Safe RAM OC?

**Jtsou** · 01-26-2009, 08:29 PM

What ive set in the BIOS:

RAM voltage: 2.0
Manual timings 4-4-4-12
FSB: 400
Everything else is on auto

Is this safe or will my RAM fry?

It is at a 1:1 dram to fsb

On the stick my ram says 5-5-5-18 and 1.9v

**linderman** · 01-28-2009, 11:49 AM

test your setting with orthos and then with memtest.............. at least two hours for both

**Jtsou** · 01-28-2009, 12:07 PM

Ok, but at these settings it will not fry anything will it?

HawMan · 01-28-2009, 12:19 PM

You'll be fine.

Most RAM can cope with 2.1V ( Mines is at 2.1 ), some at 2.2V.

All you've really done is tighten the RAM Timings so you shouldn't have any problems.

**Jtsou** · 01-28-2009, 12:50 PM

So the ram should be faster now? Is there much difference between 5 and 4 latencies?

HawMan · 01-28-2009, 12:54 PM

It should be faster, but i see no difference from CAS5 to CAS4.

**Jtsou** · 01-29-2009, 12:09 PM

What about from 800 to 1066?
I was running prime95 on the torture test and got an error on CPU0 within 30 minutes. But i upped the FSB and ram to 425 when i got that.

**linderman** · 01-29-2009, 12:38 PM

most likely you need to bump the cpu voltage up to 1.35 then test it again at 425

if it will run orthos for an hour without error or heat in excess of about 63C then sneak it down to 1.32 and test again

I wouldnt be so focused on trying to get the ram to 1066mhz as I would to get the cpu stable at 3.8ghz ............... the ram has plenty of headroom thats why the ram wont be the factor in slowing down your goal ............

which cpu stepping do you have ................... look in cpu-z ................. the newer G0 stepping doesnt need or like as much juice ........... the previous ones take it higher

**linderman** · 01-29-2009, 12:54 PM

I hate to bring this up ............ but you have an erratic PSU for really getting good clocks ............ I would pawn that puppy off on ebay and get a corsair or PC Power & cooling unit ............ I have had to many of those "spit the dummy" when pushing them ........... thats why their output power is rated at 40C instead of at 50C like the corsair and PC PC units !

**linderman** · 01-29-2009, 12:55 PM

overclocking puts a wicked load on a PSU ............. good one can take it but weak ones will fold

**Jtsou** · 01-29-2009, 12:58 PM

The Voltages is at 1.25V (auto in bios) but it says 1.25 in CPU-Z, when it is at the 9x Multiplier. It changes between 6-9 multiplier depending on use.

It is C0 stepping.

will report back later.

**linderman** · 01-29-2009, 01:06 PM

bump it to 1.30

**linderman** · 01-29-2009, 01:07 PM

actually try 1.28 first

**Jtsou** · 01-29-2009, 01:54 PM

Ok. ill bump it up in a few minutes.

About the PSU, when i bought the GameXstream it was one of the most quality ones on the market now, and I personally have had no reason to say differently.

I am going to bump it down to 3.6ghz too, 3.8 is over what i really need.

**Jtsou** · 01-30-2009, 04:15 AM

Ran orthos on a blend test.

CPU0 failed at 2hours 41minutes

Code:

Test 1, 270000 Lucas-Lehmer iterations of M420217 using 20K FFT length.
FATAL ERROR: Rounding was 0.5, expected less than 0.4
Hardware failure detected, consult stress.txt file.
Torture Test ran 2 hours, 41 minutes 17 seconds - 1 errors, 0 warnings.
Execution halted.

what were the settings that go with this failure?

what ever the settings they are close to being good to be able to stress test that long before failure ............ sounds like only a tweak is needed

**Jtsou** · 01-30-2009, 12:11 PM

1.275V CPU
425mhz fsb/ram
4-4-4-12 @1.9v

simply go to 1.30 on the cpu voltage ..................... or loosen ram timings to 5-5-5-15
