M4N72-E w/ 9950be on pc 6400

[jhoffa_84]

Hi guys, first post. Love the site have always used it .
Im having troubles with this new build. Its my first quad core build, so i might be missing some things. Purchased a Asus M4N72-E 750a and 9950be, running Patriot pc 6400 2x2gig. stock 5-5-5-12 2t. My pc keeps shutting down w/ no blue screen, under load, in windows you cant really tell.. At 800mhz fsb/dram ratio is 1:2. I pushed the speed back as far as the motherboard would allow to 667mhz. and brought my timings down to 4-3-3-10-14 2t, and that gave me a 3:5 ratio. Still same trouble. i have modified my cpu voltage to 1.45v and my NB to 1.4v and my ram to 2.0v, which is max according to partiot. Any advice? or any more info needed?

my specs

Asus M4N72-E 750a
AMD 9950 Black
4 gig Patriot dual channel pc 6400.
630w psu w 43A +12v
gtx260 216 55nm
seagate barracuda 7200.11 32mb 500
vista 32

Your PSU is not big enough for your GFX card. You will need a PSU that has at least 40 amp on one rail alone. for the 260. I had the same problem but my fan on the psu stopped working. Either The psu is shutting down out of thermal reasons or it isn't giving enough current under load. Sorry. Corsair 750 or 1000 watt.

My PSU has ran this card for 3 months. My problems started happening this week with my new motherboard and processor. I may just have to purchase 1066 ram. Although the pc6400 runs very good. aside from the shutting down under load, after about 15 min.
also, a power calculator that i used came up with 500w power requirement for my hardware.



a quick edit. While browsing through bios, I noticed in the NB settings that EPP was disabled. My ram supports EPP @1.9v so i set it. So far no problems. could this have affected it? or could i still be looking at a problem? should i still try to tighten my timings down?

All I am saying is that if it is shutting down w/o blue screen, it is the psu. I bought a 650 and my problems went away. I had a 550 odin. You have to remember that your 9950 is a 140 watt cpu. Depending on the board u are using this may be an issue. 9950s are hogs. Ph II consumes much less. I still think its the psu. Sorry once again.

my 9950 is 125w

Just fyi, if you choose to get it, the Ph II X4 940 Black Edition works in that MoBo.

There is some issue on how the ram works when running an OS Vista 32 vs 64. With the 64 you can run 1066, but with the 32 bit you can't and you won't get more than 3.0 Gig of ram to work, if I'm remembering that correctly.

I'm running it with 64 bit which works great, but I learned the hard way about all the things I have, programs, that won't work in 64 bit. Like my HP T45 printer.

leave the side panel open to see if that help. maybe case's airflow isn't good enough and something is overheating

 

[jhoffa_84]

yeah. My temps are normal, i have dual monitors so i can constantly watch my temps. GPU max 75C, northbridge has gotten up to 52C and my cpu has gotten up to 52C. My temps should be within operating levels. Also have 2 120mm fans 2 80mm fans. and my box is set for pretty good airflow.

i have 4 gigs installed but it gives me 3.25g all good tho.

last night after enabling EPP, i havnt crashed once... I read somewhere that EPP slows your mem down???

I think you should be using the 1066 memory for the Phenom. Go to BB, Micro Center or a CompUSA and buy a stick of 1066 and test it out..

The reason you get 3.25 is because you're on 32 bit.

Also your video card alone needs a minimum of a 500 watt PS....

i was thinking it may be power, since i didnt get a bluescreen as if it were a hardware error. also. i was contemplating about taking my ram up to 2.1 or 2.2v it says max is 2.0v. I have a friend with a 750w psu i might try to swap him out just to see if that may be an issue.

 

[jhoffa_84]

It was power.. my 630 was not strong enough. I have a 700 with a single 12v rail. seems to deliver a more consistent stream of power.
I do have a question about my cpu voltage. I currently have my multi @15x 200fsb = 3.0g. I have my voltage in bios set at 1.4 but it always reads lower on my voltage monitoring software. What should the proper ballpark voltage settings for this chip @ 3000?
