Corsair XMS3200 v. 1.1 OC

Now I have been reading a lot of pages about the chips on Corsair modules.

It seems that Corsair handpicked a lot of BH-5 chips and used them extensively on the LL modules.
But I haven't seen anything concerning the chips on the non-ll module.

I have a strong feeling that it is BH-5 chips.
I know I could just take of the heatspreader and look for myself.

They are doing 200 Mhz at default voltage.

If indeed it is BH-5 chips, what would be a realistic OC speed?

    well i think it depends. i don't have a matched pair, and admittedly i haven't tried them seperately, but best i can do is 220 at relaxed timings. so, decide for yoself. i would think a matched pair could do better anyways - especially as it looks like people on abit boards are getting somewhere in the 220-230 range

    Yup, 230 seems to be about the upper limit without voltage mods. In my P4 board, with Corsair PC3500 which is BH5, 1:1 fsb:RAM, 230 is absolutely the limit @ 2.85v and (due more to the board/partly lack of voltage, I think) lousy timings. 231 will post but not last long. Also, reading Anandtech's reviews, even Mushkin LevelII black BH5 is topping out right around 230.

    However, BH5's are running 250+ for some, if you can get them 3.1v or more.

    TwinMos BH-5 chipped modules maxed out at 234fsb on standard voltages for me.

    I got 2x256 Corsair XMS3500 v1.1 (XMS3502v1.1) which are BH5 based (visually confirmed). But neither stick overclocks well in my NF7-S 2.0 rig (tried up to 3.4Vddr). 230-235 with relaxed timings max.

    I'm now running 2x256MB TwinMOS CH5, and these will take 242 11-2-2-2.0 (yes typical "BH5 timings") DC CPU Int enabled, Prime, memtest86, goldmemory, 3D and F@H stable 24/7 at exactly 3.23Vddr (more or less Vddr will make them less stable for me, 3.3V rail at 3.6).

    Some NF7's seems to prefer CH5 I guess :scratch:

    That sounds odd.

    Well I guess I have to take a look under the heatspreader.
    Is the heatspreader easy to remove, and reattach?

    It's BH5 :)

    No need to look. You should be able to see what you got with a flashlight if you know the visual cues to look for (markings partially visible even with the heatspreaders on, the thick thermal tape doesn't cover the entire chips). The circular "W" winbond logo should be easy to spot. On CH5 chips the logo is located far to the left, upper corner and more towards the center on BH5:

    Thanks
    I will inspect them later.
    I might as well do it while the case is open.

    LL 1.1 is BH5, LL 1.2 is CH5.

    All in all, it means that you should send me your sticks MJO ;D

    Edit// So your sticks are not LL? In that case, it's probably BH6 or even Samsung even.

    Bah I had the two modules out of the board.
    I looked and I looked, but I couldn't see anything due to the heatspreader.
    It covers pretty much everything.

    They are actually doing quite nice.
    I am at FSB 220 Timings 2-2-2-11.
    Vdimm 2.8.

    How much voltage should I give the processor?
    I have been testing my memory all day long.
    At speeds around 220 Mhz at all possible chipset/vdimm voltages, I have even relaxed the timings.
    Timings: 11-3-3-2.0
    Now I tried lowering the multiplier, I am running 1150 Mhz right now.
    It is sailing through Prime95.
    I guess my processor needs more power.
    I need a Barton, my memory has potential, my processor I dunno.
    Is the voltage normal for an OC'ed 1800 Dut3c?
    Think I need to up the Vcore to 1.85-1.9.
    It can take it though, it is nice and cool in there after I changed my heatsink.

    EDIT: Testing at 231 Mhz and no errors in Prime95.
    Now I need to get the processor up there as well.

    EDIT EDIT: Testing at 225 Mhz, timings 11-2-2-2.0.
    That is pretty good.
    I need to run a Prim95 torture test.
    But I installed windows at that speed and I haven't had any problems.
