Quick Prime95 question

im using prime 95 to test my new overclock, and i was going to stress my ram. to do that i started a custom test and set the fft as 2048k-4096k. letting prime run for a few hours will check my RAMs stability, right?? or did i mess that up? Thanks

if i run the small ffts i get a blue screen and i need to restart it. so i thought that i would just test the ram so i can concentrate on the cpu later.

also my q6600 (9x333) runs at about 60c-65c while running the small ffts. i have a zalman 9700, is this normal?

you want the multicore prime95 version to test all 4 cores aswell

seems a little hot for a decent copper cooler

bsod's mean you have pushed something too far, or without sufficent vcore (or too much etc)

What RAM are you running?

also here is a list of my system specs
Q6600 (9x333) 3.0ghz Vid is 1.2625v
zalman 9700(temps idle around 40c)
Msi P6N diamond
Mushkin 4gigs (4x1gigs) @800mhz

cpuv is + 0.075v****any less and the comp blue screens constantly, any more and it restarts constantly, this is the only voltage that works.***
NB-SB 800mhz
FSB voltage is at +%12
North bridge volts is at default
South bridge volts is at default(1.5v)
RAM votltage is at 2.0v
All RAM timings are set to auto.

ok, il do that and post my results as soon as run some tests. and ive had no problems with my ram for over a year so i think its good but il still test it

i also posted a different topic here after i had some different problems

http://www.tomshardware.com/forum/ [...] e#t1765025

and should i increase the ram's mhz or leave it linked to the cpu, my mobo dosent allow me to set a cpu/ram ratio, but it does allow me to link them

blarg MSI problem number one, and i think that N stands for Nvidia, which chipset is that? something that can actually pull off 1333mhz FSB without increasing the chipset vcore?

oh, and set your ram manually to 1:1 (667mhz per channel), and raise your cpu vcore till it floats just below 1.4v and see how that goes (shouldnt need it but this is MSI garbage, and its prolly vdroop'ing below 1.2v anyhow, and 1.45 is even considered safe etc)

The standard 'blend' prime95 option will do that just fine, memtest in my opinion only finds memory flaws, not instabilities (from overclocking etc - iv seen PC66 ram pass tests @ 110mhz but will not post to windows etc), most of the memory i have seen acts odd when underclocked (eg timings - C5 @ 800, C4 @667) - sometimes iv seen it get worse under clocking, hence why i always suggest MANUALLY CONFIGURE ALL MEMORY SPECS AND TIMINGS.

do u think that 5-5-5-15 is good for this?? or should i try lowering it and/or increasing mhz??

yes this is a GO processor. it idles at 36c-40c and under some load (older games, scans, things like that) the temps never excede 55c. just at prime95 for a few hours it gets that hot. pcie is at its default of 100, and here is all my info as of today

Q6600 (9x333) 3.0ghz Vid is 1.2625v
zalman 9700(temps idle around 40c)
Msi P6N diamond
Mushkin 4gigs (4x1gigs) @800mhz

cpuv is + 0.075v****any less and the comp blue screens constantly, any more and it restarts constantly, this is the only voltage that works.***
NB-SB 800mhz
FSB voltage is at +%12
North bridge volts is at default ( i think 1.25v? may be wrong will double check soon)
South bridge volts is at default(1.5v)
RAM votltage is at 1.8(default) bumped it up to 2.0,2.1, and 2.2. saw no differences. still crashed
5-5-5-15 ram timings, rest on auto

HPET-Enabled
Bit suppoet-enabled
cpuid max val to 3-disabled
IOAPIC function-enabled
ACPI function-enabled
EIST-disabled
Spread spectrum-disabled

i tried increasing the ram's MHZ from 800 to 1066 with thoes settings, and my comp froze.not gona do that again. but im thinking of lowering the mhz to 667 tomorro and il c how that works

and i noticed that my cpuv ranges from 1.26v-1.33v anything else and i got problems. but im still leanin twards the ram or the mobo cuz of the 10hours of prime 95 small ffts.....so ya theres my update fo the day. and thanks everyone for your help.

yes, ive had this system for over a year and it never gave me any problems or crashes. im going to work with it today and il post my results soon. thanks
