RAM Modules: PSD32G133381 Patriot Memory 2GB PC3 - 10600 1333MHz CL9

Ok, so 2 days ago My brothers Desktop started giving problems after his RAM mysteriously gave in, both of them... [Tested]
They were 2GB 800MHz DDR2 1.8v

So first thing we did was head over to the store to purchase him new RAM, we got him 2 x 2GB 1333MHz DDR3 1.5v DIMMs, We installed the 2 without hassle, but after about half an hour of up time his computer gave the first BSOD, We thought ok perhaps something is wrong inside the chassis, so we opened up and made sure everything is perfectly seated and great it was but we could not pin the source of the BSODs which continued to happen from then on.

So after some investigation we noticed that the RAMs CAS Timing was way off, It was set to 7 - 7 - 7 - 20
I ran a memtest to get over 200 errors mainly on test 5 and 8 on both sticks
Confused I Set them to the correct values but then noticing that The only timings I knew were the CL, tRCD, tRP which should be at 9
The motherboards Default settings refuse to set it to the correct amount and insists on keeping it on the 7 format.

After some tinkering we finally got his computer to run a slight bit smoother, but then another error appeared.. Another BSOD, but this time with different details after I set his RAM to the generic CL9 timings

So I am finally out of solutions, I managed to scavenge the Dump files from his PC before it BSOD again but I am now completely tuckered out and thought perhaps I should come look here seeing as I have gotten multiple solutions from here before :). I am at the present moment in time not sure how to open said dump files so if necessary let me know.

If I left out any crucial details let me know, I have been very busy today and have not had a moment to myself all day so errors are bound to occur.

My Thoughts on the matter is that the bios might still think that the DDR2 RAM settings should be used and did not notice the change to DDR3, but that is just a fools thought.
 
The board supports ddr3 as OC. This means you have to enter cmos and allow for overclocking then manually set the ram voltage and timings. I would download ur mobo manual if you don't have it and read up on what to enable/disable. you don;t need to overclock anything else just set the memory to correct values.
 


The problem is I cannot seem to find all the timings on the RAM, the only information I get is it being CL9

[Edit]
I will reset CMOS when my brother gets back home after 2 hours and then go throught the manual and see the specifics I need, However I am unable to find the RAM settings which are required, The only things I know the that the RAM wants CL9

If anyone could possibly help me with the the values for

tRCD
tRP
tRAS
tRFC
tWR
tWTR
tRRD
tRTP
 
usually its 9-9-9-24 i looked around a little and notice they didn't list them on their site either. I ran into the same thing a while ago with a few different companies. Now I make sure when its ram I buy for OC I get the timings before I buy it.
 
Hi

Is this one of the rare motherboards with 2 DDR2 slots and 2 DDR3 slots

What make make & model is it

Is the ram you have fitted on the motherboard manufacturers list of supported RAM for that motherboard

It is rare for two sticks of RAM to fail at the same time, are there any blown or bulging capacitors on the motherboard

best of luck

Will have a look

Edit: Essentially Just reset CMOS and everything is running on default now at startup with the new hardware, will post here again if the problem occurs again within the next 48 hours :)

On a side note though it reset the RAM back to CL7 configuration :/
Also all the capacitors seem to be fine
 
Been out all day, but sadly resetting CMOS did not fix the problem
Still random BSODs

[Edit]
Set it back to the previous CL9 config but it seems to still be giving the same problems
any help would be appreciated :)
