Does anyone know how far you can push 2 sticks of CORSAIR 2GB 1600MHz. It's defualt is 1066MHz in AMD Overdrive, but I have it running smoothly at 1600MHz @ 1.6V and CS 9-9-9-24 with no dedicated cooler. I want to OC it, but I also don't want to burn it out.
WINDOWS 7 ULITMATE 64x running on: MSI AMD 790FX-GD70; PHENOM II X4 965 BE C2; ASETEK 120MM WATERCOOLER; CORSAIR 2GB 1600MHz X2; ATI HD5870 1GB DDR5; CM 850W REALPOWER PRO all in a COOLERMASTER SCOUT CASE.
I don't know what sticks you are talking about. As with all overclocking, the key is to take it slowly. With memory overclocking, you basically stress test in the OS and with memtest. Memtest being the key component to a good overclock. If you find errors then you know that the OC is bad and you need to take it down a notch. Another thing to note is that you can put your hand near the chips to get an idea of how their temperature is. I think it's safe to say that if it is really hot then you should take it down a notch. RAM should really just run warm, otherwise you risk degrading the life span of the chips. Another thing to note is that a heat spreader will definately help and so would good air flow in your case.
The following is a current screen shot of the system memory as i have it now. the sticks are part # CM3X2G1600C9D6 OEM from Cyberpower. If you can suggest any further cranks, then i'd appreciate it. My case is pretty well vented with 3 180MM fans and a lot of mesh. I don't see that as being a problem. Thanks!
I'm not so sure that I would want to play around and overclock ram that doesn't have a heatsink. Well, since you don't have heatsinks, your best bet would be to slowly increase the memory clock speed. But it's still risky without heat sinks. If you go ahead with it, I would recommend touching it while you stress test it. Just remember heat is the enemy.
Also, if you get an error early, DO NOT INCREASE THE VOLTAGE! Since you don't have a heatsink going higher than the stock voltage is not a good idea. You could also try messing around with the latency, but I would advise doing some reading on the topic. I myself haven't delved much into hardcore memory overclocking.
Yea, i wouldn't risk it overclocking that ram. A good set of heat sinks on your ram makes a big difference.
I remember back in the good 'ol days when all ram came without heat sinks and you had t get your own lol I'd imagine there are still people out there that sell them. You might want to go find a good set before attempting an OC
For an AMD system, it is more important to tighten timings than it is to increase RAM speed. DDR3 Cas 6 @ 1333mhz is faster than Cas 7 @ 1600mhz. The lower the timings the better for AMD. For timings to try:
