Added more RAM, Graphics driver keeps crashing

Hello

I've added more RAM to my system. I believe the RAM to be identical or close to identical to what was in the PC originally. Original RAM was likely purchased in 2009. The graphics driver problem did not occur before installing the new RAM.

After installing the RAM the graphics driver keeps crashing.

BASIC SPECS

CPU- AMD Phenom II X4 945
Mainboard- ASUS M4A79XTD EVO
Graphics- Radeon HD 4850, DriverVersion = 8.970.100.7000
Windows Version- Microsoft Windows 7 (6.1) Home Premium Edition 64-bit Service Pack 1 (Build 7601)
DirectX Version- 11.0

Memory- I ran an application called cpu-z and here are the results for the memory. Original memory is DIMMs #1, #2. New memory is DIMMs #3, #4. I notice differences in the results but do not understand what it means. The number F3-12800CL9D-4GBNQ (I assumed this to be the model # when I bought it) is located on the stickers of all 4 units. What is the best way to fix this?

by the part number they are the same thing. You need to go into the bios and manually set the speed and timings for the ram. From what cpu-z is showing your old ram is running at 1600mhz and the new ram is running at 1333mhz

After clear the CMOS, reboot the PC, go to the BIOS to set the XMP profile for the RAM.

All being provided above is nothing more than information, has nothing to do with what they are running at....,and doubt your mobo has XMP as it's an AMD rig..... try manually setting the freq to 1333 the base timings to 9-9-9-27, CR (Command Rate/Timing) to 2T or 2N, DRAM voltage to 1.55 and CPU/NB voltage to 1.18 and give it a try

I figured out how to do everything but set the bast timings. I found an area where I could change some settings to values like 9CK etc. Is this the right place? The 3rd value could only be increased to 7CK

Also, is there any risk in upping the frequency to 1600?

Should be the 4 primary timings together, and are prob currently similar to what I mentioned, if you can't find them try just setting the freq to 1333, leave the rest on Auto, then check the CR and voltages I mentioned...then let me know, if need be I'll dig out a manual and find it for you

I altered the settings as above, with minor deviations to the cpu/nb voltage to 1.175 or 1.185 i cant remember. There was no option for 1.18. It was good for a few days but today again my graphics driver crashed again and later a BSOD occured(I was getting graphics crashes and BSODs much more frequently before-but after installing the new memory)

Try taking it, the CPU/NB to 1.2 (safe)

Been awhile since a crash I think I'm good. Thanks!

No worries, it can take a few adjustments, but sounds like we got it ;)
