Windows 7: New system crashing

24 Apr 2010   #11

Windows 7 Ult, Windows 8.1 Pro,

This can also have to do with the memory settings being used which OCZ Ram is very picky about.

From Newegg reviews these settings need to be used.

Pros: Big difference from DDR2-800 to the DDR2-1066, you can feel it when Vista first loads up and goes into your user account. With DDR2-1066 you wont feel the split second load time and execution you feel with DDR-800. This is also noticeable with program execution and "alt+tabbing" through programs. I bought 2 of these so I have 8Gigs... GG*~! *(internet gaming talk meaning Good Game or Game OVER) Cons: Going through forums and Google Searches, you'll find out that DDR2-1066 is not a normal speed unlike DDR2-800. DDR2-1066 is actually a buffed up DDR2-800, you have to make the adjustments in the Bios to make it run and recognize it as a DDR2-1066. You'll notice in the CPUID program that it's recognizing it as a DDR2-800 or PC2-6400. Just make sure you tweak the DDR2-1066 memory in the BIOS as CAS# Latency (CL) as 5.0 clocks, RAS# to CAS# Delay (tRCD) as 5 clocks, RAS# Precharge (tRP) as 5 clocks, Cycle Time (tRAS) as 15 clocks, Bank Cycle Time (tRC) as 26 clocks, and Command Rate (CR) as 2T. my Cycle Time (tRAS) is auto configuring to 13 clocks, but thats ok, it's running fine. But last but not least, you have to up the Memory Voltage to 2.10 volts. If you are scared to do any of these, stick to DDR2-800 and your motherboard will auto sense it as DDR2-800 no worries. Until Manufacturers make a DDR2-1066 running at 1.8 volts, it will never be a standard speed.

In simple terms you need to set the timing to 5-5-5-15, command rate to 2T and memory voltage to 2.10 volts if you want the memory to run at 1066MHz. You may also need to set the memory to 1066Mhz manually.

OCZ always requires manual adjustments like these, this is nothing new at all. Just read the reviews from Newegg and you will see what it takes to make this memory run stable. Not to mention with your 8GB you may need a slight bump in ICH "north bridge" voltage to get all 8GB stable.

Windows 7 Pro 64 bit

I see where yer coming from, but I altered the settings to what is recommended by OCZ and it was still the same and I know what u mean about upping the NB voltage with all 8 gig installed, BUT I was still getting errors when only ONE stick at a time was in the mobo. Anyway its winging its way back to Overclockers uk now, I'll report back when I get answer from them.
