mr.fresh Posted February 5, 2005 Share Posted February 5, 2005 Ok, here's a good one for ya'. I purchased a pair of matched 512's XMS PC3200 a while back for my Asus P4P800 to run in dual channel. Great, no big deal, but then I decided I wanted another gig so I bought another pair of the exact same thing off the same very popular *cough newegg* website. Well I figured since it's all the same I could just fill all my slots however I wanted and it wouldn't affect my dual channel. I was WRONG. Turns out one of the sets is DOUBLE-sided and one set is SINGLE-sided. Don't know which, but that's not the point. So.....I can get it to run in dual channel, but I have to run 1 of each type mixed with another in each channel to get dual channel. In other words they are placed in this order.....double-single-double-single. I figured I'm S.O.T. for exchanging so I've dealt with it. But now HL2 keeps crashing on me and I have a feeling it has to do with this RAM. Btw, I haven't actually removed the heat spreaders to inspect, but CPU-Z tells me this is how it is. Also, according to CPU-Z one of my sets is designed for different latency.??? If someone could help me I would forever owe you my gratitude. Anyone want to trade a gig? Which one's should I keep? Single or Double? Ahh! Link to comment Share on other sites More sharing options...
mr.fresh Posted February 5, 2005 Author Share Posted February 5, 2005 sorry, but I really could use the help.......bump^ Link to comment Share on other sites More sharing options...
Wired Posted February 5, 2005 Share Posted February 5, 2005 What is the exact part # and revison # of each stick? How To Read the Memory Label Where in CPU-Z is it telling you which are dual sided and single sided? DO NOT TAKE THE HEAT SPREADER OFF. It will void the warranty.

mr.fresh Posted February 5, 2005 Author Share Posted February 5, 2005 Ok here goes. I've got lot's of info. Hopefully we can figure this out. The last two images show the double-bank and single-bank in Asus probe (not CPU-Z like I thought..sorry!). http://img207.exs.cx/img207/9752/dscf04515qt.th.jpg http://img207.exs.cx/img207/3728/mem18yd.th.jpg http://img207.exs.cx/img207/2596/mem23en.th.jpg http://img207.exs.cx/img207/4234/mem35pv.th.jpg http://img207.exs.cx/img207/1815/mem49zq.th.jpg http://img207.exs.cx/img207/1157/mem54zw.th.jpg http://img207.exs.cx/img207/3886/mem61fi.th.jpg http://img207.exs.cx/img207/3855/mem75fw.th.jpg Link to comment Share on other sites More sharing options...
Wired Posted February 6, 2005 Share Posted February 6, 2005 CMX512-3200C2 XMS3202 v1.2 0351022 CMX512-3200C2 XMS3202 v3.2 0430005-1 OK, so it's a TwinX1024-3200C2 v1.2 and a TwinX1024-3200C2 v3.2. Ok, Double-BANKED. If you run the "double-banked" sticks by themselves in the same slots, do they still come up as double-banked? If you take that pair out and replace them with the other pair, in the same slots, do they come up the same? Take the double-banked sticks out of those slots and put them in the other slots. Still come up as double-banked? Mainly trying to see WHY they come up like that. Just checked my Asus A8V, it shows my NON-ECC memory as ECC, so I'm not trusting that program at the moment, and yes, my memory is showing up as DB.

mr.fresh Posted February 6, 2005 Author Share Posted February 6, 2005 Ok, left the v1.2 pair in the slots they were in (the blue dual-channel slots) and removed the v3.2's. PC-Probe reported that they were Double-Bank. I then removed the 1.2's and put the v3.2's in the same slots and PC-Probe reported them as Single-Bank. It's funny because I would have figured the v1.2's to be the single-banks considering they are older. So v1.2 = Double-Bank and v3.2 = Single-Bank. Any ideas? Btw, thanks for your help in this matter. One other interesting tidbit. I just put all the sticks in again, but this time in a different order like this....(v3.2)(v1.2)(v3.2)(v1.2) and my pc would not even boot! Couldn't even get to BIOS, it just froze at splash. I pulled the old versions and am just running a Gig until I get this sorted out. Link to comment Share on other sites More sharing options...
Wired Posted February 6, 2005 Share Posted February 6, 2005 No problemo! Well, it's safe to say that it's the sticks themselves saying that, just dunno why. It may be programmed into the SPD, it may be a chip layout. It's rare to find 512s that are single sided, but I don't know if single sided = single bank. I'll have to poke Ram Guy about this one on Monday. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 7, 2005 Corsair Employee Share Posted February 7, 2005 First thing, with most MB's that are out now, all of the modules would need to exactly matched both in part# and revision. In addition, the Revision 3.2 modules are indeed single sided. As well as if you are trying to add 4 modules you would need to consider 48 Watts just for memory. And I would try and manually set the timings to Cass 3-3-3-8 @ DDR400 at 2.8 Volts and see if that helps. Link to comment Share on other sites More sharing options...
mr.fresh Posted February 7, 2005 Author Share Posted February 7, 2005 Ok, so I can get my system to run, but I have issues with random crashing that I feel could be my memory configuration. Shouldn't I be eligible for an RMA? I did order the same part # so how could I have known they were different revisions? If I do fill out an RMA form, which modules should I send back? Will I be able to get another set of version 3.2? Thanks. Btw, my psu is an Enermax 460 watt. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 7, 2005 Corsair Employee Share Posted February 7, 2005 Well do the modules run and pass http://www.memtest.org one up? If so then that is not a warranty issue. However, I have no problem replacing your modules, but you would need to get an RMA for all of them and send them all and request they all match. Other wise our system will try and replace with what you send in. Maybe a better way would be to send the new modules back or and order Twinx2048-3200C2. And just find another use for you old set. And 460 Watts may not be enough depending on the system configuration. Can you tell me the settings you had set for both CPU and memory? As well as a detailed system spec?

mr.fresh Posted February 7, 2005 Author Share Posted February 7, 2005 My CPU settings were set to stock (Socket 478, P4 3.4E, fsb=200 X 17) HT Enabled. Memory set to 400Mhz, 2.85v, 2-3-3-6. Memory acceleration=Auto, Turbo=Auto. CPU-Z reports memory acceleration as disabled. My complete system specs are as follows: Motherboard: Asus P4P800 (i865 chipset) Processor: Pentium 4 3.4E RAM: 4 X 512 Corsair XMS Hard Drives: (C:) WD 80 gig 7200 Special Ed.

All in an aluminum case. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 8, 2005 Corsair Employee Share Posted February 8, 2005 Let me put it this way, you have almost 350+ watts max continuious needed for that config, and that PSU is probably working really hard. And I would try and set the timings to Cass 3-3-3-8 with all four installed and see if the system is more stable. Link to comment Share on other sites More sharing options...
