    Default EP35-DS3L Timings 6GB OCZ Platinum/Titanium

    Hi all, I am new to these forums but really need your help!

    • OCZ part number: OCZ2P800R21G / OCZ2T800C42G
      Module size and kit size: 2x1GB / 2x2GB
      CPU model and rated speed: Intel Q6600 2.4Ghz Stock
      Motherboard and revision: Gigabyte EP35-DS3L rev. 1.0
      Motherboard Bios rev: F6
      Video card: EVGA 8800GTS 640 OC
      Power supply: Antec NeoPower HE 500w
      Operating System: Windows 7 Ultimate RC x64
      CPU and System Cooling: Arctic Cooling Freezer Pro 7 and 4 case fans
      CPU and System temps:
      Purchased at/on: eBuyer 18 months ago / eBuyer this week
      Country: UK
      Memory voltage: 2.0 / 2.1


    I have had the 2x1GB Platinum sticks for a while now, and they have worked fine without any BIOS tweaking, but since I added another 2x2GB Titanium, I had been getting non-stop BSODs...

    I found the gigabyte sticky by lsd, and adjusted my timings to fit within his suggested brackets and selected +0.2v.
    These are my new timings:

    • Performance Enhance________________ Standard

      CAS Latency Time________________ 4
      Dram RAS# to CAS# Delay_________ 4
      Dram RAS# Precharge Delay________4
      Precharge Delay (tRAS)___________ 15

      ACT to ACT Delay (tRRD)________ 4
      Rank Write to READ Delay (tWTR)_______ 9
      Write to Precharge Delay (tWR)________ 5
      Refresh to ACT Delay (tRFC)___________ 54
      Read to Precharge Delay (tRTP)_________ 5
      Static tRead Value (tRD)______________ 7
      Static tRead Phase Adjust________ 0 (Auto)


    I haven't got a BSOD for about 6 hours since I changed those timings, so it's already got much better, but I was wondering if I could improve on this at all? Also, memset reports my ram as being pc2 6400-400mhz. What's going on there? Thanks for your help.

    400MHz is the memory clock frequency, being DDR(Double Data Rate) tat makes it DDR-800.
    According to OCZ's Titanium page They actually need 2.2v for those timings, what are the spec on the sticker?
    The Platinum has 2.2v EVP so maybe a compromise of 2.15v would help stability.

    Ya you may need to use 2.1-2.15/2.2 with 6GB. You may also need to raise your MCH Voltage as well.

    You can try these ranges if you want to tweak and test for performance and stability
    ACT to ACT Delay (tRRD)________ 3-4
    Rank Write to READ Delay (tWTR)_______ 3-6
    Write to Precharge Delay (tWR)________ 4-8
    Refresh to ACT Delay (tRFC)___________ 54 << This may be too low for 6GB, but test as is it may be fine (52-64)
    Read to Precharge Delay (tRTP)_________ 3-5
    Static tRead Value (tRD)______________ 6-8
    Static tRead Phase Adjust________ 0 (Auto)

    Ok, I used all the minimum timings you recommended and it all seems to work fine. I tested with orthos and memtest, and there were no errors. Thanks alot!
