How do you explain this? Problem with OCZ / DFI.

Recommended Posts

Ok so you can see my rig below.

 

Also, as an FYI - I am running RGONE's famed bios settings from the sticky. Have been running stable for some time.

 

So, about a week ago (as the price has dropped) I decide I'm finally gonna get the OCZ Platinum PC3200 Rev 2 RAM I should have got in the first place (rather than rev 1.1). This will allow me to have a better play with OCing down the line.

 

I received said RAM and replaced existing RAM - all bios settings kept the same. Booted and stable no issues at all.

 

So tonight I think to myself, with this RAM I should be able to JUST lower the latency to 2-2-2-7 no probs from what I have read (but I am a noob at this kind of tweaking - sorry!). SO I do this - the result being the XP will NOT load - BSOD!

SO I revert the mem settings back - XP now will STILL NOT load !! Grrr (feeling stressed now!)

 

So, I decide to remove one stick of RAM - XP LOADS! Put back other stick - XB does not load.

 

So then I decide to put back in the old OCZ RAM - boots immediately with both sticks!

 

So now I am basically back in the position I was a week ago when I first succesfully put in the Rev 2. So I wonder if I install 2 sticks of Rev 2 again it will now work. Answer = NO !

 

Me not understand!!!! HELP?!!!

 

NB I am running old Bios - 1/25, but as I have had no issues up to now I have not had any reason to upgrade. Could this be part of the cause. Still seems odd when all settings are back to what they were and what worked before does not work now!!!

 

Cheers for any advice!

Hello,

 

Change the timings in the BIOS to this with the old stick, save and exit.

Turn PC off and use new sticks.

 

And if it works try your 2-2-2-5 timings.

 

Command per clock...............Enabled

Cas latency...........................2

RAS to CAS delay..................3

Min RAS active time...............6

Row precharge time..............3

Row cycle time......................11

Row refresh cycle time..........14

Row to Row delay.................3

Write recovery time...............2

Write to read delay...............1

read to write delay...............1

Refresh period.......................AUTO

Wrtie CAS latency..................1

DRAM bank interleave.......... .Enabled

 

DQS Skew Control.............................Decrease Skew

DQS Skew Value................................0

DRAM Drive Strength..........................Level 1

DRAM Data Drive Strength..................Level 1

Max Async Latency.............................6ns

Read Preamble Time...........................5ns

Idle Cycle Limit...................................AUTO

Dynamic Counter................................Enable

R/W Queue Bypass.............................AUTO

Bypass Max.........................................AUTO

32 Byte Granularity.............................Disable(8 Bursts)

Sharp - thanks SO much - that worked a treat!

 

I firstly flashed the bios to 310p but this did not help in Isolation - only when applying your settings could I boot. I then went back and changed to 2-2-2-5 and it boots fine.

 

Now need to run memtest but so far so good.

 

Do you know what the problem might have been and why these settings 'cured' me?

 

Thanks again mate

Hello,

 

It is all about the timings. Setting some to high will not work with lower timings.

 

My own experiments,

Write CAS latency..................1 :)
