A little help with timings

[kkpudge7]

Hey all, I'm in the process of maxing out my FSB (I want to get to 3.6Ghz), and ive got my cpu holding stable at 3.2ghz, and i'm working on 3.4 right now. My ram is not timed correctly though.

because I cant pass the large fft/ blend tests in p95. My ram is G skill DDR3 rated for 1600Mhz. They factory timings are supposed to be 7-7-7-18. When auto timing is selected it sets them to 8 8 8 24. Either way, they dont pass p95.

I'm not sure if the skew's need to be adjusted or what. Just looking for a bit of guidance to my trial and error lol.

What's your current FSB, NB strap, and DRAM frequency?

[kkpudge7]

Well, for my stable 3.2Ghz (passed 6hrs of small fft) I have the FSB at 400Mhz, with dram set to 1600Mhz. I'm trying to stabilize at 3.4Ghz, with a FSB of 425 Mhz and RAM frequency of 1700Mhz, but I havent gotten that stable yet.

Run Memtest / Memetst86+ to rule out the RAM, at 1700 MHz and 7-7-7-18; 1.9 Vdimm, and post the rest of your RAM timings (sub-timings). If all of the sub-timings are on AUTO, then download Memset and post a pic. w/ it open...

My timings are listed in bios as: 7-7-7-18-5-88-12-6

oops, I just saw that you wanted it at 1700Mhz. I'm only running 400FSB right now, I cant pass blend/large fft at these settings either though, so hopefully this helps.

[redduc900]

I really don't think that RAM is capable of more than about 832 MHz (416 / 1664 FSB) at 1.9 Vdimm and 7-7-7-18... and I wouldn't apply more than 2.0v to it. Like I mentioned previously, run Memtest to test the RAM for stability. And because the Prime Large FFT / Blend test is failing, that doesn't always point directly to the RAM specifically.

[kkpudge7]

Ugh I downloaded this memtest http://hcidesign.com/memtest/download.html and im getting a bunch of errors. It should def run at 400FSB because the ram is rated to run @ 1600Mhz.

[kkpudge7]

Ok, so i'm trying to narrow down my problems. I went back down to the 3.01Ghz profile to test the memory stability.

Thats after about an hour and a half. I tried enabling X.M.P. on the 3.2Ghz profile but that didn't help.

Any input on what I should try next is appreciated.

[redduc900]

You haven't mentioned what your Vdimm is at 1600 MHz... it should be set to 1.9v. And the Memtest / Memtest86+ that I was referring to aren't run within the Windows GUI, they're loaded from a boot CD, thumb drive or floppy disk...

No advice from anyone? lol... I'm getting decently familular with the cpu/FSB settings, but I have no idea where to even start trial and error for this. I'm not even OC the ram @ 400FSB, that is what it is supposed to run at, so I dont know why I'm having such a hard time with this.

Update: I loaded my first OC profile back up (3.01Ghz @ 375FSB) and I passed memtest86. It failed at 400FSB, but I'm 6 hours stable small fft in p95.

[redduc900]

Download either CoreTemp or RealTemp and post the VID of your chip. Seeing as you have both EIST and C1E disabled, the VID as shown in either program should match your current Vcc (Vcore) in Windows at idle (as read by software like CPU-Z, HWMonitor, etc.). If the Vcc is different than the VID (which should also match the default Vcore setting in the BIOS), then you'll need to adjust the voltage in the BIOS, either up or down until the two voltages match. And set all of these options to AUTO...

FSB Termination Voltage
North Bridge Voltage

... and try running Memtest w/ the Vdimm at 1.8v instead of 1.9v, still at 7-7-7-18 and all sub-timings on AUTO.

[kkpudge7]

I tried setting what you suggested to auto and it didnt work :( Last night i was able to get 3 hours of stability on large fft by simply setting my DRAM frequency to auto and then turning on the XMP memory profile.

Not today though, fails immediately on the same settings. I tried messing with the FSB voltages a little bit without luck. I'll try setting memory to 1.8 and memtest86 with that and see what happens.
