4GB ram ( 2 GB Usable )

4GB ram ( 2 GB Usable )
This is the message I get when I click on properties ---> computer and look at Installed System Ram. 4GB ram ( 2 GB Usable )

I have tried ram checks, re-arranging the ram sticks, cleaning. I've basically done alot of things that people have suggested over the internet. I really need this 4GB of ram since the things I'm doing tend to need this extra memory.

Please help.

P.S I'm on a 64 bit Windows 7 Home Premium
Motherboard is P7P55D-E ASUS

you might have a bad RAM stick, are you using 2GB x2? one of the stick might be ...(bad)

I have tried that but none seem to be broken.

Out of 2 sticks 1 may be bad. Try installing one (1) ram t a time to find out if both are working fine or not

No I never had any other OS installed. This computer is about 2 months old.

did you try this:
"clear CMOS and reset BIOS, if can't reset your BIOS then at least set back to defaults
and look for BIOS update just in-case there is an important update out there. "

clear CMOS and BIOS like I listed is the only way I believe.

it's worth a shot but depending on how you re-configure it might just be the same.
so do this:
reinstall windows and instead of just formatting the existing partition, to delete the partition and create a new one.
This worked for me where formatting the existing partition didn't.
Also some people solve the issue by enable memory mapping in their BIOS, and/or unchecking maximum memory and number of processors in MSconfig. To do the later hit the windows key and "r" to bring up the run prompt > now type in msconfig > once it comes up click the "Boot" tab >
Now hit "advanced options"
> untick the above mentioned items
> restart.

you need the windows disk and go through the advanced installation process.

cleared out and combined any old partitions, do you have any partitions on this drive.?
actually give me a rundown of your system specs in detail.

Boot into your BIOS and look for a tab called Memory Remapping and tick 64bit if it has one.

No need to go formatting drives mate.

I have done that re-mapping thing in BIOS before and the msconfig thing before. I already tried that and that didn't fix it.

Problems:
1. P55 are notorious for having bent CPU pins {BIOS -> DIMM sees RAM/CPU cannot process}
2. Incompatible RAM - including non-set individual stick purchase/pseudo Sets
3. Incorrect BIOS settings: DRAM Voltage or other DRAM settings, Memory Mapping
4. BAD DIMM Slot(s)
5. Maximum Memory set in Windows
6. Super rare are partitions
7. Bad RAM

Therefore, 'I' need the following simple items to be checked:
1. Post your EXACT RAM**; I prefer a link -> e.g. http://www.newegg.com/Product/Prod [...] 6820220436
2. Clear CMOS check with manual for procedure, or unplug and remove CMOS batter ~15 minutes.
3. Test Slots:
Normal: {CPU) | A2 | A1 | B2 | B1 | ; Dual Channel A1 & B1
a. {Stick test} stick 1 = A1
b. {Stick test} stick 2 = A1 ; If both sticks work individually then no bad stick
c. {DIMM test} stick 1 = B1
d. {DIMM test} stick 2 = B1 ; if both work confirms DIMM slots for Dual Channel
4. Verify the following Windows settings {set per image below}:


After you post your EXACT RAM I will verify compatibly if the information is available, otherwise I'll provide the email/link for a Ticket. If the RAM is indeed compatible then more than likely you'll need to pull the CPU and very carefully examine the CPU pins.

** The exact Part-Number is listed on the RAM itself; otherwise use CPUz {SPD tab} to identify -> http://www.cpuid.com/softwares/cpu-z.html

No wonder, 2000 MHz RAM. Unless you're going to severely OC your CPU then I doubt it will run or run stable; I would suggest that you under-clock the RAM to run at 1600 MHz. If it were 'me' then I would suggest 1600 MHz RAM that is either Certified {QVL} or Tested per RAM Mfg for your MOBO.

BTW - can you edit that really long 'dump' above; 'System Information.'

ASUS P7P55D-E
i7 CPU 870 @ 2.93GHz

BIOS: {see 3-15 - 3-21}
AI Overclocker Tuner -> D.O.C.P. **
DRAM OC Profile -> DDR3-2000 MHz
eXtreme Memory Profile -> High Frequency {failure try High Performance}

DRAM Timing Control {enter}
9-11-9 <- only values published
--
DRAM Voltage -> 1.65v

** Also, according to the datasheet these sticks may be XMP; you can also attempt:
AI Overclocker Tuner -> XMP
DRAM OC Profile -> DDR3-2000 MHz
DRAM Voltage -> 1.65v

Right-off the bat, the BIOS defaults are running the RAM at 1066 MHz which is stock or under-clocking the RAMs rated speed; however neither the CAS or voltage is per spec.

Failure:
1. Clean the DIMM Slots: use Isopropyl alcohol, dampen the RAM contacts and insert in the DIMM slots, clean and repeat.
2. If cleaning fails then download Memtest, create a bootable CD/DVD {ISO/zip} and test for 2 passes - http://www.memtest.org/
3. Memtest failure exchange to new RAM; I'd suggest 1600 MHz.
