Corey Posted February 18, 2011 Posted February 18, 2011 ok so long story short. i built my pc last January and sometime during last summer i noticed it was only using 4gigs of ram instead of the 8 that were installed. when i went into the control panel -> system it said 8 gigs installed 3.99 usable. soooo i contact EVGA (motherboard company) about the problem thinking it was the motherboard not reading it. they told me to contact ram company first (g.skill). I contact g.skill and they gladly sent me replacement 8 gigs that had been tested like i asked. so pc runs fine for a week or two then i notice it starts restarting at random times and freezes during gameplay. so i started using 4 gigs instead of 8 and that solved the problem. pc has never given me problems only using 4 gigs. evga wanted me to test each stick in my primary slots to see if ram is bad. well as i was doing so. i noticed that when i tried one stick in a slot my pc blue screened. so i turned pc off and back on with the same stick in and it worked fine. so i asked krausaut today about my problem. he told me to run memtest. I just ran it and here are my results. I have no idea how to read it. I see it says errors but if someone could tell me exactly what that means that would be great. before i ran this memtest computer was using all 8gigs of memory. the test only ran for a few seconds and stopped at 3% with the errors. -ram is compatible with motherboard -running windows 7 64bit -updated motherboard bios -ram speed/voltage manually set in bios motherboard = EVGA P55LE RAM = G.Skill F3-12800CL9D Dual Channel DDr3-1600 Quote
Papito Posted February 18, 2011 Posted February 18, 2011 Are you sure than your Mboard is able or support the 8gb? Did you saw your bios and checked if is enable the use me the 8gb? Quote
SkyeDarkhawk Posted February 18, 2011 Posted February 18, 2011 Just looking at the product pages for each of those, that memory has not been tested with that motherboard/is not certified for that motherboard. Turn your computer off, unplug the power cord, and take out all but the stick of RAM closest to your processor. Plug the power back in, power up your PC, and run MemTest again to see if that stick of RAM still throws errors. If it does, it's just a faulty stick of RAM; depending on your purchase date and other warranty info, you could get an RMA with G.Skill or your supplier to get a replacement part. Quote
milli vanilli Posted February 18, 2011 Posted February 18, 2011 what skye said. and if you DO need new mem, don't mix manufacturers, just get 4 gigs of new stuff. look and see what brands your MOBO recommends. kingston and crucial work with most MOBO's and i've never had any problems with either Quote
Corey Posted February 18, 2011 Author Posted February 18, 2011 ok my mobo doesn't allow me to start my pc up using 1 stick in the first slot. it has to be in the 2nd or 4th slot (primary slots). so i moved the stick that failed in the 2nd slot and tested it for 25 mins. it passed the test 2 times. soo i put all the ram in there and slot 0 had the same 23 errors. so im like ok..... i moved the ram around again. making sure they are in different spots and slot 0 had 23 errors again. so no matter which ram stick is in what slot it stops the test at 2 seconds and shows 23 errors in slot 0. does that mean a motherboard problem with my first slot?

SkyeDarkhawk Posted February 19, 2011 Posted February 19, 2011 Sure does. Double check with your motherboard manufacturer for a RMA/refund policy (EVGA) or see if it is still under warranty (still have your receipt? Can you find the serial number?). Quote
Corey Posted February 19, 2011 Author Posted February 19, 2011 Sure does. Double check with your motherboard manufacturer for a RMA/refund policy (EVGA) or see if it is still under warranty (still have your receipt? Can you find the serial number?). ive already contacted EVGA. With the i5 and i7 series processors the memory controller resides on the processor itself. With the symptoms you describe it is possible that there is an issue with either the motherboard or processor itself. Are you getting any post codes on the motherboards post code indicator while booting? You will want to remove the processor and inspect the socket for any damaged or bent pins as this could cause errors on the one memory slot. If everything looks fine, reseat the processor and test again. Please contact us again so we may further assist you with this issue. Regards, EVGA Quote
SkyeDarkhawk Posted February 19, 2011 Posted February 19, 2011 Try these two tools: Intel Processor Diagnostic Tool (64bit) - This tool verifies the functionality of an Intel® microprocessor. The diagnostic checks for brand identification, verifies the processor operating frequency, tests specific processor features and performs a stress test on the processor. Intel BITS Diagnostic Tool - This tool tests BIOSes and in particular their initialization of Intel processors, hardware, and technologies. BITS can verify your BIOS against many Intel recommendations. In addition, BITS includes Intel's official reference code as provided to BIOS, which you can use to override your BIOS's hardware initialization with a known-good configuration, and then boot an OS. If you aren't running a 64 bit OS (as you should be with that processor and amount of RAM) use this processor tool instead. Quote
Corey Posted February 20, 2011 Author Posted February 20, 2011 going through the RMA process with EVGA atm. just awaiting for them to approve then hopefully ill be home free looks like no et or cod4 for awhile if i send it off :x will be worth it in the end Quote
