All RAM not being utilized plus unsually high CPU Temp


CPU: Core i7 860
MB: GB-H55M-UD2H (Updated BIOS to F8 – Newest)
MEM: Kingston 6GB kit Hyper X 1600
PSU: Corsair 650W
OS: Win 7 Ultimate x64

I am having two problems:

1. Windows reporting 6GB (3.96GB Usable)

2. BIOS CPU Temp 90C, but Easy Tune and Core Temp in windows are reporting ~45C
Both BIOS and Windows suggest the System Temperature is around 40C, no problem there. Using stock CPU cooler, which is affixed correctly and is plugged in and the fan is spinning etc. etc. no visual problems.

Both issues were present before updating the BIOS and still exist after updating

Im using 3 sticks of memory on a dual-channel motherboard with 4 slots, dont know if this is an issue? i have tried different combinations of slots also.

The RAM utilisation isn't a problem. Windows 7 is designed to hold onto system resources to run the OS, and as soon as another application requires resources, Windows will free them up. It is something MS did to aid in speeding up the system.
You should find that when you run multiple applcations with high ram requirements, the memory will be available.

For the CPU temp, I would get a temp gauge and test the CPU itself. Even one that tests food for the right temp would be OK. It has a probe that should be thin enough to put on the actual chip, not the heat sink.

Ok, i will get onto that re; CPU, BUT, with regards to the RAM, what you say doesnt kind of make sense, however, I have built 4 OTHER i7 systems, 3 of them have registered 6GB and no issue with showing a lack of memory, but i did have 1 other that did the same thing, I initially thought it was faulty RAM so took it back and got replacement RAM, the replacement RAM solved the issue and showed the full amount. Why would this issue only occur with some and not others?

Have you tried just using 2 sticks of RAM at a time to see if one stick is sub-standard? seems like one stick is not usable.

Since Windows7 already shows 6GB so i think you should check for option "memory remapping" on Bios to make it usable

i think if the cpu has 90° that you can feel it easily on the heatsink ! (burning hot !!)

What would be the reason for it running at 90C if I am using the default Intel HeatSink/Fan and im 100% its properly affixed (been doing this for years) and that the fan is spinning.....

Would it be a BIOS malfunction, or bent socket pin, or something along these lines. I mean i have updated to the latest BIOS, I don't have access to a thermometer unfortunately. I have put my hands near the heatsink and quickly touched it, doesnt seem hotter than usual.

I cant seem to find memory remapping in the BIOS, looked everywhere, including advanced memory settings. are you sure the motherboard GA-H55M-UD2H supports memory remapping because I know not all of them do...is there some key combinations you need to press to unlock bonus settings??

With the unusually high CPU temp, I found a digital thermometer for human use, as it doesnt display over 42C, but couldnt rech the CPU when the heatsink was on, so what i did was, I left the PC running for 5mins, the BIOS was saying 88C, i turned it off, the second i turned it off, i quickly unplugged the CPU heatsink/fan, which i could easily touch with my fingers instantly, didnt seem like ~90C, then i touched the cpu top layering itself and could keep my fingertips on it for about 5 seconds before it became to hot to touch. Before I did this, i quickly touched the CPU with the thermometer and it read as 39C, i then tried turning on the PC without heatsink affixed and the thermometer gave a reading of HI (or no display) as the temp was obviously above 42C as it does not read above that. I quickly went into the BIOS and it said the temperature was 89C and it stayed there, I did not fluctuate at all, although the System Temperature temperature was fluctuating 1-2C give or take. The comp eventually shut off after about 30 seconds....

I've read your MB's manual and could not find anything about memory remapping either, may be it is enabled natively. However i suspect HPET . Goto Bios --->Power Managerment, find HPET mode and change it from 32bit to 64 bit and see.

thanks for your help Arabia_vn, I located HPET in BIOS and set to 64-Bit mode, but no difference, BIOS still reads 4GB, not 6GB, unfortunately...
I ran memtest and it came up with no errors, so there is nothing wrong with the DIMM's ...

If BIOS reads only 4GB then it should be memory mapping problem, but strangely we couldn't seem to find that option in BIOS. Better email Gigabyte team to ask. If there's really no such option, then that could be Gigabyte advertised this MB wrongly or you got a defective MB. Yes, emailing Gigabyte is what you should do right now.

Have you tried just putting in one piece of RAM at a time and seeing what gets read?
Just put in each one, one at a time and see if that gives any strange readings.

>>   the default Intel HeatSink/Fan and im 100% its properly affixed   <<   same here; yet it happened i've forgot once to remove the sticker (transparant)
if it doesn 't feel hot, the reading is probably false

and yes, RMA looks like the way to go

Ok. i have left the PC running for a while now and no problems with heat, Easy tune has constantly read CPU temp in the low 30C's so the BIOS is obviously giving a false reading for some unkown reason. That, added with the fact its not reading full amount of memory, i have decided i am going to RMA the board. Thank you very much to everyone for all your help.
