OC problems with extra RAM!?!

[warnysouth]

Hi all,

I just upgraded from 1gig of ram to 2gig (same stuff). Previously I was running 2.7ghz with the following setup

e4300 + gigabyte p965 ds3 (F10 bios patch)
1gig Geil PC6400 Ultra (2*512)
6800 GT Extreme
Corsair HX 520 PSU
Tuniq Tower 120

Using stock setup except for:
Memory multiplier=2.0
Bus speed = 300Mhz (300Mhz*9=2.7Ghz)
RAM V +0.1v
Core V 1.35v (+0.025v over stock)
Idle temps <25c, Load temps <50c (TAT) from CoreTemp

Everything else is auto and all the things that need to be disabled are disabled.

So now I stuck another gig of ram in it wont boot over 9*260Mhz!

What should I do to get back up?

Thanks,

W

PS I forgot to revert to stock settings before the first time i booted it after upgrade! D'oh!

What memory divider are you running with, I assume with 300MHz FSB you have 4/5 (thus 375MHz memory clock, DDR running at 750MHz)

If you are running any faster than this you will need to look into adding a little extra vdimm or slacking the timings

Hi,

Memory is at 1:1 CPU-Z says 5-4-4-12

Come'on guys! I know someone has some idea of what's going on here?

Had the same problem when I added an extra gig of ram to my config.

Solved easily: no more auto ram settings (by spd and such) but manually set timings all the way.

OK well I just discovered it will boot at 9*270 if I increase DRAM to +0.2V.

I have no idea how to tune the settings manually - surely the settins depend on the bus speed and therefore have to change every time you increase it?

Seems a bit frustraing I've heard of so many other people overcloking to 3.0ghz+ with practically stock settings.

Any tips?

dont bump the voltage up quite yet.

First, look up the timings specified by the manufacturer for the DIMMS you have, e.g. 4-4-4-12. Make sure that's what you get when you configure the bios.

OK I managed to get it to boot at 9*280 with 4-4-4-12 but only after 4 reboots did it get to windows. Am I right in thinking this means this is NOT stable at this setting?

What's next ?
Thanks,

Just because it takes a few boot attempts before it finally goes through doesn't mean it isn't (or wont be) stable. All that means is that there were minor hangs with the motherboard trying to change the settings. Once it boots into Windows the first time with settings it should work every other time, if it doesn't there are other issues to be found.

Since you've gotten into Windows, the next thing to do is load up both cores to 100% and monitor temperatures to make sure they fall within limits. Once you're satisfied that you have good temperatures you should set about stability testing.
