Write Recovery Time (tWR) 17T
Read To Read Delay (tRTR) Same Rank: 4T, Different Rank: 6T
Read To Write Delay (tRTW) 8T
Write To Read Delay (tWTR) Same Rank: 13T, Different Rank: 5T
Write To Write Delay (tWTW) Same Rank: 4T, Different Rank: 6T
Read To Precharge Delay (tRTP) 7T
Write To Precharge Delay (tWTP) 17T
Refresh Period (tREF) 4213T
DRAM Read ODT 3T
DRAM Write ODT 6T
MCH Read ODT 8T
Performance Level 7
Read Delay Phase Adjust Neutral
DIMM1 Clock Fine Delay 7T
DIMM2 Clock Fine Delay 7T
DIMM3 Clock Fine Delay 8T
DIMM4 Clock Fine Delay 7T

I got a blue screen just half an hour ago while browsing some photos... Everest stress test won't crash within 5min. Maybe is the memory too tight and bluescreening my system?

Thanks in advance for your feedback.

First of all, i seriously doubt you can run the E6750 at 1.35v at 3,6ghz. I bet you'd have to up it to atleast 1.45v. I have the same cpu and i need 1.55v to be 100% stable on this board.

Also, memory is very touchy about running past 1066 on this system when using more than 1 module,- especially when using more than 2. I'd try 5-7-7-24 and up DDR voltage to 2.25

Get OCCT. If you can go past 2 hours in it without crashing you're most likely stable.

1.45v?! man, isn't that too high? Before changing memory I was running it at 3200Mhz with 1.28v and it was stable with gaming and everything... I never thought this CPU would need that many voltage with OC... :/

my sticks are the blue G.Skills (stock 1000Mhz 5-5-5-15). You don't think they can run 1080 with the stock timings? maybe just upping the tRAS to 18 will do it?

I will try OCCT. Thanks!

EDIT: and I'm running with two 2Gb modules.

e6750 is 1.35 at default 2,66ghz. Ive run it for a long time on 1.6v at 3.8 no problemo. As long as your cores are below 75C you should be fine. (these are bios settings, 1.6v would usually be 1.55v in OS under load cause of the bad droop).

With memory i guess its just trial and error. All hardware is different,- its all a big lottery. Just set up some decent setup and see how it fares in OCCT. If you crash within 30 minutes you need to either slack off settings or increase voltage and try again.

Thanks. I will try 1.45 in BIOS. Since I'm with stock cooling I'll keep an eye on the core temps just in case...
