Athlon XP-M DFI Nfinity help.

I have an Athlon XP-M 2500+ and a DFI Nfinity motherboard. I'm using 1 gig of Corsair value select ram and a GeForce 6800nu. When I run the processor at the stock 133 x 14 speed everything runs fine. If I up the bus speed to 166 and lower the multiplier to 13 it runs 95% stable (for lack of a better way to describe it). And if I run a 200 mhz bus it doesn't matter if I run a 9x multiplier or a 12x multiplier, it runs only somewhat stable. I can adjust my voltage anywhere between 1.65 and 1.85 volts, it doesn't seem to matter, the stability doesn't get any better. Also, at the 200mhz bus speed it seems my data starts to get corrupt, and I fail Prime95 in like 30 seconds. Temps recorded by the motherboard seem ok until I get to the 1.8 volt range where the CPU starts to get to upper 40's/low 50's. I'm using a Thermalright copper cooler and a 92x25mm fan with Artic Silver 5. I just reformatted and rebuilt the PC last night as Windows stopped loading with a ".dll needed for kernal were not loaded" error appeared while trying to use the 200mhz fsb. Right now I am running 133x14 until I can figure out a fix. Also, I have booted into Windows as high as 2.6ghz (200x13) but stability was horrible. My power supply is an Aspire unit, the 12volt rail is rated at 34 amps, if I recall correctly.

Please help! 🙂
 
Sounds like (this is an educated guess based on the info you gave) it is either your motherboard or the RAM.

Try running your FSB at 200Mhz x 9 mult but run the memory async and set it to ~133Mhz or even better yet if you can snag another stick of PC3200 RAM stick that in. Your RAM is PC3200 right? If those are two 512MB sticks you could also try running them one stick at a time. Basically try to rule out that it is not the RAM. Also get a copy of MemTest86+ and run that to test your memory.

Because your system is stable at 133x14 I doubt it is the CPU and your temps are reasonable so it sounds like your heatsink is seated properly... maybe your powersupply, although I doubt it. Also, although I love DFI I find there quality control sort of sucks. I am 2/2 on DOA boards from them. Maybe I just had bad luck... the replacements have been rock solid however.
 
I did have a stick of generic PC3500 memory, with that I had very similar problems, so I don't think memory is the issue. I gave that memory to a friend figuring that may be the problem, and got the Corsair memory. If I remember right, I may have had even worse problems with the generic PC3500. In his PC the generic PC3500 memory works like a charm.
 
hmm, this thread is interested because i have practically an identical setup.. DFI infinity ultra with 06/19 bios, 74gb raptor on SATA-RAID, BFG 6800nu OC unlocked pipes and vertex, corsair 2x512mb value select, and amd 2500-m @ 200x12, vcore=1.8, vchipset=1.8, vdimm=2.8..

try upping the voltage on your chipset and ram. and maybe try the same bios as me
 
Yeah... what AlucardX said.

I have a similar setup... just so you know, your temps aren't bad, at all.

I have my 2600+ running at 200x12.5 @ 1.725 V (not stable, yet - runs prime95 for 12 hrs. now I'm trying 1.75 V), and I get load temps of around 52-53C (with SLK-947U and a 2600 RPM panaflo.. don't remember which one).
 
also, i got this board from a buddy and he put active cooling on the northbridge, which for some reason i think the default shipping boards for the Infinity do NOT have. highly recommend you get a fan/hs on the northbridge, and take the NB heatsink and put it on the southbridge. he also has a few little heatsinks on some mosfets but that shouldn't be necassary.
 
I've been running my voltage on the chipset at 1.6 and the ram at 2.7. I'll try a little more voltage, and I'll look into an active cooling solution for the northbridge.
 
Also, I don't have a floppy drive and don't know what date my bios is. Is there a way to flash it without a floppy? Also, how can I tell my bios version, does it show it as the PC starts up, or is it somewhere in the bios menu? Thanks again for all the replies.
 
^^^^

What he said.

I am in a similar situation - I was just going to try and make a bootable CD in nero from the bootable floppy image provided to bios flashing, but I'm not really sure if that would work...

Not clear to me why you would need to up the chipset voltage when trying to run @ 200mhz FSB. The dang thing's rated for that.

I just up the chipset voltage when going much higher than 200mhz.

Set your multi to 9 or 10 (sometimes multi's under 10 don't work well). FSB to 200mhz and then run memtest overnight. Let's take ram out of the equation. You shouldn't need to use high a vcore to run the CPU stabely @ 2ghz. I run at 2.4ghz with 1.55vcore.

If it passes memtest overnight, test w P95. If that's OK, up the multi to 11 and do P95 again. Rinse and repeat.

What are your ram timings?

Do you have Motherboard Monitor 5 on there? I always use when when OCing. Select the "sys log" feature and elect to have it write the recordings to a text.doc. every second. Keep an eye on the PSU rails. Look for fluctuations. They'll mess up an OC pretty quick.

If you were going above FSB @ 200mhz, I'd say post your BIOS settings. But shouldn't be critical at this stage.

Here are my RAM timings:

T(RAS) -7
T(RCD-Read) - 2
T(RCD-Write) - 2
T(RP) - 2
CAS Latency - 2.5
T(RC) - 13
T(RFC) - 15
T(DOE) - Auto
T(RRD) - Auto
T(W2P) - Auto
T(W2R) - Auto
T(REXT) - Auto
T(R2P) - Auto
T(R2W) - Auto
SuperBypass - Enabled
SynModeMemoryBypass - Auto

Anything that should be changed here?

I'm going to try and run 200x10 and run memtest.
 
I set the CPU to 200mhz x 10 and changed my CPU voltage to 1.65. As soon as I tried to boot into Windows I got an error that Windows could not load because of a softare problem, and some required .DLL's were missing or corrupt. Odd. 🙁
 
So...uh...is this good? 🙂

Memtest Results after about 2-3 minutes.

I like how the errors are coming so fast that the number blurs on the screen. 🙂 Also, I notice that it says I'm only running 64-bit (single channel) and not dual channel. That shouldn't be, should it? Do I have to enable dual channel?

Also, it seems to no error when Im at 133mhz, but I only ran it for a few minutes.

And lastly, I used to have a stick of generic PC3500 (one 512MB stick) that I could not run faster then 166mhz in this motherboard. Between that memory and my current memory not being able to run at their rated speed, I still am thinking motherboard. But, anyone have any other ideas?

Thanks again for the replies. Atleast I'm getting somewhere now.

As it looks like your having problems passing memtest, see above for suggested changes to timings. Basically, I'm suggesting 2.5-3-3-11. Your BIOS offers more settings for ram ram than I am familiar with 😱

No point in proceeding until memtest can make it overnight w/o an error.

Fern

EDIT: per the screen in memtest, your ram timings are 2.5-3-2-7. So, change the "2' to a "3", and the "7" to an "11"

If that doesn't do it, change 'em to 3-3-3-11

You should have an auto type of setting. The most stable is usually called "optimal". That should give you 3-3-3-8 which s/b close enough. I suggest it because I don't what the heck some of those settings are, wanna make sure there are no conflicts. If it still fails, try one stick at a time

Corsair VS lately all defaults to 3-3-3-8 even at FSB @ 200 and should pass at whatever FSB you're running now.

For DC, put sticks in slot 1 & 3, or 2 & 3. If it's in DC you should see it on the POST screen at bootup

I'll make those changes tonight (at work now) and see what happens. Also, I was thinking about this on my drive in to work today, I only changed my FSB to 200 but kept my memory setting in the bios to "By Speed" when I ran memtest. So that meant my memory would be at 200mhz and my FSB would be at 200mhz. When the PC runs stable I set the FSB at 133mhz and leave the memory at "By Speed" so it would still be at 200mhz, then? I guess I'll check tonight.

Also, anyone have any idea why I'm running in single channel mode?

Thanks again.
 
the memory timings is definitely your problem. my PC with 2x512 corsair value select won't even POST at 2.5-2-2-11, set your ram to optimal configuration and let the bios handle the timings, you can tweak it later when you get it stable.

or set it manually in expert mode to 2.5-3-3-3-11, which is what i use. then set, under genie bios, your cpu fsb to 200mhz, and your memory to 100% or SPD so it runs at 200. you definitely should be able to do at least 10x200.. i can do 12x200 no problem with vcore at 1.8v

also, your bios information is at the bottom of your screen in the lower left, when your PC posts and its detecting ram and showing IDE devices (first screen). can't help you about flashing without a floppy, i believe the board has awdflash built in by hitting alt+f2 but i wouldn't use it.. in addition to the fact that i dont know how you would load a new bios without a floppy to pull it from.
 
Well, I found the dual channel slots. I had ASSumed that they were the two slots nex to each other, but it is infact the two outside slots (leave the middle one empty) to run dual channel.

Also, I still got some errors until I ran dual channel. Now I run memtest and it runs through until it is done, then the PC turns off. No errors though. So I guess for some reason I had to run this memory in dual channel for it to work correctly?

I'm going to try and figure out how to make it loop (I see that was mentioned above) and get it to run over night.

I am making this post at 200mhz x 10. 🙂 So, I'm atleast getting somewhere now.

Thanks again to everyone for all the help.
 
I was running fine at 200mhz x 11 @ 1.65 volts. I upped the multiplier to 12 and booted into Windows. The PC locked up when trying to run Super Pi, so I reset the PC and upped the voltage to 1.75. While in the bios the PC shut down by itself. Maybe it was shutting down by itself when I was running Memtest last night? I let it sit for a while and I was able to set it back to 200mhz x 11 @ 1.65 volts. Is something over heating perhaps? My memor is at 2.7 volts, chipset is set to auto, and the CPU is at 1.65 volts right now. Anyone have any thoughts?

Thanks again.
 
1. whats the make and model of your power supply
2. for me to run 12x200 i need at least 1.8v on vcore

i have a feeling you have a crummy powersupply.. i'm running a 350w enermax 365-p and it runs everything fine: 3 harddrives, 6800nu, etc.. its only 350w max but its a quality supply and i have never had issues with it.

oh, also.. make sure you plugged in the auxilary 12v 4pin power connector from your powersupply to the DFI board. the 12v plug is right above the AGP slot.

and check out dfi-street.com forums.. tons of info on there.
 
This is my power supply. It is a 500 watt unit, and I bought it because it seemed to get very good reviews. But, maybe that is the problem?

I'll check out the DFI forums as well. Thanks.
 
PS looks ok then.. but again make sure you plugin the 12v 4pin. and don't be afraid to crank up the vcore.. the amd mobiles can take quite a bit, just don't go over 2.0v and 1.8 to 1.85 should be more than enough for 12x200
