Hello all,

In December 2009 I bought a new PC, with kinda an old hardware:
Mainboard: Asus M4A785D-M Pro
CPU: AMD Phenom II X4 965
RAM: OCZ 2G10664GK 5-6-6-18 (2x2048)MB 1066MHz DDR2 Gold Memory set; total of 4Gb.
Hard drive: Samsung F3 1Tb

* I'm using on my PC (Windows 7 64-bit) VMware and run on it 2 virtual machines (Ubuntu & Windows 2008 Server)

Any way, a few days a go I noticed that my PC was rebooted 2 times in 48 hours, I checked my hard drive and found 1bad sector.

A few days later I bought RAM: G. Skill F2-8500CL5D-4GBPK DDR2 5-5-5-15; total of 4Gb.

OCZ reseller here in Israel, told me that my RAM will not be for sale any more and he suggested me to buy this one (I bought it directly from him).

Any way, my system now keep rebooting once in several hours, when the system is under heavy pressure, I'm getting a blue screen: bad_pool_caller with codes 0x0..00c2 0x00...007,0x00...00197,0x000...0005110402,0x000..0008a00b08d570

Do you think that it might be caused by the RAM?
Thanks in advance.

hmm... the only thing you recently changed was the ram, however that might not mean that the ram is bad... did you get dual channel ram? are they in the right dim slots? and did you buy the right ram? try plugging your old ram back in and see if it fixes the problem. If it does than you have a ram issue

Oops, my mistake, sorry.

In my board there is 4 slots for RAM, 2 are blue - which the OCZ sticks are installed on - and 2 are black which the G. skill sticks are installed on.

Now totally I'm having 8Gb of RAM, while the main board configured to set clocks\timing automatically.

My board does support dual channel architacture.

your board may be erroring because they are not the same brand of ram or the sam mhz rating or default voltage rating pull out one kit of ram and see if it boots..

The system is running and working fine, but when I'm doing some heavy actions - such as backup 1TB (I have 3 hard drives on my PC) + Browsing using firefox with many tabs the system crash...

OCCT done without any errors.
I will check my RAM with testmem86, hope it can do good teststo m. board with mixed RAM sticks.

definetely not the board... Im using the same board and using 2 different kinds of ram without an issue.

like the board though, its good and has some pretty good OCing potential..

I heard though that that board has trouble running that CPU stable, but that might just have been an idiot who decided to use the 140 watt version, and not the 125 watt version.
