My memory G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7D-4GBRM

My MOBO GIGABYTE GA-790XTA-UD4 AM3 AMD 790X SATA 6Gb/s USB 3.0 ATX AMD Motherboard

When memory is set to auto on everything, it is detected as 1333 MHz and not 1600.

Also the timings are supposed to be 7-8-7-24 and if I put that I get boot failure. I tried setting to 8-8-8-24 -- 1600 and it would randomly crash.

I had to set my memory to auto to not get crash and it is running 9-9-9-? 1333.......

Any Ideas?

Thanks :bounce:

I had the SAME issues with some ocz gold 1600mhz ram awhile back. Had to be creative with timings to get it 90% stable (yes, only 90) till I RMA'd it, got the new set in and walaa. Works perfect this time under defined timings. Note.. this was 3 sticks of the ocz gold, and EVERY stick was bad. Unbelievable! Then the new shipment worked perfect.

If you're putting in the correct timings and setting the mhz to 1600 manually and it's crashing.. then I'd send the memory back and get a new set.

It's supposed to be 7-8-7-24 2N,
If that doesnt work, then change the 2N to 1N at 1600mhz
Or, just set it to XMP settings, and then change the 2N to 1N

I did set it to 1.635 or something because it supposed to be 1.65 and that was max I could do out of red (1.635)

Also I just started up Starcraft 2 while running FRAPS, itunes, and more programs and after a few seconds my comp crashed and went to blue screen with memory error..... I HAVE EVERTHING ON AUTO lol

I don't get it.. I did a windows memory diagnostic and supposedly everything is fine..

In CPU-Z it says under SPD slot 1&2 (which I don't know what SPD means)... XMP-1600 800 MHz 7 8 7 2t and 1.6V

In Memory tab says Type DDR3 Channels # Dual DC Mode Ganged DRAM Freq: 669.6 MHz and 9 9 9 24 33 1T


PLEASE HELP, this is my first build and crashing from multi-tasking and play SC2 is not my idea of success lol

Please :cry: :cry: :cry:

I manually went in and changed it and when I boot it says BIOS does not match H/W settings and automatically sets it back to 1333 MHZ....and 9 9 9 timings...

How can it do this is I manually go in and change them. After I save and exit it boots and does that.

Also the next screen tends to say No drives found and then says booting operating system or w.e

Dang this is weird,

anyone else have an idea besides RMA for this?
 

I own that ram and run it at the advertised speed on a gigabyte H55 mobo
the rams voltage is 1.6 not 1.65.
http://www.gskill.com/products.php?index=243
on a 1156 mobo it defaults to 1366MHz it required manual adjustments to run at advertised speed
I enabled XMP and adjusted the dram voltage to 1.6v
no problems.
I understand it may be a little trickier on an AMD mobo to get the ram to proper speed.
you won't do it using auto settings it must be adjusted manually

You enabled XMP? How do you do that.

IC, I didn't realize it was 1.6 and what would you suggest for timings at 1600 MHz and 1.6v?

Thanks

Ya when I set it to 7 8 7 24 2 it doesn't allow it on the boot.

on newegg:
Standard DDR3 1866(OC)*/1333/1066
* To reach DDR3 1866MHz or above, you must install two memory modules and install them in the DDR3_3 and DDR3_4 memory sockets.

It does not say 1600

Usually when you're trying to overclock something and the overclock fails, the motherboard will reset back to its previous settings, also. Refering to whats happening to you.

So with those 2 things in consideration... I guess your motherboard isn't going to do 1600

Does that first statement "Standard DDR3 1866(OC)*/1333/1066
* To reach DDR3 1866MHz or above, you must install two memory modules and install them in the DDR3_3 and DDR3_4 memory sockets. "
mean that I should install my memory in the 2x white slots and not the blue slots (1/2)

Also I have 1600 currently working with weird timings such as 8 9 8 25 2t, although I am starting to second guess the crashing to be my video card. It is every time I am in some sort of game with other programs running and if I go to minimize or do something the screen starts spazzing like crazy and Ctrl-alt-del actually gets me away but sometimes it just crashes...

I use a Radeon 5770 Juniper

I just want my comp to run smooth IDC if it is at "Optimal Settings". I just don't want any crashes lol

Also this random Catalyst center is my driver for my GPU?? I looked up drivers for it and it gave me this rando program..

I am having issues with my screen filling my monitor (1920X1080) I had to widen it a bit with catalyst and it still has a few mm's of room between sides and top.


Sorry if I am overwhelming with these issues guys. I really just wish this computer would not crash, fit my screen, and be as fast as it is when it isn't crashing LOL :lol:

You are on vista or win7 right?
Download this:
https://a248.e.akamai.net/f/674/20307/1m/www2.ati.com/drivers/hotfix/catalyst_10.5/ati_catalyst_10.5_hotfix_win7_vista.exe

I have never owned a radeon card, mainly because of all the bad driver reviews. I just don't like the idea of using 3 different programs and having to hassle through drivers to get the hardware to work properly... So I end up paying more for the same performance with nvidia.

I would recommend uninstalling everything related to the graphics card, and rebooting. Go into control panel -> device manager -> display drivers, and delete them. Then reboot. You'll have some horrid kind of resolution probably. Run that file above and reinstall the newest radeon drivers for your card, and reboot again after the installation.

I'm pretty sure thats the driver installer... Like I said I've never owned a Radeon card or worked with one.

As far as the ram, yeah I'd try the other 2 slots and just see what happens if you try to run the ram at the correct timings/speeds. Download memtest:
http://hcidesign.com/memtest/download.html
If you think your ram is stable in the other slots at 1600, then run this for atleast 8+ hours. 1 error means fail, and will cause a crash. Getting your system stable is gonna take some time.

The difference between 1600 and 1333mhz wont be humanly noticable. The benchmark charts I was looking at a couple months ago showed like 3-5 fps difference between 1066->1600mhz ram on 60fps games. After you get everything stable and you get comfortable, then you can try to tweek things.

Every time I have run Memtest it has crashed while I was afk and my computer is off and I turn it on to see windows crashed safe or norm ya know...

This is crazy I will try a few different settings and see if it will get through the test.

If I RMA this memory do they send me a new pair and I send mine back after I get new ones or do I have to send these back first?

Thanks

Depends where you got them.. You have to request a RMA ticket and they'll probably give you a RMA number. Then you'll send the ram back with the rma number on the outside and inside of the box, then when they get the package they'll go through a process of however many days. Then they'll send it back to ya. You'll have to send the full set of ram that was sold to you as a package.
