Question Blue screen after new RAM. MemTest86 passed so what is the issue here?

Hello

Motherboard: Gigabyte GA-EX58-UD5
CPU: Intel Core i7 920 D0 Stepping (SLBEJ)
New RAM: HyperX HX318C10FRK2/16 FURY Red, 16 GB, 1866 MHz DDR3 CL10 DIMM (kit of 2)

Absolutely no issues with old RAM (Viper 3x2GB) and system was rock solid, however after replacing old RAM with the HyperX I keep getting blue screen. The RAM checkouts fine by passing MemTest86 overnight but I still kept getting blue screen. Just in case there was an issue with RAM, I also tried another set which also passed MemTest86 but still I'm getting blue screen.

I've tried running at 1866MHz, then 1600MHz and now at it's lowest bios default setting, which is more stable but still eventually blue screens. Any idea what the issue is here please? Can you have a look at my bios screenshots and advise what I might need to change please to make this stable (ideally at 1600Mhz min). The RAM specs state "voltages as low as 1.35 V" and my settings are already at 1.5V so I shouldn't really need to increased this should I?

For some reason this forum won't allow me to insert pics, so have to use links.

Thank you

the thing about ram overclocking is that u cant use auto timings on it (mostly)
your new ram should have XMP profile (one click overclock with predefined timings), but your bios appears to not support it

u can use 3rd party tool to read this data and manualy set it up in your bios
what pops in mind would be aida64
in mainboard -> SPD
here look for Extreme Memory Profile which contains timings u should set up in BIOS

Thank you. That's the thing though, I'm not trying to overclock as you mentioned, I'm simply trying to get this running stable at it's normal speed, heck even by underclocking if I have too (which it currently is), I just need it stable. How do I do that please?

Really know nothing about timings and you are correct my motherboard doesn't have XMP unfortunately.

If someone can look at my bios and state exactly what I need to change, this would be great please.

Your memory kit doesn't have XMP because it's a plug and play kit that should automatically be setting to 1333/1600/1833 which depends on the maximum supported bus speed of your CPU and motherboard, but not always on the newer motherboards. Your max supported bus speed for your i7-920 is 1066Mhz so your memory is automatically set to 1066Mhz. You will have to manually set the timings.

PnP JEDEC TIMING PARAMETERS:

DDR3-1866 CL10-11-10 @1.5V

DDR3-1600 CL9-10-9 @1.5V

DDR3-1333 CL8-9-8 @1.5V

tRAS should be somewhere around 28-32 for 1833, 24-28 for 1600 and 20-24 for 1333. That would be for 1833Mhz 10-11-10-30 as an example. I would leave everything else on auto.

Thank you, but that's the thing the ram is currently already running at 1066 which is underclocked and yet it is still blue screening. That really shouldn't be the case should it, so what is causing this please? My previous ram was 1600 and was running at the same 1066 and PC was rock solid, so what is causing this new ram to blue screen?

Timing only comes into play if I want to reach higher speeds doesn't it? I don't care about speed right now, I just want stability. I'm fine with new ram running at 1066 , but I need it to be stable. What do I need to change in bios in order for it to stop blue screening please? If someone can look at my bios and state exactly what I need to change and where (in layman terms), this would be great please.

Can you post the model of your previous memory kit?

Edit - The problem should be that you are using 8GB dimms when the board only supports 4GB dimms for a max of 24GB in 6 slots.

Previous memory was Patriot PVT36G1600LLK DDR3 1600Mhz 6GB (3x2GB)
Yeah, you just need to get a 4x4GB or 6x4GB kit for dual or triple channel mode or just get a 2x4GB kit and mix in 2 of your 2GB modules for 12GB dual channel mode. You might still be able to new buy triple channel kits with 2GB modules or just check eBay for a decent deal on used.
