Does my mobo/cpu just hate my RAM?

post #1 of 8
Thread Starter 
So I've had this ram for a few years now. They're old Mushkin HP DDR3 1333 CL7 ram (Link to specs) designed to run at really high volts apparently. The thing is, every time that I overclock my CPU past 3.7 ghz, I frequently run into blue screens. I'm not sure why this is, but I know blue screens are usually indications of RAM issues. I've run the sticks at stock specs as well as under downclocked and loosened timings, but no dice, the problem persists. Memtest says the sticks are fine, and large FFTs under prime 95 tell me that the sticks are stable. The funny thing is, when I stess either the CPU or RAM alone (i. e. small or large FFTs in prime, linpack with low memory size, memtest, etc.), I don't get any problems, but then when both are stressed (as is the case in folding and BOINC, prime95 blend FFTs), then I get the BSODs. For things like gaming and the such, there's no problem, however BOINC, which I like to leave on overnight, I often find myself waking up to BSODs. Under conditions of high northbridge/CPU overclocks as well as high CPU/NB voltage (1.35-1.4 V), then I get the BSODs when windows tries to load up. Is this just a case of my mobo not liking the memory sticks, or is there something else that's going on here? I might consider buying some cheap RAM to do a bit of experimentation, but I really like these old sticks because they run good timings.

Thoughts?
Ummm....

It's a divider issue and the RAM can't handle clocks beyond that. You ought to be happy you were able to get 3.7 out of it. 1333 isn't great for overclocking because the headroom is nil to marginal. You'd be better off running 1800/1600~ kits because the dividers are higher and the headroom is available.


The RAM voltage is of little concern. I have sticks that run1.8 up to 1.94 (DD3 1600). Your CPU/NB shouldn't need 1.4v. A lot of people misinformed about it run really high voltage on the CPU/NB when there really is no need. I have a 1055T that does 2500~ at 1.25v and a 955 that does 2800 ~ 1.26v.

I never had the RAM running at the full 1333 though. I usually brought it down a divider such that I had some headroom for overclocking. When you mentioned clocks, did you mean total frequency of the RAM or the reference clock that controls the frequencies?

Both - because the dividers are still low. You only have options of 800/1066/1333 - three total because the RAM most likely won't do 1600. It might do a little under 1450, but you might need an increase in voltage/timings.

With 1600/1800 you're closer to the upper limits and the dividers work all the way down to the lowest frequency. For instance I use a 1333 divider and still have two more above those. You may have a 1600 divider; but can you run it with those DIMMS - that's the question.

For instance - let's say you run a CPU like this:

13x250 = CPU @ 3200~ where as the divider has to be (8) 1333. If you had 1600 Mhz RAM you could run a 10x divider which puts you at 1666. Most boards should see 4 dividers - roughly 6x8x10x12x. You're on the 8x from stock already basically -

Interesting stuff. I didn't really know that there were issues with RAM only being able to handle certain reference clocks. I thought that I could just bump up the reference clock so long as the total frequency was in the ballpark of the rated speeds. Well it looks like I'm going to have to pick up some new 1866 sticks and see if they can help me get past 3.8 ghz. Thanks!

Your best choice: attempt 1600Mhz operation with looser timings, CL9; at 300Mhz bus clock, using x5.33 memory multiplier.  Same performance, probably possible on this kit with similar voltages.

I couldn't get the aforementioned timings to be stable, so I decided to just pick up some new Kingston HyperX DDR3 RAM, but now it seems that my entire desktop got screwed up. All my icons are on my secondary monitor and windows 7 is nagging at me to re-verify my license key, which it apparently can't because of some security issue. I can't move the icons back either. It looks like windows didn't take my RAM upgrade too kindly. Oh well. looks like I might just have to reinstall the OS for these new sticks, hahahaha.
