Core voltage stability on 865PE Neo2 PFS

I've just installed one of the new P-series NEO-2 MOBO's. Nice piece of work, although it seems there is still some work left to be done. Definite problems (although not serious) in Core center (althoug other posts indicate this may be indiginous to core center itself..)
More serious though is a reading of the processor core voltage.
I'm using a Celery 2.6, OC'd to 3.25G, FSB 125. Had to raise core voltage to 1.6V to get there, lower voltage led to crashes as low as FSB 104...
Recently, I looked at a scan of the core voltage (provided by Speedfan):
The problem lies in the fact that during disk access and/or high processor load, the core voltage drops as much as 90 mV, bringing it back to its default setting (spikes in graph, longer drop was writing DVD, CPU benchmark has similar result).
If it does this at 1.5V, I can understand the crashes.
I get the impression this board could do MUCH better with more stable voltage regulation.
Anyone seeing similar behaviour in other Neo2-boards? Am I missing a setting?(core-cell may be intervening) It's hard to imagine the PSU can't hack it.. 12V level is rock solid.
System: MSI 865PE Neo2 PFS, Celeron 2.6G @ 3.25G (125 FSB)
             1x corsair 3200 512MB @ 333
             POV 5600 VIVO
             WD800BB 80GB
PSU:      HEC 350 VD-PT (3.3V@28A, 5V@33A, 12V@15A)

I'm not worrying. Just a bit surprised we all make a bug fuzz about overclocking, increasing core voltage by 25 mV at a time, and suddenly ignoring it all and "accepting" 70 mV drops if we need processing power...  
If the voltage regulator would be more robust, it would be able to maintain the Vcore to (much?) higher power ratings.
This board drops by roughly 70 mV, constituting 3 notches on the voltage setting tab.
I went up to 1.6V, and what I actually get is 1.52.....  
To have 1.6 available under all conditions, I'd need to set to 1.7 (yes, I've tried), which is over the top for "normal" overclocking (not to mention considerably higher temperatures).
Anyway, I'd like to know what other boards are doing regarding Vcore stability. Anyone out there with additional data?
Maybe a new target for modifications?  (if it's worth it...)

  • [865PE/G Neo2 Series] DDR Memory with 865PE Neo2-PFS Platinum

    SYSTEM SPEC: 400w PSU, Pentium 4 3.2ghz 800mhz FSB (HT), Matrox Parhelia 128 8x AGP card, MSI Neo2 PFS Platinum motherboard.
    Hi there. Im looking for some serious help with my computer. I have a MSI 865PE Neo2-PFS Platinum mobo and have been using 512mb DDR RAM with it- the ram is PC2700 (333mhz), non-ECC, ubuffered, non-parity, 184 pin. Now, I have just purchased a new DIMM. This one is
    1gb PC3200 (400mhz), non-ECC, Unbuffered, non-parity, HIGH DENSITY- DUAL IN LINE, 128 x 64, 184 pin
    It doesnt work and my system refuses to boot up. I checked out the specs of the 865PE Neo2-PFS Platinum, and it says in the table that you can only use 400mhz DDR RAM with an 800mhz FSB processor (which I have). It says it supports 400mhz RAM, "DUAL CHANNEL", non-ECC, unbuffered memory, but no mention of "HIGH DENSITY" or "DUAL IN LINE". Is there a difference between "DUAL CHANNEL" and "DUAL IN-LINE". Also, does anyone know what the difference is between 128 x 4 and 128 x 64, they are both 1gb? SOMEONE PLEASE HELP!!! I have seen some RAM from the same dealer which is not "HIGH DENSITY" and has the 128 x 4 configuration, and is still a 1gb module. Is that safe to buy? What RAM do I need (in detail) for my motherboard. Thanks!

    Always useful with a complete systemspec.including PSU and biosversion, so please make one.
    Can´t see anything wrong with the basic RAM specification - it also matches the MoBo basic specifications:
    - Supports four unbuffered DIMM of 2.5V DDR SDRAM.
    - Supports up to 4GB memory size without ECC.
    - Supports Dual channel DDR266/333/400/433/466/500/533 MHz and up.
    Have you tried removing the old RAM and booting only with the new 1GB stick alone ?
    Using mixed RAM, sometimes works in "Single mode" (see mobo manual), but is not recommended.
    Running Dual-channel ( 2x512 or 1024x2 ) is preferable and gives best performance, but then you need two identical sticks.
    You may also need to increase RAM voltage some in bios (example 2.7v) to achieve best stability.
    If you have some RAM compability issues with 1GB sticks - 2x512 RAM stick would be safer and give better performance, unless your aiming for more then 2GB in total.
    You can also read about the RAM testreport here;
    http://www.msi.com.tw/html/products/mainboard/testreport_pdf/6728v2.0/memory.pdf
    About "Dual In line Memory Module" - I think it´s the long version for older DIMM description.
    Just like "Double Data Rate" is the long version for DDR RAM.
    DDR means Double Data Rate RAM (in opposition to the SDRAM or Single Data Rate). DDR RAM bends the transfer rate for clock cycle. It can go quicker because it executes 2 instructions for cycle of clock of the RAM instead of an only instruction like it is the case of the SDR.

  • My "MSI 865PE Neo2-PFS Platinum" Is not working

    I have an MSI 865PE Neo2-PFS Platinum and it has stopped working properly, I'm fairly sure that the problem is coming from the motherboard however I would like another person opinion.
    Basically everytime i try to play a game it works for about 5 seconds then comes up with a bluse screen telling me to check Windows has needed to shut down because there has been an error and that it could be caused by drivers or that I need to disable BIOS caching and shadowing
    So far I have tried disableing BIOS caching and shadowing. Changing the RAM around and using different modules. I have formatted the Hard Drive. Tried using a different graphics card. Reinstalled the BIOS. Uninstalled all the drivers and tried different ones.
    None of this has made any difference.

    Since you already have reformated/made a fresh OS install, here´s some things you can try…….
    - Set dram voltage to 2.7v in bios
    - Use Driver Cleaner when uninstalling VGA drivers
    http://www.majorgeeks.com/download3214.html

  • 865PE Neo2-PFS Platinum and PCI-e

    Hello,
    I am using a 865PE Neo2-PFS Platinum atm, with an AGP slot GFX card. (9800 pro).
    I want to upgrade to PCI-e and want a few pointers for a decent socket 478 board that is PCI-e ready. I don't want to have to change my CPU.
    many thanx.

    Indeed...
    I was just pointing out that even the fastest agp card is lots slower then a midrage pci-e card.
    I still think any upgrade to the agp system is a waste of money. CPU limitation  ... 478 P4's rly aren't fast enough to feed modern gpu's
    In case he still wants a agp card
    the 7800GS is the obvious choise, and you might want to check out albatron's 7600GS agp card.
    EDIT: this socket 478 asrock board has a pcie slot http://www.asrock.com/product/P4Dual-915GL.htm (don't forget to read the VGA card compatibility list on that page)

  • [865PE Neo2-PFS ] - No Boot Media

    ive got everything installed and when I put in my XP Cd, I get a black screen with a blinking _ and nothing happens. Is there something im not doing or someing ive done wrong??
    Thanks for your help

    You can flash from anything, but flashing from a floppy is dangerous. You can boot from a USB stick and flash from it. You can boot from a Win98/ME cd and flash from a ram drive. There is a link in my signature for booting from a USB stick.
    This will show how to flash from a cd:
    Go to this thread. Download the zip file and burn the iso image on it to a cd. If you don't have software for burning ISO images there is a link in my signature to a free one.
    Download the bios and flash program from the motherboard page and put in a directory on your hard drive.
    Put the CD in the tray, reboot, and press the F11 key to select the cd drive to boot from. The cd drive becomes a:, c: is a ramdrive, and your c: drive shows up as d:, etc.
    Change to c: (the ramdrive)
    Copy the flash program and bios image from d: (your 'real' c: drive)
    Flash away.

  • 865PE Neo2-FIS2R and Geil memory problem

    With 512MB (2x256) of Corsair XMS 3700, the system is perfectly stable (runs 24/7 crunching for UD, also have done Prime95 torture test).
    With 1-GB (2x512) of Geil PC4000 Ultra Platinum, the system is very unstable.  It usually won't even boot fully into Windows without a BSOD (which vary) or if it does get into Windows it crashed soon thereafter.
    If I put the Corsair memory back in (like I have them right now, to be able to use the system to post this message), the system is back to 100% stable, so it seems to be entirely a memory-related problem.
    MSI 865PE Neo2-FIS2R (MS-6728)
    Intel P4 2.4C 800FSB (HT enabled) @ 3.19-GHz

    AGP volts 1.50
    SPD Disabled

    Have run MemTest standard test on the Geil modules individually and as a pair, and have tried different slots.  Testing thus far shows no errors when each module is installed separately, but when used in a pair there are sometimes errors shown.
    Have tried the modules in slots 1,3 and slots 2,4 with no difference.
    Have tried setting DDR voltage from 2.70 up to 2.85v for the Geil (approved up to 2.9v) with no apparent change in stability.
    Have tried changing Spread Spectrum setting between enabled and disabled.  Disabled seems to be better, but problem remains.
    Have tried using SPD disabled with settings listed above, and SPD enabled (which sets timings at 2.5-4-4-8,8).
    Edit: I'd asked for advice, but then realized that the very limited timeframe in which I could return the Geil would expire if I waited beyond business hours today.  So I've RMA'd the Geil and have ordered a 1-GB Corsair TwinX XMS 3700 pack instead.

    I've had similar problems to you but with Corsair TwinX LL's and if you read back a month in this forum you will see others have also with various memories on the 865 FISR.
    The fix I found was Kingston memory but others have had problems with Kingston.    There was a thread running a week or two ago attempting to document successful memory mobo combinations.
    Bottom line, stick with what works on your mobo until MSI fix the incompatability/instability issues.

    Thanks guys for the replies.  Yes, you are right, I was hoping specifically for the 865PE-NEO2-LS board, and see no responses.  At this point, hopefully my 3.4 Northwood should be here today or tomorrow.  On this board, I just could not get past 3.1 Ghz with my 2.8, and it seems as soon as I started creeping towards the FSB of 230, things really went wacky/unstable.  No matter if I raised the voltages, loosened memory timings, etc.   But having said that, CONGRATS to you guys for getting your 2.8s juiced up - I wish I had better luck!
    Obviously, my next question would be is how well does the 3.4 Ghz Northwood O/C - isn't the ceiling about 4Ghz?

  • 865PE Neo2-V problems

    I'm hoping this is the right area to ask for help...  Ever since I got this MB it's been nothing but trouble. I bought it, took it home, hooked it up, no power.  So I went back to the computer shop I got it from and asked them what's wrong with it.  After taking my system in for them to make sure it was setup right, they informed me that I had to send it back for RMA work.  so now, about 2-3 months later I finally got a new board back, and have random reboots.  I've tried everything I could think of to figure out why it's randomly rebooting and am stumped.  One surefire way to make it reboot is opening the front of my case, that does it everytime, so I tried a different MB to see if the same problem happen.  It doesn't...  Was there a re-call or something on these MB's?  I hate to do another RMA and be without a computer for a few more months, since I work out of my home, and my computer is a main part of my work...  I can't afford to send this MB in again.  I've got the latest BIOS update, my RAM is set to 2.5,3,3,8 (per manufacturer).  I have a 2 gig P4, that works fine in my other board.  Even bought a new SATA HD for a fresh install of windows XP and still, the random rebotos happen.  I'm not trying to OC or anything along those lines, since the chip I have shows almost no increases from OC's, so it's not from OC'ing it..  I'm running a 480 watt power supply, and that should be more then enough juice for the board...  Sorry to rant and rave, but been working on this for about 3 weeks and about to pull out all my hair, since everytime I think it's going to be ok and I start to actually accomplish some work, it reboots, before I have a chance to save anything...
    I guess I'm asking if anyone else has had these problems with this MB, or do I just have that kind of luck?  I've been looking over the boards here for the last week or so and tried pretty much everything I've found, under a search for random reboots, to no avail.  Here's a list of what I can think of off the top of my head that I've tried...  <deep calming breath>  Changed the BIOS through every version since the initial BIOS the driver disk has on it, re-seated the RAM in different places in the DIMM's, Memtest388 or whatever it is with 0 errors on a 10 hour test (the longest it's run without a reboot since day 1), pulled the graphics card and re-seated it, put more fans in, taken them out, took the power supply in to have it tested (it's fine), replaced the RAM with new shiny RAM that's tested fine, tried a different case, reset the CMOS, tried a different chip, tried numerous power supplies, checked the voltage at the surge protector, replaced all old components (CD drives, floppy drives ect...) traced each individual wire checking for breaks insulation problems, software tests out the wazoo all saying it's fine, new heat sinks, new thermal gel, put the computer on top of a cold vent (thinking of might be to hot) and so on...  I guess I should list my setup since every component in the case has tested out fine at the shop and I can't afford to replace anything else...

    I have almsot the same set-up as you have.
    I didnt have these problems though.
    One thing that comes to mind is a grounding error.
    Have you checked the space between the motherboard and the side of the case its mounted to?
    I read that you tried a diffrent case, but it could be some issue with one of the grounding points where you put the screws in perhaps.
    I know that the Spread Spectrum setting in BIOS can cause some disturbances, but it shouldnt really be enough to make it reboot though.
    But check that one anyway, ON and OFF.
    A bit info on Spread Spctrum:
    "Spread Spectrum
    When the motherboard’s clock generator pulses, the extreme values (spikes) of the
    pulses creates EMI (Electromagnetic Interference). The Spread Spectrum function
    reduces the EMI generated by modulating the pulses so that the spikes of the pulses
    are reduced to flatter curves. If you do not have any EMI problem, leave the setting at
    [Disabled] for optimal system stability and performance. But if you are plagued by EMI,
    activate the Spread Spectrum for EMI reduction. Remember to disable Spread
    Spectrum if you are overclocking because even a slight jitter can introduce a temporary
    boost in clock speed which may just cause your overclocked processor to lock
    up. Options: [Disabled], [Enabled]."
    I assume you tried to run the Load BIOS Setup Defaults.
    Also make sure that all the jumpers on the motherboard are set right, there might be some of the set wrong by accident, check with your manual to be sure.
    You can try this to, take out your motherboard and place it at a non-conductive material.like wood or glass and attach all the components u need to do a boot-up, and only those, and see whats happening.
    If it runs ok like this, then it might be some sort of short-circuit somwhere.
    I think i read about an ASUS board that had some components near the CPU that somehow got in touch with, either the heatblock, orsome connection point of the fan-mounting and it caused some serious problem for people.
    I took quite some troubleshooting to find that out for them.
    All i can think off right now, at the top of my head, but try this, if you havent done it already.

  • HELP with overclocking 865pe neo2!

    i have a P4 2.8GHz and an MSI 865PE NEO2-S mobo
    anyway
    ive tried sevrel times to overclock my cpu through the bios and reached 215MHz only... after that the system gets stuck even though the cpu temp isnt really high...
    after a while i discoverd the overclocking option in CORE CENTER and tried to over clock through there and everything went fine but when i reached like 230MHz the system got REALLY slow
    and i noticed that i dont know  about the voltages that need to b changed and everything
    if any1 can help plz help
    :P
    thanks a lot!

    I have looked at the example they have here on the site and it shows the corecenter with a red circle with OC in it for overclocked.  No where can I see where this is on my core center.
    I ended up in the bios and selected "Private" and "Ultra Turbo" and some other settings can't remember what but it got the chip up to 3500mhz.  How do I take this further or what's the purpose of the "General" setting as opposed to the "private" setting?
    How do I boost the FSB speed?
    What does PSB stand for?
    Just open up those stupid side wings and you can adjust your speeds there.  Like Nykon said, it's better to go in the bios and do it.  Corecenter is good for checking CPU temps and fan speeds.  
    The Private setting falls under Dynamic Overclocking or D.O.T. for short.  It's a process that's controlled through the Corecell chip that detects when the CPU is under load and adjusts your FSB accordingly.  I'm not sure if it controls voltages, but I don't think that it does.  The deferent settings in D.O.T. just means you are allowing for more overclocking with D.O.T.  So Private would be the slowest (5% performance boost) and general would be the fastest (maybe 20-30% boost).  However, when OC'ing manualy it's best to disable this function.  
    Performance mode just tightens up your ram timings for better performance, which you can manually do under Advanced Chipset Features.
    FSB can be adjusted in your Freguency/Voltage window in bios, it is the "Adjust CPU Clock Speed" heading.  
    PSB stands for Pet Shop Boys, but FSB stands for Front Side Bus.

  • Cant oc 865pe neo2 pls more than 3.19

    i have
    msi 865pe neo2 pls
    p4 2.8 HT
    ati redoen 9800pro
    cant get my cpu to overclock more than 3.19 when i do and save the settings it show them in the bios as a 3.2 but when i boot into windows with core center and system manager it reads the cpu as 1.6 it declocks it if thats possible
    i think i need to change my multiplier is this true if so how do i do and what do i do
    thanx for the help if u can

    Hi - Please write your complete pc config. next time, because it is easier for people to help it they know your pc components - You can do it by login - profile - signatur
    Intel cpu multiplier is not possible to change- it´s locked ( to 14 in your case )
    but try changes in bios as a start...........................
    The 2,8 cpu is not the best OC chip ( except the M0 stepping ) so you may only reach to about 230FSB ( 3,22 Ghz).
    Bios settings, based on Kevin Keenan´s advice.
    MAT/DOT Set to OFF
    DRAM FREQUENCY = 333 ( means 5:4 ) - if you have ddr400 / 3200 mem, otherwise if you have ddr500 you can go 1:1 with auto.
    SPREAD SPECTRUM = OFF
    ADJUST CPU CLOCK = 230
    AGP/PCI FREQUENCY = 66/33 or whatever is closest to that
    CPU VCORE ADJ = YES/ON
    CPU VCORE = 1.525 (If unstable add voltage (1.6v safe)
    DDR VOLTAGE = 2.65 (If unstable add voltage (2.8v safe)
    AGP VOLTAGE = 1.5 (If unstable add voltage (1.7 safe) ATI sometimes like 1.6
    Memory = SPD or Your manufacturer's memory timings
    AGP Aperture = 64MB
    Save and exit bios.
    There are more too it, but I think this is the fastest and easiest way start with.

  • 865PE Neo2 -FIS2R Problems

    I purchased a brand new MSI 865PE Neo2-FISR along with a P4 2.4C(OEM), a Thermaltake Spark 5c cooler and a Corsair XMS Twinpack(TWINX512-3200C2PT) of DDR400 memory.
    The install went fine, the system booted and ran very well right out of the box.  I installed the Live Update program from MSI and it updated itself.  I then used that utility to generate a BIOS flash/recovery disk to update the bios from 1.10 to 1.30.  The update worked fine and I rebooted the machine into Windows XP with no problems.
    I then decided to do some tweaking in the new 1.3 BIOS.  After several unsuccessful memory/Dynamic Overclocking settings the system refused to boot.  I tried the Clear CMOS jumper to reset the defaults but it still would not boot.  I checked the D-Bracket, 3 red 1 green(lower right) which indicates that the video card is not initializing.  I attempted reseating the video card (a PNY Geforce4 TI4200) with no luck, I then replaced that card with a GeForce4 MX440 SE with no luck.  I tried four other video cards, 2 AGP and 2 PCI, with no success.
    At this point I pulled the board out of the system and let it sit with the battery out of the board hoping that the BIOS would reset to default values.  I reinstalled the board with all the hardware and again the same D-Bracket error with no video generated.  I tried different arrangements of memory using the new Corsairs and various other DDR333 & DDR266 again no luck.
    What is going on with this thing?  How could an errant timing change completely lock out the VGA card?  And why can I not clear the settings to allow the card to initialize?
    This thing is getting RMA'd soon if I can't find an answer.
    Anyone have any ideas or similiar troubles? X(

    \"The board therefore achieves the best performance in the whole test field.\"
    http://www6.tomshardware.com/motherboard/20030707/i875p-46.html
    with MAT and DOT enabled, without any apparent negative reports of stability.
    Is it that he used a Beta Bios: V1.3B3 (06/12/2003)
    Or was his MSI board a \'pre-press release\' mobo similar to the ASUS board and the production versions we are buying are missing certain components?
    http://www6.tomshardware.com/motherboard/20030603/865_PAT-06.html
    Or did he have \'hand picked\' memory from Corsair \"2 x 256 MB, Corsair PC3200 TwinX\" and didn\'t report it?
    There are a lot of reviews lately that have it as one of the fastest MB's around at the moment, here are a handful I found:

  • 865PE NEO2 FIS2R memory problem

    I have this 865PE NEO2 FIS2R with a 3ghz northwood (512K cache, 800 fsb).
    initially I bought a 1GB Geil PC3500 DDR dual channel kit. installed those into slot 1 and 3, installed windows...during install I would get blue screens. recently I bought a new PC-3700 DDR dual channel kit (industry standard generic stuff). I bought those cause the place I got it from claimed it works on the i875 NEO FIS2R. I figured if it works on the 875P, it should work on the 865PE. with the new memory I get blue screens a tad more often.
    I tried both geil sticks again this time as single channel in slots 1 and 2 (Ch. A). I still got blue screens. I did the same with the new PC-3700 RAM, blue screens with that too.
    I took those sticks out, and tried 1 Geil PC-3500 stick in slot 1, no blue screens.
    Whats the deal here? shouldn't dual channel memory work as dual channel in a dual channel board? WHy can't I use 2 sticks of the same RAM in this board!
    is it just incompatiable with geil dual channel? If so what about the PC-3700 RAM I tried as dual. I am thinking about trying a set of OCZ dual channel RAM, but I feel I already got $400 worth of RAM I can't use, I don't really want to waste another $200 if this is just a crappy board.
    I'm thinking of just getting the new Asus with the SiS 655TX chipset, supposed to be faster anyway. 2 sticks of RAM would most likely work in that board.
    I really don't want to spend anymore money on this though...I spent enough.
    the specs:
    P4 3ghz northwood
    865PE NEO2 FIS2R (with updated 2.3 bios)
    Chieftech 650 watt Power supply 36A, 36A, & 32A
    BFG geforce FX 5900 Ultra 256MB (also tried an old geforce 2 mx 32MB)
    memory tried: 1GB geil PC-3500 dual channel kit & 1GB generic dual channel kit
    3com Network interface card
    WD 120GB SE hard drive
    Plextor 8X DVD-RW drive
    Lite on 16X DVDROM drive

    This problem is not yet solved....
    I tried increasing the ram voltage to 2.8v, it ran fine for about 3 days...then boom..restart
    I am seeing other people are having the same problem with these 865/875 boards.
    after raising the ram voltage didn't work I tried unplugging all of my extra hard drives 1 by 1 with the memory set to 2.7v.
    I am at the point where I have only my boot drive connected with the two DVD drives.
    But I am still thinking its my power supply...that power supply caculator page says I need a 519 watt PS?? I have a true550 which is only 530 watt max.
    If I do need to add 20% to the power calculated, I would need a 622 watt PS???
    I am running speedfan now....how low is the voltages ok to drop to?
    the +12 dropped to 11.19, max is 11.80
    the rest of the voltages are staying more or less constant .
    Oh yea, on occasion the nb fan stops, I get a warning in corecenter saying 0 RPMs.
    Also I can't set the fans to high speed, 6000RPM for the nb, and 5000RPM for the CPU.
    If I set corecenter to user, and move the slide up to 8, the max is only 3375RPM for the CPU and 3750RPM for the NB fan.
    Also every once in awhile the power LED on my case will go out while the system is running.
    But thats been doing that for awhile now!
    I'm thinking I will connect up my other hard drives again and run this speed fan program again.
    update:
    I reconnected my drives, ran speed fan, noticed it stops responding after 10 min...I get an error saying smbus cannot be scanned...or something like that.
    Also I've got errors when downloading saying I have no ports available. it sounds like the bus is shutting down??
    This is not the only MSI 865PE NEO2 FIS2R I have ran into problems with
    it looks like I will be getting a new board next week....either an Asus or Abit.

  • Memory Problems - Advice on quality memory for 865PE Neo2

    I have 2 x 512 MB DDR400 in Dual Channel configuration in my 865PE Neo2 mobo. It's a noname brand (the only mention on it are the letters "VM"). A friend recently warned me about the problems that my arise with cheap memory, so I ran memtest-86 and Windows Memory Diagnostic (http://oca.microsoft.com/en/windiag.asp). WMD gave no errors, but memtest86 gave 2 errors. I then tested the sticks individually and standard tests gave no errors. I then ran the extended tests and it gave errors on the extra tests. However the errors were not always the same. Furthermore, sometimes a pass gave 2 errors, sometimes it gave 3. Since the memory is still under warranty I have two options:
    - Exchange for another set of noname memory sticks
    - Pay the extra cash for quality memory
    I'm inclined to take the second option, so my question is:
    - What brand and model of memory do you advise? I don't overclock and I probably never will. Reliability and stability are all that matters to me. Thanks in advance.

    Thanks for all the input. After running memtest for almost 24 hours with various tests, here's my findings:
    I didn't change a thing in my BIOS. Exactly the same settings that gave errors (everything in default mode and dinamic overclocking off). I started with memtest's default set-up:
    RSVD MEM: 112K
    MEMMAP: e820-std
    TEST: standard
    I ran the test for a total of 14 passes. No errors were found.
    I then, ran the extended test set-up for 10 passes. One 2 bit error was reported on the 5th pass and on the 5th pass only, in test #10.
    In the light of this, I decided to run test #10 isolatedly, to see if the error showed up again. In a total of 10 passes no errors were found.
    I re-run the tests once again, this time with the "ALL" test options chosen. 8 passes no errors.
    I then decided to change the "memory sizing" feature to "ALL BIOS" to test those remaining 112K that were no tested in the default set-up. The program jammed at test #3 after having reported 122 000 errors!   memtest's manual says this is not a stable test configuration on some mobos. I guess that is an understatement!  
    So, I decided to change "memory sizing" to "probe" mode which is supposed to be more thourough that the others and more stable than "all bios". After 11 passes, no errors were reported.
    What can I conclude from all this testing? Probably, that 1 or 2 sporadic errors have little or no meaning. Also, that memtest should be run more than once in order to have enough data for a reliable conclusion.
    As things stand, I believe I'll just make one more test: play some fast n' furious 3D game for a few hours If everything runs stable there is no reason to change memory. Anyhow, the seller wouldn't change it without finding some errors on it and chances are he wouldn't.
    I would like to hear the opinions and thoughts of others on this experience. Thanks.
