AMD 939 3000+ MSI K8N Neo2 Platinum problem

[matthewfoley]

I'm really at a loss here. I bought the MSI K8N Neo2 Platinum with a new .90 nm 3000+, with 2*256 OCZ 3700 Platinum R2, planning on oc'ing the heck out of them, but for some reason I can't get past 209 FSB. I've tried every combination in the BIOS that I can think of, disabled the auto overclocking, and I've set the memory timings at 2.5-4-4-10 1T just like in the 939 .90nm review, and set the memory voltage and cpu voltage accordingly as well.

But as soon as I go to 210 FSB I get the safe mode error and the system is defaulted back to 200. I've backed off the CPU voltage and memory voltage one a time to see what the limiting factor is, but nothing at all seems to change 209 as the top FSB I can reach.

Here's an interesting tidbit: in the BIOS under HT frequency there are no options and ESC doesn't work. I have to Ctrl-Alt-Del to get out of it. This wasn't the way it was when I first got the board, only after I flashed the BIOS to the newest version. Also, sometimes the clock multiplier on the CPU gets set at 5 instead of 9.

Now I've successfully reached 240 FSB with this same memory with a Asus P4C800-E Deluxe and a 2.8C P4, so I know it's not the memory, unless it's just that my memory doesn't work well with the 939 chipset, but I've read to the contrary in many AnandTech reviews about this memory. So I'm pretty sure that my problem lies with the board or the proc, and my guess is it's the board.

Any suggestions about a course of action?

just a note: i called ocz and asked what the most compatible ram was for this board , and they told me it was the ddr3700 ddr gold rev. 3 you might want ot call them they are very helpful

The ocz website suggests setting the HT frequency to x4 rather than x5 when overclocking their ram with the neo2 platinum.

I had the same problem as you, however setting my ram speed at 166, and setting HT at x4, I was able to set the FSB at 270 with my OCZ 3500 EB ram. voltages were the sam as AT had them in their review. Also, try relaxing your ram timings a little bit more and see if that helps, then slowly move them back.

Well, I have the rev. 2, which isn't available anymore, but should definitely be ok.

Well, through playing around much, in the bios if I just use the +/- keys instead of hitting enter to bring up the list for HT frequency, I can alter this value. Hope this helps somebody.

I still can't reach the 290 FSB like in the review, but I can get to 265 that's stable with the 1.55V + 8.3% cpu voltage.
