    Same problem with G.Skill's Pi 9600 4Gb kit...

    Run 2 x 2Gb MCH voltage cannot be raised on 2:40 strap until a certain level.... 2 x 1Gb or 4 x 1Gb and you can use the strap and mch voltage you want!

    Read this ram comptiable ram works with UP3P by review at Egg link at

    Customer Reviews Of mushkin 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory - Retail

    I am not saying you should buy it but get idea about reviews reports that brand works with UP3P right off the bat.
    I read, that they are running DDR1066 or more, but nothing about the MCH-Voltage?
    Can you show me the post?

    With my setup (see signature), MCH voltage settings are NOT a problem when using the 2.00(B) strap. I've gone as high as 1.32 volts, but my best results are with MCH set at 1.22 - 1.26 volts.

    I've successfully run & stress tested with the 2.40(B) strap:
    bus clock = 457
    memory @ 1097 (2.4x457)
    MCH =1.24
    tRD=8
    tRFC=62 (intentionally loose)

    The remainder of the bios settings closely follow LSDMEASAP's recommendations.

    I figured I would give this a bump since I also have the same problem with the 2.40b strap not booting above 434fsb.

    Can you give a little more information? Can't really help you without knowing your hardware and your other settings. Does a higher MCH Core voltage also cause instability for you?

    I have the same problem as Max, Jor3llBR, and others have, 2.40B will not boot higher then 433fsb with more then 1.20mch. Im wondering if anyone has found a real fix for this besides booting at low fsb or mch and then changing it later in ET6?

    Well that sounds odd how you say that? Sounds to me like you just should use less then 1.2MCH then. Some straps will need more or less voltages, depending on the ram speed, ram amount, tRD set, and all other settings.

    What is your issue here, that you need less volts to run 2.40B and 433+ FSB, thats not a issue that is a plus so I am confused on what the issue at hand is

    Also you need to keep in mind the B Strap will not always work with all memory when you go above 399 FSB, some work fine at any FSB using B, some do not for sure.

    What tRD are you trying to use, this may be a large part of whats holding you back?

    I just did a crucial review (See my signature) and could run 460 FSB using 2.40B without issues so it may just be all in your settings as well?

    FSB 434 and up with 1.22+mch will bootloop
    FSB 433 and lower with 1.34 (what I normally run) will boot windows fine
    FSB 434 and up with 1.20mch will post and load windows but crashes at welcome, not enough mch to be stable but any more wont even let it get this far

    I can boot up at 433fsb with 1.34mch then up the FSB in windows and be perfectly stable, but why wont it let me boot with that FSB preset in the bios with 1.34mch? I have a P5Q dlx also and this hardware has no problem with that strap at any FSB or NB voltage using essentially the same settings as this board. Performance level was set 9-11, no go. I have seen several people with similar setups but all different brand rams with the same problem.

    Why so much MCH Anyway? I mean you have not said why, and it may not be needed at all. What tRD are you trying to use, and what Vtt and MCH Ref do you have set?

    Let me see your full settings that are failing for you at 435+

    And as I said, some ram will just not run the 333 strap above 400. Do you have any other to test with, a different brand I mean?

    I have tried to get samples for compatibility testing and review but have been ignored by OCZ.... and Corsair passed me off from rep to rep and eventually ignored me by not replying after the last pass off. Bad PR I guess, or they do not wish to offer help to their customers in as many possible ways as they could?

    Other companies (Gigabyte, Crucial, Mushkin) have had no issues with supplying products for such reasons, very fast to reply and send out items, and continue to be supportive in a great way. I guess who your PR Reps are matters a lot these days when it comes to customer service and trying to offer support to customers from many angles.

    You will see no loss running the D strap at those speeds and I can tell you I have seen it actually test out better that way a few times

    This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours

    Default Re: P45 UD3P - Large RAM Problem

    I have different ram coming tomorrow, same brand OCZ but there the 2x2 9200 reapers. There the main reason I need the 2.40B strap to boot correctly to get there advertised 1150 speed. If they end up being able to do 1200mhz ill just skip the 2.40B and go with the 2.50A. Since I normally run 482fsb and my current ram will only run up to 1120 ive been having to use the 2.00D for now. I know there will not be much of a loss running the D strap (for me everest shows slight improvement with 2.00D at PL9 vs 2.00B at PL10) but the problem is I need to run 2.40 which there is none in D strap. I dont think the ram is the issue here since it has no problem booting this strap on my Asus board with whatever nb voltage and FSB using essentially the same settings as this board. I have not fully tested yet how low mch can go and still be stable in windows but I know 1.20 isnt close to enough. At 465x9 (essentially the highest I can go right know with my current ram on 2.40B), 2.40B, with 1.2mch (highest mch that allows me to boot higher then 433fsb) windows will boot but fails prime within seconds and crashes. If I move mch up to 1.22 or more it will bootloop and restart, this is using the amount of reference to keep it about the 67% area. Now if I boot up at 433x9, 2.40B with 1.30mch then up fsb in windows to 465 with ET6 it will be perfectly stable and pass prime blend with no problem. This is using the same settings each time only changing the FSB and amount of mch with appropriate reference to keep at about the 67%. So why would these settings that are perfectly stable in windows not be able boot up when preset in the bios? This seems like a bios issue to me.


    This will boot but crashes in seconds. If I try to up the mch to 1.22 or higher with appropriate reference it will not boot, bootloop.
