Cannot get stable!

danupsher · 19 Dec 2012 at 13:52

Hello!

Ive been having trouble getting my system stable, even a stock speeds.
Heres my specs:

Q6600
p35 ds3r
ocz2g8002g 2gb x 2
500w earthwatts psu
gtx 460

Ive tried increasing q6600 voltage through to 1.6 bios 1.55 in cpuz and it stills fails prime at stock. This board has bad volt drop but im not sure if this is the problem, ive done a pencil mod and this improved the vd slightly but didnt make the system any more stable.

The ram is fine, all setting correct, memtest ok.

ive tried everything... Bad motherboard? bad cpu?

Any suggestions? If i leave the motherboard voltage settings to auto its usable (web browsing) but still fails prime almost instantly. (and auto voltage bumps the cpu to 1.54 idle

)

No one have any ideas?

Bump?

Doomedspeed · 23 Dec 2012 at 23:00

That's an odd problem, Should be working at that voltage.

Does it crash in games also?

Whats this pencil mod of which you speak?

If you've done a few passes of (bootable) memtest and it's OK, then it's either the mobo or the CPU. You'll need to replace one or the other to narrow down the problem. Do you have another 775 chip, or another 775 mobo to test with?

I dont have any access to spare chips or mbs

. Its crashing on youtube vids let alone games lol.

The pencil mod just lowers the resistivity of a resistor on the mb, lowering volt drop. (normally allows for higher overclock on lower voltage)

Is it possible my psu is not providing enough power for this setup?

Bacon? · 25 Dec 2012 at 20:31

Whats your exact make and model for the PSU? If its rebranded crap then the chance is high its causing the problems.

danupsher · 25 Dec 2012 at 20:43

Its an antec earthwatts EA-500D. It came with my case.

danupsher · 25 Dec 2012 at 21:35

Im pretty sure the psu should cope after doing a little research. jus stress tested the 460 with furmark, with no issues. Now my system seems more stable? Can a burn in improve overall system stabilty? The auto volages are lower in speedfan now. And it seems to be running prime 95 ok..

WTF?????

that is fine afaik,

this is at stock speed? imo it sounds like the mobo

danupsher · 25 Dec 2012 at 21:43

Computer just restarted while priming.. I spoke too soon. Yeah its at stock.

danupsher · 25 Dec 2012 at 23:18

Whats going on with my 12v rail?

drops even lower when at idle.

Rroff · 25 Dec 2012 at 23:25

Good chance its the PSU (do you have both slots of the extra CPU power header on the motherboard populated or just 1?) also make sure you have the RAM settings correct and memtested.

danupsher · 25 Dec 2012 at 23:43

Theres a 4pin and 24 pin on this board, im populating both. Is that what you mean?

Rroff · 25 Dec 2012 at 23:49

Forgot the DS3R has only a 4 pin CPU power socket if thats populated thats fine. Some boards have 4+4 CPU power sockets and usually both need populating on those boards for quad cores.

danupsher · 25 Dec 2012 at 23:59

ahh i see!

12v rail is fine, just checked in bios, and with different software.

this is wierd.

j.col · 26 Dec 2012 at 13:41

fire up cpu-z
and check your ram timings match what they say on the sticks and also check ram is getting correct voltage (do this bit in bios)
also iirc OCCT can check the +12v rail for consistent power

danupsher · 26 Dec 2012 at 17:27

The ram is 100% fine. running 5-5-5-18 and is getting the correct voltage. ran memtest for 24 hours with no errors.
Thankyou i will download OCCT and try to rule out the psu being the problem.
