OK, I finally jumped in and overclocked my DDR2-800 SuperTalent 2GB kit (the one I bought, the set I won has yet to arrive) and have passed memtest86 five times with the settings at DDR2-800MHz-4-3-3- 5-1T @ 2.2V

Is this a good OC? All settings except CAS & Volts are maxed out (If I take the CAS down to 3, I get like 40 errors in test 5). Should I try taking the voltage up or down? Also, memtest86 says the memory is running at 3001MHz; is this good or can I do better?

Thanks,
Kyle

4-3-3-5 1T is very good! You can try 2.3v / 2.4v & Cas 3 if you want but you'll need a fan cooling the ram.

what board is that on... 4-3-3-5 1T is funky to be honest... at 800MHz you should be able to do 3-3-3 1T with 2.2V on 680i SLI... Since you are hitting 1T you must not be on an Intel chipset...

Go download Sandra to benchmark the memory bandwidth and try it at a few settings to see which gives your particular system the most memory bandwidth. If you can hit 3-3-3 1T then you will be a happy camper... Remember to lower the TRC from 23-35 to 12-15.

AMD user?

yeah it's a AMD 5200+ with TT Typhoon on a ASUS M2N32-SLI 590 SLI wireless edition. Also a XFX8800GTS320XXX

I just realize that my FSB is only at 200 so after OCing my CPU, I may not be able to go that high. I'd like to try hitting 3-3-3-5 1T, but I don't have RAM coolers, any recommendations?

Also, about how far do you think that CPU can go on air? What FSB & mult should I start with?

god this is fun and I'm just getting started, may pony up & put it under water in the near future

I was wondering myself what the difference between 2T and 1T was. I currently run 2X512MB Kingston ValueRAM 667MHZ at 4-4-4-12 2T 1.85v. Do you guys think my RAM is capable of 1T? There are no heat spreaders on it.

Sorry if I'm hijacking your thread Alathald.

P.S. I run a X2 3800+ and I got it up to 2.1GHZ with stock cooling. I was limited by my temps, and I didn't take much time into overclocking it anyways.

heat spreaders have nothing to do with being able to hit certain timings, so don't worry about those... If they are getting warm stick an 80mm case fan above them and you'll never have to worry about temps again on the memory modules.

With more voltage most 667 and 800MHz memory might be able to hit 1T... with Value Ram you never know though.

I did finally hit 3-3-3-5-1T at 2.25V with Trc 11, but after installing the set I just won, I had to drop back to 2T...working on my CPU OC, looks like I'm hitting about 3.1GHz, will update soon

How do I test the RAM for stability. Just run memtest?

Congrats Alathald on your new Super Talent RAM. Have fun overclocking.

Yeah, just stick it on a USB or other bootable device, such as a CD and boot up and let it run. I generally run test 5 to check then the default test as a final definitive test (let it run a few passes with no errors and you can call it stabil). If you can't get it to run, make sure the device has a lower boot priority than your harddrive (settings in BIOS)

memtest86 is available here: http://www.memtest86.com/download.html
