currently have my 700@980, will PC150 help me achieve stability?

[rapidbaboy]

again, i currently have my 700@980.

i also have PC100 RAM, running with 4/3 multiplier to get 105.

i usually get page faults. temperature is fine, mobo is 31C, cpu is 38C even with 1.9v

is memory my bottleneck? will upgrading to PC150 RAM and run it at 140FSB flat render my system stable?

thank you.

it all depends on the quality of the RAM. for instance, Kingmax sells PC150, but is only rated to do so @ cas 2-3-2 or something like that. likewise, Mushkin's PC150 is also only rated to do so @ cas 2-3-2. now Mushkin's PC133 rev2 is rated cas 2-2-2 @ 133 mHz and can be OCed to 148 mHz stable...at least those are the success stories i've heard. some people claim they could OC to 150 mHz and higher while still running cas 2-2-2 with the rev2 stuff. Mushkin's PC133 rev3 is rated cas 2-2-2 @ 150 mhZ, which raises the question, "why would you get PC150 cas 2-3-2 @ 150 mHz when you can get PC133 cas 2-2-2 @ 150 mHz?" i guess it just boils down to the price of RAM. i would say that a move from PC100 to PC133 would more than likely help with your stability problems. but to be sure, are there any other errors you get besides page faults (and i'm assuming you mean page faults while browsing the internet)?

PS - did you post a question about CPU temperature in the PC Abusers Forum? someone posted there also claiming to have OCed their P3 700 to 980 mHz, and that was the first time i have ever heard of someone OCing a 700 to that specific speed.

thank your for the quick reply.

no, its my first time to post here at the anandtech forum.

i've been running my p3-700e@980 with 1.9v, using an alpha p3125s and air cooling. i'm the few lucky ones i guess. well, yes, page faults. invalid page faults mostly. and i know page faulting is a memory issue. i also tried the sandra burn in program, and i got the page fault during the 6th memory benchmark.

well, i'm thinking of getting the mushkin PC150 rev3, which is rated at cas2 (2-2-2). whats bothering me is, since i'm using the 4/3 multiplier, meaning my PC100 isn't really stressed at 105, since i was able to run the exact RAM with my 733 at 150fsb (825mhz), with the 4/3 multiplier. so, the PC100 RAM ran at 112.5mhz cas2. anyway point is, could it really be a RAM bottleneck? will upgrading to PC150 RAM help me reach stability? save me from page faults?

in figures. i currently have PC100@105 with my 700@980. will getting PC150@140, bring me stability? the "invalid page faults" occur not only in internet explorer, but also after a few hours of seti@home, "invalid page fault", seti crashes. or let's say while running prime95 with torture test, i run IE, then boom, "invalid page fault", IE crashes. to my knowledge, page faulting is a RAM problem. if my system would hang or lock-up, then i'd assume my chip can't handle 980. but since its just usually "invalid page faults", its gotta be RAM... right?

thank you again.

i would also say that this is a RAM issue. if page faults are the only things causing your programs to crash, then i am very hesitant to say its your CPU. most likely its the RAM. since you were more specific about your page faults and how they happen, i am not so sure that a different kind of RAM is the solution. the problem might lie in the sticks of RAM you are currently using. maybe one of them is partially fried or something. i had a similar problem in which my old system would constantly freeze up. the mouse wouldnt even move across the screen...it would just get stuck in one spot...everything would freeze. not even a ctrl-alt-del would restart it. i had to hit the reset button to restart the system. after days of trouble shooting, Dell sent me a new mobo (same make and model as it is part of my Dell warrantee). everything worked fine, and i havent had any freeze ups like that since i got my new mobo. so it could be a mobo issue. i dont know what kind of mobo you have, and even if i did, i dont know much about mobo makers and their warrantees and policies. but you might want to call them and ask for tech support. i would imagine that if your mobo is under some sort of warrantee (and dont mention that you OC or anything b/c that will void the warrantee) their tech support can help you with your problem and maybe even send you a new board if they cant fix it. its worth a try b4 you go out and buy some new RAM. but if you plan on upgrading your RAM anyways, get the PC133 rev2 or rev3.

by the way, i am also one of those lucky OCers...i have a P3 700E @ 1036 default 1.7v Vcore and i cool it with a golden orb
