Greetings !
I humbly ask for your help, masters of the PCs ! I have a dire situation which I don't know how to fix it. I consider myself a little expert of the PCs, but this problem is over me and I tried everything in my power and knowledge, with no solution.
My problem is this : I decided to upgrade my old rig, and I bought a pair of 2 x 4GB RAM DDR2 800mhz from Kingston. (code KVR800D2N6/4G). And the PC won't boot up.
My motherboard is ASrock G31M GS R2.0 (http://www.asrock.com/mb/intel/g31m-gs%20r2.0/).
On the site and manual, it's written it supports 8GB RAM.
Also, on the memory QVL (http://www.asrock.com/mb/memory/G31M-GS%20R2.0.pdf), it's written that my memory, the kingston code above, has been TESTED and WORKING on this motherboard !!!
Let me clarify some things first :
- BIOS is already last version available (1.90)
- I tried every slot, with each ram individualy, then together, switched slots between them, same result, it won't boot-up
- before each ram test in each slot, I cleared CMOS, everytime
- there are no bent pins, at all, not on ram pins, not on CPU pins
- I even changed CPUs, first with an E4500 core2duo, then with an Q9650 core2quad, same result, it won't boot-up
- I even tried a primitive solution, to "rub" the rams with a...pencil brush ?, I think it's called in english, to neutralise the electricity in them, no change
But the PC boots up when I use my old ram combined with the new one. But in BIOS, this is the funny part, it recognizes the new ram, it shows "2MB DDR2 333". 2MB out of 4GB !! So total memory shows, 1x2048 + 1x2 = 2050 total physical memory.
In windows, it shows 2GB, so it doesn't recognize the new ram. BUT, oddly, CPU-Z recognizes the new stick, it shows Kingston 4096MB, with all specs.
So after this point, I tried these :
- Memory remapping ENABLED, no change
- Flexibility options ENABLED (which allows better memory tolerance as described in info box), no change
- Tried changing frequency from 667mhz to 800, no change
- All these 3 combined, no change
- I tired to set the memory timings manual, since auto does not work, 5-5-5-15, then 6-6-6-15 (can't go over 15), no change
- I even overclocked the ram, from 1.8V to 2.2V (not at once, raising 0.05V each time), I thought maybe they wish more power, no change
- raised the VTT, from 1.2V to 1.4V (again, not all at once), no change
- raised the NB from 1.3V to 1.35V (can't raise it more than this), no change
I stand here, with no options left, I don't know what to try next. My only theory is, the rams are high-density ones and ASrock bullshited me (us) and they don't work on this motherboard. Please feel free to offer any suggestion, I am willing to try/ test, I kinda need the 8GB RAM nowadays, and DDR2 2x4GB is very expensive and hard to find.
Sorry for any mistypes I've done, I am dead-tired, wrote this at midnight.
Thank you for reading and waiting your oppinions !
