4GB (2GB usable)

Hello,

Windows is telling me I have 4GB of ram but 2GB is only usable. This shouldn't happen since I have a 64bit OS.


I have tried:
Turning off the Maximum Memory option in MSCONFIG
Reformat
Memcheck
Tried with Memory Remapping on and off in BIOS

Here is a screenshot of my Resource Monitor



I really don't know what else to do.


I have Windows 7 64bit
Intel i7 870 @ 3.0GHz
ATI 5770 1GB

Any help would be greatly appreciated.
-Ricky

It's the "Hardware Reserved 2050 MB" that is using up the memory. My system only reports 2 MB there.

Hey there thanks for your reply. Can that be fixed or does that stay like that forever?

I don't know. What is your motherboard? Read the manual to see if it is a BIOS setting.

What's going on is that the BIOS has determined the RAM is malfunctioning for reasons unknown: 1. Bad Stick, 2. Bad BIOS setting, 3. (MSCONFIG Max Memory), 4. DIMM Slot failure.

To help the following is needed:
1. MOBO?
2. RAM? I prefer a link to your EXACT RAM.
3. What DIMM Slots are you using?

MOBO - ASUS P7P55D-E
Ram - Kingston 4G(2x2G)2000Mhz PC16000 DDR3 CL9 HyperX

You can try AI OC Tuner-> 'XMP' but I wouldn't with 2000 MHz RAM.

KHX2000C9D3T1K2/4GX -> http://www.ec.kingston.com/ecom/configurator_new/PartsI...
2000 MHz 9-11-9-27-2N @ 1.65v

CPU-z info -> http://forums.ocworkbench.com/showthread.php?t=113139

BIOS
AI OC Tuner -> DOCP
DRAM OC Profile -> DDR3-2000MHz
DRAM Timing Control -> Manual
DRAM CAS# Latency -> 9 **
DRAM RAS# to CAS# Delay -> 11
DRAM RAS# PRE Time -> 9 **
DRAM RAS# ACT Time -> 27 **
--
DRAM Timing Mode -> 2N
--
DRAM Voltage -> 1.65v **
QPI/DRAM Core Voltage -> 1.35v

** IF the CAS Fails then use 11-11-11-30-2N @ 1.68v

Let me know! The settings are correct, the question is can your MOBO + CPU run it...

Just entered those values in BIOS. Everything seems normal what was that meant to do?

No the problem sadly is not fixed.

I tried the 11-11-11-30-2N @ 1.68v configuration but still the same result.

Keep in mind one of those sticks may be bad. Next is a BCLK OC vs DOCP, and is the way to also OC your CPU. You could try DRAM = 1.70v & QPI = 1.40v and it may work but long-term isn't my #1 choice for the rig.

BIOS
AI OC Tuner -> Manual

// http://ark.intel.com/Product.aspx?id=41315 2930 / 133 = 22 stock
// 2930 / 160 = 18.3 assuming you prefer to have your CPU running just above stock vs below; 19
// 19 X 160 = 3040 or 3.04GHz

CPU Ratio -> 19
BCLK Frequency -> 160 MHz
DRAM Frequency -> DDR3-2000MHz ; possible problem '2000' might not be listed, 2008 might or not at all. Q - What values are available? This varies on every MOBO.

DRAM Timing Control -> Manual
DRAM CAS# Latency -> 9 **
DRAM RAS# to CAS# Delay -> 11
DRAM RAS# PRE Time -> 9 **
DRAM RAS# ACT Time -> 27 **
--
DRAM Timing Mode -> 2N
--
DRAM Voltage -> 1.65v **
QPI/DRAM Core Voltage -> 1.35v

** IF the CAS Fails then use 11-11-11-30-2N @ 1.68v

----
edit Failure tests below
----
Failure: Try the other 2 DIMM Slots {Black}

Failure: Try 1 stick at a time; if one fails and one works then the 'failure' is a bad stick.

Failure: Try 1600 MHz @ 9-9-9-24-2N @ 1.65v

Failure: RMA {return RAM} and IMO get a 1600 MHz Set instead. The 2000 MHz add maybe 1-2% but they're all a headache.

Let me know.

Tried Try 1600 MHz @ 9-9-9-24-2N @ 1.65v did not work. I will test the sticks now. How do I do this? What slot do I put the stick in to test.
