Max Bandwidth Causing Hard Locks?

post #1 of 7
Thread Starter 
I've been troubleshooting my computer to try to figure out what the issue is with the hard locks I've been getting about 1-5 times a day over the last couple of months (some days are better than others). No BSOD is given and whatever is on my screen is all I get sozo.gif. After hitting the reset, I am unable to use the keyboard (usb or ps2) when the system recovery screen is shown. I've reinstalled my OS after doing a clean install of all AMD drivers and I've run MemTest86+ (@ 1600MHz) with zero errors after about 10 hours.

I contacted ASUS and reset my BIOS per their recommendation and haven't had an issue until I try bumping the memory frequency back up to 800MHz from 667MHz. I can reactivate all my other settings with no problem except for this. I opened CPU-Z today to do more troubleshooting and found that the Max Bandwidth for each module is registered as PC3-10700H (667MHz) even though the modules are supposed to be 800MHz (image below). I have just contacted Corsair and I'm waiting for a response.

I'm not sure I've chosen the right title for this, but it's the best I can think of at the moment. Anyway, any ideas or advice to help at this point would be greatly appreciated. Thank you.

Motherboard - ASUS Sabertooth 990FX (Rev. 1)
CPU - AMD Phenom II x6 1100T (base clocks)
Memory - 4x4Gb kit Corsair Vengeance ((CMZ16GX3M4A1600C9B) stable @1333MHz right now)
OS - Windows 7 Pro SP1 x64

Not 100% on this but your CPU probably has "Cool N' Quiet" which turns down the clocks of the CPU (which in turn, downclocks the memory) when it's not being used heavily . Besides, by having your CPU at stock, you won't see any performance difference going from 1333 to 1600.

Either that, or it's just 1333 binned to run at higher speeds.

The part showing "max bandwidth" of 10700H (667MHz) is quite normal, and is a value hard-encoded into the RAM itself that usually coincides with the highest JEDEC setting available. I've seen sticks with higher-speed XMP profiles than your DDR3-1600 that have the same "max bandwidth" value, as seen below for this Corsair 1866 kit:

Well that's good to know about the max bandwidth being displayed. I wish it would explain the hard locks though headscratch.gif

Curse the luck, I had another hard lock a couple of hours ago with the memory at 1333MHz. I'm beginning to think it's something on the motherboard since all attached hardware (RAM, SSD, Video, etc) is passing the tests.

You need to open the memory tab in CPUz to get what specs your RAM is currently running at.The SPD tab shows the stock profiles of your RAM.Often times a motherboard bios will not set the proper settings for a given overclocked speed. You may need to increase the RAM and/or CPU/NB voltage to run your RAM at overclocked speeds(which is anything over 1333 on any Phenom CPU).

Set DRAM Frequency, timings, and voltage.

Raise CPU-NB Frequency to 2400MHz

Raise CPU-NB Voltage +0.01V and see how that works.

Cheers
