    Default G.SKill PI -

    Hello! First post here...

    I'm going to be installing, among other parts, some new RAM this weekend. My mobo is the GA-P35-DS3R matched with an E6750 CPU. I'll be installing the following G.Skills:

    Newegg.com - G.SKILL PI Black 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Desktop Memory

    here are the specs:

    <table class="specification" cellpadding="0" cellspacing="0"><tbody><tr><td class="name">Capacity</td> <td class="desc"><script type="text/javascript">document.write(neg_specification_newli ne('4GB (2 x 2GB)'));</script>4GB (2 x 2GB)</td> </tr> <tr> <td class="name">Speed</td> <td class="desc"><script type="text/javascript">document.write(neg_specification_newli ne('DDR2 800 (PC2 6400)'));</script>DDR2 800 (PC2 6400)</td> </tr> <tr> <td class="name">Cas Latency</td> <td class="desc"><script type="text/javascript">document.write(neg_specification_newli ne('4'));</script>4</td> </tr> <tr> <td class="name">Timing</td> <td class="desc"><script type="text/javascript">document.write(neg_specification_newli ne('4-4-4-12'));</script>4-4-4-12</td> </tr> <tr> <td class="name">Voltage</td> <td class="desc"><script type="text/javascript">document.write(neg_specification_newli ne('1.8V - 1.9V'));</script>1.8V - 1.9V</td></tr></tbody></table>

    should i expect to have to change anything in the BIOS or would you expect the mobo to recognize the timings and be good to go?

    thanks!

    If you have the board set-up and running already and plan to just swap memory in, you may need to adjust timings and volts b/c of existing ram, but more than likely it should be fine.
    I went from a 2x1gig set of GSkill 2BGHZs and it detected the timings on it's own. Of course my HZs were 4-4-4-12 stock.

    XP Sp3

    installed the ram and it booted up fine, however, according to everest, they're not at the right timings. here is the report.

    what do i need to do to get them running at 4-4-4-12? ..or am i misinterpreting that report?

    Use CPU-Z and check in bios it will show 4-4-4-12, everest might show incorrect report ram timings

    Everest is a nice program but I don't believe it is entirely accurate. I agree CPU-Z is the way to go for this parameter. Your question is a good one though. I can see where the confusion occurs. It looks to me from the line:

    Memory Timings 4-4-4-12 (CL-RCD-RP-RAS)

    That your mem is running just fine.

    This data:

    @ 400 MHz 5-5-5-15 (CL-RCD-RP-RAS) / 23-51-3-6-3-3 (RC-RFC-RRD-WR-WTR-RTP)
    @ 266 MHz 4-4-4-10 (CL-RCD-RP-RAS) / 16-34-2-4-2-2 (RC-RFC-RRD-WR-WTR-RTP)
    @ 200 MHz 3-3-3-8 (CL-RCD-RP-RAS) / 12-26-2-3-2-2 (RC-RFC-RRD-WR-WTR-RTP)

    Just confuses me. One day I may look into exactly what it means but currently I don't care.

    G skil black pi 6400

    If using the 4-4-4-12 special epp.it needs 1.8-1.95 v up to 430-433 mhz fsb
    433fsb-453fsb it needs 2.0v
    Above 450 mhz fsb you have to use 5-*-*-*-*
    500mhz fsb(1000mhz mem) works stable with 5-5-5-15 at 2.1-2.2v setting depends on your vdroop.(I need 2.22v set in bios,2,16v with v droop) to hold 1000mhz.
    I cant get it to boot above 1015 (507mhz)mhz even with 2.26 v set in bios and i dont want to go higher

    thanks for the reply kick, i don't necessarily follow it, but i'll try to figure it out.

    ...and Grippy, yeah, plugged them in, booted up and it seems that they're running just fine. i'm still not sure at what speed they're running or if i'm getting the most out of them.
